When you want to save some money and order a server with only IPv6, you will not be able to access e.g. github from that machine.

You will not be able to reach any service that does not have an IPv6 address. And at the moment, e.g. github.com is one of these.

To test this, try

# ping6 www.github.com

I just randomly gave it another shot and it just ran with Lutris (2.4.2023) - by my mistake the usually necessary patch was not applied and it ran anyway.

A little digging and I found a reddit post. It might very well be they just messed up the anti-cheat-integration (which made it unplayable on Linux so far).

I was kind of disappointed. No coding, no config advice, no german …

Finally the fork is absolete and the orginal i3 has the esthetic gaps between the windows.

There's more to REST than the "200 OK" resonse code.

Apparently when downloading huge files, Chrome cloggs the Buffer memory and causes a loss in performance.

Create ~/bin/free_mem.sh, chmod u+x it and run with sudo

#!/bin/bash
free -h 
sync && echo 3 > /proc/sys/vm/drop_caches 
echo "---"
free -h

Huggingface LLM Chat

Works like Chat GPT, but is open. Yes, you'll experience phantasizing more often but it's for you to play around and involve instead of just consuming a service from a closed source company.

The online version:

Involve in the training of the model:

You can also run it at home, but I have not tried yet.
