Gentoo Linux, A Powerful Distro For Advanced Users

Filed under
Gentoo

Gentoo Linux is not like other Linux distribution. Where more fashionable distributions worry about fast installation and ease of use, Gentoo worries about efficient compilation and degrees of customization. Gentoo Linux is one of the most advanced operating system in the open source world.

Gentoo is a great way to learn about how your computer works. It is a special, different and powerful Linux distribution. Gentoo is a bare bones minimalist Linux distribution known for being hard to use and one of the hardest distributions to install. It is distributed as free and open source software and follows a rolling release model.

In Gentoo the user must configure everything. Unlike a binary Linux distribution, the source code is compiled locally according to the user’s preferences and is often optimized for the specific type of computer. At the same time a precompiled binaries are available for some larger packages or those with no available source code.

Gentoo-Based Porteus Kiosk 5.2 Brings Linux 5.10 LTS, Updated VAAPI Stack

Filed under
Gentoo

It’s been about five months since the release of Porteus Kiosk 5.1, and Porteus Kiosk 5.2 is here as the second major update to the Porteus Kiosk 5.0 series announced last year in March bringing an updated kernel from the long-term supported Linux 5.10 LTS branch.

Linux 5.10.25 LTS is present in the Porteus Kiosk 5.2 installation images, which adds a new layer of hardware support to the kiosk-oriented distro. Basically, this means that you should now be able to install Porteus Kiosk on hardware where it wasn’t possible using previous releases.

Moving commits between independent git histories

Filed under
Development
Gentoo

PyPy is an alternative Python implementation. While it does replace a large part of the interpreter, a large part of the standard library is shared with CPython. As a result, PyPy is frequently affected by the same vulnerabilities as CPython, and we have to backport security fixes to it.

Backporting security fixes inside CPython is relatively easy. All main Python branches are in a single repository, so it’s just a matter of cherry-picking the commits. Normally, you can easily move patches between two related git repositories using git-style patches but this isn’t going to work for two repositories with unrelated histories.

Does this mean manually patching PyPy and rewriting commit messages by hand? Luckily, there’s a relatively simple git am trick that can help you avoid that.

Ubuntu

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.

  • 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.

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

Filed under
GNU
Linux
Gentoo

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

Filed under
Gentoo

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!

Filed under
Gentoo

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

Filed under
Gentoo

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.)

  • Daiki Ueno: AF_ALG support in GnuTLS

    The Linux kernel implements a set of cryptographic algorithms to be used by other parts of the kernel. These algorithms can be accessed through the internal API; notable consumers of this API are encrypted network protocols such as IPSec and WireGuard, as well as data encryption as in fscrypt. The kernel also provides an interface for user-space programs to access the kernel crypto API. GnuTLS has recently gained a new crypto backend that uses the kernel interface in addition to the user-space implementation. There are a few benefits of having it. The most obvious one is performance improvement: while the existing user-space assembly implementation has comparable performance to the in-kernel software emulation, the kernel crypto implementation also enables workload offloading to hardware accelerators, such as Intel QAT cards. Secondly, it brings support for a wider variety of CPU architectures: not only IA32 and AArch64, but also PowerPC and s390. The last but not least is that it could be used as a potential safety net for the crypto algorithms implementation: deferring the crypto operations to the kernel means that we could have an option to workaround any bugs or compliance (such as FIPS140) issues in the library.

More JingPad A1 Linux tablet detailed revealed ahead of crowdfunding

The JingPad A1 is a tablet with an 11 inch AMOLED touchscreen display, support for digital pen input, and a detachable keyboard that lets you use the tablet like a laptop. It also has an operating system that’s designed for both tablet and laptop mode. That’s because the JingPad A1 will be the first tablet to ship with JingOS, an operating system developed by Chinese company Jingling that’s a custom Linux distribution designed for tablets but capable of running desktop applications (as well as some Android applications). First unveiled in March, the tablet will go up for pre-order soon through an Indiegogo crowdfunding campaign. Jingling hasn’t announced a price yet, but an Indiegogo preview page is now live, and folks who sign up with an email address may be able to save 40-percent when orders open up in May. Read more
