That’s a great blog post, lots of details, helpful animations, historical context, and an interspersing of war stories.

I was confused. The title is bad. “its” is ambiguous and usually refers to the first subject in this sentence structure.

Weird take. The author corresponded with Dunning and reproduced the classic graph using random data.

Railway has an overwhelming incentive to pin the blame on Google. This report doesn't answer why Google suspended Railway's account.

I'd wait for more details before adjudicating.

New comment by sa46 in "Zero-copy protobuf and ConnectRPC for Rust"

sa46 — Tue, 21 Apr 2026 05:15:28 +0000

Presumably, OP refers to the generated rust types which depend on the specific protobuf framework.

I had the same issue when looking to adopt ConnectRPC for Go, which uses a custom wrapper type to model requests.

It might interest you to know JS has real private fields, formally introduced in ES2022. [1]

A new Go protobuf parser [1] made the rounds here eight months ago [2] with a specialized VM that outperforms the default generated protobuf code by 3x.

About 15 years ago, our brigade conducted a training exercise to test overall readiness. The opposing force (OPFOR) figured out how to triangulate the brigade headquarters' position using Tinder.

Tinder provided 1-mile granularity, so OPFOR would roam around until they had enough points to locate the headquarters. Then, they'd artillery it out of existence. The brigade commander was most displeased—moving a brigade headquarters is not for the weak or fainthearted.

govulncheck analyzes symbol usage and only warns if your code reaches the affected symbol(s).

I’m not sure about cargo audit specifically, but most other security advisories are package scoped and will warn if your code transitively references the package, regardless of which symbols your code uses.

New comment by sa46 in "Prek: A better, faster, drop-in pre-commit replacement, engineered in Rust"

sa46 — Tue, 03 Feb 2026 19:45:35 +0000

The problem is that pre-commit hooks are much slower with a much higher false-positive rate than type checking.

Pre-commit checks should be opt-in with CI as the gate. It's useful to be able to commit code in a failing state.

Wouldn’t a mono space font provide more information since you can extrapolate the exact number of characters?

sa46 — Sun, 07 Dec 2025 18:45:15 +0000

Advisory locks aren’t all sunshine and rainbows. They can only be unlocked by the Postgres connection that acquired the lock. That means you need to track the connection, typically by dedicating a connection to the job that needs locking.

Here’s a good issue describing the tradeoffs between a lock table and advisory locks.

sa46 — Thu, 04 Dec 2025 19:09:17 +0000

That's quite a strong claim. I disagree. Military leadership, like business leadership, is imperfect. Both vary based on individuals, the operating environment, and culture.

Depends on the state and child age. California is on the stricter end of legally mandated ratios:

0-18 months: 1:3

18 months to 3 years: 1:4

3-5 years: 1:5

Weight loss in Ranger School is additionally “aided” by limiting students to 2 MREs per patrol day (2400 calories) to increase stress.

Anecdotally, I lost 26 lbs in Ranger School.

Why not use the standard-library adjacent semaphore package?

One problem with using a channel as a semaphore is you need to track if you've closed the channel when "releasing".
