  • COSS Community 🌏: "@kenrickcai" [Link](

  • Joseph Jacks (JJ) 🇺🇦: "On a long enough timescale, everyone will be a startup founder. On a long enough timescale, every company will start as an open source project." Link

  • GitHub: "When @liyasthomas created Hoppscotch, he built it from a developer's point of view: there's no gateway, firewall, landing page, or friction for developers of all levels to get started.

  • Emad: ""Queen". #RIP #AIArt #StableDiffusion

  • Emad: "Open source AI is the way Congrats to @amasad and the @Replit team. Amazing things to come as we help the next billion code.

  • Ryan Florence: "If you want your OSS project to gain traction there's really only one thing you need to do: Document it well. - 10m quick start - Realistic examples that can be copy/paste/tweaked - Contextualized code samples for every API - Guides to put APIs together into a real use case" Link

  • Glenn Solomon: "Excellent interview by @alex of @HashiCorp CEO @davidmcj on why open source startups have PLG as a natural growth model: "our goal with open source is actually to drive standardization for users --- we think it's good for everybody." via @techcrunchLink

  • Joseph Jacks (JJ) 🇺🇦: ".@StableDiffusion is to images what PageRank was to web pages. That's the best way IMO to understand how profound the @StabilityAI mission is.

  • Joseph Jacks (JJ) 🇺🇦: "We need "Nutrition Facts" for software. Our bodies are fundamentally affected by what we put in them. The same is true with our brains and the software we consume. Open source can unlock this. What is the digital equivalent of a calorie ... carb ... sugar?

  • Joseph Jacks (JJ) 🇺🇦: "Given the rate of improvement vastly outpacing humans, ALL software founders must now factor in the implications of @StabilityAI's #StableDiffusion and implement changes in development accordingly. Those who don't will become quickly irrelevant, much faster than most realize." Link
