  • ImHex

    🔍 A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.

    Project mention: Spectrum Analyser, a Sinclair ZX Spectrum reverse engineering tool | news.ycombinator.com | 2024-02-08

    Just one note: Please use UI scaling; it's near impossible to read on a 150% 4k screen (much less on 100%). Unfortunately, young eyes don't last forever.

    The UI looks very much like ImHex (https://imhex.werwolv.net/) is this a coincidence, or is it the standard ImGui look and feel?

    I wish ImHex had a decompiler for Z80 as well, but this is much better.

  • annoy

    Approximate Nearest Neighbors in C++/Python optimized for memory usage and loading/saving to disk

    Project mention: Do we think about vector dbs wrong? | news.ycombinator.com | 2023-09-05

    The focus on the top 10 in vector search is a product of wanting to prove value over keyword search. Keyword search is going to miss some conceptual matches. You can try to work around that with tokenization and complex queries with all variations but it's not easy.

    Vector search isn't all that new a concept. For example, the annoy library (https://github.com/spotify/annoy) has been around since 2014. It was one of the first open source approximate nearest neighbor libraries. Recommendations have always been a good use case for vector similarity.

    Recommendations are a natural extension of search and transformers models made building the vectors for natural language possible. To prove the worth of vector search over keyword search, the focus was always on showing how the top N matches include results not possible with keyword search.

    In 2023, there has been a shift towards acknowledging keyword search also has value and that a combination of vector + keyword search (aka hybrid search) operates in the sweet spot. Once again this is validated through the same benchmarks which focus on the top 10.

    On top of all this, there is also the reality that the vector database space is very crowded and some want to use their performance benchmarks for marketing.
