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.

  • Data centre networking: what is OVS? | Ubuntu

    In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer. It represents the ingress point for all the traffic exiting VMs, and can be used to forward traffic between multiple virtual network functions in the form of service chains. Let’s take a closer look in order to understand what OVS is.

  1. Collaborate on a file using Linux diff and patch

    I edit a lot of text files. Sometimes it's code. Other times it's the written word for role-playing games (RPGs), programming books, or general correspondence. Sometimes it's nice to make a change, but for my collaborator to compare my change with what they originally had written. Many people default to office suites, like LibreOffice, using comments or change tracking features. Sometimes a simpler tool makes more sense, though, and for that, you can look at programming history for tools like diff and patch, which provide standardized formatting for tracking and applying changes to shared files.

  3. Quickemu- Run Windows 11 on Ubuntu 20.04 LTS Linux in few clicks

    o you want to install Windows 10 or 11 on your Ubuntu 20.04 or 22.04 LTS Linux using QEMU-KVM virtual machine? Then here is a tutorial to do that using the command terminal and Quickemu + Quickgui. Although we all have a simple solution that is a virtual box to run Windows 11 virtual machine, what about KVM? Some will say it is not easy to operate because of the command line but no there are few open-source GUI programs to give KVM an easy interface. However, another thing is downloading ISO images of various operating systems including Windows 10 or 11 to use with Virtualbox can be a headache. Hence, to solve all of this, there is a project called QuickEMU with a GUI interface known as QuickGUI. QickEMU uses QEMU_KVM on Linux operating system to run a virtual machine and can easily download all popular operating system Images to install including macOS. Whereas it can be operated via CLI but for ease of usage users can install QuickGUI to download, create, and manage operating systems virtual machines.

  4. Steinar H. Gunderson: Commitcoin

    How do you get a git commit with an interesting commit ID (or “SHA”)? Of course, interesting is in the eye of the beholder, but let's define it as having many repeated hex nibbles, e.g. “000” in the commit would be somewhat interesting and “8888888888888888888888888” would be very interesting. This is pretty similar to the dreaded cryptocoin mining; we have no simple way of forcing a given SHA-1 hash unless someone manages a complete second-preimage break, so we must brute-force. (And hopefully without boiling the planet in the process; we'd have to settle for a bit shorter runs than in the example above.) Git commit IDs are SHA-1 checksums of what they contain; the tree object (“what does the commit contain”), the parents, the commit message and some dates. Of those, let's use the author date as the nonce (I chose to keep the committer date truthful, so as to not be accused of forging history too much). We can set up a shell script to commit with --amend, sweeping GIT_AUTHOR_DATE over the course of a day or so and having EDITOR=true in order not to have to close the editor all the time.

We will use two Ubuntu machines: one as the Rudder root server and the other one as the Rudder node. Note: You must be a root user or have sudo privileges on both machines in order to install the Rudder server and agent.

  8. How to check if packages in RHEL-based Linux distributions have been patched for specific CVEs - TechRepublic

    CVEs (Common Vulnerabilities and Exposures) are constantly being discovered and patched. When discovered, it means a new security flaw exists in either an operating system or a piece of software and should be patched as soon as possible. Fixing the vulnerabilities, of course, is up to the developers. Patching those vulnerabilities, however, is up to the admin (or user). Thing is, you might not know if you're using a piece of software that includes one or more CVEs. How do you uncover this information? Do you have to spend hours researching? Not really. In fact, all you need to know is the CVE you're looking for and the piece of software it affects. With those two bits of information in hand, you can quickly discover if what's installed on your Red Hat Enterprise Linux-based distribution contains that vulnerability. I'm going to show you how to do just that.
