The company Coverity, the leader of the automated testing of code for errors and vulnerabilities, gave a report , which is a product of the largest joint public-private project to audit the source code of open and proprietary software. The report contains an analysis of more than 37 million lines of code 45 most actively developing projects with open source software, as well as about 300 million lines of code, an unnamed 41-proprietary software.

Key points of the report:

• The average size of open source software is 832,000 lines of code, with 1,000 lines of code were found on average 0.45 defects.

Late last year I had the opportunity the current consumption of Sandy Bridge systems to reduce significantly. For this, the kernel must be booted with the parameters “acpi = force = pcie_aspm noirq i915.i915_enable_rc6 = 1″. Read all the how, why and why I can save myself here at this point that you can indeed in the linked article. As you can see in the comments to the post that helped you, too good for the bank. What is still missing are concrete data, as well as work, these parameters. This now provides Torben on his blog after. He has experimented with a bit of the kernel parameters and summarized the results in meaningful charts.

The organization Electronic Frontier Foundation is pleased to announce that an illegal action, threatening the important basis of time zones, was rejected. Astrolabe Company also apologized and agreed not to file such claims in the future that will help protect the tz database, against unreasonable lawsuits and failures.

Software developers around the world rely on the basis of time zones, to ensure that the timestamp of e-mails and other files are working correctly, no matter where you are. However, in September last year filed a lawsuit against the Astrolabe Arthur David and Paul Eggert Oslon – researchers who coordinate the development of tzdata for decades, because the database contains information from the atlas, which makes the company copyrights. But the facts – for example, that the sun rises – may not be subject to copyright.
