New top story on Hacker News: (Ab)using general search algorithms on dynamic optimization problems (2023)

(Ab)using general search algorithms on dynamic optimization problems (2023)
10 by h45x1 | 3 comments on Hacker News.
I wrote this blog back in 2023 but since then I became a frequent lurker on HN and decided to repost the blog here. For me, writing it was about connecting the dots between dynamic optimization techniques I've studied as an economist and the more general search algorithms studied in CS.

New top story on Hacker News: Show HN: Hackyournews.com v2

Show HN: Hackyournews.com v2
10 by ukuina | 0 comments on Hacker News.
A year and a half after I published https://ift.tt/P7KoWVR , I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use the Batch API [2] to drive down costs even further. Enjoy. [1] https://ift.tt/wbEy3tV [2] https://ift.tt/13vAK68

Phind 2: AI search with visual answers and multi-step reasoning
18 by rushingcreek | 4 comments on Hacker News.
Hi HN! Michael here. We've spent the last 6 months rebuilding Phind. The new Phind goes beyond text to present answers visually with inline images, diagrams, cards, and other widgets to make answers more meaningful. Here are some examples: "explain photosynthesis" - https://www.youtube.com/watch?v=cTCpnyICukM#t=7 "how to cook the perfect steak" - https://www.youtube.com/watch?v=cTCpnyICukM#t=55 "quicksort in rust" - https://www.youtube.com/watch?v=cTCpnyICukM#t=105 We asked ourselves what types of answers we would ideally like and crafted a new UI and model series to help get us there. Phind is also now able to seek out information on its own. If it needs more information, it can do multiple rounds of additional searches to get you the most comprehensive answer it can. This blog post contains an overview of what we did as well as technical deep dives into how we built the new frontend and models. I'm super grateful for all of the feedback we've gotten from the HN community and can't wait to hear your thoughts!

New top story on Hacker News: Show HN: Sort lines semantically using llm-sort

Show HN: Sort lines semantically using llm-sort

This is a small plugin I made for Simon Willison's llm utility. You can do things like: cat names.txt | llm sort -q "Which one of these names is best for a pet seagull?" cat books.txt | llm sort -q "Which book is more related to basic vs. advanced CS topics?" I see a lot of potential marrying LLMs with classic UNIX interfaces.

New top story on Hacker News: Show HN: Heap Explorer

Show HN: Heap Explorer
7 by bkallus | 0 comments on Hacker News.
I wrote a little LD_PRELOAD library that makes it easy to inspect and interact with a running program's glibc heap. It's fun to pause processes, free a bunch of their allocations, then resume them. Most of the time, the processes continue as though nothing happened, but sometimes they do interesting things :)
