I've puchased a big interior scene from a 3d marketplace.   To optimize it in Unity (using Occlusion culling), I need to break the meshes into pieces, without modifying the structure.   Is there any blender command to do this?
I want to make the teeth a separate child object from the mouth. I want to know the best way to do this.   I have tried going into edit mode with Tab and trying to select all the vertices but that doesn't move the teeth. Is there an easy way to select just that part and make it a separate child mesh to the rest of the mouth?
How many ways are there to distribute 5 distinguishable balls between 3 kids such that each of them gets at least one ball?   My approach is $ \binom{5}{3} 3! $ + $ \binom{2}{2} \binom{3}{2}2!$ which is equal to $66$? Making data points different sizes based on data using QGIS? I am trying to plot sales data on a map using QGIS. I will add the disclaimer that I am a rookie at using the program. I added the different sales types by adding delimited text layers (utf16). The data included Longitude, Latitude, and Amount. I want to make the dots on the map scale with the value of the sale. Ive had no luck with trying to use Simple Marker->Data defined properties-> size and writing case functions. Some data points show up at different sizes while others show up at all data points. Here are my functions under different simple markers:   CASE WHEN Amount &lt;= 10000 THEN '.2' END CASE WHEN 10000 &lt; Amount &lt; 75000 THEN '.4' END CASE WHEN 75000 &lt; Amount &lt;= 250000 THEN '.6' END CASE WHEN Amount &gt;= 250000 THEN '1' END   The majority of my data set falls into the 10-75k range. However the .4 and .6 size circles show up at every data point on the map, while the .2 and 1 sizes only show up where the data specifies (along with the .4 and .6 sizes). At this point I am trying to figure out what is wrong with the equations, however I am stuck.   Is there a better way to go about this or am I just simply messing up the equations?   I wish I could share my whole map with you but it is looking great. I went with U/Joseph 's solution and here is an excerpt of the results for those interested. I have a site which is only for US/Canada/UK visitors. I don't want to make it visible to other visitors.  I tried to put IP ranges in .htaccess (Deny IP) but it does not work for me. May be I have inaccurate IP lists or I am doing something wrong. Are mirror lenses good for wildlife photography in daylight? I've recently seen these Rokinon/Opteka mirror lens with whooping focal length (like 500mm, 600mm, 800mm, 1000mm) at a cheap price. And I have seen some of their same pictures in Flickr and vendor sites. But the only thing is that they usually starts from smaller aperture (f/5.6 and upwards)   Now what I was wondering, as they are cheap with quite good IQ - are they good for any bird photography or wild life photography in proper daylight? Calculating the eigenvalues of a matrix How to find the eigenvalues of $$\begin{bmatrix} 0 &amp; 1   &amp;   &amp;  &amp;\\ k &amp; 0   &amp; 2 &amp;  &amp;\\   &amp; k-1 &amp; 0 &amp; 3 &amp;\\   &amp;     &amp;\ddots&amp;\ddots&amp;\ddots\\   &amp;     &amp;      &amp;2 &amp; 0 &amp;k \\   &amp;     &amp;      &amp; &amp; 1 &amp;0 \end{bmatrix}$$ I tried recurrence equation, but it doesn't work to find the characteristic polynomial. Any hint or solution are welcomed, thanks for your help!  PS:The missing parts are all zeroes. I am trying to balance underbraces in the equation below, how can I ensure that both underbraces at the same depth?  \begin{equation} y = \underbrace{ \left [ x^2 + r^2 (a^2+\frac{a^{0.3}}{b}) \right]}_\text{growth rate} \times  \underbrace{ C_0}_\text{initial} \end{equation} I have a problem when I try to start a Workflow 2013 in SharePoint Server 2013.

I’ve set a WF Manager service account named “wfservice” (this account is a local admin and has the sysadmin permissions in SQL Server), and I published the workflow and tested it using the account “wfuser”. Both accounts have full control permissions in the web app and are site owners, for testing WF 2013 purposes.  I’ve already done the DNS flush, as mentioned in Andrew Connell’s article, and I’m still getting an Unauthorized exception in the Item Workflow Status.  Anyone knows what’s going on? Which permissions do I need to configure? List of freely available physics books I'm trying to amass a list of physics books with open-source licenses, like Creative Commons, GPL, etc. The books can be about a particular field in physics or about physics  in general.  What are some freely available great physics books on the Internet? edit: I'm aware that there are tons of freely available lecture notes online. Still, it'd be nice to be able to know the best available free resources around.  As a starter:         Table of contents sorted by field (in alphabetical order): Family of irreducible polynomials How can I disable creepers' block damage on my Minecraft server? Please note that these are NOT acceptable solutions:   Completely disabling monsters (peaceful mode) Completely removing creepers Completely disabling explosions (TNT + Creepers) Disabling creeper explosions   More exactly, I want the creepers to be able to spawn and explode, but without doing their terrain damage (they should still be doing health damage to the players).  I'm fine with the use of mods but I'd prefer a built-in solution if possible. Writing comments in QGIS Graphical Modeler I want to explain my model step by step so anyone can easely understand what's going on. So, is it possible to write comments in the QGIS's Graphical Modeler? I am looking for a book about "advanced" classical mechanics. By advanced I mean a book considering directly Lagrangian and Hamiltonian formulation, and also providing a firm basis in the geometrical consideration related to these to formalism (like tangent bundle, cotangent bundle, 1-form, 2-form, etc.).  I have , but I would like to go into more details about the [symplectic] geometrical and mathematical foundations of classical mechanics.  Additional note: A chapter about relativistic Hamiltonian dynamics would be a good thing. As the title says. I use, among other things, the following in my lstset:  framerule=1pt, frame=tblr   Some places a page break happens in the middle of my \lstlisting. Fine. But sometimes the whole code of the listing appears on one page, but the bottom frame appears on the top of the next page!    