An anonymous reader quotes a report from Ars Technica: A vicious species of tick originating from Eastern Asia has invaded the U.S. and is rapidly sweeping the Eastern Seaboard, state and federal officials warn. The tick, the Asian longhorned tick (or Haemaphysalis longicornis), has the potential to transmit an assortment of nasty diseases to humans, including an emerging virus that kills up to 30 percent of victims. So far, the tick hasn't been found carrying any diseases in the U.S. It currently poses the largest threat to livestock, pets, and wild animals; the ticks can attack en masse and drain young animals of blood so quickly that they die -- an execution method called exsanguination.

Key to the tick's explosive spread and bloody blitzes is that its invasive populations tend to reproduce asexually, that is, without mating. Females drop up to 2,000 eggs over the course of two or three weeks, quickly giving rise to a ravenous army of clones. In one U.S. population studied so far, experts encountered a massive swarm of the ticks in a single paddock, totaling well into the thousands. They speculated that the population might have a ratio of about one male to 400 females. Yesterday, August 7, Maryland became the eighth state to report the presence of the tick. It followed a similar announcement last Friday, August 3, from Pennsylvania. Other affected states include New York, Arkansas, North Carolina, Virginia, and West Virginia.

Memory modules using Intel's 3D XPoint technology are on their way, and researchers in North Carolina have already figured out how to make them better. New submitter mnemotronic writes: At the 45th ICSA (International Symposium on Computer Architecture), a group of researchers from North Carolina State University led by Prof. Yan Solihin proposed a method called lazy consistency to speedup write operations to 3d XPoint memory. XPoint, developed by Intel and Micron, is non-volatile, cheaper and denser than DRAM but requires more power and writing takes longer. The method proposed reduces write overhead times from 9% to 1% by incorporating a checksum to the cache memory system. The researchers were not able to verify their approach on actual XPoint memory, as those products only recently started sampling. They tested using simulations and DRAM and plan to verify when Intel's modules become more widely available.

Zothecula writes We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots".

ph4cr writes with news that a few researchers have discovered an alloy that allows them to print 3D structures from liquid metal at room temperature. From the article: "'It's difficult to create structures out of liquids, because liquids want to bead up. But we’ve found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at room temperature to form a "skin" that allows the liquid metal structures to retain their shapes,' says Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the work. ... One technique involves stacking droplets of liquid metal on top of each other, much like a stack of oranges at the supermarket. The droplets adhere to one another, but retain their shape – they do not merge into a single, larger droplet. ... Another technique injects liquid metal into a polymer template, so that the metal takes on a specific shape. The template is then dissolved, leaving the bare, liquid metal in the desired shape. The researchers also developed techniques for creating liquid metal wires, which retain their shape even when held perpendicular to the substrate." The paper is available online. There's also a video of the process in action, below the fold.

An anonymous reader writes "There's a persistent bias against older programmers in the software development industry, but do the claims against older developers' hold up? A new paper looks at reputation on StackOverflow, and finds that reputation grows as developers get older. Older developers know about a wider variety of technologies. All ages seem to be equally knowledgeable about most recent programming technologies. Two exceptions: older developers have the edge when it comes to iOS and Windows Phone."

hypnosec writes "By using liquid metal researchers have created wires that can stretch up to eight times their original length while retaining their conduction properties. Scientists over at North Carolina State University made the stretchable wires by filling in a tube made out of an extremely elastic polymer with gallium and an indium liquid metal alloy."

ShipLives writes "Researchers have tested Google's app verification service (included in Android 4.2 last month), and found that it performed very poorly at identifying malware in apps. Specifically, the app verification service identified only ~15% of known malware in testing — whereas existing third-party security apps identified between 51% and 100% of known malware in testing."

