I'm writing poker for my bot in discord. So far I'm presenting an incomplete version of the project, which is only a betting system. The development took a lot of time, so I decided to ask for help. Perhaps something in the project structure could be optimized. import sys, os; sys.path.insert(0...

I'm trying to debug a failing legacy process monitor that searches processes that are running. I determined it is being caused by some mysterious linux behavior. The process being ran is /opt/my/path/directoryname/daemonname but for some odd reason, it shows up with spaces, not /, around directo...

Deuteronomy 18:15 “The Lord your God will raise up for you a prophet like me from among you, from your brethren—him you shall heed— 16 just as you desired of the Lord your God at Horeb on the day of the assembly, when you said, ‘Let me not hear again the voice of the Lord my God, or see this grea...

Let $G$ be a topological group and $\mathcal{B}$ its Baire $\sigma$-algebra (i.e. the smallest $\sigma$-algebra for which all continuous functions $G\rightarrow\mathbb{R}$ are measurable). Consider the product map $\cdot :G\times G\rightarrow G$ given by $(g,h)\mapsto g \cdot h$. Question: Is the...

I'm using the EPSG:3857 projection in QGIS. And I use a raster relief layer and several vector layers. Is it possible to make the map not interrupt at 180 degrees, but continue?

I've always heard that the target of a shebang line (e.g. #!/bin/bash) must be a binary executable, not a script. And this is still true for many OSes (e.g. MacOS). But I was surprised to see that this is not true on Linux, where up to 4 levels of scripts can be used, where the fourth script re...

Why are venomous mammals and birds so rare in comparison to reptiles and fish? Metabolic reasons? Morphology? Selection pressures? Why are not all reptiles venomous but many are? Why are platypuses venomous? Is there a difference between venomous and poisonous?

The Question: My Workings: My Mathematica Output: I am attempting to solve this problem using KCL, can someone tell me what I am doing wrong? My mathematica code is not outputting anything. Thank you

I've made a simple rock paper scissors game using javascript. Any feedback appreciated. This is a first project I've done with almost no help let computerScore = 0; let humanScore = 0; function getComputerChoice() { let computerChoice = Math.floor((Math.random() * 100)/40); //generates a numbe...

It should be possible to rewrite a non-recursive CFG [1] as an acyclic NFA, since non-recursive CFGs represent finite languages (and thus regular a fortiori). Is there an explicit algorithm to rewrite an ε-free non-recursive grammar into an equivalent ε-free NFA? My instinct is to put the grammar...

Let $X$ be a singular, projective (complex) variety of dimension $n$ with at worst isolated singularities. We know that taking cup-product with the cohomology class of $X$ induces a morphism from the cohomology group to the Borel-Moore homology: $$ \cap [X]: H^{2p}(X) \to H_{2n-2p}^{\mathrm{BM}}(...

Setting: In this world (i.e. the one in which you’re reading a WBSE post), intelligent life turns out to be fairly common throughout the Universe, just it tends to blow itself up somehow before it can colonize a major section of the Universe and find other intelligence, since discovering FTL is e...

In Mapbox GL JS I might do something like: const canvas = document.createElement("canvas"); canvas.width = WIDTH; canvas.height = HEIGHT; map.addSource('canvas-source', { type: 'canvas', canvas: canvas, coordinates: [ [WEST, NORTH], [EAS...

In Ahlfors's complex analysis $$ R(z)=\frac{P(z)}{Q(z)} $$ given as the quotient of two polynomials. We assume, and this is essential, that $P(z)$ and $Q(z)$ have no common factors and hence no common zeros. $R(z)$ will be given the value $\infty$ at the zeros of $Q(z)$. It must therefore be con...

My raw data has values on some random times: const rawData = [ {hour: 3, value: 3} , {hour: 5, value: 9} , {hour: 10, value: 5} , ] as const I would like to fill all missing hours as having value 0: const processedData = [ { hour: 3, value: 3 }, { hour: 4, value: 0 }, { hour: 5, val...

