My CS course in algorithm analysis had us implement a large num library (good for exploring n log n vs n^2 etc with practical examples) to the point where we could do exponentiation mod and implement RSA. It was a neat series of exercises.
And on the mathematics track, I took a course in the cryptography. Interesting but not always easy to follow (the "why" of key sharing algorithms "n out of m secrets needed" work was hard for me,, as was ECC).

I've been a frequent traveler for about 15-20 years and I had avoided it so far, but for a meeting in Paris the options were limited. Not again, if I can.avoid it. :No:
@GossiTheDog If only the Chief Security Scientist and Advisory CISO at Delinea had had an opportunity to listen to that episode, maybe they would have been better off!

I just checked the forecast for Paris next week since I have a work visit. 7 degrees and light rain is technically warmer than Umeå, but not by that much. @MariaLiv
@nlovsund
Of course, most of my time will be spent in an auditorium, but I wouldn't have minded slightly better weather (like this weekend's +20 and sunny). @MariaLiv
If you see a long German or Swedish word, first of all, don't panic. It's more scared of you than you are of it. Secondly, take a closer look and you'll see it's actually just three normal words in a trenchcoat, huddling together to deter predators (French and English).
HT to @wdormann here - somebody has backdoored the open source project XZ which has downstream impacts.
For example, although OpenSSH doesn’t use XZ, Debian patch OpenSSH and introduced a dependency which translates as the XZ changes introducing a sshd authentication bypass backdoor it appears.
One dude bothered to investigate in his free time about why ssh was running slow, so it was caught fairly early - i.e. hopefully before distros started bundling it.

One could argue that your tax money should also be spent by GCHQ to happen to look into increased CPU usage after some weird lib update in all the places where they didn't plant anything.
