vopono VS RIOT

Vopono (https://github.com/jamesmcm/vopono):

"vopono is a tool to run applications through VPN tunnels via temporary network namespaces. This allows you to run only a handful of applications through different VPNs simultaneously, whilst keeping your main connection as normal.

vopono includes built-in killswitches for both Wireguard and OpenVPN."

I think for now on Linux you (still!) have to use external application to do the splitting. Such is vopono

I use vopono to manage it for me with Mullvad though.

you might want to check out vopono, i've gotten it working with firefox and its nice

I highly recommend using something like vopono with this on Linux that runs only the target application (e.g. Transmission) in a network namespace in the VPN and only forwards the specified ports and only allows traffic via the VPN.

This is why I use vopono - you can run just the torrent client in the VPN on its own and the killswitch keeps it safe.

You can find the option in the settings of windows and android apps. Unfortunately, it's Still not available for Linux. As a workaround for Linux, you can use vopono, which has OpenVPN support for Proton. Or just manually add routing table entries :)

I wrote vopono, I use it all the time for quickly spinning up browsers through different VPNs for checking geographical restrictions, etc.

RIOT-OS is somewhat popular in academia, it tries to be very approachable but there are still plenty of low hanging fruits with all kinds of hardware and you can use it for software and thesis projects.

Just one example: https://github.com/RIOT-OS/RIOT

You could also take a look at RIOT-OS. http://riot-os.org

RIOT-OS has a lot of unit tests for all the boards they support. And it's written in C. https://github.com/RIOT-OS/RIOT/tree/master/tests

Another option is using RIOT-OS. But that unfortunately doesn't support PWM for the Weact. It does support PWM for the Bluepill and Blackpill STM32f103 and the Nucleo-f446 After quick search. \ https://riot-os.org

If you want to use C, I would suggest trying out RIOT-OS. It's a modern embedded operating system, written in C and focussed on IOT. It works on a lot of different boards. https://github.com/RIOT-OS/RIOT

Alternatively, you can also write your code in an RTOS. They often have scripts that make flashing and debugging easy. One that I personally like, and also supports Arduino, is RIOT-OS.
