US Navy Tries To Turn Seawater Into Jet Fuel 402

Hugh Pickens writes "New Scientist reports that, faced with global warming and potential oil shortages, the US Navy is experimenting with making jet fuel from seawater by processing seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. The process involves extracting carbon dioxide dissolved in the water and combining it with hydrogen — obtained by splitting water molecules using electricity — to make a hydrocarbon fuel, a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal. The Navy team have been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane by finding a different catalyst than the usual one based on cobalt. 'The idea of using CO2 as a carbon source is appealing,' says Philip Jessop, a chemist at Queen's University adding that to make a jet fuel that is properly 'green,' the energy-intensive electrolysis that produces the hydrogen will need to use a carbon-neutral energy source; and the complex multi-step process will always consume significantly more energy than the fuel it produces could yield. 'It's a lot more complicated than it at first looks.'"

Xbox Gaming Platform To Span Web, Console, Mobile 33

An anonymous reader writes with this excerpt from Ars Technica: "According to a job posting from August 10, 2009, Microsoft is looking for a LIVE Community Director in the Entertainment & Devices Division. The job posting seems to suggest that Microsoft is looking to bring the Xbox Live, Windows Mobile, and other similar properties closer together. More specifically, there's talk of a 'casual and social gaming platform' that would be available via more than just one device: 'The LIVE Engagement Team is looking for a LIVE Community Director to manage its LIVE community strategy and execution across a range of properties, from Xbox LIVE to Windows Mobile. This senior position will play a vital role in the community space as the LIVE Engagement team builds and program's Microsoft's next-generation, LIVE-enabled casual and social gaming platform across the Web, the console, mobile and beyond.' The first key responsibility listed in the job posting is to '[d]evelop a community strategy that leverages all parts of the LIVE Services team to deliver scenarios and engagement across three screens.'"

Similar experience here. My Compaq Presario R4000 laptop stopped working abruptly while I was sitting in the university lab. It wasn't even plugged in, was running off the battery, and the display just went blank. The LCD had probably conked off, for I could run an external DFP off it. Anyway, since it was still under warranty, I shipped it off. I got a call from the service center, saying that I had dropped liquid on it, and the hard drive, motherboard, CPU and LCD were all shot and had to be replaced, and gave me a bill of around $700 (original cost of the laptop was $1200). I was livid, but no amount of reasoning/cussing changed anything. "We'll ship it back if you don't want to fix it". Fucking turds, those Compaq folks. Will never buy anything from them every again, and anyone who's heard this story has refused to touch HP/Compaq again.
Oh and the best part? I had purchased a $99 user-damage covering on-year warranty from them when I bought the laptop. So they had to replace everything or me, essentially handing me a new laptop. I got lucky.

Cheap, Cross-Platform Electronic Circuit Simulation Software? 211

dv82 writes "I teach circuits and electronics at the undergraduate level, and have been using the free student demo version of OrCad for schematic capture and simulation because (a) it comes with the textbook and (b) it's powerful enough for the job. Unfortunately OrCad runs only under Windows, and students increasingly are switching to Mac (and some Linux netbooks). Wine and its variants will not run OrCad, and I don't wish to require students to purchase Windows and run with a VM. The only production-quality cross-platform CAD tool I have found so far is McCad, but its demo version is so limited in total allowed nets that it can't even run a basic opamp circuit with a realistic 741 opamp model. gEDA is friendly to everything BUT Windows, and is nowhere near as refined as OrCad. I would like students to be able to run the software on their laptops without a network connection, which eliminates more options. Any suggestions?"

Are Console Developers Neglecting Their Standard-Def Players? 200

The Digital Foundry blog takes a look at how the focus on high-quality graphics in console game development may be lost on more gamers than people realize. According to Mark Rein of Epic Games, more than half of Gears of War 2 users played the game on a standard-definition television. While you might expect that dropping the graphics quality would correspond to a boost in frame rates, that turns out not to be the case, and running at standard definition can actually be a detriment in some cases. Quoting: "PAL50 is mandatory for SD gameplay on all games on all European PS3s. You can't avoid running at a sub-optimal 50Hz unless you splash out on a high-def screen. The Euro release of Killzone 2 works at SD resolution on any PS3, even if it can only run at PAL50 on a Euro machine. In short, if you're a Euro PS3 owner playing Killzone 2 on a standard-definition display, you're losing around 17 per cent of the frame-rate owing to the lack of PAL60 support in the PS3 hardware. The game itself isn't slower as such (as was often the case in the Mega Drive/SNES era), and you'll note that it's effectively a sustained 25FPS while the 60Hz versions can be somewhat more variable. But Killzone 2 is already somewhat laggy in its control system and this impacts the feel of the game still further. While there is a 17 per cent increase in resolution, this is far less noticeable than the additional numbness in the controls."

Stroustrup Says New C++ Standard Delayed Until 2010 Or Later 501

wandazulu writes "At the end of an article written by the creator of C++, where he talks about removing a feature from the new C++ standard, he drops a bombshell: The new C++ standard (typically referred to as C++0x) has been delayed until 2010 or later. What does this mean? No new C++ features like threads, proper enum classes, or hash tables. C++0x is dead, long live C++1x!"

Music Game Genre On the Decline 225

After enjoying several years of popularity, music games seem to be drawing less and less interest from gamers lately. Guitar Hero and Rock Band titles have been conspicuously absent from a list of the 20 best-selling software titles in the past two months, and one report estimates that revenue from those games has dropped by almost half. Analyst Jesse Divnich suggests that there's no longer much room for dramatic improvements in game play, saying, "it would be erroneous to assume that any franchise or brand can grow unless it brings something new to the table. After a while, utility to the gamer will diminish and he/she will surely move on." Nevertheless, the companies are happy to continue to rely on DLC sales while working on new releases. Harmonix is showing off a trailer and a partial set list for The Beatles: Rock Band, and Neversoft has detailed a number of new features and tracks for Guitar Hero 5.

Alaskan Blob Is an Algae Bloom 130

Bryan Gividen writes "Time.com is running a story on the previously unidentified blob floating off of the coast of Alaska. The article states that the blob is an algae bloom — far less sinister (or exciting) than any The Thing or The Blob comparison that was jokingly made. From the article: '"It's sort of like a swimming pool that hasn't been cleaned in a while." The blob, Konar said, is a microalgae made up of 'billions and billions of individuals.'"

Yeah, Vista-32 on my laptop with 4GB RAM shows 3.5GB RAM installed. I have an 8600M with a 256 MB framebuffer so all PCIE devices including it fit in that 0.5GB. I use Linux-32 as my primary desktop though, which I think uses HIGHMEM to access memory above 896MB (more knowledgeable kernel hackers correct me if I'm wrong), which isn't too efficient. One of these days I'll install a 64-bit OS, I keep telling myself.

No, Windows can only access 3.5GB of system memory, the remaining 0.5GB will be mapped above 4GB in the physical address space. When you have lots of PCI devices in the system, they take up some space in the physical address space. So if your PCI(E) devices take up 1GB of space, the BIOS will fit less of that 4GB of RAM into the 4GB physcial address space. Your PCI devices would would already be allocating BARs like I said earlier. Like AC said, you can enable PAE to reclaim some of that lost space. I know there is a flag in XP (Run:msconfig, Advanced:) to enable PAE, but I don't know if that has any effect.
