Thanks to Jakob's work on Sparcv9 ABI in Clang and recent changes to Sparc code generator, I am happy to announce that Clang can self host itself on Linux/Sparc64 and on FreeBSD/Sparc64.
This is a feature-focused release. New features: * ssh(1), sshd(8): Add support for key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein's Curve25519. This key exchange method is the default when both the client and server support it.
Linux isn't the only open-source operating system, and it isn't the only one with both server and desktop components either. The FreeBSD Project is one of the earliest open-source operating system projects, with roots connecting it to the original open-source BSD Unix work performed at the University of California at Berkeley. On Jan. 20, FreeBSD 10 debuted, providing server users with multiple performance and virtualization improvements. While FreeBSD itself could potentially be used as a desktop system, the PC-BSD open-source project is the home base for FreeBSD as a desktop operating system.
With FreeBSD 10.0 having been released and the final release of the PC-BSD 10.0 coming this week, I decided to try out the PC-BSD 10.0-RC5 ahead of the final release. While I intended to run some benchmarks of FreeBSD/PC-BSD 10.0 against its predecessor and compared to Linux distributions, this initial PC-BSD 10.0 encounter was cut short after about ten minutes.
“To all of you who have donated, please allow me to give you a huge ‘thank you’,” OpenBSD developer Bob Beck wrote here. “We have in one week gone from being in a dire situation to having a commitment of approximately $100,000 in donations to the Foundation.”
It looks like there's finally going to be stable point releases of the LLVM compiler infrastructure for pushing out bug-fixes quicker, whether you're using the Clang C/C++ compiler or depending upon LLVM for your GPU driver compiler back-end.
FreeBSD 10.0 uses Clang as the default compiler in place of GCC, TRIM support is available for SSDs with ZFS as are other ZFS file-system improvements, AMD Radeon KMS driver support, and a wide-range of packages have been updated. I have already written at length about the best FreeBSD 10 features and other interesting features so check out the dozens of FreeBSD 10.0 articles on Phoronix for more information.
OpenBSD is important because it’s widely used in firewalls, other edge servers, email, DNS and intrusion detection servers for its security. It’s also included in a number of popular third-party packages that include SQL Lite, BIND, Sendmail and the Lynx web browser. ®
OpenBSD supports a wide range of hardware architectures, and for practical and logistical reasons there are few places in the world that have them all in one place except OpenBSD headquarters, see eg this picture, which shows a subset of the machines involved in building OpenBSD releases.
