Here are some of my blog posts on documenting using example domains and example IP-addresses or IP-ranges:
(I really wish that example.org and others would service SMTP with blackhole routing so one can also use it for bogus email addresses in documentation)
The blog posts above were incomplete (IPv6 was missing; IPv4 was not explained), so below are more links that do a better job based on a Tweet from [Wayback/Archive] Julia Evans (@b0rk).

In the past, I used to modify /etc/sysconfig/named and add entries to the NAMED_CONF_INCLUDE_FILES setting, then run /usr/share/bind/createNamedConfInclude
to generate /etc/named.conf.include.
As of OpenSuSE 15.4, /usr/share/bind/createNamedConfInclude has become an empty file and NAMED_CONF_INCLUDE_FILES got removed and NAMED_INITIALIZE_SCRIPTS introduced.
So now I changed my playbooks to manually generate /etc/named.conf.include and include it form /etc/sysconfig/named.
Since I hardly perform these new installations, it took a few years for me to find out about this change. Upgrading existing systems somehow kept the generated file and included it.
Related links with quotes as it was hard to find out what changed and how to work around and I wasn’t the only one bump into issues:

Learned a while ago: if you have the username from a GitHub or GitLab user, you can download interesting that sometimes can make life easier (but not necessarily more secure):
github.com/username.keys gives you their public SSH keysgitlab.com/username.keys gives you their public SSH keysgithub.com/username.png gives you their profile image
And that there are tools like gh, glab and age that can make direct use of them.
I love Twitter, so thanks for these for teaching me these little tricks:

Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:
The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:
When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:

A long while ago, I participated in a Twitter thread that started with a translation of some important accessibility posts by Bianca Prins, then extended it to the concept to archivability:
[WayBack] Thread by @jpluimers: “I am going to first translate this, then extend this to archivability…. @jpluimers […]” #UXdesign #accessibility.
TL;DR
Let’s go

In the past xs4all.nl had a shell server. In the shell you had a WWW directory which was the route of your personal web-site.
For instance, I had a file there in ~jp/WWW/route/route.html which was served at:
Almost 25 years after KPN bought xs4all, it switched off the shell servers and these links, so I was glad with this warning [Wayback/Archive] Koen de Jonge on Twitter: “Morgen stopt #kpn4all met het aanbieden van shellaccess. Wij willen dat met #Protagio ook gaan aanbieden. Wil je ook #shellacces houden, kijk dan snel op: … #eerlijkecloud”

A few of my git repositories and technical surroundings (like pages) should outlast my life expectancy, for instance the ones supporting the IT infrastructure of my mentally retarded brother after I pass away.
Most of the involved repositories have no write-activity (they are either documentation that the people can use after I passed away, or are semi-static web-pages that require TLS in order to keep functioning; GitLab provides an automatic update mechanism for that which is based on Let’s Encrypt).
Summer 2022, GitLab caused quite some stir when they planned to first delete dormant repositories. Links on tose below.
Of course I could move to GitHub, but that lacks access control through project hierarchy provided by GitLab and could implement a similar repository dormancy scheme in the future.
Using an external “keepalive” mechanism only induces a game of walls and ladders [Wayback/Archive] (likely requiring intervention after I die) and also makes the infrastructure more brittle so I proposed a lump sum plan.
Some links for my reminder:
