Though changing passwords often might seem like a good security practice, in reality, that isn't the case, says Carnegie Mellon University professor Lorrie Cranor. Earlier this year, when the Federal Trade Commission tweeted that people should "encourage" their loved ones to "change passwords often," Cranor wasted no time challenging it. From ArsTechnica's story: The reasoning behind the advice [of changing password often] is that an organization's network may have attackers inside who have yet to be discovered. Frequent password changes lock them out. But to a university professor who focuses on security, Cranor found the advice problematic for a couple of reasons. For one, a growing body of research suggests that frequent password changes make security worse. As if repeating advice that's based more on superstition than hard data wasn't bad enough, the tweet was even more annoying because all six of the government passwords she used had to be changed every 60 days. "I saw this tweet and I said, 'Why is it that the FTC is going around telling everyone to change their passwords?'" she said during a keynote speech at the BSides security conference in Las Vegas. "I went to the social media people and asked them that and they said, 'Well, it must be good advice because at the FTC we change our passwords every 60 days." Cranor eventually approached the chief information officer and the chief information security officer for the FTC and told them what a growing number of security experts have come to believe. Frequent password changes do little to improve security and very possibly make security worse by encouraging the use of passwords that are more susceptible to cracking. The CIO asked for research that supported this contrarian view, and Cranor was happy to provide it. The most on-point data comes from a study published in 2010 by researchers from the University of North Carolina at Chapel Hill.

An anonymous reader writes: Tomas Lindahl, Paul Modrich and Aziz Sancar have earned the 2015 Nobel Prize in Chemistry for their discoveries about how DNA is repaired at the cellular level (PDF), and how genetic information is protected. "Each day our DNA is damaged by UV radiation, free radicals and other carcinogenic substances, but even without such external attacks, a DNA molecule is inherently unstable. Thousands of spontaneous changes to a cell's genome occur on a daily basis. Furthermore, defects can also arise when DNA is copied during cell division, a process that occurs several million times every day in the human body."

Tomas Lindahl first published work in this field back in 1974, when he found a bacterial enzyme that culled damaged remains of cytosines from DNA. He methodically worked out how base excision repair works, and even managed to recreate the process in vitro in 1996. Aziz Sancar's contribution has to do with how DNA repairs damage from ultraviolet light. After struggling to find a lab interested in his work, he went on to show how a group of enzymes identify and excise UV damage. Paul Modrich's focus was on how natural processes corrected base pair mismatches in DNA. He spent a decade laboriously mapping out how each enzyme interacted with this process — an important thing to know, since defects in the repair system can cause cells to turn cancerous.

Koreantoast writes: Black holes, the stellar phenomena that continue to capture the imagination of scientists and science fiction authors, may not actually exist. According to a paper published by physics professor Laura Mersini-Houghton at the University of North Carolina and Mathematics Professor Harald Pfeiffer of the University of Toronto, as a collapsing star emits Hawking radiation, it also sheds mass at a rate that suggests it no longer has the density necessary to become a black hole — the singularity and event horizon never form. While the arXiv paper with the exact solution has not yet been peer reviewed, the preceding paper by Mersini-Houghton with the approximate solutions was published in Physics Letters B.

"I'm still not over the shock," said Mersini-Houghton. "We've been studying this problem for a more than 50 years and this solution gives us a lot to think about... Physicists have been trying to merge these two theories – Einstein's theory of gravity and quantum mechanics – for decades, but this scenario brings these two theories together, into harmony."

theodp writes "When it comes to tales of fake girlfriends, Manti Te'o can't hold a candle to theoretical particle physicist Paul Frampton. In November 2011, writes the NY Times' Maxine Swann in 'The Professor, the Bikini Model and the Suitcase Full of Trouble,' Frampton met who he says he thought was Czech bikini model Denise Milani on Mate1.com. A Yahoo Messenger romance bloomed, at least in the 68-year-old Frampton's mind (Frampton's ex-wife was a self-described 'physics groupie'). But before starting their perfect life together, fake Denise asked Frampton for one little favor — would he be so kind as to bring her a bag that she had left in La Paz, Bolivia? Yep, bad idea. The UNC Louis D. Rubin, Jr. Distinguished Professor of Physics and Astronomy soon found himself in a Buenos Aries prison, charged with transporting two kilos of cocaine into Argentina. Currently serving a four years and eight months sentence under house arrest, Frampton reportedly continues to supervise his two current PhD students by phone, and still finds time to post to the Physics archive."

Frequent contributor Bennett Haselton writes this week with his explanation of how an improved algorithm on the White House's petition-creation site could do away with Death Star petitions and even improve on the existing serious ones. Read on below for his modest proposal on that front.

With a little boost from 4chan, a petition for the U.S. government to build a working Death Star has reached 30,000 signatures and counting, over on the White House's Department Of Let's See How Fast We Can Get 75,000 Signatures To Legalize Pot (or as it's officially known, "We The People"). This is the website where any of the member of the public can create a petition that other users can sign, and if the petition receives 25,000 signatures in 30 days, the White House will issue an official response. (Alan Boyle is taking suggestions on how the White House should respond to the Death Star request. How about: "4chan. You will never find a more wretched hive of scum and villainy.")

Cynics will say that the whole process was already a joke anyway. Even looking at the most popular non-Death-Star related petitions on We The People, most of them express standard left- or right-wing positions on hot-button topics in a manner that's extremely unlikely to convert anyone who doesn't already agree. Since everyone already knows that those some large segment of the population holds those positions, nobody would be surprised that any one of those petitions would be able to gather 25,000 signatures, and so there would be no pressure on the White House to change any of their official positions as a result.

On the other hand, I don't think this means that online petitioning can't work. Rather, I think a sligthly different algorithm could greatly improve the quality of the suggestions that get filtered to the top and trigger a response from the White House. At least one algorithm exists that (a) would prevent the system from being "gamed" by any large, organized group (whether 4chan or the NRA); and (b) would reward the petitions that were supported by the highest percentage of the general user population (or, if you prefer, the petitions that were supported by the highest percentage of credentialed experts in a given field).

The algorithm is the same one that I've advocated for preventing cheating on digg, or identifying the best "hidden gems" among newly released songs (and political arguments), or adjudicating Facebook abuse complaints -- have each petition voted on by a random subset of users registered on the We The People site. Based on this random sampling method, the petitions that have the highest percentage of "yes" votes, are assumed to be the ones with the broadest level of support among registered users, and the ones most deserving of a response from the White House.

Example: Suppose there are 250,000 registered users on the We The People site. A user creates a new petition, and somehow manages to pass some "threshold" that is implemented to screen out blatant time-wasters. (Perhaps you have to gain 100 signatures to pass the first threshold. I'd prefer it if you could clear the first hurdle just by paying $5 with a credit card, but this might anger purists who say that petitioning the government should always be free.) Your petition then gets emailed out to 100 randomly selected other users on the site, who vote to either Agree or Disagree. (In practice, in order to get 100 votes cast, you'd have to email more than 100 people, taking into account their response rate. So if only 50% of users respond to an email request for votes, email it to 200 randomly selected users to ensure you get about 100 votes cast.) Then petitions are sorted according to the percentage of users in their sample who voted to Agree. Petitions that got a high percentage of yes-votes, could be forwarded out to a wider audience (say, 1,000 users), to ensure that the initial high percentages of yes-votes wasn't just a fluke. Users in each random sample could also include comments about why they were voting a particular proposal up or down.

This sounds deceptively simple, but it makes it much harder for an organized online movement to hack the system. Say that 4chan manages to get 25,000 registered users in an attempt to push their favored petition to the top. This still means that, on average, their voters will comprise only about 10% of the randomly selected voters in any online poll - possibly enough to give an extra boost to a petition that already had broad support from regular users, but not enough to achieve a coup all by themselves.

Perhaps you'd object that even if such a system could not be manipulated by organized mobs, it would still leave the approval rating in the hands of non-expert ordinary citizens (even if citizens registered on We The People are slightly more informed than average). Whether you think this is a good thing, depends on whether you think the purpose of the site is to reflect the will of the people, or to provide informed advice to the President.

But if you want to get a random sampling of expert opinions, that's pretty easy as well. For petitions on, say, economic matters, just have a subset of users consisting of economics professors from accredited universities across the country. (These credentials would have to be confirmed manually by White House staff, but it's not that hard to verify that someone owns an .edu address and that their university webpage identifies them as an econ professor.) Then any petition on an economic matter could be submitted to a random sample of economics professors to be rated by them. If a petition gets a rating from economics experts that is wildly different from the rating it gets from the general user population, that suggests something interesting is going on (either econ professors are out of touch, or the general public is misinformed). But if a petition gets high levels of support from the public and the relevant expert group, that would seem to justify a response from the White House, much more so than some of the idiotic petitions currently pulling 65,000+ votes on We The People.

Something almost like this has actually been done by the IGM Economic Experts Panel in Chicago, which surveyed a group of 41 economists that the IGM believed to be among the best in the world, representative of the political left, right, and center. The survey found a high degree of consensus on questions that the general public is divided on, such as the fact that 40 out of 41 experts agreed with the statement:

All else equal, permanently raising the federal marginal tax rate on ordinary income by 1 percentage point for those in the top (i.e., currently 35%) tax bracket would increase federal tax revenue over the next 10 years.

To people who have heard celebrity conservative economists claiming that raising marginal tax rates lowers tax revenue, it might come as a surprise that virtually all expert economists in the IGM's sample, including a representative number of self-described conservatives, agreed that it does not. But don't just soak the rich and call it a day; most economists in the IGM's sample also disagreed that:

The cumulative budget shortfalls in the US over the next 10 years can be reduced by half (or more) purely by increasing the federal marginal tax rate on ordinary income for those in the top tax bracket.

Of course those were questions of fact (what economists call positive economics), while petitions address questions of what should be done (what economists call normative economics, and which varies according to your values and goals). But even economists with diverse political leanings often advocate similar policies; NPR interviewed 5 economists spanning the spectrum from left to right, and found across-the-board consensus in favor of 6 proposals, which you can read here. And hey, one of them is legalizing pot!

If We The People implements a system for polling a random sample of economics experts, I think their first order of business should be to have them rate the ideas in that 6-point platform. The five-person panel claimed that all of these ideas have broad support from economists across the political spectrum, but it would be good to know for sure. And for any of those six points that has broad consensus support from experts, it should be incumbent on the White House to declare whether they agree, and if not, why not.

