Setting Up a Raspberry PI with a German Mac Keyboard – Seaside Testing

Posted by jpluimers on 2025/05/08

[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:

  • from other manufacturers than Apple
  • with other language layouts

I’m not the only one storing tech gadgets in flight cases (:

Posted by jpluimers on 2024/09/05

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:

Raspberry Pi And The Story Of SD Card Corruption | Hackaday

Posted by jpluimers on 2023/10/02

[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:

  1. use good quality power supplies
  2. put write-heavy operations to SSD
  3. if it suits your use-case, use OverlayFS

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.

Rebooting a Linux server unattended – twm’s blog

[WayBack] Rebooting a Linux server unattended – twm’s blog:

/sbin/shutdown -r now

Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

Raspberry Pi 1B OpenSuSE Tumbleweed zypper upgrade problem · GitHub

Posted by jpluimers on 2020/05/25

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.

TL;DR: Raspberry Pi models 1..3 become hotter and hotter under load; no housing gives best cooling.

SSH: Connection Reset by Peer – Server Fault

Posted by jpluimers on 2018/11/22

One occasion I had SSH throw a Connection Reset by Peer on my when was the SD-card of a Raspberry Pi started failing and the ext4 filesystem got mounted in read-only mode.

Then sshd was still listening on port 22, but since it could not write to disk any more, it threw a Connection Reset by Peer to the client.

It was on OpenSuSE Tumbleweed, but would failed just as well using Raspbian.

Lessons learned:

  • IoT hardware will fail.
  • ext4 breaks when the hardware breaks.

Is a raspberry pi 1 good enough for a pihole server? : pihole

Posted by jpluimers on 2018/04/10

Many people use it that way. Which means I can put it on an old Raspberry Pi B+ revision 1.2 board (which Wikipedia indicates as the B 1+ in the Specifications table but as Raspberry Pi 1 Model B+ revision 1.2 in the schematics of connectors).

I might consider DietPi as distribution (which is Debian based) as it is even ligher.

See [WayBackhttps://www.reddit.com/r/pihole/comments/6h39zr/is_a_raspberry_pi_1_good_enough_for_a_pihole/#divw0i5

One more note: I need to check out which Debian base name (which indicates the version) works best as there seemed to be a dnsmasq issue (not archived because discourse hatesdislikes the WayBack machine and Archive.is):

Like Apple, Android and Delphi, they use name based versions of which I always forget the order of. Luckily the source of the below table gets updated over time [2017 Archive.is2018 Archive.is] Debian releases and names – Electric Toolbox Debian releases are named after characters from Toy Story and are frequently referred to with the name rather than the version.:

Version Code name Release date Toy Story character
1.1 Buzz 1996-06-17 Buzz Lightyear
1.2 Rex 1996-12-12 Rex (the T-Rex)
1.3 Bo 1997-06-05 Bo Peep
2.0 Hamm 1998-07-24 Hamm (the pig)
2.1 Slink 1999-03-09 Slinky Dog
2.2 Potato 2000-08-15 Mr Potato Head
3.0 Woody 2002-07-19 Woody the cowboy
3.1 Sarge 2005-06-06 Sarge from the Bucket O’ Soldiers
4.0 Etch 2007-04-08 Etch, the Etch-A-Sketch
5.0 Lenny 2009-02-14 Lenny, the binoculars
6.0 Squeeze 2011-02-06 Squeeze toy aliens
7 Wheezy 2013-05-04 Wheezy the penguin
8 Jessie 2015-04-26 Jessie the cowgirl
9 Stretch 2017-06-17 Rubber octopus from Toy Story 3

MX Backup – Postfix Email Server | samhobbs.co.uk

Posted by jpluimers on 2017/11/09

Interesting as it has steps for both OpenSuSE and Debian each well suited for running on a Raspberry Pi.

[WayBackMX Backup – Postfix Email Server | samhobbs.co.uk

It seems postfix is a lot easier to configure than sendmail so I already like it.

First I need to read a bit more in Postfix greylisting.

I’ll need to catch up on Sam’s other parts with the postfix tag as well:
