The internet doesn’t like that I host my own mail. First the domain of my mail-server got deactivated (it‘s running again after a week, yeah). Now the VM is down because there are backend-problems -.-

TIL: Rockman (Megaman) might have been named Rainbow Man because each weapon changed him to another color.

1Password became now LastPass with 1Password X?

My domain is now down for 5 days. In the future I know that I will have a look at the registry before registering a domain and I think to move the service provider where I register my domains. Their reaction times are far too slow…

A reminder: do backup your data. You never know what might happen.

30 minutes from setting the downtimes until both OpenBSD-servers were updated to 6.3 incl all packages. Nice. Only IPv6 does not work as expected. I have to look into that.

And yes, OpenBSD 6.3 got released :)

grep comes really from ed (g/re/p) but sed is the stream editor and is based on qed (quick editor) and ed.

The names of grep (g/re/p) and sed (s/ed) do not really come from ed, do they? Oo

I can recommend Michael W Lucas new book Ed Mastery. Once I had only /bin available and vi was in /use/bin. I wish I had read that book before. Ed is more useful than I thought.

Woohoo, mail works again :) (Even though my domain is not fixed yet… :/ )

Next years April Fools-joke: moving editors around and linking things like vi, vim, nano, emacs et al to ed on selected servers

I don’t know how and why but DNS is utterly broken for my domains. And it even doesn’t matter which dns-servers are responsible. One domain is on Cloudflare and adding a new subdomain doesn’t do anything :(

My domain isn’t resolving and it seems to happen at the registrars level…very big meh…

Each time I have to deal with iptables be it through “iptables” or “firewall-cmd” I really wish I would have pf available…

I have to think about BSD/Linux-sysadmin-Interview questions. That is harder than I expected…and when I google around I have to say that I don’t like questions like “how does sudo work? What are its disadvantages”

I am thinking about inlcuding “pf or iptables?” though ;)

Ich hab jetzt ca ein Dutzend ???-Bücher gelesen. Wow,sind die Hörspiele verkürzt und hui sind die Sachen, die sie noch erleben mal auf nem ganz anderen Level (rausgeschwemmt werden aufs offene Meer, mit Glück auf einer Insel landen und dann ein Segelboot zusammen improvisiert zB)

I was told today that I passed the certification for the internal data protection officer :)

It is always the same: I have a problem in a program, search for a solution, give up and while I write the forum-post to ask people, I see my error and can fix it 🤦‍♂️

I tried now the browser Brave on iOS. I can’t use sites with basic auth and there is no way to get bookmarks from other browsers into it apparently. I am not really sure why I should use it. Do the other content blockers on iOS block so much less than Brave?

What I don’t understand: “Why can’t people can quit Facebook”? There was a time when they joined it for some reason. Why aren’t they able to join another service now. Isn’t it mainly a chicken-and-egg-situation and the unwillingness trying to carry people over to another service?

While learning math I always ask myself: how did someone come up with this stuff? Especially when I look for example at algebraic structures like rings and bodies.