ShipLives writes "Mobile security researchers have identified an aspect of Android 4.0.4 (Ice Cream Sandwich) and earlier models that clickjacking rootkits could exploit. As part of an effort to identify potential weaknesses in smartphone platforms, the team was able to develop a proof-of-concept prototype rootkit that attacks the Android framework, rather than the underlying operating system kernel."

yahoi writes "Researchers at NC State are sharing their analysis and classification of Android malware samples under a new project that they hope will help shape a new way of fighting malware, learning from the lessons of the PC generation and its traditional anti-malware products. Xuxian Jiang, the mastermind behind the Android Malware Genome Project, says defenses against this malware today are hampered by the lack of efficient access to samples (PDF), as well as a limited understanding of the various malware families targeting the Android. The goal is to establish a better way of sharing malware samples and analysis, and developing better tools to fight it, he says."

samazon writes "North Carolina State University researcher Jag Kasichainula has developed a 'heat spreader' to cool electronics more efficiently using a copper-graphene composite, which is attached using an indium-graphene interface film. According to Kasichainula, the technique will cool 25% faster than pure copper and will cost less to produce than the copper plate heat spreaders currently used by most electronics (abstract). Better performance at a lower cost? Let's hope so."

Hugh Pickens writes writes "For decades, mystified scientists have chalked up Santa's power to the inexplicable wonder of magic, but North Carolina State University aerospace engineer Larry Silverberg, team leader on a first-of-its-kind visiting scholars program at Santa's Workshop-North Pole Labs (NPL), says that Santa is, in fact, a scientific genius and that Silverberg looks forward to Christmas each year, so he can ponder the remarkable accomplishments of one of the greatest pioneers in his field. 'Santa is not just a jolly old elf,' says Silverberg. 'He really has an understanding of engineering, technology, science that's far beyond our own.'

Then there's Santa's sleigh itself, an advanced aerodynamic structure equipped with laser sensors to find the optimal path, and covered by a nanostructured 'skin' that is porous and contains its own low-pressure system, which holds the air flowing around the airborne sled onto the body, reducing drag by as much as 90 percent. Finally there's Santa's greatest invention, the relativity cloud, that bends time and space to allow for his round-the-world Christmas journey and explains why Santa is so seldom seen. 'Relativity clouds are controllable domains – rips in time – that allow him months to deliver presents while only a few minutes pass on Earth. The presents are truly delivered in a wink of an eye.'"

An anonymous reader sends this quote from an article at Ars Technica: "Researchers at North Carolina State University have uncovered a variety of vulnerabilities in the standard configurations of popular Android smartphones from Motorola, HTC, and Samsung, finding that they don't properly protect privileged permissions from untrusted applications (PDF). In a paper just published by researchers Michael Grace, Yajin Zhou, Zhi Wang, and Xuxian Jiang, the four outlined how the vulnerabilities could be used by an untrusted application to send SMS messages, record conversations, or even wipe all user data from the handset without needing the user's permission. The researchers evaluated the security of eight phones: the HTC Legend, EVO 4G, and Wildfire S; the Motorola Droid and Droid X; the Samsung Epic 4G; and the Google Nexus One and Nexus S. While the reference implementations of Android used on Google's handsets had relatively minor security issues, the researchers were 'surprised to find out these stock phone images [on the devices tested] do not properly enforce [Android's] permission-based security model.' The team shared the results with Google and handset vendors, and have received confirmation of the vulnerabilities from Google and Motorola. However, the researchers have 'experienced major difficulties' in trying to report issues to HTC and Samsung."

Trailrunner7 writes "The Android platform seems to have become the playground of choice for attackers and malware authors looking to make a quick buck. The latest example is a premium-rate SMS Trojan that not only automatically sends costly SMS messages, but also prevents users' carriers from notifying them of the new charges. The new piece of malware, which is known as HippoSMS, has been found in unofficial Android app markets in China. This is just the latest in a series of similar incidents in which attackers and scammers have inserted either outright malicious apps or seemingly benign apps containing malware into app markets. Most of the attacks have targeted Android users, and several times Google has had to remove malicious apps from the official Android market."

ShipLives writes "Researchers have developed a new method that can predict MMORPG player behavior. The tool could be used by the game industry to develop new game content, or to help steer players to the parts of a game they will enjoy most. I don't think it should replace user feedback, but it's a pretty cool data-driven approach. Ideally, it could help developers make good decisions about new games/expansions."

mimd writes "A researcher at North Carolina State University has discovered yet another Android Browser exploit that affects the new Android 2.3 (Gingerbread) and previous versions. Slashdot recently covered a previous browser exploit that affected all versions of the Android Browser, but was patched in 2.3. Xuxian Jiang writes 'our finding here is that the patch contained in Android 2.3 is not an ultimate fix and can still be bypassed. We have a proof-of-concept exploit with a stock Nexus S phone and are able to successfully exploit the vulnerability to steal potentially personal information from the phone.' The exploit is capable of reading and writing files from an Android's sdcard or system partition as well as uploading user data over the internet."

schliz writes "NCSU researchers are attempting to address today's 'blind trust' of virtualization with new security techniques that 'guarantee' malware does not infect hypervisors.

