Rust testing or verifying: Why not both?
Dijkstra famously dissed testing by saying “Program testing can be used to show the presence of bugs, but never to show their absence!” As if you should choose one over the other. I don’t see them as opposites but as complementary techniques that should both be used to improve the quality of your code.

You can't make C++ not ugly, but you can't not try (2010)

Doing a math assignment with the Lean theorem prover
Note: this post was written for Lean 3; the latest version, Lean 4, is a very different language. Turn back the clock to 2009: a confused physics major newly infatuated with math and computer science, I enrolled in MATH 273: Numbers and Proofs at the University of Calgary. This wasn’t my first encounter with…

Don't trust default timeouts
Modern applications don’t crash; they hang. One of the main reasons for it is the assumption that the network is reliable. It isn’t. When you make a network call without setting a timeout, you are telling your code that you are 100% confident that the call is going to succeed. Would you really take that bet? If you…
