Re:Bzzzt. Wrong.Linux and FreeBSD are not a lot better, but they are somwhat better. If any of these OS's had the share of Windows, trust me we would be seeing exploit after exploit just like Windows. Probably not mail worms and such, but something.
Morons, your train is leaving.
What, you say that like you expect every OS to ship with its pants pulled down to its ankles and bent over ready to take it without a firewall. Does 2k3 server ship with its firewall on by default yet (after 6 major OSes not counting OSRs?)? MacOSX does.
My friend brought his xp laptop over one day for some LAN gaming. He plugged it in to the LAN and it told him there were updates to install. I asked him when the last time he updated, and when he told me it had never been updated, I told him to turn on the firewall. He got to the network configuration box and was about 2 clicks away when the system told him it was shutting down. Doh!
So we've got Windows, and it shipping with a large number of services that are useless to nearly every user (such as the ms-blaster port, the spam-messenger port, and so on...) MacOSX client comes with... well, not much at all. I don't even think it runs apache out of the box.
And that remote root exploit? Its in the DHCP client's system configuration module. Meaning that 1) the attacker would have to be the DHCP server. 2) The system would have to have been configured to DHCP for an address. And 3) the system would have to be configured to fetch its configuration from the DHCP server, which isn't on by default, and would pretty much only be used in a corporate environment.
As for mail-transmitted worms/trojans/viruses, they'll certainly be around for the popular platform, but lets take a look at how they behave in windows. In fact, we'll use the w32.novarg.a@mm virus. According to that site, the third thing it does is
- %System%/taskmon.exe (If a copy of taskmon.exe exists in the %System%, it is overwritten and replaced by this copy of the worm.)
Whoa, there! Allowing USERS to overwrite SYSTEM FILES! -10 points! What about access levels? NT4 had it, and 2k and XP finally give it to the end users. Too bad that there are so many applications that require Administrator account privileges that most users effectively run as Administrator (if not actually use the Administrator account full time). Now of course, you can use various policy control tools and registry inspectors to determine what exactly the program is trying to access and granting specifically that access level to that program, but from what I've seen of Real Professional (ie not paper MCSE) Windows Administrators, its a long and thankless job that is repeated every new version of a program, for program after program from insert-nearly-any-game-here to your scanner. Now, get your mother to do that when she wants to use the scanner, or your 12 year old little brother who wants to play the latest Grand Theft Helicopter 14.
Oh and 5 words: "Don't click on any links"
I think the windows camp should worry more about the termites, cockroaches, and toxic mold infesting their own houses before calling the exterminator in on the ant in the Mac house.

Re:"Middleware" and "Enterprise"If "enterprise" and "middleware" are really real concepts and useful words, then how the hell did you spend 4 paragraphs and leave us with absolutely no information about what they are ?
I mean, come on. Read your own post. An enterprise (which is called that because it might not commercial -- i.e., "enterprising" . . . whiskey tango foxtrot ?) is something that uses middleware. Middleware is something that is used by an organization bigger than you guys have seen (i.e., an enterprise). There is a single word of information in there: "glue".
I am reminded of the sentence from William H. Whyte's "The Organization Man":
This book is about the organization man. If the term is vague, it is because I can think of no other way to describe the people I am talking about. They are not the workers, nor are they the white-collar people in the usual, clerk sense of the word. These people only work for The Organization. The ones I am talking about belong to it as well. They are the ones of our middle class who have left home, spiritually as well as physically, to take the vows of organization life, and it is they who are the mind and soul of our great self-perpetuating institutions. Only a few are top managers or ever will be. In a system that makes such hazy terminology as "junior executive" psychologically necessary, they are of the staff as much as the line, and most are destined to live poised in a middle area that still awaits a satisfactory euphemism.
The "satisfactory euphemism" that the world settled on, of course, was "Middle Management." It's an euphemism because the truth would be to call them "parasites, who once infesting a company can be got rid of only by bankruptcy." "Middleware" is a similarly an euphemism -- it's an euphemism for pointless spending done merely to increase the bureaucratic karma of a "Middle Manager."

