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.

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…

The M×N problem of tool calling and open-source models
Tool calling with closed-source models is seamless. You pass a list of functions to the API, the model calls them, you get structured JSON back.

Building a real-time AI tutor for 5-year-olds
We set out to build the first AI tutor to teach math and reading to kids ages 4-9. For AI to actually teach a five-year-old, pedagogy must be baked into the engineering. A child can't wait for a slow reply, can't read a chat interface, and can't unhear anything a model gets wrong. We wanted to share some of the…

Clojure: Transducers
Transducers are composable algorithmic transformations. They are independent from the context of their input and output sources and specify only the essence of the transformation in terms of an individual element. Because transducers are decoupled from input or output sources, they can be used in many different…
