With the basement conversion into a big Linux server room where there's 50~60 systems running daily at full load while running our many open-source benchmarks, cooling has been a challenge with now experiencing summer temperatures. I've already resorted to retro-fitting in extra powered ventilation ducts to keep pushing fresh air into the server room. That did some help, but also of aid is upgrading the cooling systems on some of the more powerful systems rather than using the stock heatsinks and fans. For helping out the cooling situation, Noctua sent out a while ago the NH-U12DX i4 and NF-F12.
The latest Mesa 10.5 point release, Mesa 10.5.6, is now available.
NVIDIA has been working out plans for their graphics driver to support Mir and Wayland. As part of that, besides their recent EGL support, they've been tackling kernel mode-setting.
An EXT4 file-system corruption problem was uncovered with Linux 4.0 that turned out to be an MD RAID0 issue with the Linux kernel in the latest stable series. This RAID corruption issue has now been fixed in the latest kernel Git code.
Mesa 10.6 is up to a release candidate state and should be officially released in early June. If you're not up to speed on this quarterly update to the open-source user-space graphics drivers, here's an overview of the new features for Mesa 10.6.
Since last year Canonical has been developing the new LXD hypervisor. As implied by the name, LXD is derived from the success of LXC.
Fedora 22 is shaping up quite well across the Fedora Workstation, Server, and Cloud offerings. Out of curiosity, this week I ran some initial comparison tests of Fedora Server 21 vs. Fedora Server 22.
The latest GNU Compiler Collection code now has proper optimization targeting/tuning support for the IBM z13.
While yesterday there was risk of Fedora 22 being delayed beyond next week, this next Fedora Linux release was cleared today for being released next Tuesday.
The first release candidate to OpenWRT 15.05, the "Chaos Calmer", is now available for testing.
As of this month, the mainline code for LLVM and Clang finally have complete OpenMP support (currently against the OMP 3.1 specification).
Zapcc is the latest compiler I heard about this morning... Zapcc is based on LLVM's Clang C/C++ compiler but claims to be much faster than it.
Version 1.1 of the Godot Game Engine has been released. This open-source game engine update brings a new 2D engine and claims to be one of the most advanced 2D engines for cross-platform games.
Some Video Acceleration API updates are coming down the pipe.
Mark Shuttleworth is reportedly considering a move to make Canonical a public company.
RandR 1.5 was firmed up a few days ago for X.Org Server 1.18. The lead features to RandR 1.5 are monitor objects and tile support.
At today's Go/No-Go meeting it was decided that Fedora 22 Final is not ready for release. However, tomorrow that decision will be re-evaluated.
It's taken a while, but systemd 220 has been finally released.
Following yesterday's LibreOffice 5.0 branching in Git, the first beta for LibreOffice 5.0 is now available for testing.
While there's been work on supporting Apple Pages and Numbers files within LibreOffice, it seems this import support is finally getting squared away for those forced to having to deal with Apple's proprietary document formats.
For months now Allwinner has been violating the GPL and have attempted to cover it up by obfuscating their code and playing around with their licenses while jerking around the open-source community. At least today they've made a positive change in open-sourcing more of their "CedarX" code.
The Linux kernel continues advancing on many hardware fronts, among which is support for ACPI 6.0 and the kernel is making the new LIBND subsystem for non-volatile memory device support.
Fedora 22 is scheduled to be released next week but for that to happen there's still a number of blocker bugs that need to be addressed. The second release candidate of Fedora 22 Final is now available for those wishing to stress this major update of the Red Hat sponsored Linux distribution.
A few days ago we reported on an EXT4 file-system corruption issue being discovered within the stable Linux 4.0 kernel series. The good news is the issue has been uncovered and a patch is available, but it could still be a few days before it starts getting sent out in stable updates.
For those that haven't seen/heard yet, the Ubuntu 15.10 release schedule has now been firmed up.
It's been four years and two weeks since Mark Shuttleworth expressed his goal of "200 million users of Ubuntu in 4 years." While Ubuntu's presence has continued to increase over the past four years, it doesn't look like that goal has been realized yet or will be by the end of the calendar year.
Microsoft has today announced they've open-sourced the important WCF (Windows Communication Foundation) code that now targets .NET Core.
S3TC remains the most common form of texture compression relied upon by video game developers and others, but it remains a legal mess for open-source graphics drivers. ETC2 texture compression isn't faced by legal issues but was only mandated by OpenGL ES 3.0 / OpenGL 4.3, which makes it less well adopted. Meanwhile, in looking forward to the future, ASTC is the royalty-free next-gen texture compression solution that's backed by the Khronos Group. Intel's forthcoming Skylake hardware will make ASTC a much more widespread reality.
Today marks twenty years since the first release of the Qt tool-kit. It's been an interesting twenty years so far going through the hands of Trolltech, Nokia, Digia, and the now spin-off The Qt Company.
Another HTTPS vulnerability has started to make its rounds earlier this morning. Dubbed Logjam by its researchers, the vulnerability stems from the US's encryption export mandate back in the 1990s. This particular vulnerability, in the transport-layer security layer protocol, breaks the Diffie-Hellman perfect forward-secrecy. Susceptibility to the vulnerability is depended on servers and clients supporting the DHE_EXPORT encryption scheme, or using a key less-than-or-equal to 1024 bits.
LibreOffice 5.0 is the next version of this popular, cross-platform, open-source office suite and not LibreOffice 4.5 as was originally planned. LibreOffice 5.0 has now been branched in Git with the trunk development now focusing on LibreOffice 5.1.
Among other OpenGL 4.x extensions, one of the more recent additions to OpenGL being tackled by open-source developers is ARB_shader_storage_buffer_object.
