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.

  • Intel teases 'software-defined silicon' with Linux kernel contribution – and won't say why

    Intel has teased a new tech it calls "Software Defined Silicon" (SDSi) but is saying almost nothing about it – and has told The Register it could amount to nothing. SDSi popped up around three weeks ago in a post to the Linux Kernel mailing list, in which an Intel Linux software engineer named David Box described it as "a post-manufacturing mechanism for activating additional silicon features".

Merged on Monday was a patch to enable shader culling for Navi 1x consumer SKUs with no longer limiting it to Navi 2x / GFX10.3 or when using various debug options. This culling was also enabled for Navi 1x GPUs but only for the "Pro" graphics SKUs.

  • Speak to me! – Purism

    My trusty laptop’s speakers gave up the ghost. I don’t like to sit around in headphones all the time, I don’t have any other speakers, and the replacements are still being manhandled by the postman. I’d get used to the austerity if I hadn’t started missing calls from a friend. That’s unacceptable! But what am I supposed to do? Buy extra gadgets just to throw them away after a week? Nope, I’m not that kind of a person. But hey – I have a Librem 5! It has a speaker. It’s open. I have control over it, and I’m a hacker too. So I should be able to come up with a hack to turn it into a speaker for my laptop, right? Pulseaudio to the rescue. I look through the guide. There it is: forwarding audio over a network.

  • How To Install CSF Firewall on Debian 11 - idroot

    In this tutorial, we will show you how to install CSF Firewall on Debian 11.

  • What are the differences between SQL and MySQL | FOSS Linux

    Due to many organizations, businesses, companies, and firms making an online presence, databases have become the core requirement for their daily operations. A database in a layman’s language is defined as a collection of data stored and organized electronically to ensure easy retrieval, access, management, and manipulation of business data. Most business successes depend on databases since they aid in storing essential and relevant data in a central position. Besides, databases also help facilitate communication of crucial business info such as employee profiles, sales transactions, customer profiles, marketing campaigns, product inventory, etc. Furthermore, databases have ensured that the company’s data is secure through various authentication mechanisms like access specifiers, user logins, and sign-ups. This article will talk about the difference between the two popular relational databases SQL and MySQL.

  • LDAP query from Python · Pablo Iranzo Gómez's blog

    Recently, some colleagues commented about validating if users in a Telegram group were or not employees anymore, so that the process could be automated without having to chase down the users that left the company. One of the fields that can be configured by each user, is the link to other platforms (Github, LinkedIn, Twitter, Telegram, etc), so querying an LDAP server could suffice to get the list of users. First, we need to get some data required, in our case, we do anonymous binding to our LDAP server and the field to search for containing the ‘other platform’ links.
