Featuring:Saron Yitbarek – Twitter, GitHub, WebsiteAdam Stacoviak – Mastodon, Twitter, GitHub, LinkedIn, WebsiteShow Notes:The Altair 8800 is why we have computers in most homes today. It was initially designed for hobbyists. But a few visionaries saw massive potential in this strange little machine—and worked hard to make others see it too. What they created led to so much more than anyone could have ever imagined. Forrest Mims tells us how his co-founder, Ed Roberts, planned to save their struggling electronics company. His idea? A microcomputer made for hobbyists. That computer led to a fateful phone call from Bill Gates and Paul Allen. Dan Sokol and Lee Felsenstein recall the unveiling of the Altair 8800 at the Homebrew Computer Club, and how it sparked Steve Wozniak’s eureka moment for the Apple I. We then hear from John Markoff about an infamous software heist that set the stage for the debate about whether code should be proprietary. And finally, Limor Fried reflects on how this story continues to influence today’s open source hardware movement.

Matthew Hodgson (technical co-founder) joined us to talk about Matrix - an open source project and open standard for secure, decentralized, real-time communication. It’s open source, it’s decentralized, it’s end-to-end-encrypted, and it’s also self-sovereign. Matrix also provides a bridge feature to bridge existing platforms and communication silos into a global open matrix of communication. A recent big win for Matrix was Mozilla’s announcement of switching off its IRC network that it had been using for 22 years and now uses Matrix instead.
