It should be noted that no ethically-trained software engineer would ever consent to write a DestroyBaghdad procedure. Basic professional ethics would instead require him to write a DestroyCity procedure, to which Baghdad could be given as a parameter.

It’s hard to overstate the value of LLM support when coding for fun in an unfamiliar language. [...] This example is totally trivial in hindsight, but might have taken me a couple mins to figure out otherwise. This is a bigger deal than it seems! Papercuts add up fast and prevent flow. (A lot of being a senior engineer is just being proficient enough to avoid papercuts).

Find a level of abstraction that works for what you need to do. When you have trouble there, look beneath that abstraction. You won’t be seeing how things really work, you’ll be seeing a lower-level abstraction that could be helpful. Sometimes what you need will be an abstraction one level up. Is your Python loop too slow? Perhaps you need a C loop. Or perhaps you need numpy array operations.

You (probably) don’t need to learn C.
