Computation Graphs and Graph Computation
Research has begun to reveal many algorithms can be expressed as matrix multiplication, suggesting an unrealized connection between linear algebra and computer science. I speculate graphs are the missing piece of the puzzle. Graphs are not only useful as cognitive aides, but are suitable data structures for a wide…

Types as axioms, or: playing god with static types
A common perspective is that types are restrictions . Static types restrict the set of values a variable may contain, capturing some subset of the space of “all possible values.” Under this worldview, a typechecker is sort of like an oracle, predicting which values will end up where when the program runs and making…

Three Types of Data
In my work I’ve developed a mental framework related to data modeling, which has helped greatly both when coming up with a model and when making decisions down the road about how to use that model. Here I will establish three different categories of data in software: Constants, State, and Cached Values. By “data” I…

The lack of namespaces on crates.io is a feature
Rust doesn’t have namespaces in its package management system. It’s often viewed as a bug. But it’s not a bug, it’s a feature! While there are negative aspects of a flat package registry, there are also real benefits. Stability, continuity, and unity (discourages forks and fragmented identity)…