A proof-of-concept prototype has been tested on BitVisor and Xen, in research that will be presented (PDF) at an IEEE conference today."

Dotnaught writes "A paper (PDF) to be presented later this month at the IEEE International Parallel and Distributed Processing Symposium in Atlanta describes a new approach to memory management that allows software applications to run up to 20% faster on multicore processors. Yan Solihin, associate professor of electrical and computer engineering at NCSU and co-author of the paper, says that using the technique is just a matter of linking to a library in a program that makes heavy use of memory allocation. The technique could be especially valuable for programs that are difficult to parallelize, such as word processors and Web browsers." Informationweek has a few more details from an interview with Solihin.

CWmike writes "Engineers from North Carolina State University have created a new fingernail-size chip that can hold 1 trillion bytes (a terabyte) of data. They said their nanostructured Ni-MgO system can store up to 20 high-definition DVDs or 250 million pages of text, 'far exceeding the storage capacities of today's computer memory systems.' Using the process of selective doping, in which an impurity is added to a material whose properties consequently change, the engineers worked at nanoscale and added metal nickel to magnesium oxide, a ceramic. The resulting material contained clusters of nickel atoms no bigger than 10 square nanometers — a pinhead has a diameter of 1 million nanometers. The discovery represents a 90% size reduction compared with today's techniques, and an advancement that could boost computer storage capacity. 'Instead of making a chip that stores 20 gigabytes, you have one that can handle one terabyte, or 50 times more data,' said the team's leader, Jagdish 'Jay' Narayan, director of the National Science Foundation Center for Advanced Materials and Smart Structures at the university."

g8orade points out two recent articles in The Economist about the rise of cloud computing. The first discusses how software-as-a-service has come to pervade online interactions. "Irving Wladawsky-Berger, a technology visionary at IBM, compares cloud computing to the Cambrian explosion some 500m years ago when the rate of evolution sped up, in part because the cell had been perfected and standardised, allowing evolution to build more complex organisms." The next article examines how the cloud will force a "trade-off between sovereignty and efficiency." Reader pjones contributes news that the Virtual Computer Lab will be supplementing more traditional computer labs at North Carolina State University, and adds, "NCSU's Virtual Computing Lab and IBM are offering the VCL code as a software 'appliance' for use in schools to link to the program. Downloads are available at ibiblio at UNC-Chapel Hill. The VCL also is partnering with Apache.org to make the software available and to allow further community participation in future development."

According to scientists from North Carolina State University and the University of Georgia, on that day, a predicted global urban population of 3,303,992,253 exceeded that of 3,303,866,404 rural people. In the US, the tipping point from a majority rural to a majority urban population came early in the late 1910s."

Roland Piquepaille writes "If you don't believe that Santa Claus can deliver presents to millions of homes in a single night, Larry Silverberg, professor of mechanical and aerospace engineering at North Carolina State University (NCSU), explains that Santa's society of elves has an understanding of physics and engineering that exceeds our own. In fact, Santa Claus and his crew really can deliver presents in one night because of their advanced knowledge of electromagnetic waves, the space/time continuum, nanotechnology, genetic engineering and computer science. For example, he doesn't carry presents. He uses a nano-toymaker to fabricate toys grown atom by atom inside the children's homes. Very entertaining reading...

Bansuki writes "The New York Times has an article about the role of the modding communities in the games industry. It's a decent overview of the current state of modding though it focuses heavily on Epic Games and the Unreal engine. They spotlight the Unreal University program (an Unreal sponsored event giving classes to potential modders) and Red Orchestra (a highly ambitious mod of the Unreal Warfare engine). The article also mentions machinima as a type of mod with artistic potential and gives due credit to Id Software and Bioware for their work in making engines available to the community. But here's a glaring omission: Half-life and its wildly successful mods. Odd."

