Named after a noble gas coz google think they're better than you? Or, named for a gas that doesn't interact well because despite being announced you cannot use it?

For human readable, something that supports comments, probably toml. For machines, something fast. Probably not grpc tho coz bloat. For IPC, shmem.

Episode 41 – the age of the Universe, AI and literature reviews, and giant companions
Payel and Michelle delve into another group of wonderful papers on the astronomy arxiv! They discuss dating the Universe, comparing 2025 large language models in their ability to assist with literature views, telling apart exocomets and giant companions, early signatures of secular evolution in disk galaxies, and the abundance of data to come from Vera Rubin.

How interesting. Samsung dropped a paper a few days ago with little fanfare:

 KV-cache offload over a CXL memory pool.

 Really scrappy setup too. Early-gen CXL stack (2.0), old switches, yet simple interleaving of the KV Cache across CXL modules kept the GPUs as well fed as real DRAM!

Update: iddqd is now formally verified*! * with limitations that are fundamental to this kind of formal verification, making it a complement to the existing layers of validation For more, see: oxide.computer/blog/iddqd-u...
Update 2026-06-16: Since publication, we’ve used Soteria to verify that iddqd's no-duplicate-index invariant holds under arbitrarily adversarial Hash and Ord implementations. Soteria is similar to Kani in spirit, though with different internals that make it more compatible with iddqd. Soteria is implemented as a symbolic execution engine that lets you declare points of nondeterminism in your code. (For example, within iddqd, we represent an adversarial Hash or Ord return value as nondeterministic, since we want to model adversarially bad user code.) Then, it:

Compiles the Rust program into a form suitable for formal verification.
Interprets this form until it reaches a point of nondeterminism, treating each such point as a symbol rather than a concrete value.
Branches at each point where control flow depends on a symbol, validating that there is no UB and that the invariants specified by the program are upheld. A lot of the cleverness lies in how the possibility space is collapsed down to something manageable. For example, Soteria doesn’t have to enumerate every possible Hash value; rather, it only has to fork in places where control flow depends on the Hash value.

Measure circle w/ volunteers: 1. Center point, radius R 2. Place n volunteers on circle (evenly spaced) 3. Wrap rope around them → measure C 4. π ≈ C/(2R) 5. Add more volunteers → repeat from step 2 6. Stop when out of people.

Rust constants are slowly but surely getting more powerful! On stable you can parse constants from environment variables. I remember having to pull in weird crates & macros to be able to do this. #rustlang
const TASK_COUNT: usize = {
    let input = if let Some(string) = option_env!("PERFMON_TASK_COUNT") {
        string
    } else {
        "16"
    };
    match usize::from_str_radix(input, 10) {
        Ok(val @ 2..) => val,
        Ok(_) => panic!("PERFMON_TASK_COUNT must be 2 or higher"),
        Err(_e) => panic!("Could not parse `PERFMON_TASK_COUNT`"),
    }
};
