Multipass, the Canonical-led open-source project that aims to make it easy to spin up Ubuntu VM instances on Linux and Windows and macOS, is up to version 0.9 ahead of a possible 1.0 release for Ubuntu 20.04 LTS...

Last month we reviewed the OnLogic Karbon 700 as a passively-cooled, industrial-grade PC powered by an eight-core / sixteen-thread Intel Xeon, 16GB of RAM, 512GB NVMe storage, and a plethora of connectivity options in suiting to industrial use-cases. The performance was great and even the thermal performance was very good for being a fan-less PC. In seeing how well other Linux distributions were panning out on the Karbon 700, I tested five popular Linux distributions on the Xeon Coffee Lake system and once again Intel's performance-optimized Clear Linux squeezed out much more performance potential.

Intel Labs announced "Horse Ridge" as a cryogenic control chip to enable more development and testing around full-stack quantum computing systems...

The WireGuard secure VPN tunnel kernel code has landed in net-next! This means that -- barring any major issues coming to light that would lead to a revert -- WireGuard will finally reach the mainline kernel with the Linux 5.6 cycle kicking off in late January or early February!..

One of the most frequent complaints we hear from Linux gamers running open-source GPU drivers is over the lack of the hardware vendors supporting any feature-rich control panels like they do on Windows. There are many Linux driver tunables exposed by these open-source graphics drivers, but often they can only be manipulated via command-line options, environment variables, boot parameters, and other less than straight-forward means especially for recent converts from Windows and other novice Linux users. ADriConf has been doing a fairly decent job as a third-party means of helping to improve the situation and now there is talk of it supporting Vulkan driver settings...

Back in September we wrote about Facebook's Roman Gushchin working on a new slab memory controller/allocator implementation that in turn could provide better memory utilization and less slab memory usage. This wasn't ready in time for the 5.5 kernel but a revised patch series was sent out last week...

This weekend was the last-minute pull request by Google's Kees Cook to introduce the new sizeof_member() macro that had been previously rejected from Linux 5.4. Well, it was again rejected by Linus Torvalds prior to tagging the Linux 5.5-rc1 kernel...

While there are some pretty great features for Linux 5.5, one that didn't make it quite in time was the long-awaited introduction of WireGuard as the in-kernel secure VPN tunnel. While it was a bummer it didn't make 5.5, all indications are at this point is that it will be in Linux 5.6...

Linus Torvalds has just issued the first release candidate of the Linux 5.5 cycle following the traditional two week long merge window...

Announced back in September at the All Systems Go event in Berlin was systemd-homed as a new effort to improve home directory handling. Systemd-homed wants to make it easier to migrate home directories, ensure all user data is self-contained, unify user-password and encryption handling, and provide other modern takes on home/user directory functionality. That code is expected to soon land in systemd...

With AMD last week having enabled OpenGL 4.6 for their RadeonSI OpenGL Linux driver when enabling the NIR intermediate representation support, you may be wondering how using NIR is stacking up these days compared to the default TGSI route. Here are some benchmarks on Polaris, Vega, and Navi for comparing this driver option that ultimately allows OpenGL 4.6 to be flipped on.

Red Hat has been working on a "general notification queue" that is built off the Linux kernel's pipe code and will notify the user-space of events like key/keyring changes, block layer events like disk errors, USB attach/remove events, and other notifications without user-space having to continually poll kernel interfaces. This general notification queue was proposed for Linux 5.5 but has been pushed back to at least 5.6...

Since the AMD EPYC 7002 "Rome" series launch in August we have continue to be captivated by the raw performance of AMD's Zen 2 server processors across many different workloads as covered now in countless articles. The performance-per-dollar / TCO is also extremely competitive against Intel's Xeon Scalable line-up, but how is the power efficiency of these 7nm EPYC processors? We waited to deliver those numbers until having a retail Rome board for carrying out those tests and now after that and then several weeks of benchmarking, here is an extensive exploration of the AMD EPYC 7002 series power efficiency as well as a look at the peak clock frequencies being achieved in various workloads to also provide some performance-per-clock metrics compared to Naples.

With each new release of Firefox we set out to see how the performance is looking on the Linux desktop. One discovery we've made is that when using Intel's Clear Linux the Firefox performance is a lot more competitive to Google Chrome than we traditionally see on Ubuntu Linux. But with Firefox 71 we're seeing the performance trending lower compared to Firefox 69 and 70...