Slashback with news on ATI drivers for non-ATI branded cards, the viewer-led movement to save Farscape, wearable computing from MIT, text-to-facial-expression software, and more. Read on for the details

Maybe customer service isn't dead. On November 28th, we posted a report that OEM cards using ATI chips had trouble with the official drivers from ATI. Terry Makedon (Senior Product Manager, Software for ATI Technologies) writes "Last week we posted a set of unified Linux drivers. These drivers were only loading up on 'Built by ATI' cards. Through our various feedback mechanisms we have determined that there is a large community of 'Powered by ATI' Linux users that did not benefit from our Linux drivers. At this point we are happy to announce an update to our Linux driver (ver. 2.5.1) which will work on both 'Powered by' and 'Built by.' ATI's driver and software strategy is firmly based on responsiveness and we greatly appreciate the feedback our Linux users have provided. Please use http://apps.ati.com/linuxDfeedback/ for a direct feedback line to ATI.

Thanks again for the feedback."

But what if we put the show into this Interdimensional Fungubulon, and then jumped through this here "wormhole"? xagon7 writes "David Kemper, the producer/writer of Farscape, mentioned that it would be theoretically and legally possible for a group to set up a non-profit organization for fans to donate money to, in order to finance an episode and make Farscape all that much tastier to Sci-Fi for the 5th season. They have done just that. They have $200,000 worth of pledges and only need $800,000 total....I hope this gets Slashdotted. Read the story here and you can pledge here."

You're getting less happy to see me? man_of_mr_e writes "Check out MIThril, the next generation research platform for context aware wearable computing. It's been about 18 months since this was last talked about here on Slashdot, and it's kind of cool to see how far the technology has come since then. For those that aren't aware of what it is, it's essentially a project to prototype human wearable computers, complete with schematics, pictures, and a cvs repository for software. Now you too can be like that guy in the IBM commercials trading stock while feeding the pigeons."

Flattening the slope to entry. Catskul writes "You don't need the libwine hack, mentioned in the previous news entry. Just follow the New QT Howto, download the codecs and start MPlayer."

Don't look at me in that tone of voice! 1010011010 writes "On Nov. 26, you ran a story on SpeechView, 'software that translates the voice on the other side of the line into a three dimensional animated face on the computer.' The North Carolina State University Department of Computer Science's 'Voice IO Group' is also working on that problem. Their software looks like it might be better. Read about it here.

Victory, or a reprieve? A non moose cow writes "Just noticed that a couple of my favorite "Killed by the RIAA" webcast stations are back... like Soma-FM and Monkey Radio (get the streams at Shoutcast).

In a highly insightful comment, user Kjella explained to me that I had been naive to think that First Sale would continue to exist in the world of DRM. (Of which I had pondered the ramifications here.) So Slashdot, where does the First Sale doctrine stand? Are libraries throughout the nation in jeopardy? Will they no longer carry digital media? Can a corporation, without any form of legal safeguard, really control whom I can sell my stuff to? It's enough to make you shudder."

kevinvee asks: "I am trying to find a suitable wireless web camera for broadcasting video streams from various sites around the university where I work, including buildings currently under construction which can be far from both network and electrical outlets. Besides the x10 packages, however, my search is coming up rather empty. Things we have to consider are the maximum distance from transmitter to receiver; power source, and if battery-powered, the average battery life; video quality; additional necessary hardware and software; outdoor/indoor capabilities; and weather resistance. I'm sure there are also other things to consider which we haven't thought of yet. Has anyone else tackled similar projects? What hardware did you attempt to use and what experiences did you have with it?"

ChetPan asks: "I'm doing some development for a couple of student-run sites at NC State University. We want to make dynamic portal-like customizable pages, but aren't really sure what to use to output the actual HTML, since the main concern here is performance. We have most of our code in Perl modules and we're wondering about the main (heavy traffic) pages. I don't know much about embperl or eperl and how they compare to regular mod_perl under Apache. Are there other embedded Perl solutions? Would we get a performance boost by using PHP? Unfortunately I haven't seen much neutral comparison of the different embedded types on the Web. I would especially appreciate seeing some benchmarks and/or statistics on the topic."

It would be nice to be able to query a database by product type (CPU, RAM) or brand (INTEL, AMD, Corsair) and be able to get graphs of each of their products and a graph of their respective prices over time. It could be helpful for determining when price drops will occur or for analyzing how new product releases affect pricing and would just be generally neat. Does anything like this exist already?"

