"The open source code will be published on https://github.com/stm32-hotspot/ for the final version of the paper."
-> paper is not final. And IIUC ST will be releasing the code at some point.
I find this a bit disappointing. Why not publish it with the preprint. Now we have no way to establish the quality of the two solutions or whether it is even possible to improve one of the solutions. I wonder why the C variant could not implement a JSON parser without malloc and free, while the RUST variant could.
nope, I was meaning the TeX source for the paper