Re:BSD vs LinuxHowever copyleft requires that any contributions must be GPL (and place a number of burdens on the creator that may or may not be unreasonable depending on context.)
The alternative is to turn to other products without protections to rip-off. I'd say the GPL was ensuring 1) the community's welfare and 2) resistance against permanent forking (I've mentioned elsewhere that forking by nature is a good thing for software evolution and longevity, but permanent forking and subsequent closure of code is a bad thing for the community).
Whoah nelly! This is such a whopping misconception of the current state of copyright law. The natural state of any work in the United States is ownership by the creator for a limited time as established by congress. Copyright registration is a technical formality.
Without registration, copyright is not proveable. For all practical purposes the work belongs in the public domain as it is often near impossible to prove in court who did what and when (of course there's the old postal trick). Actually, what you may be referring to by "current state" are the recent copyright extensioning and strengthening laws. These are aberrations that fly against the intent and original laws as defined by the founding fathers. The key problem here is that the approaches taken to overturn these laws have failed due to incorrect tactics with the current Supreme Court makeup. These new unjust laws will eventually be limited, but this will take some time. Disney will not continue to benefit from the works of Grimm and Anderson while others are unable to benefit from the works of Disney.

Re:pressure
One thing that requires very close to atmospheric pressure is hard drives. The heads float above the platter utilizing the bernouli principle. If the pressure too high, the heads get pulled down onto the platter (bad). If the pressure is too low, the heads don't get sucked down close enough, and data can't be read or written with any reliability.
For reference, look at the environmental specifications of any hard drive to see what pressures (often expressed in altitude above sea level) can operate under.
I work on a balloon based scientific experiment (specifically BLAST ) where the atmosphere is about 1/100th the pressure down here (altitude about 125,000 feet above sea level). We fly several computers onboard, and many are in pressure vessels soley to keep the hard drives happy. (We use some flash drives, but when our flights can easily be 2 weeks long and we produce about 11.5 Gbytes/day of binary data, we need a decent amount of storage). -

Good news for the Internet, bad news for Google
Business experts at the Wharton School are now predicting the ultimate demise of Google. According to them, once the SCO intellectual property lawsuit kicks into high gear, one of their main targets will be Google. Google, as you may already know, is one of the largest users of GNU/Linux, with some 10,000 seperate machines, all running the Linux operating system. Once SCO is successful with their lawsuit, Google will most likely be forced to declare banruptcy and shut down their services because of the expenses with trial costs, lawyers and of course Linux licensing fees. It will be a sad day indeed, since everyone I know uses and loves Google. But it is good to see a new player in the search engine game that looks like it can fill the gap left by Google.

Unison is great
I use Unison as a synchronization/backup tool for computers running Linux, Solaris, MacOSX, and WinXP. It's GPL, but written in OCAML, so will probably build on any platform that OCAML is available for. It works wonderfully. It can be configured to keep X number of backup copies of files as well. I like that my backups are just files in the file system and so don't require any fancy/special software to access them.

Re:Protocols of Zion
Although unquestionably a forgery, the Protocols of the Elders of Zion is taken seriously by more than a few cranks. It is widely circulated in the Arab world where it is used to stir up hatred of Jews. According to the Egyptian newspaper al-Usbu', the new Alexandria Library, a showpiece with substantial international support, put an Arabic translation of the Protocols of the Elders of Zion on display in the same case as the Torah, claiming that it is a central work of Jewish thought. After much criticism, they have now removed it. This posting on Language Log contains details and links. Similarly, Palestinian Authority Educational Television has repeatedly broadcast "educational" programs about the Protocols in which it is treated as real. The most recent instance of this was on December 28th. Palestine Media Watch issued this report, which includes an English-language transcript.
Before someone starts a flame war, this is not a statement about the situation in Iraq, Israel, Islam, Al-Qaeda or any other issue.

