Is Fortran better than Python for teaching the basics of numerical linear algebra? β Dr. Jean-Christophe Loiseau
Posted by jpluimers on 2026/01/13
The summary ofΒ [Wayback/Archive] Is Fortran better than Python for teaching the basics of numerical linear algebra? β Dr.Β Jean-Christophe Loiseau is:
- 1-based indexing prevents off-by-1 errors
- structure is key, especially these foundations:
- clear begin/end constructs instead of visual clues
- strong typing
- verbose programming languages are easier to learn than non-verbose ones
Modern Fortran helps a lot here and shows that after the initial 13 year gaps between FORTRAN 77 and Fortran 90, and between Fortran 90 and Fortran 2003 (the ANSI Standard Fortran and Fortran 95 in between versions were just minor updates), Modern Fortran has come a very long way and now as a thriving community and an extensive list of Fortran software and tools.
Other typed languages and tool sets like C# and Delphi come to mind here as well though you need libraries with 1-based data structures to solve the first point.

Empirical units, Ο, π and π (pi, e, and phi)
Posted by jpluimers on 2026/01/09
Being a non-native English speaker and having monaural hearingΒΉ, the first time visiting the USA I thought they mentioned Empirical UnitsΒ² when they tried to explain miles, feet and other measurement units they use on their island.
Then I learned they are in fact United States customary units but in the USA, they actually name those Imperial Units, implying that the UK still has a very strong influence on the USA. In reality, there are differencesΒ³ between Imperial Units and United States customary units to keep things in the USA practical (or lazy if you want), so I will keep calling their system Empirical Units as it is more fit for purpose (can’t name them Freedom Units any more given their Project 2025 regime).
Anyway, quite a while ago there was this cool XKCD “The Maritime Approximation” (image on the right) including only Imperial Units holding for Empirical Units as well: Ο mph β π kn (let’s use ISO unit symbols here, shall we) which is correct to < 0.5%.
Recently, I learned that with the same accuracy, there is a golden ratio between metric and Imperial/Empirical Units: π km = 1 mi, also correct to < 0.5%.
Kevlin Henney wrote two great blog posts on these explaining way more background information:

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):

Missing C3/C4 on IEC 60320 (IEC 320) Reference Chart – IEC 60320 Connectors & Plugs | StayOnline
Posted by jpluimers on 2025/12/29
I do like the [Wayback/Archive] IEC 60320 (IEC 320) Reference Chart – IEC 60320 Connectors & Plugs | StayOnline ΒΉ, but it lacks combo C3/C4 plug/inlet:
C3 C4 From: IEC 60320 – Wikipedia (and yes: I had an old radio in my youth requiring this plug)
I bumped into the reference chart because I forgot the search term IEC 60320, and therefore searching my earlier blog posts on it Β².
I did remember C13/C14 (normal appliance couplers) and C19/C20 (higher power device couplers), so I used the query [Wayback/Archive] c20 c19 amperage – Google Search giving me this table: Read the rest of this entry »

Temperature controlled fans usable for DIGITUS Professional Network Wall Housing – Soho Wall Cabinet: Amazon.de: Computer & Accessories
Posted by jpluimers on 2025/12/26
TL;DR: avoid Digitus AC fans, but use DC case fans with built-in/external temperature controller plus 12V or USB-step-up power supply and optionally fan grilles/meshes.
A while ago, I bought a 7U shallow 19-inch rack cabinet to house some of our network equipment for the offices and other rooms at the top floor: [Wayback/Archive] DIGITUS Professional Network Wall Housing – Soho Wall Cabinet: Amazon.de: Computer & Accessories
Since it was to be mounted in the boiler room, which is on the top floor under a flat roof, it would get warm so I wanted fans installed in it under or over the air vents in the housing (the cabinet is delivered as flat-pack with parts pictured below and requires about half an hour assembly time):
