Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

Notes by djb on using Fil-C (2025) I'm impressed with the level of compatibility of the new memory-safe C/C++ compiler Fil-C (filcc, fil++). Many libraries and applications that I've tried work under Fil-C without changes, and the exceptions haven't been hard to get working. I've accumulated miscellaneous notes on this page regarding usage of Fil-C. My selfish objective here is to protect various

What’s New in Emacs 31.1? Emacs 31.1 adds a slew of quality-of-life features.

PowerShell: the object-oriented shell you didn’t know you needed | Chris Warrick
PowerShell is an interactive shell and scripting language from Microsoft. It’s object-oriented — and that’s not just a buzzword, that’s a big difference to how the standard Unix shells work. And it is actually usable as an interactive shell. Getting Started PowerShell is so nice, Microsoft made it twice. Specifically, there concurrently exist two products named PowerShell: Windows PowerShell (5.1)

NixOS is a good server OS, except when it isn’t Ever since I built my first NixOS system (building a custom image to upload on DigitalOcean), I’ve been bothered by one thing: the default installation size is too large.

In April 2026, Canonical disclosed 44 CVEs in uutils, the Rust reimplementation of GNU coreutils that ships by default since 25.10.

What’s notable is that all of these bugs landed in a production Rust codebase, written by people who knew what they were

TanStack Start is one of the most exciting full-stack web development frameworks I’ve seen. I’ve written about it before. In essence, TanStack Start takes TanStack Router, a superb, strongly-typed client-side JavaScript framework, and adds server-side support. This serves two purposes: it gives you a place to execute server-side code, like database access; and it enables server-side rendering, or
