Improving C# Memory Safety
The `unsafe` keyword is being redesigned to mark caller-facing contracts rather than just syntax. Safety obligations between callers and callees become visible and reviewable. The model is motivated by the rise of AI-assisted code generation and arrives as a preview in .NET 11.

sp.h: Fixing C by giving it a high quality, ultra portable standard library
Over the past year, I’ve been working on fixing C by giving it a high quality, ultra portable standard library. It is not a simple wrapper on top of libc; it doesn’t depend on libc except when required to by the platform. To my knowledge, there is nothing like it.

The quadratic sandwich
If you have ever tried to minimize a function with gradient descent, you probably noticed that some functions are a joy to optimize and others are a nightmare. The difference often boils down to two properties: strong convexity and L-smoothness. These two concepts define a “sandwich” of quadratic bounds around your…

Learnings from 100K lines of Rust with AI (2025)
In the past few months, I’ve been stress-testing how far AI coding agents can take us when building real, production-grade distributed systems. The result: a Rust-based multi-Paxos consensus engine that not only implements all the features of Azure’s Replicated State Library (RSL) [1] — which underpins most major…

Using HTTP/2 Cleartext for a server in Go 1.24
I'll give a brief outline of how to enable HTTP/2 cleartext (h2c) in a Go API server when you are using Go 1.24 or newer. This is useful in Cloud Run environments, which handles TLS termination but can take advantage of HTTP/2 features.

The occasional ECONNRESET
Two services running on the same machine. One of them opens a listening TCP socket bound to localhost, the other one connects to that. They exchange data. Every now and then , the service that initiated the connection gets an ECONNRESET while reading data from the socket -- but no other errors show up in the logs, no…

Hosting a website on an 8-bit microcontroller
My victim is the AVR64DD32 which is quite similar to the Atmega328 of Arduino fame. Compared to the older Atmega, these AVR DD lines are cheaper for the same memory, use a single programming pin and have nicer peripherals:

The Fil-C Optimized Calling Convention
Fil-C achieves memory safety even for programs that behave adversarially. That includes casting function pointers to the wrong signature and then calling them, exporting a function with one signature in one module and then importing it with a different signature in another, or even exporting a symbol as a function in…
