[...], we use a private mail server.

I will always recommend against running your own mail infrastructure. The administrative expense is to high in the long run. Unless you want to employ a 24/7 on-call admin team, Office365 is always the better choice. Email encryption can still be done client side (SMIME/PGP).

That's similar to how I use Twitter.

Private Account, no followers, only selected accounts I follow to keep my feed clean of clickbait, useless discussions and the usual twitter outrage. It's a great tool, but I think I'm not using it as it's supposed to be ;) I'm just not interested in participating in useless discussions with trolls and people who try to sell me their product.

RSS actually meant, mostly, that you had to have something worthy of RSS'ing ... a blog, an article, something.

Exactly this! I really miss the time of the internet before social media, when it was more about quality content then clickbait articles. I was a heavy user of Google Reader until it got shut down, but couldn't find any worthy alternative, so I used Twitter as a news feed reader from then on. It's ok, but it's hard to ignore the noise sometimes.

you send a mail to the displayed address and it will parse the incoming mail and analyzes the message headers. the headers contain valuable information about the authenticity of the mail. If a mail looks authentic to the spam filter, it will be marked with a lower spam score.

Don't get yourself onto spam block lists, which can relatively easy happen if your mail server is misconfigured. You can test the spam-level of your outgoing mail on this site: https://www.mail-tester.com

I'm hosting my mail on my own server with postfix and dovecot for 6 years now. It's running smoothly, but I invested alot of work into it. it was fun to figure out how everything is working, anything I needed to know I had to google and stitch the pieces together for my needs, but it was totally worth it because I learned so much when doing it. Since I know how easy the whole system could fail, I would never run a professional/commercial mail server by myself, not even for a small company. Office365, always!

So google for postfix, dovecot, mysql, dkim, roundcube and figure out how to glue it all together. Advise: start with an unused domain, not with your everyday mail address, migration can be done when everything is tested and running.

Nano is perfect for the casual terminal user, it does its job fine when editing an apache server config file once in a while. But when working on the terminal all day, there's no way around vim, IMO. It's good to memorize some basics (save, quit, search & replace) of vim, because there's always a system where only vi is installed (e.g. ESXi).

Thanks! I'm actually thinking about releasing it as a standalone Jekyll theme some time.

Great work! I did something with a similar approach, although it's just kind of a knowledge base for myself build with Jekyll and a little search function, called "My Sysadmin Cheatsheet": https://docs.j7k6.org

Did it mainly for myself, because I was tired of having to google for the same problem more than once, but decided to make it public to kind of share my knowledge with others.

Privacy is always about trust. I trust Apple (more than others) because they never gave me the impression they are doing anything shady with my personal data behind my back. Unlike Google.

The only reason I'm not using Chromium is that 1Password is not trusting it as a "secure browser".

Whenever I come across one of those articles promoting "use Firefox instead of Chrome" I wonder if I'm the only one having those huge performance issues with Firefox on macOS. I seriously tried to make the switch from Chrome to Firefox a few times in the recent years because of all the dark patterns Google is pushing upon its userbase with Chrome, version after version. But Firefox feels significantly slower, makes the MBP fans go crazy and drains the battery like hell.

I've come to the conclusion that at this point it's no option for me to make the final switch to Firefox, as much as I'd like to. But I try to cut off Google's prying eyes from my browsing behaviour as much as possible:

- uBlock Origin + Privacy Badger is all you need to block the most nasty privacy invaders, seriously.

- I don't use the sync feature.

- I don't use Gmail, so there's no reason to login to my Google account, ever.

- I used Youtube's thumbs-up button as sort of bookmarks for my favorite videos, now I have a bookmarks folder for Youtube videos, which is ok for me, but might not be for everybody.

- automatically clear browsing data after quitting Chrome.

My dream browser would be Firefox with Chromium under the hood, but that's not very likely to happen...

I use `chattr +i` with NFS mountpoints for backups, it prevents the local harddrive from filling up when a network share fails to mount on boot.
