[Wayback/Archive] Setting Up a Raspberry PI with a German Mac Keyboard – Seaside Testing.
Reminder to self: figure out where parameters for /etc/default/keyboard are documented in case I want to use USB keyboards:

It was about 2 years ago that Jilles reminded me I had a flight case with gadgets too.
Back when I assembled it in 2018, I had big plans for showing private “cloud” container experimentation and gadget stuff at conferences. Then 2019 kicked in with rectum cancer.
So it was good that he helped me motivating to get it working again, especially as the time around assembling it so much fun and working on it brought back those days.
Here are the pictures:

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).

[Wayback/Archive] Raspberry Pi And The Story Of SD Card Corruption | Hackaday is long and worth reading.
For me the most important bits are how to prevent SD card wear:
The first is always a good idea. It is the primary reason all our electronics live behind a UPS:
In addition, I posted my personal experience (Samsung microSD cards last way longer than SanDisk cards) on Twitter:
[Wayback/Archive] @hackaday I’m have been running a few Raspberry Pi systems with 8-32Gb micro-SD cards as web-dashboard with refreshes every few minutes or so: much write access. When using Sandisk (no matter the type) they last about a year, Samsung (no matter the type) cards last multiple years.

We had a lightning strike in the evening on 20181111 some 50 meters from our home.
It killed immediately killed this (some pictures further below):

/sbin/shutdown -r now
Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

It looks like OpenSuSE has stopped supporting Raspberry Pi 1, so the best likely is to recycle it into a Pi-Hole as basically it’s been dead since mid 2017: [WayBack] Raspberry Pi 1B OpenSuSE Tumbleweed zypper upgrade problem · GitHub.

From [WayBack] ipmi – Linux: Why does Single User mode work on Serial Console but not on the attached Keyboard/Video/Monitor? – Server Fault (slightly edited; thanks Patrick!):
Becauseinithas not spawned off multiple TTYs yet (getty,mgetty, etc), so you only have the primary TTY. The primary TTY is the lastconsole=parameter on the kernel command line. All the console parameters get the output, but only the last one will be able to act as input.
