Runnable examples Let's create and run some minuscule bare metal hello world programs that run without an OS on: an x86 Lenovo Thinkpad T430 laptop with UEFI BIOS 1.16 firmware an ARM-based Raspberry Pi 3 We will also try them out on the QEMU emulator as much as possible, as that is safer and more convenient for development. The QEMU tests have been on an Ubuntu 18.04 host with the pre-packaged QE
I'm developing an API client where I need to encode a JSON payload on request and decode a JSON body from the response. I've read the source code from several libraries and from what I have seen, I have basically two possibilities for encoding and decoding a JSON string.
