I’ve been experimenting with different approaches to running code in a sandbox for several years now, but my latest attempt feels like it might finally have all of the characteristics …

Anthropic extends MCP with a UI framework
Anthropic is turning Claude into an app platform, with interactive widgets from Slack, Figma, Asana, and others.
Write-Only Code | Heavybit
AI may be accelerating software into a world of "write-only" code that forces a rethink of culture, processes, and tools. Heavybit’s Joseph Ruscio explains.
Serpentine software
I don’t usually write hot takes. But StrongDM’s Software Factory post is worth it, so here goes. Their post is elegant, short, and well-written, so I’m going to just go through a bunch of pull quotes. Compounding correctness long-horizon agentic coding workflows [now] compound correctness rather than error This is a big, empirical claim. I’m already convinced by my own experiences that agents, suitably scaffolded, can form a Brownian ratchet, such that pouring on more compute helps, on balance.
Forking is Cool, or: A Unix Shell in Zig, or: Dave Learns How to Fork - ratfactor
In this article, I make a real, working interactive shell written in Zig. Though essentially a toy, it demonstrates the incredible elegance of the fork() system call and is an example of what can be done with absolutely no runtime memory allocations.
