Continuing on from the recent technical vision for the Qt6 tool-kit, The Qt Company has now announced their new high-level 3D API they are developing for this next major release of Qt...

GCC 4.2.1 has been out since 2007 and while there have been many big updates to the GNU Compiler Collection over the past decade, that version remains somewhat common in the BSD land due to being the last version under the GPLv2 license. GCC 4.2.2 and newer switched over to GPLv3+ and that is why several BSDs have stuck to using GCC 4.2.1 or at least keeping it in their base repository. But now for FreeBSD 13, this old version of GCC is set to be retired with FreeBSD already being quite focused on LLVM Clang as its default compiler while also offering newer GCC versions via its package management system...

It's now been one week since the launch of AMD's EPYC Rome processors with up to 64 cores / 128 threads per socket and better IPC uplift compared to their previous-generation parts. Rome has outperformed Intel Xeon Scalable CPUs in their class while offering better power efficiency and way better performance-per-dollar. One of my favorite metrics has been how quickly the new EPYC 7742 2P can build the Linux kernel...

With TrueOS (formerly PC-BSD) no longer focused on delivering a quality BSD desktop as they once did, while there still are options out there for a desktop-focused BSD like MidnightBSD, for those wanting to use a vanilla FreeBSD installation can now setup a desktop easier using a new script...

Up until today the newest Linux kernel version supported by the official Reiser4 out-of-tree file-system driver patch was Linux 5.0, but that has now changed with the belated Linux 5.1 kernel support arriving as well as a separate patch for Linux 5.2 kernel support...

With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device.

Last week was the Intel Gallium driver one line patch to boost performance by 1%. Today's code churn within Mesa for Intel's open-source Linux graphics drivers were larger but also with a more profound performance impact with some workloads now being faster by around 20%. Making this more exciting is that today's round of driver optimizations apply to the very common and mature "Gen 9" graphics hardware...

Gentoo's AArch64/ARM64 support for 64-bit ARM should now be in good shape...

With last week's dramatic EPYC "Rome" launch where AMD has blown past Intel Xeon "Cascadelake" performance in a majority of server benchmarks, helping the successful launch of these Zen 2 server processors has been Intel's repeated delays of 10nm/Icelake CPUs and also the Spectre / Meltdown / Zombieload / Foreshadow mitigations. Out of curiosity, I've run some unmitigated benchmarks for the various relevant CPU speculative execution vulnerabilities on both the Intel Xeon Platinum 8280 Cascadelake and AMD EPYC 7742 Rome processors for seeing how the performance differs.
