  • Readers Say ‘No’ to Antivirus on Linux
    A few weeks back when Ken Starks wrote an anecdotal column on an experience with a false positive from Avast antivirus on GNU/Linux, we started thinking. We run antivirus on our LAMP servers with the intent of protecting poor suckers on Windows, but on our Linux desktops and laptops? Pretty much, no. Some of us had tried the open source ClamAV at one time or another, mainly out of curiosity, but none of us had stuck with it. To our knowledge, until Starks wrote his column none of us even knew anybody who had ever run proprietary AV on Linux boxes.
  • openSUSE Tumbleweed – Review of the week 2016/4 & 5
  • Almost weekend again – what’s in store
    I updated my packages for calibre and chromium with new versions. I updated the set of “compat32” packages for a multilib setup on slackware64-current to match the Slackware packages contained in the new Slackware 14.2 Beta 2.
  • Slackware 14.2 Beta 2 Announced
    Good news for everyone. Slackware 14.2 is getting close to release as Pat now announced Slackware 14.2 Beta 2 on the latest changelog. This update also brings some security changes for all supported Slackware releases back to Slackware 13.0!!!
  • Make a $40 Linux or Android PC with this tiny new Raspberry Pi 2 rival
    If you want to build a powerful $40 Linux or Android PC with 4K video support, consider Hardkernel’s Odroid-C2 computer. The developer board is an uncased computer like the popular Raspberry Pi 2, which sells for $35. But South Korea-based Hardkernel claims Odroid-C2 has more horsepower than its popular rival and can be a desktop replacement.

Kernel Space: Linux, Graphics

  • Unikernels
    When Linux applications have bugs that are difficult to diagnose (EG buffer overruns that happen in production and can’t be reproduced in a test environment) there are a variety of ways of debugging them. Tools such as Valgrind can analyse memory access and tell the developers which code had a bug and what the bug does. It’s theoretically possible to link something like Valgrind into a Unikernel, but the lack of multiple processes would make it difficult to manage.
  • Robert Hallock: GPUOpen is AMD’s Long-Term Open Source Strategy
    Last week AMD completed a major step in its initiative to open things up to the public under GPUOpen — a collection of tools for graphics, high performance compute and heterogeneous computing – as open source under the MIT license model. So when a company does something out of the ordinary, especially one with a large indirect influence in the mobile community, it’s worth looking further into it. I recently had the opportunity to speak with Robert Hallock, AMD’s Head of Global Technical Marketing, and ask a few questions about what this all means.
  • A Ton Of Direct3D 9 "Nine" State Tracker Improvements Hit Mesa
  • xf86-video-geode 2.11.18
    Yesterday, I pushed out version 2.11.18 of the Geode X.Org driver. This is the driver used by the OLPC XO-1 and by a plethora of low-power desktops, micro notebooks and thin clients. This release mostly includes maintenance fixes of all sorts. Of noticeable interest is a fix for the long-standing issue that switching between X and a VT would result in a blank screen (this should probably be cherry-picked for distributions running earlier releases of this driver). Many thanks to Connor Behan for the fix!