So why not use what you have already
Then you don't have to syncronize.
If you haven't already installed SSH on a machine in both locations, do so.
Follow the "Setting up Samba over SSH Tunnel mini-HOWTO" by Mark Williamson . Then you can use the server on each side to share out the files on the other side and not even change anything about how your users do anything. It's very simple to set up. It's 3 steps on each side plus adding it into a log in script or mapping on the individual machines. So you should be ready in 5 minutes.
If you still want to syncronize, there are tons of tools to do that including Unison.

term limits of copyrights
Too bad that statement is at best misleading and at worst entirely false... note the "over the 20 years" part--the Founding Fathers never intended copyrights to last as long as they do now; it was supposed to be a limited grant, limited as in less than 30 years (and even that, only after an extension, for which the original copyright holder would still have to be alive).
Thomas Jefferson himself said the term of copyrights, though he disagreed on copyrights at all, should be only 14 years later saying 19 years which should be within the writer's or in the case of patents the inventor's lifetyme. Thomas Jefferson's copyright term (fwd) features some letters between Jefferson and James Madison on copyrights. -
Re:that's pretty cool
Actually, not very many anthropologists these days do much linguistic work. That's partly because linguistics has developed as a separate field and partly because cultural anthropology was largely taken over by Postmodernists, as a result of which it has nearly died. Most research on "exotic" languages these days is done either by linguists or by missionaries (who want to translate the New Testament).
I am a linguist and have done extensive fieldwork, mostly on Carrier, the native language of a large region of northern British Columbia. (I also hack a little. Once upon a time I wrote the head-final shell mentioned in Charles Dodgson's comment.) Software is increasingly used for this kind of work, but for the most part it is not the sort of NLP software provided on the Morphix-NLP CD. A lot of that software is useful primarily if you've got a large corpus to work with, and it often presupposes that some basic resources exist, such as a lexicon, or at least a wordlist with part of speech information. For many languages even basic resources such as a lexicon don't exist or aren't available in electronic form, and when you're dealing with really small languages, there aren't any ready-made corpora, such as news text. If you want a text corpus, you've got to make it yourself, usually by recording people telling stories or whatever, and transcribing it. This is an important part of fieldwork, but its incredibly slow and tedious.
There are some tools designed specifically for this kind of linguistic research. One is Transcriber, a tool that assists a human being in transcribing audio recordings. One of the older tools is Shoebox a dictionary database program for field linguists, originally written to run under DOS.
Some of us have used Unix tools to extract and process information, e.g. grep to do regular expression searches. Ken Church at Bell Labs used to give a tutorial "Unix for Poets" on how to use Unix tools for linguistics. Here is his handout. For example, I've produced dictionaries of several dialects of Carrier using scripts written mostly in AWK plus the usual Unix tools, controlled by elaborate Makefiles. Some of us also use emacs a lot, not only as an editor but for doing searches. If you're interested in what kinds of software are of interest to linguists, you might check out the Computational Resources for Linguistic Research page.
It is worth mentioning that spread of the internet has made available a lot of useful material for linguistic research. There are now quite a few languages for which you can obtain a good chunk of text (say at least 100K words), and often you can find parallel text (that is, the language you're interested in plus a translation into English or another language that is useful to you). But this works mostly for relatively big languages, that is, say, languages with a million or more speakers. There are around 340 such languages, depending on how you count, about 2% of the world's oral languages.
One topic that concerns some of us is how software and other technology can speed up the process of documenting dying languages. Languages are rapidly become extinct - some experts estimate that as many as 90% of the languages currently spoken will be extinct in 100 years. [Computer languages may be proliferating at the same rate.:)] The late Ken Hale had seven languages die on him. If we don't find a way to speed up the documentation, or slow down the rate of extinction, most of those languages are going to die without very much being known about them.

Re:Rsync Protocol Was a Bad Idea
You might want to try Unison. It's basically a bidirectional rsync. It's GPL, but it does a great job. Much more reliable (when run over ssh, at least) than rsync and less of a hassle to train users how to get their files synchronized. I even have it working successfully in an all-Windows environment, including setting file ownership right (rsync did not do that for me when run as a daemon; SYSTEM owned all the files).

