liqilin1567··on My trick for getting consistent classification from LLMs
I think your understanding is correct.

I actually built a project for tagging posts exactly the way you described.

liqilin1567··on Building a message queue with only two UNIX signals
Yeah, there are a lot of more elegant, simple and reliable ways to do that.

It would be better if there are some real-world performance tests and comparisons with other embedding-only search methods.
liqilin1567··on Doing well in your courses: Andrej's advice for success (2013)
> Study very intensely RIGHT before the test.

Yeah, I don't think this works because I think short-term memory is unreliable under pressure and our brain usually absorb things during sleep.

liqilin1567··on Hacker News – The Good Parts
Sorry for the self-promo :D, I'm building a project for analyzing comments. Might be helpful, even if it's not exactly what you described.
liqilin1567··on Ask HN: Build Your Own LLM?
There is a new repo of karpathy: https://github.com/karpathy/nanochat. It's a full-stack implementation of an LLM like ChatGPT in a single, clean, minimal, hackable, dependency-lite codebase.
liqilin1567··on Ask HN: What are you working on? (October 2025)
Working on a project: https://hpyhn.xyz. It's a website for analyzing posts and comments on HN. The idea started as a way to help me learn from discussions and filter out posts I don't interest in.
liqilin1567··on Play snake in the URL address bar
Very interesting. What inspired you to build this, I'd love to hear the story behind this.
liqilin1567··on I built and launched the first AirPods-Controlled Game
Very curious how you get the motion data from AirPods.I read the app description and noticed that no modification to AirPods is needed

Tried it's detection out on the playground as a 9B model it's pretty good.
liqilin1567··on Ask HN: Software jobs with high barriers of entry?
from my perspective some 'low level' job like compiler, os kernel, performance tuning may require rich experience.
liqilin1567··on Ask HN: What are you working on (September 2025)?
Working on a Saas project(https://hpyhn.xyz) help me to learn fast on HN. On this journey I've became a full-stack dev from a c++ back-end dev thanks for LLM making that happen. By the way the back-end of tech stack of this project is nodejs and python haha-_-'.
liqilin1567··on Launch HN: Webhound (YC S23) – Research agent that builds datasets from the web
Just curious to ask: Is it legal to crawl content from reddit or LinkedIn?
liqilin1567··on Everything that's wrong with Google Search in one image
Just tried on my own on google, I get the Midjourney official site on 1 result, followed by Wikipedia about Midjourney. I am not a midjourney user.
liqilin1567··on Python on the Edge: Fast, sandboxed, and powered by WebAssembly
I am so excited about python edge supported by wasm because I used python on cloudflare worker but there are so many limitations just simple pure python code supported.
liqilin1567··on Many hard LeetCode problems are easy constraint problems
You're right to point that out, thanks for keeping things honest. My intention was simply to offer a helpful TL;DR for a very long thread, as it's a feature of a project I'm working on (mentioned in my profile).

I'm trying to contribute value without being spammy. If this crosses a line for the community, I'm happy to listen and adjust.

liqilin1567··on Many hard LeetCode problems are easy constraint problems
Yes,that is better. From my own experience, LeetCode does indeed enhance one's logical thinking and coding skills. I believe this is the reason why FAG has always tested algorithm and data structure skills in interviews over the years.
