@jann Another use case is periodic polling. Yet another is dealing with latency constraints, for example, compute it the hard and accurate way, but if that takes too long, compute it more quickly and less accurately. Another involves needing to do things that are not permitted in a restrictive context (e.g., interrupt handler), though things like irq work are better on architectures providing this.
All that aside, yes, I have seen timeouts used in cases where investing a little more thought might have provided a better solution. Then again, the same is true of pretty much all other facilities provided by the Linux kernel. ;-)

Slides from this weekend's Oregon State University Beaver BarCamp. Unusual topic, but a request. Fun session, good interaction.

It is my honor to be designated as Godfather of the 2025 edition of Kernel Recipes. The conference organizers made it quite clear that they would like some focus on increasing the speaking skills of the presenters. This blog series is a first step in that direction: https://people.kernel.org/paulmck/kernel-recipes-2025

I tried my hand at the sport of curling yesterday. The instructor quickly noted my distinctive personal style comprising strong elements of brute force, awkwardness, and beginner's luck. ;-)

andyprice@mastodon.socialUndefined behaviour in a programming language spec is a good thing because it enables optimisations. Similarly, taking the windscreen wipers off your car is a good thing because it improves aerodynamics.

@jfbastien @miodvallat Why mess around? Crank it up one more to PDP-12, and enjoy those lovely 12-bit words!!! And 12-bit address space, while you are at it!

@ljs @monsieuricon Being as I come from the Pacific Northwest, when traveling I either get good weather or weather that I a used to. This would be the second option. ;-)

@monsieuricon The river-level gauge is 15cm above normal, but 75cm to go before flood stage. There are a few clogged storm drains. More rain on the way!
