I hardly do web development, so every once in a while I encounter something that I forgot about.
In this case it was embedding images with base64 encoding in the HTML of a web page.
The GitHub unicorn page reminded me of that, so I saved it in a gist and a JSFiddle:
You can view the rendered HTML here:

Interesting, as this seems to handle all actions client-side: [Wayback/Archive] GitHub – breakzplatform/downloader.notx.blue
Hosting is at two sites:
The code is a tiny HTML wrapper around about 1000 lines of JavaScript (plus a few hundred lines of minified [Wayback/Archive] GitHub – ffmpegwasm/ffmpeg.wasm: FFmpeg for browser, powered by WebAssembly JavaScript code). Impressive!

[Wayback/Archive] Show HN: Live-updating version of the ‘What a week, huh?’ meme | Hacker News
As a fun evening project, I made a live-updating version of the ‘What a week, huh?’ meme (based on a panel from The Adventures of Tintin comics [1]).
There’s a page for every timeframe:
Current time is determined by a Cloudflare Worker using the request IP (not logged or stored). No JavaScript is sent to the browser.

It was easy to edit the HTML to change the message and CSS for the text dimensions, see the image on the right.
MacOS users will likely recognise the font as it is the Marker Felt font which is included by default on MacOS.
And it would be cool to alter the speech bubbles to be more like the ones Hergé used, see this comment:

Every now and then, documentation in source code requires an ASCII table. Sometimes table cells are spanning multiple rows or/and column.
TL;DR: The tools I tried did not support that, so manual labour is still needed.

Cool post [Wayback/Archive] AbortController is your friend starting with
One of my favorite new features of JS is the humble AbortController, and its AbortSignal. It enables some new development patterns, which I’ll cover below, but first: the canonical demo.
It’s to use AbortController to provide a fetch() you can abort early:
It then continues with a series of nice use cases.
Via [Wayback/Archive] Roderick Gadellaa on Twitter: “Late to the party here (was published in June last yr) but great read if you (like me) missed it”.

Donderdag 7 mei 2026 geeft Jorrit Geels op de NLUUG voorjaarsconferentie in het Van der Valk Hotel Utrecht¹ een presentatie over eenvoudigere ontwerpen, duidelijkere mentale modellen en beter onderhoudbare code.
Hoe je dat krijgt? Zet digitale toegankelijkheid consequent op nummer 1, en de rest volgt.
Het resultaat? Je product wordt voor iedereen beter, waardoor alle gebruikers veel effectiever zijn en je boven je concurrentie uitstijgt.

Amazon has activities spread across many different countries and regions, heck they even own their own toplevel domain .amazon.
Yesterday in Online tools to test JSONPath Queries (plus a small list of Amazon top level domains) I wrote about the JSON parsing I did for Download your Kindle books soon, because Amazon will block them after February 25, 2025 .
The source of that list is [Wayback/Archive] Amazon operating domains by country. · GitHub [Wayback/Archive] in the file amazon-domains.json.
In the meantime, I finally managed to go through a list of old open browser tabs having more of such lists. Here they are:
