GNU/Linux

=> ↺ PC World ☛ Linux overtakes Macs on Steam thanks to the Steam Deck

• No, Macs have never been a serious gamer’s first choice. But when even Linux-based systems are climbing past Apple’s computers on Steam’s hardware list, you start to wonder.

• Steam’s monthly hardware report shows that more gamers are using Linux devices than Apple Macs, to the tune of 1.96 versus 1.84 percent (the vast majority of course run Windows PCs). The explanation? Probably Valve’s own Steam Deck gaming handheld. The breakout device runs on Valve’s custom Linux-based Steam OS and intensely marketed (and praised) over the past year.

Applications

=> ↺ Linux Links ☛ Best Free and Open Source Linux Content Control Software

• These are two areas where parental control software plays an important role in enabling parents to protect their family from undesirable content, and to make sure that the internet does not become an addiction. There are very few Linux content control solutions which are high quality and maintained.

• Here’s our verdict captured in a legendary LinuxLinks-style ratings chart.

Instructionals/Technical

=> ↺ John Goerzen ☛ Try the Last Internet Kermit Server

• What is this mysterious protocol? Who uses it and what is its story?

• This story is a winding one, beginning in 1981. Kermit is, to the best of my knowledge, the oldest actively-maintained software package with an original developer still participating. It is also a scripting language, an Internet server, a (scriptable!) SSH client, and a file transfer protocol.

• And my first use of it was talking to my HP-48GX calculator over a 9600bps serial link. Yes, that calculator had a Kermit server built in.

• But let’s back up and talk about serial ports and Modems.

=> ↺ University of Toronto ☛ On Linux, NFS v4 mounts are a different filesystem type than NFS (v3) mounts

• For more or less historical reasons, we currently use NFS v3 to mount filesystems from our fileservers. We’re likely going to (slowly) move over to NFS v4 (after successful experiments), so I’ve been working on various preparations for that, such as making sure our automounter system doesn’t specifically force NFS v3 but instead leaves it up to the system to pick a version. In the process of this, I’ve discovered a surprise.

• On Linux, NFS v4 mounts have the filesystem type ‘nfs4′, not ‘nfs’; the ‘nfs’ filesystem type is for NFS v3 (and NFS v2, if you’re using that, which you probably shouldn’t be). Linux’s normal ‘mount’ program will accept ‘mount -t nfs …’ and do a NFS v4 mount if the server supports it, but listing mounts with ‘mount -t nfs’ will only list NFS v3 ones, and the actual filesystem type in /proc/mounts (aka /proc/self/mounts) and other things is ‘nfs4′.

=> ↺ Aolium ☛ Try installing from source first

• A good reason to use package managers when installing software is that it normally just works. And while that’s a very compelling reason, I still think developers should first try installing software from source when possible. The two main advantages of installing from source are: learning and control. Control over how the package is built, what’s included, where it goes, how it’s managed and the flexibility to apply patches and versions possibly not available in your package manager.

• Now, I’ll be quick to admit that you probably shouldn’t spend a huge amount of time trying to install something from source. For many packages the best case scenario is a complicated process requiring specific build tools and dependencies with their own complications. The worst case scenario is poor or lacking documentation and no idea how to even get started.

• But, you can try.

=> ↺ University of Toronto ☛ Prometheus scrape failures can cause alerts to be ‘resolved’

• Prometheus expressions act as filters, or to put it another way, we’re doing set operations. What an alert rule expression really yields is some number of individual time series, each with its own set of labels. Each time series will become an alert (with its labels taken from the time series), either a pending alert or a firing alert depending on whether or not the alert rule has a ‘for:’ (see my entry on delays and timings for alerts). As long as the alert rule expression continues to produce that time series, the associated alert will stay active. When the alert rule expression stops producing that time series, the associated alert goes away (unless you’ve set ‘keep_firing_for’ on it).

=> ↺ IT Tavern ☛ Getting started with Fail2Ban on Linux

• I want to show you how to get started with Fail2Ban to keep your Linux servers more secure. For this blog post, I’ve used Ubuntu 22.04 LTS as a reference and will use it to secure my SSH service with iptables as the firewall. I assume that you already installed it on your system.

