I use Jails with Ansible to automate their creation, their lifecycle management and automation of the jailed applications and I highly enjoy, how comfortable and easy it is.

No immutable images, no “Dockerfiles”, no weird volume mounts or image registries and no constant re-creation of images and new deployments just to update something. Just some simple, well isolated operating systems to run my applications in 🙂

I don’t say that Linux containers are bad. There’s for sure situations, where they shine. Just for my personal use-case, they are more effort in comparison to BSD jails and I’m a fan of “using the right tool for a task”

And the idempotent nature of Ansible automation makes it easy to describe them in a declarative way and manage them at scale.

From servers in a data center to desktop computers, many devices communicating on a network will eventually have to filter traffic, whether for security or performance reasons. Bpfilter is a project that allows packet filtering to be done with BPF, which can be faster than other mechanisms. Even small performance improvements in this area can lead to significant gains.

Google Chrome was not following the notification spec on Linux for years. This went unnoticed by most of users as services worked it around to accommodate Chrome.

@dnkl took the stand with his notification service that notifications from Chrome wouldn’t work until they followed the spec. After a few years this led to Chrome getting patched to follow the spec.

I've been talking about it for months, but I finally followed Jami Kettunen's instructions and got Chimera Linux installed in my Yoga Slim 7x ARM laptop.

Windows was crashing every few days (while unattended) with the error "The system has rebooted without cleanly shutting down first. This error is caused because the system stopped responding and the hardware watchdog triggered a system reset." even after a full restore.

I'm hoping Linux is more stable.

Here is a quick useful tip for developers and sysadmins/devops folks. Install `dnf-automatic` package on your RHEL/CentOS/Rocky/Oracle/Fedora or Alma #Linux to automate updates and patching:

sudo dnf install dnf-automatic
sudo systemctl enable --now dnf-automatic.timer

This simple tip can help you manage your packages more efficiently and keep your system up-to-date with less manual intervention, which is especially useful when you are on holidays. See https://www.cyberciti.biz/faq/install-enable-automatic-updates-rhel-centos-8/

Quick tip: You can use the last argument of the previous command at the CLi. The syntax is:
command1 !$

For example, make a new dir:
mkdir foo_dir1

Then:
cd !$

which becomes cd foo_dir1, thus saving you typing time. Give it a try.

You can quickly toggle between your two most recent directories with ‘cd -‘:

If you find yourself frequently jumping back and forth between two directories, stop typing out long paths repeatedly! Simply use the command:
cd -

This command will take you to the directory you were in just before your current one. Executing it again will take you back. It saves me a lot of typing and time so give it a try 😌

Linux removes support for the 486, and now I’m curious what that means for Vortex86 processors

I had to dig through our extensive archive - OSNews was founded in 2007, after all - to see if we reported on it at the time, but it turns out we didn't: in 2006, Intel announced that in 2007, it would cease production of a range of old chips, includi

Our household living room computer runs Debian 12 and KDE and we each have our own sessions and use CTRL-ATL-F7 CTRL-ATL-F8 ... to switch between sessions.
Generally it works really well, but every so often, a Plasma process consumes all the RAM causing the PC to lock up. Sometimes it recovers, but the fastest thing to do is a hard reboot.
Any suggestions how I might find out what is going on and how to fix? The PC is usually so nailed, that is it is not possible to run any commands.

Realize the following; **you** are in control of the fun you have when you are computing.

The only way you can guarantee that is by running an Open Source Operating System on that device.

If you happen to be in a closed Source operating system with an open source kernel {Android} there are ways to dechain yourself fully

They will probably be hard or painful but they are worth the effort.

If it seems to be too hard, plan your next device to be one that is designed to run with an open source operating system especially if you are going to buy your next Android.

First check if your device is supported by an open source operating system, fully supported!, then you buy it.

Make sure that the grip of the closed Source operating system underlords on you is released Free yourself

@graste

I hate that: In the late 90s, the #Linux community was proud to be better at #accessibility than commercial operating systems.

Nowadays, the total lack of it, makes Linux an absolute NoGo for institutional and corporate environments.

I believe that the task of fixing that is too much for a community of volunteers.

If states (or the EU) don't fund the necessary developments, it will be the end of Linux and FOSS in many professional settings.

#openSUSE removes Deepin from #Tumbleweed and later #Leap due to numerous violations of packaging policy.
Sounds probably bad for Deepin users, but what surprised me is this:
"In January 2025, during routine reviews, we stumbled upon the deepin-feature-enable package, which was introduced on 2021-04-27 without consulting us or even informing us."
This package basically asked user permission and then injected D-Bus configs and Polkit policies from custom tarballs to circumvent openSUSE strict policy about new D-Bus and Polkit. Sounds shady, right?
But it has been happening for four years! It seems modern OSes and #Linux in particular are overbloated.
How can we expect normal user to know their system, if even maintainers have no idea what's happening behind the curtains?
It's good to see this resolved at last, but man, four years!
What's funny, this "shady" package description plainly states that it asks the user if they agree to openSUSE security circumvention to install D-Bus configs and PolKit policies.
