Yep, Pop OS 21.04 Will Have Exactly What You’ve Wanted

Filed under
OS

What’s the first thing you do after installing a fresh copy of Linux distro Pop OS? I’d wager the majority of you install Gnome Tweaks, Dash to Dock, or Dash to Panel. Jeremy Soller, Principal Engineer at System76 (the hardware company also responsible for developing Pop OS), is well aware of this.

“90% of the screenshots on the Pop OS subreddit have a dock,” he says in my upcoming Linux For Everyone interview. “It’s something we want to provide out of the box.”

Following that, Soller drops all kinds of info bombs regarding Pop OS 21.04 (yep, there will be a public beta). Specifically, System76 will be integrating Gnome-Tweaks and building upon it.

We are astonished by your generosity and loyalty

Filed under
OS

EndeavourOS has been around the block for almost two years now, so we are a pretty young distro that still is exploring and discovering new options whilst making its journey. When we started our journey back in the last days of Antergos in 2019, there were a few thoughts of doubt that did linger in the back of my mind.

Will we be able to produce and maintain a distro and how are we going to reach new users? Given the fact that none of us had any experience in creating a distro and also, from the start, we had a fair share of an existing community watching over our shoulders, which didn’t make things easier to push that lingering feeling aside.

postmarketOS Tweaks makes it easy to customize this Linux distro for phones

Filed under
OS
Linux

There’s a free and open source tool called GNOME Tweaks that lets you customize a number of settings for desktop and laptop computers using the GNOME desktop environment.

Now developer Martijn Braam is bringing that idea to mobile devices. The new postmarketOS Tweaks tool is inspired by GNOME Tweaks, but as the name suggests it’s designed for phones and other devices running the postmarketOS Linux distribution.

Ohai there, LineageOS 18.1

Filed under
OS

Man, it’s been a while!

Firstly, hey, how are you doing? 2020 has been notably tough on all of us in different ways. Most of us were either stuck indoors or uncomfortably out and about for most of last year. It affected every industry, company, and project in a different way. Given that LineageOS has developers spanning the globe, our contributors all felt last year to varying extents - but what is a community if not to be there for its members, and give them something to spend all that time stuck inside working on Smile.

With that said, we have been working extremely hard since Android 11’s release last August to port our features to this new version of Android. Thanks to our hard work adapting to Google’s fairly large changes in Android 10, we were able to rebase our changes onto Android 11 much more efficiently. This led to a lot of time to spend on cool new features!

As always, let’s talk about versioning conventions - you may be thinking “Shouldn’t this be 18.0, as AOSP is on 11, and not 11.1?”. As we stated in our last blog post, after 17.0, whenever we conduct a platform wide rebase, we will be incrementing our minor version. So, when we rebased on the December Android Security Bulletin (ASB) due to its fairly massive changes, LineageOS 18.1 was born.

Bored By Android And iOS, Elon Musk To Launch DogeOS

Filed under
OS

Tesla CEO Elon Musk is one of the most creative individuals that we’ve come across in the history of humankind. In 2018, when he was stuck in traffic — the next thing he did was build an underground tunnel and started selling hats. After selling 50,000 hats, he eventually got bored of hats and started selling flamethrowers, and he sold 25,000 of them.

At this point, it’s safe to assume that Elon Musk can do anything, right? Right. The world’s richest man is now aiming to develop an open-source, Linux-based operating system for smartphones, and it’ll be called DogeOS. Yes, you heard that right. DogeOS will compete with the likes of Android and iOS.

Review of KDE-Based JingOS 0.8

Filed under
OS
KDE
Reviews

There's something that worrys me: it seems like much of JingOS code is not currently open source. Some applications are – mostly those that are taking from KDE and re-skinned – but the shell itself isn't. Maybe I just could not find the source code, but I think they did not yet upload it at all.
Update: Current repository is: https://github.com/JingOS-team/JingOS
According to the devs, all code should be here from later today.
There were also some licensing issues with original KDE files. Apparently some of the gestures files credits are not given, plus some other licensing technicality which I did not understand. However, the KDE eV Board is in contact with JingOS, so I'd expect these issues to be ironed out eventually.

Now, this is just a preliminary review, as the product only came out today. I wished to do a more in-depth review, but JingOS provided to be an environment not very friendly to different hardware compared to the one it's tested for: no way to change screen resolution (which is wrong by default)? no way to change the keyboard layout? I've also had issues installing third party applications, such as the screen recorder. The one I managed to install (SimpleScreenRecorder) did not work, as JingOS uses Wayland.

The v1.0 will be released in June, and by then we should also have the first all-jing device (the JingPad). Hopefully, I'll be able to get a clearer idea of what JingOS is or will be by then.

