Security updates for Tuesday

Who is good for selling laptops that run Linux in the UK nowadays? I like my x220 but it's getting a bit long in the tooth, plus it's quite heavy. I used to use Tier 1 but I've no idea if they're still good.

Basically I want something like a MacBook Neo form factor but running Linux. I don't want to faff around with something that's difficult to get running - whilst I'm capable of tinkering, on this occasion I want something that Just Works.

Giant creature city builder The Wandering Village is getting a watery DLC https://www.gamingonlinux.com/2026/07/giant-creature-city-builder-the-wandering-village-is-getting-a-watery-dlc/

If you ever need to full out a form in a pdf file on #Linux, I recommend using Firefox. Yes, the browser. I installed 4 different recommendations I got on the net and they were all useless or horribly tedious headaches. Firefox was the winner.

I am wary of forums for #Linux / #FOSS (mostly because of obnoxious fossbros berating noobs for fun), so I ask here. I am using Eye of Gnome (47.0) under #Ubuntu 24.04.4 LTS. Until a couple of weeks ago, while scrolling through images in a directory using the left and right arrow keys, I was able to simply hit the "delete" key to delete images I don't need. Now I get the error message "Error on deleting image filename.jpg Couldn't access trash." How can I fix this?

A great example of accessibility features benefitting more than the target audience, a new version of the classic game Nethack, checking for bufferbloat, and Windows 10 limps on in discoveries. Then Félim’s question about the perceived value of open source goes in unexpected directions.

I just managed to create a pipeline and a client for storing DDIs inside of an OCI registry! Now you can do things similar to Universal Blue but with systemd-sysupdate instead and all the benefits that come from it! I'll publish more things and maybe a blog post about how to use it later! Note: This is heavily WIP, but it seems to be working!

#Mastodon tip: There is a way to use only part of a word as a hashtag!

For example, you might want to say the word “toots”, but use the hashtag “toot”.

To do this, place a U+2060 WORD JOINER before the “s” in “toots”. Example: #toot⁠s.

If you're using #X11 or #Wayland (i.e. #Linux or #BSD desktop), you can add the following line to ~/.XCompose to give yourself a keyboard shortcut:

<Multi_key> <w> <j> : "⁠" U2060 # WORD JOINER

Then just type Compose, then W, then J.

Whereas DirtyClone exploits a kernel module (which can be tackled by unloading and blocking it), Bad Epoll (CVE-2026-46242) does not.

If you haven’t seen it:

> Bad Epoll (CVE-2026-46242) is a race-condition use-after-free in the #Linux kernel's epoll subsystem. This bug lets an unprivileged process become root, not only on Linux desktops and servers but also on Android devices.

Linux v7.1, v7.0.10+, v6.18.33+ are fixed (already running on my NixOS VMs, so I did not have to do any updates for this one)

#MSOffice wurde von meinem Computer entfernt.

It's not just #Spectre and #Meltdown — dozens of similar CPU bugs have been discovered since 2018, and they're still being found:

The foundations of modern computing are ricketier than we like to imagine.

In the past, I've always bought a decent computer and held on to it for years and years: it saves money and it's the green thing you do. My main machine right now is seven years old and still going strong. Updating the OS and apps is no problem — I run #Linux. But #CPU bugs make me wonder whether I should replace computers more often for security reasons. I really hope not.

Anyone happen to know what's going on with kernel.org today?

First my RSS reader thought there were some new releases, but they were old 6.15 series ones.

Then I checked the www.kernel.org - it was originally only showing outdated (no longer listed usually) kernel series, e.g. no 6.18.

Now it's gotten up to showing `longterm: 6.18.37 ...` again (after showing earlier 6.18 revisions for that), and *also* shows a `mainline: 6.18 ...` line.

7.0 and 7.1 have gone MIA.

I'm hoping this is just some backend rebuild that they've chosen/had to run on the live service... and not indicative of some compromise with bad actors trying to generate infected tar balls or the like.

Usually like to use librewolf but for some things need a chromium based browser, which ones have support full privacy/ad blockers, no ai, but are otherwise feature comparable with chrome…

auto update is a bonus but not essential, windows, mac, and linux versions needed…

Thanks in advance!

On #Linux how to share package list and env deets across distros & laptops?

Previously I used #Ansible for packages and global config and YADM for local dotfiles.

YADM has worked well. It's basically git for $HOME so there's not much to learn and it's stays in sync.

My Ansible configs quickly and repeatedly drifted out of sync because it's to easy to install something manually and never go back reflect it in Ansible. Cross-distro, things get even hairier.

Today I'm looking at #Nix instead.🧵️

This is cute.
