antdude writes "This TechRadar article explains why computers suck at math, and how simple calculations can be a matter of life and death, like in the case of a Patriot defense system failing to take down a Scud missile attack: 'The calculation of where to look for confirmation of an incoming missile requires knowledge of the system time, which is stored as the number of 0.1-second ticks since the system was started up. Unfortunately, 0.1 seconds cannot be expressed accurately as a binary number, so when it's shoehorned into a 24-bit register — as used in the Patriot system — it's out by a tiny amount. But all these tiny amounts add up. At the time of the missile attack, the system had been running for about 100 hours, or 3,600,000 ticks to be more specific. Multiplying this count by the tiny error led to a total error of 0.3433 seconds, during which time the Scud missile would cover 687m. The radar looked in the wrong place to receive a confirmation and saw no target. Accordingly no missile was launched to intercept the incoming Scud — and 28 people paid with their lives.'"

An anonymous reader writes "Brazilian elections went electronic many years ago, with very fast results but a few complaints from losers, of course. Next month, 10 teams that accepted the challenge will have access to hardware and software (Google translation; original in Portuguese) for the amount of time they requested (from one hour to four days). Some will try to break the vote's secrecy and some will try to throw in malicious code to change the entered votes without leaving traces."

GMGruman writes "Every few months, it seems, there is a new 'iPhone killer.' Android 2.0, in the guise of the Motorola Droid, is the latest such 'killer.' But what will it really take to beat or match the iPhone (single page), and does Android or any other mobile OS have the right stuff? There's a lot more to the answer than is usually discussed. This article takes a look at the strengths that may allow Droid and Android 2.0 to provide strong competition to devices like the iPhone and the Blackberry, as well as the obstacles it continues to face that could inhibit adoption."

alphadogg writes "The Conficker worm has passed a dubious milestone. It has now infected more than 7 million computers, security experts estimate. On Thursday, researchers at the volunteer-run Shadowserver Foundation logged computers from more than 7 million unique IP addresses, all infected by the known variants of Conficker. They have been able to keep track of Conficker infections by cracking the algorithm the worm uses to look for instructions on the Internet and placing their own 'sinkhole' servers on the Internet domains it is programmed to visit. Conficker has several ways of receiving instructions, so the bad guys have still been able to control PCs, but the sinkhole servers give researchers a good idea how many machines are infected."

CWmike writes "Users should wait for Microsoft to work out the bugs in Windows 7 before jumping on the new OS, computer support company Rescuecom said on Friday. 'From the calls we're getting, as well as our own experience in the past with all Microsoft's operating systems, we're recommending that people stick with their time-tested OS and wait for the dust to settle,' said Josh Kaplan, president of Rescuecom. Citing a litany of reasons, ranging from the risk of losing data during an upgrade to tough economic times, Kaplan urged Windows users to put off upgrading to Windows 7 or buying a new PC with the operating system pre-installed. 'There are some compelling reasons for both businesses and home users to move to Windows 7,' Kaplan said, 'so we're saying "just wait for a bit."' Upgrading an existing machine — whether it's running the eight-year-old Windows XP or the much newer Vista — is particularly risky, he added, especially if users haven't taken time to make a full backup before they migrate their machines. Some users have found that out first hand. Among the top subjects on Microsoft's support forum is one that has put some PCs into an endless reboot loop when their owners tried to upgrade from Vista to Windows 7. Microsoft has not yet come up with a solution that works for all the users who have reported the problem, sparking frustration."

stoolpigeon writes "The Android 2.0 SDK is now available from Google. This puts to bed concerns about Google not releasing the SDK or perhaps being in some kind of exclusivity deal with Verizon around 2.0. The release notes give a nice overview of what is there. Those who already have the SDK can grab the updated tools as SDK components; everyone else will pick up everything when downloading the new SDK." Relatedly, reader riffzifnab reports that Google has also announced Google Maps Navigation, a GPS application for Android 2.0 that takes voice input and integrates with internet searches and Street View.

An anonymous reader writes "According to the Google blog, it has partnered up with Twitter to bring tweets into its search results in the next few months. While this is exciting news, how the feature is going to present itself is a huge question. Indiblogger presents a comprehensive list of how it should be. From the article, the points discussed are: relevance of tweets with the search term, twitter and Google advertising, even a Google-Twitter API."

jammag writes "Well, c'mon, yes — let's admit it. As a veteran coder discusses as he looks at his career, software development is brimming with the offbeat, the quirky and the downright odd. As he remembers, there was the 'Software Lyrics' guy and the 'Inappropriate Phone Call' programmer, among others. Are unique types drawn to the profession, or are we 'transformed over time by our darkened working environments and exposure to computer screen radiation?'"

caffiend666 writes "'Marge Simpson is posing for Playboy . The magazine is giving the star of The Simpsons the star treatment, complete with a data sheet, an interview and a 2-page centerfold. 'We knew that this would really appeal to the 20-something crowd,' said Playboy spokeswoman Theresa Hennessey. Playboy even convinced 7-Eleven to carry the magazine in its 1,200 corporate-owned stores, something the company has only done once before in more than 20 years." Worst issue ever!

Gi0 writes "After a couple of months of rejection, the C64 Emulator has finally been approved for the iPhone (and is available at the app store now). 'BASIC has been removed for this release; however, we hope that working with Apple further will allow us to re-enable it. Despite its absence, BASIC is not our focus; ultimately, fans of the C64 want games.' It comes with 5 bundled games and will certainly give you that retro fix for your iPhone."

Several sites are reporting on the addition of extra fees to PayPal that are just starting to become common knowledge. While PayPal has certainly had their fair share of controversy, the new "transaction fees" that promise to affect the entire customer base are already well on their way to becoming another. "For example, a personal account sending another personal account money for a one-time payment for, say, mowing your lawn was not previously charged any fees on either side, but is now charged the usual transaction fee (the sender gets to decide who pays). The only way to avoid this is by selecting 'gift' when making the transfer — something you can't do if you're following through on a purchase or invoice from someone. And, if you fall into this category (which many people do), it's likely that you had no idea about the changes until just now."

FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

R.Mo_Robert writes "BetaNews is reporting that Google is acquiring On2, the video codec company and original developers of the VP3 codec from which Theora is derived. The article suggests that this may mean Google is backing Ogg Theora as the HTML5 video standard, but this is likely not the case--with Theora already being open-source and On2 having disclaimed all rights and patents, there is no reason Google should have needed to do this to push Theora. You may recall from some time back that HTML5 no longer specifies which video codec(s) a browser should support due to there being, unfortunately, no suitable codec at this time. But Google (known for supporting H.264) practically owns Web video with YouTube in most people's minds, so their influence could really swing the future of HTML5 video either way. It remains to be seen whether Google's acquisition of On2 has any bearing on their plans for video on the Web."

Groo Wanderer writes "Normally, a well-crafted fake ATM would skim a lot of card information before it was noticed, if it was ever noticed at all. Because it is safer for the criminals and harder to prosecute, financial crimes like this are spreading fast. If you are smart, you don't try to pull one off in the middle of a computer security convention where the attendees are very good at spotting such scams. That said, some not-so-bright criminal tried to plant a fake ATM at Defcon. He now has one less fake ATM and a whole lot of investigators on his tail."
