Bob Loblaw writes "I ran across a huge stash of floppies at our office, and after some discussion, it became clear that rather than throw them away, we should build a gun that fires floppies. I had just bought a welder so this was a challenging first project. After about a month of work in my garage at night the DataStorm was born. It was constructed of scrap metal, a kid's bike, a weed-eater motor, and an electric screwdriver. The most difficult task ended up being how to add spin to the disk without significantly reducing its velocity. After a week and a half of trying different options, a stack of zip ties was found to work best. Since we had so much time in it we elected to shoot an infomercial showcasing the device, and had to learn to shoot & edit video as we went. It was basically an office joke that spiraled out of control. My wife is not amused. At all. I hope you like it."

Stony Stevenson alerts us to new information on the XP SP3-induced crashes that we discussed a few days back. Jesper Johansson, a former program manager for security policy at Microsoft, is maintaining an ongoing log and support site for users affected by any of several problems triggered by XP3. Machines using AMD hardware, particularly HP desktops, seem to have several modes of failure; others affect Intel machines.

Justin Hall and Merci Hammon's networked browser-game PMOG (Passively Multiplayer Online Game) just launched after a solid beta period. The idea is to encourage people to be more adventurous and smarter when they browse the web, by awarding points for different kinds of Internet activity (for example, awarding bonuses for looking at Wikipedia history pages, comparing search results across different engines, or installing Firefox). The networked play also allows players to create their own missions and quests, and to lay traps for other players. All in all, it's great fun, and a genuinely novel way at looking at Internet literacy.

Justin sez,

PMOG is a steamy Victorian metagame about being online. The game gives its players tools to leave treasure or traps on any website, and to make guided web missions for other players. PMOG stands for Passively Multiplayer Online Game, which means you earn resources and unlock rewards just by surfing. Players in PMOG can hide the game, pause the game, or erase their histories at any time; we encourage people to experiment with and take control of their data trails. PMOG is the first MMO in Firefox , a 220k extension to enhance your browsing pleasure. PMOG players who regularly read BoingBoing get a "Bounce Bounce" badge

thermian writes "I've been developing my open source project for several years now, and I've never found a solution to one fairly important issue. How can a small-scale project attract new members? My project is pretty specialist, (no URL, sorry, I can't afford to get my server nuked) and I find that while it gets a fair bit of use, most users come to my software out of a need to solve their problem, or use my tutorials to learn about the subject, and none seem inclined to stick around and help make the product better. This is a fairly serious problem for me now, because my software has recently been adopted by a university, and I'm just not in a position to manage the entire set of applications and update everything on my own. Just preparing a version for release to students has been especially hard. The open source maxim 'Many eyes make all bugs shallow' only works if those 'many eyes' are available. So do you have any suggestions as to how, and where, to find people who fancy joining open source projects?"

Sniper223 notes a PC World article on a new kind of rootkit recently developed by researchers, which will be demoed at Black Hat in August. The rootkit runs in System Management Mode, a longtime feature of x86 architecture that allows for code to run in a locked part of memory. It is said to be harder to detect, potentially, than VM-based rootkits. The article notes that the technique is unlikely to lead to widespread expoitation: "Being divorced from the operating system makes the SMM rootkit stealthy, but it also means that hackers have to write this driver code expressly for the system they are attacking."

billybob2 writes "VIA has released 16,434 Lines Of Free & Open Source code that enables Linux natively to use the framebuffer on VIA's graphics chipsets. This comes a month after VIA announced that it will provide Open-Source drivers and documentation on its Web site so that its hardware will work out of the box with Linux distributions. This gives VIA-powered systems that come pre-installed with Linux — such as the gPC, 15.4" gBook, CloudBook, and Zonbu — the ability to output graphics through digital connections such as HDMI, and probably makes them the best-supported framebuffers Linux has ever had. Look forward to documentation and X.org drivers from VIA as well in the near future."

Consul writes "What is the oldest piece of code that is still in use today, that has not actually been retyped or reimplemented in some way? By 'piece of code,' I'm of course referring to a complete algorithm, and not just a single line." The question would have a different answer if emulation, in multiple layers, is allowed.

Das Capitolin sends us to Benchmark Reviews for an in-depth feature on DDR3 memory that begins: "These are uncertain financial times we live in today, and the rise and fall of our economy has had [a] direct [effect] on consumer spending. It has already been one full year now that DDR3 has been patiently waiting for the enthusiast community to give it proper consideration, yet [its] success is still undermined by misconceptions and high price. Benchmark Reviews has been testing DDR3 more actively than anyone... Sadly, it might take an article like this to open the eyes of my fellow hardware enthusiast[s] and overclocker[s], because it seems like DDR3 is the technology nobody wants [badly] enough to learn about. Pity, because overclocking is what it's all about."

