A mere .01% equity seems fair

I'm not a fulltime developer, but manage a large dev team now. So, this project is basically beyond my abilities to code myself by hand. Pre llm, I would expect in neighborhood of 1.5-2 months for a capable dev on my team to produce this and replicate all the features.

41 hours total of prompting, looking at code diffs, reverting, reprompting, and occasional direct code commits. I do review the full code changes nearly every step of the way and often iterate numerous times until I'm satisfied with the resulting code approach.

Here's mine fully deployed, https://hackernewsanalyzer.com/. I use it daily and have some users. ~99.7% LLM code. About 1 hour to first working prototype then another 40 hours to get it polished and complete to current state.

Show HN: Hacker News Analyzer – LLM summaries of the most active threads

sahn44 — Thu, 18 Sep 2025 00:45:06 +0000

I'm a long-time reader of HN comment threads as an unusually effective way to get a lot of wisdom quickly about a wide array of topics that interest me. I built this tool to make that process even more efficient. It pulls the top stories, filtered for the ones with the most comments, and then lets you run an analysis of the comment thread. When you click "Analyze", it fetches full text of the entire comment thread, uses LLM to summarize key points, areas of consensus/disagreement, sentiment, etc (you choose short/medium/detailed length), and, finally, suggests context-relevant follow-up questions you can trigger.

I've been using it daily on my commute for a few weeks now as another/different way of consuming HN.

I’d love feedback — both on the idea itself and the execution. No signup is required to try it out for free. I used Lovable to build it, which was a lot of fun and a bit addictive for a little while.

I taught English in Seoul for a year in '02/'03. bang = room. There was (maybe still is?) a PC bang on every block or two pretty much. I'm sure I went at least 100 times. Great way to kill some time playing counter-strike for me and dabbling in starcraft. It was maybe $1.50/hr at the time. For a much better PC, nice chair, pre-installed games and snacks available.

This article bummed me out. I think this analogy of popular digital content being the 'junk food' of the brain is correct and the negative effects will, yet again, accrue disproportionately to the poor and less privileged in society. Sadly, it looks inevitable with no mechanism to prevent or counter it.

Great resource and very well written articles. I'm always curious how these come to be when done really well. I wish we could generate high quality, useful, correct, internal documentation like this at my company, but I've never figured out how to get that done in practice. The people that know the concepts are not natural/gifted writers, or at least wouldn't be motivated or prioritize doing this. Even if they did, the style/tone/depth would vary greatly. For these msft docs, they somehow achieve consistent tone, depth, and quality/correctness across so many domains and I just don't know how that's achieved.

sahn44 — Sat, 04 Feb 2017 14:01:26 +0000

Totally right. I've been building a skill and you quickly learn how un-magical Alexa is. Most of the effort is engineering in fine detail to achieve some degree of natural interaction for your users. For example, adding in state and awareness of what the user said before to influence the skill's behavior and response. It feels like I'm inventing all that from scratch rather than the alexa platform helping achieve that.
