Data Locking In a Web Application?
An anonymous reader writes "We recently developed a multi-user application and deployed it to our users. This is a web-based application that used to be a Windows application which was written in Delphi using Paradox databases for the client database. In the Windows application, we used the ability in Paradox to lock records which would prevent users from editing the same data. However, in the web application we did not add in a locking facility for the data due to its disconnected nature (at least that's how I was shot down). Now our users are asking to have the locking back, as they are stepping on each others' edits from time to time. I have been assigned to look at best practices for web application locking of data, and figured I would post the question here to see what others have done or to get some pointers to locations for best practices on doing locking with in a web application. I have an idea of how to do this, but don't want to taint the responses so I'll leave it off for the time being."Read more of this story at Slashdot.
Making Safer Lithium-Ion Batteries
itwbennett writes "Exploding iPhones may be a thing of the past. Researchers at Taiwan's Industrial Technology Research Institute have developed a new polymer, STOBA (that's self-terminated oligomers with hyper-branched architecture to you and me), that is added to the cathode material inside a lithium-ion battery to keep them from overheating. 'Fires or explosions in these batteries are caused by short circuits,' said Wu Hung-chun, a researcher at ITRI, explaining that even minor mishandling such as dropping the handset could result in damage causing a short circuit. 'The technology is ready for lithium-ion batteries used in electronic devices, mobile phones, laptops,' said Wu. And ITRI has started testing STOBA on electric car batteries."Read more of this story at Slashdot.
High-Tech Gadgets Can Pose Problems At Mexican Border
TechnologyResource writes "Going across the border will be a more 'interesting' experience since Customs and Border Protection will now be checking laptops, digital cameras, cell phones and any other electronics on your person or in your vehicle. It's not a new authority, according to Angelica De Cima, Office of Public Affairs Liaison 'They've always had the right to inspect your person, vehicle, baggage, anything on you. Nothing has changed from before,' De Cima said."Read more of this story at Slashdot.
New Images Reveal Pure Water Ice On Mars
Matt_dk writes "Images of recent impact craters taken by the HiRISE Camera on the Mars Reconnaissance Orbiter have revealed sub-surface water ice halfway between the north pole and the equator on Mars. While the Phoenix lander imaged subsurface ice where the top layer of soil had been disturbed at the landing site near the north pole, these new images — taken in quick succession, detecting how the ice sublimated away — are the first to show evidence of water ice at much lower latitudes. Surprisingly, the white ice may be made from 99 percent pure water."Read more of this story at Slashdot.
Idaho Tops America's Most-Spammed States
An anonymous reader writes "MessageLabs unveiled a list of the top US spammed states, with surprising results — the spam capital of the US is Idaho, with 93.8 percent of spam, far exceeding the global spam rate for September 2009 of 86.4 percent. Idaho has jumped 43 spots since 2008 when it was ranked the 44th most spammed state. The difference can be attributed to the resilient and aggressive botnet market as well as a higher volume of global spam that has ensued since the beginning of the credit crisis toward the end of 2008."Read more of this story at Slashdot.
Shuttleworth Suggests 1-Way Valve For User Experience Testing
darthcamaro writes "No surprise but Ubuntu's Mark Shuttleworth has come out swinging in favor of the Linux desktop. Speaking at Linuxcon yesterday he detailed the things that he thinks Linux requires in order to win the desktop wars. Those include: co-ordinated software releases, better quality and design, some user experience testing and oh yeah, a dose of 'shut the f*** up' too. During his keynote, he extended an invitation to any open source application to submit their software for testing by user-experience experts. The sessions would be recorded for posterity, and the developer would not be able to interact with the user. "'If the developer is in the room, they have to say nothing. It's the shut the f*** up protocol,' Shuttleworth said. 'You sit and watch someone struggle with the software that you've so lovingly produced.'"Read more of this story at Slashdot.
