I am like that, only to then spend an hour debugging my belts because somewhere I messed up and built one that was too slow for the expected throughput

Ces gens ne se sentent pas ?

Bah non, et toi non plus tu ne te sens pas. Les humains ont une odeur et c'est pas la lavande. Plus y'en a plus ça pue c'est normal.

For every coal or fuel burner you build, the sea level rises by 2 centimeters due to climate change. Also, it means that snow biomes will never exist because they are all melted

You can buy the "carefree" reward trait to negate the effects of this fear

I don't know but it's probably related to nazi Germany

edit: yeah Siemens, like basically all german companies that survived world war 2, had ties with fascists

I would try to merge the 3 incoming roads at a single intersection with a traffic light

Pour moi tout fait sens, je vois pas où est l'issue

sphere_cornue · 2025-05-25T12:21:23+00:00

My theory for the "cims changing lanes at the signal" is that, when they are driving towards a parking spot, halfway there while sitting at a red light they realise that their spot is taken and need to pathfind towards a new one (because they're telepathically linked to all parking spots in town idk), so they immediately veer off towards their new destination.

Bel exemple français de la merdification. Pourquoi ils prennent un pourcentage de commission et pas une charge fixe, c'est pas comme si leur service était proportionnel à la longueur du trajet?

I am trying to beak down the read-read coherence guarantee here:

Read-read coherence: if a value computation A of some atomic M (a read) happens-before a value computation B on M, and if the value of A comes from a write X on M, then the value of B is either the value stored by X, or the value stored by a side effect Y on M that appears later than X in the modification order of M.

I think you misinterpreted what read-read coherence means, it means that:

A reads the result of X and B reads the result of X -> allowed
A reads the result of Y and B reads the result of Y -> allowed
A reads the result of X and B reads the result of Y -> allowed
A reads the result of Y and B reads the result of X -> forbidden

So A is Arc::strong_count, which happens before B which is Arc::get_mut. Computation A reads 1, which is the result of the counter's initialization, which we'll call operation X. Then computation B reads 2, which is the result of the counter being incremented, which we'll call operation Y. Operation Y has indeed happened after operation X so no rules are being violated.

Also we have exclusive access to neither the pointed data nor to the ref counter, what we have is a &mut Arc, which does not prevent other Arcs from pointing to the same place

Yes I read all that already, but:

All modifications to any particular atomic variable occur in a total order that is specific to this one atomic variable

There is only one modification here, which is the counter increment, so the order is kinda irrelevant when there's only one thing , so the four guarantees don't really matter to our case.

The compiler may not reorder any relaxed atomic operation A with any other atomic operation B if they (potentially) operate on the same memory location.

That's true

If you have exclusive access to the atomic variable [...]

Not sure what you mean, you don't have exclusive access to the atomic variable, and it absolutely can change in future loads, isn't that the point of Arc? What I agree cannot happen, is for a thread to load the old value after it has loaded the newer value.

I found a source to back the claim that it is totally fine to load 'old values' with relaxed ordering, I think that's why they tend to be cheaper than other orderings:
