How To Hire a Hacker
itwbennett writes "If you want to hire a hacker, you need to take a more psychology-based approach to the entire interview process to determine whether he or she has changed their ways enough to be a trustworthy employee, says Mich Kabay in a recent Network World blog post. But this approach is also 'germane for highly skilled staffers, even those that don't come with arrest records or who have done something questionable in their pasts,' says David Strom. For example, in your next interview, ask a question that will suss out how much of a sense of entitlement a candidate has — or how much you or your company has. 'One time when I interviewed with Microsoft in Redmond I couldn't get over this sense of corporate entitlement — it was one of the biggest turn-offs that I had during my interviewing day there,' says Strom. 'I got the feeling that I wasn't going to fit in, no matter how smart I thought (or they thought) I was.'"Read more of this story at Slashdot.
Happy Birthday, Internet!
NobodyExpects writes "I'd like to wish a happy birthday to the Internet! Today marks its 40th birthday! In fall 1969, computers sending data between two California universities set the stage for the Internet, which became a household word in the 1990s. On September 2nd 1969, in a lab at the University of California, Los Angeles, two computers passed test data through a 15-foot gray cable. Stanford Research Institute joined the fledgling ARPANET network a month later; UC Santa Barbara and the University of Utah joined by years end, and the internet was born."Read more of this story at Slashdot.
Sending Astronauts On a One-Way Trip To Mars
The Narrative Fallacy writes "Cosmologist Lawrence M. Krauss, director of the Origins Initiative at Arizona State University, writes in the NY Times that with the investment needed to return to the moon likely to run in excess of $150 billion and the cost of a round trip to Mars easily two to four times that, there is a way to reduce the cost and technical requirements of a manned mission to Mars: send the astronauts on a one way trip. 'While the idea of sending astronauts aloft never to return is jarring upon first hearing, the rationale for one-way trips into space has both historical and practical roots,' writes Krauss. 'Colonists and pilgrims seldom set off for the New World with the expectation of a return trip.' There are more immediate and pragmatic reasons to consider one-way human space exploration missions including money. 'If the fuel for the return is carried on the ship, this greatly increases the mass of the ship, which in turn requires even more fuel.' But would anyone volunteer to go on such a trip? Krauss says that informal surveys show that many scientists would be willing to go on a one-way mission into space and that we might want to restrict the voyage to older astronauts, whose longevity is limited in any case.

First Hot-Ice Computer Created
KentuckyFC writes "Sodium acetate is the stuff inside chemical handwarmers that emits heat when it crystalizes after you press that little metal widget. That's why it is known as hot ice. Now a computer scientist in the UK has created a computer made entirely out of hot ice. The device processes information by exploiting the movement and interaction of wavefronts of crystallisation as they move through the material. The data input is in the form of metal wires that trigger crystal nucleation. The output works by reading off the direction of the moving wavefronts and the edges of the resulting crystals. The researcher has created AND and OR gates and solved a few problems such as finding the shortest path through mazes. There are even a few videos of the computer in action. The resulting computer is far from perfect, however. The data readout sometimes gives no solution and at other times gives circular results, the hot ice equivalent of a BSOD."Read more of this story at Slashdot.
Microsoft Pushes For Single Global Patent System
Xerolooper writes "What would the world be like if everyone could enjoy the same patent system we use in the USA? From the article: 'A senior lawyer at Microsoft is calling for the creation of a global patent system to make it easier and faster for corporations to enforce their intellectual property rights around the world.' They have already attracted opposition from the open-source community and the Pirate Party. According to the article, the World Intellectual Property Organization (WIPO) will be meeting in Geneva on the 17th and 18th of September."Read more of this story at Slashdot.
All Humans Are Mutants, Say Scientists
Hugh Pickens writes "In 1935, JBS Haldane, one of the founders of modern genetics, studied a group of men with the blood disease hemophilia and speculated that there would be about 150 new mutations in each human being. Now BBC reports that scientists have used next generation sequencing technology to produce a far more direct and reliable estimate of the number of mutations by looking at thousands of genes belonging to two Chinese men who are distantly related, having shared a common ancestor who was born in 1805. To establish the rate of mutation, the team examined an area of the Y chromosome which is unique because, apart from rare mutations, the Y chromosome is passed unchanged from father to son so mutations accumulate slowly over the generations. Despite many generations of separation, researchers found only 12 differences among all the DNA letters examined. The two Y chromosomes were still identical at 10,149,073 of the 10,149,085 letters examined."Read more of this story at Slashdot.
Will You Stream Or Download Your Mobile Music?
mikp writes "In a David-and-Goliath style fight, small music companies are battling it out with established behemoths to see who can own the future of mobile music. Spotify, the Europe-based music streaming company, is about to launch its iPhone app and has plans to develop it for other mobile platforms soon. In a preview, Spotify shows how you can cache songs to your iPhone so that you don't always need a connection but the songs don't remain on your iPhone permanently. Nokia, on the other hand, has just announced two more music phones that will feature Comes With Music, an unlimited music-download service that involves a one time fee, which is part of the price of the CWM phone, and lets you download music for free (and you get to keep it) for a year. The question remains, are people more likely to stream or download music on their mobile phones?"Read more of this story at Slashdot.
