Self-OH: Running Kubernetes services is more "Infrastructure as Yaml" than "Infrastructure as Code".

Trostpreis: ich hab zwar Influenza, aber immerhin nichts was mit Influencern zu tun hat.

It took a long road, but today I found the first "in-the-wild" usage of ESP32 BT/WiFi controllers in medical devices.

The quality of those devices is utterly ridiculous and "well"-designed, I consider it an insult to the whole ESP product line.

The temptation of having a lot of quick wins in a PoC vs. the tedious work of implementing a proper, reusable ESP32 component first.

The struggle is real.

Mood: listening carefully to the computer's fans spinning duration and pattern to determine if build of firmware succeeds.

Funny Bluetooth quirks: holding the ESP32 in your hand's palm increases response time from previously maximum of ~200ms up to nearly two seconds.

But only on the wheelchair drive of both that's farther away from the ESP.

I just posted the script with all the content I intended to talk about in my #39c3 talk last weekend on Github:

https://github.com/roll2own/m5squared-resources/blob/main/39c3-talk/39c3-talk-spoken-text.md

It's a lot of text, but might be a good read and has more context to the history of the source code, the concepts, social/ethic questionability of DRM in mobility aids, etc.
