Move Over AJAX, Make Room for ARAX 409

sasserstyl writes "eWeek reports that Microsoft's Silverlight platform will support Ruby client-side scripting, enabling ARAX — or Asynchronous Ruby and XML. Would be cool to have the option to script client-side in something other than Javascript. 'In essence, using ARAX, Ruby developers would not have to go through the machinations of using something like the RJS (Ruby JavaScript) utility, where they write Ruby code and RJS generates JavaScript code to run on the client, Lam said. "Sure, you could do it that way, but then at some point you might have to add some JavaScript code that adds some custom functionality on the client yourself," he said. "So there's always that sense of, 'Now I'm in another world. And wouldn't it be nice if I have this utility class I wrote in Ruby...' Today if I want to use it in the browser I have to port it to JavaScript. Now I can just run it in the browser."'"

Conference Robot Connects Offices in Different Countries 89

An anonymous reader writes "With travel getting so expensive this sure would be a neat way to connect people in separate offices and not just when they are overseas: 'Minneapolis-based PowerObjects Inc. has created an innovative tool to communicate with its development team in Islamabad, Pakistan. It's a 5-foot-3-inch, 215-pound robot called POGO — a sort of rolling, computer-screen on wheels mounted with a webcam that bears a slight resemblance to the R2D2 of "Star Wars" fame.'"
Supercomputing

Supercomputer Built With 8 GPUs 232

FnH writes "Researchers at the University of Antwerp in Belgium have created a new supercomputer with standard gaming hardware. The system uses four NVIDIA GeForce 9800 GX2 graphics cards, costs less than €4,000 to build, and delivers roughly the same performance as a supercomputer cluster consisting of hundreds of PCs. This new system is used by the ASTRA research group, part of the Vision Lab of the University of Antwerp, to develop new computational methods for tomography. The guys explain the eight NVIDIA GPUs deliver the same performance for their work as more than 300 Intel Core 2 Duo 2.4GHz processors. On a normal desktop PC their tomography tasks would take several weeks but on this NVIDIA-based supercomputer it only takes a couple of hours. The NVIDIA graphics cards do the job very efficiently and consume a lot less power than a supercomputer cluster."

Network Measurement Tool Detects Reset Packets 118

kickassweb writes "If you think your ISP is sniffing packets, or worse yet, sending reset packets to stop torrents, there's now a beta Network Measurement Tool to detect them, courtesy of Lauren Weinstein of the Net Neutrality Squad. It's released under the LGPL, and runs under Win2K, XP, and Vista. Quoting: 'While the reset packet detection system included in this release is of interest, NNSquad views this package as more important in the long run as a development base for a broad range of network measurement functionalities and associated communications and analysis efforts.'"

HyperCard, What Could Have Been 159

bobwrit sends us to Wired for a look back by the author of HyperCard, Bill Atkinson. Quoting: "HyperCard is a programming environment that can create applications as diverse as utilities and games by linking 'cards' arranged into 'stacks.' Commands are executed through a natural-language scripting language called HyperTalk... The software has been phenomenally successful and highly influential. But Atkinson feels that if only he'd realized separate cards and stacks could be linked on different people's machines through the Net — instead of cards and stacks on a particular machine — he would have created the first Internet browser."

Best Way to Start a Website Hosting Service? 164

Kwirl writes "Lets say that I wanted to start a small business endeavor, namely reselling my server space and offering pre-built websites. What resources would I need to start something like this on my own? What hosting service would best suit those needs? What would be the best way to manage a subdomain-level service that provided a basic forum, registration, a web site and some controlled administrative access for my friends so they couldn't easily terrorize each other? I'm curious to know if I could start something like this on my own, and without much more than just my own server space, time, and creativity. I'm not looking to make a living out of this, its mostly just a way for me to more efficiently manage having several friends each wanting me to built or run a web site for them, and perhaps make some small residual income if a market exists. The Slashdot community represents such a broad swath of experience and expertise that I'd like to know how you would approach a project of this nature."

