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

I used [Wayback/Archive] How could i get a permanent link for raw file? · community · Discussion #22537 · GitHub to go
The reason I needed it is that for quite a while now, GitHub has started to display PDF files as preview, and modified the download behaviour to get a blob: link instead of the actual raw file download location.
On the to do list:
- figure out the same for raw files in gists
- figure out the same for GitLab
- convert these into Bookmarklets (fiddle with the bold parts in the above URLs)
Thanks [Wayback/Archive] Lotaristo (Czeslaw Meyer) and [Wayback/Archive] byrneh (Hugh Byrne)

Besides the August 2025 XKCD infrastructure dependency inspired cartoon on the right, the more recent and great [Wayback/Archive] XCKD: Dependency derivative below is a monumental piece as it combines the recent:
- fiber outage of the Internet Archive
- DoS of Cloudflare by itself
- AWS us-east-1 dependencies outage
- Crowdstrike DoS of Windows machines
- framework-du-jour mentality in the JavaScript world
- many more¹

A while ago, I mentioned a 404-text simulating the Marvin the Paranoid Android as a side-line on a PlantUML post.
While categorising my ASCII art posts, I came across it, and it was published before I started archiving blog links in the Wayback Machine and Archive.is as much as possible.
Back during categorising, I added a few of those archived links, then made a note to research deeper.
So later, I got to that digging and did some digital spelunking, restored the text from an archived page and the underlying JavaScript code that simulated the text being typed on a “terminal”.
Then I did some more spelunking to the oldest usage I could find.
Here are the results:

While doing some ASCII art blog-post drafts cleanup, I bumped into the (now deleted) [Wayback/Archive] Best 404 page ever? : r/ProgrammerHumor which pointed to the (also now deleted).
I got there via my (not deleted!) blog post Why I like PlantUML.
So I dug up the old archived copy of that PlantUML 404-page and made gist out of it.
I soon realised this was all encoded stuff, seemingly a mix of a ROT13 variation and some other shifting around.
Luckily the original page mentioned in the Reddit post was way easier, so I put that in a gist too.
Bot are below the blog-signature. Enjoy!
Oh, and the full text of course above the signature:

Earlier this year I bumped into [Wayback/Archive] ASCII Art Archive
This brought back instant memories about ASCII art, so in the future expect af few unfinished blog-posts that were in my “if I ever get to it archive” about it.
Let me start with my very limited ASCII art I used in late 1980s and early 1990s newsgroup and LISTSERV mailing list signature I reconstructed from a comp.virus post¹ having some very old contact data²:
o _ _ _ _ _ voice: +31-2522-20908 (18:00-24:00 UTC)

Shortly after that, my main source of income moved from the command-line to GUI based tools, so I temporarily kind of lost interest in command-line tools and customs. In that period FIGlet (see below) got created, which I totally missed (though I vaguely remember the 1.0 version being named newban).
The link at the start of this blog post not only pointed me to FIGlet, but also has a lot of examples (like some [Wayback/Archive] ASCII Art Logos – asciiart.eu) of which many by ASCII artist Joan Stark, and also links to JavaScript based tools:
