This applies to Ubuntu 14.04 running in a VMWare environment on a OS X host.  Everytime I press the apple command key to e.g. command-tab to another (OS X) application, the HUD comes up in Ubuntu. Not the regular (small search box) HUD, but the big mondo one that looks a bit like the Apple launchpad, and is about equally useless.  I've tried disabling/changing the key binding in the system settings to use e.g. the backslash key. That works fine, on backslash, the HUD comes up. But on apple command key press, that big mondo special search HUD still comes up, no matter what I do.   Any help anyone?
I don't want to use the Super for that, I want to use Alt+Space instead.
How to create a generic array in Java? Due to the implementation of Java generics, you can't have code like this:   public class GenSet&lt;E&gt; {     private E a[];      public GenSet() {         a = new E[INITIAL_ARRAY_LENGTH]; // error: generic array creation     } }   How can I implement this while maintaining type safety?  I saw a solution on the Java forums that goes like this:  import java.lang.reflect.Array;  class Stack&lt;T&gt; {     public Stack(Class&lt;T&gt; clazz, int capacity) {         array = (T[])Array.newInstance(clazz, capacity);     }      private final T[] array; }   But I really don't get what's going on. Why are Harry's GoF dreams in the third-person? Who should I be damage buffing as Mercy C# Lambda expressions: Why should I use them? I have quickly read over the  documentation.  This kind of example has helped me to understand better, though:   delegate int del(int i); del myDelegate = x =&gt; x * x; int j = myDelegate(5); //j = 25   Still, I don't understand why it's such an innovation. It's just a method that dies when the "method variable" ends, right? Why should I use this instead of a real method? Can we get an alternative to the "That solved my problem!" button that doesn't make the presumption that it solved my problem? I.e. "Yes, that's the problem I have."  In some cases, SE (et. al.) answer something, but the answer really doesn't solve it, it was a "cop-out" -- a "we know there's a problem, but there's currently no fix or workaround". Can we get a button that indicates that "Yes, I acknowledge I have that same problem, and I may have even tried those solutions, but it's not solved by any means." button or something?  I get the purpose of it - make it more friendly and easier to remove duplicates, but I refuse to say "That solved my problem!" if I still have a problem (mostly on principle). I'd rather have a "Ah yes, that's my issue! But, it seems like there's no actual solution there."  As an example: Why does Unix store timestamps in a signed integer? Why is a signed integer used to represent timestamps? There is a clearly defined start at 1970 that's represented as 0, so why would we need numbers before that? Are negative timestamps used anywhere? Where did dedicated.abac.net. come from in my rDNS and PTR records? So I followed this guide to the letter:   I did so for 3 domains.  When I "test" the records and enter: host 64.150.176.81 on my linux machine, it shows me 81.172.150.64.in-addr.arpa domain name pointer 64-150-172-81.dedicated.abac.net.  when it should be showing me 81.176.150.64.in-addr.arpa domain name pointer 64-150-172-81.example.com.  Has anybody encountered a similar problem?  I am hosting with codero, not abac.net btw. lstlisting directly after section start removes margin before next section If I place an lstlisting directly after the start of a (sub)section, the margin before the following (sub)section (title) disappears.  Here is a an example document showing the issue:  \documentclass[twocolumn]{article} \usepackage{listings} \begin{document}  \section{Lorem ipsum} Consectetur adipiscing elit.  \begin{lstlisting} Lorem \end{lstlisting}  Sed quis ante nec mi volutpat congue eu id leo.  \section{Dolor sit amet} Suspendisse at lorem mattis, semper massa id, euismod risus.  \newpage  \section{Lorem ipsum} \begin{lstlisting} Lorem \end{lstlisting}  Sed quis ante nec mi volutpat congue eu id leo.  \section{Dolor sit amet} Suspendisse at lorem mattis, semper massa id, euismod risus.  \end{document}   And you can see the (annotated) result here:    Why is there no margin before the fourth section (title)? Is this a bug in my LaTeX environment (MacTeX-2013), or is this the expected behavior? Create Yosemite install disk on a Windows machine I have a 2009 Mac with a new blank SSD. I have a Snow Leopard install disk but it doesn't work (it was a replacement installer disk and has never worked), so I don't have a working OS X install.  I do have a Windows 7 machine.  How should I go about installing Yosemite? All instructions I can find require OS X at some point in the process. I can't even download it from the store unless I'm on a mac. I haven't logged onto my blog for years, and have, of course, forgotten the password. I click the 'Forgot' button and get a mail with a link, but that mail already says     Sorry, that key does not appear to be valid.   And sends me round the click to reset, receive a mail, click the link again etc. As if the timeout for password resets has been set to 0.5s or something.  This is a shared hosted blog, so I have full access to cPanel and all of the WP files via FTP, if that helps anything. What is the ideal data type to use when storing latitude / longitude in a MySQL database? Bearing in mind that I'll be performing calculations on lat / long pairs, what datatype is best suited for use with a MySQL database? The program ed, a minimal text editor, cannot be exited by sending it an interrupt through using Ctrl-C, instead printing the error message "?" to the console.  Why doesn't ed just exit when it receives the interrupt?  Surely there's no reason why a cryptic error message is more useful here than just exiting.  This behavior leads many new users into the following sort of interaction:   $ ed hello ? help ? exit ? quit ? ^C ? ^C ? ? ? ^D $ su # rm -f /bin/ed    Such a tragic waste—easily avoidable if ed simply agreed to be interrupted.  Another stubborn program exhibiting similar behavior is less which also doesn't appear to have much reason to ignore C-c.  Why don't these programs just take a hint? Sounds of the letter a How can I know, precisely, when to differentiate the sounds of the letter a, like in: apple and vault? How to adjust the breaking in the bibliography? Memory management in Objective-C The correct omission of the definite and indefinite articles Applying an ellipsis to multiline text Let $p$ be a prime number. If -1 is a square in $\mathbf F_p$, it means that there exists an element of order 4. So $p-1$ is divisible by 4 and therefore $p \equiv 1$ (mod 4). I wonder the converse is also true. Does $p \equiv 1$ (mod 4) mean the existence of an element whose square is $-1$ in $\mathbf F_p$? Function always continuous in a Sobolev Space? Hy everybody got a quick question. I know that all function F in a Sobolev Space has a continuous representative called U such as U=F almost everywhere.  Lets take for example: The Sobolev space on ]-1,1[    the function F(x)=0 on x&lt;0 and F(x)=1 x>0  we can't find a continuous representative because it would be on a larger interval let say ]-eps ,eps[ so not in a Sobolev space the function F(x)=x on x&lt;0 and x>0 and F(0)=1 where we could find the representative U=x   My question is: if F isn't continuous is it sure that it isn't an element of a Sobolev Space? It was given was given as a necessary condition in my course.  Thanks for the help.
