    I'd absolutely love to play with this. one idea I had is to train another model to create bitmaps of sidewalks and roads and add a simulation for pedestrians and cars. day/night cy…

    switch to auto mode and it should still work!

    Here's an interesting negative result. After watching this video, my first thought was whether recent results from columnar compression (e.g. https://docs.vortex.dev/references#id1…

    I really love this space: Navarro's book is an excellent survey. Erik Demaine has a few great lectures on succinct data structures too: L17 and L18 on https://courses.csail.mit.edu…

    can you specify the algorithm in more detail? this looks to be solving a different problem than A*, which operates over discrete graphs. this looks to be operating in 2D continuous…

    this is unbelievably cool. ~27ns overhead for searching for a u32 in a 4GB set in memory is unreal. it's interesting that the wins for batching start diminishing at 8. I'm curious …

    I love playing with it at UltraHigh quality and 1 solver iterations. It reminds me of gradually incorporating one ingredient into another when cooking: like incorporating flour int…

    +1. I'd be curious how much of a pessimization to uncontended workloads it'd be to just use `tokio::sync::RwLock`. and, if we want to keep it as a spinlock, I'm curious how much th…

    looking forward to it! I'd be curious if y'all end up supporting adding filter attributes to the inverted index that can then be pushed down into the posting list traversal. for ex…

    very cool stuff! I just read the SPFresh paper a few days ago and was wondering if it's been implemented in industry (e.g. Turbopuffer's implementation of SPANN). I'd be curious ho…

    note that convex is open source! https://github.com/get-convex/convex-backend if you don't want to manage your own infrastructure, you can use our hosted product, but otherwise it'…

    yeah! we were talking to the antithesis folks during this project, but it wasn't far enough along when we started the project in 2016. we were heavily influenced by the original fo…

    adding to the chorus here - this is great tech. we use it internally at convex for implementing OLTP full text search. other than its runtime characteristics, the codebase is well …

    this is a really cool idea. one followup I was thinking of is whether this can generalize to queries other than key value point lookups. if I'm understanding correctly, the article…

    super cool stuff — such deep OS integration is refreshing when we mostly just see cross-platform electron apps these days.

    the post calls out replication and durability, and I'd be curious to know more there too. do they replicate within a fly region? S3 replicates to multiple AZs within an AWS region …
