  • A Quake 2 Game Might Get Ported To Linux

    Berserker@Quake2 has been around since about 2005, but only supported on Windows. Now though the Russian developer behind this game mod has finally published his code in hopes of someone porting it to Linux.

  • KDE Plasma 5.5.3 Comes With 20 Changes
  • KDE's conf.kde.in 2016 Conference to Take Place in Rajasthan, India, on March 5-6

    On January 6, 2016, KDE announced that the upcoming conf.kde.in 2016 conference for KDE developers would take place this spring, between March 5 and 6, in Jaipur, Rajasthan, India.

  • The importance of Keywords for the software center

    So, what do I want you to do? If you have no existing keywords, I would like you to add some keywords in the desktop file or the AppData file. If you want the keywords to be used by GNOME Shell as well (which you probably do), the best place to put any search terms is in the keywords section of the desktop file. This can also be marked as translatable so non-English users can search in their own language. This would look something like Keywords=3D;printer; (remember the trailing semicolon!)

  • The Linux Setup - Ikey Doherty, Solus

    Ikey is living the dream—he made his own desktop environment. Perhaps even more impressive, he made it for his own distribution! Perhaps most impressive of all, Solus, Ikey’s distribution, is built from scratch, meaning it’s not based upon another distribution. It’s a lot of work, but Ikey doesn’t seem to mind it. Ikey also flags git as his essential tool-of-choice. I’m using git to submit chapters for my book and it’s a pretty amazing piece of software. It’s impacting all kinds of work.

  • Hackers rejoice, Kali Linux NetHunter 3.0 Android Mobile Penetration Testing Platform released
  • Debian Project mourns the loss of Ian Murdock

    The Debian Project sadly announces that it has lost the founder of its community and project, Ian Murdock.

    Debian is only a part of Ian's legacy but perhaps the one that he is most known for.

    Ian was introduced to computers early in his life, and his curiosity turned to familiarity which led him to start actively programming at nine years of age. Later as a young adult at the Krannert School of Management a mandatory programming class rekindled his fascination with computer programming along with an idea and an opportunity to make something better.

    Ian started the Debian Project in August of 1993, releasing the first versions of Debian later that same year. At that time, the whole concept of a "distribution" of Linux was new. Inspired as he said by Linus Torvalds' own sharing of Linux, he released Debian with the intention that this distribution should be made openly, in the spirit of Linux and GNU.

  • IBM’s Watson Now Powers AI For Under Armour, Softbank’s Pepper Robot And More

    From its debut to the world as a Jeopardy champion in 2011, IBM’s Watson has made a name for itself as a powerful artificial intelligence platform for large enterprise applications, from medical research through to finance. Now IBM is aiming to take Watson to the consumer.

  • Microservices are not the same thing as components

    Mention cloud, mention DevOps and it won’t be long before microservices enters the discussion.

    But what is, or are, microservices? The name implies something small – but what? Is it a part of a bigger thing or a piece of discrete functionality? And how are microservices different to application components? And why should we care?

Security Leftovers

  • Security updates for Tuesday
  • Initial Retpoline Support Added To LLVM For Spectre v2 Mitigation
    The LLVM code has been merged to mainline for the Retpoline x86 mitigation technique for Spectre Variant 2. This will be back-ported to LLVM 6.0 and also LLVM 5.0 with an immediate point release expected to get this patched compiler out in the wild. The compiler-side work -- similar to GCC's Retpoline code -- is to avoid generating code where an indirect branch could have its prediction poisoned by a rogue actor. The Retpoline support uses indirect calls in a non-speculatable way.
  • Teen Hacker Who Social Engineered His Way Into Top-Level US Government Officials' Accounts Pleads Guilty To Ten Charges
    The teenage hacker who tore CIA director John Brennan a new AOL-hole is awaiting sentencing in the UK. Kane Gamble, the apparent founder of hacker collective Crackas With Attitude, was able to access classified documents Brennan has forwarded to his personal email account by posing as a Verizon tech. Social engineering is still the best hacking tool. It's something anyone anywhere can do. If you do it well, a whole host of supposedly-secured information can be had, thanks to multiple entities relying on the same personal identifiers to "verify" the social engineer they're talking to is the person who owns accounts they're granting access to. Despite claiming he was motivated by American injustices perpetrated around the world (Palestine is namechecked in the teen's multiple mini-manifestos), a lot of what Gamble participated in was plain, old fashioned harassment.
  • The Guardian view on cyberwar: an urgent problem [Ed: Lists several attacks by Microsoft Windows (but names neither)]
    The first known, and perhaps the most successful of these, was the joint US/Israeli Stuxnet attack on the Iranian nuclear programme in 2009. Since then there has been increasing evidence of attacks of this sort by Russia – against Estonia in 2009, and then against Ukraine, where tens of thousands of attacks on everything from power supplies to voting machines have opened an under-reported front in an under-reported war. Across the Baltic, the Swedish government has just announced a beefed-up programme of civil defence, of which the most substantial part will be an attempt to protect its software and networks from attacks. Meanwhile, North Korean state hackers are blamed by western intelligence services for the WannaCry ransomware attacks which last year shut down several NHS hospitals in the UK. Persistent reports suggest the US has interfered in this way with North Korea’s nuclear missile programme.
  • Reproducible Builds: Weekly report #143
  • Don’t Install Meltdown And Spectre Patches, Intel Warns It Would Increase System Reebots
  • On that Spectre mitigations discussion
    By now, almost everybody has probably seen the press coverage of Linus Torvalds's remarks about one of the patches addressing Spectre variant 2. Less noted, but much more informative, is David Woodhouse's response on why those patches are the way they are.

