I found a project bike that was missing some things and I decided to fix it up. The first image is of the front brake which is missing the piece that clips onto the brake cable. The second image is of the rear brake which has the piece that the front brake needs. Question What is this piece calle...

Say my credit card has a limit of $3000 and I need to make a purchase of $10000. If I have the money, can/should I preload my credit card with $10000 and then make the purchase? Or is my purchase still limited to $3000? My point of using the credit card is for the cash back, not for borrowing mon...

I am designing a physics class library for Unity and would love to be able to hook and inject functionality into Unity's Rigidbody class, but it's my understanding that there is no way to do this directly while still being able to target all platforms.

I hope to get a PPL, IR, and possibly CPL someday. It looks like obtaining a student pilot certificate does not require anything except being 16 or older, knowing English, and completing a free application. Is there any reason not to get an SPC now, so I'll have one less thing to worry about if/w...

I know that two data sets can have the same Kendall's $\tau$ but different Pearson's $\rho$. What about the opposite? Can two different data sets have the same Pearson's $\rho$, but different Kendall's $\tau$? Or rather, if we know the correlation matrix Pearson's $\rho_{ij}$, does it correspond...

I want draw arrows between two column vectors like I have shown here. To make this image I rendered the two matrices in LaTeX like so: \[ \vec{P}=\begin{bmatrix} A_1\\ A_2\\ A_1\\ A_3\\ \cdot\\ \cdot\\ \cdot\\ A_6\\ A_5 \end{bmatrix} \qquad{\longrightarrow}\qquad \begin{bmatrix} A_1\\ A_...

I was looking at Garber files of the boost PFC reference designs by TI for my own 300W SMPS. I noticed that most of their design don't make full use of the plane by filling them with a ground pour for example [image of PMP40766]: *top layer yellow and bottom layer blue. All of their boost SMPS d...

The title pretty much explains everyrthing. Since there is a huge amount of IPv6 addresess, couldn't every device just use a global unicast address? What is the practical use of unique local IPv6 addresses? Thank you all in advance.

The WiFi on my MacBook Pro Unibody Mid 2012 15'' stopped working a few weeks ago and shows "Wi-Fi: no hardware installed". After searching online, I found this post here MacBook is displaying the message "no hardware installed" when I click on Wi-Fi and here Bluetooth and wifi stopped working N...

My world was colonized by spacefaring humans who lost the vast majority of their technology in an unknown catastrophe at least 12,000 years before the present. They have now redeveloped roughly up to the point of Late Medieval technology (with some adaptations to the conditions of my planet). We ...

I was looking online to see if this argument was a fallacy, but I couldn't find anything. It reminds me of the problem of induction, whereby one cannot predict what the future holds based on past events of some one or more things happening. I'm leaning toward to the belief that for someone to argue

My daughter has created a piece of music for her B-Tec music production class in which the time signature changes, but the tutor is trying to argue that this is not correct.

A german native speaker corrected part of a sentence I wrote from "dem zen Buch" to "dem Zen Buch". I couldn't quite get it. Why do we capitalize the adjective here?

I am tasked with solving a question for a qualifying exam, but I am a little lost about this question. Let $\eta$ and $\xi$ be two independent standard Gaussian random variables. Find $\mathbb{E}(\xi\eta \mid \xi - 2\eta)$. My attempt: My main idea is to show that $\operatorname{Cov}(\xi-2\eta,...

I'd like to write a %*% method for a base matrix subclass. My subclass is an S3 class and the documentation of help("%*%") says that %*% is a S4 generic. I've written methods for S3 classes for S4 generic methods before using methods::setOldClass() and methods::setMethod() and I've looked at th...

Let's consider a point particle at rest in space relative to an observer. Without a coordinate system, the observer can still determine that the particle occupies a specific point in space. However, for an observer who is moving relative to the original observer, the point particle appears to occ...

I was wondering if there are infinitely many even positive integers $2k$ for which there exists an exotic sphere of dimension $2k$. Here by an "exotic sphere" of dimension $n$ we mean a smooth manifold homeomorphic but not diffeomorphic to the standard $n$-sphere. The odd-dimensional case is desc...

Is there a way to get a file from a remote server you are connected to via ssh, by simply running a command like get file within the ssh session? Is there a method, or pre-existing tool, to do this? Its slow to copy and paste the path into an sftp command in another terminal, so it'd be preferabl...

I'm trying to identify a 1950's "pulp" sci-fi novel I read long ago. The cold war is still happening in its timeline. A very rare mineral is discovered that makes an FTL engine possible. To get enough mineral for even one engine, a collosal manhattan-project like effort was undertaken to isola...

Question: What are influential, canonical, or otherwise useful works considering low-probability events? My background: Applied or computational statistics, not theory or pure statistics.

I usually see べき nominalized as べきは. Is it grammatically correct or just a casual way of saying? How is it different form べきことは?

UML is generally taught as a standardized way of diagramming software, however, I've heard recently that there's an actual grammar behind it. I've searched the UML specification and haven't found much that was sufficient in terms of describing an actual grammar. Tools like PlantUML seem to have ...

So w...

Working source first, permission sets and profiles have a low "signal to noise" ratio where the signal is the content of the XML elements and the noise is the element layout and the elements themselves. And many of us have multiple permission sets to manage that each can be easily 10,000+ lines l...

There is a famous Bava Metzia 62a paskens that in a case where there are two people and there is only enough water for one to survive, the owner of the water drinks it and lets the other die: ורבי יוחנן האי וחי אחיך עמך מאי עביד ליה מבעי ליה לכדתניא שנים שהיו מהלכין בדרך וביד אחד מהן קיתון של מי...

I have read this PSE post Finite Temperature Quantum Field Theory, saying that In a QFT at finite temperature, we consider the Euclidean time to be periodic, i.e. we consider a theory on the manifold $\mathbb{R}^{d−1}×S^1$, where the spatial coordinates are in $\mathbb{R}^{d−1}$ and the time coo...

Recently, I became interested in trying to document the grammar and phonologies of colloquial or "street" forms of English.

Why LLMs learn so fast during inference, but, ironically, so slow during training? That is, if you teach an AI a new concept in a prompt, it will learn and use the concept perfectly and flawless, through the whole prompt, after just one shot. Yet, if you train it in just a single sample, it will ...