I know that I can float a particular listing, but I have a long document with many listings, and I don't want to float all of them; Most of them also need to be exactly where they are declared. That they are broken over a page doesn't bother me that much.  Is there something that can stop this from happening, without me needing to adjust each individual listing?   had the same problem, but fixed it by removing spaces in front of keywords in a custom language definition. I too have a custom language definition, but his solution doesn't help me. I managed to recreate the situation without a custom language.  Edit and MWE  I managed to reproduce it in a minimal working example. 's a pastebin, if that's helpfull.  \documentclass[UKenglish,a4paper,11pt]{report} \usepackage{babel}  %% Adjustments \addtolength{\topmargin}{-1\baselineskip} \addtolength{\textheight}{4\baselineskip} \pretolerance = 2000 \tolerance = 5000   \hbadness = \tolerance  %% Smaller font \usepackage{mathptmx}  %% LISTINGS \usepackage[final]{listings} \lstset{     xleftmargin=1.5em,     framexleftmargin=1em,     framextopmargin=0.5ex, %%  THE FRAME:     framerule=1pt,     frame=tblr }  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  \usepackage{lipsum}     % for demo \begin{document} \subsubsection{Lorem}   % some fiddling to get the "wrong spacing just right": \lipsum[1-3] \subsubsection{Ipsum}  \lipsum[1] and then some text  \begin{lstlisting} Here is a listing with three lines of code; The bottom border is placed on the next page! \end{lstlisting}  Can you believe it..?! \end{document}   This MWE is rather long. My document inputs most of the listings stuff from files written by others, so I'm not sure what all of it does. If anyone sees some lines that they are sure is irrelevant, feel free to take it out of the MWE.  "Fun fact"  An equally silly situation occurs if you remove \usepackage{mathptmx}: The whole code listing will then appear on the new page, except for the top frame which is left on the bottom of the first page! I am Indian passport holder living in Hungary for 4 years and I have been issued a Temporary residence permit (EU Schengen).  Can I go to visit Dublin without any visa, or do I need to apply for a UK visa? I know Ireland still in Schengen but part of United Kingdom. Prove $\sum_{k = 0}^{n}(-1)^{n - k} \binom{n}{k} \cdot k^n = n!$ and $\sum_{k = 0}^{n}(-1)^{n - k} \binom{n}{k} \cdot k^m = 0$ Prove $$\sum_{k = 0}^{n}(-1)^{n - k} \binom{n}{k} \cdot k^n = n! \qquad\text{and}\qquad \sum_{k = 0}^{n}(-1)^{n - k} \binom{n}{k} \cdot k^m = 0,$$ where $m \in \{0, 1, 2, \cdots, n - 1\}$.  To be honest, I tried to use some combinatorial ideas but was not able to see interconnections. Also, I had an idea to prove it using induction but failed to do that either. Help will be much appreciated! I just got stuck and don't see any continuation of solution for this problem Why didn't Star Trek TOS have better medical equipment for Vulcans? In  when Ambassador Sarek became critically ill, why didn't they send him home or send for a Vulcan medical expert? Since they were hosting many prominent political figures from many races, it seems strange that they did not have much medical support for a race so common as Vulcans (who are part of the Federation). Resizing an iframe based on content I am working on an iGoogle-like application. Content from other applications (on other domains) is shown using iframes.   How do I resize the iframes to fit the height of the iframes' content?  I've tried to decipher the javascript Google uses but it's obfuscated, and searching the web has been fruitless so far.  Update: Please note that content is loaded from other domains, so the  applies. Create a .desktop file that opens and execute a command in a terminal I would like to know how to write the Exec command of a .desktop file to open a new terminal and execute a shell script in it. The shell script is working and accessible by all users. When launching the script from the terminal everything works, but it doesn't when trying to launch the script from a .desktop file.  Here are some combinations I have already tried:  Exec=gnome-terminal -x sh -c 'echo hello' Exec=sh -c 'gnome-terminal echo hello' Exec=sh -c 'echo hello' Exec=echo hello   The .desktop terminal option is set to true. What is the word for when someone is overly nice and actually isn't nice at all? What is the word for when someone is overly nice and actually isn't nice at all because of the unnecessary added information/comments? For example, they will say things like "Your hair looks so good that wayyyy omg you should do it that way ALL the time! Looks way better than how you usually do it." And the word I'm looking for is not passive aggressive and it is not sarcasm. There is a word for these types of people. What is it? These people think they're being kind but actually blunt and rude. Another example would be for someone to say "hey you're beautiful, but maybe if you didn't wear harsh makeup you would look better" and they intend to sound like they're being nice when you know they don't like you and are saying in out of spite. On-screen keyboard popping up whenever I touch screen I'm in 17.10. Whenever I touch the screen, whether to change windows/apps, scroll within a browser, or press a button, the stupid little keyboard pops up in the bottom left corner.  I have never left Screen Keyboard enabled in Universal Access, but if I toggle it on, that's the same keyboard popping up in the bottom left corner.    In this screenshot, I'm simply touching the screen in a full-screen youtube video. You can see the menu pop up on the right, under the point where I'm touching.  I don't have a before pic, but it was similar look/color keyboard, but it was smaller, maybe half as wide, and only in the bottom left section of the screen, as opposed to stretching across the entire width. This change from little left-hand keyboard to full-width keyboard happened after following @pomsky 's advice below.    This is a . You can mark yourself affected by it to hopefully increase its received attention.
