charliezcc writes "My grandmother recently fell and broke two vertebrae (among other things) and is in the hospital while she recovers. Thankfully, she was not paralyzed and retains the use of her limbs. However, they have placed her on a respirator and she is virtually unable to communicate with us, so while we try to keep her company during her recovery, our company is reduced to mainly one-sided conversations. Asking her questions, even yes/no questions, is hard because of the neck brace — it turns into a guessing game and very quickly becomes frustrating for both parties. I'm a firm believer in the power of positive mental attitudes and to make her recovery a little better and I'd like to be able to facilitate two-sided conversations with her so she can keep positive. Keeping in mind that she does not have much technology experience, what would you suggest I utilize to ease the communication barrier? I remember seeing devices with a number of buttons that say whatever you program it to say, but I can't find these anymore. What other kind of devices are available?"

hmccabe writes "YouTube is currently taking submissions for their next debate, in which the Republican candidates will answer questions. This seems like a good opportunity to challenge those candidates who say they do not believe in evolution. But since I am not an expert in the subject, I would be interested in how you all feel the question should be presented. For my own part, I think it is important to present the overwhelming body of evidence on the subject as incontrovertible fact, much the same way DNA evidence is presented during a criminal trial, and ask why the candidate feels they can pick and choose what facts they believe in. Moreover, I am wary of coming across like Christopher Hitchins, so vitriolic the candidate will defend themselves rather than answer the question. Perhaps the most important aspect of posing the question is to inform the viewers who watch the debate that this is really not a matter of opinion, but of science. So my question is: 'Hey geneticists, have you considered addressing evolution in the YouTube debates? Can you do it in 30 seconds?'"

vipermac writes "Most of the times I have a problem with a Web page loading slow or freezing temporarily, I look down at the status bar and see that it's waiting on an ad server, Google Analytics, or the like. It seems to me that on popular Web sites the bottleneck is overwhelmingly on the ad servers now and not on the servers of the site itself. In my opinion we need a better model for serving ads — or else these services need to add more servers/bandwidth. Are there any studies on the delay that 3rd-party ad servers are introducing, or any new models that are being introduced to serve ads?"

i_like_spam writes "As reported in the NYTimes, high school freshmen at many high schools across the nation are now being forced to pick a major. Starting this Fall, 9th graders in Florida will have to choose to major from among a set of state-approved subjects, while some students in Mississippi will have to follow one of nine designated career paths. High school administrators hope that having students declare majors will lead to greater student interest in school until graduation. College administrators think otherwise: 'youngsters should instead concentrate on developing a broad range of critical thinking and communication skills,' says Debra Humphreys from the Association of American Colleges and Universities."

Michael J. Ross writes "One of the most powerful and popular content management systems (CMSs) is Joomla, a superior derivative of Mambo. Out of the box, Joomla makes it relatively easy to build Web sites that allow collaborative editing of content, attractive styling via prebuilt templates, and many more features. A Joomla-based site can be further improved by adding custom modules, components, and other extensions to the CMS, without any modification to the core Joomla code. A resource that explains how to do this, is Learning Joomla! 1.5 Extension Development: Creating Modules, Components, and Plugins with PHP, by Joseph L. LeBlanc." Read on for the rest of Michael's review.

willdavid sends us to the ZDNet blogs for a provocative opinion piece by John Carroll. He points to Microsoft's evident cross-platform strategy with Silverlight, and wonders whether the company couldn't make money — and win friends — by extending its excellent development ecosystem cross-platorm. "Microsoft, apparently, is helping the folks at Mono to port Silverlight to Linux. This is good news, as the primary fear I've heard from developers is that Silverlight will be locked to Microsoft platforms and products. Microsoft has already committed to supporting Silverlight cross-browser on Windows, and has a version that runs on Mac OS X (which is even available from the Apple web site). The last step is Linux, and Microsoft is working with Novell and Mono to make this happen."

Vinit writes "The popularity of Windows XP is still making things difficult for Vista. Now Vista has again suffered a major setback, with Lenovo (Olympic 2008' official sponsor) installing XP on it's machines to run the Olympic Games' vital PC-related tasks. Vista will only be used in internet lounges set up for athletes to use during the games."

BillOfThePecosKind writes "Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. Purdue researchers funded by Intel have improved the "heat-transfer coefficient" by some 250%. I never liked water cooled systems, and this sounds promising. However I wonder how much ozone one of these things produces."