In Dune, the first novel in Frank Herbert's cycle, the condition sine qua non for the Imperial Sardaukar to take part in the venture is that the Harkonnens provide plausible deniability to the Emperor. In the final package, two legions of Sardaukar would complement the Harkonnen forces, fighting ...

Non-Euclidean geometries are generally presented as models for the first four of Euclid's axioms, which do not satisfy the fifth axiom (parallel's postulate). Most texts present two models of non-Euclidean geometries: hyperbolic geometry and spherical geometry. These two models can be considered ...

Let's say for example the magic items are as follows: Torvald's Insecurity. Your size is increased by one for as long as you are attuned to this amulet and it is on your person. Smeek's Sleuthing Stone. Your size is decreased by one for as long as you are attuned to this stone and it is on you...

Im attempting to drop a sphere on a turbo compressor wheel and i want the sphere to "roll" down the fin it hits. instead, when it falls its like it hits an invisible box that's near the comp wheel and shaped differently.

In the US, 1st Amendment includes not only free speech, but also freedom of assembly. A civil rights attorney working for Harvard Law School posted the contrasting two-scene video below, showing apparently different attitudes towards public gatherings with political elements. https://twitter.com/...

Assume I have any triangle $\triangle ABC$. I know that given the lengths two sides of the triangle and angle between them, I can find the length of the third side. In other words, given values of $AB$, $AC$, and $\angle BAC$, I can find $BC$. What if instead of the angle, I know the length of $...

Find all matrices $A$ such that $$A=\displaystyle{\sqrt{\pmatrix{1 & 3 & -3 \\ 0 & 4 & 5 \\ 0 & 0 & 9}}} $$ This is a UC Berkeley qualifying exam question. Now I know one method to solve this. Let $$A=\pmatrix{a & b & c \\ d & e & f \\ g & h & i} $$ Now on squaring we'll get $9$ equations and c...

In his PhD thesis, Gaitsgory (in his "remark 6") makes the following claim: Consider two complexes of holonomic $D$-modules with regular singularities on a variety $X.$ Suppose that at each point, the complexes have the same Euler characteristic; then in fact the Euler characteristics of the hype...

Around 2005, I read in a "Best of the Year" anthology I think, a short piece (novella or shorter) in which Blondlot really did discover N-rays in the early 20th century - and the technological jump that this gave to France led to France dominating the world later in the century. I thought the ti...

Today, I saw on the news that the prosecution in the current lawfare case against former-President Trump brought in a tabloid publisher to testify that Trump paid him to not publish negative press about him. Does this have any legal bearing on the case, or is it just for (ironically) the negative...

A concept in conversations I've wanted to say but have struggled to figure out the best way is to convey that I have "procrastinated" some task or that I tend to procrastinate stuff. The issue is all the associated Japanese words seem not to be what I am looking for: ►回答を先延ばしにする　put off a reply u...

Sometimes Chess engines identify the best move as a move that’s mathematically the best but would be difficult for a novice/intermediate to pull off because it must be followed up by a specific, careful sequence of moves or else it’s not a good move. Are there any Chess AIs that can identify the ...

When writing \[\sum\], a larger summation sign is used than when writing \(\sum\). How does the \sum command find out which size to use? What does \sum expand to? I am guessing it is just a shorthand for another longer series of commands, is it not?

There's a common misconception that after seeing atomic bombs tested, Robert Oppenheimer quoted the following passage from a Hindu epic poem, the Bhagavad Gita: Now I am become Death, the destroyer of worlds. Does he ever say this in the movie?

I was reading a book by Amy Karofsky where she puts forward the case for necessitarianism: the idea that what happens is the only possible way that it could have happened. She talks about how very few philosophers consider this view since almost everyone takes contingency for granted, especially ...

How to compute the rational approximation of square root of a fraction, i.e. I'd like to find $ \frac{a}{b} \approx \sqrt{\frac{m}{n}}$, where $a$, $b$, $m$ and $n$ are integers. Ideally, the approximation should only use additions, subtractions and multiplications. Thanks.

