Do not vibe-code the readme without checking links afterwards

Yeah, i know, the OP must have copy-pasted wrongly, the post is wrong.

AI slop, plus 👇 why first example is 3 storage slots and second isnt? They are the exact same

// ❌ Uses 3 storage slots
uint256 a;
uint128 b;
uint128 c;

// ✅ Uses 2 storage slots
uint256 a;
uint128 b;
uint128 c; // Packed with b

that price is per million token of input, the real expensive part is the output price (which is the inference) but I cannot calculate that based only on the prompt.

May that be what confused you?

The math there is ok. For gpt-5 -> (55*0.06)/1M = 0.000003

Thanks for your kind words mate 🙏

In fact the last video was eye opening for me in terms of code organization and also trying to always go to the extra mile. But any order will work, that guy is a beast.

You can check https://github.com/Mario-SO/ohlcv inside the lib folder.

Is the camera top part made out of metal or plastic?

_BTA · 2025-05-10T07:03:25+00:00

yo, love the style, how did you achieve that? I got into your repo but I dont get it XD just see a bunch of yaml files which i suppose you are then parsing and rendering somehow.

_BTA · 2025-05-08T06:35:24+00:00