Tails 3.5 Anonymous OS Released to Mitigate Spectre Vulnerability for AMD CPUs

Tails, the open-source Linux-based operating system designed to protect user's privacy while surfing the Internet, also known as Anonymous OS, was updated today to version 3.5. Coming only two weeks after the Tails 3.4 release, which included patches for the Meltdown and Spectre security vulnerabilities publicly disclosed earlier this month, today's Tails 3.5 update is here to bump the Linux kernel to version 4.14.13 and include the microcode firmware for AMD CPUs to mitigate the Spectre flaw.

Graphics: Freedreno, Gallium3D, AMDGPU, RadeonSI, Mesa

  • Code Aurora Working On Adreno 6xx Support For Freedreno
    The Qualcomm-aligned Code Aurora is working on supporting the latest-generation Adreno A6xx graphics hardware with the open-source Freedreno+MSM driver stack.
  • Work Revised On Adding SPIR-V Support To Clover Gallium3D
    Last May we reported on a Nouveau developer adding SPIR-V support to Gallium3D's OpenCL state tracker. Finally the better part of one year later, Pierre Moreau is ready with the second version of these patches to accept this IR associated with Vulkan / OpenCL 2.1+ within Clover.
  • Trying Out DRM-Next For Linux 4.16 With AMDGPU On Polaris & Vega
    I have spent some time this weekend trying out the DRM-Next code slated for inclusion in Linux 4.16 when its merge window opens next week. The DRM-Next state of the AMDGPU driver appears to be in good shape, at least for the RX 580 and RX Vega cards used for my initial testing.
  • RadeonSI NIR Back-End Picks Up Support For More OpenGL Extensions
    It was just a few days ago that Valve Linux developer Timothy Arceri enabled GLSL 4.50 support for RadeonSI's NIR back-end after previously taking care of tessellation shaders and other requirements. Now he has taken to implementing some other extensions in RadeonSI's NIR code-path.
  • mesa 18.0-0-rc1
    The first release candidate for Mesa 18.0.0 is now available. The plan is to have one release candidate every Friday, until the anticipated final release on 9th February 2018. The expectation is that the 17.3 branch will remain alive with bi-weekly releases until the 18.0.1 release. NOTE: Building the SWR with LLVM 3.9 is currently not possible. Please use newer LLVM version until the issue is resolved. Here are the people which helped shape the current release.
  • Mesa 18.0 Now Under Feature Freeze With 18.0-RC1 Premiere
    Feature development on Mesa 18.0 has now ended with the release today of 18.0-RC1 following the code-base being branched. Emil Velikov of Collabora just announced the availability of Mesa 18.0-RC1. As usual, he's planning on weekly release candidates until the 18.0.0 stable release is ready to ship. Velikov tentatively expects to ship Mesa 18.0.0 around 9 February, but as we know from past releases, it might end up slipping by some days.

Using Dual 4K Monitors Stacked With GNOME

The setup for my main production system that is still on Fedora Workstation 26 with GNOME Shell 3.24.3 has been working out fine. The two displays are the ASUS MG28UQ monitors that work out well on their own and do work with AMDGPU FreeSync on Linux. A GeForce GTX 1050 Ti is enough to power the dual 3840 x 2160 displays for desktop tasks mostly limited to many terminals, Firefox, Chrome, Thunderbird, and other GNOME desktop applications. Certainly that lower-end Pascal GPU isn't fast enough for 4K gaming, but it's not like I have the time for any gaming and for a purely desktop system it's working out fine paired with the 387.34 proprietary driver on Fedora 26 paired with Linux 4.14.
