Would anyone know which organizations offer opportunities for teaching Linux classes online & remotely? I am interested in sharing my expertise. I currently live in the GMT+3 time zone but am flexible.

I have experience teaching Intro to Linux Systems Admin & Server management. I’ve successfully trained multi-day/person classes using BBB, Jitsi & Zoom.

If you know of any or need training, pls let me know.

Boosts appreciated!

Can I play games on 🐧 #Linux? Yes you can, and it has never been easier!

Using a #SteamDeck? You are #gaming on Linux already 🚀

#LinuxGaming has entered a whole new era over the past decade. Thousands of popular AAA games run seamlessly on Linux and, in many cases, performance is equal to or even better than on #Windows, especially on older hardware.

Hi all you #freebsd #linux experts: what *nix should I install on a spare MacBook Air I have? I last installed RedHat and Ubuntu over 10 yrs ago on an old PC desktop. I'm comfortable on the cmdline and can do sysadmin stuff, but would like to not have to do much. Will use for general home office tasks and some dev projects, but not a gamer. Looking to this as baby-step in larger move away from big-tech, extractive software.

Mal ne Frage an die ITler hier:
Wo krieg ich günstig einen (Mini)PC der Linux-tauglich ist?

Anständiges RAM, ordentliche Grafikkarte (Bild- und Filmbearbeitung, Diktat, bisschen Zocken), große Festplatte (bin Datenmessie), CD/DVD-Laufwerk. Darf gerne refurbished sein.

Habe vor etwa 10 Jahren aufgehört, mich mit der Materie zu beschäftigen und hab keinen Plan, was heute anständig wäre und woran ich Schrott erkenne.

I 💝 OpenZFS

Working on research for a HPC storage cluster, one of my architecture doc sections quote this information from the wonderful group at Klara:

> OpenZFS In the Wild
>
> .. Lawrence Livermore National Laboratory (LLNL) undertook porting ZFS to Linux, to form the backbone of their Lustre distributed filesystem. They noted that OpenZFS facilitated building a storage system that could support 1 terabyte per second of data transfer at less than half the cost of any alternative filesystem.
>
> Based on the success seen at LLNL, Los Alamos National Laboratory (LANL) started using ZFS as well.
>
> In the latest example, just a few months ago the U.S. Department of Energy’s Oak Ridge National Laboratory announced it had built Frontier, the world’s first exascale supercomputing system and currently the fastest computer in the world, backed by Orion, the massive 700 Petabyte ZFS based file system that supports it. This impressive system contains nearly 48,000 hard drives and 5,400 NVMe devices for primary storage, and another 480 NVMe just for metadata.

Has anyone else noticed Virtualbox since 7.2.x becoming extremely unstable when it comes to running "modern Linux guests" (like Ubuntu 24.04.LTS)? 🤔

(The host is a 64GB Windows 11 machine with only one or two guests running at any given time. None of the guests are given more than 16GB, sometimes it's 6-8GB.)

⚡ The idea of /usr/sbin has failed in practice | cks

｢ programs were more or less shoved in /usr/sbin if developers thought they were relatively unlikely to be used by normal people. But 'relatively unlikely' is not 'never', and shortly after people got told to 'run traceroute' and got 'command not found' when they tried, /usr/sbin (probably) started appearing in $PATH ｣

After 6 years I finally decided to refresh my homelab from a single old, loud and inefficient Proxmox server, to 3 mini desktops in a cluster. My new setup will have 2 identical main nodes, and a smaller 3rd node for quorum and to run Proxmox Backup Server, probably will sync it to a cloud PBS provider. Power consumption should go down to about half or even less, and I'll be able to perform maintenance on the hosts without downtime. #homelab #selfhosting #proxmox #linux #cluster

I have these little Lenovo tiny computers and they keep going unresponsive intermittently. I’m running ProxMox on them as a cluster. The first machine kept dying due to using all RAM available with “ballooning” enabled for a Mincraft VM. The new one to randomly stop responding has a different (weaker) PSU that the eBay seller sent. Any thoughts? Is this normal for these machines? The temperatures seem fine and CPU is barely used. #homelab #selfhosted #proxmox #linux

#AMD #StrixPoint #Linux Performance Comparison One Year After Launch
Overall AMD Strix Point continues performing great on Linux. Some nice performance improvements and power efficiency gains while overall hardware/driver support remains quite mature. Performance of Strix Point remains fantastic with Intel's Lunar Lake competition only going up to 8 cores and the only competition against Strix Point is AMD's own with the incredibly fascinating and powerful #StrixHalo.

