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

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:

It died, but longer ladders will be there: 12ft – Wikipedia

Posted by jpluimers on 2025/12/31

From 12ft – Wikipedia:

On July 17, 2025, the News Media Alliance reported that it had taken down the website.

It’s impossible to enjoy the content of online media by paying (for instance because payment systems are not compatible, but also because those media often have region blocks), so this is to longer ladders (and understanding how ladders work):

python – Some gists on github have very many forks. How can I find the most recently active and/or heavily modified? – Stack Overflow

Posted by jpluimers on 2025/12/30

Interesting read: there is even an API for it (which you need to be logged on for in order not to get a rate limit): [Wayback/Archive] python – Some gists on github have very many forks. How can I find the most recently active and/or heavily modified? – Stack Overflow

Thanks [Wayback/Archive] Michael Goldshteyn, [Wayback/Archive] rob006, [Wayback/Archive] Chankey Pathak and [Wayback/Archive] ikwyl6 for solving this both for gists and regular github repositories:

Structure and Interpretation of Test Cases • Kevlin Henney • GOTO 2022 – YouTube (hello Leap Years!)

Posted by jpluimers on 2025/12/30

Any session by Kevlin is great, so this is definitely recommended watching: [Wayback/Archive] Structure and Interpretation of Test Cases • Kevlin Henney • GOTO 2022 – YouTube

Via [Wayback/Archive] Ifeora Okechukwu on Twitter: “On the structure and interpretation of test cases: by @KevlinHenney Awesome talk!!! “.

A few takeaways:

  • Kevlin uses the same Leap Year case as I have taught since the mid 1990’s: I like the way we both approach software development, though I can still learn a lot from Kevlin.
  • Non-programmers understand more than you might expect, just like you can get much more from a foreign news paper than you would think at first thought
  • You should know how to draw a Venn diagram with 4 sets allowing *all* combinations of those (search for “Venn’s four-set diagram using ellipses” in the link on the left)
  • Kevlin shows these 4 sets:
    • Common cases
    • Simple cases
    • Boundary cases
    • Edge cases

    The first two and last two sound similar. They aren’t.

  • Wrinkles and various levels of code coverage: don’t fool yourself as that is easy to do
  • The way of thinking is “thorough” (note from self: AI is not thorough, it is statistics)
  • Calendars are difficult (and depending a lot on the period and region their usage are valid for) – I already knew that, but it was good to be reminded off; see presentations by Jon Skeet for more information on it, see the blog tag Jon Skeet, or for instance these links:

rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.

Posted by jpluimers on 2025/12/25

This is actually the WireGuard package you can install on pfSense CE 2.5.2 and higher: [Wayback/Archive] rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.

Note that the source code mentions a lot of web-technologies but that is because the majority of the code is the pfSense plugin. Underneath it pulls the actual build from [Wayback/Archive] git.zx2c4.com/wireguard-freebsd/snapshot which is almost exclusively C code.

Like WireGuardNT on Windows, it uses a high performance kernel mode driver.

25 years ago, around this period, the InterBase 6 / Firebird 1 prerelease gaping security hole was detected: a user politically with password correct would gain database access

Posted by jpluimers on 2025/12/24

Before Firebird version 1.0 got released, a gaping security hole that InterBase introduced in 1994 before InterBase 6.0 (mostly written in C) got open sourced in 2000 was detected by the team that frantically tried the Firebird fork to first get building on various platforms, then released.

It had a maximum CVSS score of 10.0 because it could access the security database in read/write mode, thereby allowing adding users with SYSDBA privileges.

The detection is now about 25 years ago; on 20260109 the publication (by IBPhoenix) of the bug will be 25 years ago too.

So below are some links, including the original InterBase 6 source which was hard to find as the attachments of the original release links had not been archived in the Wayback Machine.

But first some of the code parts, which also shows the source file I did find back:
