I used Linux (and some Unix) before systemd was a thing and init scripts are jank. So much boilerplate and that was before things like proper isolation existed and other more modern features.
I don't understand why anyone would want that back.
A replacement of systemd with something else would be fine, but please no more init scripts and pointless run levels.
You are actually correct. I just checked the manifest of RHEL and it provides vim-minimal and not vi like I assumed.
I noticed that it behaves a bit different than the version available on AIX for example which for sure uses real vi, but I never gave it a second thought. Interesting.
No. If you have vim installed that's true on many (some?) systems. As I said some distros have vi available, but not vim which is the annoying part.
There is not really anything to learn. It is just lacking some useful features and shortcuts which make it slower to use. It's still much better than nothing.
Usually my biggest issue is that I am so used to write vim over vi. At least for small edits.
I am surprised that vi is often available, but not vim. It's really annoying on many RHEL based distros, because I am so used to typing vim. Otherwise there is just git I deem essential.
Personally I didn't like Deepin and I didn't really use it for long so I can't say much about it. Anyway, it is part of the the extra repositories of Arch, so you can expect a current and maintained version.
It should be the same for other Arch based distros. Just stay clear of Manjaro. It should not be used by anyone.
In general it is safe to install as many DEs as you want. There is some overlap between (user) configuration files though which might be annoying.
It should be fine to experiment, but you might need to restore some settings afterwards. For daily use I would just stick to one DE. Personally I don't think there is really a reason to use multiple DEs as a single user. It would throw me off and mess with my workflow.
Also keep in mind that many DE also provide a set of default tools which add clutter. So you probably want to keep it low for this reason alone.
Sorry, but no. Resolve certs? Seriously?
I don't care anyway if you wanna start the not an expert argument. What you linked doesn't work either in the modern web so... No, I am out.
Resolve the content of the SSL cert? Sounds like something the CSI writers would say...
No, SSL is actually very good in preventing MITM attacks. That's what alle the CAs are for you trust on your device.
Just no!
I would probably prefer having a headphone jack. I am using wireless buds though. The problem with them is the price. While you can get decent wired earbuds for around $100 or even slightly less you have to pay at least $300 for decent wireless ones. Seriously I tried a few, but they all sounded like absolute garbage. It's probably a cheap DAC in all of them combined with even less available space due to batteries and other electronics.
Another downside is that you can only use them for like 5 hours at a time. It is fine most of the time, but on long train rides I hit the limitation a few times.
Overall I am happy with the wireless ones, they are convenient, but it is really expensive to replace them and you have fewer choices, so having wired headsets as an option would be great.
I never tried wireless Bluetooth interfaces though and I suspect they might be better than the inbuilt jack of phones which would make them obsolete in my opinion.
I almost forgot it existed. It was a slight improvement, but with a whole bunch of new problems (most notable race conditions which were never fixed) and it was made obsolete by systemd.
It was a good evolutionary step only used by Ubuntu iirc. It was better at that time than the previous init system, but not more than that and it never found wide adaption.
