pierogi engineering – YouTube – search – hard drive

Posted by jpluimers on 2026/01/06

The algorithm got me to the first video of this list: [Wayback/Archive] pierogi engineering – YouTube – search – hard drive

It’s similar to a longer second video that also does balancing using the gyroscopic effect of the moving platters.

Nice!

A few pfSense quirks I got used to over the years

Posted by jpluimers on 2026/01/06

Everytime when installing a pfSense router from scratch, I seem to re-learn a few of the below quirks. So it was finally time to document them (:

Quite a few of my pfSense configurations are just doing routing between various networks, should not provide DHCP leases and do not always need or have a WAN connected (i.e. they are LAN-only).

MacOS (at least 2023 and younger): solution for (TrueType) fonts added through MacOS built-in Font Book not showing up in Pages or Preview

Posted by jpluimers on 2026/01/05

It took me a few queries to find the correct online solution for this problem: after adding a TrueType (and it’s extension: OpenType) font using the built-in MacOS Font Book, they do not show up in Pages or Preview, not even after validating the fonts in Font Book.

Solutions:

  1. reboot (found this out myself)
  2. killing the fontd font daemon from the Activity Monitor
  3. restart font daemon (found out via the link below)
    launchctl kickstart -k gui/`id -u`/com.apple.xtyped

The last one does not work on my Apple Silicon machine, the first two work fine.

For Preview, you have to Force Quit it then start it (so it re-opens all the previous files) to take effect.

I needed this, because I

Product Comparison – GL.iNet and their products I have

Posted by jpluimers on 2026/01/05

At the time of writing (during the Covid-19 Pandemic) the [Wayback/Archive] Product Comparison – GL.iNet contains the below products.

I got 3 of them (2 are variations of the same model) and their quality/price ratio is great, even with the prices that risen during the 2020-onwards global chip shortage.

The Lunduke Journal on X: “Another classic UNIX system has died. The final version of HP-UX has, as of 3 days ago, officially hit “obsolescence” and is no longer supported… “

Posted by jpluimers on 2026/01/04

Another classic UNIX system has died.

The final version of HP-UX has, as of 3 days ago, officially hit “obsolescence” and is no longer supported.

While most versions of HP-UX had hit “end of life” some years back, version 11i v3 (specifically for Itanium servers) was still supported.  At least… until the clock struck midnight on New Year’s Eve.

HP-UX joins the likes of IRIX (support ended in 2013).

Luckily there are still a few classic style UNIX systems in production… but the list is growing smaller with each passing year.

Het tekenen van de Eindrekening en verantwoording » Zumpolle Advocaten

Posted by jpluimers on 2026/01/02

Voor mijn link-archief:

Het ondertekenen van de Eindrekening en verantwoording is een vorm van décharge en dat houdt in dat de oude bewindvoerder door de nieuwe bewindvoerder gevrijwaard wordt van aansprakelijkheid voor het gevoerde bewind.

GitHub – spotDL/spotify-downloader: Download your Spotify playlists and songs along with album art and metadata (from YouTube if a match is found).

Posted by jpluimers on 2026/01/01

Need to check the matching algorithm of [Wayback/Archive] GitHub – spotDL/spotify-downloader: Download your Spotify playlists and songs along with album art and metadata (from YouTube if a match is found).

I wanted to download [Wayback/Archive] The Incredits – song and lyrics by Michael Giacchino | Spotify for music practice, but then found Michael listed it on his YouTube channel twice:

A bit later I also found [Wayback/Archive] The Incredits – Transcription (with original score) – YouTube with [Wayback/Archive] The Incredits Sheet Music for Piano, Trombone, Tuba, Flute piccolo & more instruments (Symphony Orchestra) | MuseScore.com

Via [Wayback/Archive] Youtube-dl supports Spotify. How to use it? : youtubedl.

ssl – Why was 398 days chosen for TLS expiration? – Stack Overflow

Posted by jpluimers on 2026/01/01

Cool, since I switched to Let’s Encrypt a long while ago, I missed that various tools now require TLS expiration be no longer than 398 days away (and preferably even 397 days).

So I also missed the reason for that specific number of days. [Wayback/Archive] ssl – Why was 398 days chosen for TLS expiration? – Stack Overflow (thanks [Wayback/Archive] stevendesu and [Wayback/Archive] user10063)

answers it:

366+31+1 = 398 days

It equals one leap year + one month + “a little room to handle the messiness of dates.”

then posts a lot of quotes from references to the history on how that reason came to be. I have archived and listed the links below.

Most of the discussion was during a very hectic time in life: after a single sided bad accident my mentally retarded brother was in and assisting him during his recovery period, I developed cancer and had extensive treatments against it. All the more reason for missing all this:
