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…

Does C++ still deserve a bad rap?
Traditionally C++ has been seen by many (and you know who you are) as just plain bad: the code is unreadably verbose, error messages are und...

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)…

Computer science is not software engineering
Wow, college was such a waste of time ... when did you ever invert a binary tree outside of an interview? Honestly I never inverted a binary tree in college either ☹️

In CPython, types implemented in C are part of the type tree
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

PEP 638 – Syntactic Macros
This PEP adds support for syntactic macros to Python. A macro is a compile-time function that transforms a part of the program to allow functionality that cannot be expressed cleanly in normal library code.

A New Back End for Cranelift: Instruction Selection
This post is the first in a three-part series about my recent work on Cranelift as part of my day job at Mozilla. In this first post, I will set some context and describe the instruction selection problem. In particular, I'll talk about a revamp to the instruction selector and backend framework in general that we've…

Emacs Lisp Animations
Emacs , a programmer's text editor with roots in the 1970s, is a great tool for animation. In Fall, 2010 I taught a digital art class at NYU's interdisciplinary Steinhardt art school. Clearly, the thing to do was to teach how to make animations in Emacs by programming it in Lisp.

Shipping Const Generics in 2020
It’s hard to believe that its been more than 3 years since I opened RFC 2000 , which defined the const generics for Rust. At the same time, reading the RFC thread, there’s also been a huge amount of change in this area: for one thing, at the time the RFC was written, const fns weren’t stable, and consts weren’t even…