More generally, random-sample voting will always reveal more useful information -- whether about the opinion of the public, or about the opinions of experts -- than a petition site that lets passionate users self-organize into signature mobs. As I've been saying ever since my first story advocating this algorithm, the only site I'm aware of that currently implements random-sample voting correctly, is HotOrNot, which shows users a random series of pictures and lets users rate the picture's hotness on a scale of 1 to 10. Can we not make at least that much effort to design a working system, when it comes to deciding which petitions get a response from the White House?

Gunkerty Jeb writes "Side-channel attacks against cryptography keys have, until now, been limited to physical machines. Researchers have long made accurate determinations about crypto keys by studying anything from variations in power consumption to measuring how long it takes for a computation to complete. A team of researchers from the University of North Carolina, University of Wisconsin, and RSA Security has ramped up the stakes, having proved in controlled conditions (PDF) that it's possible to steal a crypto key from a virtual machine. The implications for sensitive transactions carried out on public cloud infrastructures could be severe should an attacker land his malicious virtual machine on the same physical host as the victim. Research has already been conducted on how to map a cloud infrastructure and identify where a target virtual machine is likely to be."

theodp writes "Enough with the dadgum naysayers. Google's Vivek Haldar lists some good reasons for why you would want to program at fifty (or any other age). Haldar's list would probably get a thumbs-up from billionaire SAS CEO Jim Goodnight, who had this to say about coding when interviewed at age 56: 'I would be happy if I just stayed in my office and programmed all day, to tell you the truth. That is my one real love in life is programming. Programming is sort of like getting to work a puzzle all day long. I actually enjoy it. It's a lot of fun. It's not even work to me. It's just enjoyable. You get to shut out all your other thoughts and just concentrate on this little thing you're trying to do, to make work it. It's nice, very enjoyable.'"

mikejuk writes "You might think of linguistics as being interesting but not really useful.

What is surprising is that though they are encrypted, the frames that make up a Skype call contain clues about what phonemes are being spoken."

Andorin writes "Anyone familiar with the piracy debate knows about the claims from organizations like the RIAA that piracy causes billions of dollars in damages and costs thousands of jobs. Other studies have concluded differently, ranging from finding practically no damages to a newer study that cites 'up to 20%' as a more accurate number (PDF). I figure there's got to be an easier way to do this, so here's my question: Does anyone know of any creative works that were provably a financial failure due to piracy? The emphasis on 'provably' is important, as some form of evidence is necessary. Accurately and precisely quantifying damages from p2p is impossibly hard, of course, but answering questions like this may lead us to a clearer picture of just how harmful file sharing really is. I would think that if piracy does cause some amount of substantial harm, we would see that fact reflected in our creative works, but I've never heard of a work that tanked because people shared it online."

Dave Knott notes that Google has announced it will close its online cell phone store and no longer sell the Nexus One smartphone directly to consumers. "While the global adoption of the Android platform has exceeded our expectations, the web store has not," wrote Andy Rubin, a Google vice president of engineering, on the official company blog. "It's remained a niche channel for early adopters, but it's clear that many customers like a hands-on experience before buying a phone, and they also want a wide range of service plans to chose from." From the Globe and Mail article: "At least one aspect of Google's attempt to disrupt the world of mobile communications — selling phones directly to customers — has failed. ... [T]he decision to design and sell the Nexus One was perhaps more potentially disruptive for carriers. ... Google plans to continue marketing the Nexus One through 'existing retail channels, essentially partnering with carriers around the world. The Nexus One web store, meanwhile, will essentially become a marketing portal 'to showcase a variety of Android phones available globally.'"

Dave Knott writes "A thirty-member Spanish medical team has achieved the world's first full face transplant. There have been ten previous similar operations, but this is claimed to be the first total transplant, replacing all of the face including some bones. The unnamed recipient originally injured himself in a shooting accident, and received the entire facial skin and muscles — including cheekbones, nose, lips and teeth — of a donor. The complex operation involved extraction of the donor's face, followed by removal of the jaw, nose, cheeks and parts of the eye cavities. Then the medical team took all of the donor face's soft tissue, including musculature, veins and nerves. In order to transplant the face, the medical team has to connect four jugular veins, extract bones and join all the musculature and blood vessels. The recipient has had a chance to see himself in the mirror, and is reportedly satisfied with the results. It is unknown whether he now looks more like John Travolta or Nicolas Cage." The pictures and videos in the linked articles are all computer-generated at this point, so the squeamish need not worry.

Citing Apple's press release: 'Although we have delivered more than 500,000 iPads during its first week, demand is far higher than we predicted and will likely continue to exceed our supply over the next several weeks as more people see and touch an iPad. We have also taken a large number of pre-orders for iPad 3G models for delivery by the end of April.' International pricing will be announced on May 10, at which time international pre-orders are expected to begin."

The complaint specifically relates to photo preview functionality which Kodak claims infringes on their patents. The company is asking for unspecified monetary damages and a court order to end the disputed practices. Kodak has amassed more than 1,000 digital-imaging patents, and almost all of today's digital cameras rely on that technology. Kodak has licensed digital-imaging technology to about 30 companies, including mobile-device makers such as LG Electronics Inc., Motorola Inc., Nokia Corp. and Sony Ericsson, all of which pay royalties to Kodak."

Dave Knott writes "The notable science fiction screenwriter and director Dan O'Bannon has died at the age of 63. O'Bannon's career began with a writing credit for John Carpenter's Dark Star and he went on the write many enduring science fiction and horror films such as Blue Thunder, Lifeforce, Screamers and Total Recall. He was also an occasional director, whose credits include The Return Of The Living Dead, the campy horror film that made popular the zombie chant of 'braaiiiinnnsss.' However, he will be best remembered as the writer of Alien, one of the all-time classics of both the science fiction and horror genres. O'Bannon died after a 30 year battle with Crohn's disease and is survived by his wife, Diane, and son, Adam."

Dave Knott writes "Entertainment Weekly reports that Universal Pictures has confirmed rumours of a Battlestar Galactica feature film. Directed by Bryan Singer, and co-produced by original series creator Glen Larson, the new movie will not be related to the recently concluded SyFy Network series.

Wright and EA will co-own Stupid Fun Club, which will focus on developing new cross-media IP for games, movies, TV and toys. EA has the right to develop game concepts that emerge from the think tank, and both the company and Wright have an equal stake.'"

Nine science professors and one science fiction author are asked to give (mostly) realistic hypotheses of the ways in which the planet Earth and its inhabitants can be destroyed. These possibilities for mankind's extinction include super-volcanoes, massive gamma ray bursts, and everybody's favorite, the killer asteroid. Perhaps the most terrifying prediction is the reversal of the Earth's magnetic field (combined with untimely solar activity), a periodic event which is currently 1/4 million years overdue."

Quoting Tennant: 'When Doctor Who returns in 2010 it won't be with me. Now don't make me cry. I love this part, and I love this show so much that if I don't take a deep breath and move on now I never will, and you'll be wheeling me out of the Tardis in my bath chair.' Tennant will appear in a Christmas special, titled The Next Doctor, before filming four more specials in January. After that, the search will be on for the actor to play the 11th incarnation of The Doctor."

carolinamagi asks: "I've got an original Playstation collecting dust in my garage that I only use when I've got a fix for Final Fantasy VII. I know the original Playstation is a dated system but I can't help but wonder if there are any 'after market' or non-game mods which others have tried (with success) to give their Playstation some new life. The catch is that I'm a total novice when it comes to mods (although I am handy around the house and around a computer) and I would still like the ability to play games with my modded Playstation. Any ideas?"

An anonymous reader writes "The Graphics research group at the University of North Carolina at Chapel Hill has posted some interesting benchmarks for a sorting implementation which is done entirely on a GPU. There have been efforts on doing general purpose computation on GPUs before (previous Slashdot article). However, most of them had generally utilized the fragment processing pipeline of the GPUs which is slower then the default high speed rendering pipeline. Apparently, the above implementation is done using "simple texture mapping operations" and "cache efficient memory accesses" only. There also seems to an option to download the distribution for non-commercial use, though the requirements seem pretty hefty (a very decent nVidia graphics card and the latest nVidia drivers)."

rrwood asks: "I'm starting work on what is more or less an open-source 3D modeling application, and I'd like to make it as cross-platform as possible (Linux, FreeBSD, Windows, MacOS, etc.). OpenGL takes care of the 3D rendering I'm going to need, but I also need some sort of widget set, and I'm looking for advice as to what to use in that regard. I've done my Google homework and have come up with the following, but would like feedback from anyone who has already used any of these, or has recommendations about anything I may have missed. Yes, I know about Blender, and be reassured I am not planning on reinventing that wheel, okay? :-) So, here's what I've found so far. As I said, if anyone can add to this list or share his/her experiences actually working with any of these, that would be greatly appreciated."

"GLUI provides a flexible windowing system and a rich selection of widgets (buttons, checkboxes, radio button sets, spinners, text boxes, arcballs, dividers, packing panels, packing columns, etc.). GLUI's design is very straightforward, and the docs and examples are extremely well done. GLUI is highly portable, since it depends only on OpenGL and Glut.

GLOW is 'a cross-platform object-oriented framework for building interactive applications using OpenGL or similar APIs such as Mesa.' GLOW is basically an elegant C++ wrapper around Glut, providing push buttons, check boxes, radio buttons, scroll bars, sliders, text fields, menus, etc. This is a really nice description of GLOW, including comparisons to GLUI and MUI.

Speaking of MUI, Steve Baker's advice is basically 'just don't.' Instead, Steve recommends PUI, which he wrote. :) Actually, he speaks very highly of GLUI, and does a nice job of pointing out the subtle differences between GLUI and PUI.

PUI is part of PLIB, a rich and vibrant set of libraries for cross-platform game development. This is a wonderful intro to PUI. Go read it right now. Really. PUI itself does all the sorts of stuff I'm looking for, and perhaps more. It looks to be very stable and mature, too.

LibUFO is a C++ widget set for OpenGL, currently in alpha. Features include pluggable look and feel, theme support, and layout manager support. LibUFO can be used with GLUT, SDL or any native GL context, so it is highly portable, too. Except for the fact that this is only alpha code at this point, it looks quite nice.

FOX is a C++ toolkit for developing cross-platform GUI apps. It seems like a fairly standard C++ framework, with built-in OpenGL widgets, too. By all accounts, FOX is quite mature and stable, with a fairly active developer base. FOX supports many OSes, but not, unfortunately, the Mac. And yes, I could easily hack out Mac support myself, but I don't want to do that-- I want to write my app.

