RIP nuage icon :(

Hearing about how #systemd is using varlink (simple JSON IPC) at #allsystemsgo gave me actual hope for #linux usability awesomeness.

Talk answers what varlink is and the many many reasons it's better (vs DBUS). https://www.youtube.com/watch?v=emaVH2oWs2Y

"It's so useful that it's JSON, because for the first time if I strace a systemd system I can actually make sense of the IPC calls being done... and this alone is one of the killer features of varlink that you can understand your fucking system now-a-days."

Varlink Now!

@gruber @stroughtonsmith you walked into this one, John 😜
Linux 6.8 improves concurrent TCP performance by up to 40% just by reducing cache misses https://www.phoronix.com/news/Linux-6.8-Networking
Linux 6.8 Network Optimizations Can Boost TCP Performance For Many Concurrent Connections By ~40%

Unfortunately, this paper doesn’t take Sage into account. But Orca, another RL based CCA, seems to perform well too https://arxiv.org/pdf/2307.10054.pdf
Super cool paper where they use RL to learn from existing CCAs, good and bad ones. They argue that their CCA performs well relatively consistently, as compared to existing algos
