The Linux Foundation announced its 2016 event calendar, and issued a CFP for the Apr. 4-6 Embedded Linux Conference, which features an OpenIoT Summit.
It’s once again time to check your calendar to see if you can carve out a few days to network with your geeky peers — the Linux Foundation has revealed its extensive lineup of 2016 events. In 2015, LF events attracted “nearly 15,000 developers, maintainers, sysadmins, thought leaders, business executives and other industry professionals from more than 3,100 organizations across 85 countries,” says the nonprofit Linux advocacy organization.
As I may have mentioned during the SCALE 14x coverage, one of the disadvantages of the glorious burden of working for a great event such as SCALE is that I don’t get out of the media room enough. The fact is, I can’t — herding the cats known as the tech media and processing various social media posts around the event keeps me in the room.
No, we would not say it was easy getting here, but booting into 16.1 for the first time sure is as relieving (and exciting) as it could get for our project growing beyond what we had ever imagined. It has been more than a year since OPNsense first came out. Back then it was FreeBSD 10.0. Not even two months after, 10.1 was introduced along with the opnsense-update utility. Today is the day for FreeBSD 10.2, the latest and greatest release currently available for broader driver support and stability improvements.
The Qt5 (meta-)port and all its dependent ports have been updated to Qt 5.5.1 in FreeBSD. Special thanks to Yuri Victorovich, who did an independent Qt 5.5.1 port and whose work has been gratefully incorporated into this update. Thanks also to Ralf Nolden for pushing for better upgrade-paths and co-installability.
For whatever reason it didn't come for many months until after Skylake CPUs shipped, but LLVM Git/SVN now has Skylake and its features added to the x86 target list.
Elena Demikhovsky of Intel landed this weekend the Skylake x86 target in LLVM that exposes all of the various CPU instruction set extensions supported by these latest-generation processors. There is also the Skylake server processor class for those with AVX-512 support.
The DragonFlyBSD Intel DRM graphics driver sure is getting close to catching up against the upstream Intel Linux graphics driver with the mainline kernel.
The Imaginary Linux Interview from Hell Part 1 [Ed: garbled mess]
The Lumina Desktop Environment is a new, BSD-licensed, graphical system environment which is designed primarily for BSD and UNIX-based operating systems. This focus on BSD systems results in a number of distinct differences in from the current collection of Linux-focused desktop environments, only one of which is independence from all the Linux-based system management frameworks.
Earlier this week I posted the results of a 10-way Linux distribution battle on the same Intel Xeon system and using all of the popular and latest Linux distribution releases. Taking things further, the article today has those results complemented by results on the Xeon system for several BSD operating systems. For seeing how the BSD performance stacks up to Linux, DragonFlyBSD, OpenBSD, and the FreeBSD-based PC-BSD were benchmarked.
If you’re in the packet delivery business, and you’ve never tired OpenBSD, then you’re really missing out. Pretty much everything you care about as a network guy on production networks is configured via a virtual interface. This includes CARP, IPSEC, and all manner of encapsulation and tunneling protocols. This is awesome because all the tools designed to work on interfaces, like tcpdump, work on these virtual interfaces too. So if I want to get a look at my VPN traffic, I can tcpdump enc0.
Which brings up another great point, with OpenBSD, your packet inspection and general network troubleshooting toolbox is way better. Nmap, Argus, sflow, tcpdump, snort, daemonlogger, and etc.. all the best tools are right there on your router if you want them. No need to use a packet tap, because your router is the packet tap.
OpenBSD has myriad built-in daemons for OSPF, BGP, and every other router protocol, as well as application-layer protocol proxies. OpenBSD is by far the fastest, easiest way to setup an ftp proxy that I know of. It also has a kernel-space packet filter called PF, which is crazy feature-rich and and easy to use. If you can console configure an ASA, or are an iptables user, you’ll pick up PF’s syntax in about 15 minutes. All the normal stuff like NAT, redirection, and forwarding are there. Further, PF can do things like policy routing, where you tag packets based on criteria you choose, and then make routing decisions later based on those tags. PF has packet queuing and prioritization built-in, so you can make some classes of traffic more important than others.
First things first: Were I to give an award for Best Presentation Title for SCALE 14X, it would clearly go to iX Systems’ Community Manager (and all-around BSD documentation queen) Dru Lavigne for “Doc Like an Egyptian” — she wins hands down, without question. Dru speaks at SCALE on Saturday, Jan. 23, at 3 p.m.

Months after Axel Davy originally posted his patch-set for the SI machine scheduler to enhance the performance of AMD GCN GPUs on the open-source driver, it looks like the code will soon land in the AMDGPU LLVM back-end.
Axel posted his work on this Southern Islands machine scheduler months ago for AMD's LLVM GPU back-end. As tests showed back in August, this scheduler helps significantly boost the performance for certain workloads. One of the Phoronix readers that tested out this scheduler at the time exclaimed, "The si scheduler is such a huge performance boost! Not only it is faster, but now radeonsi is faster than Catalyst in *all* tests, sometimes by a wide margin!"
LLVM Clang 3.8 has been branched from trunk, thus making LLVM Clang 3.9 the new version under development.
LLVM developers were right on time for branching LLVM 3.8.0 and they are now preparing for the LLVM 3.8 release candidate. A LLVM 3.8 RC2 release is planned meanwhile for 27 January while the official release of LLVM 3.8.0 is expected around mid-February.