FLTK is another cross-platform C++ GUI toolkit with OpenGL support. The advantage of FLTK over FOX is that FLTK supports MacOS X (not 9.x and earlier-- too bad).

DirectFB is a library built on top of a framebuffer device such as the Linux framebuffer or SDL. There seems to be some 3D support in there via DirectFBGL, though the docs say that there is no hardware acceleration support (i.e. Mesa vs OpenGL). The thing that makes DirectFB particularly attractive is the fact that Gtk/Gdk has been ported to it.

SDL and ParaGUI are also an attractive option. SDL is insanely portable, and ParaGUI is a wonderful GUI/widget toolkit that runs on top of SDL. You really need to see the ParaGUI demos running to appreciate how slick it is. The screenshots are nice and all, but they don't do it justice. As well, ParaGUI is really slick in its support for themes, XML, and Python.

PicoGUI was a recent SlashDotting victim. As mentioned at that time, PicoGUI is actually a sophisticated client-server framework, capable of running in a wide variety of environments, including on top of OpenGL. There is plenty of info at the PicoGUI FAQ, including a few comments that suggest it would be a perfectly reasonable choice for what I'm looking at doing. Given the scope of what PicoGUI is trying to achieve, I'm a little nervous that it might be overkill for what I want to do.

Fresco is another client-server framework which some may have previously known as Berlin. Fresco seems very cool, but again, I suspect it is overkill for what I'm doing.

The GUI Toolkit/Framework Page is also an excellent resource for cross-platform development of all stripes.

And the OpenGL Toolkit FAQ is also an excellent resource with special emphasis on OpenGL."

gunnk writes "In today's large intertwined networks it is awfully easy for a bug in one piece of software to have far-flung ramifications that may be horribly difficult to track down. For example, think about the chaos that could ensue if Cisco had a subtle routing bug in it's next generation of internet switches. Unfortunately, it is too expensive to build a test environment anywhere near the scale of the real environment, so the final "testing" occurs in the real world. A new idea has come along, however, that might just help: creating a virtual world in the real world network to test the software (with the added bonus of being able to step backwards through the process to analyze bugs). Sciencedaily is running an article on this method entitled "New Computer System Solves Problems by Tricking Computers"."

Okay, here are answers from Paul Jones, director of ibiblio.org. You asked, and he responded -- and not always as seriously as you'd expect from someone who can ask us to call him "Professor Jones" or "Doctor Jones." But he's really "Just Paul," he says, "even in class." We hope a whole lot of you have a chance to meet Paul in person one day, because he's not only a warm and friendly guy, but one who has done a whole lot of good for Linux -- and for the Internet in general.

Paul:
Let me start out with a little overview of sunsite.unc.edu/metalab.unc.edu. Or better yet to point you to our annotated timeline. Then say that ibiblio.org began and has continued to be a way for the University of North Carolina (the original and still the best) to explore information sharing in the context of our missions of education, research and outreach. You folks using and contributing are the outreach part. In particular, we "acquire, discover, preserve, synthesize, and transmit knowledge" with all of your help.

We are a joint project of the School of Information and Library Science (there we are involved in digital archives and digital libraries), The School of Journalism and Mass Communication (there we are involved in electronic publishing and multimedia sharing), and the Vice Chancellor for Information Technology.

Except for one and occasionally two full time employees, our entire staff consists of students or in my case part time (as I have faculty responsibilities). So be nice to all of us, we're always learning. No matter what Robin said in the article introducing me, none of this would have happened without some very good people on staff and contributing content.

But that brings us to:

Question of Money
by too_bad
One of the things that people frequently ask about sites like ibiblio.org is "They are great. But how long will they be around?" Do you see this as a concern (esp. after the LWN announcement) and do you have any comments regarding this. Are there any good approaches you suggest (like augmenting free usership with voluntary subscriptions, etc) for such free sites in general?

Paul:
We have been very lucky, since our beginning, to have generous and understanding support from The University of North Carolina and from sponsors large and small including Sun, IBM, Red Hat, VA Linux^h^h^h^h^hSoftware, Mandrake, Cisco and others.

We also do get some research contracts and grants, but most importantly for us in the past two years has been a large gift from the founders of Red Hat and the Center for the Public Domain.

We have some top secret international funding sources as well. At the moment, we actually have a small endowment that if spent wisely should last several years. It is my hope that we will never have to charge the patrons of our digital archives.

BUT this brings me to my favorite question, which only got a rating of 4:

Typical Questions
by suwain_2
I've downloaded my share of things, and find that the 3 Mbps cap on my cable modem is almost always my bottleneck. So my question is fairly simple (albeit broad) -- can you describe your setup a bit, in terms of bandwidth (both what you have for an Internet connection, and how much traffic you actually use), servers, storage (I'd venture to guess it's to the tune of several terabytes?), etc.

Paul:
We're on UNC's network. Our connections to the commodity and Internet2 networks are served by UNC's OC-48 network connection. We maintain a constant throughput of network traffic outbound in the 160-180Mbits/sec range.

Our current main servers were donated by IBM and serve content from a central fileserver with 2TB of disk attached. In our racks, we have approximately 5TB of space (with system disks, Sourceforge and an Internet2/Distributed Storage Initiative node). We do some load balancing between streaming services, web services, and large downloads like distros. On a typical day, we move over 1.5 terabytes of data off our servers. (Thanks to Fred Stutzman for much of this info.)

Backups
by Chris Pimlott
What's your backup strategy? I imagine it's hard to deal with both so much data as well as being under constant bombardment from clients around the world. How often is data archived? Have you had any major data loss incidents and, if so, how well were you able to deal with them?

Paul:
Like everyone else we rely on Archive.org, but seriously... (Fred answers this since he did the restore).

We run managed backups on UNC's enterprise storage facilities. We run them every night and have incremental backups for three months. UNC uses StorageTek machines and Tivoli Distributed Storage Manager for enterprise backups. We have had major data loss incidents, in which a raid card failed and lost the array's configuration. One of the disks in the array died simultaneously, we were unable to re-import the configuration to the new card, so we had to restore from backup, which took a number of days.

I, Paul, can only say that in the past things were much worse and we did have one famous meltdown in 1995 that was not pretty. Since then the UNC enterprise backup has been our friend - and for the most part disks and RAID arrays have been increasingly more reliable.

What's your biggest area?
by Otter
I know ibiblio (I still think of it as SunSite) as a) a repository of Unix software, especially useful for pre-Freshmeat apps and b) a mirror provider. "Free online publisher" wouldn't have made the list, but looking at your main page I see all sorts of things I didn't realize you hosted. Which ones get the most traffic?

Paul:
For sheer bytes, ISOs rule. But then it doesn't take too many downloads to get a lot of bytes for an ISO. Source-based distros like Gentoo have seen a lot of activity lately.

One of our most visited sites is also one of our oldest, Nicholas Pioch's WebMuseum (originally WebLouvre). An amusing reason may be that, as Nicolas writes:

"I've just found out that Microsoft Encarta Deluxe 2001 (the copy I just happened to find out and install) has direct links ('Web Links') from each artist's article to the webmuseum (on metalab.unc.edu at the time) and that's actually the only weblink provided in that 2001 edition."

What about content producers?
by Fluid Donkey
In general how supportive have you found the producers of such content to be of your services? Do many if any really believe that something like this will cause them to starve to death?

Paul:
First, they are all with us voluntarily and can leave any time, taking their stuff with them. That alone pretty much says that they believe in what we are helping them do.

I should say also that not all material is copyleft. But all of it is free to view, listen to and to reference. We are working with Creative Commons, which we also host, to develop a small but viable set of licenses for folks including our contributors who want to share their work on various terms (attribution, home or personal use, educational use, etc).

One important contributor, Roger McGuinn, has been making one folk song a month available for download since November 1995 on his Folk Den. He also sells CDs and performs concerts. He seems to be doing pretty well. Many contributors are scholars or students who understand the importance of sharing information.

Dave Farley, who does the wonderful Dr Fun, has a book contract with Plan 9, and we're looking forward to seeing what we've seen in electrons in print.

Relative importance of different material?
by kafka93
What is the center's view on the publishing of material that might be considered "offensive" or "dangerous", and does the center make subjective judgements upon the importance of one piece of intellectual property over another on the basis of 'artistic worth', 'decency', etc.? With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law. Ultimately the contributors are responsible for their content and we do not review the content once a project is taken on.

Most rejections of content come about because the content is too commercial, just personal, or relies on advertising.

Metadata and easy searching
by RyanMuldoon
iBiblio stands out as an excellent repository for a wide range of culturally valuable resources. As it and other sites grow in size, the importance of good searching and indexing becomes extremely relevant. Have you given any thought to how you might want to cope with this? Specifically, are there any metadata schemata that you are considering using? I would love to see iBiblio be used more like a content feed to research/cross-referencing applications.

Paul:
Interesting that you asked about this as this is an area that we've been working in for the past couple of years. Actually we go way back to pre-Web metadata to the Internet Anonymous FTP Archive (IAFA) files which were the model for the Linux Software Map (LSM). Thanks to Jonathan Magid for this innovation and for suggesting that we host Linux in the very beginning.

When we designed our contributor-maintained Collection Index, we designed it to create and display metadata that could be shared via the Open Archives Initiative (OAI). Please note that this metadata is at the collection level - not at the item level. Item level metadata is for future work. Also since you asked: Miles Efron and I will be presenting a paper at the Digital Resource in the Humanities conference in September on the Problem of Access in Contributor-Run Digital Libraries. Serena Fenton is co-author to this paper.

On the Linux Documentation Project front, we worked with several others to create the Open Source Metadata Framework (OMF).

The OMF aims to collect data about Open Source documentation, or metadata, that will be used to describe the documentation. The idea is that the OMF will act as a sophisticated card catalog type of system for the numerous Open Source documentation projects that exist. The OMF offers a number of advantages over standard card catalog type systems, however. Chief among these is the fact that the OMF has been designed from the ground up to be completely open, standards based, and sharable. We will accomplish this by using pre-defined standards (XML and the Dublin Core description for metadata) and allowing all metadata generated to be accessed by anyone that wants it. Because the metadata itself is to be stored in XML files, anyone should be able to use it.

OMF support is included in the Scrollkeeper project. Note that none of these metadata designs are overly complex. That is by design. The idea is to keep the metadata simple enough to be understood by the creator of the digital item or collection that it describes. If I could make one strong point about metadata design it is that simplicity is the key - and the hardest thing to pull off.

