A 3-D Holographic Display
ZonkerWilliam sends along a link to a Wired writeup on a novel 3-D holographic display developed at USC. Be sure to watch the video at the bottom of the page. "The process is not simple but can be defined through a few key concepts: Spinning mirrors, high-speed DLP Projections, and very precise math that figures out the correct axial perspective needed for a 360-degree image (even taking into account a viewer's positioning.)"

Cool/Weird Stuff To Do On a Cluster?
Gori writes "I'm a researcher at a university. Our group mainly does Agent Based Modeling of interdisciplinary problems (think massive simulations where technology, policy, and economics meet). Recently, we managed to get a bunch of money for a High Performance Cluster to run our stuff on. The code is mostly written in Java. Our IT support people are very capable of setting up a stable cluster that will run Java perfectly. But where's the fun in that? What I'm trying to figure out are other, more far-out and interesting things to do with this machine — think 500+ Opteron cores, 2 GB RAM per core, a gigabit interconnect with some badass switches, a massive storage array, plus a bunch of UltraSPARC boxes. So at times when there's no stuff to crunch, I'd like to boot the thing up with a 'weird' system image and geek around in the name of science. Try fancy ways of building models, dynamically adding all sorts of hardware to it, etc. Have different schedulers compete for resources. Imagine a Matlab vs. Boinc vs. ProActive shootout. Maybe run plan9 on it? Most of us are not CE/CS people, but we are geeky enough. So, what would be the coolest and most far out thing you would do with this kind of hardware ?"

Water Ice On Mars
cathector sends along a story from SpaceWeather.com on the discovery of water ice on Mars. "Scientists have figured out the mysterious white substance unearthed by NASA's Phoenix lander on Mars. It's frozen water. The breakthrough came last week when Phoenix's stereo camera caught the substance in the act of disappearing. Bathed in martian sunlight for four days, the white substance sublimated — i.e., it transformed from solid to gas without passing through the liquid state. This is how water behaves on Mars.... Some readers have asked, how do we know the white substance is not frozen CO2 (dry ice) instead of frozen water? Answer: Phoenix's landing site is too warm for dry ice. The average daily temperature is about -70 F while dry ice requires temperatures lower than about -109 F." The animated GIF showing the ice sublimating is pretty nice too.

McCain Backs Nuclear Power
bagsc writes "Senator John McCain set out another branch of his energy policy agenda today, with a key point: 45 new nuclear power plants by 2030." So it finally appears that this discussion is back on the table. I'm curious how Nevada feels about this, as well as the Obama campaign. All it took was $4/gallon gas I guess. When it hits $5, I figure one of the campaigns will start to promote Perpetual Motion.

IP Traffic To 'Double' Every Two Years
Stony Stevenson writes "Web traffic volumes will almost double every two years from 2007 to 2012, driven by video and web 2.0 applications, according to a report from Cisco Systems. Cisco's Visual Networking Index (PDF) predicts that visual networking will account for 90 percent of the traffic coursing through the world's IP networks by 2012. The upward trend is not only driven by consumer demand for YouTube clips and IPTV, according to the report, as business use of video conferencing will grow at 35 percent CAGR over the same period." I left the apostrophes around the word "double" in the title because the linked site has them, but for the life of me I can't figure out why.

Metal Gear Solid 4 Review
mikesd81 brings us a detailed IGN review of the recently released Metal Gear Solid 4, which notes: "Fans familiar with previous Metal Gear Solid games are aware that each title has introduced new gameplay mechanics for Snake to take advantage of. The incredible part about Metal Gear Solid 4 is there are tons of additional features added to this title, and even when you run into a system or mechanic that you wouldn't think would fit in the Metal Gear Universe, Kojima and his team have figured out a way to make it blend seamlessly with the gameplay, which easily allays any fears or concerns you have.""

Best Chair For Desktop Coding?
wifeoflurker writes "Can someone give me recommendations for a desk chair to give my husband as a Father's Day gift? He currently uses a cheap one he got from Office Max, but I want him to have a really comfortable one. He spends his life in this chair (coding and lurking on Slashdot). I don't have time to research good chairs on the internet today (I'm chasing my 10 month old around, and she seems to get into the most mischief when I'm staring at the computer screen), so I figured a few folks here might share their personal recommendations." Has there been any great progress in the state of the art (of sitting) since the last time readers sought recommendations for back-friendly chairs a few years back, or the perfect computer chair nearly a decade back? Is there even such a thing as a back-friendly chair, or should we all be in astronaut-style lounge workstations?

