C has occupied the domain of microcontrollers for decades. Yet, the Internet of Things (IoT) is coming. That could mean many billions of insecure devices exposed to the network. Any input parsing code will be routinely probed for weaknesses. Given how infrequently firmware updates for these devi...
Any input parsing code will be routinely probed for weaknesses. Given how infrequently firmware updates for these devices occur, it’s critical that these are as secure as possible from the outset. Rust can play an important role here by adding a layer of safety without imposing runtime costs...
For example, given this input: The foo the foo the defenestration the The program should print the following: the 4 foo 2 defenestration 1 I think this is a good interview question because it’s somewhat harder to solve than FizzBuzz, but it doesn’t suffer from the “invert a binary ...
