First Look: Manjaro ARM Beta 1 with Phosh on the PinePhone
The next version of the PinePhone to ship will be the Manjaro Community Edition version which is currently up for pre-order for $150 and up. But if you already have a PinePhone, you can try out the Manjaro software that will be shipping with that phone.
Manjaro ARM Beta1 with Phosh is now available for download, and while it’s still a little rough around the edges, it’s already one of the most polished operating systems available for the PinePhone.

There’s also a version of the Nemo file manager, calculator and calendar apps, document and image viewers, a text editor, a maps application with support for GPS location and data from OpenStreeMap, and utilities for analyzing system resource and power usage, among other things.
The Software app is also more functional, allowing you to browse and search for applications and install a variety of packages. Some of the Not every app I installed was actually able to run, but I was able to install and run a couple of programs and simple games.
Videos/Shows: AppImages, Ubuntu Budgie 20.10, Vim Tabs, KDE Plasma 5.20
AppImages are self-contained applications which can simply be downloaded, made executable, and t run on almost any GNU/Linux distribution. There ease-of-use has won me over.
I've been using vim as my primary text editor for ages and somhow I had just never bothered to actually try out the tab system build into this editor vim has had tabs forever but I just never bothered to see whether they would suit my workflow.
KDE Plasma has a new release out, Plasma 5.20. We need to talk about this, and spoilers: even if you hated KDE before, you should give it another shot.
Pop!_OS 20.04 Review: The Best Ubuntu-based Distro!
The Linux distro world is getting better each day, thanks to developers’ immense dedication. The OS sure has come a long way from people calling it “Complex to use” to “User/Beginner Friendly.” One of the best beginner-friendly distros recommended by almost everyone is Ubuntu. Another distro that has recently taken the Linux universe by storm with its new release is Pop!_OS 20.04; it is developed by System 76, a company that manufactures Laptops and ships them with Linux.
Pop!_OS is a distro based on Ubuntu that has gained popularity lately. After using it extensively for three weeks, it has now become one of my favorite distros of all time. Here’s my review of the same.
The latest release of Zorin OS has hit the internet. The new release is known as Zorin OS 15.3, and it is packed with the latest features and improvements. In this guide, we’ll show you how to install a fresh copy of Zorin OS 15.3!
Please note that to use Zorin OS 15.3, you must have a computer with a decently fast CPU, at least 20 GB of hard drive storage, and at least 1 GB of RAM.
This video provides an introduction to using the firewalld utility.

In this tutorial, we will show you how to install Nextcloud on Ubuntu 20.04 LTS. For those of you who didn’t know, Nextcloud is an open source self-hosted file sync and share application (Calendar, Contacts, Documents, Email, and more).
Linux systems can be optimized into having longer battery usage, courtesy of Slimbook battery saver. Slimbook battery saver is an open-source tool which was created by the Slimbook hardware manufacturer (Manufactures and sells laptops running on Linux based operating systems). It is effective in GNOME, KDE, Cinnamon, Unity, and MATE desktop environment.
Today we are looking at how to install Atom text editor on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
Sometimes, when you try to install a program or a package from its source code, you might end up getting an error which looks like :
“error while loading shared libraries: cannot open shared object file No such file or directory”
We'll show you how to install the pip package manager for both Python 3 and Python 2 on an Ubuntu 20.04 VPS.
[...]
Both Python 2 or Python 3 can be installed on Ubuntu 20.04. However, with Ubuntu 20.04, the default version is Python 3. If for some reason you need Python 2 along with its version of pip, don’t worry, we’re covering that in this tutorial as well.
Pip is not installed by default on Ubuntu – however, the installation is quite quick and simple. Let’s start with the installation.
About a lifetime ago (5 years), I wrote a tutorial on how to configure my Yubikey for OpenPGP signing, SSH authentication and SSH 2FA. In there, I used the libpam-oath PAM plugin for authentication, but it turns out that had too many problems: users couldn't edit their own 2FA tokens and I had to patch it to avoid forcing 2FA on all users. The latter was merged in the Debian package, but never upstream, and the former was never fixed at all. So I started looking at alternatives and found the Google Authenticator libpam plugin. A priori, it's designed to work with phones and the Google Authenticator app, but there's no reason why it shouldn't work with hardware tokens like the Yubikey. Both use the standard HOTP protocol so it should "just work".