First-Ever USB 3.0 Hard Drive
dreemteem writes "After 8 years of success, the USB 2.0 standard has begun its long journey into obsolescence. Dutch storage company Freecom has announced the first mainstream storage product based on 'SuperSpeed' USB 3.0. Buyers will be interested to hear that the new external Hard Drive XS 3.0 doesn't cost the earth at £99 (approx $160) for a 1TB drive, even though that excludes the £22.99 for a desktop PCI-bus controller necessary to make it work at its intended throughput. Laptop users can pair it with a £25.99 plug-in PC Card to achieve the same effect."Read more of this story at Slashdot.
Honda's Answer To the Segway
lcreech writes with an excerpt from the Daily Mail's description of a new Segway-style one-person vehicle being shown off by Honda: "The vehicle looks like a very modern unicycle and to ride it you simply lean your weight in the direction you want to go, whether that's forward, backwards or even sideways. It maintains its own balance travelling up to 3.7MPH. Not very fast."Read more of this story at Slashdot.
New OLPC Laptop 1.5 Dual-Boots Sugar, Gnome Desktop
griffjon writes "The new hardware release (you can read about the upgrade here) also comes with a dual-boot option. Start rejoicing now; it's not XP or Sugar (the native, education-centric OS) — it's Sugar or Gnome. And of course there are other homebrew distributions like Xtra Ordinary, built off of Debian."Read more of this story at Slashdot.
Google SideWiki Brings Comments To Everyone
Rophuine writes "Google has launched a product called SideWiki. It takes the form of a plug-in to Firefox and Internet Explorer which allows users to mark up the web by adding comments which can be seen by anyone else running SideWiki." Google's version joins a long line of attempts to impose a layer of comments on the Web, including Microsoft's Smart Tags and Third Voice.Read more of this story at Slashdot.
Wii Gets Price Cut To $199
After watching Microsoft and Sony drop the prices on the Xbox 360 and the PS3, Nintendo has decided to jump in with a price cut as well. Starting September 27th, the Wii will cost $199 in North America, a $50 drop from the previous price. Japan will be getting a slightly smaller price cut, but Europe seems to be left out of this change. Nintendo is hoping this reduction and the release of New Super Mario Bros. Wii and Wii Fit Plus in the coming months will boost slipping sales rates.Read more of this story at Slashdot.
AIDS Vaccine Is Partially Successful
ifchairscouldtalk writes "A Phase III 'RV 144' study in Thailand succeeded in reducing HIV infection rate in trial with 31.2% effectiveness. The study was conducted by the Thailand Ministry of Public Health and used strains of HIV common in Thailand. It is not clear whether the vaccine, which combines AIDSVAX with Aventis Pasteur ALVAC-HIV canarypox vector, known as 'vCP1521,' would work against other strains in the United States, Africa or elsewhere. Strangely, the vaccine had no effect on levels of HIV in the blood of those who did become infected, providing 'one of the most important and intriguing findings' of the trial, according to Dr Fauci, director of the National Institute of Allergy and Infectious Diseases, which is one of the trial's sponsors."Read more of this story at Slashdot.
Google Frame Benchmarks 9x Faster than IE8
ChiefMonkeyGrinder writes "Early tests with Google's Chrome Frame found IE8 runs 9.6 times faster than usual. The testers ran the SunSpider JavaScript benchmark suite." The other question is what is the performance hit of using the Frame plug-in instead of running the browser natively.Read more of this story at Slashdot.
The World's First Four-Screen Laptop
Barence writes "Intel has stunned visitors at IDF by showing off the world's first four-screen laptop. The oddly-named 'Tangent Bay' has three miniature touchscreens set horizontally into the case below the main, full-sized panel. It is a fully functional prototype: delegates were able to scroll photos around the touchscreens by swiping with a finger. The idea smacked a little too much of the ill-fated Vista SideShow." Seems strange that they would put the screens above the keyboard. I think embedding an iPhone type touchscreen in place of the trackpad would be a far more useful thing.Read more of this story at Slashdot.
GPL Wins In French Court Case
viralMeme writes "An appeals court in Paris has upheld the ruling from a lower court, which found that the French firm Edu4 had violated the GNU General Public License (GPL). The plaintiff was the French Organisation Association francaise pour la Formation Professionnelle des Adultes (AFPA), an umbrella organization for adult education." The basic charge was the removal of copyrights and such from VNC source code, and not distributing it.Read more of this story at Slashdot.
