5 Reasons Why This Linux Gaming OS Is Great For Your Living Room

Filed under
Linux
Gaming

Valve’s Steam Machines initiative has been retired and SteamOS is on hiatus, but Steam Big Picture mode is still an awesome way to transform your PC into a living room console experience. For those of us who like the idea of having a computer dedicated to couch gaming (read: not your daily driver OS), a boutique Linux distribution called GamerOS is worth checking out. Especially since it picks up the baton where Valve left off and adds substantial tweaks and improvements.

In a nutshell, GamerOS is an Arch Linux-based operating system that’s streamlined to do one thing very well: run Steam Big Picture. In fact, that’s all it does. There is no desktop environment. Your first boot places you directly into Steam Big Picture and that’s where you’ll live on GamerOS.

KDE Plasma 5.18.4 LTS Desktop Environment Brings More Than 40 Fixes

Filed under
KDE
Security

Coming three weeks after the Plasma 5.18.3 point release, which introduced a bunch of Flatpak improvements and more than 60 fixes, the KDE Plasma 5.18.4 LTS release is here to add more than 40 bug fixes to various of the desktop environments core components.

Among the changes, there’s improved support for the upcoming Qt 5.15 application framework for Breeze and libksysguard components and better support for the fwupd open-source daemon for installing firmware updates on devices in the Discover package manager.

Flatpak support in Discover was also improved by fixing two issues. Moreover, XSettingsd was added as a runtime dependency to KDE GTK Config, kwallet-pam now works with pam_fscrypt, and KWin now allow the creation of more than one row on the “Virtual Desktops” settings page.

Obarun – An Arch Based Linux Distro Without Systemd

Filed under
Linux

Today’s Linux distribution review is not just for distro hoppers who love to try something new but it’s for people who have a specific purpose such as a Linux system without systemd. Systemd, as we all know, has always been criticized by a lot of developers and Linux users.

Obarun is packed with enough utilities to install & start a vanilla Arch Linux without any trouble. I have written an article on how to install Arch step by step and it is a long article. But Obarun does the Arch installation in a very simple way. It comes with obarun-installer, a script that helps install Arch as easily as possible.

40 Practical and Useful awk Command in Linux and BSD

Filed under
Linux

AWK is a powerful data-driven programming language that dates its origin back to the early days of Unix. It was initially developed for writing ‘one-liner’ programs but has since evolved into a full-fledged programming language. AWK gets its name from the initials of its authors – Aho, Weinberger, and Kernighan. The awk command in Linux and other Unix systems invokes the interpreter that runs AWK scripts. Several implementations of awk exist in recent systems such as gawk (GNU awk), mawk (Minimal awk), and nawk (New awk), among others. Check out the below examples if you want to master awk.

Behind Plasma Bigscreen

Filed under
KDE

Plasma has been designed from the get go (2006 or so.. it seems at least 2 eternities agoto not make any assumptions on the type of device and to do a clear separation between the core technology/runtime and the various GUI plugins that end up implementing a full desktop experience.

In an architecture decision informed by previous prototypes we did in KDE4 times for mobile devices UIs, in Plasma 5 we split it further and introduced the concept of a “shell package” which lets further customization between devices than what Plasma in KDE4 times allowed.

Because of that we could do the Plasma Mobile shell without changes to the architecture that runs both the Desktop shell and the mobile version, despite being a completely different UI.

  • qView is a minimalistic image viewer for Windows, Linux and macOS

    The program doesn't use a lot of resources when you use it normally. I did notice a memory spike viewing a slideshow of high resolution photos, it jumped from 75MB to 150MB, but that may have been due to the fact that the picture was very large in size. Otherwise, it stayed in the 70s for the most part.

  • 6 Open-Source AI Frameworks You Should Know About

    Google’s open-source framework TensorFlow is an ecosystem of tools, libraries and resources that’s used by many popular companies like Airbnb, eBay, DropBox and more. TensorFlow aims to simplify and abstract away the complexity of machine learning algorithms to streamline development. Using visual models and flowgraphs, developers and data scientists can quickly create neural networks and other machine learning models to leverage data. Airbnb, for example, is using TensorFlow to categorize apartment listing photos to ensure they accurately represent a particular space.

