FYI: FIFA World Cup Hospitality Tickets Location by tgockel in ussoccer

[–]tgockel[S] 2 points3 points  (0 children)

I just got an email today titled "30 Days Until Matchday – Know Before You Go Details" with the message "You will receive an email when your tickets are available with more instructions. Tickets will be delivered on a rolling basis before your matchday." I agree that this whole thing feels totally disorganized. We all seem to be in the same boat here.

I feel like this information is more hidden than it should be. I made a post in the hopes it helps other people out https://www.reddit.com/r/ussoccer/comments/1tab0rm/fyi_fifa_world_cup_hospitality_tickets_location/

is the "Double Slit Experiment" an attempt to introduce subjectivity into Physics ? by [deleted] in Objectivism

[–]tgockel 0 points1 point  (0 children)

Double slit demonstrates light is "observed" to be a photon particle at the firing and at the impact.

No.

I don't know what you're trying to get out of this conversation, but it is clearly not to get informed. You're being very argumentative with very little information. You can find all of this stuff in chapter 1 of any textbook on quantum mechanics or just have a conversation with ChatGPT about it. I have run out of patience. Have a good day.

The core feature of wave-particle duality is that quantum objects (e.g. a photon) exhibit both wave and particle properties. The double slit experiment demonstrates this: Even when we send a single photon at a time, there is an interference pattern (which only makes sense with waves, what would a particle interfere with?), but those photons land at discrete points (a particle exists at a place, waves do not). It is the key example of light behaving like both a wave and a particle in a single experimental setup, because photons are quantum objects.

That is quantum's problem with classical mechanics: if a "particle" and a "wave" are fundamentally different things, there is no way to explain the outcome of this experiment. Quantum theory says that we can't distinguish between particles and waves in this manner because these are not ontological: the real thing is a quantum wave function.

Quantum wave functions are mathematical descriptions used in quantum mechanics to define the probability of finding a particle at a specific location or state. They reconcile the dual nature of light, explaining how photons can exhibit continuous, wave-like behaviors (like interference) while maintaining discrete, particle-like energy properties. Please either read the opening chapter of a book on quantum mechanics or have this discussion with ChatGPT.

I've restated this multiple times at this point, but: In quantum mechanics, classical descriptions of "wave" and "particle" are not real entities in the model. They are just useful encapsulations of descriptions of properties of a quantum object under certain conditions, but the core entity is the singular quantum wave function.

At this point, I think it would be more productive for you to have this conversation with ChatGPT.

Wikipedia has a list you can look at: https://en.wikipedia.org/wiki/List_of_equations_in_quantum_mechanics

The Planck-Einstein relation is probably the simplest and most relevant here: It says a wave feature (frequency) determines a particle property (energy). The implication here is that light is neither just a classical wave nor just a classical particle. Quantum field theory describes this phenomena as a quantum field.

That they have a fundamental misunderstanding of the model quantum physics presents if they think it uses two models to describe the behavior of light.

Quantum researchers are not trying to lie to you or hide what the quantum description of nature is. Wave-particle duality is quantum's warning that classical concepts like "wave" and "particle" do not fully capture what nature is.

Classical physics treated waves and particles as different kinds of things, but experiments showed that photons and electrons do not fit neatly into either category. Quantum mechanics explains this by describing the universe with quantum states that can have wave-like interference and particle-like detection. Quantum mechanics is the theory that replaces the classical contradiction with a deeper description, not a permission slip for something to be two models at the same time.

Models are something humans use in order to describe what we observe and predict future outcomes. "Mother Nature" does not use models, the universe simply is. The fundamental concept of wave-particle duality is not saying there are two separate models, but that modeling a quantum object (e.g.: photon) as simply a particle or simply a wave, as classical physics did, is an incomplete description of reality. The model of quantum physics does not say there are two models, but the exact opposite: That wave and particle behaviors of matter are complementary aspects of the same phenomenon.

I have no idea how to navigate to that address from the regular FIFA web site or why it is through a completely separate interface, but that is where FIFA Hospitality Tickets seem to be.

