I’ve got a problem with port forwarding I can’t get working, never had that problem before and I don’t know network stuff well enough to figure it out.
Docs says that CachyOS has UFW firewall enabled by default. You can search how to configure it, it seems quite easy.
Fish is a replacement of bash that’s a bit more user friendly (has some cool auto completion features out of the box and more sane behaviour like handling of spaces when expanding variables). I personally started to use nutshell recently but unlike fish it’s very different from bash.
Starship is a “prompt” for various shells (that bit of text in terminal before you enter the command that shows current user and directory in bash). I haven’t used it but AFAIK it has many features like showing current time, integration with git, etc.
That’s also true, but I have experienced an occasional issues when it would be stuck on downloading some package at 10 KiB/s because of bad mirror. Parallel downloads likely wouldn’t have helped in this case since it would select the same mirror. Obviously both issues need to be fixed though.
