So a buy order for $122000M, and a sell order for $600M is presented as bad news for OpenAI?

Use the term, never define the term, classic.

CTE stands for Common Table Expressions in SQL. They are temporary result sets defined within a single query using the WITH clause, acting like named subqueries to improve readability and structure.

My AGENTS.md is usually `be concise` — it saves on the input tokens as well, and leads by example.

New comment by vlaaad in "Backing up Spotify"

vlaaad — Sat, 20 Dec 2025 20:46:22 +0000

Unrelated, but I just can't stop myself from saying that I absolutely hate Spotify even though I'm a paying customer. Fuck you Spotify. You were supposed to be a convenient way to discover and listen to music. Now you are only convenient for listening to music, and absolutely terrible for any recommendations. This is sad really. Spotify had good recommendations. It's absolutely in a position where it can provide good recommendations — it has both a vast music library and a vast amount of data on user preferences. And it chooses to push procedural/ai-generated slop instead to earn more money. I thought that maybe buying $SPOT stock will make me more at peace with its greed, but it didn't work. Spotify fucking deserves to crash and burn because it sees paying customers as idiots who might not notice they are fed garbage. Fuck you Spotify, fuck you.

Does this person also identify performance issues by reading the code? This is completely impractical.

New comment by vlaaad in "Agent Client Protocol (ACP)"

vlaaad — Sat, 30 Aug 2025 19:07:46 +0000

I love this idea; I hope it gains traction. One thing that is not clear to me is file search vs unsaved files. It's common for agents to use, e.g., ripgrep to search the file system. But if the communication protocol includes read/write access to unsaved files, there is a desync in terms of accuracy.. rg can't search unsaved files.

Yes, though I also liked the overall point of the post. Spotify recommendations are shit, and any playlist made by Spotify is full of garbage. I guess Ek knows this and, perhaps unconsciously, sees himself as evil, doing what's legal no matter how bad it is, with his weapon investments...

The difference between 99% reliability and 100% reliability is huge in this case.

vlaaad — Mon, 18 Aug 2025 13:20:29 +0000

Not true, structured outputs enforce output formats with 100% reliability, e.g., https://platform.openai.com/docs/guides/structured-outputs says "Structured Outputs is a feature that ensures the model will always generate responses that adhere to your supplied JSON Schema, so you don't need to worry about the model omitting a required key, or hallucinating an invalid enum value"

New comment by vlaaad in "MCP tools with dependent types"

vlaaad — Mon, 18 Aug 2025 12:36:12 +0000

Sure, but the need for accuracy will only increase; there is a difference between suggesting an LLM to put a schema in its context before calling the tool vs forcing the LLM to use a structured output returned from a tool dynamically.

We already have 100% reliable structured outputs if we are making chatbots with LLM integrations directly; I don't want to lose this.

I was considering making an MCP SEP (specification enhancement proposal) — https://modelcontextprotocol.io/community/sep-guidelines, though I'm curious if other MCP tinkerers feel the issue exists, should be solved like that, etc. What do you think?
