Creator of Claude Code at Anthropic.

• Projects have changed not only how I interact with Claude but how I code. I stopped managing sessions. I just send thoughts as they come, Claude splits them into threads, and the project remembers how I work. It's where I do a ton of my coding now. [screenshot: my actual prompts for claude code cli yesterday]
  Quoting@ClaudeDevsToday we're rolling out Projects in Claude Code on desktop and web. A project is one conversation with Claude. It splits the work into threads itself, runs them as parallel cloud sessions, passes context between them, and keeps going when you leave. In beta for select users.

• I've been scratching my head trying to think how to package assets for my #lispGameJam project, I really REALLY wanted to be able to inline assets as raw hex code, like I normally do for uxn projects, not have to read binary files, so I added a special form with square brackets that lets me to just that! This is the first sprite(a little arrow) I was able to store in my source code.
