Congrats on being so consistent. I have huge respect for you and thank you for inspiring the audience to keep coding.

Loved this stream as a bioinformatician! If you want to look into the applications of distances between strings in bioinformatics I suggest in taking a look at phylogeny algorithms, super cool stuff

You try to install a Python library and get an NPM error, that sums up everything.

Great as always, all your stuff is so interesting! And btw, drawing the matrix made it so much easier to understand. Keep on doing that!

New camera? looks great!! cool idea for a python tool too...

The sharp corners of the thumbnail look really nice in light mode 😂

Damn bro is out here reinventing Smith-Waterman hahahha

great stream !

@TsodingDaily small help on 1:35:16 with accessing "program" from the subcommand function: you can just raise an exception/error and print nice mesage from main function.

So annoying when tsoding can't use python properly, ugh. Anyway, I like the streams a lot. They gave me a few interesting ideas

Isn't just copying file2 to file1 easier?

8:14 THE ABSOLUTE STATE OF OSS LOL THAT'S *R O U G H*

You should've implement two separate scripts, so you follow the mantra: a tool does one job and does it flawlessly. In addition you can chain those scripts in a pipeline if the `apply` script can read patch from `stdin`

It seems you are from Ukraine :) Olivec is quite similar to олівець in Ukrainian. Nevertheless, great content!
