A loan is subdivided and sold in different allotments each year at a different interests rate, principal, and terms. You want to sell the entire debt at some point in the future. How do you calculate the price such that you don’t sell at a loss?

You can most certainly render “as fast possible”. You are probably using a CAMetal layer render target with a delegate that is vsync’d to device refresh. You have to roll your own delegate or render target instead. Apple has a sample project in the Metal framework on how to do this.

Not the argument I was making and I’m not disagreeing with you.

Yes of course. It’s trivially easy to say “procedurally generate a mesh of description of unique shape”. If you can put it into words, the LLM can do it. Do you have any examples of something it can’t do?

I can’t believe I’m writing this comment.

A month ago I was still talking like you. Then I said to an insisting colleague, “watch I’ll try to vibe code a game engine and show you the crap it produces.”

Granted, this wasn’t my first game engine so I knew exactly what to say, but I was completely floored. GPT Sol & Astra at max effort was flawless at nearly everything I threw at it. I’m talking fully ground up, zero dependencies, just the primitives and SIMD. Fully featured engine done in two weeks with deferred 2-stage render pipeline, shadow maps, mesh shaders, MSAA, post processing, collision, physics, the works.

I even intentionally skipped a few important optimizations and went back to refactor them in, thinking there’s no way it can do a wholesale rewrite of major systems, but it did it. I got dry mouth from all the jaw dropping. My prompts got shorter and more ambiguous, so it would ask me clarify. I audited every line of code, and it was good (after adding two skills.md). I gave up. I’m a reluctant believer.

It sucks, but sadly these things are really good. Don’t be last contrarian, there’s nothing to gain. You’re just lying to yourself

Ctrl+a to carriage return the cursor seems work universally everywhere on a Mac. It even works on Microsoft products, incredible coming from the company that poorly reinvents everything and completely disrespects the default behaviors.

I always find this curious, is readline implemented at the hardware level or something? There’s just no effing way that was a priority ticket on Microsoft Teams given all the obnoxious weirdness of their chat text field.

And bizarrely, ctrl+k, ctrl+w, and ctrl+e are more seldom. Maybe 50-50 chance for those. But trusty ctrl+a is always there.

Scroll down. Ping is preferred because timeout is buggy

Yes, the transmission too. Never buy a used connect from a person that used it in the trades.

Not really. Around 50% of attendees have graduate or doctorate degrees. It selects for people that are smart, curious, wealthy, and not risk-adverse. This is very obvious if you’ve ever been.

Similar experience with a game engine. While working on one isolated component, like the render pipeline, a portion of the backing sparse data buffers were effectively duplicated with a different ABI. It’s like it forgot how to query meshes and game state, then assumed the plumbing didn’t exist so it was all rebuilt from scratch.

It compiled and ran just fine. If you weren’t reviewing the code holistically or keeping tight book keeping of your allocations you would not have noticed. Every single commit in isolation looks perfect. Very eye-opening

No way. Was this is Canada? Specifically in the upper interior of BC, during ski season? Either we know each other, or drilling holes in gasoline tanks is way more widespread. I have never heard of another instance of this happening, ever.

We’re not allowed to understand it. Gotta hit your PR quota to keep your job. I wish I was joking.

I am absolutely certain that I read this same blog post on a 1990s geocities-style page, or nearly identical in content and prose. I know this because I even showed it to my high school Astronomy teacher, who found it equally fascinating for entirely different reasons: I gave him a peek inside the wacky rabbit hole of the World Wide Web and he wanted more of it.

Anyway, can some please validate my memory? I do not want to experience this Mandela effect alone.

The quant side of finance is stochastic calculus and chaos, that’s what they’re talking about. Mandelbrot himself published a pop-sci book about the new fractal math of the stock market
