So many gems in here but this one about microservices is my favorite:

grug wonder why big brain take hardest problem, factoring system correctly, and introduce network call too

I'm convinced that some people don't know any other way to break down a system into smaller parts. To these people, if it's not exposed as a API call it's just some opaque blob of code that cannot be understood or reused.

I swear I'm not making this up; a guy at my current client needed to join two CSV files. A one off thing for some business request. He wrote a REST api in Java, where you get the merged csv after POSTing your inputs.

I must scream but I'm in a vacuum. Everyone is fine with this.

(Also it takes a few seconds to process a 500 line test file and runs for ten minutes on the real 20k line input.)

Was it joining on some columns or just concatenating the files?

I'm going to laugh pretty hard if it could just be done with: cat file1.csv file2.csv > combined.csv

You need to account for the headers, which many (most?) csv files I've encountered have.

So I guess something like this to skip the headers in the second file (this also assumes that headers don't have line breaks):

  cp file1.csv combined.csv && tail -n+2 file2.csv >> combined.csv
