Sad news about Scott Rifenbark

Filed under
Obits

I'm sorry to have to pass on the sad news that Scott Rifenbark, our
tech writer for the project passed away on Wednesday after a battle
with cancer.

I remember interviewing Scott over 10 years ago when forming a team at
Intel to work on what became the Yocto Project, he was with it from the
start. He warned me he wasn't an entirely traditional tech writer but I
warned we weren't aiming to be a traditional project either. It was a
great match. He stayed with the project ever since in one way or
another, he enjoyed working on the project and we enjoyed working with
him.

Windows 10 vs. Ubuntu Linux Performance On A $199 AMD Ryzen Laptop

Filed under
Graphics/Benchmarks

When carrying out our Windows vs. Linux benchmarks we normally are doing so on interesting high-end hardware but for today's benchmarking is a look at how a $199 USD laptop powered by an AMD Ryzen 3 3200U processor compares between Windows 10 as it's shipped on the laptop against the forthcoming Ubuntu 20.04 LTS Linux distribution.

The $199 AMD laptop being used for testing is the Motile M141, a 14-inch laptop with Ryzen 3 3200U and Vega 3 graphics, 4GB of RAM, 120GB solid-state drive, and 1080p display. This 14-inch Ryzen 3 laptop is currently selling for just $199 USD at Walmart. While never hearing of Motile previously, I decided to go ahead and buy this laptop for some Linux testing... Motile is a private-label brand from Walmart.

Solus Shines With Plasma Desktop Options

Filed under
Linux
Reviews

Solus is one of the leading alternative distros to other more mainstream Linux OSes. The 4.1 upgrade, especially the Plasma edition, clearly set the standard that other Linux distributions should follow.

If you are a gamer, take note of this: Solus 4.1 just made gaming simpler. Solus 4.1 ships with increased file limits to enable ESync support. This release also raises the file limits in the PAM (Pluggable Authentication Modules) package to Lutris' suggested value. This lets you spend less time configuring your system and more time playing games.

LibreRouter: An open-source router that offers GPIO pins in a Raspberry Pi form factor

Filed under
OSS

Single-board computers (SBCs) can not only be used as cost-effective options for developers or for creating retro emulators. On the contrary, they can also serve as routers thanks to their wide range of connection options, while some can offer a lot of performance for their size. The Raspberry Pi has practically pre-configured software solutions to this effect, for example.

Now, a DIY solution has been announced by LibreRouter.org. The LR1 is based on a Qualcomm Atheros QCA9558 MIPI processor that can utilise 128 MB of RAM. The router has built-in Wi-Fi too that supports up to IEEE 802.11 b/g/n, while LibreRouter also offers an optional GPS sensor. Using the two mPCIe slots you can connect powerful network cards or cellular routers, too.

Pentoo – A Security-Focused Linux Distro Based on Gentoo

Filed under
Gentoo
Security

Pentoo is an open-source Live CD and Live USB Gentoo Linux-based operating system designed for experts in the field of penetration testing and security assessment. It is available for both 32-bit and 64-bit architectures and is can be run as an overlay on an existing Gentoo installation.

If you’re not familiar with Gentoo Linux, it is an advanced Linux distro that enables users to compile their operating system from the source in other to enjoy advantages such as applications and optimal performance specific to the computer, to mention a couple.

It does not have an installer and users are to translate the software they want before continuing with the installation. In short, one shouldn’t go near it if they don’t have the perseverance for filing through Linux documentation.

Just like with Gentoo, Pentoo has an advanced Python-based package management system with cool features such as “fake” (OpenBSD-style) installs, system profiles, config file management, safe unmerging, and virtual packages, among others.

/e/OS and the Art of Remote Project Management

Filed under
OS
Android

In this article, we look behind the scenes to understand how the team at /e/OS works!
For those who have not been following up on the developments in the smartphone OS world, /e/ OS is a de-googled, privacy-focused, android-based smartphone operating system. The project is the brain child of Gaël Duval, the man who created Mandrake Linux. /e/OS is forked from LineageOS.
The team did not just stop with the forking. First, they removed the Google calls which were spread all over the source code. Next, they replaced several of the default apps and added FOSS replacements. With a single /e/ account, user data on the phone could be automatically synchronized with ecloud servers. What data was to be synced can be controlled by the user.
By the middle of 2018, the beta version of the /e/OS was ready. /e/OS today supports 91 smartphones. For those who are not comfortable flashing their smartphones, /e/ offers a range of refurbished smartphones, which can be purchased with /e/OS already flashed on them. Currently they are testing Mail-in-your-phone, a service where users who are not confident flashing their own devices, can send it to /e/ and get it flashed!
All this forking, debugging, rewriting and modification requires design, development and testing efforts. After the OS is flashed on smartphones, support for the end users is required.
Lets understand how /e/ manages all these different activities.

