I'm trying to find the infinite sum that is defined by:  $$ 3 \cdot \frac{9}{11} + 4 \cdot \left(\frac{9}{11}\right)^2 + 5 \cdot \left(\frac{9}{11}\right)^3 + \cdots $$  However, I do not know of any known formula to do this. Am I missing something really simple? Thanks! Finding the id of a parent div using Jquery Where do the files go if you mount a drive to a folder that already contains files? I just accidentally mounted a new drive to a folder that already contained files.  I don't care about them and have them somewhere else, but that folder appears empty now.  I'm curious what happened to the files.  Are they simply deleted by Linux? I find myself frequently needing to rename different files with mv that are in deep directories:  mv /a/long/path/to/a/file.txt /a/long/path/to/a/file.txt.bak   But I don't want to retype the full path name. Is there a quick shorthand or alias that I could use? I.e.:  $ mv /a/long/path/to/a/file.txt file.txt.bak $ ls /a/long/path/to/a/file.txt.bak a/long/path/to/a/file.txt.bak   (note: this is for straightforward, single file renames in different directories at different times, not for ) Can we insert or update FieldSets using apex code? Although we can create or update fieldsets using salesforce UI but Is there any way to insert or update FieldSets using apex code (using metadata or API calls) ? I am new to Stack  Exchange and I think it's very impressive.  One thing bothers me is that because it is so far down the line, I don't think beginners stand a chance of growing.  As time goes on, more and more questions are being answered and therefore if someone asks something with a really basic answer you can just comment. However, beginners can't comment until they have a reputation of 50. The only way they can build up is by answering questions. But if they answer a basic question long winded, they will be voted down because not so much effort was needed or because its already a duplicate and will lose the bit of reputation they have earned.  Can you tell me the future for beginners? I am using the  for GNOME Shell, similar to the old Maximus extension for GNOME 2 / Unity. When I maximise a window, the title and menu bars are hidden.  But I don't want the minimise, maximise or close buttons to appear in the Activity Bar. , so I have been able to remove the minimise and maximise buttons by disabling them in Tweak Tool.  How do I similarly disable/remove the close (X) button?  (I guess this is the opposite of ) Logistic regression cost surface not convex I am building a simple logistic regression model on 2D data. Here is the input I use.    I built a logistic regression model using this data and it successfully is able to find the discriminating line between these two classes. Here is the separating line found by my program:    Also, just for debugging, I plotted number of iterations vs J(theta), which also looks fine:    Now, confusing part comes into play. I am investigating the cost surface of this model that the logistic regressions is doing the gradient descent on. I am considering three different loss functions. Sum-of-squared loss, hinge-loss, log-loss.  Hinge loss:    Log-loss:    Sum-of-squared loss:    As far as I know, both hinge loss, sum-of-squared loss and log-loss should produce a convex surface. When I look at my surfaces, however, sum-of-squared surface does not look convex to me. Why is that the case?  For convenience, here is the two critical functions from my code:  function retval = J(X, y, theta)     M = size(y, 1);     % sum of squared error     retval = (1/(2*M)) * sum((h(X, theta) - y).^2);  endfunction  function retval = h (X, theta)     % logistic     retval =  1 ./ (1+ exp(-1 * (X * theta))); endfunction Can I disable GNOME legacy tray in 17.04?

What do I need to get photos with a unifom black background (not with post)? Often i see portraits such as the one below and like the way they look. I wanted to know can I get this look in my shots.  I am sure there are professional materials you can get to outfit a studio that will deliver such results. I have no clue what these items would be, can i get clued in?  Also, I was wondering if there is a DIY way to achieve this as well. Maybe with a black bed sheet or something?  I want to set something up in a room in my house for studio type shots. I am looking to get an idea of what items I need to get this done and how the setup should go. How to edit 'etc/hosts' file in non-rooted phone?

Expected Value Of Number of Removals From Urn Here's the question: "An urn contains b blue balls and r red balls. You repeatedly and independently remove balls from urn (without returning them) until the first blue ball is drawn. All balls currently in the urn have an equal probability of being selected each time a ball is removed. Define the random variable X as the number of balls that are drawn (number of red balls that are removed plus the first blue ball that is removed). Find E[X], the expected value of random variable X."  I'm having trouble finding a closed form expression for the expected value. Here's the work I've done: Add review queues to Android app I am a beginner using QGIS (1.8.0 Lisboa) on a Mac (OS X 10.6.8 Snow Leopard). I work on a file with two layers in the following sequence (top to bottom):    a vector polygon layer with a few outlines of various buildings in France and Italy (CRS: EPSG:4326 - WGS 84 - "on the fly" re projection is activated ) a Google satellite layer uploaded via open layer plugin.   Sometimes when changing the scale (scrolling in and out) the Google layer updates a little wrong in size or position compared to the polygon layer. But as soon as I "pan" the map everything reconstructs right. Now the problem I have concerns the print composer.  The result of any kind of export - pdf, or image or svg - of my map (vector layer + Google layer in the background) differs from what is shown in the preview of the print composer: the vector layer and the Google layer positions are mismatching and in a different scale. I can send some pictures showing screenshots of the print composer preview and the final results if required.  I tried almost everything:    new files with different CRS settings "cache" update preview "render" update preview different paper sizes,  different scales,   The problem appears only using an open layer map (Google, OpenStreetMap...). If I try the same using two vector layer (shapefile) - one with the buildings, another one with the city in background - everything works out great.  ...exasperating! Since it is a real important research project I would be very grateful for some help and tips.
