openSUSE Tumbleweed Users Receive Important Mesa Linux Graphics Stack Update

Four snapshots were released this week for OpenSuSE Tumbleweed, which is a rolling release GNU/Linux distribution where users install once and receive updates forever. Probably the most important change added in these snapshots was related to the graphics stack, which was updated to Mesa 17.3.2, a release that neede to be split into two parts to improve the build performance of the distribution. "In order to improve the distro build performance, Mesa was split into two parts to be built. Users that updated their system using “–no-recommends” did not get Mesa-dri auto-installed, resulting in the graphical system possibly not starting up. Simply install Mesa-dri for now manually (dependency chain fixes are underway)," said Dominique Leuenberger in the mailing list announcement. Read more

Raspberry Pi HAT connects up to three Pmod modules at once

Digilent and RS Components have launched a $15, Python supported “Pmod HAT Adapter” for the Raspberry Pi that can connect up to three Digilent Pmod peripheral modules at a time while also extending the 40-pin adapter. Digilent has joined with distributor RS Components to co-launch a $15 DesignSpark Raspberry Pi Pmod HAT Adapter board that brings Digilent’s Pmod peripheral boards to the Raspberry Pi. The 65 x 56.5mm HAT compliant board offers three 2×6-pin Pmod ports with support for I2C, SPI, UART and GPIO interfaces. The Raspberry Pi’s 40-pin adapter is extended to make full use of the SBC’s interfaces. Read more

KaOS 2018.01 KDE-focused Linux distro now available with Spectre and Meltdown fixes

It can be difficult to find a quality Linux distribution that meets your needs. This is partly because there are just too many operating systems from which to choose. My suggestion is to first find a desktop environment that you prefer, and then narrow down your distro search to one that focuses on that DE. For instance, if you like KDE, both Kubuntu and Netrunner are solid choices. With all of that said, there is another KDE-focused Linux distro that I highly recommend. Called "KaOS," it is rolling release, meaning you can alway be confident that your computer is running modern packages. Today, KaOS gets its first updated ISO for 2018, and you should definitely use it to upgrade your install media. Why? Because version 2018.01 has fixes for Spectre and Meltdown thanks to Linux kernel 4.14.14 with both AMD and Intel ucode. Read more
