Mixing software development roles produces great results

Friday 17th of August 2018 07:01:00 AM

Most open source communities don’t have a lot of formal roles. There are certainly people who help with sysadmin tasks, testing, writing documentation, and translating or developing code. But people in open source communities typically move among different roles, often fulfilling several at once.

In contrast, team members at most traditional companies have defined roles, working on documentation, support, QA, and in other areas.

What is your favorite Linux window manager?

Thursday 16th of August 2018 07:00:00 AM

While many Linux users have a strong preference for a window manager of choice, for those just making their way over from Windows or Mac, it may be hard to understand what a window manager is, or that it's even something you have a choice in. A window manager is the part of your system that dictates how individual application windows look, and how you can interact with, control, and arrange them.

How to navigate your GNOME Linux desktop with only a keyboard

Wednesday 15th of August 2018 07:00:00 AM

Almost ever since I first started using Linux, I've been on a mission to find the perfect window manager.

My first experience with Linux was in the late 90s, and I first tried installing it on my own in the early 2000s. Like many converts, my previous experience was largely with Windows, and so my early mission was to find an experience that closely replicated Windows, or at least let me interact with it in a familiar way.

Automating backups on a Raspberry Pi NAS

Tuesday 14th of August 2018 07:03:00 AM

In the first part of this three-part series using a Raspberry Pi for network-attached storage (NAS), we covered the fundamentals of the NAS setup, attached two 1TB hard drives (one for data and one for backups), and mounted the data drive on a remote device via the network filesystem (NFS). In part two, we will look at automating backups. Automated backups allow you to continually secure your data and recover from a hardware defect or accidental file removal.

HTTP request routing and validation with gorilla/mux

Tuesday 14th of August 2018 07:02:00 AM

The Go networking library includes the http.ServeMux structure type, which supports HTTP request multiplexing (routing): A web server routes an HTTP request for a hosted resource, with a URI such as /sales4today, to a code handler; the handler performs the appropriate logic before sending an HTTP response, typically an HTML page. Here’s a sketch of the architecture:

5 open source strategy and simulation games for Linux

Tuesday 14th of August 2018 07:01:00 AM

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but those games are often not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist.

  • Snapcraft at Europython 2018
    In July, several members of our advocacy and design teams went to Europython 2018 in Edinburgh. It was a really well-organised event, mixing great speakers from a vibrant community at a great location. The main reason for us to get closer to the Python developer community was to promote Snapcraft as the best way to publish on Linux, for app developers in general, and for Python developers in particular. As well as increasing awareness of Snapcraft, we gained a deeper understanding of the needs of Python developers and made contact with interesting products and engineers.

Graphics: Wayland/Weston, Mesa and AMD

  • Wayland 1.16 / Weston 5.0 RC2 Released To Fix Vulnerabilities
    Two release candidates of Wayland 1.16 / Weston 5.0 were not originally scheduled, but it's been necessitated due to some pressing issues both with Wayland and its reference compositor. Samsung's Derek Foreman issued these "RC2" releases on Friday rather than going straight to the official Wayland 1.16 and Weston 5.0 releases. On the Wayland front, Michael Srb found and fixed issues that could cause pointer overflows within Wayland's connection code. These overflow fixes are the only changes in this Wayland 1.15.94 (RC2) version.
  • RAGE & Doom Get Radeon Workarounds In Mesa 18.3-dev
    If you are looking to enjoy id Software's RAGE or Doom VFR games this weekend on Linux via Wine, they should be playing nicer with the latest open-source Mesa graphics driver code. Timothy Arceri at Valve has added a workaround to get RAGE working under Wine with RadeonSI. The workaround is a DRIRC configuration addition for allowing GLSL built-in variable redeclarations. This is enough to get RAGE working with RadeonSI on Mesa Git. Though only RadeonSI is working out currently since the game relies upon the OpenGL compatibility profile mode that is only supported currently by RadeonSI when it comes to the Mesa drivers. Thanks to Valve's developers and others, the OpenGL compatibility profile mode for RadeonSI has matured into great shape these past few months.
  • Adreno 600 Series Support Lands In Mesa 18.3 Gallium3D
    With the Adreno 600 series support going into Linux 4.19 for the kernel bits, the user-space OpenGL driver support for the latest-generation Qualcomm graphics has now been merged into Mesa. Kristian Høgsberg Kristensen of Google's Chrome OS graphics team (yes, Kristian of Wayland and DRI2 fame) has been working on the Gallium3D support for the Adreno 600 series hardware along with Freedreno founder Rob Clark. This A6xx support is being tacked onto the existing Freedreno Gallium3D driver and amounts to just over six thousand lines of new code. Keep in mind this A6xx Freedreno back-end must also be used with the supported MSM DRM driver in the Linux 4.19+ kernel.
  • AMDGPU-PRO 18.30 Radeon Linux Driver Released with Support for Ubuntu 18.04 LTS
    Featuring official support for the AMD Radeon PRO WX 8200 graphics cards and initial Wattman-like functionality, the Radeon Software for Linux 18.30 finally adds support for some of the most recent Ubuntu, Red Hat Enterprise Linux, and CentOS Linux distributions. These include Ubuntu 18.04.1 LTS (Bionic Beaver), Ubuntu 16.04.5 LTS (Xenial Xerus), Red Hat Enterprise Linux 7.5, Red Hat Enterprise Linux 6.10, CentOS 7.5, and CentOS 6.10. SUSE Linux Enterprise Desktop and Server (SLED/SLES) 12 Service Pack (SP) 3 is supported as well, but not the latest SUSE Linux Enterprise 15.

Kernel: Linux 4.19 Staging and Greg Kroah-Hartman's Very Many Stable Releases

  • Linux 4.19 Staging Brings EROFS File-System & Gasket Driver Framework
    Following the USB subsystem updates, Greg Kroah-Hartman sent in the kernel's staging area work for the Linux 4.19 merge window. This experimental/testing area of the Linux kernel is adding a new file-system with 4.19: EROFS. EROFS is developed by Huawei for possible Android device use-cases. EROFS stands for the Extendable Read-Only File-System and is developed to address shortcomings in other Linux read-only file-systems. EROFS features compression support and other features, but the on-disk layout format isn't 100% firm yet -- hence going into the staging area.
  • USB Patches Posted For Linux 4.19 Kernel, Including The New USB-C DisplayPort Driver
    Having wrapped up his latest stable kernel wrangling and the fallout from L1TF/Foreshadow, Greg Kroah-Hartman got around today to sending out the feature pull requests for the kernel subsystems he oversees. His first new batch of changes for Linux 4.19 today is the USB subsystem work.
  • One Week Past Linux 4.18.0, The Linux 4.18.3 Kernel Is Already Out
    Greg Kroah-Hartman had a fun Friday night issuing new point releases to the Linux 3.18 / 4.4 / 4.9 / 4.14 / 4.17 / 4.18 kernels only to have to issue new point releases minutes later. It was just on Thursday that Linux 4.18.1 was released along with updates to older stable branches for bringing L1TF / Foreshadow mitigation. Friday night then brought Linux 4.18.2, Linux 4.17.16, Linux 4.14.64, Linux 4.9.121, Linux 4.4.149, and Linux 3.18.119 with more patches. Those kernels brought various fixes, including in the x86 PTI code for clearing the global bit more aggressively, crypto fixes, and other maintenance work.
