I'm having problems installing the spotify client on Ubuntu 14.04. I've installed the latest updates, but it didn't change anything.   First I ran:  deb http://repository.spotify.com stable non-free   Then I did:  sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 94558F59   After that I did:  sudo apt-get update   And then I did:  sudo apt-get install spotify-client   But it says   cannot find package spotify-client...
Hi everyone I'm attempting to install spotify, I've been running linux for less than 24 hours so please cut me some slack if this seems trivial. Here is a link to the webpage  and the example script.         Add this line to your list of repositories by editing your /etc/apt/sources.list    deb http://repository.spotify.com stable non-free    If you want to verify the downloaded packages, you will need to add our public key  sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 94558F59    Run apt-get update  sudo apt-get update    Install spotify!      sudo apt-get install spotify-client      would someone be nice enough to walk me through this? I'm not even sure where to start.
I am able to solve simple differential equations like :  $$\dfrac{dy}{dx} = 3x^2 + 2x$$  We simply bring $dx$ to other site and integrate.  But how do we find solutions of differential equations like :  $$\frac{d^2x}{dt^2} + \dfrac{kx}{m} = 0$$  ?  We have been told the solution is $x(t) = A\cos ( \omega t + \phi_o)$ where $\omega\ =\sqrt{\dfrac{k}{m}}$  but how do we actually find it? Updating Location of Point Features using XY Fields? I have changed the coordinates of couple points in the attribute table and I want to update the location. I have found the script that is working in field calculator.   Does anybody know how to write it using a Python script in ArcGIS Desktop (not in Field Calculator)?  def XYsetVALUE( shape, X_value, Y_value):    point = shape.getPart(0)    point.X = X_value    point.Y = Y_value    return point  __esri_field_calculator_splitter__ XYsetVALUE ( !SHAPE!, !X_COORD!, !Y_COORD! )   COORDINATE FIELD TYPE ------ STRING !!!! Which function ($f$) is continuous nowhere but $|f(x)|$ is continuous everywhere? Which function ($f$) is continuous nowhere but $|f(x)|$ is continuous everywhere?   I found this question , the question seems much interesting but for obvious reason it is closed there, I was wondering how to derive such a function? Add a time limit before you can vote on a post How do I create a master workbook in excel? In powerpoint we have something called a master slide.  I want the same idea for excel.  I want to create a template that I can work on with formulas and I want it to update all children files.  Example: I have a budget template.  This template has a budget listing all required equipments and their cost for a project.  We then have a formula that calculates the total cost of all equipment. I want to update only the template file with equipment and formulas, but I want the actual files (children) to contain the costs (because they might be different costs for different locations, but the rest of the budget and its formulas are shared).  Its pretty much exactly what a master slide in powerpoint is, if you've ever used that you should understand what I'm trying to do pretty easily.  One master file to store formulas, and a bunch of children files that store the data to be accessed by those formulas.  This way if a formula needs to be changed, the templates is adjusted and all other files update accordingly.  Any ideas?  I'd prefer not to have to use VB, and I'd also like a solution that works for both mac and windows.  Found  question but no answers.  I've already created a template, but that doesn't seem to update the other files when I modify it. I've searched online, but I have not found any clear instructions how to permanently add .sty files to my TeXShop installation. I'm using a Mac with OSX (TeXShop is a mac only program).  What is the best way of doing this? The one comprehensive set of instructions I found .   I've got as far as extracting the files (running LaTeX on the .ins and . dtx files) but after that I don't know what to do. I also don't understand how to update the index of my distribution, and whether there are particular OSX specifics (the instructions are for Windows). How to increase swap space? I have, by default, 250MB of swap space in Ubuntu, and I want to expand it to a larger size. I need 800MB, which I think will be enough to open several applications without having to hit the current limit of swap. I hope someone can help me. Getting command-not-found working under zsh How is Clan War Map position determined? When customers buy things from a store, you say:  (1) Customers give ABC Store business.  If I "turn this around", can I say:  (2) ABC Store obtains or acquires business from its customers.  Do these verbs work in (2)? Prove $\alpha \in R[[x]]$ is a unit iff $a_0 \in R$ is a unit Prove $\alpha \in R[[x]]$ is a unit iff $a_0 \in R$ is a unit.   $"\Rightarrow"$ suppose $\alpha \in R[[x]]$ is a unit, where $\alpha = \sum_{n=0}^{\infty} a_nx^n$  then there exists an inverse $\beta = \sum_{n=0}^{\infty} b_nx^n$   stuck at this spot,  $(\sum_{n=0}^{\infty} a_nx^n)(\sum_{n=0}^{\infty} b_nx^n) = \sum_{n=0}^{\infty}(\sum_{k=0}^{n}(a_kb_{n-k}))x^n$  A little mixed up on how this becomes $1 = \sum_{n=0}^{\infty}e_nx^n$ where $e_0 =1, e_{n&gt;0} = 0$ and why that would make $a_0b_0 = 1$ which would make $a_0 \in R$ a unit. I haven't tried the other direction yet.  EDIT  Maybe I get it, because we assumed this sum is a unit then its inverse exists and so the $x^0=1$ and all $a_ib_i=1$ thus $a_0b_0=1$ which gives $a_0$ is a unit in $R$ Usage of __slots__?

