I am having a hard time getting my delete button to remove an item dynamically. When I add a new ingredient the button appears but does not have functionality.  $(document).ready(function () {         getRecipe();         $(".btn-primary").on("click", addIngredient);         $(".btn-default").on("click", deleteIngredient);     });      var recipe = {         title: "Pizza",         servings: 4,         ingredients: ["cheese", "sauce", "flour", "pepperoni"]     };      var button = "&lt;button type=\"button\" class=\"btn btn-default delete btn-xs\"&gt;&lt;span class=\"glyphicon glyphicon-minus-sign\"&gt;&lt;/span&gt;&lt;/button&gt;";      function getRecipe() {           $("#title").append(recipe.title);         $("#servings").append(recipe.servings);           for (var i = 0; i &lt; recipe.ingredients.length; i++) {             $("#ingredients ul").append("&lt;li&gt;" + recipe.ingredients[i] + " " + button + "&lt;/li&gt;");          };     };      function addIngredient() {         var newIngredient = $(".form-control").val();         $(".form-control").val(newIngredient);         $("#ingredients ul").append("&lt;li&gt;" + newIngredient + " " + button + "&lt;/li&gt;");      };      function deleteIngredient() {         $(this).closest("li").remove();     };
I have a bit of code where I am looping through all the select boxes on a page and binding a .hover event to them to do a bit of twiddling with their width on mouse on/off.  This happens on page ready and works just fine.  The problem I have is that any select boxes I add via Ajax or DOM after the initial loop won't have the event bound.  I have found this plugin (), but before I add another 5k to my pages with a plugin, I want to see if anyone knows a way to do this, either with jQuery directly or by another option.
I have the following code that will remove lines with the pattern banana and 2 lines after it:  sed '/banana/I,+2 d' file   So far, so good! But I need it to remove 2 lines before banana, but I can't get it with a “minus sign” or whatever (similar to what grep -v -B2 banana file should do but doesn't):  teresaejunior@localhost ~ &gt; LC_ALL=C sed '-2,/banana/I d' file sed: invalid option -- '2' teresaejunior@localhost ~ &gt; LC_ALL=C sed '/banana/I,-2 d' file sed: -e expression #1, char 16: unexpected `,' teresaejunior@localhost ~ &gt; LC_ALL=C sed '/banana/I,2- d' file sed: -e expression #1, char 17: unknown command: `-' SQL Server 2008 R2 SP1  My company uses the Great Plains (GP) financial system with several customizations.  Our Value-Added-Reseller (VAR) for GP has setup most of these customizations in a separate database from the GP data called DYNCUSTOM.  In the DYNCUSTOM database is a View that is merely a SELECT * FROM a table in the GP company database (called PARTS).  I was approached by a user having problems trying to select on this view.  The error he was getting:  Msg 229, Level 14, State 5, Line 2 SELECT permission denied on object 'BM010415', database 'PARTS', schema 'dbo'   I looked at how his login was mapped and he had a database user in the DYNCUSTOM database belonging to a database role that was granted select on the view.  However, he did not have a database user in the PARTS database.    Usually the intent of a view is so that one can grant select permissions on the view without exposing access to the underlying table.  With SQL Server however, if the view crosses databases does it then change the security context being used?  Therefore, the user would also need a database user in the PARTS database as well as granted select access to the underlying table? $f:I=[\pi,2\pi]\to \mathbb{R}^2$ be given by $f(t)=(\cos t,\sin t)$  which of the following are necessarily correct?  $1$. $\exists t_0\in I$ such that $f'(t_0)=\frac{1}{\pi}(f(2\pi)-f(\pi))$  $2$. $\nexists t_0\in I$ such that $f'(t_0)=\frac{1}{\pi}(f(2\pi)-f(\pi))$  $3$.$\exists t_0\in I$ such that $\pi||f'(t_0)||\ge ||(f(2\pi)-f(\pi)||$  $4$. $f'(t)=(-\sin t,\cos t)\forall t$  $4$ is clearly true, $1$ is true by Mean Value Theorem as $f$  satisfies all the conditions of MVT? have no idea of $2$ and $3$, Thank you for help How to save a copy of a multiplayer world in the new 0.7+ menus? How do you save a joined game after the 0.7.1 update? The menus have all changed since 0.6.x and I can't find the option to save a copy of a joined world anymore. (My friend has got a diamond house on survival and I want to save it but it doesn't let me!) Is there any anti-gravity material? I want to know if there is any  material. I am thinking of making flying vehicles which are made up of anti-gravity material so that they will not experience any gravity on them and can easily take off and be more fuel efficient. Is there any such thing? Or any workaround? How to construct an example of a probability distribution for which $\mathbb{E}\left(\frac{1}{X}\right)=\frac{1}{\mathbb{E}(X)}$ holds, assuming $\mathbb{P}(X\ne0)=1$?    The inequality which follows from Jensen's inequality for a positive-valued RV $X$ is like $\mathbb{E}\left(\frac{1}{X}\right)\ge\frac{1}{\mathbb{E}(X)}$ (the reverse inequality if $X&lt;0$). This is because the mapping $x\mapsto\frac{1}{x}$ is convex for $x&gt;0$ and concave for $x&lt;0$. Following the equality condition in Jensen's inequality, I guess the distribution has to be degenerate for the required equality to hold. A trivial case where the equality holds is of course if $X=1$ a.e. Here is an example I found in a problem book: Consider a discrete random variable $X$ such that $\mathbb{P}(X=-1)=\frac{1}{9}, \mathbb{P}(X=\frac{1}{2})=\mathbb{P}(X=2)=\frac{4}{9}$. It is then easily verified that $\mathbb{E}\left(\frac{1}{X}\right)=\frac{1}{\mathbb{E}(X)}=1$.   This example shows that $X$ need not be positive (or negative) a.e. for the equality in the title to hold. The distribution here is not degenerate either.  How do I construct an example, possibly like the one I found in the book? Is there any motivation? Increase resolution to 4K in VMware or Virtualbox I have a laptop with a 4K (3860×2160) display, but there are a lot of problems. A lot of virtualization programs aren't compatible with 4K resolution.  VMware Workstation and VirtualBox don't support 4K display in the list of the display's resolution. How I can set the resolution of the display in a virtual machine to 4K? How to convert every pixel of raster picture to square objects in Illustrator? I had parked my follower at an inn with a bunch of valuable items that I didn't want to carry. I guess I have been out a bit too long as this message appears:      Your follower tires of waiting and leaves.    There have been other situations where my follower has mysteriously disappeared as well.  How can I find my follower when they get up and leave or disappear into thin air? Calculate the limit including binomial coefficients $\lim\limits_{n\to\infty}{\sum\limits_{k=n}^{5n}{k-1 \choose n-1}(\frac{1}{5})^{n}(\frac{4}{5})^{k-n}}$  It's clear that we can simplify the limit a little bit, after which we get:  $\lim\limits_{n\to\infty}{(\frac{1}{4})^{n}\sum\limits_{k=n}^{5n}{k-1 \choose n-1}(\frac{4}{5})^{k}}$  I could further simplify the expression, but I feel like there's a more elegant solution.   Give me a hint, please I am wondering if the mass density profile $\rho(\vec{r})$ has been characterized for atomic particles such as quarks and electrons. I am currently taking an intro class in quantum mechanics, and I have run this question by several professors. It is my understanding from the viewpoint of quantum physics a particle's position is given by a probability density function $\Psi(\vec{r},t)$. I also understand that when books quote the "radius" of an electron they are typically referring to some approximate range into which an electron is "likely" to fall, say, one standard deviation from the expectation value of its position or maybe $10^{-15}$ meters.  However it is my impression that, in this viewpoint, wherever the particle "is" or even whether or not the particle "had" any position to begin with (via the Bell Inequalities), it is assumed that if it were (somehow) found, it would be a point mass. This has been verified by my professors and GSIs. I am wondering if its really true.  If the particle was truly a point mass then wherever it is, it would presumably have an infinite mass density. Wouldn't that make electrons and quarks indistinguishable from very tiny black holes? Is there any practical difference between saying that subatomic particles are black holes and that they are point masses? I am aware of such problems as Hawking Radiation although at the scales of the Schwarchild radius of an electron (back of the envelope calculation yields $\tilde{}10^{-57}$ meters), would it really make any more sense to use quantum mechanics as opposed to general relativity?  If anyone knows of an upper bound on the volume over which an electron/quark/gluon/anything else is distributed I would be interested to know. A quick Google Search has yielded nothing but the "classical" electron radius, which is not what I am referring to.  Thanks in advance; look forward to the responses.

I am outlining the image using the pen tool.  Photoshop insists that the pen tool produce closed loops in order for me to use the "Stroke path..." tool.  Why is this? How does remittance work? How does it differ from direct money transfer? I have a bank account in Germany in which I receive my salary in Euros. I want to deposit a part of it in my Indian bank account for personal savings. My Indian bank account is in INR. As I see it, I have two options:   To use a remittance service that converts my Euros into INR and deposits in my account. I am not sure how it works. The service (which I know is reliable) I signed up for asks me to deposit Euros in a certain account ("funding") which will be converted to INR and deposited in my account. How does that work exactly? Use my bank's service to make a international bank transfer to my account. Is that even possible, given that my Indian account is in INR? Will I incur higher conversion fees and lower exchange rate?   In general, what are the pros and cons of each of the above methods? And are there any other methods?

What is the word which describes the absence of formless, of long procedure with bureaucrats? I was thinking about formsless but it sounds weird... I've seen examples like this:   public class MaxSeconds {    public static final int MAX_SECONDS = 25; }   and supposed that I could have a Constants class to wrap constants in, declaring them static final. I know practically no Java at all and am wondering if this is the best way to create constants. How can a quasar be 29 billion light-years away from Earth if Big Bang happened only 13.8 billion years ago? I was reading through the Wikipedia article on  and came across the fact that the most distant Quasar is 29 Billion Light years. This is what the  exactly says      The highest redshift quasar known (as of June 2011[update]) is ULAS-J1120+0641, with a redshift of 7.085, which corresponds to a proper distance of approximately 29 billion light-years from Earth.   Now I come to understand that the  singularity is believed to be around 13.8 Billion years ago.  So how is this possible? Does the presence of such a quasar negate the Big Bang Theory?   I'm not a student of Physics and was reading this out of (whimsical) curiosity. Is there something I'm missing here or the "proper distance" mentioned in the fact is a concept that explains this?  Edit: My Bad! Here's how..  A simple google search led me to  which says the farthest quasar found is 12.9 billion LYs and not 29 billion. So in the end we have just proven that wikipedia needs more moderation. I'm using Windows 7 as the host machine with VMWare Workstation 9. I created a virtual machine Ubuntu Desktop 12.04 LTS 64 bit version. There are two options for log in, Ubuntu and Ubuntu 2D. Whenever I log in to Ubuntu, the task bar will not show up, is like having a black margin all around the desktop background and only the center is visible.  I wish I could attached a pic, but I need at least 10 reputation.  When I move my mouse over the left side of the desktop I can see that something is there but it is shown only as a black square. I tried deleting the virtual machine I created for Ubuntu and re-installed it, but it keeps appearing like that.  When I switched to log in with the Ubuntu 2D version everything worked alright. I could see the task bar, the icons, the clock etc. What might be causing this problem?
