FP vs OO talk

Here's a quite balanced talk about FP and OO that fits my view of the two paradigms. Give it a shot if you have 40mins on your commute or something.

TIL: paste -sd+

Following lectures, I found a neat trick I didn't know in the data wrangling chapter:

seq 100 | paste -sd+ | bc -l     # 5050

That's pretty nice.  I already had this usecase solved by an "addup" perl script that I stole years ago from Mark Jason Dominus' utils repo.

As a bonus, it reminds me the very similar trick to generate a regex that matches either of many words. That's part of my git pre-commit hook

Not exactly the same, but it also belongs to "Higher Order Shell"
