Update (2023-06-28): Added “I required a file, but I want to know what files were actually loaded” I love puts debugging I am a puts debuggerer. I don’t say this to disparage people that use a Real Debugger. I think Real Debuggers are great, I’ve just never taken the time to learn one well. Every time I try to lean…

Data Still Dominates
I’m a huge proponent of designing your code around the data, rather than the other way around, and I think it’s one of the reasons git has been fairly successful… I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important…

Half of curl’s vulnerabilities are C mistakes
I spent a lot of time and effort digging up the numbers and facts for this post! Lots of people keep referring to the awesome summary put together by a friendly pseudonymous "Tim" which says that "53 out of 95" (55.7%) security flaws in curl could've been prevented if curl had been written in Rust. … Continue reading…
