Has the NSA broken SSL? TLS? AES?

Just how broken are fundamental Internet security technologies such as Secure-Socket Layer (SSL), Advanced Encryption Standard (AES), and Transport Layer Security (TLS)? We still don’t know for certain. But, it’s clear that the National Security Agency (NSA) has broken many kinds of  Internet encryption technologies… including the ones we use every day.

Linux Professional Institute puts Linux in the classrooms

Do you want a job in IT? Then you really need to learn Linux and open-source software.

When I was at the open-source OSCon convention earlier this year,  everyone, and I mean everyone, including Microsoft, was looking to hire people with Linux and open-source experience. A recent Dice and Linux Foundation survey found that 93 percent of employers were looking to hire Linux staffers in the next six months and that 90 percent were having trouble finding qualified individuals.

Wearable computing: Why there’s no room for watches like Galaxy Gear

Graying Linux developers look for new blood

It’s not that Linux’s core developers are “old.” After all, Linus Torvalds, Mr. Linux himself, is only 42. But for a few years now, the core Linux kernel developers have been aware that the top programmers have been getting older.

This isn’t just an impression. While as Amanda McPherson, The Linux Foundation‘s VP of marketing and developer programs, told me that “participation in Linux is greater than ever before” and that “more than 8,000 people had contributed to the Linux kernel since 2005,” a closer look at the Linux developer numbers reveals that the older generations of Linux programmers are fading away.
