Voor warmteontwikkeling in koperkabel was ik benieuwd wat de weerstand voor diverse diameters was.
Gelukkig heeft de Nederlandse pagina Koperdraad: Gegevens – Wikipedia deze tabel (let op weerstand is per 100m!)¹

Security alarm provider Woonveilig/Egardia really needs to work on their notifications towards end-users: outages are too frequend and not communicationed on to their customers
Posted by jpluimers on 2025/12/01
This was no incident:
[Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “Als zowel @WoonVeilig als @Egardia op 2 verschillende systemen een systeemtest failure geven en de apps 500-errors weet je dat hun infrastructuur plat ligt. Al een paar uur geleden, dus heel benieuwd hoe snel ze hun engineers wakker kunnen bellen.”
One of the problem is that Egardia/Woonveilig sees their social media channels as a broadcast-only. You can for instance se this when searching doing a [Wayback/Archive] egardia – Twitter Search or [Wayback/Archive] woonveilig – Twitter Search: no answers from them.
There were similar incidents in the past which I did not document on Twitter, but this outage was so large I had to documented it. So I started the [Wayback/Archive] Thread by @jpluimers on Thread Reader App with these images:

Is this the ultimate XKCD “Dependency” derivative?
Posted by jpluimers on 2025/11/29
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

Karateka IBM PC Model 5150 Longplay – YouTube
Posted by jpluimers on 2025/11/28
Karateka (which appeared way before the even more famous Prince of Persia which appeared 5 years later) memories of the past, for which I totally agree with the conclusion: the game on Apple ][ was way better:
[Wayback/Archive] 𝔸𝕟𝕒𝕥𝕠𝕝𝕪 𝕊𝕙𝕒𝕤𝕙𝕜𝕚𝕟💾 on Twitter: “@textfiles Jordan’s opinion on the IBM version”
JULY 31, 1986
Just looked at the “final” version of PC Karateka. It seemed OK, I guessed, except for overall sluggishness, frequent disk accesses, and a few minor graphics glitches. Then I booted up the Apple version to compare… and it was so smooth, it made me want to cry.
The PC version is maybe 50% of what it should be. I can’t even tell these guys s what to fix… it’s a million little things, and they’re just not up to the hassle. That kind of attention to detail is why the Apple version took me two years. This version is probably the best I’ll ever get out of them.
You can play the PC version online at [Wayback/Archive] Karateka IBM Version 1986-01-30 (1986-02-04) (ID 0873) : Jordan Mechner : Free Download, Borrow, and Streaming : Internet Archive
Internal Alpha version (1986-01-30) of the IBM port of Karateka by Jordan Mechner.
It was ported to many platforms, and there was a great documentary too. So there are more YouTube links below than [Wayback/Archive] Karateka IBM PC Model 5150 Longplay – YouTube which has this great description:

The Marvin the Paranoid Android 404-text
Posted by jpluimers on 2025/11/27
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:
