The Best Burglar Alarm In History 137

Sportsqs writes "When Nikola Tesla got creative with transformers and driver circuits at the turn of the 20th century he probably had no idea that others would have so much fun with his concepts over a hundred years later. One such guy is an Australian named Peter who runs a website called TeslaDownUnder, which showcases all his wacky Tesla ways, or rather electrickery, as Peter calls it." Very cool stuff, I wish I would have had something like this to protect my comic books from my little brother when I was a kid.
It's funny.  Laugh.

Unix Dict/grep Solves Left-Side-of-Keyboard Puzzle 423

destinyland writes "For decades, people have been asking this brain teaser: 'What's the longest word you can type with only the left-hand letters on a keyboard?' The answer is supposed to be 'stewardesses,' but grepping the standard dictionary that ships with Unix reveals a much better answer. There's nearly 2,000 shorter words that can typed with only the left hand — including one word that's even longer. (The article also quotes a failed novel attempt using nothing but words typed on the keyboard's left side.)"

The Effects of the Cloud On Business, Education 68

g8orade points out two recent articles in The Economist about the rise of cloud computing. The first discusses how software-as-a-service has come to pervade online interactions. "Irving Wladawsky-Berger, a technology visionary at IBM, compares cloud computing to the Cambrian explosion some 500m years ago when the rate of evolution sped up, in part because the cell had been perfected and standardised, allowing evolution to build more complex organisms." The next article examines how the cloud will force a "trade-off between sovereignty and efficiency." Reader pjones contributes news that the Virtual Computer Lab will be supplementing more traditional computer labs at North Carolina State University, and adds, "NCSU's Virtual Computing Lab and IBM are offering the VCL code as a software 'appliance' for use in schools to link to the program. Downloads are available at ibiblio at UNC-Chapel Hill. The VCL also is partnering with Apache.org to make the software available and to allow further community participation in future development."

Why RAID 5 Stops Working In 2009 803

Lally Singh recommends a ZDNet piece predicting the imminent demise of RAID 5, noting that increasing storage and non-decreasing probability of disk failure will collide in a year or so. This reader adds, "Apparently, RAID 6 isn't far behind. I'll keep the ZFS plug short. Go ZFS. There, that was it." "Disk drive capacities double every 18-24 months. We have 1 TB drives now, and in 2009 we'll have 2 TB drives. With a 7-drive RAID 5 disk failure, you'll have 6 remaining 2 TB drives. As the RAID controller is busily reading through those 6 disks to reconstruct the data from the failed drive, it is almost certain it will see an [unrecoverable read error]. So the read fails ... The message 'we can't read this RAID volume' travels up the chain of command until an error message is presented on the screen. 12 TB of your carefully protected — you thought! — data is gone. Oh, you didn't back it up to tape? Bummer!"

Getting Hired As an Entry-Level Programmer? 540

An anonymous reader writes "I received a state university degree in Computer Science. After graduation, I immediately took jobs in QA to pay the bills while waiting for other opportunities, which of course turned out to be as naive as it sounds. I've been working QA for several years now and my resume does not show the right kind of work experience for programming. On the whole I'm probably no better as a a candidate than a CS graduate fresh out of college. But all of the job postings out in the real world are looking for people with 2-5 years of programming work experience. How do you build up those first 2 years of experience? What kinds of companies hire programmers with no prior experience?"

Fast-Booting Text-Editor Operating System? 660

cgenman writes "What is the fastest booting operating system out there that is still sufficient for editing text? Quite frequently, I'll need to boot my laptop and edit a few lines of text, or jot down an idea or two. XP loads in roughly 4 minutes to usable, and Ubuntu loads in about 60 seconds. Both feel like an eternity if there isn't a pen and paper around. What is the best operating system that people have found which would load to useable in under 20 seconds, can edit text files in something a little more friendly than VI or EMACS, yet can still access fat32 formatted USB drives? GUIs aren't required, but commands which require arcane foreknowledge or a cheat sheet are out."

Trading the Markets With FOSS Software? 417

Robert writes "Along with many other techies, I share an interest in the world of finance (bubble-era stock options pulled me in). Unfortunately, as someone with a strong preference for GNU/Linux as my operating system of choice, I have found that software in this area seems quite sparse. For awhile I have made do with Python, R, Gnumeric, Gnucash and a telephone, along with some small utilities I have written myself. What I would like to know is: what FOSS software do you use for financial analysis, trading, system development, and testing in a Un*x environment? Are there programs you would like to see written or ported? Do any brokerages, data providers, or other services provide good support for we the few? And finally, what commercial entities do you know of that are using FOSS software in their operation?"

Should Organic Chemistry Be a Premed Requirement? 567

1-quack-4-malpractice writes "For the second time, the Wall Street Journal health blog has questioned whether premed students should be forced to suffer through organic chemistry. Dozens of doctors weighed in with comments, and many of them seem to think that the wry subject is an almost useless rite of passage. Wired Science points out that there are not enough doctors who do research in addition to seeing patients, and they are the ones who benefit most from a thorough grounding in basic sciences like organic chemistry."

Intel Shows Data Centers Can Get By (Mostly) With Little AC 287

Ted Samson IW writes "InfoWorld reports on an experiment in air economization, aka 'free cooling,' conducted by Intel. For 10 months, the chipmaker had 500 production servers, working at 90 percent utilization, cooled almost exclusively by outside air at a facility in New Mexico. Only when the temperature exceeded 90 degrees Fahrenheit did they crank on some artificial air conditioning. Intel did very little to address air-born contaminants and dust, and nothing at all to deal with fluctuating humidity. The result: a slightly higher failure rate — around 0.6 percent more — among the air-cooled servers compared to those in the company's main datacenter — and a potential savings of $2.87 million per year in a 10MW datacenter using free cooling over traditional cooling."

Ray Beckerman Sued By the RIAA 725

An anonymous reader writes "Ray Beckerman, known for questioning the RIAAs legal tactics (also for frequent Slashdot contributions), was sued by the RIAA over his blog Recording Industry vs. People. In question is the 'vexatious' claims that the RIAAs legal tactics is a 'sham.' Beckerman is quoted as saying that the litigation against him is 'frivolous and irresponsible.'"

Software Spots Spin In Political Speeches 438

T.S. Ackerman writes "According to an article in NewScientist Tech, there is now software that can identify the amount of spin in a politician or candidate's speech. From the article, 'Blink and you would have missed it. The expression of disgust on former US president Bill Clinton's face during his speech to the Democratic National Convention as he says "Obama" lasts for just a fraction of a second. But to Paul Ekman it was glaringly obvious. "Given that he probably feels jilted that his wife Hillary didn't get the nomination, I would have to say that the entire speech was actually given very gracefully," says Ekman, who has studied people's facial expressions and how they relate to what they are thinking for over 40 years.' The article goes on to analyze the amount of spin in each of the candidates running for president, and the results are that Obama spins the most."
