As the title states, I am having trouble with entity teleporting in Minecraft. I know that I am doing it correct as it works in singleplayer, so I figured it would be a plugin that is stopping me from teleporting entities. The command I am using is /tp @e[name=o] ~ ~300 ~, and the plugins on my server are:     AsyncWorldEditInjector, WorldEdit, Installer, VoxelSniper, Skript,   CustomServerMessages, Buycraft, ColoredSigns, Vault, Multiverse-Core,   PermissionsEx, EmptyWorldGenerator, WorldGuard, Tablist, CoreProtect,   ItemRenamer, BuycraftAnnouncer, NoLeafDecay, WildSkript, ProtocolLib,   HolographicDisplays, mcMMO, VoidWorld, Essentials, ArmorStandEditor,   AsyncWorldEdit, EssentialsProtect, AuctionHouse, EssentialsSpawn,   EssentialsGeoIP, WirelessRedstone, EssentialsAntiBuild,   FakePlayersOnline, TitleManager, CraftBook, EssentialsChat   If you know how to fix this or what plugins to remove/disable please inform me. Thanks.
Recently I've been messing around with making a few minigames, and have used a few plugins to help make it easier to create and run them. However, a newer one I'm making requires me to use the /summon command in order to spawn zombies. However, no matter what I put in, I can't spawn hostile mobs. All other entities still spawn perfectly fine. Strangely, the /spawnmob command which comes with Essentials can summon hostile mobs fine. I would rather use /summon since it's more customizable though. Here's a list of plugins I have installed.

It seems that $\{e\}, \{e,s\}, \{e,rs\}, \{e,r^2s\},...,\{e,r^{n-1}s\}, \{e,r,r^2,...,r^{n-1}\}, D_n$ are always subgroups of $D_n$. Especially when $n$ is odd, these seem to be the only subgroups. But when n is even, say $n=4$, then there are also $\{e,s,r^2,r^2s\}$ and $\{e,rs,r^2,r^3s\}$. It makes me wonder, is there a general formula/algorithm for finding all subgroups of $D_n$ when $n$ is even? Let $$G_\beta(w) = e^{\beta w^2}$$  Now I get the process of applying a fourier transform (or inverse) to get a new  gaussian:  $$G_\beta(x) = G_\beta(0) e^{\frac{-x^2}{4\beta}}$$  but in doing the derivation the constant $G_\beta(0)$ never arose. I know how to calculate the constant, but where did it come from in the derivation?  edit: Fourier form used: $$\int_{-\infty}^{\infty} f(w) e^{-iwx} dw$$ A problem about wave equation Online calculators such as  (view page source) use the below formulas to get meters per degree. I understand in general how distance per degree varies depending on latitude location, but I do not understand how that translates to the below. More specifically, where do the constants, the 3 "cos" terms in each formula, and coefficients (2, 4, 6; 3, and 5) for "lat" come from?      // Set up "Constants"     m1 = 111132.92;     // latitude calculation term 1     m2 = -559.82;       // latitude calculation term 2     m3 = 1.175;         // latitude calculation term 3     m4 = -0.0023;       // latitude calculation term 4     p1 = 111412.84;     // longitude calculation term 1     p2 = -93.5;         // longitude calculation term 2     p3 = 0.118;         // longitude calculation term 3      // Calculate the length of a degree of latitude and longitude in meters     latlen = m1 + (m2 * Math.cos(2 * lat)) + (m3 * Math.cos(4 * lat)) +             (m4 * Math.cos(6 * lat));     longlen = (p1 * Math.cos(lat)) + (p2 * Math.cos(3 * lat)) +                 (p3 * Math.cos(5 * lat)); What does  signify when using Vim LatexSuite? I have a LaTeX editing environment that does some assistive stuff such as auto-indenting, closing parentheses, etc.  However, one of the things that it does is unknown to me, and is difficult to search for. If I type an empty set of braces, it replaces them with  {}&lt;++&gt;   If I type two empty sets, for example when I'm setting up a fraction \frac{}{} what I actually get is  \frac\left\{ } \right\}&lt;++&gt;}&lt;++&gt;   Is this a problem? What does &lt;++&gt; do?

I know listings is really picky about where it goes, but there must be a way to cram a listing into a footnote, right?  (This is a MWE and my tex files are a bit more complex; my actual error is Paragraph ended before \lst@next was complete. but they are hopefully related; I couldn't get this error with the MWE.) No grub menu after Ubuntu install, booting directly into Ubuntu What does 'per unit frequency' refer to? We were discussing Kirchoff's theorem on blackbody radiation in class today and the equation was: $$e_{f}= J(f,T)$$  $e_f$ was defined as power per unit area per unit frequency. What does per unit frequency refer to here? I know what per unit time means but don't understand 'per unit frequency'. How to deal with perfect separation in logistic regression? How can I display additional boot and shutdown information on the Windows 7 welcome screen? There is a small tweak, I believe it is a registry key, that allows to display additional information on the Welcome and Shutting down screens of Windows 7 (and most likely Vista, too). I have activated this tweak on one of my systems; unfortunately I forgot how I did it, and I can't seem to find the website that originally gave me that information.  Usually, the Windows 7 welcome screen will just display "Welcome" when logging in. With the tweak activated, my Welcome screen gives status information such as "Loading user settings" or "Preparing desktop". When shutting down, the default screen simply says "Shutting down". With the tweak activated, it gives additional status information such as "Stopping Windows services". This appears the same way that Windows gives information when updates are installed or configured during the startup or shutdown procedure, and I find them quite helpful in getting a feel for what task takes how long during that process.  The only setting I was able to find is the Boot log checkbox on the Boot tab of the msconfig application. However, this results in Windows displaying console logs of drivers it is loading, etc., instead of the animated Windows title. This is NOT the setting I am looking for. The "additional boot information" setting that I have activated on this system still displays the regular animated Windows logo, and only replaces the strings displayed on the blue Welcome and Shutdown screens.  Could someone direct me to the registry key (or whatever setting) that is used to get this behaviour?  Edit: Here are a few pictures of the enhanced Welcome and Shutdown screens taken with my mobile phone—they're in German though.