Scientists at the European Space Agency are using techniques inspired by their experience with outer space to make new and better products here on Earth. Certain compounds and alloys which are not normally viable can be made in different ways once forces such as gravity are removed from the equation. From BBC News: "The near absence of gravity (microgravity) has a profound influence on the way molten metals come together to form intermetallics and 'standard' alloys. With no 'up' and 'down' in the space environment, a melt doesn't rise and sink as it would at the planet's surface and that means solidification can turn out very differently. 'Gravity induces a lot of segregation of the elements,' explains IMPRESS scientist Dr Guillaume Reinhart. 'For instance, tantalum and niobium are heavy atoms and in doing the solidification process on the ground, they will segregate in different places and produce a very heterogeneous material. If you do this in microgravity, you obtain a very homogenous material because you prevent separation; and you have a much more efficient material, mechanically.'"

An anonymous reader brings us IBM Developerworks' recent analysis of how the NSA built SELinux to withstand attacks. The article shows us some of the relevant kernel architecture and compares SELinux to a few other approaches. We've discussed SELinux in the past. Quoting: "If you have a program that responds to socket requests but doesn't need to access the file system, then that program should be able to listen on a given socket but not have access to the file system. That way, if the program is exploited in some way, its access is explicitly minimized. This type of control is called mandatory access control (MAC). Another approach to controlling access is role-based access control (RBAC). In RBAC, permissions are provided based on roles that are granted by the security system. The concept of a role differs from that of a traditional group in that a group represents one or more users. A role can represent multiple users, but it also represents the permissions that a set of users can perform. SELinux adds both MAC and RBAC to the GNU/Linux operating system."

sproketboy writes with news that a developer named Marc Balmer has recently fixed a bug in a bit of BSD code which is roughly 25 years old. In addition to the OSnews summary, you can read Balmer's comments and a technical description of the bug. "This code will not work as expected when seeking to the second entry of a block where the first has been deleted: seekdir() calls readdir() which happily skips the first entry (it has inode set to zero), and advance to the second entry. When the user now calls readdir() to read the directory entry to which he just seekdir()ed, he does not get the second entry but the third. Much to my surprise I not only found this problem in all other BSDs or BSD derived systems like Mac OS X, but also in very old BSD versions. I first checked 4.4BSD Lite 2, and Otto confirmed it is also in 4.2BSD. The bug has been around for roughly 25 years or more."

Roland Piquepaille writes "According to a Michigan State University (MSU) news release, 'Made-to-order isotopes hold promise on science's frontier,' nuclear physicists can now start a new career as isotope designers. These scientists can build specific rare isotopes to solve scientific problems and open doors to new technologies. The lead researcher says this approach has already given us the Positron Emission Tomography (PET) scan technology. He's now going further, saying that he wants to build objects 100,000 times smaller than the atomic nucleus. He calls this 'femtotechnology.' Also available are additional details and pictures of the tools used for this kind of research, picked from a 415-page design paper." Update: 05/11 14:30 GMT by SS: Readers have noted that the summary inaccurately portrays the scale of the 'femtotechnology.' The MSU researcher refers to "the capacity to construct objects on an even more minute scale, that of the atomic nucleus 100,000 times smaller."

From time to time people ask what the images in the margins of Scripting News mean. I don't think I've ever answered the question on the blog itself.

There are many answers to the question because they mean whatever you want them to mean. The point is to stimulate creativity. If I wrote an article about Fidel Castro, for example, and put a fiery picture of Fidel next to the piece it would satisfy curiosity. "I wonder what he looks like?" Suspense eliminated. That kind of imagery serves to quell creativity, to push it down, stifle it. It answers questions as opposed to raising them. Lowers entropy instead of increasing it.

My goal is to stimulate thinking. If people say they disagree with me -- excellent. Sometimes I disagree too. There are many sides to every question, and many of them are valid. To fix on one answer as being the only one would be to eliminate creativity, imagination. It's why stories told on radio can be so incredibly vivid compared to movies or TV. You get to supply the visuals. So if the meaning isn't obvious, you get to find your own meaning. That's better sometimes than filling in all the blanks. Create new blanks.

My pictures are supposed to raise questions. The first one might be "Why did he put that there?" You may find you have an answer, but know that that's your answer, not anyone else's. It says something about you. Or you might look at the picture and say "That's a weird picture" and not give it another thought. That's also a valid answer. Or you might be tired of the pictures and see one and choose not to read the article. More power to you!

