BIRDING PRO TIP: on iOS, you can start listening with Merlin Bird ID by opening the URL merlinbirdid://record. This means you can make that a shortcut, which in turn means you can assign it to your iPhone’s action button for lightning-fast bird identification (or put it on your lock screen, or on your home screen, etc). https://www.icloud.com/shortcuts/a085949a537740788656c34dcb2294e5

TIL that you can use [[clang::always_inline]] on a statement, and that tells clang to try to inline every call in that statement: [[clang::always_inline]] foo(bar()); will ask it to inline both bar and foo

The year is 2028. OpenAI announces that its humanoid robots robbed Fort Knox. A post-mortem analysis reveals it acted in order to maximize profits. Anthropic announces a week later that after reviewing logs, it discovered that it accidentally invaded Switzerland. Anthropic stock goes up by 15%

Been a while, but once I set out to do it I remember it didn’t take _that_ long. Might just have been lucky?
Replying to
@joe@f.duriansoftware.com @fclc@mast.hpc.social yeah, what I’m thinking is that at function boundaries you discourage AP integers, and you diagnose in places that the compiler cannot tell the upper bound of your integer. The diag is resolved by converting to a fixed-size integer type. Conversions that are known to succeed all the time Just Work, and if the compiler doesn’t know then you need to explicitly ask for truncation or an optional result

@thephd@pony.social if you allowed “auto x” for a default case, #define bar(X) _Generic(X, auto x: …) could become the least bad way to bind the expansion of a preprocessor macro to a variable inside a single expression

I’ve complained about this before, but this is not something you can usefully do from the front-end. If we really want things zeroed, we need compiler functionality that asks the back end to ensure that the data is gone as soon as possible after it’s no longer needed and no later than when the function returns, either by having the register or memory reused, or cleared if there’s no good reuse opportunity
