I have released Dea/L0 2.0.0, a major update to the self-hosted foundation of the Dea systems programming language. This release makes many pointer failures deterministic, gives native compiler execution a stricter security boundary, and brings project-maintained editor tooling into the repository. It also fixes subtle ownership and analysis differences between the Python bootstrap compiler and...

Every piece of software is the incarnation of thousands, even millions, of choices. From the choice of programming language and the overall architecture down to the minutiae of the build scripts. Complex, interconnected parts; subtle, long-term decisions; consequential but often unplanned interactions: all arise from the work of the software designer, the programmer, the architect. As every p...

Updated 2026-07-21. I have released Dea/L0 1.1.0, a focused update to the self-hosted foundation of the Dea systems programming language. This release makes control-flow cleanup safer, lets the frontend recover from more source errors, and improves the portability of the Stage 2 compiler without expanding the command-line or standard-library surface. One spelling for the path forward The cano...

Updated 2026-07-21. I have released Dea/L0 v1.0.0, level zero of the Dea systems programming language. This release is a major milestone for Dea. It improves the language surface, the standard library, compiler parity, diagnostics, Stage 2 reliability, test infrastructure, documentation, release processes, and CI workflows. Dea/L0 is designed for writing compilers and low-level tools. It has ...

Updated 2026-05-22. Today I’m releasing v0.9.0 of Dea/L0, the first level of the Dea systems programming language. This is the first public release, and the compiler is self-hosted: it compiles itself. Dea/L0 is designed to be practical for writing compilers and other low-level tools. What is Dea? Dea is a systems programming language built through staged bootstrapping. The language grows in ...