Re:Modern poetry requires more skill
I personally love ambiguity and freeform expression. I feel more comfortable with loose or no structure than with the strict metric and rhyming as in the poem by Frost you quote. Rhyming, particularly, is a real turn-off. A rhyming poem just doesn't breath.
Then I think what you feel would most comfortable with is prose. Seriously, though, there is a difference between ambiguity and airy nothingness; I maintain that modern poetry is characterized by the latter.
It's fine not to like rhyme. Frost obviously wrote those kinds of poems too. But unlike you, most other people do, and rhyme has been proven to connect with more people when done properly. Many poets have cast it off in the name of vanguardism, but the fact is good rhyming requires more effort than they care to expend. I agree that rhyming can help make a poem truly horrible, but this is because of the author's usage, not because of the practice of rhyming itself. Things like rhyme and metre are choices the poet makes; often his or her talent, subject matter and form are not well matched. If you could say this was true of Poe's or Frost's poems, that is one thing; to say that you don't like them because they rhyme is another.
"I would say that it is much harder to write/compose in a new form than just conforming to an existing form."
It is harder to do so and still bring inspiration to the common man. It is not hard to come up with new forms. It is hard to come up with new good forms. By and large the new forms that modern writers/composers have produced have been uninteresting at best, and are commonly aimed at fellow artists, not at normal people. Is it still art? Yes. Does it resonate with human nature? Will it survive the passage of time? No and probably not.

Re:Paper Electronics (for many things anyhow)Some of da Vinci's works may be lost to time.
The best estimate is that at least 75% of Leonardo's writings have been destroyed or lost since his lifetime. Most of the surviving codices are actually rebindings of his work which have been salvaged from elsewhere.
Then there is the problem that Leonardo hardly ever finished anything - he loved procrastinating work, so its hard to know if some works attributed to his pupils are actually overpaintings of Leonardo's work. he hardly ever signed anything, so a good number of paintings (and some sculptures) are suspected of being Leonardo's work, but it can't be proven.
And he kept experimenting - most famously in the case of The Last Supper in Milan. Leonardo wanted to paint with oils for their intense colouration, but did not want to use the traditional fresco technique of applying paint to wet plaster (Leonardo rarely worked for a long period of time - so the plaster would have dried before he completed the work).
So he invented an oil-based paint that could be applied to dried plaster. And it looked magnificent - contemporaries were in awe of the work - for a few years, but Leonardo's formulation did not bind to the plaster and the paint began to crumble from the plaster. The painting was then restored a number of times - quite crudely, which made a big difference to the work.
So if you are in Milan, go and see The Last Supper - it is a work of extraordinary beauty and power (and size), but it is a faint shadow of the original.
Leonardo also lost a lot of work thanks to his choice of patrons, most notably Ludovico Sforza, tyrant of Milan between 1480 and 1499. Ludovico hired Leonardo ostensibly to create a massive 8m high statue of a horse to commemorate Frederico Sforza, the dynasty's founder.
Well Leonardo being Leonardo, he didn't work terribly quickly and got side-tracked, spending much of his time producing the majority of his known paintings, designing fortifications for Milan, a giant crossbow and starting his obsession with geology.
In 1499, the French invaded Lombardy to settle their claim for the dukedom of Milan. Sforza lost the battle and fled - Leonardo took his opportunity to leave as well.
What he didn't take was the full-sized model of his horse. The clay model was destroyed by Gascon bowmen and reduced to rubble. In recent years, an American team have created a pair of monumental bronze horses inspired by the original. One is in Michigan, the other in Milan - I saw the latter one this summer - and in a word - WOW!
And just think, this is Leonardo da Vinci we are talking about, what has been lost from less-well-known artists? What about the collected works of the Library of Alexandria, the libraries of the Caliphate of Baghdad, Rome...?
Best wishes,
Mike. -
What the Founding Fathers though of copywrites
At least one Founding Father thought long copyrights were bad for the public, Thomas Jefferson. Based on an acturial calculation he proposed a term of 19 years to James Madison:
"The question Whether one generation of men has a right to bind another seems never to have been started on this [i.e., the European side -- Jefferson was writing from France] or our [American] side of the water... that no such obligation can be so transmitted I think very capable of proof. -- I set out on this ground, which I suppose to be self evident, that the earth belongs in usufruct to the living; that the dead have neither powers nor rights over it... A generation coming in and going out entire... would have a right on the first year of their self-dominion to contract a debt for 33 years, in the 10th for 24, in the 20th for 14, in the 30th for 4, whereas generations, changing daily by daily deaths and births, have one constant term, beginning at the date of their contract, and ending when a majority of those of full age at that date shall be dead. The length of that term may be estimated from the tables of mortality. Take, for instance, the tables of M. de Buffon... [according to which] half of those of 21 years [of age] and upwards living at any one instant of time will be dead in 18 years 8 months, or say 19 years as the nearest integral number. Then 19 years is the term beyond which neither the representatives of a nation, nor even the whole nation itself assembled, can validly extend a debt... This principle that the earth belongs to the living, and not to the dead, is of very extensive application... Turn this subject in your mind, my dear Sir... Your station in the councils of our country gives you an opportunity for producing it to public consideration... Establish the principle... in the new law to be passed for protecting copyrights and new inventions, by securing the exclusive right for 19 instead of 14 years."
Thomas Jefferson's copyright term (fwd)According the site above using actuarial tables from 1992 a Jeffersonian calculation would put the copyright term at 30-35 years, copyrights last more than twice that.

