The 8000th Busy Beaver number eludes ZF set theory (2016)
I’ve supervised a lot of great student projects in my nine years at MIT, but my inner nerdy teenager has never been as personally delighted by a project as it is right now. To…

RNA Memory Hypothesis
There’s an old theory that memory is actually encoded in part in RNA. The argument is pretty simple: there’s no obvious way for all that sensory data to be captured in synapses as long …

Clever vs. Insightful Code
“Don’t write clever code.” Why not? “Because it’s hard to understand.” People who say this think of clever code such as Duff’s Device: Duff's Device send(to, from, count) registershort*to, *from; registercount; { registern =(count +7) /8; switch(count %8) { case0: do{ *to =*from++; case7: *to =*from++; case6: *to…

Reality Check for Cloudflare Wasm Workers and Rust
With native Rust support announced for Cloudflare Workers, one may be eager to jump in head first. I know I wanted to. However, I tested out a few use cases and found it too limiting. Either the desired APIs weren’t available, code size was too large, or the program couldn’t run within resource constraints. I remain…

JSON with Commas and Comments
Summary: JWCC is a minimal extension to the widely used JSON file format with (1) optional commas after the final element of arrays and objects and (2) C/C++ style comments. These two features make it more suitable for human-editable configuration files, without adding so many features that it’s incompatible with…

Prions
Editor’s Note 4/4/21: A few weeks after this article was published, a mysterious prion disease was identified in New Brunswick, Canada. I do not have to say that viruses have dominated every level of public conversation for the past year. Ancient and odd but relatively easy to talk about,

How the Canadian Tech Scene Encourages Finite Gameplay
Toronto is not the next great startup scene. Neither is Waterloo, or Vancouver, or anywhere in Canada. I’m sorry that I have to write this. I really am. I want it to work. But the growing cho…

Reading code is a skill (2020)
I’m inspired to write this post because Someone Is Wrong On The Internet. Of course a more accurate statement would be “I disagree with some aspects of what someone on the internet said, even though they have an entirely valid point of view”. But that’s less catchy. I saw a Tweet I violently agreed with, so I…

There is no “us” in team
I’ve talked before about the non-team team dynamic that is “one person per task”. Where the management and engineers collude to push the organisation beyond a sustainable pace by making sure that at all times, each individual is kept busy and collaboration is minimised. I talked about the deleterious effect on…

Implementing a LLVM Micro C compiler in Haskell
In this series, we will explore how to write a compiler for a small subset of C to LLVM in Haskell. Our language, Micro C, is basically a small subset of real C. We'll have basic numeric types, a real bool type, pointers, and structs. At the end of the series, we'll have a beautiful executable, mcc (Micro C…

Is content moderation a dead end?
Can we get content moderation to work, or is it as much of a dead end as virus scanning? Do we need to change the whole model of social instead?

XTerm: It's Better Than You Thought
A couple months back I switched my terminal from xfce4-terminal to the venerable xterm. For some reason I always put xterm in the same bucket as xclock, xmessage, or any other prehistoric command starting with X that comes pre-installed on any graphical Linux distribution.