Wearable Motorcycle Design 234

A motorcycle design student recently came up with a wearable motorcycle design that, while cool, is unlikely to see public adoption. The bike would be capable of doing 0 to 60 is just 3 seconds with a top speed of 75 miles-per-hour and would theoretically be controlled by 36 pneumatic muscles and 2 linear actuators. I would imagine the results of a crash would be much like being strapped to the hood of your car during a collision — bonus points for form, however.
It's funny.  Laugh.

New Urinal-Based Video Game Makes a Splash 176

Those who enjoy drinking beer, playing video games, and (oddly enough) peeing in urinals may be able to reach true nirvana after all. "Place to Pee" is a new video game that relies on a player's ability to hit sensors in a urinal to control game play. While this may seem extremely male-centric, don't worry, ladies, the game designers have thought of you too, and have designed a specialized paper cone for participation. Man, it's a bad day to be a janitor.

What to Seek in an Older Subnotebook? 250

cyclomedia writes "I'm looking to buy a subnotebook. For those who think that this form factor was created by the Asus EEE (as, seemingly, does Wikipedia) it might interest you that the current forerunner in my search is a 190MHz,64MB,640x480 256 colour beastie known as the Psion Netbook, circa 2001-ish. Basically, I have a desktop, a server and an Xbox and so truly only want it for surfing, email and the odd bit of SSHing home on weekends away. The aforementioned Psion is, however, of the StrongArm processor variety, which nudges it down on the desireability meter, but the fact that there exist Wi-Fi cards for its 16-bit PCMCIA slot does score it extra points. So, anyone here got any suggestions of what to look out for on ebay? So long as I can play Doom II on it too, that is." Any other suggestions for wireless capable subnotebooks with better battery life than things like the EEE or HP's 2133 Mininote?

China Buying US Directed Sound 'Weapon' 350

holy_calamity writes "The directed sound weapon made by US company ATC is being exported to the Chinese police, despite the public law banning sales of weapons to China. Turns out that such 'non-lethal' technologies are not covered by this law — an omission that may become more widely known if they are used to quell high-profile protests during the Olympics."

A Billion-Color Display 206

The Future of Things covered the introduction last month of HP's DreamColor display, with 30 bits/pixel, developed in conjunction with DreamWorks Animation. The display is aimed at the video production, animation, and graphic arts industries. HP promises blacker blacks and whiter whites — though TFoT quotes one source who notes that if they deliver this, it will be due to the back-lighting and not to the number of bits/pixel. No word on the size of the displays that will actually be delivered, or on the price.

Google's Shareholders Vote Against Human Rights 376

yo_cruyff notes a Computerworld article on Google's recent annual shareholder meeting, which was dominated by argument over the company's human rights policies. Google's shareholders, on advice from their board, have voted down two proposals on Thursday that would have compelled Google to change its policies. "Google [has been] coming under fire for operating a version of its search engine that complies with China's censorship rules. Google argues that it's better for it to have a presence in the country and to offer people some information, rather than for it not to be active in China at all... [S]hareholders and rights groups including Amnesty International... continue to push Google to improve its policies in countries known for human rights abuses and limits on freedom of speech... Sergey Brin, cofounder and president of technology for Google, abstained from voting on either of the proposals. 'I agreed with the spirit of these proposals,' Brin said. But he said he didn't fully support them as they were written, and so did not want to vote for them."

Smartphone Battle Is Shaping Up As RIM Vs. Apple 261

TeknoFin notes a piece in the NYTimes on the fight RIM finds itself in as the smartphone market shifts to a consumer focus, impelled by the iPhone. For the last 10 years RIM has dominated a smartphone market consisting mainly of email-obsessed corporate professionals. Analysts wonder if RIM can hold on to their lead as their strengths — such as cozy relations with cell carriers worldwide — are diluted by new entrants Apple and Google, who are "vocally trying to dislodge the carriers from the nexus of the North American wireless market." One of RIM's strengths in the corporate market has been their security. Yet Apple executives have said that one-third of Fortune 500 companies were interested in giving iPhones — with all their known and potential security holes — to their employees.
