Streamline Workflow with CEOS: Claude Meets EOS

I’ve been aware of EOS (Entrepreneurial Operating System) for over a decade. A number of companies I’m on the board of use some element, or all of it. Several friends, including Bart Lorang , are EOS Implementers. Last night, while watching Olympic highlights and the first few episodes of Steal , I created a v0.1 of CEOS — an open-source project that brings the core EOS toolkit to any Claude Code session. I went from an empty GitHub repo to a public-ready project in about 90 minutes. Please feel free to make fun of Amy and me about how we spend our Friday nights. ...

The Re-Rise of Open Source

Kevin Kelleher’s article on GigaOm this morning titled 2009: Year of the Hacker made me think back to the rise of open source after the Internet crash of 2001. In the aftermath of the crash, many experienced software developers were out of work for a period of time ranging from weeks to years. Some of them threw themselves into open source projects and, in some cases, created their next job with the expertise they developed around a particular open source project. ...
