Ask HN: Why are so many "AI evangelists" posting such insufferable content?

My LinkedIn feed is absolutely unreal right now. 90% (I don't even think I'm exaggerating) of the posts in my feed are from connections who have changed their title to something like "AI Thought Leader | AI Native | Thought Coaching". They post *daily* about something LLM/agentic. The biggest problem is that it's never "hey check out this cool thing", it's "if you're not doing this, you're a dinosaur who will be left in the past." Other common content is regurgitating blog / Twitter folks from "

Show HN: ctx – Search the coding agent history already on your machine

Coding agents don't have long-term memory. But you do have months of full-fidelity agent transcripts stored on your machine. A simple solution that goes a long way: ingest those transcripts and logs into a structured SQLite database, then search them with ranked text match. Everything is fully local and doesn't require anything fancy like a graph database or hosted memory service. This is the idea behind ctx, a Rust CLI that handles the ingestion and searching. We give our agents a skill that te

Show HN: zkGolf, competitive optimization of formally verified circuits.

Zero-Knowledge Proofs (ZKPs) let an untrusted proved show that computation was executed correctly without revealing the inputs to the verifier. However to prove anything, the computation first has to be expressed as a circuit: a system of polynomial equations (constraints) over a finite field. Circuits are the assembly language of zk and every constraint costs prover (and sometimes verifier) time, so production circuits are aggressively hand-optimized. Over the last months, we have been experime
