Gentoo vs. Ubuntu Linux Comparison
Submitted by Rianne Schestowitz on Friday 19th of February 2021 03:23:16 AM Filed under


Habit is the enemy of change. If you have been using Linux for a while, you may have gotten used to the distribution it offers. If your situation and computing needs changing, then you should think it over. If not, you might want to consider learning a new system for the benefit of apprehension. Knowledge is a very light burden to bear.
For many users, choosing Gentoo is a giant leap. A leap that they never take but can be a serious mistake if you have important reasons to use your computer or system of computers.

lzip decompression support for xz-utils
As of today, the most common implementation of the LZMA algorithm on open source operating systems is the xz format. However, there are a few others available. Notably, a few packages found in the Gentoo repository use the superior lzip format. Does this mean you may end up having to have separate decompressors for both formats installed? Not necessarily.

Ubuntu Blog: Can AI help redefine the future of finserv?
The last few years has been a time of major disruption in the Finserv sector. Artificial Intelligence (AI) technology has emerged as an important tool for providers of financial products and services to deliver more personalised and more sophisticated services to customers faster. The financial services sector is at the beginning of an exciting journey with AI – a journey that we believe will spark a revolution and redefine financial services. Kris Sharma, Financial Services Lead at Canonical has approached this subject from various perspectives.

New openSUSE Step Project Looks to Build SUSE Linux Enterprise on More Architectures
We’re delighted to announce a new project in the openSUSE Project family called openSUSE Step. openSUSE Step is a community effort to rebuild SUSE Linux Enterprise (SLE) from the released SLE sources packages. This is done openly in the openSUSE instance of the Open Build Service (OBS) with the intention to stay fully binary compatible and to be as closely source-compatible as possible with SLE.

Accelerating Atmospheric Research at NCAR with HPE and SUSE | SUSE Communities
Having lived through many harsh winters in the mountains of Pennsylvania and dangerous hurricanes that have hit the Carolinas, I admire the research involved in monitoring climate change, data simulations and predictive analysis. As one shining example at the center of that research, NCAR (National Center for Atmospheric Research) performs weather modeling to climatology, spanning seconds to centuries. Their research demands high performance, long-term application repeatability and high reliability.
Community is key at all levels, from interoperable software with HPE and SUSE to collaboration with other centers (e.g., NOAA, NASA, DOE). In fact, NOAA’s EPIC (Earth Prediction Innovation Center) relies on Cray supercomputers which are at the heart of its global prediction system. NOAA and NCAR collaborate in producing global weather simulations to predict future climate shifts.
The cohesive platform provided by HPE Cray and SUSE Linux Enterprise enables seamless U.S. and global weather simulations. Today, NCAR’s “Cheyenne” supercomputer enables scientists across the country to study phenomena ranging from weather and climate to wildfires, seismic activity, and airflows that generate power at wind farms. Their findings lay the groundwork for better protecting society from natural disasters, lead to more detailed projections of seasonal and longer-term weather and climate variability and improve weather and water forecasts that are needed by economic sectors from agriculture and energy to transportation and tourism. Later this year, NCAR will make another giant leap forward with a new HPE Cray EX supercomputer with a 19.87 peak petaflops system that will work alongside the “Cheyenne” system.

Best Gentoo Linux Derivatives
Submitted by Rianne Schestowitz on Monday 8th of February 2021 07:19:34 PM Filed under

Getting started with Gentoo requires some knowledge of Linux inner workings. This can be time-consuming and frustrating, especially if you have never done it or you have relied on automated install methods for a long time. With that said, it is worthwhile finding out more about your system. You could find many interesting points that can help your private computing or even your career. Many corporations use the Gentoo base and create an internal distribution. One example is Chromium OS; many others are specialized versions for their needs.

Daniel Lange: Installing System Rescue (CD) to a flash drive
Submitted by Roy Schestowitz on Wednesday 27th of January 2021 03:21:09 PM Filed under


System Rescue, the project formerly known as System Rescue CD, has moved from being based on Gentoo to being built on Arch Linux packages.
With this their ISO layout changed substantially so when updating my trusty recue USB flash drive, I could not just update the kernel, initrd and the root filesystem image as I had typically done every other year before.
The "Installing on a USB memory stick" documentation is good for Windows (use Rufus, it's nice) but rather useless for Linux. They recommend a dd or the fancy graphical version of that, called usbimager.

exGENT Live Distro Makes Gentoo Linux Fun to Use in 2021 with the LXQt Desktop
Submitted by Marius Nestor on Friday 22nd of January 2021 12:42:32 PM Filed under
About eight months since the last update to the exGENT distribution, which aims to offer the Linux community a live and installable operating system based on Gentoo. I’ve highlighted live and installable because Gentoo no longer generates regular live ISO images you can try without installing the system.
The exGENT 2021 release makes things even more interesting since it uses the latest Linux 5.10 LTS kernel series, which automatically translates to better hardware support and support for newer hardware. However, the kernel included in the live system is Linux 5.6.7 and Linux kernel 5.10 LTS will be used in the installed system.