Desktop Environments/WMs

K Desktop Environment/KDE SC/Qt

=> ↺ Nate Graham ☛ This week in KDE: porting, Dolphin, and KWin

• I wrote about all the porting work done recently for Plasma in yesterday’s Plasma 6 update. That work consumed a lot of time due to a big push to get it all done, so this week there isn’t as much feature work and UI polishing to report. Nevertheless, some good fixes and improvements made it in, especially for KWin and Dolphin!

• Copying and pasting files to the desktop that won’t fit there because there’s not enough space now shows a notification explaining the problem (Thenujan Sandramohan, link)

• In the Plasma Wayland session, cursors now look better when using fractional scale factors (Vlad Zahorodnii, link)

=> ↺ Volker Krause ☛ June/July in KDE Itinerary

• Since the last update two month ago we added new import options, public transport mode preferences and many more improvements to KDE Itinerary, and it got featured prominently on the awesome new KDE for Travelers page.

• The various options to import data into Itinerary have been consolidated behind a single global menu action.

• A new way to import online railway tickets has been added as well. Using the booking reference and passenger name or the corresponding app import URLs we can now retrieve the booking details from the operator directly.

• This is currently only available for Deutsche Bahn and SNCF. For adding more operators we again rely on your input in identifying the corresponding APIs and URLs of operators offering that feature.

GNOME Desktop/GTK

=> ↺ GNOME ☛ Developing in GNOME OS: systemd-sysext

• In the old age, developing the desktop was simple™️. You only had to install a handful of toolchains, development headers, and tools from the distribution packages, run make install, execute say_prayer.sh and if you had not eaten meat on Friday you had a 25% chance for your system to work after a reboot.

• Well, if you are an application developer Flatpak makes this very simple. Applications run against a containerized runtimes, with their own userspace. The only thing they need from the host system is a working Desktop Environment, Flatpak, and Portals. Builder and flatpak-builder along with all the integration we built into the Desktop make sure that it will be a breeze.

• SUSE developer Aleksa Sarai has created Incus, a fork of Canonical’s LXD code, with the backing of the now-former lead developer of the container-manager-cum-hypervisor.

• A month ago, Canonical announced LXD would not be independent any more, and the Ubuntu maker was withdrawing it from the Linux Containers project and taking development in-house.

• Soon afterward at least one potential reason for Canonical’s move became public: the former lead engineer of LXD, Stéphane Graber, declared that he had left the Linux distro developer. He stated he planned to continue contributing to the project and will be working under the handle Zabbly…

=> ↺ Arduino ☛ DIY force feedback steering wheel receives motor from an old power drill

• Racing simulators these days are very good, thanks to incredibly realistic graphics and physics. Developers have recreated the effects of everything from tire composition to asphalt temperature. But a lot of that effort goes to waste when you’re playing with a standard gamepad, because that can’t probably any feedback other than some vibration. To make the most of racing sims, Jason Winfield built a DIY force feedback steering wheel using the motor from an old power drill.

• Force feedback steering wheels act as both input devices and output devices. As input devices, they monitor the angle of the wheel to provide a steering value to the game. As output devices, a motor forces the steering wheel to rotate based on what occurs within the simulation. In a hard turn, it might provide resistance. If you spin out of control, the wheel might move around wildly. Because that has to overcome the player’s own grip on the wheel, the force feedback motor needs a lot of torque and that’s why Winfield chose to scavenge the motor from a power drill.

=> ↺ Hackster ☛ Sine Wave generator

• This project visualizes a sinusoidal function on an OLED screen, and a LED can simulate these fluctuations, with a bit of trigonometry. It is easy to understand the code, although the LED may seem to increase and decrease its brightness, in reality, this process is digital and not analog, using a process called PWM.

• OSI has been celebrating 25 years of Open Source at tech conferences around the world.

=> ↺ Why Open Source Matters [Ed: Microsoft mole, bribed by both Microsoft and GitHub (i.e. Microsoft twice over), cites Asay as authority on "Open Source". Asay brought Microsoft to the OSI after he had attempted to work for Microsoft (job interview). Moles galore.]

• Is it “open source”? The question doesn’t really matter. – Matt Asay When we as an industry talk about whether the term open source matters, we need to talk about that question on more than one level. There’s the obvious question of the licensing for a given project.

