How common are arXiv delays? (putting a paper on hold status?). I have recently (yesterday) submitted my first paper on arXiv, it was supposed to show up a while ago, however the status of the paper was changed to on hold. How common is this? Also is it because I'm submitting my first paper on arXiv? Also how many days does it generally takes for the paper's announcement after on hold?
I have recently submitted a paper to arXiv, but the arXiv moderators put my paper in status "on hold", because they have to make a decision on the right classification for the paper.   To those who have experienced a similar situation, how long did it take before they made a decision and published the paper on the arXiv? I just want to have an idea of how long I will have to wait.
What is the size of a boolean variable in Java? Can any one tell the bit size of boolean in Java? I want to know, is there a way to make a tungsten lightbulbs filament withstand a mass amount of thermal shock while still producing a vast amount of heat? Find no. of non negative integer solutions of $a+2b+3c = 200$ I want to find number of the non negative integer solutions of $a+2b+3c = 200$ (answer can contain $a,b,c = 0$)  Example one of the solutions is $a = 100, b = 50, c = 0$  I used stars and bars trick and here i get is  $\dfrac{\dbinom{200+2}{2}}{2 \times 3}$ but it is incorrect  any type of math is welcomed    what I have learnt from stars and bars technique is to find the solutions of $x+y = n , x,y,n &gt; 0$ are positive integers but I am confused with equation of type $ax+by = n$ where $a , b&gt; 1$ ubuntu 14.04 login loop problem Using fflush(stdin) Does a percentage quantity take singular or plural verb agreement? Does a percentage require a singular or plural verb, for example, do we say ten percent "go" or "goes"? Does an unbalanced sample matter when doing logistic regression? No updates since a long time Using Ubuntu, I have a habit of running: sudo apt update sudo apt upgrade   on every startup. But for a month, I guess, there have been no updates whatsoever. The message shows: All packages are up to date  Now I am starting to worry. Can there be a fault in my update manager? As far as I know, I've made no changes to the package manager settings. But no updates for almost a month seems kind of weird. Any feedback would be helpful. Thanks.

An unclear sentence in the book "Griffiths, Harris-Principles of algebraic geometry" Let $X$ be a complex manifold and consider a holomorphic vector bundle $\pi:E\to X$ of rank $r$. By the usual correspondence between vector bundles and locally free sheaves, we consider $E$ as a sheaf by abuse of notation. We denote with $\mathscr A_X^{p,q}$ the sheaf of $C^\infty$ $(p,q)$-differential forms on $X$ and we define: $$A^{p,q}(E):=\Gamma(X,\mathscr A^{p,q}\otimes_{\mathscr O_X} E)$$ $$A^k(E):=\bigoplus_{p+q=k}A^{p,q}(E)$$  Now suppose that $\nabla:A^\bullet(E)\to A^\bullet(E)$ is a linear connection on $E$, then the curvature operator is defined as: $$\nabla^2:A^0(E)\to A^2(E)$$ where $\nabla^2$ is the composition of the maps $\nabla: A^0(E)\to A^2(E)$   and $\nabla: A^1(E)\to A^2(E)$. One can show that $\nabla^2$ is $C^\infty(X)$-linear.    I don't understand the following sentence from the Griffiths-Harris book at page 75 (I rephrase it by using my notation):     Since $\nabla^2$ is $C^\infty(X)$-linear, then it is induced by a bundle map $E\to\bigwedge^2T^*X\otimes E$, or in other words, $\nabla^2$ corresponds to a global section $\Theta$ of the bundle $\bigwedge^2T^*X\otimes\operatorname{Hom}(E,E)$.   I absolutely don't understand how I can see the operator $\nabla^2$ as the section $\Theta$. Re-use Mavericks install file I have three Macs I want to upgrade to Mavericks.

Logical Volume, Physical Volume and Volume Groups How fast would the Earth need to spin for us to feel weightless? It's a classic question with many answers all over the Internet, but none here so I figured I'd ask it:  How fast would the Earth need to spin for a person (or anything for that matter) to feel weightless while on the surface at the equator?    In this situation everything on the Earth's surface would essentially be in orbit around the Earth at the radius of the Earth's surface (let us assume the atmosphere was also spun up to this angular velocity so there would be no air drag slowing things down).  Let us also say by "surface of the Earth" we mean mean sea level.  You can decide for yourself if/how to factor in the bulge of the Earth.  You can assume that the Earth somehow is able to maintain its present shape while spinning up.  Any comments on whether an Earth spinning slightly faster than this speed will cause it to break apart or not will also be appreciated. Minimum requirements of Ubuntu 20.10 Does anyone know what are the minimum requirements to install Ubuntu 20.10? Benefits of Toad houses I have a few red Toads and a Toad is just hanging out in town.

How prove this $\prod_{1\le i<j\le n}\frac{a_{j}-a_{i}}{j-i}$ is integer The phrase "let alone" I notice that "let alone" is used in sentences that have a comma. The structure of the sentence is what comes before the comma is some kind of negative statement. Right after the comma is "let alone," followed by the rest of the sentence.  What does "let alone" mean here? Does it mean the same thing as "or even?" Can someone explain this phrase and sentences that have it? All  I just install a fresh new Ubuntu 16.04 on my new desktop which has a 8th generation Intel CPU i5 8600K. When OS installed, I found there is only one option in display setting: 1024 x 768 (4:3),  My monitor is a HDMI monitor with 1920x1080 resolution  Do anyone have any idea how to make the resolution setting right? Thanks.  BTW. I do not install any graphic card, I use the internal GPU of Intel What rules govern forced removal from flights (due to overbooking)? I was recently surprised to see  because his flight was overbooked.  He was reportedly a doctor who needed to see patients the next morning, so he did not really want to get off, justifying the use of force.  I knew that airlines could overbook flights and deny boarding to some passengers, but I thought that kind of boarding denial would happen at the gate and that once folks had been let on, those denied boarding would be those arriving later to the gate.    Why or in what conditions is this kind of forcible removal considered OK?    Clarification following close votes from people who think this question is primarily opinion-based: By "OK" I mean the sense of "legally OK," "officially accepted," "instantiated as policy," "sanctioned by authorities," or "OK according to the regulations and policies and laws and whatever other formal rules govern forced removal from flights due to overbooking." Whether or not you personally consider it socially acceptable does not matter as an answer, unless you have formalized that into a citeable adopted form that governs what happens and want to explain the reasoning behind that rule.
