Userspace Statically Defined Tracepoints is a cool concept. With root access, you can attach dtrace or bpftrace to your program and see what your program is up to at those tracepoints. Any other time, those tracepoints are literal NOP instructions.

Google is hosting a CBP app that uses facial recognition to identify immigrants, while removing apps that report the location of ICE officials because Google sees ICE as a vulnerable group. @evystadium.bsky.social has more.

One of the most interesting recent privacy developments is the deployment of big two-hop IP blinding VPNs by companies like Apple and Google. These systems are designed to ensure that even those companies can’t link web requests to IP addresses.

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.

In concept I’m a huge fan of porting infrastructural code to Rust/memory safe languages, but shipping broken code — especially code that causes silent data loss — doesn’t help that cause.

Last week I wrote a section on (non-IO) blocking and async Rust for the async book: rust-lang.github.io/async-book/p.... I talk about 'not blocking the thread', combining CPU-intensive work with async, etc.