  • Jonathan Carter: Free Software Activities for 2020-03

    On the 12th of March, I posted my self-nomination for the Debian Project Leader election. This is the second time I’m running for DPL, and you can read my platform here. The campaign period covered the second half of the month, where I answered a bunch of questions on the debian-vote list. The voting period is currently open and ends on 18 April. [...] At DebConf19 I wanted to ramp up the efforts to make a Debian PeerTube instance a reality. I spoke to many people about this and discovered that some Debianites are already making all kinds of Debian videos in many different languages. Some were even distributing them locally on DVD and have never uploaded them. I thought that the Debian PeerTube instance could not only be a good platform for DebConf videos, but it could be a good home for many free software content creators, especially if they create Debian specific content. I spoke to Rhonda about it, who’s generally interested in the Fediverse and wanted to host a instances of Pleroma (microblogging service) and PixelFed (free image hosting service that resembles the Instagram site), but needed a place to host them. We decided to combine efforts, and since a very large amount of fediverse services end with .social in their domain names, we ended up calling this project Debian Social. We’re also hosting some non-fediverse services like a WordPress multisite and a Jitsi instance for video chatting.

  • You Need To Stop Using HTML Email

    We need to change this norm from the ground up as a grass roots effort. We'll never convince Gmail and others to automatically display emails in plain text for all users. Nor will we convince companies to stop sending HTML emails to their clients. The only way is to start sending plain text emails and setting up our email programs to only display our received emails as plain text.

    As more and more people do this the companies will begin to follow suite due the increasing number of people being unable to easily read their messages.

    It's also our duty as good email users to only every send emails as plain text because we can not always be sure that the receiver of our emails is using a program that will render out all the HTML instead of displaying it as a webpage.

    Keep in mind that by plain text I don't mean you should not encrypt your emails. If you need to encrypt them then please do; PGP and GPG work very well. When sending an encrypted message; type up your message, encrypt it, and the paste the encrypted output into the email as plain text.

  • Safer SSH agent forwarding

    As mentioned, a better alternative is to use the jump host feature: the SSH connection to the target host is tunneled through the SSH connection to the jump host. See the manual page and this blog post for more details.

    If you really need to use SSH agent forwarding, you can secure it a bit through a dedicated agent with two main attributes:

    it holds only the private key to connect to the target host, and

    it asks confirmation for each requested signature.

  • LLVM's Flang/F18 Fortran Compiler Might Be Back On Track For Merging Soon

    Since the "f18" open-source Fortran compiler front-end was approved last year for merging as the newest LLVM sub-project and using the Flang name, there have been a number of false starts in getting the code merged. This year alone Flang had multiple delays and cancelled merge plans as the developers worked to get the code ready for upstream. Now though it looks like it could be ready to cross that long sought after milestone for having an in-tree Fortran front-end. Richard Barton announced today that the team now believes F18 is ready to be merged. There still are some open items still being worked on, but should be easily resolved after the F18 code is within the tree as the new "Flang" compiler.

  • A Telegram bot in Haskell on Amazon Lambda

    So instead adding layers and complexities, can I solve this instead my making things simpler? If I compiler my bootstrap into a static Linux binary, it should run on any Linux, including Amazon Linux. [...] I am mostly happy with this setup: My game is now available to more people in more ways. I don’t have to maintain any infrastructure. When nobody is using this bot no resources are wasted, and the costs of the service are neglectible -- this is unlikely to go beyond the free tier, and even if it would, the cost per generated image is roughly USD 0.000021. There is one slight disappointment, though. What I find most intersting about Kaleidogen from a technical point of view is that when you play it in the browser, the images are not generated by my code. Instead, my code creates a WebGL shader program on the fly, and that program generates the image on your graphics card.
