Especially painful on steam deck. If you get it working, it adds a good minute to the launch time

I’ll write an explanation here, but I’ll try to answer all questions from the thread. Also quantum mechanics is complicated, so sorry for the long text.

Electron orbitals are weird and complicated, for hydrogen we can solve them analytically and depending on the quantum number of the energy levels we are looking at, they take the forms as in the picture on Wikipedia:

Now whatever energy levels and quantum numbers are, what we are seeing is the probability of the location of the outer most electron (ok hydrogen only has one).

To understand bonds, we don’t really need the picture of orbitals, but what’s important is understanding that electrons occupy shells. A certain number of atoms can fit into a shell and when it’s full, the electrons start a new shell. It gets complicated quickly with more electrons, however in the simpler case, a shell can fit 2n^2 electrons, where n is the shell number. So for n=1, a maximum of 2 electrons can fit, for n=2, a maximum of 8 electrons can fit.

Shells want to be filled, so that leads to two possible bond types. If an atom with a free electron comes close to an atom that has a free spot for an electron, the electron can hop over to the other atom, at which point we have an ionic bond (the atom that loses the electron loses one electric charge and is thus positively charged, the other atoms gains an electric charge and is then negatively charged, so they want to be together).

Another option is covalent bonding, where instead of an electron jumping to another atom, the atoms actually share the electron.

Now do orbitals overlap? I wouldn’t give that question a yes or no, because, at that level, we can’t really separate atoms anymore. When the atoms are far apart we can draw separate orbitals for both, but when they get together, new orbitals form that is the solution of the electronic configuration of the new molecule we just created. It’s more like the orbitals that we have get deformed into new orbitals.

I wanted to see for myself and it looks like the spectra of the sun and moon are fairly similar:

Moon: https://olino.org/blog/us/articles/2015/10/05/spectrum-of-moon-light/comment-page-1/

Sun: https://seos-project.eu/earthspectra/images/Solar-spectrum_th.png

Looks pretty similar I gotta say

That being said, the intensity is of course much lower of the light reflected from the moon.

It’s really useful for programming. It’s not always right but it has good approaches and you can ask it to write tedious parts of your code like long switch statements. Most of my programming problems were solved because I just explained the problem like Rubber Duck Debugging.

Denying entry for people in need can’t be the answer. Honestly, it’s unfair that we were lucky enough to be born into a stable country. It’s unfair that other people have to live under dictators looking only for their personal interest. It’s unfair that people have to live under the consequences of global power struggles and it’s also unfair that Western countries exploit other nations and then don’t lend assistance when everything turns to shit.

How can you justify sending away these people that are fleeing from warzones or due to global warming. They are losing family and their homes and yet, they spent their life worrying while we can go to restaurants, cafes, play in parks, go hiking, swimming or biking without ever having to worry.

Leaning into the immigration policy of the right cannot be the answer, there has to be another solution.

Just wanted to mention at this point that the quantum computers in this post are the so-called superconducting quantum computers. There are also other architectures like ion and neutral atom quantum computers which are basically steel tubes with viewports that contain a ultra high vacuum. Lasers are used to control the ions or atoms.

There’s also photon quantum computers, but they are even more different and not in a really advanced stage yet.

Well my landlord is some foreign company, they pay a local maintenance company which manages the apartment. Of course the costs come back to me as the renter. Now the landlord gets free money just because they had enough cash to buy the apartment in the first place. And when they are done printing money, they’ll just sell the apartment for more than they bought it before.

You got it pretty much on point. Shooting a laser at atoms is like shooting a machine gun at an indestructible target. If it moves towards you, you can slow it down. But preventing it from accelerating when the target is stationary is where quantum mechanics comes in. That is your explanation: The laser light only acts as a force when the light is resonant with the atom and the Doppler effect means that the resonance condition changes depending on the speed of the atoms.

Given that you probably are using pointers, and occasionally you are allocating memory, smart pointers handle deallocation for you. And yes, you can do it yourself but it is prone to errors and maybe sometimes you forget a case and memory doesn’t get deallocated and suddenly there is a leak in the program.

When you’re there, shared_ptr is used when you want to store the pointer in multiple locations, unique_ptr when you only want to have one instance of the pointer (you can move it around though).

Smart pointers are really really nice, I do recommend getting used to them (and all other features from c++11 forward).

As a computer science problem it ends at position = window center / 2 - object width / 2

Because everyone can spin up their own irc server. It’s not federated though.

There’s also IRC

It shows Cherenkov radiation of a nuclear underwater reactor (I think, I don’t know this exact picture)