Coders At Work
Vladimir Sedach writes "Aside from authoring narrowly focused technical books, teaching university courses, or mentoring others in the workplace, programmers don't often get a chance to pass on the knowledge of the practise of programming as a profession. Peter Seibel's Coders at Work takes fifteen world-class programmers and distills their wisdom into a book of interviews with each of them." Keep reading for Vladimir's review.Read more of this story at Slashdot.
Game Over For Sony and Open Source?
Glyn Moody writes "Sony has never been much of a friend to hackers, and its infamous rootkit showed what it thought of users. But by omitting the option to install GNU/Linux on its new PS3, it has removed the final reason for the open source world to care about Sony. Unless, of course, you find Google's new distribution alliance with Sony to pre-install Chrome on its PCs exciting in some way."Read more of this story at Slashdot.
Major ISPs Seek To Lower Broadband Definition
denobug sends word that major internet service providers in the US are seeking to redefine the term 'Broadband' to mean a much lower speed than in other developed nations. In recent filings with the FCC, Comcast and AT&T both came out in support of a reduced minimum speed. 'AT&T said regulators should keep in mind that not all applications like voice over internet protocol (VoIP) or streaming video, that require faster speeds, are necessarily needed by unserved Americans.' On the other hand, Verizon argued to maintain the status quo, saying that 'It would be disruptive and introduce confusion if the commission were to now create a new and different definition.' A public interest group called Free Press also filed comments with the FCC, recommending that the bar should be set significantly higher, and evolve in a way that corresponds with technological improvements.Read more of this story at Slashdot.
Running Over Virtual Pedestrians Helps In-Game Ad Recall
neuroworld writes to point out a study which found a correlation between in-game violence and a player's ability to recall advertisements seen while playing. The test subjects were given two versions of a driving game, which included "unobtrusive" billboard ads, and their eye movements were recorded by a camera. One version had players hitting targets for points, and the other version had them running down pedestrians. "[The researchers] found ads displayed along with violent scenes to be more memorable to players than those shown with nonviolent content, even though players spent less time looking at them. The results are contrary to expectations stemming from research on television, where violence has been shown to decrease attention to advertisements."Read more of this story at Slashdot.
Astronomers Find the Calmest Place On Earth
The Narrative Fallacy writes "Live Science reports that astronomers in search of the perfect site to take pictures of the heavens have combined data from satellites, ground stations and climate models in a study to assess the many factors that affect image quality — cloud cover, temperature, sky-brightness, water vapor, wind speeds and atmospheric turbulence. They have pinpointed the coldest, driest, calmest place on earth, known simply as Ridge A, 13,297 feet high on the Antarctic Plateau. 'It's so calm that there's almost no wind or weather there at all,' says study leader Will Saunders, of the Anglo-Australian Observatory. 'The astronomical images taken at Ridge A should be at least three times sharper than at the best sites currently used by astronomers.' Located within the Australian Antarctic Territory, the site is 89 miles from the PLATO (PLATeau Observatory) international robotic observatory. The new site would be superior to the best existing observatories on high mountain tops in Hawaii and Chile, Saunders says. 'Because the sky there is so much darker and drier, it means that a modestly-sized telescope would be as powerful as the largest telescopes anywhere else on earth.'"Read more of this story at Slashdot.
Firefox 4.0 Goes Chrome, New UI In Q4 2010
sv_libertarian writes "Mozilla recently updated its product roadmap through 2010. According to the first draft, the current browser will see a minor update in Q4 2009 and another in Q2 2010. Version 4.0 is headed for an October or November 2010 release and will bring a new user interface and browser sync integration. 'There is not much information on how this new user interface will look like, but the first mockups that have been posted on Mozilla's website suggest that the Mozilla team favors a Google Chrome-like design that integrates Windows 7 graphics features. Overall, window elements seem to be floating over the background.' The mockup page emphatically notes that the design is not final."Read more of this story at Slashdot.
Build Your Own $2.8M Petabyte Disk Array For $117k
Chris Pirazzi writes "Online backup startup BackBlaze, disgusted with the outrageously overpriced offerings from EMC, NetApp and the like, has released an open-source hardware design showing you how to build a 4U, RAID-capable, rack-mounted, Linux-based server using commodity parts that contains 67 terabytes of storage at a material cost of $7,867. This works out to roughly $117,000 per petabyte, which would cost you around $2.8 million from Amazon or EMC. They have a full parts list and diagrams showing how they put everything together. Their blog states: 'Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us.'"Read more of this story at Slashdot.
Serious Design Failure At USAspending.gov?
theodp writes "Over at Intelligent Enterprise, Seth Grimes declares the Federal Government's USAspending.gov website a travesty, calling it 'almost a parody of a government-transparency site.' Among the faults cited by Grimes is a botched 'Federal Spending FY 2009 YTD' pie chart that graced USAspending.gov's home page. Not only were the sizes of pie segments not in proportion to the percentage labels (due to a Google Chart API error), the colors in the pie chart didn't even match the colors and values in the table immediately below the chart. Lucky for the Feds, Grimes didn't get a chance to look behind the curtain at the Federal IT Dashboard, where they forgot to remove a (commented) reference to a Google spreadsheet that states 'These totals are pretty poor numbers' (Google workbook). Oops!"Read more of this story at Slashdot.
