I’d go further and say while testing is necessary, it is not sufficient. You have to understand the code and convince yourself that it is logically correct under all relevant circumstances, by reasoning over the code.

Testing only “proves” correctness for the specific state, environment, configuration, and inputs the code was tested with. In practice that only tests a tiny portion of possible circumstances, and omits all kinds of edge and non-edge cases.

I find myself not really trusting just tests, I really need to try the app/new function in multiple ways with the goal of breaking it. In that process I may not break it but I will notice something that might break, so I rewrite it better

unwraps are so very easy to use and they have bit me so many times because you can nearly never run into a problem and suddenly crashes from an unwrap that almost always was fine

it really can't be that difficult to have a llm reference a known factual reference before giving an answer. Its really good at figuring out what you want and what to say, not far off to check references

Can we "swim" through space? Collect particles from space, add energy, expell them backwards to generate a net thrust.

no particles needed, we already have ion drive, just need electricity
