Every ChatGPT message triggers a Cloudflare Turnstile program that runs silently in your browser. I decrypted 377 of these programs from network traffic and found something that goes beyond standard browser fingerprinting. The program checks 55 properties spanning three layers: your browser (GPU, screen, fonts), the Cloudflare network (your city, your IP, your region from edge headers), and the ChatGPT React application itself (__reactRouterContext, loaderData, clientBootstrap). Turnstile doesn
A complete guide to CLAUDE.md, custom commands, skills, agents, and permissions, and how to set them up properly.

Teams-first Multi-agent orchestration for Claude Code - Yeachan-Heo/oh-my-claudecode

Scheduled tasks let Claude re-run a prompt automatically on an interval. Use them to poll a deployment, babysit a PR, check back on a long-running build, or remind yourself to do something later in t
A channel is an MCP server that pushes events into your running Claude Code session, so Claude can react to things that happen while you’re not at the terminal. Channels can be two-way: Claude reads
Subagents are specialized AI assistants that handle specific types of tasks. Each subagent runs in its own context window with a custom system prompt, specific tool access, and independent permissions
Each Claude Code session begins with a fresh context window. Two mechanisms carry knowledge across sessions: CLAUDE.md files: instructions you write to give Claude persistent context Auto memory: note

Since I was about 9 I've been puzzled by the apparent contradiction between being made of matter that behaves in a predictable way, and the feeling that I could choose to do whatever I wanted. At the time I had a self-interested motive for exploring the question. At that age (like most succeeding ages) I was always in trouble with the authorities, and it seemed to me that there might possibly be some way to get out of trouble by arguing that I wasn't responsible for my actions. I gradually lost hope of that, but the puzzle remained: How do you reconcile being a machine made of matter with the feeling that you're free to choose what you do?
In the science fiction books I read as a kid, reading had often been replaced by some more efficient way of acquiring knowledge. Mysterious "tapes" would load it into one's brain like a program being loaded into a computer.

AI speeds up writing code, but accountability and review capacity still impose hard limits.
In my opinion, one of the best critiques of modern AI design comes from a 1992 talk by the researcher Mark Weiser where he ranted against “copilot” as a metaphor for AI.

A few months ago, users started reporting that Ghostty was consuming absurd amounts of memory, with one user reporting 37 GB after 10 days of uptime. Today, I'm happy to say the fix has been found and merged. This post is an overview of what caused the leak, a look at some of Ghostty's internals, and some brief descriptions of how we tracked it down.1

My experience adopting any meaningful tool is that I've necessarily gone through three phases: (1) a period of inefficiency (2) a period of adequacy, then finally (3) a period of workflow and life-altering discovery.
We've spent the past year watching coding agents fail in every conceivable way: ignoring instructions, executing dangerous commands un-prompted, and going in circles on the simplest of tasks. We've se
