Ted Ts'o sent out the EXT4 updates today for Linux 6.11. He explained in that pull request:

"Many cleanups and bug fixes in ext4, especially for the fast commit feature. Also some performance improvements; in particular, improving IOPS and throughput on fast devices running Async Direct I/O by up to 20% by optimizing jbd2_transaction_committed()."

Background: I'm not "new" to linux, but this is my first year daily driving it. I have been running Mint on my main PC for a little over a year, and I love it.

My super old chromebook (Acer c720) has reached end of life. It is no longer supported by Google, and will not receive updates. I've toyed with dual-booting it to Linux in the past with Bodhi, but eventually it broke, and I ended up reverting to ChromeOS. That was years ago, and my patience/knowledge has grown, and I'm committed to switching.

So the other day I went ahead and pulled the trigger. I removed the write-protect screw from the Chromebook's motherboard, and installed Debian 12. I really just chose Debian because I already had a flash drive with the ISO on it for a different project (rooting my Dreame vacuum). It also runs GNOME by default, and I had never used that, so I thought it would be worth a try.
Turns out, I didn't mind GNOME, and I really loved the three-finger swipe to switch workspaces. BUT... Th

Ubuntu seems like it has the best compatibility, but any other suggestions for data wrangling, data analysis, data visualization, and machine learning in Julia, Python and R?

New to Linux, running Debian (if that matters), dot files are configuration files, yes? Do I need to explore each app/UI/program to figure out the possible options? Are there any universals in Linux? Across distros?

Thanks!

I am using a Steam Deck with Mullvad VPN WireGuard. I am quite limited with the software I can install without having to reinstall on each update. On each reboot I have to manual turn on the Mullvad VPN and there is no kill-switch. I run the Steam Deck in desktop mode most of the time connected to a monitor.

I tried to set the WireGuard settings to automatically connect, but the settings keep getting reset.

So I am looking for a desktop widget that can run the command:

 bash

    
curl https://am.i.mullvad.net/json

  

This gives me the connection status and extra information.

If you think I am going about this the wrong way, let me know if there is a better way to quickly check my VPN status.
