Back when DragonFlyBSD's HAMMER2 file-system development began being publicized, it was believed it wasn't going to be ready until at least 2013. Fast forward two years, HAMMER2 isn't yet used by default on this BSD operating system and it's still being actively developed.
As we haven't heard much about HAMMER2 in quite some times, I was looking through the DragonFlyBSD HAMMER2 Git commits and happy to see this BTree-based file-system succeeding the original HAMMER FS is still being pursued. HAMMER2 has shipped in DragonFlyBSD since version 3.8.0 but is not considered production ready.
While DragonFlyBSD 4.0.2 was released just two weeks ago, the v4.0.3 update is now out.
DragonFlyBSD 4.0.3 is being released today primarily for an OpenSSL upgrade to bump the version to OpenSSL 1.0.1. Besides upgrading to OpenSSL 1.0.0., there's various fixes for the distribution's HAMMER file-system, various resource/memory leak fixes, and a handful of other bug-fixes.
More details on DragonFlyBSD 4.0.3 can be found via this tagging message. Download this longtime forked FreeBSD operating system from DragonFlyBSD.org.
Besides working toward PC-BSD 10.1.1's release, the PC-BSD crew have also been working on improving their Lumina Desktop Environment.
Nearly a year ago I wrote about PC-BSD developing its own desktop environment and months later it was out in alpha form. The new PC-BSD desktop is called Lumina and it's a homegrown environment catered toward the BSDs. The Lumina desktop is FreeDesktop.org/XDG-complaintand they're hoping for it to be an alternative to GNOME or KDE.
The PC-BSD crew that base their desktop-focused BSD operating system off of FreeBSD put out their 10.1.1. release candidate this week.
This quarterly update to PC-BSD (v10.1.1) is set to bring a new system updater that supports automatic background updating, improvements to the boot environments / GRUB support, GPT partition installation improvements, all PC-BSD desktop utillities have been converted to Qt5, OVA files for virtual machines, and various other improvements over the original PC-BSD 10.1 release.
At MakeUseOf, we cover Linux quite a bit as the “alternative” to Windows and Mac OS X. However, those aren’t the only three operating systems out there — there’s also the BSD family of Unix-like operating systems, which are technically speaking different from Linux.
In the name of fair competition, it’s time that we gave BSD operating systems some recognition as well. And there’s no better way to do that than to compare them against Linux. What’s different about BSD operating systems, and should you be running it instead of Linux? How does Linux and the best BSD desktop OS, PC-BSD, compare on the desktop?
Users of DragonFlyBSD on the desktop (or otherwise using sound on this popular BSD platform) will benefit from the next major update of the operating system.
DragonFlyBSD has pulled in the sound system from the FreeBSD 11 development code and it offers a huge improvement over the previous code, which was from FreeBSD 6.x.
With this new sound system update there's smarter volume controls, improved HDMI/DisplayPort audio, an easy way to switch the default sound device, and HTML5/YouTube videos should now play with sound out-of-the-box. There's also new hardware support with this new sound update.
Among the pros of ZFS are it's self-healing, writable clones, fully journaling system using ZFS snapshots, compression, and portable storage. Among the viewed HAMMER positives are the focus on data integrity, great SQL database performance, lower RAM requirements, supports pseudo file-systems, fully open-source with a BSD license, etc. Of course, with each also comes various cons.
