Ask Slashdot: What's the Most Often-Run Piece of Code -- Ever?

Slashdot - Sat, 2014-01-18 17:55
Hugo Villeneuve writes "What piece of code, in a non-assembler format, has been run the most often, ever, on this planet? By 'most often,' I mean the highest number of executions, regardless of CPU type. For the code in question, let's set a lower limit of 3 consecutive lines. For example, is it: A UNIX kernel context switch? A SHA2 algorithm for Bitcoin mining on an ASIC?A scientific calculation running on a supercomputer?A 'for-loop' inside on an obscure microcontroller that runs on all GE appliance since the '60s?"

Solar Lull Could Cause Colder Winters In Europe

Slashdot - Sat, 2014-01-18 16:50
Taco Cowboy writes "Since September of last year scientists have been wondering what's happening to the Sun. It's supposed to have reached the peak of its 11-year cycle, but sunspot and flare activity remains much quieter than expected. Experts now think the recent cold snap that hit North America and the wet weather that hit part of Europe might be linked to the eerie quietness of the Sun. According to the BBC, solar activity hasn't been this low in 100 years, and if activity keeps dropping, it may reach levels seen during the 'Maunder Minimum,' an 'era of solar inactivity in the 17th Century [which] coincided with a period of bitterly cold winters in Europe.' It wouldn't have a big effect on global temperatures, just regional ones. Why? The sun's UV output drops during these lulls, and the decreased amount of UV light hitting the stratosphere would cause the jet stream to change course. Prof. Mike Lockwood says, 'These are large meanders in the jet stream, and they're called blocking events because they block off the normal moist, mild winds we get from the Atlantic, and instead we get cold air being dragged down from the Arctic and from Russia. These are what we call a cold snap... a series of three or four cold snaps in a row adds up to a cold winter. And that's quite likely what we'll see as solar activity declines.'"

Analyst Calls Russian Teen Author of Target Malware

Slashdot - Sat, 2014-01-18 15:48
Nerval's Lobster writes "A digital-activity data analytics firm called IntelCrawler, Inc. claims to have identified the author of the BlackPOS malware used in attacks against Target and Neiman Marcus, and spotted similar attacks that are still in progress against six other retailers. Andrey Komarov, CEO of the Los Angeles-based IntelCrawler, told Reuters Jan. 17 that his company had spotted the six ongoing attacks while analyzing Web traffic in search of the specific entry points and origin of the malware infection behind the Target data breach, which allowed hackers to steak magnetic card-strip data on 40 million debit- and credit cards and demographic data on 70 million additional customers. According to Komarov, BlackPOS was developed by a 17-year-old Russian who goes by the username Ree4 and lives in St. Petersburg. Ree4 probably did not participate in the attack on Target, but did sell the malware to the actual attackers, according to Komarov, who refused to identify the source of his information other than to say he had been monitoring forums on which he said Ree4 sells malware. In a series of chat clips Komarov said are exchanges between buyer and seller, Ree4 tells a potential customer that the price for the software is US$2,000 and that the malware grabs credit-card numbers from system memory as they're scanned, dumps them into a file called time.txt that is sent back to the controller. Ree4 also said the app works only on standalone point-of-sale terminals with a separate monitor that also runs Windows, but not on Verifone systems, which can be attached to PCs but secure credit-card data before it can be scraped by BlackPOS."

Valve Working on GNU/Linux Native Open Source OpenGL Debugger

Slashdot - Sat, 2014-01-18 14:43
jones_supa writes "OpenGL debugging has always lagged behind DirectX, mainly because of the excellent DX graphics debugging tools shipping with Visual Studio and GL being left with APITrace. Valve's Linux initiatives are making game companies to think about OpenGL, and the video game company wants to create a good open source OpenGL debugger to improve the ecosystem. AMD and Nvidia have already expressed interest in helping them out. Valve has been developing VOGL mostly on Ubuntu-based distributions under Qt Creator. The software currently supports tracing OpenGL 1.0 through 3.3 (core and compatibility), and is expected to eventually support OpenGL 4.x. Many more details on VOGL can be found at Valve's Rich Geldreich's blog." This looks much nicer than BuGLe. Valve is using Mercurial for version control and they plan to throw it up on bitbucket under an unspecified open source license soon. It works with clang and gcc, but debugging with gcc is currently very slow (hopefully something that can be fixed once the source is available and the gcc hackers can see what's going on). The tracer's internal binary log format can be converted into JSON for use with other tools as well.

Disk ARchive 2.4.12

Freshmeat - Sat, 2014-01-18 14:28
Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.

Release Notes: This release adds several minor bugfixes, including one for a bug met under a very rare condition leading dar to wrongly report a file as corrupted at reading time, another for a bug in the sparse file detection mechanism which could lead dar to miss detecting small holes in files, several code updates to support compilation in g++11 mode, and other fixes relative to dar compilation within a BSD system like Mac OS X.

What Makes a Genius?

Slashdot - Sat, 2014-01-18 13:40
Hugh Pickens DOT Com writes "Eric Barker writes at TheWeek that while high intelligence has its place, a large-scale study of more than three hundred creative high achievers including Leonardo da Vinci, Galileo, Beethoven, and Rembrandt has found that curiosity, passion, hard work, and persistence bordering on obsession are the hallmarks of genius. 'Successful creative people tend to have two things in abundance, curiosity and drive. They are absolutely fascinated by their subject, and while others may be more brilliant, their sheer desire for accomplishment is the decisive factor,' writes Tom Butler-Bowdon. It's not about formal education. 'The most eminent creators were those who had received a moderate amount of education, equal to about the middle of college. Less education than that — or more — corresponded to reduced eminence for creativity,' says Geoffrey Colvin. Those interested in the 10,000-hour theory of deliberate practice won't be surprised that the vast majority of them are workaholics. 'Sooner or later,' writes V. S. Pritchett, 'the great men turn out to be all alike. They never stop working. They never lose a minute. It is very depressing.' Howard Gardner, who studied geniuses like Picasso, Freud, and Stravinsky, found a similar pattern of analyzing, testing, and feedback used by all of them: 'Creative individuals spend a considerable amount of time reflecting on what they are trying to accomplish, whether or not they are achieving success (and, if not, what they might do differently).' Finally, genius means sacrifice. 'My study reveals that, in one way or another, each of the creators became embedded in some kind of a bargain, deal, or Faustian arrangement, executed as a means of ensuring the preservation of his or her unusual gifts. In general, the creators were so caught up in the pursuit of their work mission that they sacrificed all, especially the possibility of a rounded personal existence,' says Gardner."
