[Wayback/Archive] Naomi Wu 机械妖姬 on Twitter: “Ok I have a CO2 meter review video coming up but quick summary: Every no-name Aliexpress CO2 meter under $100 sucks. If they say they are NDIR they are probably lying. The @AranetIoT is expensive but worth it. The @TheatreCaps Mini CO2 monitor is an acceptable alternative.” which I saved as a thread at [Wayback/Archive] Thread by @RealSexyCyborg on Thread Reader App.

VN bevestigt: Nederland is op het punt van toegankelijkheid eigenlijk nog een ontwikkelingsland.
Posted by jpluimers on 2024/09/12
Een maand geleden schreef ik Welkom in de onzichtbare vinkjesmaatschappij – Rules by Rosita (want het gaat slecht met mensenrechten voor gehandicapten in Nederland) met daarin de quote [Wayback/Archive] ⭕️twin van Dijk on X: ““Nederland is op het punt van toegankelijkheid eigenlijk nog een ontwikkelingsland…”.
En inderdaad, de VN heeft dit laatste bevestigd:
Het comité zegt uit onderzoek en het bestuderen van data de indruk te hebben gekregen dat mensen met een beperking, en dan met name verstandelijke beperkingen, ‘nog altijd te maken hebben met stigmatisering en discriminatie’.
De opstellers van het rapport vinden dat afspraken uit het VN-verdrag Handicap nog onvoldoende zijn doorgevoerd. In dat verdrag uit 2008 is bepaald dat mensen met een beperking of chronische ziekte moeten net als ieder ander kunnen meedoen
Volgens het VN-rapport moet Nederland bestaande wetgeving dringend ‘systematisch beoordelen’ en in lijn brengen met het verdrag.
De lijst van kritiekpunten en aanbevelingen is lang. Het comité vindt bijvoorbeeld ook dat het schoolsysteem ‘volledig inclusief’ moet worden. Aan het speciaal onderwijs zou daarom een einde moeten komen, stelt het VN-comité.
Het rapport kun je downloaden via [Wayback/Archive] UN Treaty Body Database: CRPD/C/NLD/CO/1 – CRPD_C_NLD_CO_1_59590_E of als Wayback: CRPD_C_NLD_CO_1_59590_E.docx.

View DOM Source bookmarklet
Posted by jpluimers on 2024/09/12
This is cool as it shows the page source not as it was first loaded, but from how it is currently rendered which includes all post-load modifications by any scripts: [Wayback/Archive] View DOM Source bookmarklet.
Via [Wayback/Archive] Martin Splitt on Twitter: “I made a bookmarklet to view the rendered source (aka the DOM) of a page. 👀 🚀 Works with Chrome, Firefox, Safari and possibly others, too. 🌈 Beautifies the code 🎨 Includes syntax highlighting 💻 Get the bookmarklet at 👉 experiments.geekonaut.de/view-dom-source 👈”

GitHub – AnswerDotAI/fasthtml: The fastest way to create an HTML app
Posted by jpluimers on 2024/09/11
The HTMX based [Wayback/Archive] GitHub – AnswerDotAI/fasthtml: The fastest way to create an HTML app
FastHTML is a new next-generation web framework for fast, scalable web applications with minimal, compact code. It’s designed to be:
- Powerful and expressive enough to build the most advanced, interactive web apps you can imagine.
- Fast and lightweight, so you can write less code and get more done.
- Easy to learn and use, with a simple, intuitive syntax that makes it easy to build complex apps quickly.
FastHTML apps are just Python code, so you can use FastHTML with the full power of the Python language and ecosystem.

infinite loop in “LaTeX: A Document Preparation System” by Leslie Lamport, printed in 1994.
Posted by jpluimers on 2024/09/10

Cover of “LaTeX: A Document Preparation System, 2nd edition”, Published by Addison-Wesley Professional (June 30, 1994) © 1994, authored by Leslie Lamport
LaTeX was slightly later than the 1992 Turbo Pascal 7.0 Language Guide having both entry in the manual about Recursion (“recursive loop, see recursive loop”) which of course is similar to “infinite loop” and entries for “infinite loop See loop, infinite” and “loop, infinite See infinite loop”.
So what is LaTeX?
Where Donald Knuth created the typesetting program TeX (visually TeX), Leslie created a set of macros for it, later named LaTeX (visually LaTeX) and wrote the first (still famous) book – cover on the right – on it: [Wayback/Archive] LaTeX: A Document Preparation System by Leslie Lamport, second edition, printed in 1994 back then by Addison-Wesley (now Pearson Education, subsidiary of Pearson plc) with ISBN 9780201529838.
It’s gimmick was at page 252, inside the index referring “infinite loop” to page 252 itself.
Many people keep posting screenshots of the page without referencing where it is from. That’s a bit sad, as these gimmicks are an important part of history where programming books were as much about explaining features of computing environment, as well as explaining underlying concepts like recursion.
So this 2024 post finally made me write this blog post: [Wayback/Archive] vx-underground on X: “HELP!”

Julia Evans (b0rk on Twitter) motivated many people to post their web browser Javascript debugger tip
Posted by jpluimers on 2024/09/10
There are quite a lot of cool responses to b0rk asking this a while back: [Wayback/Archive] 🔎Julia Evans🔍 on Twitter: “does anyone know of a good demo (blog post / video) of how to use a Javascript debugger in a browser to investigate a bug? I’ve used debuggers in C but never Javascript”
Archived just in case I need to do more web development stuff.

YouTube Archived: private Dell video about detecting non-POST issues like motherboard or memory failures
Posted by jpluimers on 2024/09/09
I forgot where I got this video from: [Wayback/Archive] YouTube Archived: private Dell video about detecting non-POST issues like motherboard or memory failures
It came in useful researching beeping pattern combined an amber/orange blinking pattern on one of my 2018 Dell 3060 MFF machines.
TL;DR
NOTE: On any OptiPlex built since 2012 (that is, 7010/9010/9010 AIO), Dell has stopped using all beep codes except for the Memory Failure code. (1, 3, 2, or one beep, then three beeps, then two beeps.) If your computer was built after 2012 and is making any other beep code, contact technical support for further help.
I knew it already needed a new coin cell battery, but that was surely not the only problem with it, and what type of battery it was (TL;DR: CR2032 and likely longer lasting BR2023 will be compatible too).

Iconography of the X Window System: The Boot Stipple | matttproud.com (blog)
Posted by jpluimers on 2024/09/06

The X Windows System starting up with the seminal stipple on the root window and the X_cursor on the pointer.
Oh, the days of /etc/X11/XF86Config frustration (:
Nevertheless, a good tribute to the X Window System, the successor of the W Window System on V Operating System (not to be confused with System V), that turned 40 in June 2024 is [Wayback/Archive] Iconography of the X Window System: The Boot Stipple | matttproud.com (blog).
Via [Wayback/Archive] mtp: “To celebrate the X Window Syst…” – proud.social (image on the right of that post):
To celebrate the X Window System’s 40th birthday, I did a deep dive on something about it: the iconography of its boot-up stipple (that gray pattern you first see as the X Server starts up):
https://matttproud.com/blog/posts/x-window-system-boot-stipple.html
Did you know the stipple has a name, age, and cultural significance to the ecosystem? I’ll share my personal history with it. What’s yours?
(Later forks replaced XF86Config with xorg.conf).
