Microprocessors are messy 😵💫
Tried many abstractions to simplify, but I surrendered and embraced bare metal and embedded C.
Annoying to read a 300 page pdf datasheet in order to program a microprocessor, but it's better than leaky abstractions.

Is Mojo 🔥 Ready?
Documentation states 2 heavy dependencies:
* Pixi tool recommended
* Needs Ubuntu 22.04 LTS on Linux
I installed Mojo with uv tool, that worked on nightly build ✅
Compiled Conway's Game of Life on Fedora, it segfaulted, but worked after fixing Pygame bindings ☑️
Is that ready? 🤔

Mojo is the most promising new programming language.
It combines ideas from C++, CUDA, Python, Rust, and Zig. 🐍
Last year it was too alpha, but I took a second look. The Mojo tutorial example is Conway's Game of Life. I got it compiled and running in around 1 hour.
Impressive. ✨

Replacing burned out spark igniter, with glow plug, before next static engine test
Post mortem for a spark igniter, which malfunctioned when engine hit 1300 degrees celsius, during static engine test.

I wondered how the Isar Aerospace engineers felt about seeing their beautiful new Spectrum rocket crash after 30 seconds of flight.
A few of their guidance, navigation and control engineers stopped by on their way back from Andøya, Norway, and went out for beers.
They looked genuinely happy. 😃

Spectrum flew for 30 seconds. 😅
Nobody was surprised or judgemental about the crash.
Failure is part of the job.
One of the engineers argued that they should have failed earlier.

Watched the first launch of the Isar Aerospace Spectrum rocket with several rocket engineers.
They cheered at take off.
Isar Aerospace chief executive had said that he would be happy with a 30 seconds flight.

But pose-estimation app is quite complex, built in layers by Conan, CMake, Ninja and compiler.
Using Heavyweight libraries OpenCV and TensorFlow. See in dependency graph below 😱
Fine when the abstractions are not leaky, but I spent a lot of time troubleshooting the app due to a corrupted XCode

I got pose-estimation, Conan 2's computer vision example to build from same CI script on Mac and PC 🔨
cd examples/libraries/tensorflow-lite/pose-estimation
cp -r ../../../../test .
python ci_test_example.py
./pose-estimation
Never thought I would see easy C++ cross platform builds. 🤩

Slowed down by conflicting #microcontroller advice 😵💫
Use
* Arduino Mega with Atmel studio
* ESP32 with PlatformIO and RTOS
* Raspberry Pi Pico
* CMake and C++
I experimented and had luck with PlatformIO, RB Pico; Arduino Uno, Mega and Nano.
Finally I got my digital 🧑💻 foot in the analog door ⚡

Retooling again 🛠️
It was more fun than relearning CMake 🥱 or configuring Kubeflow on AWS 😱

Luckily I could clean up my sloppy welding with an angle grinder.
Hope my steel work 👷 does better than my acrylics 🧑🎨

Today I welded steel and it felt like when I started painting with acrylics. 🎨
Acrylics were supposed to be durable with smooth transitions and endless painting on top. To me they were hard to mix and dull.
At my 1st MIG welding, the steel melted and became sticky, boiling chewing gum at 1300° C.
