Forgot to schedule this one when I saw it two weeks ago: [Wayback/Archive] Sweep the Strait.
Apart from demonstrating that Trump never had a plan, does not and will not have a plan, it is cool to see Minesweeper developed in JavaScript, HTML and CSS mapped with some geodata onto a real map of the Strait of Hormuz.
Cool idea!
It has a function Windows 3.x UI with functional menu (Game -> New Game; Help -> How to Play)
At first, I thought the original developer is this:
However, in fact the developer is:

There is no official Ring API. But there are libraries and tools around that can talk to a Ring ecosystem, mostly written in JavaScript or Python.
Some links I found:

A few years back I tweeted [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “@b0rk @jilles_com Acids vs bases.”
It was a kind of tongue-in-cheek reaction (with a way better picture below) to a very valuable post by b0rk (Julia Evans) on both Twitter and Mastodon [Wayback/Archive] Julia Evans on Twitter: “bases” / [Wayback/Archive] Julia Evans: “bases title: bases # we usually…” – Mastodon for two reasons:
- There are various interpretations of bases
- Octal is very important to educate as errors introduced by its support are hard to spot even if you do know about octal.
Back to Julia’s post:

This was the easiest tool to remove HTML from select tags while keeping line breaks: [Wayback/Archive] Online HTML Stripper. Remove HTML and formatting from text.
Especially the client-side on-line tools I tried failed that option:
This just does not work at all for me: [Wayback/Archive] HTML Cleaner (cannot paste HTML text: needs to paste formatted text which does not work with select elements).
Could I have done this on a command-line? Of course, but I don’t need it often enough to warrant investigating and remembering how to do that in an efficient manner.
Queries:

A cool way to unit-test JavaScript code on the browser side is [Wayback/Archive] Getting Started | QUnit:
To get started with QUnit in the browser, create a simple HTML file called test.html and include the following markup:
<!DOCTYPE html>
<meta charset="utf-8">
<title>Test Suite</title>
<link rel="stylesheet" href="https://code.jquery.com/qunit/qunit-2.19.4.css">
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
<script src="https://code.jquery.com/qunit/qunit-2.19.4.js"></script>
</body>
That’s all the markup you need to start writing tests. Note that this loads the library from the jQuery CDN.
I was so glad to find QUnit via the below links as I unconsciously wanted such a thing for a very very long time.
You can either run it locally or remotely or from the jQuery CDN as both it
- is a Node.js module so the source files are all available on the jQuery CDN
- it does not require the Node.js to load so it can run from any location you want (that CDN, locally or another on-line location)

In yesterday’s post Bookmarklet for Archive.is to navigate to the canonical link with the “redirected from” instead of “saved from” I mentioned js-tokenizer for syntax highlighting. When writing that, I didn’t have time to dig deeper, but saved the links for later investigation.
Since I won’t have time to finish writing a complete article on this anytime soon, I decided to just publish the list:

This is a follow-up on Bookmarklet for Archive.is to navigate to the canonical link which can be accessed from multiple URLs, some through redirection:
You can see the difference in these archived links (the navivate was a typo that I only spotted after the original blog post got published):
I wanted a Bookmarklet to find the last link; the one in the referenced blog post didn’t.

From 12ft – Wikipedia:
On July 17, 2025, the News Media Alliance reported that it had taken down the website.
It’s impossible to enjoy the content of online media by paying (for instance because payment systems are not compatible, but also because those media often have region blocks), so this is to longer ladders (and understanding how ladders work):

I have had JavaScript disabled by default for years now, which means that:
- if your site requires JavaScript, I will opt for an alternative
- I will block anything ad related, even if it means I cannot use your site
The reasons are simple:
- JavaScript has become a big security threat over time. Be it tracking (hello fingerprinting!), data leakage, direct attacks, supply chain attacks, sloppy code or other risks, JavaScript is not vulnerable just by itself, but especially the eco systems (hello npm – 2 attacks in September 2025 alone – and advertising networks) using it. Just a few references:
- [Wayback/Archive] The perils of JavaScript: How we’ve broken the internet’s security
- [Wayback/Archive] Most Common Security Vulnerabilities Using JavaScript – SecureCoding
- [Wayback/Archive] Supply Chain Security Alert: Popular Nx Build System Package Compromised with Data-Stealing Malware – StepSecurity
- [Wayback/Archive] Wormable Malware Causing Supply Chain Compromise of npm Code Packages – Arctic Wolf
- [Wayback/Archive] FingerprintJS | Identify Every Web Visitor & Mobile Device
- JavaScript has become a huge resource hog. Disabling JavaScript by default increased the snappiness and battery life of my laptops and smartphones significantly. In addition, it makes it way easier to read region-blocked content. Double win!
The below thread by [Wayback/Archive] Dr. Christopher Kunz (@christopherkunz@chaos.social) – chaos.social sparked me to finally write why and add some relevant links.

Since a few years, YouTube puts annoyingly overlays on top of like the last 5 to 10 seconds of videos often covering valuable content.
Lately – while preparing for concerts – I have watched a lot of score music videos where the end really is very important to me (see the example below), for instance when rehearsing [Wayback/Archive] La Alhambra – Llano – YouTube until the final end.
The solution came from [Wayback/Archive] How do you disable these thumbnails that pop up near the end of videos!? : r/youtube