I was watching a debate here where the idealist says that on a physicalist perspective, consciousness is a brute fact. But if one posits that consciousness is a fundamental part of reality, the hard problem can be explained since consciousness is not arising from physical stuff anymore: it simply...

I just want to animate cracks appearing on a solid block, but nothing explodes or gets pushed out (please see ...

Let $\mathrm{G}$ be a complex reductive group and let $\mathrm{O}_g$ be the adjoint orbit of $g\in \mathrm{G}$. I wonder is the centralizer $\mathrm{C}_{\mathrm{G}}(\mathrm{O}_g)$ still a reductive group in general? If not, how about the identity component of $\mathrm{C}_{\mathrm{G}}(\mathrm{O}_g...

Is there any example of a locally conformally flat manifold that is neither a space form nor a product of space forms?

As title states, I'm interested in figuring out how to construct a model of $\mathsf{ZFC} + \neg\mathsf{Reg}$, preferably off any regular model $\langle M, \in_M \rangle$ of $\mathsf{ZFC}$ without any forcing shenanigans involved.

Is there a term for the relationship between two integers that have the same prime factors? For example, $6=(2)(3)$ and $12=(2)(2)(3)$. Can one describe this with something along the lines of "$6$ and $12$ are <term>" or "$6$ is <term> to $12$"? ETA: "Multiples" is indeed not what I'm after. $...

What is Tapscript? How is it different from script? Is it the same thing as "Leaf script"? How does it relate to Witness Script, miniscript and any other type of script used in Bitcoin transactions? How and when was it implemented? What can it be used for?

I understand that one way to know is if an English translation like the NKJV or NASB has words in italics. Then I can know that the English word is implied rather than actually stated in the original Hebrew or Greek. But, let's take an example like Genesis 15:6, which I have been studying. In the...

It's a well known result that the Gaussian integral $$\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$ evaluates to $\frac{\sqrt{\pi}}{2}$. This result can be obtained using double integrals with polar coordinates, among other things, but I'm particularly interested in evaluating this integral ...

Suppose two variables X1 and X2 are correlated and we know that X1 causes X2 and X2 causes X1. For example, leg strength and an interest in cycling interest might be correlated. And (suppose) we know that having stronger legs makes you more likely to take up cycling and cycling causes your legs t...

Is it acceptable in formal American English to pronounce the first vowel in "regret", "realize", and "return" as an open-mid front unrounded vowel as opposed to a close front unrounded vowel? Also, how were these words pronounced in Middle English?

I am trying to understand why chemical potential $= U/2$ is considered to be at half-filling in the case of the Hubbard Model Hamiltonian. So when I substitute this in its Hamiltonian, this is the equation I am getting $$ H = K.E-\frac{U}{2}\Sigma [n_{j,up}n_{j,down} + (n_{j,up} - n_{j,down})^{...

Abraham went to Mitsrayim c. 2000 BCE. At that time the Egyptians knew themselves as Kemet, not Misr. The earliest reference to the name Misr to my knowledge is from the Amarna Letters c. 1350 BCE. This is after the Hebrews reached Israel. How do we explain this?

The probabilistic method uses arguments from probability to prove deterministic statements. This has been applied to diverse fields such as combinatorics, topology and number theory. In this method, you constructs a random variable based on the theorem that you want to prove. Using probabilistic ...

I've been recapping an Amstrad PCW 9256 computer.

There are some high voltage, low capacitance capacitors that ...

I was just wondering if PEMDAS is realy needed in Math. I think that instead of trying to interpret math by using conventions, we just need to write math in the right order of operation from left to right. PEMDAS does not reflect the real life order of doing things. I am no Math expert, but if I ...

I am trying to construct a bifurcation diagram of the system $$dx/dt=yz+a,\quad dy/dt=x^2-y, \quad dz/dt=1-4x.$$ I've scoured the internet for pre-made bifurcation diagrams and found many (mostly of the logistic map). However, as the code is quite complicated I am not sure how to edit the code so...
