I'm running torbrowser on Debian. klipper saves the history of my clipboard. I would like to desactivate this feature for tor browser, so that I can use the copy-paste functions "locally", without sharing them with the rest of my system.  Is that achievable? Is this a linux-oriented question?
Is it possible, on Debian with Klipper running, to have a separate "clipboard stack" for a particular application?  I'd like the text that I copy in application Y not to be shared with all the other applications running.  All the solutions mentioned at  seems like overkill.
How to install folding at home (Folding@home FAHControl) on Ubuntu 19.10 How do I easily rename multiple files using command line? One of the ways I quickly rename files in Windows is   F2 &gt; Rename &gt; Tab (to next file) &gt; Rename ...   But in Ubuntu/Nautilus, I can't tab to next file. But being on Linux, I think there must be a command line alternative.  However, sometimes, I may want more control over how to rename specific files. In that case, perhaps its better to be able to tab to the next file Theorem 13.9 in these  is the polynomial spectral mapping theorem:     Theorem 13.9 For a polynomial $p$ we have $\sigma(p(T)) = p(\sigma(T))$.     My questions:   First direction: Why would $q(T) (p(T) - p(\lambda) I)$ be an inverse for $T - \lambda I$? Update: @RobertIsrael said that instead $(p(T) - p(\lambda) I)^{-1} q(T)$ should be $(p(T) - p(\lambda) I)^{-1}$ be? According to the lines in the proof above, we have $$ (p(T) - p(\lambda) I)^{-1} = ((T - \lambda I) q(T))^{-1} \overset{?!}{=} q(T)^{-1} (T - \lambda I)^{-1}, $$ but as $\lambda \in \sigma(T)$ by assumption, $(T - \lambda I)^{-1}$ doesn't exist, right? For the second direction: Why does $x_i \in \sigma(T)$ imply that $p(x_i) - \mu = 0$? I thought that $x_i \in \sigma(T)$ only implies that $T - x_i I$ is not boundedly invertible. Since $\mu \in \sigma(p(T))$ we have that $p(T) - \mu I = c \prod_{k = 1}^{n} (T - x_i I)$ is not boundedly invertible but how does that help?   In both statements there seem to be a notion of "a product of operators is not invertible iff all factors aren't invertible", but how can that be true? Consider i.e. shift operators on a sequence spaces such that $ST = I$, i.e. the left and right shift operators, then the above mentioned notion doesn't hold, right? Show that $a^2 \bmod b = (a \bmod b)^2 \bmod b$ Show that  $$a^2 \mathrm{\ mod \ } b = (a \mathrm{\ mod \ } b)^2 \mathrm{\ mod\ } b$$ for $ a, b \in \mathbb{Z}^+ $.  this was derived from an Informatics olympiad question. Characterizing all mobius transformations from unit disk to itself. All answers to this problem involve the following process:   Pick a point $a$ in the unit disk such that $T(a)=0$. Then, $T(a^*)=\infty$ if $a^*$ is the symmetric point $a^*=\frac{1}{\bar{a}}$ of a. Clearly, such a transformation is of the form $T(z)=\frac{z-a}{1-z\bar{a}}$. We might as well place a constant C in there: $T(z)=C\frac{z-a}{1-z\bar{a}}$. Then, most answers magically jump to replacing $C=e^{i\theta}$ in the formula and claiming the job is done.  Why does a function built so that it sends a point inside the unit disk to zero, and its symmetric point to $\infty$, be the one that preserves the unit disk? What's the motivation behind approaching this problem in that manner? Could one proceed bruteforce: with $|\frac{az+b}{cz+d}|&lt;1$ and arrive at the same function? For some reason this seems to me like somebody pulled a rabbit out of a hat. Once given the formula, I understand why it does the job, but why would somebody think that choosing a point inside the disk and building a function that sends it to zero create a mobius transformation that does the job? Redirect all requests to subdirectory except a few ip addresses Issue with Sorting Layers with an NPC and Tilemap I have a weird thing happening, that I can't quite explain.  I have two scenes, my starting town, and an Arcanist's shop.  When I go into the Arcanist's Shop, the Arcanist NPC stays on the same sorting layer (background layer 0) as my checkered tiles, and the table is background layer 1.  When I start the game, the NPC will switch between being "behind" the table, or on top of it whenever I reenter the Arcanist's Shop scene.  It seems to switch between background layer 0 and 1 with no cause.  I've double checked my sorting layers, they're all where they should be.  I've checked the camera's culling mask, it's fine.  I've checked to see if there are any weird components on anything in my shop scene, and there aren't  See the image attached, this is the same instance of the game, just different times when I enter the Arcanist's Shop.

