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

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):

  1. [Wayback/Archive] How DotPe’s ‘Human Error’ Exposed Confidential Customer API Data
  2. [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.…”

  3. Now protected private API

    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

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.

Payload Box

Posted by jpluimers on 2025/02/11

For my link archive: [Wayback/Archive] Payload Box.

It has lots of examples on payloads for various kinds of injections that are excellent teaching material.

Covered are Cross Site Scripting (XSS), SQL Injection, Server Side Template Injection, RFI/LFI, Command Injection, CSV Injection, Directory, Open Redirect and XML External Entity (XXE) Injection.

Got there when inspired by:

If you need to learn ASP.NET core or looking for specific examples, then try GitHub dodyg/practical-aspnetcore repository

Posted by jpluimers on 2025/02/05

[Wayback/Archive] dodyg/practical-aspnetcore: Practical samples of ASP.NET Core 2.1, 2.2, 3.1, 5.0, 6.0 and 7.0 projects you can use. Readme contains explanations on all projects.

By the time you read this, all examples should have been rewritten to use minimal API footprint so it easier to get just the essentials from each example.

Via [Wayback/Archive] dodyg on Twitter: “I just realized this repo has about around 1500 samples in total because for each version of ASP.NET Core the samples get modified in some ways beyond project increment, e.g for .NET 6, all samples gets rewritten to use minimal API.”

A Couple of Quick Bookmarklets For Viewing a Suspended / Deleted Twitter User – ResearchBuzz

The WordPress feature that “beautifies” (malforms!) your Blog text is called `wptexturize`: on WordPress.com you cannot disable it.

Posted by jpluimers on 2025/02/03

Over the years, WordPress started to beautify more and more text thereby malforming many (read thousands) of my older blog posts.

An example is this:

--jeroen

is now rendered as

–jeroen

The two hypen-minus signs or -- have become a en-dash or , not even an em-dash or that is is double the width of an en-dash.

So after figuring out the cause, I asked if one could change it for a WordPress.com blog backed by a premium account: [Wayback/Archive] Jeroen Wiert Pluimers on Twitter: “Hi @wordpressdotcom, how do I globally disable wptexturize for a paid wiert.wordpress.com blog (it has Premium subscription)? Over the years, it has malformed more and more of my text which I don’t want (as it is way too much work to re-visit thousands of blog posts).”

Unbelievably, the answer is no!

So WordPress.com mandatorily changes the display of all your old Premium blog posts and the only solution they offer is to upgrade for another USD ~17 per month to disable it.

Bridgy Fed – bridges to/from BlueSky, Fediverse (including Mastodon) and many web-sites

Posted by jpluimers on 2025/01/29

I bumped into [Wayback/Archive] Bridgy Fed a while ago. The highlights:

Source is written in Python and HTML. It is available from [Wayback/Archive] GitHub – snarfed/bridgy-fed: 🌉 A bridge between decentralized social network protocols.

The blog post re-introducing it: [Wayback/Archive] Re-introducing Bridgy Fed | snarfed.org.

There is docs too: [Wayback/Archive] Bridgy Fed: docs

Bridgy Fed is a kind of a spin-off from the longer existing [Wayback/Archive] Bridgy which has documentation at [Wayback/Archive] About – Bridgy and source code at [Wayback/Archive] GitHub – snarfed/bridgy: 📣 Connects your web site to social media. Likes, retweets, mentions, cross-posting, and more….

Via [Wayback/Archive] Ionica Smeets (@ionica.mathstodon.xyz.ap.brid.gy) — Bluesky who’s primary social media presence is at [Wayback/Archive] Ionica Smeets (@ionica@mathstodon.xyz) – Mathstodon.

I created my [Wayback/Archive] wiert.me profile – Bridgy Fed which resulted in these two entities (that by the time you read this should have some updates):

javascript – Open a URL in a new tab (and not a new window) – Stack Overflow

TL;DR: you can force opening a new Window over a new Tab, but not the other way around.

Background information: [Wayback/Archive] javascript – Open a URL in a new tab (and not a new window) – Stack Overflow.

Any YouTube ID is a YouTube ID which means you can use any shorts ID and music ID to watch as a YouTube URL (adding functionality shorts and music URLs lack)

Posted by jpluimers on 2025/01/24

YouTube has diversified its content separating out YouTube Shorts and YouTube Music.

The main YouTube viewing experience has a few advantages over the other two experiences:

  1. content can be monetised
  2. content can arranged into lists (including Watch Later)
  3. auto-play can be turned off

All below links have the same ID, but the ones with checkmarks can use all the above features whereas the ones with crosses cannot.
