Cinimatic Titanic is also great, with a mix of the original mst3k cast doing studio and live shows. The live show of Alien Factor is hilarious! https://en.wikipedia.org/wiki/Cinema…

Automerge is an excellent library, with a great API, not just in Rust, but also Javascript and C. > All you need for the backend is key-value storage with range/prefix queries; Thi…

I caught covid for the first time in jan of 2024, the illness itself wasn't that bad for me, like a common cold, but the aftereffects lingered for months. Eventually my ability to …

There are open source projects moving toward this scale, the GraphBLAS for example uses an algebraic formulation over compressed sparse matrix representations for graphs that is de…

redis-automerge is a redis module that adds real-time collaboration to json-like documents using the automerge CRDT library.

An interesting approach to characterize graph topology, both locally and globally is to use a graphlet transform, there some interesting research happening around these types of to…

uuidv8 does not contain a timestamp or counter unless you put them in there, it only contains a version and variant field. It's a very broad format that lets you contain whatever b…

That still exposes the timestamp, and the shift just drops precision, so I'm not sure what you're going for here.

Because then you leak the timestamp. The idea is, present what looks like v4 random uuids externally, but they are stored internally with v7 which greatly improves locality and ind…

You're right, I did read the article before commenting, but I see your point that I didn't completely understand the intent.

Fair enough, showing my age with "impossible". But still true that dense growth is not linear but quadratic to the number of nodes.

It's an interesting exploration of ideas, but there are some issues with this article. Worth noting that it does describe it's approach as "simple and naive", so take my comments b…

Yep, for any decent sized graph, sparse is an absolute necessity, since a dense matrix will grow with the square of the node size, sparse matrices and sparse matrix multiplication …

For a powerful sparse adjacently matrix C library check out SuiteSparse GraphBLAS, there are binding for Python, Julia and Postgres. https://github.com/DrTimothyAldenDavis/GraphBLA…

Beautiful, a great intro to and reference to core concepts. Definitely keeping this one around for mental refresh!

Not sure why this is being downvoted, it's a thoughtful comment. I too see this crisis as an opportunity to push boundaries past current architectures. Sparse models for example sh…

There is also a C api wrapper, not sure the state of it wrt this latest release.

Author and CEO here, we're excited to get OneSparse off the ground and show off some high performance graph processing with Postgres. Feel free to ask any questions!

Usd nickles have smooth edges.

Mastering Forth is also an excellent book and gets deep into the subject with very clear writing and excellent diagrams. https://archive.org/details/mastering-forth-by-anderson-ani…

I'm not sure about A5, but I do know that HEALPix cell boundaries are not geodesics, whereas S2 cells are always bounded by four geodesics.

This is a simple tool I use to turn my Postgres regression tests into Markdown for publishing with mkdocs similar in spirit to Python doctests. I decided to package it up into a to…

While this is a good approach to implements state machines, the transition function is hardwired to one transition graph. Another approach is to generalize the state and transition…

Agreed, his videos on Tropical Algebra are also very good!