Find an example where Markov's inequality is tight in the following sense: For each positive integer $a$, find a non-negative random variable $X$ such that $P(X\ge a)=E(X)/a$.   How to do this problem, I am really confused. Also, what is the definition of Markov's inequality? Referencing equation counter value in custom float caption I have used the float package to create an equation float, eqfloat, so I can add captions to equations. Within the eqfloat I used the equation environment to typeset the math.  I want to keep the right hand arabic numbering within parentheses that is added by the equation environment but I also would like the eqfloat caption below the equation to use the same number as the equation environment.  The following code achieves this by making the eqfloat use the same counter as the equation environment and then manually adjusting the equation numbering within each eqfloat.   Is there a better way to make the eqfloat caption reference the current value of the equation environment counter?  Is it possible to prevent the custom float environment from increasing the counter and only to reference the current value of the equation counter?  \documentclass[a4paper]{article}  \usepackage[margin=25pt, labelfont=bf]{caption} \usepackage{amsmath, amsfonts, pifont, float, color, url} \usepackage[pdftex, plainpages=false, pdfpagelabels, bookmarks=true]{hyperref}  \newfloat{eqfloat}{h}{eqflts} \floatname{eqfloat}{Equation} \makeatletter \let\c@eqfloat\c@equation \makeatother  \begin{document}     ...     \begin{eqfloat}         \begin{equation}             E = mc^2         \end{equation}         \addtocounter{equation}{-1}         \caption{Equation caption here.}         \label{eq:example}     \end{eqfloat}  \end{document} I was recently watching Episode 3 and a few clone wars episodes, and I found myself thinking during the opening battle between the Republic and General Grievous' forces above Coruscant, on a planet so densely populated where potentially thousands of inhabitants can be killed from a drifting capital class ship with a decaying orbit during space battles what defenses are in place?

Deriving Sum of a Geometric Progression I have a 10 stock portfolio and considering market conditions that are on the rise when this question in being asked, a few of them did hit their 52-week high price.  I would like to call myself a long term investor and I do not like to trade so much. If I take "Buy low sell high" as gospel then this is in my opinion a good selling position.  On one hand, I think I should lock my profit because stocks don't hit a 52-week high every day, but on the other hand, there is nothing wrong with the company and it is very well positioned to go up even further.  Any suggestions? I have to deal with a text classification problem. A web crawler crawls webpages of a certain domain and for each webpage I want to find out whether it belongs to only one specific class or not. That is, if I call this class Positive, each crawled webpage belongs either to class Positive or to class Non-Positive.  I already have a large training set of webpages for class Positive. But how to create a training set for class Non-Positive which is as representative as possible? I mean, I could basically use each and everything for that class. Can I just collect some arbitrary pages that definitely do not belong to class Positive? I'm sure the performance of a text classification algorithm (I prefer to make use of a Naive Bayes algorithm) highly depends on which webpages I choose for class Non-Positive.  So what shall I do? Can somebody please give me an advice? Thank you very much! How would I find the period of an oscillator with the following force equation?  $$F(x)=-cx^3$$  I've already found the potential energy equation by integrating over distance:  $$U(x)={cx^4 \over 4}.$$  Now I have to find a function for the period (in terms of $A$, the amplitude, $m$, and $c$), but I'm stuck on how to approach the problem. I can set up a differential equation:  $$m{d^2x(t) \over dt^2}=-cx^3,$$  $$d^2x(t)=-{cx^3 \over m}dt^2.$$  But I am not sure how to solve this. Wolfram Alpha gives a particularly nasty solution involving the hypergeometric function, so I don't think the solution involves differential equations. But I don't have any other leads.  How would I find the period $T$ of this oscillator?

These documents often do not have a proper date or rather the date is part of the title. However, Latex gives me a "n.d." output, and I am wondering what I can do for it to not give a "n.d." when there is no year given?    To make clear, the reason for why I don't want to use the "year" field is that I deal with very different kinds of documents, which may either have no date or the date is in the title, because of which I prefer to simply "hard-copy" the whole thing in the "howpublished"-section and need to suppress the year, if none is provided.