  • Text Encoding Menu in 2021

    In mid-January 2021, the Text Encoding menu in Firefox looks like this: Automatic Unicode Western Arabic (Windows) Arabic (ISO) Baltic (Windows) Baltic (ISO) Central European (Windows) Central European (ISO) Chinese, Simplified Chinese, Traditional Cyrillic (Windows) Cyrillic (KOI8-U) Cyrillic (KOI8-R) Cyrillic (ISO) Cyrillic (DOS) Greek (Windows) Greek (ISO) Hebrew, Visual Hebrew Japanese Korean Thai Turkish Vietnamese [...] For users who have telemetry enabled, we collect data about whether the item “Automatic” was used at least once in given Firefox subsession, whether an item other than “Automatic” was used at least once in a given Firefox subsession, and a characterization of how the encoding that is being overridden was determined (from HTTP, from meta, from chardetng running without the user triggering it, from chardetng as triggered by the user by having chosen “Automatic” previously, etc.). If things go well, the telemetry can be analyzed when Firefox 87 is released (i.e. when 86 has spent its time on the release channel). The current expectation for this is 2021-03-23.

  • Fact check: As Wikipedia turns 20, how credible is it?

    Wikipedia, which has been referred to as a world treasure, turns 20 on Friday. According to research conducted over the years — including a scientific study published by the journal Nature in 2005 and a report commissioned by the site's Wikimedia Foundation in 2012 — Wikipedia's entries are comparable in quality to those in prestigious encyclopedias such as Britannica. However, it is difficult to measure the consistency of information that can be altered at any time.

  • Odin is finally pleased so the open-world survival game Valheim releases on February 2 | GamingOnLinux

    Odin has finally had enough sacrifices and shall be releasing Valheim from Iron Gate AB will enter Early Access with Linux and Windows support on February 2. What is it? A brutal multiplayer exploration and survival game set in a procedurally-generated purgatory inspired by viking culture. Battle, build, and conquer your way to a saga worthy of Odin’s patronage! With low-poly artwork and a very flexible building system it looks absolutely brilliant. The early builds they had available were seriously promising back in 2018 so I'm personally excited to see how far they've progress with it in that time.

  • Ravgeet Dhillon: Offline Toast notification in Nuxt/Vue app

    We have often seen apps telling us that “You are offline. Check your network status.”. It is not only convenient to do so but adds to a great UX. In this blog, we will look at how can we display a toast notification in a Nuxt/Vue app whenever the user goes offline or online. This will also help us to understand how to use computed and watch properties together. [...] Hurray! Our toast notifications are working perfectly fine. So using the combined magic of computed and watch properties, we can create outstanding workflows and take our Nuxt/Vue app to next level. If you any doubts or appreciation for our team, let us know in the comments below. We would be happy to assist you.

  • Stephen Michael Kellat: Leveraging LaTeX In This Time

    From time to time I like to bring up fun adventures in LaTeX. In these stranges times in the United States it is important to look at somewhat practical applications beyond the normal reports and formal papers most people think of. With a Minimum Working Example we can mostly look at an idea. The Comprehensive TeX Archive Network has a package known as newspaper which is effectively subject to nominative determinism. You can make things with it that look like newspapers out of the 1940s-1960s in terms of layout. The page on CTAN shows nice examples of its use and provides a nice story as to why the package was created. The example source file on CTAN has a bug in it, though. We're going to make a new one based on it. I am also going to add but not yet utilize the markdown package to the example.

  • About CVE-2020-27348

    Well this is a doozey. Made public a while back was a security vulnerability in many Snap Packages and the Snapcraft tool used to create them. Specifically, this is the vulnerability identified as CVE-2020-27348. It unfortunately affects many many snap packages… [...] The problem arises when the LD_LIBRARY_PATH includes an empty element in its list. When the Dynamic Linker sees an empty element it will look in the current working directory of the process. So if we construct our search paths with an accidental empty element the application inside our Snap Package could be caused to load a shared library from outside the Snap Package’s shipped files. This can lead to an arbitrary code execution. It has been common to put a definition of the LD_LIBRARY_PATH variable into a Snap Package’s snapcraft.yaml that references a predefined $LD_LIBRARY_PATH as if to extend it. Unfortunately, despite this being common, it was poorly understood that SnapD ensures that the $LD_LIBRARY_PATH is unset when starting a Snap Package’s applications. What that means is that where the author tried to extend the variable they have inadvertantly inserted the bad empty element. The empty element appears because $LD_LIBRARY_PATH is unset so the shell will expand it to an empty string.
