DRM schemes

The top 10? Bottom 10? In any case, enjoy a breakdown of 10 digital rights management schemes. Also, admire Amos' restraint as a YouTuber that they waited until 2025 to make a numbered list. Visit sdr-podcast.com/drm-schemes to see the show notes and transcript! This episode is sponsored by Depot: the build acceleration platform that's on a mission to make all builds near instant. If you're tired of watching your builds in GitHub Actions crawl like the modern-day equivalent of paint drying, give Depot's GitHub Actions runners a try. They’re up to 10x faster, with unlimited concurrency, faster caching, support for Linux, macOS, and Windows, and they plug right into other Depot optimizations like accelerated container image builds and remote caching for Bazel, Turborepo, Gradle, and more. Depot was built by developers who were tired of wasting time waiting on builds instead of shipping. It's made for teams that want to move faster and stay focused on what actually matters. That’s why companies like PostHog use Depot to cut build times from over 3 hours to just 3 minutes, saving tens of thousands of build hours every week. Start your free 7-day trial at depot.dev and let them know we sent you.