Linux Distro Pop OS Now Supports AMD Radeon RX 6000 GPUs

Linux

More than 4 months ago, AMD’s Radeon RX 6800 series launched, and I wrote an enthusiastic Windows-based review here at Forbes. Team Red had finally, triumphantly entered the high-end GPU market and was competing head-to-head with Nvidia. The in-house reference designs were also beautifully built, so that didn’t hurt my recommendation.

What you won’t find here is my Linux review, because I didn’t do one. However, I did produce a somewhat divisive video that bemoaned the extensive hoops anyone not using Ubuntu LTS had to jump through to get these cards recognized and working on the penguin side of things.

Linux

JingOS is a Linux distribution designed for tablets, with a touch-friendly user interface designed to resemble iPadOS or Android. The operating system is based on Ubuntu Linux and KDE’s Plasma Mobile user interface, but it features a custom home screen, status and quick settings tools, settings utility, file browser, and more.

After an initial release earlier this year, the software is under active development and today the team released JingOS v0.8 which is the first build to support over-the-air updates, include an app store, and other improvements.

  • Robert O'Callahan: Visualizing Control Flow In Pernosco

    In traditional debuggers, developers often single-step through the execution of a function to discover its control flow. One of Pernosco's main themes is avoiding single-stepping by visualizing state over time "all at once". Therefore, presenting control flow through a function "at a glance" is an important Pernosco feature and we've recently made significant improvements in this area. This is a surprisingly hard problem. Pernosco records control flow at the instruction level. Compiler-generated debuginfo maps instructions to source lines, but lacks other potentially useful information such as the static control flow graph. We think developers want to understand control flow in the context of their source code (so approaches taken by, e.g., reverse engineering tools are not optimal for Pernosco). However, mapping potentially complex control flow onto the simple top-to-bottom source code view is inherently lossy or confusing or both. For functions without loops there is a simple, obvious and good solution: highlight the lines executed, and let the user jump in time to that line's execution when clicked on. In the example below, we can see immediately where the function took an early exit.

  • Marco Castelluccio: On code coverage and regressions

    There are two schools of thought when it comes to code coverage: those who think it is a useless metric and those who think the opposite (OK, I’m a bit exaggerating, there are people in the middle…). I belong to the second “school”: I have always thought, intuitively, that patches without tests are more likely to cause postrelease regressions, and so having test coverage decreases risk. A few days ago, I set out to confirm this intuition, and I found this interesting study: Code Coverage and Postrelease Defects: A Large-Scale Study on Open Source Projects. The authors showed (on projects that are very different from Firefox, but still…) that there was no correlation between project coverage and the amount of bugs that are introduced in the project and, more importantly, there was no correlation between file coverage and the amount of bugs that are introduced in the file.

Nvidia GPU Passthrough To Windows VM From Linux Host

Nvidia has now officially enabled GPU passthrough support for Windows virtual machines on GeForce graphics cards. In other words, this effectively means it?s possible to run a Linux machine and then run a virtual Windows machine within it, and hand that unfettered access to a graphics card. This is a big win for those wanting to run Windows games from within a virtual machine on your Linux desktop. They will be able to play Windows-based games using a virtual machine with GPU passthrough enabled. Read more

  • A brief intro to Red Hat OpenShift for Node.js developers – IBM Developer

    Container-based deployment models are the modern way to develop and deliver your applications. The most common tool for building with containers is Kubernetes, an open-source container-orchestration system for automating computer application deployment, scaling, and management. Kubernetes has helped usher in a standardized way to deploy and manage applications at scale, but it can be a sprawling, difficult beast to manage when your application becomes more mature and more complex. A company will need to have a robust DevOps team to manage a full-fledged Kubernetes-based production system. [...] My colleague, JJ Asghar summed it up nicely: “OpenShift provides creature comforts to talk to the Kubernetes “API”—at the same level of robustness—as long as you’re willing to use the opinions OpenShift brings.” The good news? Those opinions are tried and tested, enterprise-ready choices with the backing and support of Red Hat. So, what do Node.js developers need to know about OpenShift deployment? This blog post covers the “what” and “how” of deploying your Node.js application in an OpenShift environment.

  • How Red Hat data scientists use and contribute to Open Data Hub

    Artificial intelligence (AI) and machine learning (ML) drive much of the world around us, from the apps on our phones to electric cars on the highway. Allowing such things to run as accurately as possible takes huge amounts of data to be collected and understood. At the helm of that critical information are data scientists. So, what’s a day on the job look like for data scientists at Red Hat? Don Chesworth, Principal Data Scientist, gives you a glimpse into his day-to-day in a short video (aptly named "A Day in the Life of a Red Hat Data Scientist") that’s now available on our website. Isabel Zimmerman, Data Science Intern, provides a look at some of the tools she uses on the job in "Using Open Data Hub as a Red Hat Data Scientist." We’ll cover some of the highlights in this post.