A user writes "Researchers at Rensselaer Polytechnic Institute have developed a combination battery/capacitor by infusing carbon nanotubes and electrolytes into a paper substrate. The material can be folded, rolled up, or molded to any convenient shape with no effect on power capacity. Operating temperature range is -100 to 300 degrees F. One of the co-authors is quoted: 'We're not putting pieces together — it's a single, integrated device. The components are molecularly attached to each other: the carbon nanotube print is embedded in the paper, and the electrolyte is soaked into the paper. The end result is a device that looks, feels, and weighs the same as paper.'" The researchers haven't yet developed a high-volume way to manufacture the devices. They envision ultimately printing sheets between rollers like newsprint.

ttsiod writes "An internet connection is not always at hand. I wanted to install Wikipedia on my laptop to be able to carry it along with me on business trips. After trying and rejecting the normal (MySQL-based) procedure, I quickly hacked a much better one over the weekend, using open source tools. Highlights: (1) Very fast searching. (2) Keyword (actually, title words) based searching. (3) Search produces multiple possible articles, sorted by probability (you choose amongst them). (4) LaTeX based rendering for mathematical equations. (5) Hard disk usage is minimal: space for the original .bz2 file plus the index built through Xapian. (6) Orders of magnitude faster to install (a matter of hours) compared to loading the 'dump' into MySQL — which, if you want to enable keyword searching, takes days."

Bithmus writes "I have been tasked with finding a way for our company to handle our laptop backups. We currently have nightly backups of our servers, but no backups of laptops. In our business we develop, implement, and sell another company's software; I guess that makes us a Valued Added Reseller. During development our consultants will create copies of a customer's database on MSDE on their laptops. If a hard drive crashes, all of the work done on that laptop is lost. There are other files that need to be saved, but the databases are really the important items. Ideally these databases would be stored on the SQL servers and the other files stored on the file server, but this is not happening. What do Slashdot readers do to protect data on laptops or computers outside of a local network?"

According to a senior designer on the 2K Boston (formerly Irrational) game Bioshock a number of publishers turned them down when the company brought the title to their doorstep. "Ken (Levine) spent years pitching the game to publishers but no one was interested, incredible as that seems now. I joined Irrational in December 2004 and my first job was to get a publishing deal for the game (I worked as the Business Development Director for the first six months). I remember pitching the game to one publisher who later told a friend of mine that it was 'just another f-ing PC FPS that's going to sell 250,000 units." Just in case you didn't catch it over the weekend, there's a demo for the game up on Xbox Live. PC owners hold tight: a PC demo is coming, and hopefully before the game launches on the 21st.

Abdul tips a thin little review up at The Inquirer of the Themis Slice. "The Slice is a three socket Opteron machine with two PCIe slots and two Infiniband 4x ports... Why would you want three sockets rather than four? Easy, latency. Any CPU in a 3S system is one hop away from any other CPU. In a 4S system, you can be two hops away. This adds latency, and more importantly, you take a big hit on cache coherency latency. This kills performance."

EconolineCrush writes "As a technical milestone, Hitachi's Deskstar 7K1000 hard drive is undeniably impressive. The drive is the first to pack a trillion bytes into a standard 3.5" form factor, and while some may argue the merits of tebi versus tera, that's still an astounding accomplishment. Hitachi also outfitted the drive with 32MB of cache—double what you get with standard desktop drives—making this latest Deskstar a leader in both cache size and total capacity. That looks like a great formula for success on paper, but how does it pan out in the real world? The Tech Report has tested the 7K1000's performance, noise levels, and power consumption against 18 other drives to find out, with surprising results."

PoliTech writes "iPhone bills are surprisingly large - 'Xbox Large', according to Ars technica: 'AT&T's iPhone bills are quite impressive in their own right. We're starting to get bills for the iPhone here at Ars, and while many of us have had smartphones for some time, we've never seen a bill like this. One of our bills is a whopping 52 pages long, and my own bill is 34 pages long. They're printed on both sides, too. What gives? The AT&T bill itemizes your data usage whenever you surf the Internet via EDGE, even if you're signed up for the unlimited data plan. AT&T also goes into an incredible amount of detail to tell you; well, almost nothing. For instance, I know that on July 27 at 3:21 p.m. I had some data use that, under the To/From heading, AT&T has helpfully listed as Data Transfer. The Type of file? Data. My total charge? $0.00. This mind-numbing detail goes on for 52 double-sided pages (for 104 printed pages!) with absolutely no variance except the size of the files.' You would think that a data company would have a more efficient billing process."