Trust metric and online publishing
by Creosote
I heard you talk at the Southern Presses conference last year about the use of trust metrics (like Slashdot's karma and Advogato's peer certification) as a possible alternative to the "top-down" means of filtering that scholarly and commercial publishers use, namely formal peer review and mass marketing, respectively. Are you more or less optimistic about the long-term viability of this model then you were then? (Especially in light of the powerful efforts to keep control of the gates we're seeing these days from Hollywood, the recording industry, and their political allies...)

Paul:
Beginning here I am speaking personally and not on behalf of ibiblio.org or any of its sponsors or supporters including but not limited to the University of North Carolina.

The Blog is one example of creator-empowerment that has gotten more attention since that talk and I think there will be plenty more examples to come. I still believe that people in constant communications will result in "Smart Mobs" (thank you, Howard Rheingold, for naming and noticing and writing on this). This is not just about music or movies or about one country or even one age group. While I don't think that we will completely replace our reliance, however reluctant, on Mickey Mouse, I do think that we are entering a time in which there are new opportunities for us to share information and to work together. The slew of misguided efforts by media and information cartels, especially the RIAA, which demonize their customers and clients, will make things tough but they also are signs that the old solutions are not working well and that newer, and I hope more inclusive and more open, solutions are on the horizon.

GeekPAC and "When Congress Attacks"
by lunenburg
I noticed that you are one of the founders of the American Open Technology Consortium and/or GeekPAC - the lobbying group that got a bit of fanfare a few months back when it was formed, but has been pretty quiet since then. With Congress launching seemingly daily attacks on our technological freedom in order to support the revenue models of a few huge businesses, the need for a voice in Washington is growing urgent. Is the AOTC/GeekPAC working to get our voices heard? Is there a need for an umbrella group to tie together various groups like GeekPAC, Public Knowledge, Digital Consumer, etc.?

Paul:
Yes, (again speaking only as Paul) I am an officer of the American Open Technology Consortium (AOTC). But for various complex reasons, I am not a member of GeekPAC. As you might have guessed, getting these projects going has been no simple matter. Jeff Gerhard has been doing a wonderful job of making sure the legal and procedural steps are properly taken. So far, what you are seeing is some very motivated but very busy people learning how to work together to get the projects off the ground. The good news is that folks like Jeff, Doc Searles and others on the boards are smart, dedicated and experienced people who can and will play well with others (including Public Knowledge and Digital Consumer and EFF). We hope to represent slightly different voices than those already represented. If you are reading this, you know who you are and we need your help.

About the umbrella group, I think that a summit conference (or at least a summit listserv) would make more sense. This kind of looser structure, often called an Action Committee or Organizing Committee, has been very successfully used by both ends of the political spectrum in the past half century.

Two words...
by Anonymous Coward
DRM? Palladium?

What's your take on these two technologies?

Are you afraid they'll ultimately destroy what you have been working for, for the past 10 years? If not, why?

Optional question: What about the copyright extension we have seen?

Another optional question: Linux... or BSD? =)

Paul:
Not Linux vs BSD, but Digital Rights Management and Microsoft's Palladium. DMR is the general term for the groups of solutions to the need for creators to be compensated for their work while allowing their audience to easily access those works. Or at least that would be ideally what DRM should do.

When DRM goes wrong, it tramples on the rights of the citizens to have access to information that they have legally purchased, want to criticize, parody, legally reuse or share.

When DRM goes wrong, it creates barriers to innovation and creativity. It biases access and reproduction of information to only certain technologies.

When DRM goes wrong, it creates and perpetrates closed markets and monopolies.

When DRM goes wrong, everyone suffers. It takes us back to the Stationers Guild, a response to the printing press. "The Stationers Guild obtained monopoly rights in the printing and probably distribution of all books, a monopoly codified by the Tudors in a licensing system aimed at censoring religious dissent" which lasted until the early 1700s.

When DRM goes wrong, it is called Palladium.

The good news is that Palladium is vaporware - so far.

What is your greatest success/failure?
by burgburgburg
Simple enough question in two parts:

Looking back on 10 years of doing this, what would classify as your greatest success, and your greatest failure?

Paul:
The simplest question is the hardest, of course. Luckily, you've narrowed the success/failure question to deal only with sunsite/metalab/ibiblio and not the past 10 years of my life.

One mark of great success is that we are still here hosting some of the original collections of information to be shared on the Net including the first 7/24 radio simulcast on the net, WXYC. We've been a part of many innovations and I, personally, have been able to work with some brilliant folks who often surprised themselves with what they had accomplished. We're also funded and we enjoy support from some wonderful and diverse faculties at UNC.

There is no question in my mind that the most significant decision that I made in those ten years was to listen to Jonathan Magid when he suggested that we become the US site for an operating system that didn't even work yet - Linux. If you are reading this far and are happy, you owe Jonathan. If you are unhappy, blame me.

In research, there is no such thing as failure. As I was explaining to our Interim Vice Chancellor, we are supposed to make mistakes. As Ms. Frizzle says, "Take chances, get messy and EXPLORE! Wahoo!".

Still, I do wish that we had found a way to use WAIS or another distributed search engine in a way that is still useful. There still seems to me to be something unfinished in that area. Killing gopher. That was more fun than Wack-a-mole.

And one final answer:

Slack.
by dsb3
You host a slew of subgenius content, so it must be asked ... do you have slack?

Paul:
While I do not profess to completely comprehend slack, I have been assured by members of the Church that I do have it.

With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law. Ultimately the contributors are responsible for their content and we do not review the content once a project is taken on.

Most rejections of content come about because the content is too commercial, just personal, or relies on advertising.

Metadata and easy searching
by RyanMuldoon
iBiblio stands out as an excellent repository for a wide range of culturally valuable resources. As it and other sites grow in size, the importance of good searching and indexing becomes extremely relevant. Have you given any thought to how you might want to cope with this? Specifically, are there any metadata schemata that you are considering using? I would love to see iBiblio be used more like a content feed to research/cross-referencing applications.

Paul:
Interesting that you asked about this as this is an area that we've been working in for the past couple of years. Actually we go way back to pre-Web metadata to the Internet Anonymous FTP Archive (IAFA) files which were the model for the Linux Software Map (LSM). Thanks to Jonathan Magid for this innovation and for suggesting that we host Linux in the very beginning.

When we designed our contributor-maintained Collection Index, we designed it to create and display metadata that could be shared via the Open Archives Initiative (OAI). Please note that this metadata is at the collection level - not at the item level. Item level metadata is for future work. Also since you asked: Miles Efron and I will be presenting a paper at the Digital Resource in the Humanities conference in September on the Problem of Access in Contributor-Run Digital Libraries. Serena Fenton is co-author to this paper.

On the Linux Documentation Project front, we worked with several others to create the Open Source Metadata Framework (OMF).

The OMF aims to collect data about Open Source documentation, or metadata, that will be used to describe the documentation. The idea is that the OMF will act as a sophisticated card catalog type of system for the numerous Open Source documentation projects that exist. The OMF offers a number of advantages over standard card catalog type systems, however. Chief among these is the fact that the OMF has been designed from the ground up to be completely open, standards based, and sharable. We will accomplish this by using pre-defined standards (XML and the Dublin Core description for metadata) and allowing all metadata generated to be accessed by anyone that wants it. Because the metadata itself is to be stored in XML files, anyone should be able to use it.

OMF support is included in the Scrollkeeper project. Note that none of these metadata designs are overly complex. That is by design. The idea is to keep the metadata simple enough to be understood by the creator of the digital item or collection that it describes. If I could make one strong point about metadata design it is that simplicity is the key - and the hardest thing to pull off.

Trust metric and online publishing
by Creosote
I heard you talk at the Southern Presses conference last year about the use of trust metrics (like Slashdot's karma and Advogato's peer certification) as a possible alternative to the "top-down" means of filtering that scholarly and commercial publishers use, namely formal peer review and mass marketing, respectively. Are you more or less optimistic about the long-term viability of this model then you were then? (Especially in light of the powerful efforts to keep control of the gates we're seeing these days from Hollywood, the recording industry, and their political allies...)

Paul:
Beginning here I am speaking personally and not on behalf of ibiblio.org or any of its sponsors or supporters including but not limited to the University of North Carolina.

The Blog is one example of creator-empowerment that has gotten more attention since that talk and I think there will be plenty more examples to come. I still believe that people in constant communications will result in "Smart Mobs" (thank you, Howard Rheingold, for naming and noticing and writing on this). This is not just about music or movies or about one country or even one age group. While I don't think that we will completely replace our reliance, however reluctant, on Mickey Mouse, I do think that we are entering a time in which there are new opportunities for us to share information and to work together. The slew of misguided efforts by media and information cartels, especially the RIAA, which demonize their customers and clients, will make things tough but they also are signs that the old solutions are not working well and that newer, and I hope more inclusive and more open, solutions are on the horizon.

GeekPAC and "When Congress Attacks"
by lunenburg
I noticed that you are one of the founders of the American Open Technology Consortium and/or GeekPAC - the lobbying group that got a bit of fanfare a few months back when it was formed, but has been pretty quiet since then. With Congress launching seemingly daily attacks on our technological freedom in order to support the revenue models of a few huge businesses, the need for a voice in Washington is growing urgent. Is the AOTC/GeekPAC working to get our voices heard? Is there a need for an umbrella group to tie together various groups like GeekPAC, Public Knowledge, Digital Consumer, etc.?

Paul:
Yes, (again speaking only as Paul) I am an officer of the American Open Technology Consortium (AOTC). But for various complex reasons, I am not a member of GeekPAC. As you might have guessed, getting these projects going has been no simple matter. Jeff Gerhard has been doing a wonderful job of making sure the legal and procedural steps are properly taken. So far, what you are seeing is some very motivated but very busy people learning how to work together to get the projects off the ground. The good news is that folks like Jeff, Doc Searles and others on the boards are smart, dedicated and experienced people who can and will play well with others (including Public Knowledge and Digital Consumer and EFF). We hope to represent slightly different voices than those already represented. If you are reading this, you know who you are and we need your help.

About the umbrella group, I think that a summit conference (or at least a summit listserv) would make more sense. This kind of looser structure, often called an Action Committee or Organizing Committee, has been very successfully used by both ends of the political spectrum in the past half century.

Two words...
by Anonymous Coward
DRM? Palladium?