A few weeks ago you asked the multi-talented Chris McKinstry questions, about the telescope projects he's involved with (ESO's Very Large Telescope -- VLT -- and the OverWhelmingly Large telescope -- OWL), about his project to synthesize AI by collecting a database of answers to questions common and obscure, and about the possibilities of discovering extraterrestrial life. Read what he has to say on everything from humans leaving the solar system to telescopes staying here on Earth. [Updated 5 Aug by t:] Chris notes for the record: "The opinions expressed are my own and not necessarily the opinions of the European Southern Observatory."

1) GAC
by Dungeon Dweller

I have an active interest in artificial intelligence. I study it as part of my major, and hope to do research in it in the future. As a young man coming up in the world, I am hoping to enter into research eventually, am entering into research at my university (WVU).

Your project reminds me of several projects/theories that have been discussed before. In the psychological debate, your system depends entirely upon nurture, it would seem. I like that kind of system and research. I do have a few questions.

1. What separates this from other projects in the field?
2. Where did you draw your inspiration for this project?
3. What kind of support staff do you recommend to an individual who has never led research before, but would like to? (I ask this of many of my professors who conduct research)
4. Where are you getting the bulk of your input for this project?
5. What do you hope to learn from this project?
6. At what time will you consider this project a success?

I know that I posed a lot of questions, but several could be answered in combination, I just didn't want to ask 2 questions at the same time.

Chris McKinstry:

Question 1-1:

There are three primary features of the MindPixel Digital Mind Modeling Project (also known by GAC -- for Generic Artificial Consciousness -- which is public interface to the project) that distinguish it from other large scale knowledge projects such as CYC.

1. The first phase is a completely public, internet based effort. All the data it will be collecting will come from average people, with no specific training in AI or psychology. It is like seti@home in many respects, except that we're not after your CPU's cycles, but rather your humanness. We're actually seeking to extract the entire content of an average person's mind bit by literal bit from millions of different internet users. We're not trying to write the algorithm for consciousness, but rather create the world's most rigorous fitness test (a Dawkinsian continuous variable) and get it into the hands of researchers who will attempt to make systems that will learn or evolve into consciousness by feeding back against this fitness test. Not only will we be collecting consensus fact, but also consensus emotion. (When the project is fully operational, in addition to collecting information about each MindPixel's truth or falsity, we will also collect emotional data based on Mehrabian's PAD model of emotion.)
2. The second phase of the project involves releasing the data collected to the scientific community and providing those researchers with some funds (generated by advertising to the people supplying the data) to conduct their research. As a side note, Jeff Elman's page contrains information about recurrent neural networks that are very good at processing just the kind of data that this project will collect and distribute. Specifically his 1990 article, Finding Structure in Time (PDF) is one of the most important neural network papers ever written; it strongly influenced me.
3. Finally, the project is a meritocracy. People will gain voting rights that will give them a say in every aspect of how the project is run, from data collection and use to the distribution of data and research funds, based entirely on the amount of data they have contributed to the project. The more work you do, the stronger your voice becomes.

Question 1-2:

My primary inspiration for the project comes from observation: I observed that computers are stupid and know nothing of human existence. I concluded a very long time ago that either we had to write a "magic" program that was able to go out in the world and learn like a human child, or we just had to sit down and type in ALL the data. When I was studying psychology in the late 80's I wanted to begin to gnaw the bullet and start getting people to type in ALL the data. It was my plan then to get people to enter data as part of an intro psych course, or get the university to allow me ask people for data when they logged on to the university's computer system. I was never able to get permission for either and the idea sat on the shelf until I downloaded my first copy of NCSA's Mosaic in 1994. I saw in following my first hyperlink, a different path.

I decided to collect my data via the internet. But, the problem was, that I needed to think of a standard format for the data; some way of representing human knowledge that an average person could learn quickly. That idea didn't come to me until I was preparing an entry for the 1995 Loebner Prize. Jackie, my program, was a stimulus response creature. You would ask her a full text question, and she scan her database for a canned full text response. My idea for the Loebner competition was to have her talk to a lot of people a get a lot of canned responses (at the time I was consulting for a large insurance company and brought Jackie to work everyday where she could talk to my colleagues) As well, I stored the responses in a number of different ways: phonetically using soundex, again with all the words in each stimulus sorted alphabetically, and also with a primitive concept token system. So, if there was no direct match, she would look for a phonetic match or sorted or conceptual match. Essentially I was breaking down each stimulus and standardizing it like a Fourier transform breaks down a waveform.

