At ELC Europe, Linux kernel developer Laurent Pinchart unveiled a follow-on to the V4L2 stack for embedded cameras.

With apologies to Arnold and the Terminator franchise for the title, let's look one more time at removing duplicates from the PATH variable. This take on doing it was prompted by a comment from a reader named Shaun on the previous post that asked "if you're willing to use a non-bash solution (AWK) to solve the problem, why not use Perl?" Shaun was kind enough to provide a Perl version of the code, which was good, since I'd have been hard-pressed to come up with one. It's a short piece of code, shorter than the AWK version, so it seemed like it ought to be fairly easy to pick it apart. In the end, I'm not sure I'd call it easy, but it was interesting, and I thought other non-Perl programmers might find it interesting too.

If you strip away all of the modern conveniences and features that make up your internet experience today, what you're left with is the client-server model. This distributed network was what the internet was built on in the beginning, and that part hasn't changed. You could say, it is still serving us well.

Of course not: That "client-server model" is still the backbone of how things are getting done. read more

Leadership works differently at Red Hat. In our open organization, people don't just receive the status of "leader" when appointed to a position or given a title. Instead, leaders earn their leadership positions when they adopt a certain combination of behaviors and mindsets. read more

Another kernel dev is “unfscking” the source code, with predictable results Linus Torvalds has stuck to his “no swearing” resolution with his regular Sunday night release candidate announcement.

When did open source begin? In February 1998, when the term was coined by Christine Peterson? Or in 1989, when Richard Stallman drew up the "subroutinized" GNU GPL? Or perhaps a little earlier, in 1985, when he created the GNU Emacs license? How about on March 6, 1665? On that day, the following paragraph appeared...

You can share NFS home directories without enabling Kerberos for more secure authentication. But with the standard system authentication, it’s trivial for a remote user to change the UID of a local account on their PC and gain access to someone else’s home directory. Kerberos adds a requirement that the end user have a special […]
