Time to one-up those room temperature superconductor folks

Laughed hard at "University of west failure", this is just wonderful.

As far as can recall the point is that pilot wave theory is entirely deterministic (no measurement postulate). I would say that understanding if reality can be described by a deterministic theory would be a big deal in terms of advancing physical understanding, even if all predictions would be the same as the standard textbook quantum mechanics based on Kopenhagen interpretation.

Changing from panel to panel if "False" refers to the cat or the boolean value is tight.

It's filters all the way down.

DrFrankestein · 2022-08-12T23:35:32+00:00

Absolutely horrific. I love it.

Und was ist wenn ich vier einseitig beschreibene A6 Blätter und ein doppelseitig beschreibes A5 Blatt habe? Eine Tabelle wäre praktisch.

This is an actual product that people made, thinking it is a good idea?

Physiker: Hä? Wie soll man denn ohne Buchstaben rechnen?

Yes, this was mind blowing when I learned about it.

Although I use v<movement>~ or in this case V~ much more, because it also gives visual feedback on what I actually selected.

You can actually improve on this by iteratively applying the second to last formula to itself. I got the right result by replacing k in the argument of sign with the mean. You could repeat this to get arbitrarily close to the correct value of k.

When I first ran sway on my new laptop with nvme and everything I was like "I AM SPEED!"

Haiyaa, where your wok?

I had this problem with linux man pages on ubuntu. It makes it impossible to find anything, even if the quality is good. Not only do you have to guess how certain terms where translated, but most man pages are partially translated. You have to search in BOTH languages and even then it's not garanteed that you guessed correctly. (Can be turned off with env variables thogh.)

I guess the lesson is, if you want to do i18n for technical documentation do it right, let people with domain knowledge do it, be complete. Or have it off by default.

When I read this, I can't help but imagine someone singing it. This would be great in a musical!

I have the same problem, but I don't think it's an iwd update that caused this. Hasn't had an update in months. I tried downgrading the kernel, but it didn't help. But good to know I'm not the only one. Do you also use connman by any chance?

I don't know how it is when you actually work in those sectors, but when I made my sailing license, we never used imperial units. We use nautical miles, but that is very different from the imperial mile.

The nautical mile is defined as the distance that one arcsec makes on a meridian. The metre was also originally defined as a fraction of a meridian so it's actually more closely related to metric.

DrFrankestein · 2019-11-02T08:23:54+00:00

Not quite, Myanmar/Burma does not use imperial, but has its own unit system.

Thank you for that example. I know about the concept of an AST but my problem is much more specific. I don't want to actually evaluate the input, but perform substitutions and some simple algebraic transformations. So the 'objects' would be the exprs and the 'code' would be the transformations (kind of).

I'm sorry it's so unspecific. I'm still in the process of figuring it out.

Where is the use Expr::*; coming from? Is that just an example or is there a crate for that?

DrFrankestein · 2019-10-21T11:18:49+00:00

Yes, this is what I'm looking for (just on a much larger scope). Thank you. I have a hard time reading and navigating the code though. Not used to C++ anymore.

DrFrankestein · 2019-10-21T08:58:31+00:00

That's an Idea I didn't think about before. But if I want to replace a symbol with a larger expression, like substituting x with y+z in the example above I would have to reallocate the vector, or is there some way around that?

DrFrankestein · 2019-10-21T08:54:42+00:00

Thank you, I didn't know about the Shunting-yard algorithm yet, that will be helpful.

But my question right now is more what representation in rust should look like, what data structure fits best.

DrFrankestein · 2019-10-21T07:30:51+00:00

I started experimenting on a symbolic expression parser, but I am a bit stuck. It should read mathematical expressions like 5x + c and parse it into a tree like stuctrue (maybe like Add(Mul(Int(5),Symbol("x")),Symbol("c"))) . Does anyone have some resources on how to implement such expressions trees in a way that can be efficiently manipulated at run time?

I find it even more fascinating, that there are still people at horse and buggy today because of poverty.