Then suddenly Hugh Loebner changed the rules. No longer was passing a text based Turing Test good enough for him. Now he would only award his prize if the system passed a full audio/video Inquisition. I hit the roof! Hell, there were tens of thousands of people on the planet that couldn't pass that kind of test! Anyone blind or deaf are just two obvious examples. I withdrew Jackie in a loud protest, stating that intelligence didn't depend on the bandwidth of the communication channel; intelligence could be communicated with one bit! If you locked a person in a box I could detect them with a series of yes/no questions and nothing more. And there all of a sudden, I had my answer (and a quick paper - The Minimum Intelligent Signal Test - An Objective Turing Test in Canadian Artificial Intelligence, issue 41.) There was a minimum intelligent signal, and it was just one bit. I would store my model of the human mind in binary propositions. I would make a digital model of the mind.

I realized within minutes that a giant database of these propositions could be used to train a neural net to mimic a conscious, thinking, feeling human being! I thought, maybe I'm missing something obvious. So, I emailed Marvin Minsky and asked him if he thought it would be possible to train a neural network into something resembling human using a database of binary propositions. He replied quickly saying "Yes, it is possible, but the training corpus would have to be enormous." The moment I finished reading that email, I knew I would spend the rest of my life building and validating the most enormous corpus I could.

Question 1-3:

Support staff! I recommend using the entire planet as support staff! Seriously, don't even dream about it. Almost every researcher I know works on their own or with a handful of collaborators. When you're a big cheese you might get a student or two, but other than that you'll get nothing more than shared use of a departmental secretary. You'll definitely be writing all your own code for a very long time.

Question 1-4:

I can't tell you that yet because at the time I wrote this, the project was not yet online (should be now though.) What I can tell you is that in 1995 I did try to collect this same data, using a web based form that sent an email back to me. I managed to collect some 450,000 items. This time, I expect to collect more and higher quality data and I expect it to come from a wide cross section of the internet public. I should also note MindPixels will be collected in multiple languages, which opens up the future prospect of mapping the sampled human languages to each other concept by concept. It will be very interesting to see exactly how an artificial consciousness trained in English differs at the conceptual level from one trained in say, Spanish.

Question 1-5:

I hope to learn what the human conceptual network looks like. I hope that in a few years I will be able to access a map of all the concepts in the head of an average person or to have learned why I can't.

Question 1-6:

I will consider the project a complete success when the cover of Science announces that for the first time in history there exists an artificial system that has passed a scientifically strong form of the Turing Test known as the Minimum Intelligent Signal Test.

2) How do you guys do it?
by pc486

With exptremely high magnification, how in heck do you keep the telescope still enough to take photos?

The slightest movement ought to mean millions of miles so thoes pesky little earthquakes should be a problem. Not to mention how you guys move the telescope accurately?

Chris: You're quite right about the system being very sensitive; if I walk on the azimuth platform of a VLT telescope while we're observing, I will destroy the observation. For normal tracking we use a software system called Tpoint written by a well known telescope genius named Pat Wallace (Pat has a wonderful and detailed article about telescope pointing that anyone seriously interested in telescope pointing should read); the same system is in use on telescopes all over the world. Basically what we do is build a pointing model for each of our telescopes. This involves pointing each telescope to a number of different points uniformly covering the sky. At each sample point, we observe a guide star and record how it moves from the center of the field over about one minute of tracking time. After we have collected enough data, we build a computer model of the telescope's tracking error. Then we basically run the model backwards into the telescope control system and thus apply corrections that try to cancel out the tracking errors of the telescope. This of course can't correct for any unusual vibrations, we rely on normal guide star tracking and hydraulic isolation of the telescope for that. And baring a large earthquake, Tpoint, automatic guide star corrections and the isolation work pretty well (In the event of a large earthquake, there are giant airbags that inflate to protect the mirror from damage.)

3) How can we help?
by Mignon

You probably know about SETI At Home, which lets people volunteer spare CPU time to processing radio-telescope data, in a (so far vain) attempt to find extra-terrestrial intelligence. Is there a similar way that we can help process some of the data that you gather?

As a simple example, one could compute the differences between a sequence of pictures of the same portion of the sky, looking for anomalies like giant asterioids on their way to wiping us all out.