From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake.
For Tiger Lake (and theoretically Rocket Lake as well), a new and significant optimization landed today in Mesa 20.3-devel. The optimization applies for Intel Gen12 graphics except for discrete/DG1 graphics.
Version 1.2.158 of the Vulkan specification introduces VK_KHR_fragment_shading_rate that lets developers change the rate at which fragments are shaded on a per-region, per-primitive or per-draw basis and VK_KHR_shader_terminate_invocation which, together with the previously introduced VK_EXT_shader_demote_to_helper_invocation extension, lets developers do a much more specific OpKill.
An independent party has slowly begun merging patches into mainline Mesa for allowing the open-source Radeon Vulkan driver "RADV" to build on Microsoft Windows.
AMD is not behind this effort nor Valve but has been worked on in recent months for making Mesa's Radeon Vulkan driver code compatible with Windows. James Park of a little known "Lag Free Games" has been behind this initiative to bringing it to Windows and seemingly only explaining in private to upstream Mesa developers his motivations for doing so.
RADV as a reminder is the Mesa Radeon Vulkan driver started out by David Airlie of Red Hat and Bas Nieuwenhuizen of Google in the time while waiting for AMD to open-source their Vulkan driver. AMD ultimately provided "AMDVLK" as their official open-source Vulkan driver derived from their internal Vulkan driver sources and built against the AMDGPU LLVM compiler back-end.
The fourth release candidate of OpenZFS 2.0 is now available for testing of this open-source ZFS file-system implementation currently for Linux and FreeBSD platforms.
OpenZFS 2.0 is a big update for this project in that it mainlines FreeBSD support, Zstd file-system compression is a new option, various performance improvements, sequential resilvering, fast clone deletion, persistent L2ARC, and a number of other changes compared to the state of the current ZFSOnLinux 0.8 stable series.
The FUSE implementation for supporting file-systems in user-space is seeing important kernel work merged for Linux 5.10.
The most prominent change with FUSE in Linux 5.10 is a "DAX" mode for allowing direct access to the host page cache. Making use of this direct access support for the host page cache is the VirtIO-FS file-system for sharing files/folders with virtualized guests.
By allowing direct access to the host page cache, there is no longer any double caching and most I/O operations should be significantly faster.
The annual KVM forum conference is next week. It brings together the world's leading experts on Linux virtualization technology to present their latest work. The conference is virtual this year, with live attendance from October 28-30, or check out the recordings once they are available! https://events.linuxfoundation.org/kvm-forum.
We have a good number of engineers from the Oracle Linux kernel development team who will be presenting their work at the forum.
Alexandre Chartre presents KVM Address Space Isolation, a kernel enhancement that provides a separate kernel address space for KVM when running virtual machines. This provides an extra level of protection against speculative execution exploits, improving security for all, and also was a hot topic at the Linux Plumbers Conference earlier this year.
The Fintech Open Source Foundation (“FINOS“), together with platinum member Goldman Sachs (GS), today announced the launch of Legend, Goldman’s flagship data management and data governance platform. Developed internally and used by both engineers and non-engineers alike across all divisions of the bank, the source code for five of the platforms’ modules have today been made available as open source within FINOS.
Today’s launch comes on the heels of the completion of a six-month pilot in which other leading investment banks, such as Deutsche Bank, Morgan Stanley and RBC Capital Markets, used a shared version of Legend, hosted on FINOS infrastructure in the public cloud, to prototype interbank collaborative data modeling and standardization, in particular to build extensions to the Common Domain Model (CDM), developed by the International Swaps and Derivatives Association (ISDA). This shared environment is now, starting today, generally available for industry participants to use and build models collaboratively. With the Legend code now available as open source, organizations may also launch and operate their own instances. The components open-sourced today allow any individual and organization across any industry to harness the power of Goldman Sachs’ internal data platform for their own data management and governance needs as well as contribute to the open code base.
