The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

When your embedding provider is good, but could be better for your use-case.

Hey folks, Elias here. Excited to unveil my latest project. Why I Built This: Traditional keyword search isn't cutting it. I've used LLM-embeddings to provide more nuanced, relevant results. How It Works: LLM-embedding similarity on curated datasets for semantically similar results. No need to iterate over keywords any more. Current Datasets: - YC Companies - Show HN Posts, - Ask HN Posts - ProductHunt Startups - Github Top 200k Repos Use Cases: - Validate a product idea's existence - Check if someone already Asked HN something - Have fun - search random terms and see what pops up Want to…

Hey, guys and girls :) Please notice, that my intention is not to advertise my project here, but to ask for your advice. Long story short: we've noticed that it's very hard to "sum-up" any idea on one page and share it without using a blogging platform. Let's say you want to collect and present your point of view on "IA reaserch". You can write a blogpost or use social media to share your opinion (that would reach limited amount of people though). We really missed a tool that allows you to embed a lot of different resources on one page and than to share it with one link. This way you can…

Would appreciate a star (and happy for ideas on improving indexing speed/embedding quality)!

Hi HN! I kept hearing about Lisp and why it was special but didn't have a great place to start. I wanted something self-contained that helped me develop intuition rather than fluency. My hope is this is helpful for casual programmers, professionals from other fields who interact with code, or engineers who haven't had much exposure to interpreters or compilers. Hope this helps anyone else who's curious about getting a sense of Lisp and what makes it special with a limited time investment! Feedback or other cool Lisp things welcome :)

Dear HN Community, I am a long time fan and first-time contributor. I just launched a developer focused semantic search platform and wanted to share it with the community. The idea is simple: upload structured or unstructured documents, select the fields you want to index and tag as metadata, and instantly get a clean search API you can use in your own app. Here is what it currently supports: - Manage your own tenants and projects - Upload .json and .txt files (support for .pdf, .docx, .xlsx, .yml, etc. coming soon) - Expose 3 APIs: search, upload document (embeddings), and delete document -…

I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

AI search results are quickly becoming more important than SEO, but as businesses, we have no visibility over it! That's why I'm building "Ahrefs for AI search results". Track keyword performance on AI tools like ChatGPT, Claude, Perplexity & more

Hey everyone! I am excited to share updates on four of my & my teams' open-source projects that take large-scale search systems to the next level: USearch, UForm, UCall, and StringZilla. These projects are designed to work seamlessly together, end-to-end—covering everything from indexing and AI to storage and networking. And yeah, they're optimized for x86 AVX2/512 and Arm NEON/SVE hardware. USearch [1]: Think of it as Meta FAISS on steroids. It's now quicker, supports clustering of any granularity, and offers multi-index lookups. Plus, it's got more native bindings than probably…

TLDR: I'm building an experimental open source/open data thing to collect good lecture recordings website: https://lectures.koljasam.com/ repo: github.com/koljapluemer/awesome-lectures Hi everyone, this submission is my attempt to contribute something to the question of how we will find, share and evaluate information in the future, in the face of the many problems that I think HN is well-aware of (slob, search engines returning SEO garbage or corporate stuff, spam, trust problems, big companies eating everything,...). I was specifically inspired by recent…