Chris: seti@home is one of the most impressive demonstrations of how the world of science has changed. There are now over 2 million average people working together for a common scientific goal. I just wish they sold advertising to raise funds for other worthy (meritocratically determined) projects. It really bugs me that my Pentium III 450 which has done over 7000 hours of seti@home processing since last June, hasn't shown me a single science supporting ad. What a waste!

Now as for your idea of doing the same thing in optical wavelengths, I think in it there is a great deal of merit. There are a whole pile on new survey telescopes coming online soon that will be useful for just what you proposed. And if you read ahead to my answer to question 11, you'll see I do think it is a problem we have to pay attention to. (As well, I know of at least two virtual telescope projects; the NRC's National Virtual Telescope. See NVO White Paper (PDF) and ESO's ASTROVIRTEL which seek to allow data mining of previously collected telescope data.

In general, I think the future will see a lot more distributed processing projects doing useful science. The question remains whether or not it is more cost effective to build supercomputers for critical projects or harness the CPU's of private citizens, and I think the answer will need to be determined on a case by case basis. As well, there will be some projects (my own for example) where the CPU cycles are incidental; where what we want to harvest is not your electricity and capital equipment, but actually your humanity.

4) Division between Science and Spirituality
by ParticleGirl

I am continuously frustrated that people's general perception seems to be that science and art, spirituality, and so forth are divided by an uncrossable schism. People feel the need to pit science against spirituality; logic against intuition. It is a rare thing that people accept the idea that these are different ways of approaching the same reality. As a dreamer and artist as well as a respected scientist, what do you say to people who doubt that scientists can be spiritual and artistic people?

Chris: Science for me at least, is concerned with the external, the measurable; while art is concerned with the internal and immeasurable. Every scientist knows measurement can only go so far; that nature at its most fundamental is immeasurable. Unfortunately many scientists turn away from what they can't measure (and conversely, many artists turn from measurement) instead of finding some way, any way to express it. It is this turning away or fear of the immeasurable (or many artist's converse fear of reduction to measurement) that creates doubt; that separates science from art. The scientist can learn that one does not become any less of a scientist for attempting to express the inexpressible or attempting to measure the immeasurable, just as the artist can learn that because we are neurons and our neurons atoms, doesn't mean we are any less human.

5) CCD or what?
by paRcat

What kind of imaging does a telescope of this scale use? Is it an OWLCCD or something else? What kind of resolution? And how far away would an object need to be before the resolution becomes a shortcoming?

Chris: I actually can't answer this question. I am only aware of one discussion regarding instrumentation for the OWL and I haven't read it yet. See FROM ISAAC TO GOLIATH, OR BETTER NOT!? INFRARED INSTRUMENTATION CONCEPTS FOR 100M CLASS TELESCOPES (PDF) on the OWL project page.

6) Yeah, they're big ...
by viper21

But what do you do with them?

What kind of work do the telescopes at your facility generally do? Do local astronomers get to come in and do research or are the scopes reserved for some large project?

Chris: There is a very wide spectrum of observing programs for the VTL; from the study of comets in our solar system to the detection and measurement of objects on the edge of the observable universe. The VTL operates in two primary modes: visitor and service. In visitor mode, scientists actually travel to Chile and execute their observing program interactively with the support of operations personnel like myself who know the telescope and control system intimately and staff astronomers that know the instruments and science. Visitor mode is best utilized when the program contains interactive components, for example when what the observer does next depends on the results of what he has just completed. In service mode, observers don't travel to Chile but instead submit observing programs that don't have a large interactive component. Service programs are executed by staff astronomers and the data is automatically returned to the observer upon completion. Service mode is much like the old batch mode of mainframe computers. In both service and visitor modes, the programs that get time are determined by an observing program committee made up of scientists from all over the world based on scientific merit. And yes, a portion of the time (I believe it is 10%) automatically goes to Chilean astronomers in exchange for Chile's donation of the land for the project.

7) How parellelizable?
by Omnifarious

How parallelizable is the problem of micro-adjusting small portions of a large deformable mirror to correct for atmospheric distortion?

I remember a Scientific American article stating that you'd have to devote a top-of-the-line Cray to continuously recalculate the deformations needed given data from the guide star, or laser simulated guide star. If this problem is highly parallelizable, you may be able to get away with _much_ cheaper hardware.

I'm sure the idea has occured to you, but I want to know what your thoughts are on it.

