    Come join us, we have a fantastic team and lots of interesting challenges. In 2018 we shipped updates for a whopping 1,102 vulnerabilities, including some really tough ones like Spectre, Meltdown, and L1TF, all while keeping the kernel running.

    Reducing contention by local batching is one of the most effective things you can do. You typically don't actually need to put just 1 message on a bus, if you can queue up 1k messages on your local CPU and then put them all on the bus with a single shared update that's a HUGE win

    Not overstating: this is the best PL conference keynote I have ever heard. More than 10x. Maybe more than 100x. Every single person following me should watch this and get everyone following them to as well. No 2x playback. Stick with it. Listen. Hear it. No tech skills needed.

    I love this whole thread (read from the top). Three new up-and-coming programming languages (scopes, Zig, Odin) by three individuals. Some of them are playing with safety à la Rust. I'm optimistic for the future of programming (languages)!

    I've been a huge fan of Sacha Baron Cohen for a long time now, however, this has to be the most important thing he's ever said. This is the problem.

    It's been a year since I announced my Pledge of Conduct, based on 's Contributor Covenant. Honestly, I had hoped it would catch on. I think the Pledge is a strictly stronger statement than various project Codes of Conduct for the simple reason that it is personal.
