Running Mailman it will not run in 1GB of ram (the US$5 VPS) so I had to give it 2GB. 2GB? For a mail list server?
Had the same problem running motioneye. It will not run on a Raspberry PI Zero. It is advertised to run on a Zero (Apparently I could squeeze it on by doing some Python magic....)
What total crap is Python! What waste, what hubris, what technical failure!
I suspect the problem is actually Django - what hubris! NIH! lighttpd is running sweetly, with some rust templating in a acceptable fraction of the memory.
