    Thanks for having us on the show! I enjoyed talking about AI vulnerability research, the pressure it creates for maintainers and the CNA, and ultimately what this means for the BEAM ecosystem going forward.

    Zero security experience. $10. One afternoon. Peter Ullrich fed Hex packages to Claude and found a crash vulnerability in decimal in 30 minutes. New BEAM There, Done That podcast on what this means for every library in the ecosystem. youtu.be/FulShj7jc0o

    Atom exhaustion is not just an old BEAM footgun. As of today, 35% of CVEs published by the EEF CNA fall under uncontrolled resource consumption, with atom exhaustion being one of the recurring causes. It’s well understood, documented, and preventable. erlef.org/blog/security/…

    Hi Elixir friends, After 3 years building Hologram full-time (transpiles pure Elixir to JS, bringing it to the browser), I'm at a crossroads. Working 60+ hr weeks balancing contracts & dev isn't sustainable. Where we are & how you can help: hologram.page/blog/seeking-s… Even

    I received a small donation mentioning ads.fund, which apparently created a token around my open-source project. I’m not sure what to make of it and would appreciate community input on whether it’s legitimate or something to distance from. github.com/maennchen/ZipS…