Esther Dyson once sent an email asking why there was a big picture of herself next to an article that had nothing to do with her. "I thought it was an interesting picture" is what I said. I told the truth, the whole truth, and nothing but the truth.

I once got a call from a neighbor when I lived in the country, she said she was going to get some baby goats, and they might make a lot of noise as they were being weaned from their mother. I asked why she was getting the goats. She said she always wanted goats.

That's pretty much what the images mean.

To every yin there's a yang. Here's a brilliant counterpoint to what I've been writing here about decentralizing Twitter. I've excerpted the last paragraph because it is some of the best tech writing I've ever read. Wonderful.

Echovar: "The idea of building competitors to Twitter on the same platform, or redistributing Twitter to multiple players reminds me of the idea that New York City should be rebuilt in Ohio because it would be cheaper. Or perhaps we could distribute a little of New York City in every state of the Union. New York City is what it is because of the people who live and visit there. Building another New York City in Las Vegas doesn't result in the phenomenon that is New York City. In a very important sense, Twitter is decentralized at its core, it is rhizomatic rather than arborescent."

Wired is running a story about a recent security exercise in which the NSA attacked networks set up by various US military academies. The Army's network scored the highest, put together using Linux and FreeBSD by cadets at West Point. Quoting: "Even with a solid network design and passable software choices, there was an element of intuitiveness required to defend against the NSA, especially once it became clear the agency was using minor, and perhaps somewhat obvious, attacks to screen for sneakier, more serious ones. 'One of the challenges was when they see a scan, deciding if this is it, or if it's a cover,' says [instructor Eric] Dean. Spotting 'cover' attacks meant thinking like the NSA -- something Dean says the cadets did quite well. 'I was surprised at their creativity.' Legal limitations were a surprising obstacle to a realistic exercise. Ideally, the teams would be allowed to attack other schools' networks while also defending their own. But only the NSA, with its arsenal of waivers, loopholes, special authorizations (and heaven knows what else) is allowed to take down a U.S. network."

or_is_it writes "The company I work for has been growing dramatically and I've been charged with the task of being the gatekeeper for our GFI Spam filters. This involves manually inspecting the subject line/to/from for all caught messages in each filter rule folder. For a company of about 50 people, in one day the number of spam messages can exceed 2,000. Neglect it for a day and you end up with quite a task on your hands. I've made the rules lax enough so important messages can go through, along with a few stray spams, for which I get bitched at. Tighten the rules up and then maybe an important time-sensitive email never gets to its intended recipient, and I get bitched at. Manually reading through all those subject lines is supposed to prevent that, but I'm only human and genuine messages can easily get overlooked. How do larger organizations deal with the spam issue? I can't imagine having one centralized person manually inspecting everyone's junk-mail header is the optimal solution. Purchasing a different commercial mail filter product is a possibility, but I'd like to hear some anecdotal evidence before jumping ship."

Last week, I went to see mentalist/magician Derren Brown perform live at the Garrick Theatre in London's West End, catching the start of the run of his latest show, "Derren Brown, Mind Reader: An Evening of Wonders. It was absolutely fantastic. I'd met Derren and chatted with him, and seen his TV show, but I'd never seen him perform live. He's nothing short of brilliant.

The show doesn't feature much by way of traditional conjuring tricks, but rather builds up a sustained narrative about mind reading and skepticism, wherein Brown performs an escalating series of amazing mentalist stunts -- guessing things he should have no way of knowing, seemingly imparting his ability onto random audience members, and all the while implying at times that this is hypnosis, body-reading, mind reading, simple tricks, none of the above, and all of the above, reminding us all the while that it's just tricks, that psychic phenomena are rubbish, and so on.

The general effect is one of intense mental alertness and continuous amazement: Brown's expert misdirection, gripping stage presence, humour and patter had me thinking at a million miles a minute, trying to unravel the mysteries he presented even as fresh ones were revealed.

After the intermission, Brown came out in a formal tux and announced that he would finish the show with a revival of the Vaudeville-era "oracle" act, in which a purported mentalist answers questions from sealed envelopes. He proceeded to do so, adding variation upon variation, each one more astounding than the last. By the time it was over, I was absolutely mystified and utterly delighted.

At the show, I picked up a DVD of "Something Wicked This Way Comes," a movie version of his last touring show. It features many similar amazements (though I thought the new show really outdid the last one), and the ability to rewind and go back and still not spot the gimmick makes it all the more amazing.

Brown's new show runs to June 7. If you're in London and want to have your mind blown six ways to Sunday, this is about as good as it gets. Link to tickets at the Garrick, Link to Something Wicked This Way Comes DVD
