Does anyone know how I can set a keyboard shortcut to open a selected file in a particular application? For example, how can I have .html files set to open in a text editor by default, but set a keyboard shortcut to open one in Firefox if it's selected?

I'm using the Nautilus file manager in GNOME 48 on Debian 13

Does anyone know of a desktop client app for Linux which allows for easily switching between accounts?

Does anyone here have any firsthand experience of the pros & cons of home schooling? Whether as a parent, child or friend/family member/neighbour?

Happy New Year ADHDers!

As promised, here are the results of our scientifically rigorous poll about which things are the worst for taking over your dopamine system:

1. Scrolling
2. Someone is wrong on the Internet
3. Phone notifications
4. Video games
5. Maladaptive daydreaming
6. Unfinished projects that should be quick to finish
7. Sleep-deprivation-induced mania
8. Alcohol
9. Reading internet to drown out own thoughts
10. Expensive hobbies

Comment with one of your worst dopamine hijackers; something which takes over and hogs your dopamine system, and on New Years Day I'll go through the comments and rank the top ten on how many upvotes they get and edit this post with the results as well as make a new post. Maybe even make a New Years Resolution based on it!

If there are any duplicates only the one with the most upvotes will be counted. Any comments/replies which are chat or reactions will obviously be disregarded from the final count.

Does anyone know of a good way to sync ebook reading progress between an Android phone and a Kobo Clara HD?

Just today I'm getting errors when trying to install software via apt in Debian 13. Specifically ardour and gnome-boxes. Other packages seem to be unaffected, like gimp and blobwars for example. The errors are all variations of the following:

Err:1 http://deb.debian.org/debian trixie/main amd64 libwebsockets19t64 amd64 4.3.5-1 404 Not Found [IP: 151.101.62.132 80] Error: Failed to fetch http://deb.debian.org/debian/pool/main/libw/libwebsockets/libwebsockets19t64_4.3.5-1_amd64.deb 404 Not Found [IP: 151.101.62.132 80]

Looking online the suggestion seems to be that I might have /etc/apt/sources.list misconfigured. Is it this causing the problem, or something else?

Here is my sources.list

# deb cdrom://[Debian GNU/Linux 13.0.0 _Trixie_ - Official amd64 NETINST with firmware 20250809-11:2>

Any advice?

Thanks!

Pretty much what the title says. Also, how long does it usually last for when it happens?

Is it an ADHD thing to need time alone more than neurotypical people do? And if so, how do make sure you get it?

I haven't been diagnosed with ADHD but am starting to suspect that I have it.

One thing I know about myself is that I REALLY struggle if I can't have time alone and it's also the main thing that I know that the people in my life struggle to accept about me. It makes me feel really bad not getting enough time alone and not feeling like it's OK with other people if I take it.

Not sure if this is something people with ADHD relate to. Maybe you guys can tell me?

Thought experiment:

If the world was going to get reconfigured in 2026 for maximum benefit to people with ADHD, what would it look like?

I've just started using Soulseek and it's great. I want to make sure that I'm being a good neighbour on it - do I need to do anything to ensure that my files are available for others to download? And do I need to structure directories e.g Artist name > Album name or does it work off metadata?

Can anyone offer some advice on getting an 18-month-old to sleep at night?

Until now the three techniques we've had are 1) feeding to sleep on the boob, 2) walking to sleep in the sling and 3) falling asleep in the car. Number 3 is only good for naps in the daytime, number 2 is getting difficult as our kid is getting big and heavy (and is a PITA at night anyway, and number 1 is starting to become less reliable/effective.

What have you learnt about getting kids (particularly this age, if relevant) to sleep?

Many thanks!
