Multicast TV Distribution on My Home Network

https://www.apalrd.net/posts/2026/isp_mcast/1.png
Today I am taking a look at the weird world of multicast, where packets get delivered more than once, and we route using a backwards routing table. But, once you understand how it works, a whole world of content distribution possibilities open up to you! Inspired by an old video by @TallPaulTech, I’m using live TV distribution as an example of how multicast works, and how it can potentially ...

Memory Safety Absolutists

The author discusses the recent criticism of Rust's memory safety, suggesting it's disingenuous and based on fanaticism. They argue that Rust minimizes memory safety issues and that Fil-C, a new way to make C and C++ code memory safe, has trade-offs that make it unsuitable for all projects.
