Comparing objects of NSArray1 to NSArray2
Finding out NSArray/NSMutableArray changes' indices
I am moving from Egypt to the Netherlands and I need to take my PC with me. I won't be taking the monitor, just the case, but I'm wondering what the best way would be.  Am considering taking it as carry-on because I'm allowed 8kg and at least then I can handle it myself. Has anyone done this before and can give me tips or warn me that this doesn't work? Would putting it in my normal suitcase as checked baggage be a better idea? I am talking about when you click on the icons in the dock This command gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ launcher-minimize-window true  which works for Unity Launcher, (obviously) does not work.

In Maven, dependencies are usually set up like this:  &lt;dependency&gt;   &lt;groupId&gt;wonderful-inc&lt;/groupId&gt;   &lt;artifactId&gt;dream-library&lt;/artifactId&gt;   &lt;version&gt;1.2.3&lt;/version&gt; &lt;/dependency&gt;   Now, if you are working with libraries that have frequent releases, constantly updating the &lt;version&gt; tag can be somewhat annoying. Is there any way to tell Maven to always use the latest available version (from the repository)? Find the volume of a cone whose length of its side is $R$ How can i compute the volume of a cone whose length of its side is $R$ and the vertex of the cone forms an angle $2θ$ .  The top cone is a cap of a sphere of radius $R$.    I tried to solve first in 2 dimension and then use solid of revolution:    Some help please to find the volume of this cone. Movie with "Where do the tubes go?" I'm trying to find a movie with an underground facility with people wearing white suits. The people have been affected such that they show no curiosity. There is one person that does and asks one of his co-workers where a tube leads to.      At the end there is an uprising where everyone gets to see the surface and sunlight.   What is the name of this movie? Note that this is only focusing on Minecraft Java Edition, and for versions 1.13+. I am predominantly looking for a solution that does not require any external programs (like MCEdit or NBTExplorer) and will work in just plain vanilla Minecraft, although if the only solution doesn't fit these criteria, I'll still take it (since having a solution is better than no solution!) Essentially, I am looking for a way to put a phrase (meaning essentially there are two or more words and spaces are involved) on a Minecraft scoreboard. This is what I mean by 'phrase': One two three, 1 2 3 These are not 'phrases': OneTwoThree, One-Two-Three, One_Two_Three, 1-2-3, etc. However, it seems like the only way to add text to an objective on the scoreboard is to add a &quot;fake player&quot;, via /scoreboard  players add [playername] [objectivename] [score], which shows the [playername] and the [score] part of the command on the scoreboard. However, since player names can't have spaces at all, it means that you can't have a phrase shown on the scoreboard. I have seen on many servers scoreboards that do have phrases listed on the scoreboard, but I have no idea how they do this (probably because of plugins that can do this sort of thing).  I did notice that teams can be given display names that can have spaces, so is there a way to display the team name on the scoreboard (thus being able to put phrases on there?)? Overall, my main question would be &quot;Is there a way to use spaces on the scoreboard (excluding the objective name) in vanilla Minecraft? Is there a "win64" identifier in Qmake project files?  documentation does not mention other than unix / macx / win32.  So far I've tried using:  win32:message("using win32") win64:message("using win64") amd64:message("using amd64")   The result is always "using win32".  Must I use a separate project-file for x32 and x64 projects, so they would compile against correct libraries? Is there any other way to identify between 32-bit and 64-bit environments? Is there a grammatical term for moving a word to the front or back of a sentence? How to Check If A Plugin Is Enabled Through API? How to reduce space between image and its caption? What does 1x1 convolution mean in a neural network? I am currently doing the Udacity Deep Learning Tutorial. In Lesson 3, they talk about a 1x1 convolution. This 1x1 convolution is used in Google Inception Module. I'm having trouble understanding what is a 1x1 convolution.  I have also seen  by Yann Lecun.  Could someone kindly explain this to me? Can I open Microsoft Word and Excel files? every planar graph can be expressed as a union of five edge-disjoint forests How can I prove that every planar graph can be expressed as a union of (maximum) five edge-disjoint forests?  Only thing I can think about is going somehow like the $5$ color theorem but I get stuck in the middle. Or with induction, but still something doesn't fit. Can you help? Is there a Ubuntu sanity check? Is there a standard procedure to 'unit test' an Ubuntu system against the deb packages?  Assume, a system has ubuntu-desktop installed according to the package manager. Can I find out, whether the file system has all the files in ubuntu-desktop and dependencies?   related question: C++ guarantees that variables in a compilation unit (.cpp file) are initialised in order of declaration. For number of compilation units this rule works for each one separately (I mean static variables outside of classes).  But, the order of initialization of variables, is undefined across different compilation units.  Where can I see some explanations about this order for gcc and MSVC (I know that relying on that is a very bad idea - it is just to understand the problems that we may have with legacy code when moving to new GCC major and different OS)? If $f \circ g$ is surjective, then f is surjective Let $f: X \rightarrow Y$ and $g: Y \rightarrow X$  If $f \circ g$ is surjective, then f is surjective, too.  I think that is true.   Question: How can I proove that? I have so far:   $\forall y \in Y: \exists x \in X : f(x)=y$  $\forall x \in Y : \exists y \in Y : f \circ g(y)= x$ I'm building an application where I should capture several values and build a text with them: Name, Age, etc.   The output will be a plain text into a TextBox.  I am trying to make those information appear in kind of columns, therefore I am trying to separate them with tab to make it clearer.  For example, instead of having:  Ann 26 Sarah 29 Paul 45   I would like it to show as:  Ann tab 26 Sarah tab 29 Paul tab 45  Any tip on how to insert the tabs into my text? Why use static_cast(x) instead of (int)x? I've heard that the static_cast function should be preferred to C-style or simple function-style casting.  Is this true?  Why? Here is what I tried doing:  #!/bin/sh res=`df | awk 'FNR == 2 { print $5 }'` res2=$((res+0))   Here is my error:     -bash: 53%: syntax error: operand expected (error token is "%")   I Googled 'string to int bash' which showed me $((res+0)) but it doesn't work due to the % in the string (53%). How do I convert it in such a way I can do an if statement such as the one below (but that works)?  if [ "$res2" -ge 50 ] then     echo "Your disk &gt;=50% full!" fi
