Weerstand van koperdraad – Koperdraad: Gegevens – Wikipedia

Posted by jpluimers on 2025/12/02

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

Is this the ultimate XKCD “Dependency” derivative?

Posted by jpluimers on 2025/11/29

xkcd modern digital infrastructure torn down by a satisfied looking cat

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

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:

Interesting; Meshtastic

Posted by jpluimers on 2025/11/27

ImageOn my list of hardware/software to experiment with is [Wayback/Archive] Meshtastic:

An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices

Via [Wayback/Archive] @jilles_com@infosec.exchange on Twitter: “Will be taking to meshtastic.org Lora 433MHz modules to @hotelhacker. Might be cool if more people could bring some to setup a larger mesh and play with them. amzn.eu/d/aCgULy4“

Products:

For both boards, this holds:

1. The Meshtastic program is not pre-installed on this product. If you need to install, please check the steps:

github.com/geeksville/Meshtastic-Android/blob/master/README.md

github.com/meshtastic/meshtastic-device/releases

2. If GPS does not work, the following situations may occur:

Install the Meshtastic firmware before and now reset the GPS when you switch to another firmware.

Reset steps: github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test

3. If GPS is weak indoors, it can be used outdoors

4. The GPS antenna is not installed stably, you can check if the interface is attached to the GPS antenna

This was a nice idea, but apparently not reaching the target audience:

Some 3 years after ChatGPT was introduced, I wonder if this still holds for current language and knowledge models:

When compiler optimisations cause memcpy undefined behaviour: Fix a crash trying to save an empty AudioStream by hpvb · Pull Request #100422 · godotengine/godot · GitHub

Posted by jpluimers on 2025/11/25

The libc C standard library memcpy function is very fast, but because of that also very dumb and with a list of circumstances where its behaviour is undefined (a great opportunity to introduce vulnerabilities in your code). The specs of those are in [Wayback/Archive] memcpy, memcpy_s – cppreference.com, including:

The behavior is undefined if either dest or src is an invalid or null pointer.

With C compilers becoming smarter and smarter, their optimisations can hide the fact that you call memcpy with parameters causing undefined behaviour.

This is a nice example of that: [Wayback/Archive] Fix a crash trying to save an empty AudioStream by hpvb · Pull Request #100422 · godotengine/godot · GitHub

The change is relatively simple, but hardly shows why the change is there. Only one line got changed in [Wayback/Archive] Fix a crash trying to save an empty AudioStream by hpvb · Pull Request #100422 · godotengine/godot · GitHub

Cory LaViska: “ooh you can create intent links for Bluesky” — Bluesky

Posted by jpluimers on 2025/11/20

A longer while I ago, I could not find a URL that would bring up the BKSY post pop-up.

A while ago, I found out there is a compose intent URL: you can even add a text parameter with URL-encoded content!
