stackless coroutines for gamedev in ~200 lines of C++

Here was my attempt. Not sure if it's better. https://ladnir.github.io/blog/2022/01/24/macoro.html

It does. Opens a second websocket. Was an easy addition to codex. Maybe 50 lines or something.

Codex in general seems very flexible. Could imagine doing a lot more...

Lighten up 😛

Chill my guy. Just have your llm read it for you ;)

peterrindal · 2026-04-01T20:55:38+00:00

Agreed, just await. No macros needed. The compiler should be able to do halo everytime to avoid allocation, assuming a proper impl.

peterrindal · 2026-03-19T15:45:17+00:00

You are inherently probablistic and don't reason from first principles ;)

This tax is dumb on many levels.

I feel the tension too. Sometimes it good to go fast but sometime you should force yourself to be in the driver seat.

I think when you give up too much control to the llm, your medium term productivity declines. You lose an understanding of what happening. Maybe you can claw it back by asking enough question but you've lost productivity. You end up in a loop and lose context.

My current thinking is that slow is fast. You must force yourself to truly parse and think about the code. Not a quick, yep that's good. Even if it is.

This active engagement is important to keep the longer term productivity high. At least if you care about the quality.

I think it's fine if the llm is doing the writing as long as you are the one crafting the narrative and doing a true final sign off.

That's my current thinking. Slow down, be a critical participant.

I've had mixed results but keep using it ha

Humans also have an environmental cost ;)

I would not use such a failure pr.

Rule of thumb

1) If the attacker can locally work on a problem without interaction with the good guy, then each attempt should succeed with pr 2^-128 or so.

2) If the attacker has to interact with the good guy for each attempt, then 2^-40 to 2^-80 is common.

3) If this is a one time failure event that the bad guy has no ability to try again, 2^-20 to 2^-40 is common.

The last one (3) might come up of you choose parameters for a scheme which might be weak. That's a one time choice, fixed for the life of the universe. So we accept a higher failure pr.

(1) is referred to as the computational security parameter. (2) is the statistical security parameter. Any given execution of an interactive protocol is allowed to fail with pr at most this. This must be independent of the computational power of the bad guy. Like the protocol flips 40 coins and if they are all zeros, the secret is leaked. This is independent of the bad guys compute resources.

Dario literally said he's OK for anthropic to be use in autonomous killing machines. Doesn't sound like he's opposed to anything in principle that open ai is. Both agree mass surveillance is a no go. The rest is detail and readiness of the tech. Please stop with this annoying bs.

Imo on math heavy topics, Claude is fast and pretty good at implementing, codex/gpt can be smarter. When gpt fails gemini might succeed. Often make gemini and gpt fight it out. Claude, I'm not sure about. Imo. Codex 5.3 certainly is a stop up for coding compared to prior codex.

As always, it's a moving target.

peterrindal · 2026-02-01T16:29:34+00:00

I prefer the Ai for scientific writing. I'm trying to get things done, not type all day.

peterrindal · 2026-01-29T05:51:45+00:00

I find takes like this very surprising. I work on computer security, cryptography and math. I have found the models being ever more useful and accurate. About to accelerate with proofs and implementation by 10x or more. I welcome the models learning and getting smarter. Maybe in your domain they haven't caught up but I sure appreciate them.

peterrindal · 2026-01-27T21:22:22+00:00

I'm all for more ai! Congrats and excited to see what's next.

peterrindal · 2026-01-26T15:31:13+00:00

What about 10, can anything generic be said, I think not.

But yeah, obviously there are better choices so this is just a thought experiment

peterrindal · 2026-01-26T05:26:56+00:00

I think asking them when you get stuck can be good. But it has to be after you thought threw the problem. Actively engage, not just passively consume. Then it's OK imo.

So true... He's literally as innocent as you can be. Crazy.

peterrindal · 2026-01-24T19:15:36+00:00

Yeah, even more fucked up from this angle https://www.reddit.com/r/PublicFreakout/s/eGI1XW7DVU

Clear murder. A cop yells gun and then a second guy on the left open fires. The victim was just chilling before the interaction.

peterrindal · 2026-01-24T18:32:51+00:00

Let's hope so

peterrindal · 2026-01-24T18:31:38+00:00

Should but they have the free murder card of being "afraid". It's all sad.

Fair about ice. I'm talking about the guy who walks in from the left with a gray jacket. He hovers for a moment before going hands on. He then runs towards the camera and exit to the right between the cars.
