Install updates regularly. Don’t install software from unofficial sources. If you see a recommendation like run curl something | sudo bash, ignore it. And, in general, don’t run anything as root unless you understand what you are doing and why this cannot be done without root privileges.

Most of what you enumerated is not a terminal emulator job. There is tmux for multiplexing, search and persistent sessions, for instance. And if you want image rendering, what a hell you use TUI for this? GUI programs can also be controlled with keyboard.

If you mean HTTP server, what you need is a reverse proxy and name-based virtual hosts. I usually use nginx for such tasks, but you may choose another web server that has these features.

There’s no any solution. It is impossible to convert from PDF to any editable format correctly. The exception is a “hybrid PDF” that has an embedded editable document. If you need to edit PDFs that you created yourself, store them in hybrid format.

What do you want to accelerate? And for what you need more than 256 colors?

Are you serious? It’s just a window where text is printed. Use what your DE provides. Now I’m mostly on LXQt, so I use QTerminal. With tiling WMs I prefer urxvt because I don’t need builtin window splitting ans tabs. I can’t imagine what other features may I need.

Or, alternatively, [[:digit:]], and dont’ forget to add a quntifier + to match multiple digits. See documentaion for details.

awk '/^\/dev\/loop[[:digit:]]+/{print}'

No, we already have a package manager.

No, not 30 minutes. For the first time I spent couple of weeks just for reading documentation and experiments. It was about 8 years ago IIRC. But since that time when I need something more complex than install a package or copy a file, I feel myself like a 30-minutes user because it does not work as I expect.

No, I can’t. I use it only occasionally, so I don’t remember everything. But many times configurations didn’t work as described in documentation and I had to find a different way to achieve a required result. Sometimes this behavior changed from release to release. This thing doesn’t seem something that I can rely on. But we use it in our company many years, so switch to another tool would be painful.

You will need many iterations of trial and error. No way.

You can speed up testing your playbook by using Molecule or something similar. Don’t touch your working VMs until you get a service (role) set up correctly in your test environment. If you need to set up multiple services in a single VM, you can automate their deployment sequentially, of course.

P. S. I don’t like Ansible and won’t recommend it because it is full of bugs and non-obvious behavior. However I didn’t investigate alternatives and can’t suggest a better one.

Full code audit is very time consuming. It’s impossible to audit all software someone uses. However if I know nothing about project, I do a short look at the code to understand if it follows best practices or not and make some assumptions about the code quality. The problem is that I can’t do this if I’m unfamiliar with the programming language the project is written in, so in most cases I try to avoid such projects.

ls /usr/share/zoneinfo/Asia | nl

Type 68.

IDK what did you mean by “their own thing”. Even if they created something similar to dkms, it is unlikely that it would conflict with dkms. But anyway it is better to find more information from official source.

popos has their own thing that will conflict with dkms

So you obviously need to manually configure that own thing to build the driver instead of relying on the installer.

Just checked one more time that emails from my server are accepted by Gmail. What am I doing wrong?

the list of the daemons running in docker-mailserver

Awful. Who heeds both rspamd and spamassassin simultaneously? fetchmail and getmail6? More than a half of these components are not required to get a working mail server. But I agree that setting up the another half is rather complicated. So I’m planning to give a try to mox when I’ll need to set up a new mail server.

The most interesting command for the Linux shell is known as Barmin patch.

su -c 'dpkg-reconfigure tzdata'

Why not OpenWrt?
