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.

Rufus for linux? Not available, Use these best alternatives

Rufus for Linux, yes, everybody who has ever used this bootable USB creator tool which is only available for Windows, definitely wished to have it for Linux operating systems too. However, although it is not directly available for Linux, we can still use it with the help of Wine software. But again even after installing it using Wine on Ubuntu, in our case, it couldn’t recognize the attached USB drives, which again closed the door for normal users to use Rufus on Linux. Thus in such scenarios what do? Don’t worry. The Rufus is not the only software for creating a bootable USB drives in the world. There are also few other best alternatives to Rufus that we can use easily on Linux operating systems. And here today we will discuss such opensource or free tools for creating bootable drives on Linux Distros. Read more

5 Reasons Purism's Librem Laptops Are More Secure Than Your Notebook

If you're looking for a secure laptop computer, you have several options. Thumb readers, facial recognition, and built-in encryption all offer considerable security. But these features – typically backed up by the operating system – are prone to failure, one way or another. For example, facial recognition can be bypassed using various techniques. Purism is a company that assembles Linux computers, complete with a secure operating system and hardware kill switches. These features – while eschewing potential points of entry found on other laptops – make Purism laptops particularly attractive to any user concerned about online privacy and security. Read more

  • Repurposing the VFD unit from an old Epson POS display using Arduino | Arduino Blog

    For many makers, it’s always fun to take some piece of old technology and give it a new lease on life, especially when the item in question was destined for the landfill. This is what prompted Alastair Aitchison — better known on YouTube as Playful Technology — to grab a deprecated vacuum fluorescent display (VFD) module from an Epson point-of-sale device and interface it with an Arduino Nano as a real-time display. VFDs can be thought of as character LCDs, but rather than having many dot-matrix units that use the alignments of suspended crystals to block light, tiny phosphor crystals light up when a current is applied. The module isn’t driven directly by the Arduino Nano since it requires a far higher voltage so a special display controller chip is integrated, which receives commands/data over an RS-232 port and manipulates the onscreen graphics accordingly. This meant a MAX232 had to be used to convert the Nano’s 5V TTL voltage into the -15V to 15 range.

  • [IBM's IWB:] Why Our Judgements Are Often Flawed and What to Do About It

    A few weeks ago I listened to a very interesting Freakonomics podcast hosted by University of Chicago economist Steven Levitt. In the podcast, Why Our Judgment is Flawed — and What to Do About It, Levitt interviewed Daniel Kahneman about his recent book, Noise: A Flow in Human Judgement, co-authored with Olivier Sibony and Cass Sunstein. Kahneman is Professor of Psychology and Public Affairs Emeritus at Princeton University. In 2002, he was awarded the Nobel Prize in Economics “for having integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty.” Thinking, Fast and Slow, Kahneman’s 2011 bestseller, was about the major discoveries by psychologists and cognitive scientists that have led to our current understanding of judgement and decision-making over the past several decades. Up to the 1970s, the prevailing view among social scientists was that people are generally rational and in control of the way they think and make decisions. It was thought that people only departed from rational behaviors because powerful emotions like fear, hatred or love distorted their judgement. These assumptions were challenged by the pioneering research of Kahneman and his long time collaborator Amos Tversky, who died in 1996. In a series of experiments, they demonstrated that human behavior often deviated from the predictions of the previous rational models, and that these deviations were due to the machinery of cognition, that is, to the biases and mental shortcuts or heuristics that we use for making everyday decisions, rather than to our emotional state.

  • Running the AWSY benchmark in the Firefox profiler — Paul Bone

    The are we slim yet (AWSY) benchmark measures memory usage. Recently when I made a simple change to firefox and expected it might save a bit of memory, it actually increased memory usage on the AWSY benchmark. We have lots of tools to hunt down memory usage problems. But to see an almost "log" of when garbage collection and cycle collection occurs, the Firefox profiler is amazing. I wanted to profile the AWSY benchmark to try and understand what was happening with GC scheduling. But it didn’t work out-of-the-box. This is one of those blog posts that I’m writing down so next time this happens, to me or anyone else, although I am selfish. And I websearch for "AWSY and Firefox Profiler" I want this to be the number 1 result and help me (or someone else) out. The normal instructions
