I'd be curious to see a more thorough comparison to S2, which IMHO seems simpler (it's just quadtrees) and likely faster (it supports O(1) lookup vs. needing a hierarchical search).

This may be a reference to texture streaming. While I've never developed for consoles, I do know that texture streaming on desktop & mobile can be challenging. Being able to mmap a texture directly from ssd (as if it were RAM), wi

If you take a step back, Google's launch & deprecate cycle for new products actually kind-of makes sense. Internally, Google is not so different from an ecosystem of VC-funded startups. They try a lot of things. Some ideas work a

Ceres is great for sparse, structured non-linear-least-squares problems (that is, problems where levenberg-marquardt is applicable). I believe it was initially designed for bundle-adjustment problems arising from structure-from-motion appl

How is this #2 on Hacker News? There's literally nothing here about how to actually build a database (yet?) Instead, there's just a key-value store implemented on top of a javascript hashmap and a filesystem.

Seriously. S2 is just quadtrees over a cubemap, with a nice mapping from integers to cells. So, instead of using a quadtree (because it's "complicated"), they chose to make their own two-level tree requiring O(N) linear scan

That animated gif is ridiculously misleading. To someone who doesn't know what's going on, it would look like this can hallucinate Emma Watson's face out of a 5x5 px image. Instead, this is essentially a fancy 2x upsampling,

You could implement almost all of this with OFX direct-connect. Good luck finding a bank which supports this though.