Re:Great Computer Science Papers & /. readersdon't expect him to give away the details that you would expect in a CS class
Let me quibble with you a bit.
There are no details to "give away". The knowledge isn't a secret.
I'm reminded of Robert Heinlein's book Starman Jones, where guilds, using Intellectual Property laws, had made all scientific and technical knowledge proprietary (much as guilds did in the Middle Ages).
Fortunately, in our world, we are moving away from that model. Scientific and technical knowledge is available to anyone with the tenacity and aptitude to learn it.
Certainly, all the knowledge to be learned in an introductory Computer Science course is available -- free -- on the web. For other disciplines, there's still the cost of $100 textbooks -- but more and more free alternatives are becoming available.- The Wikipedia project has spun off the Wikibooks, the free textbook project.
- MIT offers the OpenCourseWare initiative
- the venerable Project Gutenberg offers e-texts of public domain books
- The University of Pennsylvania complements Gutenberg with the Online Books Page
- and numerous other authors, universities, and organizations are jumping on the bandwagon
What's lacking is not the knowledge, or the software; what's lacking are tutors able to explain the tough bits, smooth the rough bits, and challenge their students to make the knowledge their own. Somebody to demonstrate adding a node to a linked list to the puzzled; someone to review the basic math for those of us (like me) who got a bit intimidated by Big O notation. that's the next problem, and the problem I want to address.
But the knowledge is a click away -- and no Sphinx is guarding any "secrets". -
Re:CVS, eh?
More good news: Perforce is free-as-in-beer for use in developing open source projects.
That sounded good, so I read their Open Source FAQ. After seeing the following ...
The End User License Agreement for Open Source Software Development requires that Perforce Software be granted read-only access to the Perforce server. What do I need to do to comply?
We will assume, unless otherwise notified, that we will be able to access your server at the server's licensed IP address, port 1666, using the Perforce user name "anonymous". When this is not true, you should include information for contacting your server when you fill out the license agreement.
... I immediately decided to stick with Unison.
While I embrace Open Source, I really don't feel comfortable with anyone at Perforce being able to "browse" through my home directory. Some of my software projects are open source, however my personal life and the contents of my home directory are not. -

Re:Why just home?The basic problem with versioning in the file system is deciding when to commit.
I use Unison for this, and it works great. A commit happens whenever I choose to run Unison. I'm a human. Unlike a computer, I understand what I'm doing and why. I know when I'm done working on something, and when I'm ready to synchronize my files.From the article:
- I get three major benefits from keeping my whole home directory in CVS: home directory replication, history and distributed backups.
I get all these benefits from Unison. Admittedly, the history only gives me snapshots at two different times (time 1=now, time 2=last time I committed), but that's always been good enough for me. Deleted the wrong file? No problem -- get it back from the other machine.Unison is also cool because, unlike CVS, it (a) is easy to set up and maintain, (b) is quick and easy to run, and (c) works just as easily with binary files as with text files.
-
unison is probably a better solution
My recommendation: use the Unison file synchronizer to keep multiple copies of your home directory in sync.
It's not quite the same thing as CVS, but that's probably a good thing. Most importantly, it won't give you versioning. On the other hand, it is symmetric (meaning, none of the copies are distinguished) and it is much less hassle to use. Also, you can define custom merge methods to automate merging of things like mailboxes. Unison is great for keeping a home directory (or portions of it) in sync between different desktops, and between desktops and laptops.
Note that for live backups, rsync is probably still the best choice because you want something unidirectional. -
Look at Unison

Been meaning to do someting like this with unison
Though not real time like a true RAID, I think what you're really after is something like rsync, as many other posters have mentioned. When this came up in an earlier story I found a like to Unison, which seems to be better for my needs at least.

