FreeBSD 8 supports GCD

Robert Watson wrote on the FreeBSD Stable mailing list that FreeBSD 8 now supports Apple’s Grand Central Dispatch:

…may be interested in using Apple’s GCD technology on FreeBSD. GCD, for those who may have missed it, is a concurrent programming framework introdued in Mac OS X Snow Leopard, now also supported on FreeBSD.

There are a number of useful links on the wiki page, but this provides the best high-level introduction.

Support FreeBSD and the FreeBSD Foundation

FreeBSD foundation logoMany people have already donated since my last post about the FreeBSD Foundation‘s end of year fund raising drive.

So far almost 600 people  (and companies) have donated to the FreeBSD Foundation, but the  $300.000 target hasn’t been achieved yet: the counter stands at $166.381.

What does the FreeBSD Foundation do?

We fund and manage projects, sponsor FreeBSD events, Developer Summits and provide travel grants to FreeBSD developers. We provide and help maintain computers and equipment that support FreeBSD development and improvements. We also represent the Project in executing contracts, license agreements, copyrights, trademarks, and other legal arrangements that require a recognized legal entity.

FreeBSD 8.0 has been released now. If you’re a happy FreeBSD user and want to support the development of FreeBSD 9, why not make a (small) donation? More people have donated this year than before. Any amount counts.

Securing Network Services with FreeBSD Jails

In this article by Christer Edwards, we will explore FreeBSD Jails. FreeBSD Jails are a kernel-level security mechanism which allows you to safely segregate processes within a sandbox environment. Jails are commonly used to secure production network services like DNS or Email by restricting what a process can access. In the case of a malicious attack on one service, all other Jailed processes would remain secure. FreeBSD Jails securely limits, in an administratively simple way, the amount of damage an attacker can do to a server.