Apple Cracks Down On iPhone Unlockers
An anonymous reader writes "It looks like Apple and its wireless operator partners have finally figured out a way of cracking down on iPhone unlockers by making it a requirement to sign up for a contract before you can get your hands one. "It's obvious why this has happened though. This method means you're tied into a contract, or you're paying O2 and Apple a massive wad of cash for the privilege of owning a 3G iPhone. We're disappointed about this decision, but it does make business sense." Both ATT in the US and O2 in the UK are implementing the new activation system on July 11th, when the iPhone 3G goes on sale."

Researchers Tout New Network Worm Weapon
coondoggie writes "Can Internet worms be thwarted within minutes of their infection? Researchers at Ohio State University believe they can. The key, researchers found, is for software to monitor the number of scans that machines on a network send out. When a machine starts sending out too many scans — a sign that it has been infected — administrators should take it off line and check it for viruses. In a nutshell, the researchers developed a model that calculated the probability that a virus would spread, depending on the maximum number of scans allowed before a machine was taken off line.'The difficulty was figuring out how many scans were too many,' researchers said."

First Pictures From Mars Phoenix Lander
Now that the solar panels have been deployed, the Mars Phoenix Lander has begun sending back pictures of the red planet to the hungry space geeks of earth. In just a few weeks the claw will deploy and they'll start digging a hole. The scientists expect to use the dirt to construct a little sand castle which they will defend with several GI Joe action figures, and a bald barbie stolen from their sisters. Oh, and maybe find water or bacteria.

Mozilla Dev Team On Firefox's Success
Titus Germanicus writes "If you're thinking about open sourcing a project in the near future, Mozilla might be the perfect blueprint to follow. At last week's Mesh 2008 conference in Canada, Mike Shaver, chief technology evangelist and founding member at Mozilla, and John Resig, a JavaScript evangelist at Mozilla — two of the key figures behind the success of Mozilla's Firefox Web browser — listed inclusivity and transparency as two of the top cornerstones of any community-built project. Shaver said in this interview that because the Web is intended for everybody, the level same openness should be shared with Firefox's open source contributors."

Shigeru Miyamoto, The Walt Disney of Our Time
circletimessquare writes "The New York Times has a gushing portrait of Shigeru Miyamoto. His creative successes have spanned almost 30 years, from Donkey Kong, to Mario (as well known as Mickey Mouse around the world, the story notes), to Zelda, to the Wii, and now to Wii Fit — which according to some initial rumors is selling out across the globe in its debut. The article has some gems of insight into the man's thinking, including that his iconic characters are an afterthought. Gameplay comes first, and the characters are designed around that. Additionally, his fame and finances and ego are refreshingly modest for someone of his high regard and creative stature: 'despite being royalty at Nintendo and a cult figure, he almost comes across as just another salaryman (though a particularly creative and happy one) with a wife and two school-age children at home near Kyoto. He is not tabloid fodder, and he seems to maintain a relatively nondescript lifestyle.'"

Getting Rid of Staff With High Access?
HikingStick writes "I've been in the tech field for over 15 years. After more than nine years with the same company, I've been asked to step in and establish an IT department for a regional manufacturing firm. I approached my company early, providing four weeks notice (including a week of pre-scheduled [and pre-approved] vacation time). I have a number of projects to complete, and had planned to document some of the obscure bits of knowledge I've gleaned over the past nine years for the benefit of my peers, so I figured that would give me plenty of time. That was on a Friday. The following Monday, word came down from above that all of my privileged access was to be removed — immediately. So, here I sit, stripped of power with weeks ahead of me. From discussions with my peers in other companies, I know that cutting off high-privilege users is common, but usually in conjunction with a severance offer (to keep their hands off the network during those final weeks, especially if there is any ill-will). Should I argue for restored access, highlight the fact that I am currently a human paperweight, request a severance package, or simply become the most prolific Slashdot poster over the next few weeks? Does your company have a policy/process for dealing with high-privilege users who give notice? What is it, and do you make exceptions?"

