Losing NFS locks and the SunOS SIGLOST signal (utoronto.ca)

Safety in an unsafe world (lwn.net)
Joshua Liebow-Feeser took to the stage at RustConf to describe the methodology that his team uses to encode arbitrary constraints in the Rust type system when working on the Fuchsia operating system (slides). The technique is not unknown to the Rust community, but Liebow-Feeser did a good job of both explaining the method and making a case for why it should be used more widely.

Why computers are ridiculous now (write.as)
There's nothing fundamental that most of us are doing on a computer in the year 2024 that requires 16GB of RAM or a brand new processor. Why has it become the new default? Why does your computer that runs fine today require a replacement to run Windows 11? There's not one answer but several.

Waiting for many things at once with io_uring (mazzo.li)
When doing systems programming we often need to wait for something to happen. Common examples might be waiting for some data to come through a socket or waiting on a lock. We also often want to wait on any of several conditions to become true. A web server might be handling many sockets at once, waiting for any number of them to become readable or writeable.
