aditoon Feynman's Lost Lecture (ft. 3Blue1Brown) [video]

His later video where in the outro he mentions about going sponsor-free is the one that made me tear up

https://www.youtube.com/watch?v=rB83DpBJQsE&feature=youtu.be...

Here's a little bit of quote from the video:

=====

So... typically this is the part where there might be some kind of sponsor message. But one thing I want to do with the channel moving ahead is to stop doing sponsored content, and instead make things just about the direct relationship with the audience.

I mean that not only in the sense of the funding model, with direct support through Patreon, but also in the sense that I think these videos can better accomplish their goal if each one feels like it's just about you and me sharing in a love of math, with no other motive, especially in the cases where viewers are students.

=====

He's really a good person. I'm glad that now he is able to do this full-time by just the support from his patreon.

aditoon Show HN: Owl, a new kind of parser generator

It's often I stumble upon discussion mentioning the term LL and LR and other stuff related to parsing[0]. Without a proper CS background, it's quite hard to follow along. That first link[1] and the wikipedia page[2] mentioned there are really great. Many thanks for posting those. It really shed some light about those terms.

aditoon A proof-of-concept of a vulnerability in custom shell prompt scripts

> If the shell would expand the contents of PS1 when drawing the prompt, a raw ref name must not be included in PS1. This protects the user from arbitrary code execution via specially crafted ref names. For example, a ref named 'refs/heads/$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)' might cause the shell to execute 'sudo rm -rf /' when the prompt is drawn.
