I hoped it was clear in the blog post: this is a very specific case where I only needed to convert coordinates to h3 index, with this specific goal this transpiled version outperform the cgo version.
The comment "probably due to Go runtime scaling on multiple cores" was me still seeing very close performance with GOMAXPROCS set to 1, but observing the process behaving differently than the pure C version.
The fact it was not thread safe has been discussed already on Reddit and is not relevant nor an issue when used in a batch scenario like this.
ccgo is awesome, but feel free to discuss something else ;)
qemu is capable of emulating an ARM cpu so yes but won't be able to emulate all the real hardware, especially the opengl ES gpu.
From a compilation perspective I believe using a cross compiler is way more efficient than emulating the whole system.
Agree, creating something nice is challenging, 3d printings may help but I haven't started it yet, waiting to evaluate different screens first.
I've decided not to dismount the car block but using a phone stand modified for my screen.
It's full of ugly cables, the challenging part was to route a cable from the rear of the car to the front :)
