This is a follow-up on Bookmarklet for Archive.is to navigate to the canonical link which can be accessed from multiple URLs, some through redirection:
You can see the difference in these archived links (the navivate was a typo that I only spotted after the original blog post got published):
I wanted a Bookmarklet to find the last link; the one in the referenced blog post didn’t.

Nice videos about USB-C receptacles replacement that might fit old mini-USB and sometimes micro-USB ones.
Before applying, check out the tables in USB hardware: Compatibilities – Wikipedia and the table I copied from USB hardware: connector dimensions – Wikipedia to ensure there is enough space to fit the USB-C receptacle in:

Nice idea: [Wayback/Archive] 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube
It mentions DuPont wire connectors which is colloquial for a common form of jump wires: the ones that can connect to breadboards, or male or female pin headers. Basically a so called “DuPont wire” is an electric wire with a pin header (either male or female) on each end leading to 3 kinds (not counting ones having multiple connectors on each wire) as male – female is the same as male – female:
- female – female
- female – male
- male – male
Being able to group the connector end of multiple jump wires in one enclosing connector for quick opening and closing is a great idea.
Hopefully the 3D printing files will be released somewhere.
One of the comments is also inspiration for a future 3D printing project:

On OpenWRT GL.iNET based devices, the WireGuard client does not restart upon reboot, even if it was started before rebooting.
Hopefully the /usr/bin/wireguard_watchdog script will help with this as others indicates it should.
My first try was no succes, but since it is supposed to run from cron it does no output. The script on GL-SFT1200 firmware version 3.215, script /usr/bin/wireguard_watchdog is different from the one in the OpenWRT repository, so it needs some investigation.
Some links for checking this out:

I had to pick up a package keying in a 6 digit code using the below PostNL UI.
It was horrible. Don’t implement your numeric input UI like this: use a telephone keypad like or calculator numpad like keypad UI.

The summary of [Wayback/Archive] Is Fortran better than Python for teaching the basics of numerical linear algebra? – Dr. 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.

I feel old, because I vividly remember the PCX (1985) graphics file format: it was the defacto standard under DOS.
TIFF (1986) was slightly younger, and came from the scanner background resulting in very large files though unlike PCX (which had lossless compression), TIFF supported both lossless and lossy compression.
On Windows and OS/2, you had BMP (1985, lossless initially only black and white).
All three suffered from the same problems: different implementations causing all sorts of compatibility problems
Those were the reason for the implementation of newer file formats for graphics like JPG (1992, lossy) and PNG (1996, lossless).