New Malware Report Hits Vista's Security Image
An anonymous reader recommends a Computerworld article on a new report from Australian security vendor PC Tools. The company released figures on malware detection by its ThreatFire product, and in its user base 27% of Vista machines were compromised by at least one instance of malware. From the article: "In total, Vista suffered 121,380 instances of malware from its 190,000 user base, a rate of malware detection per system [that] is proportionally lower than that of XP, which saw 1,319,144 malware infections from a user base of 1,297,828 machines, but it indicates a problem that is worse than Microsoft has been admitting to." Microsoft hasn't responded yet to this report.

Google, Sprint, Others to Build Wireless Data Network
Nerdposeur writes "Google has announced that it will partner with several other companies to build a high-speed mobile data network. In a separate but related deal, Google will also become the default search provider for Sprint, including having one-click search access and Google Maps pre-installed on some Sprint phones. 'The consortium includes a disparate group of partners: Sprint Nextel, Google, Intel, Comcast, Time Warner and Clearwire. The partners have put the value of the deal at $14.5 billion, a figure that includes radio spectrum and equipment provided by Sprint Nextel and Clearwire, and $3.2 billion from the others involved. They expect the network, which will provide the next generation of high-speed Internet access for cellphone users, to be built in as little as two years, but there is no timetable on when it will be available to users and the price is not determined. The partners are seeking to beat Verizon Wireless and AT&T Wireless to the market.'"

Introducing Classical Guitar Hero
Alex writes "I've just uploaded the video of a piece of classical electronic music I wrote for 2 Guitar Hero controllers and software (which I created). More information about this piece, its software, and the notation involved in playing it is at alexwroten.com/works.asp and alexwroten.com/excuses.html. I just figured people might be interested in finding new ways to use their Guitar Hero mastery ... especially with the hot debate over whether or not it hinders people's musical instruction."

US State Dept. Loses Anti-Terrorist Program Laptops
Stony Stevenson writes "It has surfaced that the US State Department can't account for up to about 1,000 laptops, perhaps as many as 400 of which belonged to the department's Anti-Terrorism Assistance Program. Internal auditors found that the department lost track of $30 million worth of computer equipment, 'the vast majority of which... perhaps as much as 99 percent,' were laptops, according to one official. Another official calculated that the average State Department laptop costs US$3,000 and figured that meant as many as 1,000 laptops might be astray — not 10,000 laptops as the US$30 million figure suggests. They're obviously not very good at maths."

Storing Data For the Next 1,000 Years
An anonymous reader writes "This may be an interesting take on creating long-term storage technologies. A team of researchers at UCSC claims to have come up with a power-efficient, scalable way to reliably store data for a theoretical 1,400 years with regular hard drives. TG Daily has an article describing this technology and it sounds intriguing as it uses self-contained but networked storage units. It looks like a complicated solution, but the approach is manageable and may be an effective solution to preserve your data for decades and possibly centuries." Nice to see research on this using the kinds of real-world figures for disk lifetimes that recent studies have been turning up.

$1/Gallon "Green Gasoline" In Sight
mattnyc99 writes "We've gotten excited here about the startup that claims it can make $1/gallon ethanol out of anything from trash to tires. But we've also seen how cellulosic ethanol is a better option, and how ethanol demand in general is only adding to the worldwide food crisis. So what about $1/gallon gasoline? NSF-funded researchers at UMass Amherst just completed the first direct conversion from cellulose using a new method of hydrocarbon refining, which they claim can be commercialized within 5-10 years and essentially make fuel out of anything that grows. Quoting: 'We already have the infrastructure in place to distribute liquid fuels. We're using them to power transportation vehicles today, and I think that's what we'll be using in 10 years and in 50 years,' Huber says. 'And if you want a sustainable liquid transportation fuel, biomass is the only way to go.'" The process is running at about 50% efficiency now; the $1/gallon figure is based on getting to 100%.

WiiMan, the Nintendo Wii Super Hero
rafaelmizrahi writes "WiiMan the Super Hero is a full action figure costume of a super hero that functions as a Nintendo WiiMote remote. Having trouble playing Wii? WiiMan to the rescue. This GarageGeeks project combines Gaming, Technology and Useless Activity to the extreme. Rafael Mizrahi, an artificial vision and experience explorer at Feng-GUI and a GarageGeeks member along with Yael Hertzog built this custom costume that acts as a fully functional Nintendo WiiMote remote with buttons, bluetooth, accelerometers, and an IR cam. BTW, last year, they built another hero, The Guitar Hero Noid, a robot built with Tal Chalozin that plays the PlayStation game Guitar Hero." (You might have better luck reaching the GarageGeeks site's Google cache.)
