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

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

Do WiFi-cables (German: WLAN-Kabel) exist?

Posted by jpluimers on 2025/11/21

There is this German joke about “WLAN-Kabel” (WiFi-cable) ** that goes with #Neuland (Germans mocking about Internet and technology still being uncharted territory*).

Yes, they do!

There is [Wayback/Archive] IWLAN RCoax Cable | Industrial Wireless LAN | Siemens Global:

Posted by jpluimers on 2025/10/27

After having moved, I finally need to take a loog at [Wayback/Archive] GitHub – networkupstools/nut: The Network UPS Tools repository. UPS management protocol Informational RFC 9271 published by IETF at https://www.rfc-editor.org/info/rfc9271 Please star NUT on GitHub, this helps with sponsorships!

It supports a whole range of other UPS vendors, and we have a mix of vendors at home: APC, Cyberpower and Victron.
