C Strings and my slow descent to madness
I’ve been on a C kick recently as I learn the intricacies involved in low level programming. As a Data Scientist/Python Programmer I work with strings all the time. People say that handling strings in C range anywhere from tricky to downright awful. I was curious so I decided to see how deep the rabbit hole went.

Moving from Rust to C++
Note to readers: this is an April Fools post, intended to satirize bad arguments made against Rust. I have mixed feelings about it now, as I think people who understood the context appreciated the humor, but some people were confused.
