The Arthur C. Clarke Gamma Ray Burst 120

Larry Sessions, a columnist for Earth & Sky, has suggested in his blog that the gamma-ray event whose radiation reached us a few hours before Arthur C. Clarke died, and which occurred 7.5 billion years ago, be named the Clarke Event. The outburst, which produced enough visible light to render it a naked-eye object across half the universe, is officially designated GRB 080319B. What more fitting tribute to Clarke than to associate his name with the greatest bang since the big one? Sessions suggests writing to any astronomers, heads of physics departments, or planetarium operators you know and talking up the proposal.

Google Looks to "White Space" Spectrum 95

Nerdposeur writes "After maneuvering the major carriers into agreeing to open access rules via the recent spectrum auction, Google appears to be looking into a new area of spectrum that could provide internet connectivity. 'In comments filed with the Federal Communications Commission, the Internet leader outlined plans for low-power devices that use local wireless airwaves to access the 'white space' between television channels. A Google executive called the plan 'Wi-Fi 2.0 or Wi-Fi on steroids.' Interestingly, Google has Microsoft, Intel, and others on their side in this one. Was this spectrum their target all along?"

NVIDIA Quad SLI Disappoints 427

Vigile writes "While the death of PC gaming might be exaggerated, it's hard not to see the issues gamers have with the platform. A genre that used to dominate innovation in the field now requires a $1200 piece of graphics technology just to participate, and that's just plain bad for the consumer. NVIDIA's SLI technology was supposed to get a boost today by going from two GPUs to four GPUs with the introduction of Quad SLI but both PC Perspective and HardOCP seem to think that NVIDIA drastically missed the mark by pushing an incredibly expensive upgrade that really does nothing for real-world game play and performance. If PC gamers are left with these options to save them from consoles, do they even have a chance?"
Hardware Hacking

From "Happy Hacking" to "Screw You" 243

tquid writes "Trying to bridge the digital divide in Canada's poorest postal code, a principled group of hackers adopt "open source"-based technology spun off from an MIT project. Then the terms on the hardware are changed, and changed again, and then firmware to lock out the frustrated group's software is installed, screwing them out of their investment and many hours of development work."

Beer-Drinking Scientist Debunks Productivity Correlation 130

austinpoet writes in with a blog post debunking the theory we discussed a few days back that scientists' beer consumption is linearly correlated with the quality of their work. Chris Mack, Gentleman Scientist and beer drinker, has analyzed the paper and found it is severely flawed. From his analysis: "The discovered linear relationship between beer consumption and scientific output had a correlation coefficient (R-squared) of only about 0.5 — not very high by my standards, though I suspect many biologists would be happy to get one that high in their work... Thus, the entire study came down to only one conclusion: the five worst ornithologists in the Czech Republic drank a lot of beer."

Calculating the Date of Easter 336

The God Plays Dice blog has an entertaining post on how the date of Easter is calculated. Wikipedia has all the messy details of course, but the blog makes a good introduction to the topic. "Easter is the date of the first Sunday after the first full moon on or after March 21... [T]he cycle of Easter dates repeat themselves every 5,700,000 years. The cycle of epacts (which encode the date of the full moon) in the Julian calendar repeat every nineteen years. There are two corrections made to the epact, each of which depend[s] only on the century; one repeats (modulo 30, which is what matters) every 120 centuries, the other every 375 centuries, so the [p]air of them repeat every 300,000 years. The days of the week are on a 400-year cycle, which doesn't matter because that's a factor of 300,000. So the Easter cycle has length the least common multiple of 19 and 300,000, which is 5,700,000 [years]."

Linux Gains Native RTOS Emulation Layer 89

nerdyH writes to tell us that the Xenomai/SOLO project is attempting to deliver VxWorks and other RTOS emulation for any Linux kernel. "Some weeks ago, I started laying the groundwork for porting the Xenomai emulators natively over the PREEMPT_RT kernel. Unlike the co-kernel based Xenomai version, SOLO does not require any kernel support from additional modules or patches. It is fully based on the standard POSIX library, and runs as a regular process controlled by a single image Linux kernel. As a first step, a VxWorks emulator has just been rebuilt over this new framework."

Submission + - Linux gains native RTOS emulation layer (linuxdevices.com)

nerdyH writes: Newly available RTOS emulation software could significantly increase Linux's utility in industrial computing applications. The Xenomai/SOLO project aims to provide VxWorks and other RTOS emulation in user-space on most any Linux kernel. That could really help modernize a lot of factory equipment, HVAC systems, and other computer-based infrastructure, by simplifying the process of migrating to modern hardware running Linux while still leveraging existing software assets.

Ubuntu 8.04 Beta Released 214

markybob writes "Ubuntu Hardy 8.04 beta has been released. It features GNOME 2.22 and uses Linux kernel 2.6.24. Furthermore, it uses Firefox 3 beta 4, and PulseAudio is enabled by default. To ease the transition of Windows users, it includes Wubi, which allows users to install and uninstall Ubuntu like any other Windows application. It does not require a dedicated partition, nor does it affect the existing bootloader, yet users can experience a dual-boot setup almost identical to a full installation."

How To Use a Terabyte of RAM 424

Spuddly writes with links to Daniel Philips and his work on the Ramback patch, and an analysis of it by Jonathan Corbet up on LWN. The experimental new design for Linux's virtual memory system would turn a large amount of system RAM into a fast RAM disk with automatic sync to magnetic media. We haven't yet reached a point where systems, even high-end boxes, come with a terabyte of installed memory, but perhaps it's not too soon to start thinking about how to handle that much memory.

Linux Powers Lilliputian PCs 193

An anonymous reader writes "Gumstix is launching a whole line of dinky little PCs little larger than a Big Red Plenty Pack. The first Netstix model targets server, sniffing, and network simulation. The next model will be USB-powered, followed by models with SD/MMC slots and built-in WiFi. They come with Linux 2.6.17, and lots of room for user applications."

Best Online Remote Backup Service w/Linux Client? 70

technocraft asks: "I've been searching for an online service to backup data from my Linux file server and have come up with nothing. For many users, Carbonite looks to be a great solution: Affordable, with 'unlimited' capacity. Unfortunately for me, you can only backup from Windows XP and explicitly NOT from external drives or network mapped drives (like my file server)." Is anyone aware of an online backup services without these restrictions?

Another Microsoft Exec Joins Google 243

SirClicksalot writes "CNN is reporting that Vic Gundotra, a 15-year veteran general manager at Microsoft, has left the company to join Google. Gundotra worked at Microsoft as general manager for platform evangelism to get software developers to use Microsoft's software and online offerings. The function he will perform at Google is not yet known, but he will need to wait one year before starting his new job because of a non-compete clause in his contract."

S3 Tries to Get Back Into PC Graphics 171

mikemuch writes "ExtremeTech has a review of S3's attempt to get some traction in the lower-end graphics card market, the Chrome S27. Though its specs look great--256MB memory, 700MHz core clock rate, 1.4GHz memory clock, and 22.4 GB/sec memory throughput, it still manages to underperform similarly priced video cards from the red and green graphics companies."