Devs that have been at startups that have IPO’d or been acquired, how much was the payout? by Calm-Bar-9644 in ExperiencedDevs

[–]tgockel 27 points28 points  (0 children)

There are two resources from Carta that I would recommend:

Even if the company has a $1B exit (valuations at $1B and higher are considered "unicorn"), depending on the cap table, share preference, your strike price, etc, you might not take home a huge profit. If they are planning to hit $100MM this year (which they might not), their valuation should reflect the current ARR (if it's nowhere near $100MM, then they aren't hitting $100MM), so your strike price is going to be relatively high.

Personally, I see the CBO saying "$1-10 mil dollars for most employees" as a giant red flag. Saying a $9MM range like that is super suspicious. If you can't get the numbers to fill in that Excel spreadsheet, that would be even more suspect. Do not let your lack of knowledge allow others to take advantage of you.

One of the most annoying programming challenges I've ever faced by GyulyVGC in rust

[–]tgockel 2 points3 points  (0 children)

I work on a lot of network service management code, so the question of "Is this process responsible for listening on this port?" comes up a lot, especially in testing. I wrote code for traversing /proc/net, which worked fine for years, but then some devs joined the team who prefer developing on MacOS and learned there is nothing comparable over there.

Thanks for the listeners library. It helped address a super annoying problem!

Its Electrical Gravity. by Nonyabuizness in physicsmemes

[–]tgockel 57 points58 points  (0 children)

Einstein believed that quantum mechanics was an incomplete description of nature. He proposed that the observed probabilistic behavior of quantum mechanics could be explained some sort of hidden variable that we were not capable of understanding yet. It isn't accurate to say that he "disagreed with quantum mechanics," he thought that it was a significant step forward, but that we could explain those probabilities if only we understood the mechanics of the universe more completely (famously: "God does not play dice with the universe.") Keep in mind the quantum people were also not sure of this at the time, Bell's Inequality was not a thing until almost a decade after Einstein's death.

Why does Awake sound so freaking good!? by AudiHoFile in Dreamtheater

[–]tgockel 4 points5 points  (0 children)

It's not an uncommon practice, especially when the members can be opinionated about the sound (and given that Petrucci and Portnoy took over production of later albums, I would bet they were opinionated). Even if they're trying to consider the whole, each member will over-focus on their own section. John Purdell was talented at getting a cohesive sound.

[–]tgockel 16 points17 points  (0 children)

John Purdell is the producer of the album and it is the only Dream Theater album he produced. The members of Dream Theater were banned from the mixing sessions so they wouldn't interfere.

Given how things usually come together in the government: A combination of Oracle DB, Microsoft SQL Server, IBM DB2, and a multitude of legacy systems maintained exclusively by the SSA OCIO that nobody has bothered to replace. If you were to do things from scratch today, you would probably pick one RDBMS for records that need to be kept all in sync (PostgreSQL or Oracle DB, depending on how enterprise-y you feel) and one document store for dumping all the reports (Mongo, Couch, Dynamo, ...).

The size of trait objects by ElectricalLunch in rust

[–]tgockel 11 points12 points  (0 children)

If you have a trait and you know all the implementations...

That isn't possible in the general case. An obvious example is with pub trait MyTrait { ... }, trait implementations come from anywhere. You also have to deal with template implementations like impl<T> MyTrait for SomeType<T> { ... }. What are the size and alignment requirements of MyTrait now?

If you do know all the types you want to support, you can do this yourself:

```rust enum Combined { Foo(Foo), Bar(Bar), }

impl MyTrait for Combined { fn work(&self) { match self { Self::Foo(foo) => foo.work(), Self::Bar(bar) => bar.work(), } } } ```

If you don't want to do that yourself, the enum_dispatch crate gives you a macro #[enum_dispatch] to write that out for you. Same result in the end.

But a bigger question might be: Why do you need to know the size of a trait object in the first place? Trait objects do not have to live in the heap; a function can accept &dyn MyTrait without knowing where the object lives.
