Graphics DRM and Mesa 18.0.5 RC

  • A Reusable DRM Module To Be Worked On For "Underserved" Graphics Hardware

    While Kevin Brace of the OpenChrome project as the lead and only developer left working on this open-source VIA driver stack has restarted the discussion towards mainlining the OpenChrome DRM/KMS driver, he has decided to take a break from that for a few weeks and to focus on developing a "reusable DRM module" to help other vintage/obscure graphics hardware.

  • Mesa 18.0.5 release candidate

    The candidate for the Mesa 18.0.5 is now available. Currently we have:
    - 21 queued
    - 0 nominated (outstanding)
    - and 5 rejected patches

  • Mesa 18.0.5 Is The Last Planned Release In The Series

    Mesa 18.0.5 is the last planned point release for the Mesa 18.0 series that debuted at the end of March as the Q1'2018 release for Mesa3D.

    With Mesa 18.1 having been released earlier this month and on schedule, the Mesa 18.0 lifespan is relatively short with Mesa 18.1.1 now due for release in the days ahead. As such, the Mesa 18.0.5 release due out by the end of the week is their last planned maintenance release for this previous quarter's branch.

Software: HandBrake, Plex Media Player, zchunk, Qalculate! and Cherrytree

Filed under
Software
  • HandBrake FFmpeg, no more Nvidia 32 bit drivers

    HandBrake has been updated again to track the master branch, as it now uses FFMpeg 4 and no longer libAV 12. This could probably lead to other improvements, like NVENC/CUDA support, more formats, etc.

    Starting with the Nvidia drivers version 396.24 there will be no more 32 bit support, the driver will be 64 bit only. The 32 bit libraries are still included, so Steam and other applications will keep on being supported.

  • Plex Media Player is back!

    Just a small post to notify that Plex Media Player package is back. Now it does not require Conan or Python anymore for building, and you can just build it using standard tools, the dependency issues between the Plex binary packages have been resolved.

  • What is zchunk?

    Over the past few months, I’ve been working on zchunk, a compression format that is designed to allow for good compression, but, more importantly, the ability to download only the differences between an old version of the file and a new version.

    The concept is similar to both zsync and casync, but it has some important differences. Let’s first look at how downloading a zchunk file works.

  • Qalculate! – The Best Calculator Application in The Entire Universe

    I have been a GNU-Linux user and a Debian user for more than a decade. As I started using the desktop more and more, it seemed to me that apart from few web-based services most of my needs were being met with desktop applications within Debian itself.

    One of such applications was the need for me to calculate between different measurements of units. While there are and were many web-services which can do the same, I wanted something which could do all this and more on my desktop for both privacy reasons as well as not having to hunt for a web service for doing one thing or the other. My search ended when I found Qalculate!.

  • Cherrytree – A Feature-Rich Wiki-Style Note-Taking App

    I recently wrote on Thetapad and Zim – both are excellent note-taking applications with their specialty geared towards different users. Today, thanks to suggestions from FossMint readers, I introduce to you Cherrytree.

    Cherrytree is a free and open source note-taking application with wiki-style text formatting, syntax highlighting, and advanced customizability settings.

    Its advanced search function allows you to locate files across the file tree irrespective of their location. It supports keyboard shortcuts, importing and exporting notes, syncing with cloud services like Dropbox, rich text formatting, and password protection to keep your notes secure.

Linux Lite 4.0 "Diamond" Launches Officially Based on Ubuntu 18.04 LTS

Filed under
Linux
Ubuntu

Dubbed "Diamond" and powered by the Linux 4.15 kernel series from the Ubuntu 18.04 LTS (Bionic Beaver) operating system, Linux Lite 4.0 series launches officially today as the first release to drop support for 32-bit installations, bringing numerous updated components, new features and major design changes that include new system theme (Adapta) and icon sets (Papirus).

"Faenza icons were dropped as it had not been maintained in some time (albeit there is a fork) and the same for the Arc theme, development seems to have stalled there," said Jerry Bezencon in the release announcement. "Most of our approach to theming in Series 4.x follows the popular Flat design focus. We also now use the Openzone mouse theme."

Desktop Consolidation Gives SparkyLinux a Clearer Focus

Linux
Reviews

You can run SparkyLinux from a thumb drive. You also can supercharge its performance by loading it into your computer's RAM.

However, the OS is not really as useful if you use it only for a portable computing platform. It performs best when installed on the hard drive. SparkyLinux does not use a frugal installation and special antics to provide persistent memory.

SparkyLinux is a very functional Linux OS. It is a solid choice for use as an all-purpose home edition with all the tools, codecs, plugins and drivers preinstalled.

How open source supports CERN's Large Hadron Collider

Filed under
Server
OSS

The 27-kilometre-long Large Hadron Collider (LHC) buried beneath the France-Switzerland border near Geneva is best known for helping to prove the existence of the Higgs' Boson particle - otherwise known as the God particle - crucial to the Standard Model of particle physics.

The LHC, which uses superconducting magnets to steer beams through its long pipes at just below the speed of light, is supported by open source IT systems at CERN to crunch through about 60 petabytes of data a year. These are built with Openstack, a free and open source software platform for building clouds.

The Openstack cloud first went into production at CERN in July 2013, marking the 13,000-physicist-strong laboratory as an early adopter. Today it has scaled to roughly 300,000 cores – and it's this kind of high-powered, scalable, open source cloud computing that got the attention of many private enterprises, now contributing to the code.

  • So this is why Deepin requires so much disk space for installation – LinuxBSDos.com

    Deepin is a desktop Linux distribution with roots in China. It is based on Debian, but ships with its own graphical interface called Deepin Desktop Environment and a set of Deepin-developed tools to go with it. The last version I installed was from 2015, so since I’m gradually coming back to writing for this blog, I decided to test drive the latest edition – Deepin 20.3, which was released on Nov. 25. For me that means installing it in a virtual environment using VirtualBox. For such installations I typically assign the virtual disk 20GB of disk space. And so it was with Deepin 20.3. But that didn’t end well because at some point the installation failed, with the message shown in Figure 2: “You need at least 64 GB of disk space to install Deepin. To get better performance, 128 GB.”

Everyone should benefit from Bash Scripting. Bash is the most common shell interpreter on Linux systems. When you open a Terminal, you are in an interactive shell environment. To verify that your system is using the Bash shell using the command: 'echo "$SHELL"'.

    “Shutdown” refers to the process of stopping and shutting down a computer or server. This involves cutting the power to the main components of the system using a controlled process. Applications are closed, active processes and protocols are saved to the hard drive, device drivers are removed, and user settings are saved in the process. There are several options to do so, including scheduling a shutdown at a specific time, shutting down immediately, broadcasting a unique message, and so on.

Raspberry Pi CM4-based panel PC offers DAQ inputs and M.2 NVMe

Sensoper’s 7-inch “SC-PC” HMI panel PC runs Linux on a Raspberry Pi CM4 and supplies GbE, M.2 for NVMe, RS-485, 3x USB, 8x digital inputs, 7x transistor outputs, and 8x analog inputs with a choice of 0-10V or 4-20mA ranges.