Interesting article from The Register on Friday about alternative kernels. As per the article, the topic of other kernels surface again after #Linux developers continue to clash over certain tech like Rust, SystemD, and bcachefs.

The three kernels discussed are Managarm, Asterinas, and Xous. Until stumbling across this article today, I've not heard of any of them. I guess I have some reading ahead of me. The article also mentioned the idea of disgruntled devs possibly forking the Linux kernel - a fascinating and probably confusing experience for a lot of people.

Would certainly be an interesting thought experiment, now giving a valid reason to explicitly list the userland and kernel with which OS you happen to be using, ie Debian GNU/Fork-this, openSUSE GNU/Linux, Gentoo GNU/Asterinas, or whatever.

It also might just be easier and more straightfoward to use #FreeBSD instead. 🤷‍♂️

From the Orca mailing list:

Hey all.

I just landed a refactor in the main branch that impacts the following:

* Key echo (what is spoken when you press keys)
* Character echo (what is spoken when a character is inserted)
* Word + sentence echo (what is spoken as you type)

Hopefully I've broken nothing.

I've also made all the settings associated with these accessible via the
D-Bus Remote Controller. This should make it possible for games to turn
off key echo when keys are used for navigation. Note that this is like
all the other on-the-fly settings, so if you Alt+Tab into another app,
the change won't persist. But as I've mentioned before, and subsequently
documented [1], that is not a D-Bus-specific issue.

Regardless, I'd really appreciate some testing. I didn't realize the
49.0 release is due already....

Thanks!

I've finally been brainwashed by GNOME after all these years and got rid of my system tray extension- relying on apps that support background services and keeping those that don't in another workspace.

Forcing myself for a few days to work with this flow, and I think its clicking what they are going for with no systray support, and I think I prefer it now. So clean. Less distractions.

🙅 Goodbye Forever OPNsense 🙅

It displeases me to finally and heartily say GTFO to OPNsense; to abandon a solid decade of use.

I've had it on everything from embedded arm64 experiments to baremetal with ranges of 10, 25, 40, and 100GbE NICs. I've used all of the core features, built complex global service meshes, H/A systems, etc. I used to love it. I used to pay for it.

OPNsense was great, until it wasn't (starting around the time they axed their use of HardenedBSD), and with each release it gets more convoluted, out of date, tedious to debug, and generally a source of disappointment. The command line controls are anemic, inconsistent, and the lack of unified and useful system state tracking is a source of sailor level obscenities. Also, dear gods get rid of XML configs, no one can parse it without going blind! What is this, SOAP and XML-RPC era nonsense, really? 😠

I do not have time to waste, and I do not say that lightly.

I am never debugging OPNsense ever again, especially not for four hours on a (yesterday) Saturday, and especially not putting off updates in a colo for TWO YEARS because their team decided to break admin group SSH controls, hamper CARP flapping controls, breaking IPMI fencing, and the list goes on. I am done.

What now? Three realistic options.

1) BSD Router Project: I've built custom BSD-RP releases with Poudriere, loved just about everything it offers.
2) VyOS: configurable via CLI in a fraction of the time that was wasted on debugging OPNsense. Solid product, enjoying it more every day.
3) OpenWRT: I build custom releases for NanoPi and Meraki rooted WAPs and SOHO boxes, it's fun, though it's not running my 100G infra.

pve8to9 warned me about pvescheduler service being inactive. One of this service's dependencies, pve-guests, which wasn't listed on 'systemctl list-dependencies pvescheduler', seem to be stuck.

It was stuck cos I think it was waiting for all the autostarting vm's to be running so I started all the vm's and then pve-guests wasn't stuck anymore, and pvescheduler is now running.

I only found out the pvescheduler deps on this post: https://forum.proxmox.com/threads/pvescheduler-is-dead-and-wont-start.120794/post-524782
