For my reading list, the various responses to [Wayback/Archive] Julia Evans on Twitter: “is there an easy way (in the browser, at runtime) to generate a call graph of which functions called which other functions in a javascript program?”

A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page
Posted by jpluimers on 2025/04/17
From a quite a while back; apparently it ended up in the drafts in stead of the blog queue:
[Wayback/Archive] Ian Miell on Twitter: “A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page: … The possibilities are dizzying. Also, I’ve thought for a while that if I had to put money on it, SQLite will outlast every other database out there.”
The combination of Emscripten and WebAssembly is cool as it allows you to run C/C++ based code in most Web Browsers at near-native speed (though the standard is open and can just as easily outside that realm).

Some HTTP redirect checking sites compared
Posted by jpluimers on 2025/04/02
Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:
- [Wayback/Archive] SSL Server Test: vems-sassenheim.nl (Powered by Qualys SSL Labs)
- [Wayback/Archive] SSL Server Test: www.vems-sassenheim.nl (Powered by Qualys SSL Labs)
The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:
When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:

Need to write bookmarklet for converting RSS feed URL to PlayerFM import feed URL
Posted by jpluimers on 2025/03/11
Target format:
https://player.fm/importer/feed?url=%s
Where %s is the RSS feed for a podcast as URL encoding.
Example:
https://whycast.podcast.audio/@whycast/feed.xml
becomes
https://player.fm/importer/feed?url=https%3A%2F%2Fwhycast.podcast.audio%2F%40whycast%2Ffeed.xml

Weather info in plain text or JSON
Posted by jpluimers on 2025/03/06
Two sites that can help you out getting weather info on the console:
- wttr.in: [Wayback/Archive] Weather report: not found
- 7timer: [Wayback/Archive] civil.php (680×770)
wttr.in
wttr.in is developed by [Wayback/Archive] Igor Chubin (@igor_chubin) / X and looks at the request header to figure out what kind of output it sends.
It supports various output formats, so on my TODO list is to see how they do their mapping: always an opportunity to learn (it’s based on Python and Go so I am curious what libraries they use as well).
From the documentation:
wttr.in currently supports five output formats:
- ANSI for the terminal;
- Plain-text for the terminal and scripts;
- HTML for the browser;
- PNG for the graphical viewers;
- JSON for scripts and APIs;
- Prometheus metrics for scripts and APIs.
The ANSI and HTML formats are selected based on the User-Agent string.
There are more parameters in the documentation on the main page of the repository and through this command:
curl wttr.in/:help
The idea is derived from [Wayback/Archive] GitHub – schachmat/wego: weather app for the terminal.
Oh: Igor has more repositories at [Wayback/Archive] chubin (Igor Chubin) · GitHub (including [Wayback/Archive] GitHub – chubin/cheat.sh: the only cheat sheet you need which is hosted at [Wayback/Archive] cheat.sh; I thought I had blogged about that before, but found it only in a draft note mentioning that I got it via [WaybackSave/Archive] Nicolas Krassas on X: “The only cheat sheet you need cheat.sh“)
7timer
A 7 timer JSON usage example is at [Wayback/Archive] Get Weather from 7Timer! · GitHub
It has documentation at
- [Wayback/Archive] 7Timer! – numerical weather forecast for anywhere over the world
- [Wayback/Archive] Wiki · Yeqzids/7timer-issues Wiki · GitHub
- [Wayback/Archive] 7Timer! API — Public APIs
Output formats can be chosen from HTML, PNG, XML and JSON.

Unicode subscripts and superscripts: Latin, Greek, Cyrillic, and IPA tables; Source: Small caps: Unicode – Wikipedia
Posted by jpluimers on 2025/03/05
I originally searched for the tables below to see if I could get the visualisations of TeX and LaTeX right for infinite loop in “LaTeX: A Document Preparation System” by Leslie Lamport, printed in 1994..
Didn’t work, neither did using plain html super and subscript. The only thing that worked was using CSS styles (I chose to embed them, as separate CSS files are a huge premium over the WordPress plan), which also preserves actual meaning for screen readers:

Reminder to self: re-check the Dotpe API Security Breach — bool.dev
Posted by jpluimers on 2025/03/04
Still public merchant information
It looks like some store and merchang APIs were not protected back when [Wayback/Archive] Dotpe API Security Breach — bool.dev was published.
Reminder to self: check their status now as I can’t believe their “human error” got fixed properly.
History (reverse chronological order):
- [Wayback/Archive] How DotPe’s ‘Human Error’ Exposed Confidential Customer API Data
- [Wayback/Archive] Deedy on X: “Today, Google-backed DotPe locked down their APIs by rate-limiting by IP on /external/merchant and blocking others. They sent a legal notice to the author before fixing it and haven’t publicly acknowledged the issue at all. Companies must be held accountable for poor security.…”
[Wayback/Archive] Tweet JSON: [Wayback/Archive] GYSlTthakAEoojp.png:orig (2346×1838)
-
Now protected private API
[Wayback/Archive] Deedy on X: “6 hours later, the API is still very much public! …”

Twitter image size suffixes reloaded: pbs.twimg.com URL information
Posted by jpluimers on 2025/02/18
It’s almost
- 8 years ago since I wrote about Twitter image size suffixes – via: Making silly #latex jokes is much more fun than doing final tweaks in my thesis on #coeffects…
- 2 years ago I wrote about Some experience of htmlpreview.github.io as a replacement for rawgit.com
- a day posting about converting a tweet URL to a Tweet JSON URL in Probably many more like these are needed to download Twitter videos: [extractor/twitter] Fix unauthenticated extraction by bashonly · Pull Request #7476 · yt-dlp/yt-dlp
Goal of the current post amend the above posts with information so I can later write a bookmarklet or web-page with JavaScript that – from a x.com or twitter.com – tweet URL can get the JSON, then the images and/or videos in all sizes, then generate a web-page from it for Wayback Machine archival.
