I spend so much time repairing and improving my old #recumbent #bicycle from 1999 I bought on Blocket that I'm thinking of just designing a new bike from scratch. But then I realise I know almost nothing about solid mechanics and there are a lot of important details, like how much pedalling power the frame absorbs by bending: http://www.recumbents.com/wisil/brown/bicycleframedesign.htm

How to come up with good technical names, like the Unscented Transform, by Jeffrey Uhlmann:
"Initially I only referred to it as the “new filter.” Needing a more specific name, people in my lab began referring to it as the “Uhlmann filter,” which obviously isn’t a name that I could use, so I had to come up with an official term. One evening everyone else in the lab was at the Royal Opera House, and as I was working I noticed someone’s deodorant on a desk. The word “unscented” caught my eye as the perfect technical term."

Une proposition concrète pour l'Europe : et si on commençait à enseigner sérieusement l'#espéranto ?
Jen pripensinda propono pri Eŭropo: kio pri oni serioze komencu instrui #Esperanton?
You could do
>>> m = scipy.sparse.lil_matrix(n, n)
and then assign values one by one like
>>> m[i, j] = v
but this is still kinda slow.
It's better to do:
>>> rows = [...] # list/array of row indices
>>> cols = [...] # list/array of column indices
>>> vals = [...] # list/array of values
>>> m = scipy.sparse.coo_matrix((vals, (rows, cols)), shape=(n, n))
#debugging is fun
Oh interesting, apparently #chitosan can be made from #fungi: https://www.sciencedirect.com/science/article/pii/B9780128179703000146
(but it's not widely available yet).

Thanks, #python, I hate it.
