My Harness Used One Label for Three Different Failures.

14+ min ago   (1083+ words) Three fixtures, three separate calls into the same reducer. Here is the complete failure_reasons each one returned, unedited: These are minimal fixtures with no sandbox event and no tool response, so the first and last codes fire in all three and…...

Docker vs. Kubernetes: Which Should You Learn First?

26+ min ago   (640+ words) This question comes up constantly, and the honest answer is that it's not really a choice between two competing tools — it's a question of sequence. Docker and Kubernetes solve different, related problems, and one is a genuine prerequisite for the…...

Stop Eating Free Scope: The Change Log Habit That Saved My Freelance Hours

1+ hour, 5+ min ago   (175+ words) Scope creep rarely shows up as a formal change request. It shows up as a Slack ping at 4:47pm: "Quick one — can we also add X? Shouldn't take long." You know you should pause. You also know saying yes keeps the…...

Build in the VM, Think on the Mac GPU: Debian 13 on Apple container With a Local Gemma 4

1+ hour, 33+ min ago   (1539+ words) This article walks through building a Debian 13 machine under Apple's container CLI on an Apple silicon Mac, and then wiring that machine to a local LLM running on the Mac's own GPU. Getting there has two halves, and the first…...

Giving an AI Agent a Real Sandbox: Filesystem and Network Jail, in Java

1+ hour, 37+ min ago   (733+ words) Ask a coding agent to run a build, and you have just handed a language model the ability to cat ~/.ssh/id_rsa. Prompt-level instructions like "do not read sensitive files" are not a security boundary — they are a suggestion to a…...

The Workflow Ran With Four Personas Instead of Five and Looked Fine

1+ hour, 15+ min ago   (504+ words) I run Claude Code as five separate subagents with different permissions — architect, coder, reviewer, conflict resolver, UI designer. One of them stopped loading. The symptom has the shape of not working well. The cause was not being there. Five conditions…...

Cutting PR review time is really changing where review happens

2+ hour, 15+ min ago   (248+ words) Atlassian reports its Rovo Dev AI reviewer cut PR cycle time by up to 45% internally and 32% for customers (primary source, Jan 2026). That figure gets quoted as proof that AI review saves review time. Read what the reviewer is described as…...

Two "Codex CLI" models on the same benchmark: the harness hides the model

2+ hour, 15+ min ago   (260+ words) Specific Labs dropped Real-SWE, an enterprise-code SWE benchmark, and the leaderboard is a great study in why you should never read "Claude Code" or "Codex CLI" as a model name. Same harness, two different brains: Same vendor's CLI, same harness,…...

Giving a coding agent more time barely helps

2+ hour, 15+ min ago   (627+ words) Real-SWE ran frontier models against licensed, private enterprise codebases (billing, tax, multi-service work) and one number jumped out at me: rollout duration barely moves resolution. 71.4% of rollouts that finished in under 10 minutes FAILED. 73.4% of rollouts that ran 10 minutes or longer…...