=> ↺ Ben Cotton: Does open source matter? [Ed: The person whom IBM fired (he led Fedora) cites Asay, who rejects Open Source (he uses Apple and works for proprietary software companies, has no technical background) as "authority"]

• Matt Asay’s article “The Open Source Licensing War is Over” has been making the rounds this week, as text and subtext. While his position is certainly spicy, I don’t think it’s entirely wrong. “It’s not that open source doesn’t matter, but rather it has never mattered in the way some hoped or believed,” Asay writes. I think that’s true, and it’s our fault.

• To the average person, and even to many developers, the freeness or openness of the software doesn’t matter. They want to be able to solve their problem in the easiest (and cheapest) way. Often that’s open source software. Sometimes it isn’t. But they’re not sitting there thinking about the societal impact of their software choices. They’re trying to get a job done.

Productivity Software/LibreOffice/Calligra

Education

=> ↺ Rlang ☛ Multilingual Publishing

• As global movements, Open Source and Open Science face language-based exclusion as most resources are in English. This affects scientists and research software engineers working in R, particularly those who don’t have English as their first language.

• rOpenSci multilingual efforts aim to lower access barriers, democratize quality resources, and increase the possibilities of contributing to open software and science. We successfully piloted our Spanish-language peer review and the localization to Spanish of our comprehensive guide to software development, with Portuguese translation underway.

FSFE

=> ↺ Daniel Pocock ☛ FSFE admits losing funds from bequest by insulting and ignoring Fellowship representative

• As Fellowship representative, I had tried to start a discussion about these funds at the 2017 annual meeting. I put forward several motions for discussion. Each motion was submitted as a separate topic for the meeting agenda. Spitefully, the FSFE president, Matthias Kirschner, merged all the motions into a single motion and had the group vote it away.

Licensing / Legal

=> ↺ Sentry ☛ Let’s Talk About Open Source

• Yesterday we announced that Codecov is now “Open Source”, and we messed up in two ways:

• We wrongly used the term Open Source; while unintentional, we should have known better

• We let our emotions get the best of trying to explain our position, rather than stepping back and addressing the problem

• I want to talk about both of these, how we made the mistake, why it’s important to us, and what we plan to do about this to improve the conversation in the future.

Programming/Development

• Sadly, it doesn’t work like that. You cannot solve the problem with the same mentality that created it. Sometimes money is not the solution. Sometimes bringing in new people is not the solution. Sometimes, we have to start from the within and be honest about why one environment stayed at point A while others went to point C.

=> ↺ Earthly ☛ An Introduction to Rust Generics

• Rust’s use of generics enables developers to write flexible and reusable code. Generics allow functions, structs, and enums to be defined without specifying the type of data they will operate on. This means that a single implementation can work with various types of data, making the code more versatile. Additionally, generics provide better type safety and reduce the likelihood of errors.xs

=> ↺ Matt Rickard ☛ Focus On What Could Go Right (Not Wrong)

• In startups, focus on what could go right instead of wrong.

• Startups are call options in more ways than one. The extreme downside is capped at zero — the startup fails. You’ve lost time and effort, but the company wasn’t worth much (if anything) in the nascent stages. The fewer users you have, the fewer that will remember the product even existed.

Python

=> ↺ Julia Evans ☛ Behind “Hello World” on Linux

• But behind the scenes, there’s a lot more going on. I’ll describe some of what happens, and (much much more importantly!) explain some tools you can use to see what’s going on behind the scenes yourself. We’ll use readelf, strace, ldd, debugfs, /proc, ltrace, dd, and stat. I won’t talk about the Python-specific parts at all – just what happens when you run any dynamically linked executable.

=> ↺ Seth Michael Larson ☛ Security Developer-in-Residence – Weekly Report #6

• I shared this newly published database with the OpenSSF Vulnerability Disclosures WG and received lots of feedback and tips for managing an OSV advisory database. Madison Oliver of GitHub Security gave advice on being a CNA and guidance for hosting first-party and third-party advisories as a CNA. Also received helpful feedback from Oliver Chang and Andrew Pollock. Thanks everyone!

• Being a participant in the distributed vulnerability database for OSV requires choosing an ID prefix for advisories. I chose PSF as the prefix and the prefix was accepted into the OSV schema specification. After the prefix was selected I configured automation in the database to automatically assign IDs for the PSF prefix.
