Does Typing Speed Really Matter For Programmers? 545

Posted by timothy from the backspace-speed-is-key dept.
theodp writes "I can't take slow typists seriously as programmers,' wrote Coding Horror's Jeff Atwood last fall. 'When was the last time you saw a hunt-and-peck pianist?' Atwood's rant prompted John Cook to investigate just how important it is to be able to type quickly. 'Learning to type well is a good investment for those who are physically able to do so,' concludes Cook, 'but it's not that important. Once you reach moderate proficiency, improving your speed will not improve your productivity much. If a novelist writing 1000 words per day were able to type infinitely fast, he or she could save maybe an hour per day.' At 150 WPM, notes Cook, the world's fastest typist was still only 10x faster than Stephen Hawking."

RubyGems' Module Count Soon To Surpass CPAN's 206

Posted by timothy from the we-finally-know-who's-counting dept.
mfarver writes "According to the data gathered by modulecounts.com, the total number of modules checked into RubyGems (18,894, and growing at about 27/day) will probably exceed CPAN (18,928, and growing about 8/day) this week."

The Case For Lousy Passwords 343

Posted by CmdrTaco from the love-for-the-lousy dept.
itwbennett writes "Since the Gawker and McDonald's hack attacks, the web has been overrun with admonishments against using weak passwords. But weak passwords have their place too, says blogger Peter Smith. Like, for example, on Gawker, where he really doesn't care if it gets cracked. 'Life is too short to be worrying about 24 character passwords for trivial sites,' says Smith. And, to put things in perspective, your good passwords are pretty weak too. In a 2007 Coding Horror article, Jeff Atwood points out that the password "Fgpyyih804423" was cracked in 160 seconds by the Ophcrack cracker."

With the Jack PC, the Computer's In the Wall! 119

Posted by CmdrTaco from the that's-pretty-sweet dept.
cylonlover writes "The Jack PC from Chip PC Technologies offers a neat and novel thin-client desktop computing solution where the computer doesn't just plug into the wall, it is the plug in the wall. Running on power provided by the ethernet cable that also connects it to the data center server, the computer-in-a-wall-socket supports wireless connectivity, has dual display capabilities and runs on the RISC processor architecture."

W3C Says IE9 Is Currently the Most HTML5 Compatible Browser 382

Posted by Soulskill from the complain-about-the-tests-here dept.
GIL_Dude writes "The W3C posted results for their latest HTML5 compatibility tests and have found that, so far, IE 9 has the best overall results. 'The tests cover seven aspects of the spec: "attributes," "audio," "video," "canvas," "getElementsByClassName," "foreigncontent," and "xhtml5." The tests do not yet cover web workers, the file API, local storage, or other aspects of the spec. Not do they cover CSS or other standards that have nothing to do with HTML5 but are somehow lumped under HTML5 by the likes of Apple, Google, and Microsoft.'"

Taco Bell Programming 394

Posted by timothy from the how-dare-you-insult-the-code-monkeys dept.
theodp writes "Think outside the box? Nah, think outside the bun. Ted Dziuba argues there's a programming lesson to be learned from observing how Taco Bell manages to pull down $1.9 billion by mixing-and-matching roughly eight ingredients: 'The more I write code and design systems, the more I understand that many times, you can achieve the desired functionality simply with clever reconfigurations of the basic Unix tool set. After all, functionality is an asset, but code is a liability. This is the opposite of a trend of nonsense called DevOps, where system administrators start writing unit tests and other things to help the developers warm up to them — Taco Bell Programming is about developers knowing enough about Ops (and Unix in general) so that they don't overthink things, and arrive at simple, scalable solutions.'"

Erm... yes, that's great and all. Except Hatsune Miku has been around since 2007, and versons of the the Vocaloid software that powers "her" has been around a good bit longer (since 2004 or so, I think). I'm pretty sure I heard reference to special-effects-heavy concerts more than a year ago.

Precisely. Japan's latest rock star is a discovery of the Whitman Campaign. Jerry Brown knows what I'm talkin' 'bout.

UK To Track All Browsing, Email, and Phone Calls 286

Posted by samzenpus from the that-about-covers-it dept.
Sara Chan writes "The UK government plans to introduce legislation that will allow the police to track every phone call, email, text message and website visit made by the public. The information will include who is contacting whom, when and where and which websites are visited, but not the content of the conversations or messages. Every communications provider will be required to store the information for at least a year."

At Commonwealth Games, the World's Largest Aerostat 76

Posted by timothy from the more-interesting-than-the-sports dept.
GillBates0 writes "Last weekend saw the world's largest aerostat of its kind featured at the opening ceremony of the 2010 Commonwealth Games in Delhi. The helium balloon or aerostat measures 40x80x12 meters, contains 20,000 cubic meters of helium and features lights, mirrors, cameras, a 360 degree projection screen, projectors and a reflective underbelly. During the show, it was raised 25 meters off the ground and transformed into a giant Bodhi Tree and a meditating Buddha, with giant puppets to complement the cultural performances beneath. These slideshows tell the story."

Submission + - How Well Will Linux Handle Future Multicores? (mit.edu)

Submitted by eldavojohn
eldavojohn writes: Multicore (think tens or hundreds of cores) will come at a price for current operating systems. A team at MIT found that as they approached 48 cores their operating system slowed down. After activating more and more cores in their simulation, a sort of memory leak occurred whereby data had to remain in memory as long as a core might need it in its calculations. But the good news is that in their paper (PDF), they showed that for at least several years Linux should be able to keep up with chip enhancements in the multicore realm. To handle multiple cores, Linux keeps a counter of which cores are working on the data. As a core starts to work on a piece of data, Linux increments the number. When the core is done, Linux decrements the number. As the core count approached 48, the amount of actual work decreased and Linux spent more time managing counters. But the team found that 'Slightly rewriting the Linux code so that each core kept a local count, which was only occasionally synchronized with those of the other cores, greatly improved the system's overall performance.' The researchers caution that as the number of cores skyrockets, operating systems will have to be completely redesigned to handle managing these cores and SMP. After reviewing the paper, one researcher is confident Linux will remain viable for five to eight years without need for a major redesign.

Everything You Need To Know About USB 3.0 322

Posted by timothy from the it-goes-one-louder dept.
Esther Schindler writes "After a lengthy gestation period, the third generation of the Universal Serial Bus is making its way to the market. USB 3.0, also known as SuperSpeed USB, has throughput of up to 5 gigabits per second. That's even faster than the 3Gb/sec of SATA hard drives and 1Gb/sec of high-end networking in the home. USB 3.0: Everything You Need to Know goes into plenty of the techie details. But is it already obsolete — will LightPeak make USB 3.0 irrelevant?"

How To Index and Search a Video By Emotion Screenshot-sm 76

Posted by timothy from the black-beauty-special dept.
robotsrule writes "Here's a a demonstration video of EmoRate, a software program that uses the Emotiv 14-electrode EEG headset to record your emotions via your facial expressions. In the video you'll see EmoRate record my emotions while I watch a YouTube video, then index that video by emotion, and then navigate that video by simply by remembering a feeling. The web page for EmoRate explains how I used Emotiv's SDK to build the software program, and how I trained the system by watching emotionally evocative videos on YouTube while wearing the headset."
