Stealing from Biologists to Compile Haskell Faster
The trick that makes GHC’s ApplicativeDo optimization faster is structurally identical to how biologists predict RNA folding.

SQLite is all you need for durable workflows
DBOS recently argued that Postgres is all you need for durable execution: if you already trust your database, you do not need a separate orchestration tier. I a…

One year of Roto, a compiled scripting language for Rust
By Terts Diepraam Almost exactly one year ago, we announced Roto, a JIT-compiled embedded scripting language for Rust applications. A lot has happened since then that we'd like to tell you about! 💡Along with this post, we published Roto v0.11.0! You can check out the changelog

Let's compile Quake like it's 1997
The first batches of Quake executables, quake.exe and vquake.exe were programmed on HP 712-60 running NeXT and cross-compiled with DJGPP running on a DEC Alpha server 2100A. In June of 1996, having shipped their title but concerned with NeXT stagnation, id Software switched their development stack.

Nitpicking the shell history scene in 'Tron: Legacy'
In the 2010 film Tron: Legacy , there's a scene where the main character Sam Flynn sits down at a computer in his father’s study, and types some commands to try to figure out what Flynn senior had last been working on, before mysteriously disappearing.

Tracing HTTP Requests with Go's net/HTTP/httptrace
net/http/httptrace has been in the standard library since Go 1.7 and most Go developers I talk to have never used it. It exposes hooks for the points in an outgoing HTTP request that you usually cannot see from outside the transport: DNS resolution, connection acquisition, TLS handshake, the moment bytes go on the…

Only 17% of all 64-bit Integers are products of two 32-bit integers
In software programming, the product between two integers is often computed to a fixed number of bits with overflow. Consider 8-bit integers. If you multiply 127 by 127, you get back the number 1 as an 8-bit unsigned integer, with an overflow. The actual full product is 16129. To represent 16129, you typically use 16…

Rust (and Slint) on a Jailbroken Kindle
I recently jailbroke my 7th generation Kindle Paperwhite. While my motivation probably should have been "breaking free from Amazon's clammy and tightening grip", the truth is I wanted a way to use it as a clock on my nightstand. I found this project and figured I could just make some adjustments to the code. And that…

From Rust to Ruby
Who does things like that?!? Apparently: me. I have my own project, written in Rust. Not a big one, mind you, maybe approx. 30k lines of code in total. Rust is verbose so it’s not really that impressive. I’ve put it aside for some time and was toying with local inference, LLMs, writing agents and my attention was…

Raft Consensus with a Minority of Nodes
Raft is a consensus protocol for managing a replicated log across a cluster of nodes. Its key goals are: (1) maintain a consistent replicated log of state transitions, (2) tolerate node failures, and (3) ensure a single leader coordinates all changes while multiple followers replicate. Raft is designed to be…

A New Typst Template for Pandoc (2025)
Last summer I spent a lot of time with Typst (at that point v0.11) and Pandoc, working on a flexible and reusable workflow to typeset markdown-formatted articles to PDF. I designed a Pandoc template for Typst that would do nice things with layout and typography, and I posted about that here .

C extensions, portability, and alternative compilers
Anyone who's written C knows that full ISO C standard-adhering code is an impractical rarity. Most real world C code out there relies on non-standard behaviors and language extensions to varying extents, and a lot of this isn't for extra features, but just to work around bugs and gaps in different compilers and…

Jira Is Turing-Complete
Engineering folklore holds that Jira (Atlassian's project-tracking tool) is Turing-complete . Existing claims point vaguely at automation features without exhibiting a reduction. This article supplies a proof, with setup instructions and execution trace.

Migrating from Go to Rust
Out of all the migrations I help teams with, Go to Rust is a bit of an outlier. It’s not a question of “is Rust faster?” or “does Rust have types?”, Go already gets you most of the way there. The discussion is mostly about correctness guarantees, run…
