I love this so much! @lauriewired, I always tell people to look into assembly language a bit. Even with all the high level languages and attractions, there is something very profound and beautiful to seeing how the bits and bytes move. You're a constant inspiration for that.🙏🏿
There’s a famous Usenet story about a programmer (Mel) who refused higher level abstractions.
It was the late 1950s, and even in that era, Mel was…well today we’d call him a boomer.
Mel only wrote in raw hexadecimal. He didn’t approve of compilers, and refused to use optimizing assemblers.
"You never know where it's going to put things”, he said.
Everyone else in the company was moving on to FORTRAN, and they didn’t understand why Mel was so stubborn about using new tools. He *loved* self-modifying code.
“If a program can’t rewrite its own code”, he asked, “what good is it?”
Mel eventually left the company, and other engineers were tasked with understanding what was left.
Mel’s hand-optimized routines always beat the assemblers; but some of it looked absolutely bizarre.
One engineer took ~2 weeks to understand why there were loops with no exit condition…yet the program worked fine.
I won’t spoil all the details, you should really read it, it’s short. But it’s a fantastic piece on “what defines a real programmer?”…which is becoming increasingly relevant in this vibe-coded era.
I strive to understand computers as deeply as Mel! If we aren’t careful, we’re going to lose the “Mels” of this world to time.
That’s part of why I go so deep in my youtube videos. I hope that younger viewers are genuinely fascinated by the inner workings of our machines, instead of handing everything off to higher abstractions.

@777_oya Heart is heavy yet the body is tea! I know you are working towards your fitness goal which I commend. Remember that a lot of women literally pray for the body you have now.
When your heart is heavy, but you remember your gym has a hot tub, sauna, and private workout rooms you always have access to. A Godis is deserving of a luxurious, easeful life.

It’s interesting how everything they labeled as demonic has been the very catalyst for my elevation and liberation. So many of the ancient practices that are rooted in healing, reverence, and remembrance have been distorted into something to fear.
Pray that my eyes remain open.
