Monty - Python in Rust for AI(opens in new tab)
When LLMs write code to accomplish a task, that code has to actually run somewhere. And right now, the options aren't great. Spin up a sandboxed container and you're paying a full second of cold start overhead plus the complexity ...

Case Statement: Building a Harness(opens in new tab)
I codified my job as a DX engineer into a system that dispatches agents, enforces conventions mechanically, and learns from its own failures. Here's how case works and why I think every developer should build something like it.

Exactly Why and How AI Will Replace Knowledge Work(opens in new tab)
https://youtu.be/g3SrYIUv-OE There's a common narrative right now that you don't need to worry about AI if you're a knowledge worker. Humans are special. Humans are unique in the way they approach work. AI is just a text generator—just an LLM ...
Securing Production Debugging in Kubernetes(opens in new tab)
During production debugging, the fastest route is often broad access such as cluster-admin (a ClusterRole that grants administrator-level access), shared bastions/jump boxes, or long-lived SSH keys. It works in the moment, but it comes with two common problems: auditing becomes ...

Claude sure goes down a lot for being a product targeting businesses. Maybe Anthropic is just doing humanity a solid by helping us understand how much it will suck when the era of subsidized pricing for LLM-based products ends.

🔥 We blew past this milestone without much…(opens in new tab)
We blew past this milestone without much fanfare, but it bears repeating: building awareness & goodwill by releasing open source no longer makes strategic sense for many companies. Agents increasingly consume & adapt OSS—often without users' knowledge—and cut out the ...
The Invisible Rewrite: Modernizing the Kubernetes Image Promoter(opens in new tab)
Every container image you pull from registry.k8s.io got there through kpromo, the Kubernetes image promoter. It copies images from staging registries to production, signs them with cosign, replicates signatures across more than 20 regional mirrors, and generates SLSA provenance attestations. ...

🔗 Models are commodities, harnesses are differentiators(opens in new tab)
Ben Thompson's latest rests on a single load-bearing assumption: that the harness and the model are tightly coupled, the way Apple's hardware and software are. It follows, then, that if agents require integration between model and harness, that the companies ...

Pro-tip to any devs who only discovered TDD thanks to coding agents: refactoring is inherently directional. It's more like prefactoring—you rearrange code to make the next change easy. That means you (and your agent) should know the next planned change ...