Re:Geeks with political powerUmm, no. Jefferson was generally opposed to any form of monopoly. He even questioned the cost-benefit tradeoff of the "limited" monopolies we call Copyrights and Patents. An interesting discussion, with very interesting quotes is available here. .
I especially like the following Jefferson quote:
I like the declaration of rights as far as it goes, but I should have been for going further. For instance, the following alterations and additons would have pleased me... Article 9. Monopolies may be allowed to persons for their own productions in literature, and their own inventions in the arts, for a term not exceeding ___ years, but for no longer term, and for no other purpose.
The point being that said monopoly (conflating the concepts of Patent and Copyright) is a) of recognizable value in encouraging invention, whether literary or otherwise and b) dangerous enough for the limitation to be spelled out specifically in the Constitution. This would have rendered moot the "extension" shell game that the Copyright system continues to be run under. -
Re:A Modest Proposal
That, and "A Modest Proposal" is the de-facto title for a sarcastic proposal. Hey! Freshman english wasn't so useless after all!
;o) The original "A Modest Proposal" was written by Jonathan Swift in 1791. It includes (but is not limited to!) the suggestion to eat babies to solve poverty in Ireland."...and I believe no gentleman would repine to give ten shillings for the carcass of a good fat child, which, as I have said, will make four dishes of excellent nutritive meat..."

Project Gutenberg Australia has more recent works
Incidentally, there is a Project Gutenberg Australia which has quite a few works online which are still under copyright in the United States but not in Australia. Those seeking works more recent than 1923 or so might find it worthwhile taking a look there.
Keep in mind that if you don't reside in Australia you would be committing copyright infringement if you were to download anything from that site that is still under copyright in your country of residence.
Go to their site to see what they have, or use the invaluable U. Penn online books page to search for them. -
Re:Not Just Edison, Not Just CopyrightActually, the patent holders did file lawsuits, hundreds of them, against Ford vehicle owners. There was a huge public backlash; the lawsuit ended on something of a technicality; and Ford continues to exist where the other brands do not.
The biggest difference between now and then that I can see is that the RIAA is in bed with the news media. Who owns CNN? The same company that owns Warner Records. Who owns ABC? Disney. Who owns CBS? Viacom. All RIAA members. You'd never know there was a public outcry, because the public gets its information about this from RIAA members.
I know this sounds like conspiracy theory, but I honestly don't see how any major news outlet could be trusted to cover this objectively.

Re:Funny
Well, it doesn't seem people are really searching for a solution, or they'd be working to implement Capability Systems to replace the crappy ACL systems we have today, that provably and significantly reduce many of today's security problems.

Here's what I did
many years ago actually: I went to yard sales, flea markets, and public library book sales. $20 USD goes a long ways in those places. I also inherited most of my family's book collection, dating to the 1940's for college textbooks. I also went to places like the Online Books page, Project Gutenberg, and BlackMask Online to round out my collection of world favorites and classics. Librarians love me, btw...

Re:A Real RIAA Weak Point
Your argument is crap. If you had been paying any attention to the stories for the entire past year, you'd know the RIAA will file a complaint about any file which has a filename containing any words in a artist's name or a song name. I could have the right to download, upload, and burn the file on a disk then crap on it. I could even own the copyright to that file. Yet the RIAA would still file a complaint. They don't care. They want to stop the flow of information on the internet no matter if they own the rights to that information or not.
So you are saying no one has the right to distribute files which have words such as "Christina", "Madonna" (Whoa! I didn't know the RIAA owned an inn!) or "love"? There are many other words which would be banned too. In fact, probably every word in your post, so if you don't want to "infringe" on "copyrights", you will have to stop posting on Slashdot and everywhere else on the internet.

