#2Alumnus here, it’s Imperial College, London. It is a university (in its own right), but always goes by that name.

I knew that; I went to Kings! Apparently I haven't woken up properly this morning. Title changed.

it is not meant to look like that. The spacing/tabbing is all over the place.

#6Interesting tidbit for HN, Jobn Carmack helped a little with this project apparently https://twitter.com/ID_AA_Carmack/status/1254872368763277313

#7This code is great fun. Start here to explore the horror: https://github.com/mrc-ide/covid-sim/blob/master/src/CovidSi...
I like the way InitModel() crashes (I think) if a global pointer called bmh (short for bitmap header) isn't first initialized by calling InitBMHead() from Bitmap.cpp. I guess it's obvious to academics with giant brains that InitModel() depends on a bitmap existing.
But it gets worse - the pointer is declared in CovidSim.cpp but Bitmap.cpp reaches across the module boundary to initialize it. Sweet.
Edit: I feel bad now. It's great that this code was made public. I should be encouraging that. I think academics writing code for things like this should probably take an undergrad course on software engineering. I think the one that taught me about Abstract Data Types would be most beneficial the author(s) of this code.

'Academic code' is infamous for having that effect.

In my very limited experience, that's what a lot of code coming from academia looks like.

#10Some people have raised issues with the model[1][2], or rather, the software implementation of it.
There's also a (flagged) submission on HN discussing this[3] referencing [1].