What's your take on these two technologies?

Are you afraid they'll ultimately destroy what you have been working for, for the past 10 years? If not, why?

Optional question: What about the copyright extension we have seen?

Another optional question: Linux... or BSD? =)

Paul:
Not Linux vs BSD, but Digital Rights Management and Microsoft's Palladium. DMR is the general term for the groups of solutions to the need for creators to be compensated for their work while allowing their audience to easily access those works. Or at least that would be ideally what DRM should do.

When DRM goes wrong, it tramples on the rights of the citizens to have access to information that they have legally purchased, want to criticize, parody, legally reuse or share.

When DRM goes wrong, it creates barriers to innovation and creativity. It biases access and reproduction of information to only certain technologies.

When DRM goes wrong, it creates and perpetrates closed markets and monopolies.

When DRM goes wrong, everyone suffers. It takes us back to the Stationers Guild, a response to the printing press. "The Stationers Guild obtained monopoly rights in the printing and probably distribution of all books, a monopoly codified by the Tudors in a licensing system aimed at censoring religious dissent" which lasted until the early 1700s.

When DRM goes wrong, it is called Palladium.

The good news is that Palladium is vaporware - so far.

What is your greatest success/failure?
by burgburgburg
Simple enough question in two parts:

Looking back on 10 years of doing this, what would classify as your greatest success, and your greatest failure?

Paul:
The simplest question is the hardest, of course. Luckily, you've narrowed the success/failure question to deal only with sunsite/metalab/ibiblio and not the past 10 years of my life.

One mark of great success is that we are still here hosting some of the original collections of information to be shared on the Net including the first 7/24 radio simulcast on the net, WXYC. We've been a part of many innovations and I, personally, have been able to work with some brilliant folks who often surprised themselves with what they had accomplished. We're also funded and we enjoy support from some wonderful and diverse faculties at UNC.

There is no question in my mind that the most significant decision that I made in those ten years was to listen to Jonathan Magid when he suggested that we become the US site for an operating system that didn't even work yet - Linux. If you are reading this far and are happy, you owe Jonathan. If you are unhappy, blame me.

In research, there is no such thing as failure. As I was explaining to our Interim Vice Chancellor, we are supposed to make mistakes. As Ms. Frizzle says, "Take chances, get messy and EXPLORE! Wahoo!".

Still, I do wish that we had found a way to use WAIS or another distributed search engine in a way that is still useful. There still seems to me to be something unfinished in that area. Killing gopher. That was more fun than Wack-a-mole.

And one final answer:

Slack.
by dsb3
You host a slew of subgenius content, so it must be asked ... do you have slack?

Paul:
While I do not profess to completely comprehend slack, I have been assured by members of the Church that I do have it.

Okay, here are answers from Paul Jones, director of ibiblio.org. You asked, and he responded -- and not always as seriously as you'd expect from someone who can ask us to call him "Professor Jones" or "Doctor Jones." But he's really "Just Paul," he says, "even in class." We hope a whole lot of you have a chance to meet Paul in person one day, because he's not only a warm and friendly guy, but one who has done a whole lot of good for Linux -- and for the Internet in general.

Paul:
Let me start out with a little overview of sunsite.unc.edu/metalab.unc.edu. Or better yet to point you to our annotated timeline. Then say that ibiblio.org began and has continued to be a way for the University of North Carolina (the original and still the best) to explore information sharing in the context of our missions of education, research and outreach. You folks using and contributing are the outreach part. In particular, we "acquire, discover, preserve, synthesize, and transmit knowledge" with all of your help.

We are a joint project of the School of Information and Library Science (there we are involved in digital archives and digital libraries), The School of Journalism and Mass Communication (there we are involved in electronic publishing and multimedia sharing), and the Vice Chancellor for Information Technology.

Except for one and occasionally two full time employees, our entire staff consists of students or in my case part time (as I have faculty responsibilities). So be nice to all of us, we're always learning. No matter what Robin said in the article introducing me, none of this would have happened without some very good people on staff and contributing content.

But that brings us to:

Question of Money
by too_bad
One of the things that people frequently ask about sites like ibiblio.org is "They are great. But how long will they be around?" Do you see this as a concern (esp. after the LWN announcement) and do you have any comments regarding this. Are there any good approaches you suggest (like augmenting free usership with voluntary subscriptions, etc) for such free sites in general?

Paul:
We have been very lucky, since our beginning, to have generous and understanding support from The University of North Carolina and from sponsors large and small including Sun, IBM, Red Hat, VA Linux^h^h^h^h^hSoftware, Mandrake, Cisco and others.

We also do get some research contracts and grants, but most importantly for us in the past two years has been a large gift from the founders of Red Hat and the Center for the Public Domain.

We have some top secret international funding sources as well. At the moment, we actually have a small endowment that if spent wisely should last several years. It is my hope that we will never have to charge the patrons of our digital archives.

BUT this brings me to my favorite question, which only got a rating of 4:

Donations?

Typical Questions
by suwain_2
I've downloaded my share of things, and find that the 3 Mbps cap on my cable modem is almost always my bottleneck. So my question is fairly simple (albeit broad) -- can you describe your setup a bit, in terms of bandwidth (both what you have for an Internet connection, and how much traffic you actually use), servers, storage (I'd venture to guess it's to the tune of several terabytes?), etc.

Paul:
We're on UNC's network. Our connections to the commodity and Internet2 networks are served by UNC's OC-48 network connection. We maintain a constant throughput of network traffic outbound in the 160-180Mbits/sec range.

Our current main servers were donated by IBM and serve content from a central fileserver with 2TB of disk attached. In our racks, we have approximately 5TB of space (with system disks, Sourceforge and an Internet2/Distributed Storage Initiative node). We do some load balancing between streaming services, web services, and large downloads like distros. On a typical day, we move over 1.5 terabytes of data off our servers. (Thanks to Fred Stutzman for much of this info.)

Backups
by Chris Pimlott
What's your backup strategy? I imagine it's hard to deal with both so much data as well as being under constant bombardment from clients around the world. How often is data archived? Have you had any major data loss incidents and, if so, how well were you able to deal with them?

Paul:
Like everyone else we rely on Archive.org, but seriously... (Fred answers this since he did the restore).

We run managed backups on UNC's enterprise storage facilities. We run them every night and have incremental backups for three months. UNC uses StorageTek machines and Tivoli Distributed Storage Manager for enterprise backups. We have had major data loss incidents, in which a raid card failed and lost the array's configuration. One of the disks in the array died simultaneously, we were unable to re-import the configuration to the new card, so we had to restore from backup, which took a number of days.

I, Paul, can only say that in the past things were much worse and we did have one famous meltdown in 1995 that was not pretty. Since then the UNC enterprise backup has been our friend - and for the most part disks and RAID arrays have been increasingly more reliable.

What's your biggest area?
by Otter
I know ibiblio (I still think of it as SunSite) as a) a repository of Unix software, especially useful for pre-Freshmeat apps and b) a mirror provider. "Free online publisher" wouldn't have made the list, but looking at your main page I see all sorts of things I didn't realize you hosted. Which ones get the most traffic?

Paul:
For sheer bytes, ISOs rule. But then it doesn't take too many downloads to get a lot of bytes for an ISO. Source-based distros like Gentoo have seen a lot of activity lately.

One of our most visited sites is also one of our oldest, Nicholas Pioch's WebMuseum (originally WebLouvre). An amusing reason may be that, as Nicolas writes:

"I've just found out that Microsoft Encarta Deluxe 2001 (the copy I just happened to find out and install) has direct links ('Web Links') from each artist's article to the webmuseum (on metalab.unc.edu at the time) and that's actually the only weblink provided in that 2001 edition."

Among other favorites are:

• The Linux Documention Project, which began on sunsite
• Documenting the American South
• Hong Kong Picture Archive
• Henriette's Herbal Homepage
• Hyperwar A hypertext history of the Second World War

What about content producers?
by Fluid Donkey
In general how supportive have you found the producers of such content to be of your services? Do many if any really believe that something like this will cause them to starve to death?

Paul:
First, they are all with us voluntarily and can leave any time, taking their stuff with them. That alone pretty much says that they believe in what we are helping them do.

I should say also that not all material is copyleft. But all of it is free to view, listen to and to reference. We are working with Creative Commons, which we also host, to develop a small but viable set of licenses for folks including our contributors who want to share their work on various terms (attribution, home or personal use, educational use, etc).

One important contributor, Roger McGuinn, has been making one folk song a month available for download since November 1995 on his Folk Den. He also sells CDs and performs concerts. He seems to be doing pretty well. Many contributors are scholars or students who understand the importance of sharing information.

Dave Farley, who does the wonderful Dr Fun, has a book contract with Plan 9, and we're looking forward to seeing what we've seen in electrons in print.

Relative importance of different material?
by kafka93
What is the center's view on the publishing of material that might be considered "offensive" or "dangerous", and does the center make subjective judgements upon the importance of one piece of intellectual property over another on the basis of 'artistic worth', 'decency', etc.? With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law. Ultimately the contributors are responsible for their content and we do not review the content once a project is taken on.

Most rejections of content come about because the content is too commercial, just personal, or relies on advertising.

What about content producers?
by Fluid Donkey
In general how supportive have you found the producers of such content to be of your services? Do many if any really believe that something like this will cause them to starve to death?

Paul:
First, they are all with us voluntarily and can leave any time, taking their stuff with them. That alone pretty much says that they believe in what we are helping them do.

I should say also that not all material is copyleft. But all of it is free to view, listen to and to reference. We are working with Creative Commons, which we also host, to develop a small but viable set of licenses for folks including our contributors who want to share their work on various terms (attribution, home or personal use, educational use, etc).

One important contributor, Roger McGuinn, has been making one folk song a month available for download since November 1995 on his Folk Den. He also sells CDs and performs concerts. He seems to be doing pretty well. Many contributors are scholars or students who understand the importance of sharing information.

Dave Farley, who does the wonderful Dr Fun, has a book contract with Plan 9, and we're looking forward to seeing what we've seen in electrons in print.

Relative importance of different material?
by kafka93
What is the center's view on the publishing of material that might be considered "offensive" or "dangerous", and does the center make subjective judgements upon the importance of one piece of intellectual property over another on the basis of 'artistic worth', 'decency', etc.? With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law. Ultimately the contributors are responsible for their content and we do not review the content once a project is taken on.

Most rejections of content come about because the content is too commercial, just personal, or relies on advertising.

