The Linux Foundation has long offered a wide variety of training courses through its website, but those can generally cost upwards of $2,000. This introductory class, which usually costs $2,400, will be the first from the Linux Foundation to run as a Massive Open Online Course (MOOC)."

First time accepted submitter liquiddark writes "I was listening to a younger coworker talk to someone the other day about legacy technologies, and he mentioned .NET as a specific example. It got me thinking — what technologies are passing from the upstart and/or mainstream phases into the world of legacy technology? What tech are you working with now that you hope to retire in the next few years? What will you replace it with?"

McGruber writes "Austin ranks number one in the nation when it comes to offering the largest tech salaries that have been adjusted for cost of living expenses, such as housing, groceries, utilities and other necessities. This is according to a study by TriNet, a company I had never heard off, that provides (buzzword alert!) cloud-based human resources services. The seven major tech hubs, ranked by cost of living adjusted average salaries: 1. Austin: $105,000; 2. Atlanta: $103,000; 3. Denver-Boulder: $98,000; 4. Boston: $79,000; 5. Silicon Valley: $78,000; 6. Los Angeles: $70,000; 7. New York: $56,000." It's true that Austin has cheaper real estate than Silicon Valley, or London, but what this kind of analysis can't capture well is the worth for an individual of living in a particular place. Some jobs are easier to do from Texas (or Timbuktu) than others, and opinions vary wildly about the importance of climate, culture, alternative job options, and other factors. New York living is expensive, Yes, but it comes with a free bonus if New York is where you want to be. Some people even like Los Angeles. Is there a place you'd rather be but forgo because of the cost of living, or a place you'd consider simply because it would amplify your salary?

jones_supa writes "Valve has recently released Portal 2 on Steam for Linux and opened a GitHub entry to gather all the bugs from the community. When one of the Valve developers closed a bug related to Portal 2 recommending that the users disable a security feature, the Linux community reacted. A crash is caused by the game's interaction with SELinux, the Linux kernel subsystem that deals with access control security policies. Portal 2 uses the third-party Miles Sound System MP3 decoder which, in turn, uses execheap, a feature that is normally disabled by SELinux. Like its name suggests, execheap allows a program to map a part of the memory so that it is both writable and executable. This could be a problem if someone chose to use that particular memory section for buffer overflow attacks; that would eventually permit the hacker to gain access to the system by running code. In the end, Valve developer David W. took responsibility of the problem: 'I apologize for the mis-communication: Some underlying infrastructure our games rely on is incompatible with SELinux. We are hoping to correct this. Of course closing this bug isn't appropriate and I am re-opening it.' This is more of an upstream problem for Valve. It's not something that they can fix directly, and most likely they will have to talk with the Miles developers and try to repair the problem from that direction."
