This is a really cool interactive [Wayback/Archive] nginx playground!
It starts with a default nginx configuration which you can edit and spins up a docker container for each run showing the results of that configuration.
How cool is that to learn how nginx works (:
This is how I found out about it:

At the time of writing a lot of this might be more recent, but for quite some time codepoints.net had not been updated with code point information newer Unicode releases.
Basically it was stuck at Unicode version 8.0 with some 120k glyphs. At the time of writing Unicode version 15.0 is in beta and the difference between 15.0 and 8.0 is some 24k glyphs.
So I had a quick twitter chat with the author and jotted down the links in this blog post so I won’t forget them.
There I learned it was open source (I think it is the only Unicode codepoint site that is).
Here it goes:

Sometimes you need a relatively low-tech solution for updating.
I will need to give this some thought: [Wayback/Archive] Poor Man’s Auto Update. by Chris Bensen | by Chris Bensen | Jun, 2022 | Medium
Back then I posted some edits on Twitter which by now should be reflected in the script and GitHub repository at [Wayback/Archive] chris-blogs/PoorManAutoUpdate.md at main · chrisbensen/chris-blogs (with script at [Wayback/Archive] chris-blogs/updater.sh at main · chrisbensen/chris-blogs)

Every once in a while, b0rk (Julia Evans, of [Wayback/Archive] wizard zines fame) asks interesting questions like below that results in lot of cool links.
I have blogged assemblies of them before (see for instance Lots of interesting git links via b0rk on Twitter) and this one is no different:
[Wayback/Archive] Julia Evans on Twitter: “what are some helpful programming learning games? thinking of things like mystery.knightlab.com for SQL, and flexboxfroggy.com, and ohmygit.org especially interested in games that have helped you learn something”
The response was overwhelmingly good (I tried to indicate when games are not free or not playable from a web browser). I summarised it below.

Ctrl-Alt-Del will not safely reboot all systems under all circumstances.
If you run Linux, your keyboard has a magic RysRq key (sometimes not marked, but its the same key as the Print-Scrn key) and the Linux kernel is still running not all is lost.
Due to link rot, the archived links are the most recent that have all the comments for [Wayback/Archive] Fix a Frozen System with the Magic SysRq Keys | FOSSwire which amend
You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn’t have installed that bad driver, but you did it anyway.So you reach for the power button.Stop.Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job.
- Hold down the Alt and SysRq (Print Screen) keys.
- While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
- Watch your computer reboot magically.
This 2007 comment makes it easier to remember: REISUB is the reverse of BUSIER:
R E I S U B – is just the word busier in reverse.

Still working on handling open Chrome tabs after having moved in the period that GitLab had quite a few issues causing my PagerDuty alerts to go wild.
Today PagerDuty gave me 7 calls in 4 hours again (see [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@gitlab Since 20240312T1727Z I get PagerDuty alerts from HetrixTools for some pages hosted on GitLab. It would be nice if someone could have a look at gitlab.com/gitlab-com/gl-infra/production/-/issues/17717“).
In adddition I need to check if anything made it to the GitLab issue list from the 20230827 connectivity issues I mentioned at [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “Is it @gitlab hosting having transcontinental issues, or are other continental connections affected as well? These are from two different *.gitlab.io pages as measured via @HetrixTools . No issues are listed at status.gitlab.com“.
Back then, this was the most important one: [Wayback/Archive] GitLab System Status: GitLab.com availability issues – October 30, 2023 15:39 UTC
Likely because of this, wiert.me.gitlab.io had been down for a while as well on 20231031 (see [Wayback/Archive] wiert.me.gitlab.io (Recent History) – HetrixTools down from 2023-10-30T15:24Z until 2023-10-30T16:14Z for 3 + 3 + 11 + 27 = 44 minutes.)
Back then, the hardest part was to quickly find out if there was indeed an issue being investigated at all.
The GitLab status multi-media account on Twitter just points to the status page, which makes it hard to find the underlying issue.
I didn’t archive that one in time, but when I got the alerts it didn’t show anything and when it was resolved it was already beyond the cut-off timestamp to mark it as “same day” and the graph didn’t show much down-time [Wayback/Archive] GitLab System Status graph didn’t show much down-time:

Cool: [Wayback] ShellCheck – shell script analysis tool
ShellCheck finds bugs in your shell scripts
It needs a shebang at the start of a script (like #!/usr/bin/env bash) to recognise the kind of shell, then does amazing analysis.
It is open source at [Wayback/Archive.is] koalaman/shellcheck: ShellCheck, a static analysis tool for shell scripts with excellent documentation including explaining screenshots like
It’s not just available on-line or on the command-line, but also integrates with many code editors (like [Wayback/Archive.is] ShellCheck – Visual Studio Marketplace: Integrates ShellCheck into VS Code, a linter for Shell scripts.) and CI/CD pipelines.
Via: [Wayback] bash – error conditional binary operator expected in compound branch – Unix & Linux Stack Exchange (thanks [Wayback] Cyrus!)
