Background
Tux Machines is a popular news site focusing on Free/libre and Open Source software, especially GNU/Linux. Founded by Susan (srlinuxx) in 2004, the site aims to share relevant news with its valued community of readers.
Scope of coverage
The site places great focus on GNU, Linux, and other intricate systems that utilise these, such as Android, Chrome OS, and Tizen. Of lesser interest are issues that relate purely to development and Free/Open Source software. Games, applications, instructional posts and proprietary software are habitually covered, but they are grouped and posted only periodically. Tux Machines is primarily focused on Linux, but it occasionally also covers BSD/UNIX, Minix, and lesser known operation systems. Some of our news sources include standards, antitrust and so on.
The Xtra-PC Linux USB-Stick might be your solution if you have problems with your old and slow PC. It's a small flash drive stick and it's using Linux OS to boost you PC's operations. Check out now.
Peter Turczak’s toddler son loves “technical stuff,” especially things like keyboards and computers that adults use. After discussing this with other likeminded technical parents, the idea of giving new life to an old (PS/2 or AT) keyboard as a teaching tool was hatched.
SiFive in cooperation with Tynker and BBC Learning have launched a Doctor Who themed HiFive Inventor Coding Kit. This Initial HiFive Inventor Coding Kit is intended to help kids as young as seven years of age get involved with computer programming through a variety of fun exercises and challenges involving the RISC-V powered mini computer and related peripherals like LED lighting and speaker control.
[...]
So for those looking to get their kids involved with computer programming and looking for an IoT-type device with some fun sensors and various themed exercises to get them experimenting, the HiFive Inventor Coding Kit is worth looking into further. More details on the programming platform can be found via Tynker.com and on the hardware at HiFiveInventor.com. The HiFive Inventor Kit is available from Amazon.com and other Internet retailers for $75 USD.
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.
Security flaws can be incredibly stupid and dangerous. Of course, I’m not judging anyone, we are humans after all. But this little incident is quite funny.
Audiocasts/Shows: Blender 2.91, Server Security, Linux in the Ham Shack and More
Different use cases will have different security requirements but there's a certain base line that every Linux server should be at before you even think of deploying anything further like disabling certain ways to connect to the server and adding some ssh keys.
Hello and welcome to the 387th episode of Linux in the Ham Shack. In this episode, the hosts discuss concepts related to building software from source code. Topics include proper build environments, packages to install for easy building of software, how to get source, commands for building software and much more. We hope you find this talk interesting and informative and we hope you come back for Episode 388.
We would like to introduce you to Davie Street Enterprises (DSE). DSE is a fictitious 100-year-old multinational corporation that is beginning its digital transformation journey. In this post we will lay the groundwork for a series following DSE as an illustration of how some Red Hat customers are preparing for and succeeding at digital transformation to save money, become more efficient, and compete more effectively.
The company isn't real, but its struggle is very real for many organizations. Throughout this series, we will explore the business problems any number of organizations are challenged with and how DSE, with the help of Red Hat and its partners, plan to solve those problems. To start, let’s learn more about DSE, its business, and some of the associates involved in its digital transformation journey.
When reflecting on 2020, I do what many people do and think about what things were like prior to this year. For me, I immediately go back to a spring day three years ago. Red Hat was hosting our EMEA Partner Conference; a mix of distributors, independent software vendors (ISVs), system integrators and solution providers from across the region. Alongside the usual product updates and market insight sessions you might expect, we decided to do a little drumming. A lot of drumming, in fact — 900 people banging bongos and clashing cymbals. Other than the noise, what I remember was the genuine sense of togetherness; embarrassment and egos put to the side in the pursuit of the perfect tempo.
It seems drumming is a good signal of solidarity. Even in a large group, it’s easy to notice someone beating to a different rhythm. Trainers and coaches use this drumming technique frequently to promote unity and coordination. Our coach that day later congratulated me on "having such a tight knit group of employees." When I told him they weren’t our employees but partners from 550 different companies, he couldn’t believe it.
When it comes to performance metrics data collection and visualization on Linux, PCP metrics collection and visualization are key. Red Hat Enterprise Linux (RHEL) 8 provides an excellent framework for collecting performance metrics and visualizing them! The days of poring over command line output to try and figure out what is happening on a system are gone. In this series, I’d like to introduce the power of using Performance Co-Pilot (PCP) and Grafana to visualize system performance data in RHEL.
By default, Performance Co-Pilot is not installed on RHEL 8. We believe in giving users choices and as such, you have to opt-in to using Performance Co-Pilot.
The openSUSE Project welcomes our followers to participate in two planned meetups to discuss results from the End of the Year Community Survey on Jan. 23 and Jan. 30.
Both sessions will start at 13:00 UTC on openSUSE’s Jitsi instance and go for 1:30 hours.
Members of the “let’s improve the openSUSE learning experience” initiative will share results and analysis from the survey.
LF Edge has announced the addition of four new general members (FII, HCL, OpenNebula, and Robin.io) and one new Associate member (Shanghai Open Source Information Technology Association).
Additionally, Home Edge has released its third platform update with new Data Storage and Mult-NAT Edge Device Communications (MNDEC) features.

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.
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 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.
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.
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.
The course of the Raku Programming Language by Andrew Shitov made it to the top 20 of Hacker News and spurred quite a few comments. The first associated Grant Report was also published.
GCC 11 entered its final stage of development today as it works towards releasing around the end of Q1 / early Q2 if their past cadence holds up. Before GCC 11.1 can debut as the first stable version, there are some 60+ "P1" high priority regressions that need to be resolved or otherwise demoted to lesser priority regressions.
GCC 11 release manager Richard Biener this morning announced GCC 11 is now in stage four development meaning only regression fixes and documentation fixes are allowed. As of this morning the code-base is at 62 P1 regressions, another 334 P2 regressions, 35 P3 regressions, and more than 200 regressions of the lower P4/P5 status.
