Stopping the system fans to heat up the system to shift clock phase by a few femtoseconds is one of the less hinged ideas I’ve seen come out of CERN lol.

@jaseg Which kind of implementations could this be used for?

[jaseg@chaos.social]

@John_Ligher I think if you can avoid it there are better ways to achieve the same result. AFAIU this was meant as a retrofit for boards that lacked the necessary circuitry to do this in a nicer way.

[john_ligher@urusai.social]

@jaseg I see. Thanks for explaining. ^^

[rigrig@akkoma.tubul.net]

@jaseg@chaos.social Wow, neat.

Obligatory xkcd:

[riley@toot.cat]

@jaseg Wat.

[mancube@pnw.zone]

@jaseg that's a slick idea

[helle@tacobelllabs.net]

@jaseg Proper madness from the devs at CERN. I always like it when there is a common goal and someone is like "let me try something ridiculous so it fits our budget." - Vi

@jaseg how very CERN lol

@jaseg i think lady heather is doing fan temperature control for timing stuff for a while.

[owiecc@en.osm.town]

@jaseg physicists will do anything to gain a few femtoseconds.

@f4grx @jaseg gotta make do! *unhinged hacks ensue*

[casandro@f-ckendehoelle.de]

@jaseg That's actually not to strange of an idea. Some types of tunable lasers are also tuned via temperature.
Also many years ago there was some paper about determining the location of a computer based on the drift of their clock. Essentially the idea was that room temperature changes with the sun and therefore you can find out of it's day or night. Based on that you can find out the location.

@jaseg This is really neat! What's the scale of the x axis?

[jaseg@chaos.social]

@davidr about half an hour I think. The original slides are linked down thread.

[tammeow@cute-spellcasting-ideas.eu]

@jaseg no, this makes sense 🫠

[ela@infosec.exchange]

@jaseg I am impressed.
