Which code examples do we use?

uekerman commented 1 year ago

For the testing and the CI block of the summer school, we would need two example codes. One that we use twice in the lecture as demo what to do (add tests, add CI). One that the participants then us twice to work on themselves.

For the SSE lecture, we used Python codes for both:

In theory, we could just convert these to Julia. It would, however, be nice to use the same examples in more lectures and exercises, for example to showcase how Pluto works or similar. Opinions?

ha! I was thinking this morning to use our own definition of mean - to make it more fun we could define our own number-type, but maybe this is too nerdy ;)

The second example is a diffusion solver. I think we have to define whether they should come up with their implementation themselves (need a sweatspot in difficulty to allow for bugs) - or we provide a bit more complex example.

mean / max (+ optional own type?) -> boring? => tstat or something useful for bootstrap?
calculating a fractal (mandelbrot or similar) -> hard to develop good tests?
diffusion solver -> too complex (conceptually)?

just leaving this here for tomorrow, a new numerical type called FlipFlopFloat64
