Become a backend engineer. Its my favorite site

This is also the best way to support me is to support yourself becoming a better backend engineer.

Hey I am sponsored by Turso, an edge database. I think they are pretty neet. Give them a try for free and if you want you can get a decent amount off (the free tier is the best (better than planetscale or any other))

" if you're not ready to argue uselessly for hours over things that don't even matter then you're not ready to be a programmer " no truer words have ever been spoken

every single language in 15 min. nah, thanks. 43 min reaction from prime. Here we go.

APL is named "A Programming Language" because that was the title of the book that they later turned into an actual language. It was pure theory first.

We have so much RAM now that someone made Redis. We just don't have that dog in us anymore.

6:03 rather have the stability of a financial system depend on COBOL, than NPM community packages tbh.

That's why the lady (and it was invariably a lady) that converted your written code into punchcards (yes, that was a job), she would put a thick line in marker pen diagonally across the top edge of the cards. This made the tripping-and-spilling your cards annoying but not suicide-inducing. You "just" had to restore the line and your cards would be in order.

Circa time index 19:20. RE: Babbage. The problem is, the British government granted him £5, 000 (IIRC) for the Difference Engine which he did not complete. To put that into perspective, that was the cost of several front line warships at the time. Charles realized he could do better and switched to the Analytic Engine in mid stream. This did not make him popular. On top of that, his protégée, Ada Augusta, who was not taken seriously due to being a woman was pretty much the only person to understand the full potential of the Analytic Engine. Not even Babbage understood its full potential. Ada wrote what is today considered the first program for automatic computing machinery. It was a program for the Analytic Engine that would calculate Bernoulli numbers. The machine was never built. Ada tried to get funding by betting on horse races. This did not go well for her. It is a rather sad and tragic story. She was eventually buried, after dying at a rather young age, next to her father, Lord Byron. Yes, the poet.

They had punch card sorters that physically implemented a radix sort, one column at a time. You started with the least significant digit and worked up. The machine would spit out a separate stack for each digit. You’d just pile up the stacks, feed them back in and run for the next digit.

[disks]

You don't hand number the punch cards you draw a diagonal line down the side of your stack with a sharpie. You'll always be able to put them back in order then. I've never written programs that way but I know someone who did in an academic setting. He said they would trip each other on purpose so you had to be prepared.

Modern cobol runs on virtual state machines implemented on top of Java or GCC's cobol standard library or similar. The primary reason cobol is still used is it is auditor-friendly. Auditors cannot generally _write_ cobol, but they can read it with minimal assistance. It is nearly a perfect subset of English, so if you can read english you can understand cobol.

2023, Prime does OCaml
2024, Prime does Elm and Charm
2025.. Prime learns

I've told this before but the punch card sorting reminds me:

I worked as part of a physics experiment and had a real world opportunity for quicksort. Briefly: We built a particle detector with ~2000 cables that needed to be connected in a specific order before it was installed. The team responsible for connecting cables finished their job, so my job was to connect cables in the correct order to test equipment so as to confirm the equipment was functional.

Problem: the cable guys didn't keep the cables sorted. I walked into a room full of ~2000 randomly tangled cables and had one afternoon to test all of them. I first tried randomly finding cables in order, no good, it would take a couple of days minimum.

But then my computer programming experience came to mind: In place quicksort the cables. I finished the task on time and got the reward of not being kicked out of the lab.

I guess prime went oop on this one

[AlFasGD]

When I saw this video I immediately realized that this guy has barely done his research and felt the irresistible urge to make a video showing all that half-baked knowledge

[dsteel]

80 seconds in: oh, it's that kinda tech video

[adityarahalkar]

"Zig is the truest successor to C/C++ there has ever been " well said prime.

5:52 ... that's the Czech National Bank ... it's still exactly the same as in this picture, and I work there as a developer. Just about an hour ago, I walked along this wall in the photo when I finished work and was going home. :)

PS: I use VSCode :P
PPS: but also Fedora .. and Vim for commit messages if not -m .. redemption ( ͡° ͜ʖ ͡°)

[AlexandruVoda]

There was another trick to keeping punch cards ordered that worked great: drawing diagonal lines across the spine of the stack so you could instantly see if a card was in the wrong place. I imagine people learned this trick really quickly.

I like how he mentioned Lisp and just figured that covered every language with a the lisp-like syntax