Man Purse... ok, you can stop laughing now...I'm telling you, it's a geat idea. I'm currently looking into getting some sort of bag to carry around with me most of the time. Call it a "man purse", "man bag", messenger bag, briefcase, satchel, whatever... I just want to keep my stuff in it.
Some things I've come across:
- Timbuk2: Supposedly top quality custom made bike messenger bags that come in four sizes (S,M,L,XL). They have a newer Shortcut bag that looks particularly interesting. Certainly not cheap.
- Manhattan Portage: These seem a little too hip and trendy for me, but they are certainly popular with the NYC crowd... especially the Model 1414 and various DJ bags. Not horribly priced, but not cheap.
- Maxpedition: I don't know much about this place. There are some people that recommend their Thermite Versipacks.
- e-Holster: Heh. No.
- SCOTTeVEST: Some people actually say these are cool. But it doesn't meet my design criteria of not wanting to wear a vest/jacket/etc all the time. What about summer?!
- Kelty supposedly has some smaller bags that people have used as well.
BTW, if anyone else has a bag that they are currently using, please share some info!

Exosquad?Anybody see those powersuits and think EXOSQUAD!????? I loved that show, saw every episode...and heard a rumor that they were making a live action movie out of it. Based on what we've seen in this trailer, I think they could make some pretty bitchin e-frames.
God I wish they'd pick up that license.....or if not that....perhaps the Battletech license. That's a license that's just DYING for the uber-hollywood-effects type thing seen in the Matrix. The mechs would look super realistic, and the battle scenes would be insane and I know every geek on the planet would go see it at least once.

Re:this change is not bad? wtf's wrong with you?Before you pontificate and try to talk down to someone you should check your facts.
Take a look at a map of the Canadian Artic. See all those islands up there (including Ellesmere island which is featured in the article)?
Covered with glacial ice.
See Greenland right beside it?
Covered with glacial ice.From here: The [Northwest] Passage itself runs through the Arctic Islands of Canada some 500 miles north of the Arctic Circle, only 1,200 miles from the North Pole. The 900-mile east-west water route runs from Baffin Island to the Beaufort Sea through a field of thousands of icebergs, and thence into the Pacific through the Bering Strait, which separates Siberia from Alaska.
So, your point, numb nuts?
Oh, and from USA Today: the Arctic's ice is floating in the ocean. If it melted, it wouldn't raise sea level although it would have other effects on the world's climate.
So, if you're going to attack other people for not checking their facts, you should at least cite a couple of references rather than pulling BS out of your ass.

It has been 14 years since two little-known electrochemists announced what sounded like the biggest physics breakthrough since Enrico Fermi produced a nuclear chain reaction on a squash court in Chicago. Using a tabletop setup, Stanley Pons and Martin Fleischmann, of the University of Utah, said they had induced deuterium nuclei to fuse inside metal electrodes, producing measurable quantities of heat. That was the opening bell for one of the craziest periods in science. Cold fusion, if real, promised to solve the world's energy problems forever. Scientists around the world dropped what they were doing to try to replicate the astounding claim. Full story
Astronomers using NASA's Hubble Space Telescope have discovered three of the faintest and smallest objects ever detected beyond Neptune. Each lump of ice and rock is roughly the size of Philadelphia and orbits just beyond Neptune and Pluto, where they may have rested since the formation of the solar system 4.5 billion years ago. The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks, or "planetesimals," from the solar system's creation. The results of the search were announced by a group led by Gary Bernstein of the University of Pennsylvania at a meeting of NASA's Division of Planetary Sciences in Monterey, Calif. Full article

Re:Is Stanford Eng Dept even Accredited?
After reading this, I thought "wait a minute..I just graduated from UPenn's SEAS (School of Engineering & Applied Sciences) with a BSE in CSE..it must be accredited"
...it turns out, however, that we are accredited in a bunch of engineering fields, but not computer science.
I don't know how I missed that. Doesn't seem to matter too much in the industry as far as I know...people are still getting the jobs -