Metadata and easy searching
by RyanMuldoon
iBiblio stands out as an excellent repository for a wide range of culturally valuable resources. As it and other sites grow in size, the importance of good searching and indexing becomes extremely relevant. Have you given any thought to how you might want to cope with this? Specifically, are there any metadata schemata that you are considering using? I would love to see iBiblio be used more like a content feed to research/cross-referencing applications.

Paul:
Interesting that you asked about this as this is an area that we've been working in for the past couple of years. Actually we go way back to pre-Web metadata to the Internet Anonymous FTP Archive (IAFA) files which were the model for the Linux Software Map (LSM). Thanks to Jonathan Magid for this innovation and for suggesting that we host Linux in the very beginning.

When we designed our contributor-maintained Collection Index, we designed it to create and display metadata that could be shared via the Open Archives Initiative (OAI). Please note that this metadata is at the collection level - not at the item level. Item level metadata is for future work. Also since you asked: Miles Efron and I will be presenting a paper at the Digital Resource in the Humanities conference in September on the Problem of Access in Contributor-Run Digital Libraries. Serena Fenton is co-author to this paper.

On the Linux Documentation Project front, we worked with several others to create the Open Source Metadata Framework (OMF).

The OMF aims to collect data about Open Source documentation, or metadata, that will be used to describe the documentation. The idea is that the OMF will act as a sophisticated card catalog type of system for the numerous Open Source documentation projects that exist. The OMF offers a number of advantages over standard card catalog type systems, however. Chief among these is the fact that the OMF has been designed from the ground up to be completely open, standards based, and sharable. We will accomplish this by using pre-defined standards (XML and the Dublin Core description for metadata) and allowing all metadata generated to be accessed by anyone that wants it. Because the metadata itself is to be stored in XML files, anyone should be able to use it.

OMF support is included in the Scrollkeeper project. Note that none of these metadata designs are overly complex. That is by design. The idea is to keep the metadata simple enough to be understood by the creator of the digital item or collection that it describes. If I could make one strong point about metadata design it is that simplicity is the key - and the hardest thing to pull off.

Trust metric and online publishing
by Creosote
I heard you talk at the Southern Presses conference last year about the use of trust metrics (like Slashdot's karma and Advogato's peer certification) as a possible alternative to the "top-down" means of filtering that scholarly and commercial publishers use, namely formal peer review and mass marketing, respectively. Are you more or less optimistic about the long-term viability of this model then you were then? (Especially in light of the powerful efforts to keep control of the gates we're seeing these days from Hollywood, the recording industry, and their political allies...)

Paul:
Beginning here I am speaking personally and not on behalf of ibiblio.org or any of its sponsors or supporters including but not limited to the University of North Carolina.

The Blog is one example of creator-empowerment that has gotten more attention since that talk and I think there will be plenty more examples to come. I still believe that people in constant communications will result in "Smart Mobs" (thank you, Howard Rheingold, for naming and noticing and writing on this). This is not just about music or movies or about one country or even one age group. While I don't think that we will completely replace our reliance, however reluctant, on Mickey Mouse, I do think that we are entering a time in which there are new opportunities for us to share information and to work together. The slew of misguided efforts by media and information cartels, especially the RIAA, which demonize their customers and clients, will make things tough but they also are signs that the old solutions are not working well and that newer, and I hope more inclusive and more open, solutions are on the horizon.

GeekPAC and "When Congress Attacks"
by lunenburg
I noticed that you are one of the founders of the American Open Technology Consortium and/or GeekPAC - the lobbying group that got a bit of fanfare a few months back when it was formed, but has been pretty quiet since then. With Congress launching seemingly daily attacks on our technological freedom in order to support the revenue models of a few huge businesses, the need for a voice in Washington is growing urgent. Is the AOTC/GeekPAC working to get our voices heard? Is there a need for an umbrella group to tie together various groups like GeekPAC, Public Knowledge, Digital Consumer, etc.?

Paul:
Yes, (again speaking only as Paul) I am an officer of the American Open Technology Consortium (AOTC). But for various complex reasons, I am not a member of GeekPAC. As you might have guessed, getting these projects going has been no simple matter. Jeff Gerhard has been doing a wonderful job of making sure the legal and procedural steps are properly taken. So far, what you are seeing is some very motivated but very busy people learning how to work together to get the projects off the ground. The good news is that folks like Jeff, Doc Searles and others on the boards are smart, dedicated and experienced people who can and will play well with others (including Public Knowledge and Digital Consumer and EFF). We hope to represent slightly different voices than those already represented. If you are reading this, you know who you are and we need your help.

About the umbrella group, I think that a summit conference (or at least a summit listserv) would make more sense. This kind of looser structure, often called an Action Committee or Organizing Committee, has been very successfully used by both ends of the political spectrum in the past half century.

Two words...
by Anonymous Coward
DRM? Palladium?

What's your take on these two technologies?

Are you afraid they'll ultimately destroy what you have been working for, for the past 10 years? If not, why?

Optional question: What about the copyright extension we have seen?

Another optional question: Linux... or BSD? =)

Paul:
Not Linux vs BSD, but Digital Rights Management and Microsoft's Palladium. DMR is the general term for the groups of solutions to the need for creators to be compensated for their work while allowing their audience to easily access those works. Or at least that would be ideally what DRM should do.

When DRM goes wrong, it tramples on the rights of the citizens to have access to information that they have legally purchased, want to criticize, parody, legally reuse or share.

When DRM goes wrong, it creates barriers to innovation and creativity. It biases access and reproduction of information to only certain technologies.

When DRM goes wrong, it creates and perpetrates closed markets and monopolies.

When DRM goes wrong, everyone suffers. It takes us back to the Stationers Guild, a response to the printing press. "The Stationers Guild obtained monopoly rights in the printing and probably distribution of all books, a monopoly codified by the Tudors in a licensing system aimed at censoring religious dissent" which lasted until the early 1700s.

When DRM goes wrong, it is called Palladium.

The good news is that Palladium is vaporware - so far.

What is your greatest success/failure?
by burgburgburg
Simple enough question in two parts:

Looking back on 10 years of doing this, what would classify as your greatest success, and your greatest failure?

Paul:
The simplest question is the hardest, of course. Luckily, you've narrowed the success/failure question to deal only with sunsite/metalab/ibiblio and not the past 10 years of my life.

One mark of great success is that we are still here hosting some of the original collections of information to be shared on the Net including the first 7/24 radio simulcast on the net, WXYC. We've been a part of many innovations and I, personally, have been able to work with some brilliant folks who often surprised themselves with what they had accomplished. We're also funded and we enjoy support from some wonderful and diverse faculties at UNC.

There is no question in my mind that the most significant decision that I made in those ten years was to listen to Jonathan Magid when he suggested that we become the US site for an operating system that didn't even work yet - Linux. If you are reading this far and are happy, you owe Jonathan. If you are unhappy, blame me.

In research, there is no such thing as failure. As I was explaining to our Interim Vice Chancellor, we are supposed to make mistakes. As Ms. Frizzle says, "Take chances, get messy and EXPLORE! Wahoo!".

Still, I do wish that we had found a way to use WAIS or another distributed search engine in a way that is still useful. There still seems to me to be something unfinished in that area. Killing gopher. That was more fun than Wack-a-mole.

And one final answer:

Slack.
by dsb3
You host a slew of subgenius content, so it must be asked ... do you have slack?

Paul:
While I do not profess to completely comprehend slack, I have been assured by members of the Church that I do have it.

Okay, here are answers from Paul Jones, director of ibiblio.org. You asked, and he responded -- and not always as seriously as you'd expect from someone who can ask us to call him "Professor Jones" or "Doctor Jones." But he's really "Just Paul," he says, "even in class." We hope a whole lot of you have a chance to meet Paul in person one day, because he's not only a warm and friendly guy, but one who has done a whole lot of good for Linux -- and for the Internet in general.

Paul:
Let me start out with a little overview of sunsite.unc.edu/metalab.unc.edu. Or better yet to point you to our annotated timeline. Then say that ibiblio.org began and has continued to be a way for the University of North Carolina (the original and still the best) to explore information sharing in the context of our missions of education, research and outreach. You folks using and contributing are the outreach part. In particular, we "acquire, discover, preserve, synthesize, and transmit knowledge" with all of your help.

We are a joint project of the School of Information and Library Science (there we are involved in digital archives and digital libraries), The School of Journalism and Mass Communication (there we are involved in electronic publishing and multimedia sharing), and the Vice Chancellor for Information Technology.

Except for one and occasionally two full time employees, our entire staff consists of students or in my case part time (as I have faculty responsibilities). So be nice to all of us, we're always learning. No matter what Robin said in the article introducing me, none of this would have happened without some very good people on staff and contributing content.

But that brings us to:

Question of Money
by too_bad
One of the things that people frequently ask about sites like ibiblio.org is "They are great. But how long will they be around?" Do you see this as a concern (esp. after the LWN announcement) and do you have any comments regarding this. Are there any good approaches you suggest (like augmenting free usership with voluntary subscriptions, etc) for such free sites in general?

Paul:
We have been very lucky, since our beginning, to have generous and understanding support from The University of North Carolina and from sponsors large and small including Sun, IBM, Red Hat, VA Linux^h^h^h^h^hSoftware, Mandrake, Cisco and others.

We also do get some research contracts and grants, but most importantly for us in the past two years has been a large gift from the founders of Red Hat and the Center for the Public Domain.

We have some top secret international funding sources as well. At the moment, we actually have a small endowment that if spent wisely should last several years. It is my hope that we will never have to charge the patrons of our digital archives.

BUT this brings me to my favorite question, which only got a rating of 4:

Donations?

Typical Questions
by suwain_2
I've downloaded my share of things, and find that the 3 Mbps cap on my cable modem is almost always my bottleneck. So my question is fairly simple (albeit broad) -- can you describe your setup a bit, in terms of bandwidth (both what you have for an Internet connection, and how much traffic you actually use), servers, storage (I'd venture to guess it's to the tune of several terabytes?), etc.

Paul:
We're on UNC's network. Our connections to the commodity and Internet2 networks are served by UNC's OC-48 network connection. We maintain a constant throughput of network traffic outbound in the 160-180Mbits/sec range.

Our current main servers were donated by IBM and serve content from a central fileserver with 2TB of disk attached. In our racks, we have approximately 5TB of space (with system disks, Sourceforge and an Internet2/Distributed Storage Initiative node). We do some load balancing between streaming services, web services, and large downloads like distros. On a typical day, we move over 1.5 terabytes of data off our servers. (Thanks to Fred Stutzman for much of this info.)