Two monitors when only having one in 13.10 I just did a fresh install of Ubuntu 13.10 64bit, and it says that I have 2 monitors, when I actually only have one    I have a Dell XPS 15 with Nvidia graphics card if that helps in anyway I just proved that any finite group of order $p^2$ for $p$ a prime is abelian. The author now asks to show that there are only two such groups up to isomorphism. The first group I can think of is $G=\Bbb Z/p\Bbb Z\oplus \Bbb Z/p\Bbb Z$. This is abelian and has order $p^2$. I think the other is $\Bbb Z/p^2 \Bbb Z$.   Now, it should follow from the fact that there is only one cyclic group of order $n$ up to isomorphism that these two are unique up to isomorphism. All I need to show is these two are in fact not isomorphic. It suffices to show that $G$ as before is not cyclic. But this is easy to see, since we cannot generate any $(x,y)$ with $x\neq y$ by repeated addition of some $(z,z)$.  Now, it suffices to show that any other group of order $p^2$ is isomorphic to either one of these two groups. If the group is cyclic, we're done, so assume it is not cyclic. One can see that $G=\langle (1,0) ,(0,1)\rangle$. How can I move on? Output of Logistic Regression Prediction I can't (vote to) close a question I voted to close before but then retracted? For example...  I closed a vote for 'too broad'. But then I realized I wanted to close it as a specific duplicate of another question instead. So I retracted my close vote.  That worked. But I can't now vote to close as duplicate and the title says I already voted to close.  Maybe this is intentional but it doesn't feel that way. Prove $\lim_{x \rightarrow 0} \frac {\sin(x)}{x} = 1$ with the epsilon-delta definition of limit. I have a site which is running under SharePoint 2013. Via REST I am trying to retrieve the file and folder directory for that site. There are several similar questions on this site related to recursively retrieving all of the files and folders for a given a folder:       The answers provided therein led me to the following URI:     /_api/web/Lists/GetByTitle('Documents')/Items?$expand=Folder&amp;$select=Title,FileLeafRef,Folder/ServerRelativeUrl   Which from what I can tell does retrieve all of the files and folders from the given starting path.  However, I am missing something. When reading through the returned XML I cannot figure out where a given file goes. Meaning that I have info on how to retrieve file bros.pdf, but cannot determine that it is in the documents/super/mario/ folder.  For the file items I've tried to retrieve the ServerRelativeUrl property, but have not succeeded though the folders seem to. Is there some identifier in the XML that I am missing? When doing a recursive RESTful query how do I determine where a given file belongs? Separate selected UV map vertices from surrounding vertices How do I break the selected UV map from its surrounding vertices? We are a team with three orgs. Development, UAT and Production.  We are trying to move away from changesets and manual copying and use various deploy mechanisms or scratch orgs but we cannot deploy org wide email addresses since it is not supported in the metadata api.   The problem is that since addresses cannot be deployed, workflows referencing them cannot either. And if we dont deploy all workflows some tests will fail and the environment will be wrong.  I would appreciate any help with this issue, thanks