Gentoo 2020 in retrospect & happy new year 2021!
Submitted by Roy Schestowitz on Saturday 16th of January 2021 03:15:11 PM Filed under
2020 has featured a major increase in commits to the ::gentoo repository, and especially commits from non-developers. The overall number of commits has grown from 73400 to 104500 (by 42%), while the number of commits made by non-developers has grown from 5700 (8% of total) to 11000 (10.5% of total). The latter group has featured 333 unique authors in 2019, and 391 in 2020.
The ::guru repository has thrived in 2020. While 2019 left it with merely 7 contributors and a total of 86 commits, 2020 has featured 55 different contributors and 2725 commits. GURU is a user-curated repository with a trusted user model. Come join us!
There was also a major increase in Bugzilla activity. 2020 featured almost 25500 bugs reported, compared to 15000 in 2019. This is probably largely thanks to Agostino Sarubbo’s new tinderboxing effort. The total number of bugs closed in 2020 was 23500, compared to 15000 in 2019.

In a Major Shift, Gentoo-based Sabayon Linux is Rebranding Itself to MocaccinoOS With a Focus on Containerization
Submitted by Rianne Schestowitz on Friday 25th of December 2020 02:59:45 AM Filed under
First of all, many of you might not be familiar with Sabayon Linux and most have probably never heard of it at all. Sabayon Linux is a Gentoo-based Linux distro from Italy. Gentoo is a very different distro because all of the software you install (and all of the updates) are compiled from source on your system. There are no precompiled packages.
Unlike its source, Sabayon is designed to be more user friendly and have a more of an “out of the box” philosophy. It has pre-compiled applications available for quick and easy installation. Sabayon also has its software repo and package manager (Entropy). (So, they are the Manjaro of the Gentoo world.)

Console-bound systemd services, the right way
Submitted by Roy Schestowitz on Thursday 17th of September 2020 09:19:28 PM Filed under
Let’s say that you need to run on your system some sort server software which instead of daemonising, has a command console permanently attached to standard input. Let us also say that said console is the only way for the administrator to interact with the service, including requesting its orderly shutdown – whoever has written it has not implemented any sort of signal handling so sending SIGTERM to the service process causes it to simply drop dead, potentially losing data in the process. And finally, let us say that the server in question is proprietary software so it isn’t really possible for you to fix any of the above in the source code (yes, I am talking about a specific piece of software – which by the way is very much alive and kicking as of late 2020). What do you do?
According to the collective wisdom of World Wide Web, the answer to this question is “use a terminal multiplexer like tmux or screen“, or at the very least a stripped-down variant of same such as dtach. OK, that sort of works – what if you want to run it as a proper system-managed service under e.g. OpenRC? The answer of the Stack Exchange crowd: have your init script invoke the terminal multiplexer. Oooooookay, how about under systemd, which actually prefers services it manages not to daemonise by itself? Nope, still “use a terminal multiplexer”.

Portage 3.0 stabilized
Submitted by Rianne Schestowitz on Monday 7th of September 2020 02:51:39 PM Filed under
We have good news! Gentoo’s Portage project has recently stabilized version 3.0 of the package manager.
What’s new? Well, this third version of Portage removes support for Python 2.7, which has been an ongoing effort across the main Gentoo repository by Gentoo’s Python project during the 2020 year (see this blog post).
In addition, due to a user provided patch, updating to the latest version of Portage can vastly speed up dependency calculations by around 50-60%. We love to see our community engaging in our software! For more details, see this Reddit post from the community member who provided the patch. Stay healthy and keep cooking with Gentoo!

Kernel: Millennium Prize, Compute Express Link 2.0, HP Platform Profile Support
| Open Source Community Critical Of Chessbase, Fat Fritz 2
The development teams behind the two most successful and influential open-source chess programs, Stockfish and Leela Chess Zero, have issued statements denouncing the commercial program Fat Fritz 2 and the company Chessbase that is selling the program for 99,90 euros.
The statements (Stockfish blog, lichess announcement) assert that the engine in Fat Fritz 2 is Stockfish with minimal changes, that Fat Fritz 2 has violated the GNU General Public License under which Stockfish is released, and that Chessbase's marketing has made false claims about Fat Fritz 2's playing strength.