Chris: My experience with deformable mirrors is entirely practical and I'm really not qualified to comment on the theory behind them. However, speaking from a practical standpoint, the VLT's 450 force actuators (150 per operating telescope) are each activated about 1000 times per night, night after night almost without error (7 non-critical electronic failures up to May of this year). I see no obvious reason why it shouldn't scale smoothly to 130 or 150 meters with current computer technology. And we certainly don't have any supercomputers doing the deformation calculations.

8) Why single-mirror?
by jd

I could have been mis-reading the article, but it seemed to me as though the idea was to build a single-mirror system. On the other hand, in radio astronomy, and in the insect world, arrays are considered the norm. Is there some advantage that a single mirror gives that cannot be duplicated using multiple smaller mirrors? (Simpler optics is an obvious one, paradoxically. :) Or is this (at least in part) NerdTrek III: The Search for Sponsors, where a record-setting single telescope is going to get more interest than a comparable array?

(A supplementary question, to go along with this. Let's say, for the sake of argument, that optical arrays are practical. Do you see any possibility of optical astronomers adopting the same line as radio astronomers, in trying to build an effective 1Km+ optical telescope, using an array?)

Chris: Actually, it isn't a single mirror. It is "filled aperture" telescope. The aperture is filled with many smaller mirrors, just like Keck. And as for optical arrays (interferometers), the VLT (called VLTI in this mode) will be the first real large scale test of such a system. But that stage of the project is still a few years away. In short, we'll have to wait and see how effective it is before we even consider giant optical interferometers.

9) funding
by jmayes

What's the biggest hurdle to hop over in getting funding for projects like OWL? And how did you pull it off?

Chris: The biggest hurdle for getting funding for projects like OWL, is getting funding for construction! Construction of OWL hasn't been funded, so nothing has really been pulled off, yet. But, if the public really wants projects like this to go ahead, then they need to be active about it. If you're in Europe, write your representatives and mention OWL by name and direct them to the OWL project page. If you're not in Europe, urge your representatives to find some way to participate in this project or projects like it.

10) Terrestrial Optical Telescopes
by pb

What are the benefits of having an Earth-bound, optical telescope? Or rather, what can a larger optical telescope find better from Earth that we can't already find on other wavelengths and from other venues (i.e. The Hubble)?

If there are no advantages here, is it more cost-effective, or what?

Chris: What you should actually ask is what advantage does a space based telescope have over a ground based telescope? The only thing you gain from being in space for an optical telescope is better image quality due to lack of atmospheric turbulence. By for every other measure (maintenance, support, materials, etc.) being in space is much, much more expensive and limited. Which is why the Hubble and it's 2.4 meter primary cost a number of times more than the projected cost of of the 100 meter OWL. Recent advances in computer technology (adaptive and active optics) have greatly reduced the advantage that being in space provides at optical wavelengths. For some non-optical telescopes (x-ray, IR, gamma ray) there will always be an advantage to being in orbit.

11) might as well ask it now..
by Blue Lang

I noticed in your 'fave books' section that you have the blind watchmaker, et al.

so, with an eye towards dawkins' views on evolution, what's your personal take on the probability (not the possibility) of humans locating extraterrestrial life without going outside the solar system?

Chris: Actually I'm quite pessimistic about the prospects of us locating ETL, AND independently about leaving the solar system. My main reason for this is that I doubt our civilization can last long enough. Not that I think we're going to self-destruct, but rather I think that nature is going to do it for us. It is my opinion that it is much more PROBABLE that we are driven into or close to extinction by an asteroid collision, than it is we will detect ETL or travel outside the solar system. This is one of the major reasons I strongly support construction of self-supporting Lunar and Martian colonies (and sky survey telescopes!) I just don't like us having all our eggs in the one basket called Earth. Having said all that, if we survive, I am confident we will eventually detect ETL, and that we will leave the solar system.

Earl Shannon writes, "With the new release of Sendmail I was looking over Sendmail.net and came across this essay called It's the User, Stupid. Author Mike Kuniavsky states a very important question if Linux wants to make inroads on the desktop as an open source solution. How can the open source development model obtain the necessary user feedback to development interfaces that the user will intuitively able to use?"

pb writes "Freshmeat has an excellent editorial about geek chicks. A lot of free software projects these days could really use that woman's touch. "
