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.

  • Why Not WireGuard

    The latest thing that is getting a lot of attention is WireGuard - the new shooting star in terms of VPN. But is it as great as it sounds? I would like to discuss some thoughts, have a look at the implementation and tell you why WireGuard is not a solution that will replace IPsec or OpenVPN. In this article I would like to debunk the myths. It is a long read. If you are in need of a tea of coffee, now is the time to make it. Thanks to Peter for proof-reading my chaotic thoughts. I do not want to discredit the developers of WireGuard for their efforts or for their ideas. It is a working piece of technology, but I personally think that it is being presented as something entirely different - as a replacement for IPsec and OpenVPN which it simply is not. As a side-note, I think that the media is responsible for this and not the WireGuard project itself. There has not been much positive news around the Linux kernel recently. They have reported of crushing processor vulnerabilities that have been mitigated in software, Linus Torvalds using too harsh language and just boring developer things. The scheduler or a zero-copy network stack are not very approachable topics for a glossy magazine. WireGuard is.

Changing colors and font in a virtual terminal isn't easy (see below). Changing colors and font in a terminal emulator, on the other hand, is just a matter of adjusting preferences in a GUI dialog. Last year, for example, I changed the color scheme in my terminal emulator. Read more

  • Integrating MongoDB with Python Using PyMongo

    In this post, we will dive into MongoDB as a data store from a Python perspective. To that end, we'll write a simple script to showcase what we can achieve and any benefits we can reap from it. Web applications, like many other software applications, are powered by data. The organization and storage of this data are important as they dictate how we interact with the various applications at our disposal. The kind of data handled can also have an influence on how we undertake this process. Databases allow us to organize and store this data, while also controlling how we store, access, and secure the information.

  • PyCon: The Hatchery Returns with Nine Events!

    Since its start in 2018, the PyCon US Hatchery Program has become a fundamental part of how PyCon as a conference adapts to best serve the Python community as it grows and changes with time. In keeping with that focus on innovation, the Hatchery Program itself has continued to evolve. Initially we wanted to gauge community interest for this type of program, and in 2018 we launched our first trial program to learn more about what kind of events the community might propose. At the end of that inaugural program, we accepted the PyCon Charlas as our first Hatchery event and it has grown into a permanent track offered at PyCon US.

  • Using "python -m" in Wing 7.2

    Wing version 7.2 has been released, and the next couple Wing Tips look at some of its new features. We've already looked at reformatting with Black and YAPF and Wing 7.2's expanded support for virtualenv. Now let's look at how to set up debugging modules that need to be launched with python -m. This command line option for Python allows searching the Python Path for the name of a module or package, and then loading and executing it. This capability was introduced way back in Python 2.4, and then extended in Python 2.5 through PEP 338 . However, it only came into widespread use relatively recently, for example to launch venv, black, or other command line tools that are shipped as Python packages.

  • New Python Programmer? Learn These Concepts First.

    As a novice Python developer, the world is your oyster with regards to the type of applications that you can create. Despite its age (30 years—an eternity in tech-world terms), Python remains a dominant programming language, with companies using it for all kinds of services, platforms, and applications. For example, Python lets you create web applications via Django or other frameworks such as Flask. Perhaps you want to create games instead? For that, learn Pygame for 2D games (or Panda3D for 3D). Or maybe you’re more enterprise-minded, and want to create useful utilities (such as automatically cataloguing e-books); in that case, Python works well with frameworks and software such as Calibre.
