Hi! I'm Amit Patel. I explain algorithms and math with interactive web pages (incl. pathfinding, hexagons, procgen maps, voronoi). Wrote Solar Realms Elite; helped w/Barren Realms Elite and Realm of the Mad God. https://www.redblobgames.com/
I made a bookmarklet out of it so that I can use it on any page. I bookmarked:
javascript:(async function(){const {attachEditorToElement} = await import ("https://www.redblobgames.com/mjs/scrubbable-codemirror.js");for (let el of document.querySelectorAll("svg")) attachEditorToElement(el)})()
javascript:(async function(){const {attachEditorToElement} = await import ("https://www.redblobgames.com/mjs/scrubbable-codemirror.js");for (let el of document.querySelectorAll("svg")) attachEditorToElement(el)})()

I've wanted to do the same, and bookmarked nelsonslog.wordpress.com/2023/12/18/m... which points to code from @b0rk.jvns.ca and @tinysubversions.bsky.social
My own archive of tweets
I put my own Twitter archive online, hosted here with individual tweet URLs like here. The “server” is all static HTML but the list of tweets is an infinite scroll thing. Oct 2006 to No…

Thank you Craig! The funny/surprising thing is that when I sat down to write the blog post I felt like I hadn't done much that year. But going through all my notes made me realized I had done plenty. :)

Thanks! It was one of those things I wish I had set up years ago :-) and I am looking forward to being able to use it on future projects.

It's a little bit of a hack but the idea is to replace just the "C" or "F" character at the end of the regexp match with the string "C (113.0°F)" or "F (26.7°C)". That string acts as a single character for text editing purposes.

Thank you for this and the other detailed reports! I have learned so much CSS from them.

In the US we sometimes do something similar to highways. Examples in california:
www.google.com/maps/@37.629... (I-380 west end is a stub left for future expansion)
en.wikipedia.org/wiki/Joe_Col... (I-680, was left for many years, hoping that there would be funding someday to complete them)