Backups
by Chris Pimlott
What's your backup strategy? I imagine it's hard to deal with both so much data as well as being under constant bombardment from clients around the world. How often is data archived? Have you had any major data loss incidents and, if so, how well were you able to deal with them?

Paul:
Like everyone else we rely on Archive.org, but seriously... (Fred answers this since he did the restore).

We run managed backups on UNC's enterprise storage facilities. We run them every night and have incremental backups for three months. UNC uses StorageTek machines and Tivoli Distributed Storage Manager for enterprise backups. We have had major data loss incidents, in which a raid card failed and lost the array's configuration. One of the disks in the array died simultaneously, we were unable to re-import the configuration to the new card, so we had to restore from backup, which took a number of days.

I, Paul, can only say that in the past things were much worse and we did have one famous meltdown in 1995 that was not pretty. Since then the UNC enterprise backup has been our friend - and for the most part disks and RAID arrays have been increasingly more reliable.

What's your biggest area?
by Otter
I know ibiblio (I still think of it as SunSite) as a) a repository of Unix software, especially useful for pre-Freshmeat apps and b) a mirror provider. "Free online publisher" wouldn't have made the list, but looking at your main page I see all sorts of things I didn't realize you hosted. Which ones get the most traffic?

Paul:
For sheer bytes, ISOs rule. But then it doesn't take too many downloads to get a lot of bytes for an ISO. Source-based distros like Gentoo have seen a lot of activity lately.

One of our most visited sites is also one of our oldest, Nicholas Pioch's WebMuseum (originally WebLouvre). An amusing reason may be that, as Nicolas writes:

"I've just found out that Microsoft Encarta Deluxe 2001 (the copy I just happened to find out and install) has direct links ('Web Links') from each artist's article to the webmuseum (on metalab.unc.edu at the time) and that's actually the only weblink provided in that 2001 edition."

What about content producers?
by Fluid Donkey
In general how supportive have you found the producers of such content to be of your services? Do many if any really believe that something like this will cause them to starve to death?

Paul:
First, they are all with us voluntarily and can leave any time, taking their stuff with them. That alone pretty much says that they believe in what we are helping them do.

I should say also that not all material is copyleft. But all of it is free to view, listen to and to reference. We are working with Creative Commons, which we also host, to develop a small but viable set of licenses for folks including our contributors who want to share their work on various terms (attribution, home or personal use, educational use, etc).

One important contributor, Roger McGuinn, has been making one folk song a month available for download since November 1995 on his Folk Den. He also sells CDs and performs concerts.

Relative importance of different material?
by kafka93
What is the center's view on the publishing of material that might be considered "offensive" or "dangerous", and does the center make subjective judgements upon the importance of one piece of intellectual property over another on the basis of 'artistic worth', 'decency', etc.? With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law.

UNC uses StorageTek machines and Tivoli Distributed Storage Manager for enterprise backups. We have had major data loss incidents, in which a raid card failed and lost the array's configuration. One of the disks in the array died simultaneously, we were unable to re-import the configuration to the new card, so we had to restore from backup, which took a number of days.

I, Paul, can only say that in the past things were much worse and we did have one famous meltdown in 1995 that was not pretty. Since then the UNC enterprise backup has been our friend - and for the most part disks and RAID arrays have been increasingly more reliable.

What's your biggest area?
by Otter
I know ibiblio (I still think of it as SunSite) as a) a repository of Unix software, especially useful for pre-Freshmeat apps and b) a mirror provider. "Free online publisher" wouldn't have made the list, but looking at your main page I see all sorts of things I didn't realize you hosted. Which ones get the most traffic?

Paul:
For sheer bytes, ISOs rule. But then it doesn't take too many downloads to get a lot of bytes for an ISO. Source-based distros like Gentoo have seen a lot of activity lately.

One of our most visited sites is also one of our oldest, Nicholas Pioch's WebMuseum (originally WebLouvre). An amusing reason may be that, as Nicolas writes:

"I've just found out that Microsoft Encarta Deluxe 2001 (the copy I just happened to find out and install) has direct links ('Web Links') from each artist's article to the webmuseum (on metalab.unc.edu at the time) and that's actually the only weblink provided in that 2001 edition."

Among other favorites are:

• The Linux Documention Project, which began on sunsite
• Documenting the American South
• Hong Kong Picture Archive
• Henriette's Herbal Homepage
• Hyperwar A hypertext history of the Second World War

What about content producers?
by Fluid Donkey
In general how supportive have you found the producers of such content to be of your services? Do many if any really believe that something like this will cause them to starve to death?

Paul:
First, they are all with us voluntarily and can leave any time, taking their stuff with them. That alone pretty much says that they believe in what we are helping them do.

I should say also that not all material is copyleft. But all of it is free to view, listen to and to reference. We are working with Creative Commons, which we also host, to develop a small but viable set of licenses for folks including our contributors who want to share their work on various terms (attribution, home or personal use, educational use, etc).

One important contributor, Roger McGuinn, has been making one folk song a month available for download since November 1995 on his Folk Den. He also sells CDs and performs concerts. He seems to be doing pretty well. Many contributors are scholars or students who understand the importance of sharing information.

Dave Farley, who does the wonderful Dr Fun, has a book contract with Plan 9, and we're looking forward to seeing what we've seen in electrons in print.

Relative importance of different material?
by kafka93
What is the center's view on the publishing of material that might be considered "offensive" or "dangerous", and does the center make subjective judgements upon the importance of one piece of intellectual property over another on the basis of 'artistic worth', 'decency', etc.? With only limited resources available to promote the archiving of data, is there the risk that important fringe documents may be left by the wayside, or ignored due to political/social concerns?

Paul:
Like non-digital archives and libraries, we have a Collection Policy. You'll note that we do not explicitly ban materials for content nor do we plan to. We do not maintain materials that are illegal, slanderous, libelous, or otherwise prohibited by law. Ultimately the contributors are responsible for their content and we do not review the content once a project is taken on.

Most rejections of content come about because the content is too commercial, just personal, or relies on advertising.

Metadata and easy searching
by RyanMuldoon
iBiblio stands out as an excellent repository for a wide range of culturally valuable resources. As it and other sites grow in size, the importance of good searching and indexing becomes extremely relevant. Have you given any thought to how you might want to cope with this? Specifically, are there any metadata schemata that you are considering using? I would love to see iBiblio be used more like a content feed to research/cross-referencing applications.

Paul:
Interesting that you asked about this as this is an area that we've been working in for the past couple of years. Actually we go way back to pre-Web metadata to the Internet Anonymous FTP Archive (IAFA) files which were the model for the Linux Software Map (LSM). Thanks to Jonathan Magid for this innovation and for suggesting that we host Linux in the very beginning.

When we designed our contributor-maintained Collection Index, we designed it to create and display metadata that could be shared via the Open Archives Initiative (OAI). Please note that this metadata is at the collection level - not at the item level. Item level metadata is for future work. Also since you asked: Miles Efron and I will be presenting a paper at the Digital Resource in the Humanities conference in September on the Problem of Access in Contributor-Run Digital Libraries. Serena Fenton is co-author to this paper.

On the Linux Documentation Project front, we worked with several others to create the Open Source Metadata Framework (OMF).

The OMF aims to collect data about Open Source documentation, or metadata, that will be used to describe the documentation. The idea is that the OMF will act as a sophisticated card catalog type of system for the numerous Open Source documentation projects that exist. The OMF offers a number of advantages over standard card catalog type systems, however. Chief among these is the fact that the OMF has been designed from the ground up to be completely open, standards based, and sharable. We will accomplish this by using pre-defined standards (XML and the Dublin Core description for metadata) and allowing all metadata generated to be accessed by anyone that wants it. Because the metadata itself is to be stored in XML files, anyone should be able to use it.

OMF support is included in the Scrollkeeper project. Note that none of these metadata designs are overly complex. That is by design. The idea is to keep the metadata simple enough to be understood by the creator of the digital item or collection that it describes. If I could make one strong point about metadata design it is that simplicity is the key - and the hardest thing to pull off.

Trust metric and online publishing
by Creosote
I heard you talk at the Southern Presses conference last year about the use of trust metrics (like Slashdot's karma and Advogato's peer certification) as a possible alternative to the "top-down" means of filtering that scholarly and commercial publishers use, namely formal peer review and mass marketing, respectively. Are you more or less optimistic about the long-term viability of this model then you were then? (Especially in light of the powerful efforts to keep control of the gates we're seeing these days from Hollywood, the recording industry, and their political allies...)

Paul:
Beginning here I am speaking personally and not on behalf of ibiblio.org or any of its sponsors or supporters including but not limited to the University of North Carolina.

The Blog is one example of creator-empowerment that has gotten more attention since that talk and I think there will be plenty more examples to come. I still believe that people in constant communications will result in "Smart Mobs" (thank you, Howard Rheingold, for naming and noticing and writing on this). This is not just about music or movies or about one country or even one age group. While I don't think that we will completely replace our reliance, however reluctant, on Mickey Mouse, I do think that we are entering a time in which there are new opportunities for us to share information and to work together. The slew of misguided efforts by media and information cartels, especially the RIAA, which demonize their customers and clients, will make things tough but they also are signs that the old solutions are not working well and that newer, and I hope more inclusive and more open, solutions are on the horizon.

GeekPAC and "When Congress Attacks"
by lunenburg
I noticed that you are one of the founders of the American Open Technology Consortium and/or GeekPAC - the lobbying group that got a bit of fanfare a few months back when it was formed, but has been pretty quiet since then. With Congress launching seemingly daily attacks on our technological freedom in order to support the revenue models of a few huge businesses, the need for a voice in Washington is growing urgent. Is the AOTC/GeekPAC working to get our voices heard? Is there a need for an umbrella group to tie together various groups like GeekPAC, Public Knowledge, Digital Consumer, etc.?

Paul:
Yes, (again speaking only as Paul) I am an officer of the American Open Technology Consortium (AOTC). But for various complex reasons, I am not a member of GeekPAC. As you might have guessed, getting these projects going has been no simple matter. Jeff Gerhard has been doing a wonderful job of making sure the legal and procedural steps are properly taken. So far, what you are seeing is some very motivated but very busy people learning how to work together to get the projects off the ground. The good news is that folks like Jeff, Doc Searles and others on the boards are smart, dedicated and experienced people who can and will play well with others (including Public Knowledge and Digital Consumer and EFF). We hope to represent slightly different voices than those already represented. If you are reading this, you know who you are and we need your help.

About the umbrella group, I think that a summit conference (or at least a summit listserv) would make more sense. This kind of looser structure, often called an Action Committee or Organizing Committee, has been very successfully used by both ends of the political spectrum in the past half century.

Two words...
by Anonymous Coward
DRM? Palladium?

What's your take on these two technologies?

Are you afraid they'll ultimately destroy what you have been working for, for the past 10 years? If not, why?

Optional question: What about the copyright extension we have seen?

Another optional question: Linux... or BSD? =)

Paul:
Not Linux vs BSD, but Digital Rights Management and Microsoft's Palladium. DMR is the general term for the groups of solutions to the need for creators to be compensated for their work while allowing their audience to easily access those works. Or at least that would be ideally what DRM should do.

When DRM goes wrong, it tramples on the rights of the citizens to have access to information that they have legally purchased, want to criticize, parody, legally reuse or share.

When DRM goes wrong, it creates barriers to innovation and creativity. It biases access and reproduction of information to only certain technologies.

When DRM goes wrong, it creates and perpetrates closed markets and monopolies.

When DRM goes wrong, everyone suffers. It takes us back to the Stationers Guild, a response to the printing press. "The Stationers Guild obtained monopoly rights in the printing and probably distribution of all books, a monopoly codified by the Tudors in a licensing system aimed at censoring religious dissent" which lasted until the early 1700s.

When DRM goes wrong, it is called Palladium.

The good news is that Palladium is vaporware - so far.

What is your greatest success/failure?
by burgburgburg
Simple enough question in two parts:

Looking back on 10 years of doing this, what would classify as your greatest success, and your greatest failure?

Paul:
The simplest question is the hardest, of course. Luckily, you've narrowed the success/failure question to deal only with sunsite/metalab/ibiblio and not the past 10 years of my life.

One mark of great success is that we are still here hosting some of the original collections of information to be shared on the Net including the first 7/24 radio simulcast on the net, WXYC. We've been a part of many innovations and I, personally, have been able to work with some brilliant folks who often surprised themselves with what they had accomplished. We're also funded and we enjoy support from some wonderful and diverse faculties at UNC.

There is no question in my mind that the most significant decision that I made in those ten years was to listen to Jonathan Magid when he suggested that we become the US site for an operating system that didn't even work yet - Linux. If you are reading this far and are happy, you owe Jonathan. If you are unhappy, blame me.

In research, there is no such thing as failure. As I was explaining to our Interim Vice Chancellor, we are supposed to make mistakes. As Ms. Frizzle says, "Take chances, get messy and EXPLORE! Wahoo!".

Still, I do wish that we had found a way to use WAIS or another distributed search engine in a way that is still useful. There still seems to me to be something unfinished in that area. Killing gopher. That was more fun than Wack-a-mole.

And one final answer:

Slack.
by dsb3
You host a slew of subgenius content, so it must be asked ... do you have slack?

Paul:
While I do not profess to completely comprehend slack, I have been assured by members of the Church that I do have it.

This week's Slashdot questions go to Paul Jones, director of ibiblio.org (formerly MetaLab, before that SunSITE) since it first went live in August, 1992. Ibiblio hosts the world's largest Linux archive (including the LDP), plenty of streamed and downloadable music, the world's longest-running Web cartoon (Dr. Fun), and thousands of texts on topics too numerous to list here. This is truly "the public's library and digital archive," 100% GPL, copyleft, and/or public domain, sponsored jointly by the Center for the Public Domain and UNC. Lots of people talk about free online publishing. Paul Jones just does it, day after day, year after year. Ask him whatever you want; we'll send 10 of the highest moderated questions to him and post his answers as soon as we get them back.

Leandro Dardini is desperately seeking Hinrich: "As consultant for a local provider, I have to present a solution for a big problem: tunnel IPX over IP to permit old application users to connect via Internet. After digging google, I found ipxtund, written by Hinrich Eilts in 1998. It works great even after 4 years, but I have a question to the author. The author vanished. After searching again in Google, I found the last clue of Hinrich in a post on 23 Jul 1999, then nothing. I don't want to think the worst, but, Hinrich Eilts, where are you?"

gunnk asks: "Here's the deal: I really, really, REALLY want to avoid having a Windows partition on my computer, but I have some nifty games that I still want to play (particularly Civ III). I own a copy of VMware, but Civ3 coughs up an error telling me I'm running a debugger and need to unload it when I try to start the game. All this seems to come up due to copy protection in games. Someone asked something like this over at WINE and was told to grab a copy of the exe without the protection via gamecopyworld. That didn't work for me either (didn't run). Anyone finding any reliable ways to run these games without a Windows partition?"

Russ Jones writes "As a student at the University of North Carolina at Chapel Hill, we have been struggling with finding ways to provide internet access to our growing off-campus students - currently, students have few to no options other than traditional, expensive, commercial providers. After feeling out large contracts through the University with major providers, it has become clear that they do not want to play ball with a public institution. Regardless, as a student I am still very interested in finding a solution to at least some of the woes. Students at Carolina are required to purchase laptops, many of which are wireless enabled. The University has put a lot of funding into wireless initiatives (but has only looked into using short-distance access points). Are there any long distance alternatives, that could possibly stretch a mile or more in radius? Any ideas on possible alternatives?"

Guylhem writes "After the problems the LDP had with Debian rules, it seems clear we need an organization which would for example sort documentation between free (as "libre" or "freedom") and non free. After some discussions with people from the GNU project and the FSF, we came to the conclusion no such project already existed. I am please to announce that I am now starting the GNU Writing Movement with help from the GNU project. We will provide links to existing free documents, with a possibility to rate the documentation quality. The project is not competing with existing documentation project such as the LDP or GDP. It will complement them, both by serving somewhat as a meta-project for free software documentation, to provide help to authors willing to replace their FAQ or HOWTO will a full Guide on a specific topic, and to develop brand-new book-length material on many topics. " If you can't find a home for your documentation at an existing documentation project, and you agree with the philosophy of the GNU project, we can help you. Volunteers are welcome for the first phase of the project - cataloging existing free software documentation, rating it, and determining TODO lists for what needs to be documented.

Slashback tonight with another assortment of corrections, amplifications, looks backward (and even looks forward to looks backward). In this last case, it looks like you may even get fed.

You mean we have to reprint all the invitations? Reader Ian Cowley wrote with a slight correction about the end of an era:

"Your article on slashdot.org about the billionth second of the epoch is sort of (but not entirely) flawed.

Yes, UNIX systems will report 1000000000 seconds at 01:46:40 on 9th September. Which of course means the 1 billionth number will be 01:46:39.

But, these systems do not account for leap seconds. According to TAI (international atomic time), the 1 billionth second since the beginning of January 1st 1970 will occur at 01:46:17 on 9th September 2001, as 22 leap seconds have been inserted since 1970 (the first was 1972, the last 1999).

So celebrations of the 1000000000th second should be at 01:46:17, whilst 01:46:40 can be reserved for celebrating 1000000000 displayed on UNIX system clocks."

Errr ... thanks. We'll just have to start at "Unix Day, Observed."

What price the capture and humiliation of virus spreaders? JayHerrick writes: "We have posted a small bit of JSP that reports the number of times our server has been queried for a 'default.ida' page. It's stylish, it's cool, and it'll probably get Pepsi all mad at us because we ripped the Code Red logo off one of the bottles." Equally stylish, despite the name, is a small tool named codeRedNeck, described by reader mindriot thus: "As CodeRed probes port 80 of a machine, CodeRedNeck first answers on that port and then goes silent, thus forcing the worm to wait until the connection times out." He advises: "Read the original idea by Tom Liston. Heise also has more on this."

Even More Auspicious dates. No matter which date you choose to mark it, Linus' little kernel-that-could is about to mark its tenth birthday. ikluft writes:

"The "Linux10" Linux 10th anniversary picnic and BBQ will be held on Saturday, August 25 from 11AM to 6PM at Sunnyvale Baylands Park in Sunnyvale, California. Details and directions can be found at Linux10.org. If you can attend, please use the RSVP form so the organizers know how much food and soft drinks to provide (only provided if you RSVP.)

Linux10 is being organized as a family event -- bring the kids. In support of that goal, it is also a no-media event. Linux and Open Source enthusiasts who work for the media may attend and participate while off-duty.

Linux10 will gladly link to other Linux 10th anniversary events. Let us know the URLs for those events."

Reader big_drew adds: "The event is free (food, softdrinks, cds -- sorry, no free beer, but byo is ok)" and says "If you can't make it out to CA, you can still get the t-shirt (profits will be used to fund the picnic)."

Anyone want to organize a picnic in the vicinity of Knoxville, TN? :) I can bring some pasta salad and watermelon.

Ten candles all around here, too. Simon Spero writes: "As noted in http://www.w3.org/History.html, today, August 6th, is the 10th anniversary of the first public release of the CERN Web Software."

rbruels writes: "They first made their appearance as clunky high-tech note pads for Captain Kirk (embedded sound warning) and his crew, but back here in the 21st century, the proliferation of the PDA has become a real phenomenon. This story on Unstrung gives a good insight into the evolution of these portable devices, and the factors that will influence their growth in the years to come. A good read. (As a side note, I have yet to purchase a PDA. /me hangs his head in shame.)" More importantly than where they've been though, is what's next for PDAs. What features would you trade the baby for?

Andrea Cabibbo writes: "Scientists at the University of North Carolina at Chapel Hill have successfully created a liquid form of DNA.

utoddl asks: "Now that Microsoft is dropping volume licensing for non-NT versions of Windows, will corporate types who are forced to 'upgrade' from their Win9x OSes be any more likely to look at alternatives to NT (say, Linux, for example) than they would be otherwise? Could it be that Microsoft's attempt to increase the NT revenue stream by forcing the hand of slow adopters cause some to adopt something else instead?" Ouch! This will cause hell for shops who have a large number of Win9x based clients. Is this a desperate move by Microsoft to increase revenues from one area that they are expecting to lose in another year?

ErikSev writes "I know there's already been one /. story about this, but The Register is running a few more that might be of interest regarding the whole scheme to put copy protection on hdds. First is the proposal, then Alan Cox and RMS' responses, and finally the IBM spin on the whole deal. This is definately something we need to be afraid of."
