And/or a lot of misconceptions. I showed up many times as well with those links, and explanations and whatnot.

I recommend https://blog.adacore.com/, too. Ada/SPARK is great when you want formal verification, and your checks to be done by GNATprove; statically, instead of dynamically. FWIW, you can disable runtime checks in Ada.

I also commented https://docs.adacore.com/live/wave/spark2014/html/spark2014_... not too long ago. The whole documentation is useful anyway. You can prove the absence of memory leaks, among a lot of other stuff!
