Freestyle with multiple objects I have several objects that intersect each other:   I would like to draw lines on the silhouette and key details with Freestyle, however Blender does detect intersections between objects and gives a very strange result:   What I'm trying to make is something like this:   Note: This is just an example, what I'm trying to do has about 10 highly detailed objects which intersect each other, so manually combining them is not possible.  Is it possible to make Freestyle detect edges at face intersections? If not, is there a simple way of combining the objects to create a single object with the outer faces of all the objects? How to use unicode characters in Windows command line? We have a project in Team Foundation Server (TFS) that has a non-English character (š) in it. When trying to script a few build-related things we've stumbled upon a problem - we can't pass the š letter to the command-line tools. The command prompt or what not else messes it up, and the tf.exe utility can't find the specified project.  I've tried different formats for the .bat file (ANSI, UTF-8 with and without ) as well as scripting it in JavaScript (which is Unicode inherently) - but no luck. How do I execute a program and pass it a Unicode command line? Is it possible to bring built-in lightning components into aura component? I have a form that needs to let the user select 3 out of 5 products, something similar to Order > Add Product (Modal). I was wondering if there was a way to bring that piece into my component (markup) and add some sort of filter that only shows the products I want to show.  What I found so far:  &lt;lightning:listView objectApiName="Products2" listName="productsView" showActionBar="true" enableInlineEdit="true" showRowLevelActions="true"/&gt;   But Product2 is not supported for that component.  also these from browser inspector:  forceMultiAddUsingLVM forceListViewManager   These are data-aura-class attributes when rendered.  I'm looking for directions here. Thanks in advance. Likelihood Ratio Test for Exponential Distribution with a Limited Parameter Space I know that I can append &amp; to a command to run the process in the background.   I'm SSH'ing into an Ubuntu 12.04 box and running a python program with $python program.py &amp; -- but when I go to close the terminal window I get a message saying that closing the terminal will kill the running process.   Why is this? I am using the ampersand to run the process in the background. How can I get it to run regardless of if I am SSH'ed in? I have a computer with Windows XP installed.  My user does not have a password.  When Windows starts, it goes to the login screen. Because my user has no password, is there any way to bypass this screen, and log in automatically? $n\ge 8\,\Rightarrow\, n = 3j + 5k\ $ for $\,j,k,n\in \Bbb N$ I'm new to Math Induction, I don't know how it goes from $𝑘 + 1 = 3𝑥 + 5𝑦 + 1$ into $5𝑦 = 5𝑦 − 5 + 5.$  I'm trying to prove that:   Any whole number of at least 8 cents can be obtained using coins of 3 and 5 cents  Assume: There is a number $𝑘$ for which there are $𝑥$ and $𝑦$ such that $𝑘 = 3𝑥 + 5𝑦$  Here's my working:  $𝑘 = 3𝑥 + 5𝑦$  Therefore $𝑘 + 1 = 3𝑥 + 5𝑦 + 1$  $5𝑦 = 5𝑦 − 5 + 5$  $5𝑦 = 5 𝑦 − 1 + 5$  $𝑘 + 1 = 3𝑥 + 5𝑦 + 1$  $𝑘 + 1 = 3𝑥 + 5(𝑦 − 1) + 5 + 1$  $𝑘 + 1 = 3𝑥 + 5(𝑦 − 1) + 6$  $𝑘 + 1 = 3(𝑥 + 2) + 5(𝑦 − 1)$  $𝒌 + 𝟏 = 𝟑𝒙' + 𝟓𝒚'$ There is a bar of chocolate of size $N$ x $M$. Little square $(x, y)$ is poisoned. There are 2 players taking turns. In each move they can cut the bar along any of the horizontal or vertical lines, then the part which does not contain $(x, y)$ is being eaten. The player who is left only with square $(x, y)$ loses (beacause it is poisoned). Which player has the winning strategy? I guess that this game is equivalent to game of Nim due to Sprauge-Grundy theorem, but I don't know how. When you are trying to say that something is automatically filled in, you use the word autofill, or if you were using past tense, autofilled.    I see 3 main ways that people use it:   auto fill / auto filled  auto-fill / auto-filled autofill / autofilled   Note: this also applies to pre fill, pre-fill, and prefill as well.  Which way is the most preferred spelling? Sharing alignment between equations in two different items In the following minimal example, I have two equations inside an itemize environment, with an item per equations. Each equation is defined in its own equation environment.    \documentclass{article} \usepackage{amstext}  \begin{document}  \begin{itemize}  \item Lorem ipsum dolor sit amet, consectetur adipiscing elit:   \begin{equation}     f(x) = \left\{     \begin{array}{l l}       1 &amp; \text{ nisl justo, hendrerit} \\       0 &amp; \text{ sagittis condimentum}\\     \end{array} \right.  \end{equation}   \item Duis magna nunc, ultrices at fringilla non, feugiat sed massa:   \begin{equation}     g(x) = \left\{     \begin{array}{l l}       -1 &amp; \text{ fermentum fringilla mauris eget} \\       0 &amp; \text{ gravida ipsum vitae}\\     \end{array} \right.  \end{equation} \end{itemize}  \end{document}   However, each equation has its own alignment, giving the following result:    It would be nice (I think) if both equations could be aligned in the same way, something like this:    Is this possible?   Note: it would be nice if the solution could be also applied to equations in different paragraphs.    UPDATE:   presented a very nice solution, which is currently the most upvoted, but it does not work quite well:  \documentclass{article} \usepackage{amsmath} \begin{document}  This is a list.  \begin{itemize}    \item First item.   \begin{align*}   f(x) &amp;= \begin{cases} 0 &amp; \text{now} \\ 1 &amp; \text{then} \end{cases}   \intertext{\item Second item.}   g(x) &amp;= \begin{cases} 0 &amp; \text{here and there}  \\ -1 &amp; \text{to and fro} \end{cases}   \end{align*}  \end{itemize}  After the list. \end{document}     Can you see? "now" and "then" are not aligned to "here and there" and "to and fro". Can we solve this? :) Running JAR file on Windows I have a JAR file named helloworld.jar. In order to run it, I'm executing the following command in a command-line window:  java -jar helloworld.jar   This works fine, but how do I execute it with double-click instead? Do I need to install any software? Math people:  The title is the question. I am convinced that uncountable sets exist, thanks to Cantor's diagonal proof.  It is not intuitively clear to me that uncountable ordinals or cardinals should exist.  What axioms of set theory are needed to accept their existence?  I think I have read here that the Axiom of Choice is not necessary.  I am reluctant to accept as "true" any theorems that rely on the Axiom of Choice.  EDIT: This question may be a duplicate: I just found  .  I apologize if this is so. UK Visa has been refused for false document Can Mage Hand be used in combat to grab something from an opponent?  For example, one could grab a bow out of their hands or the arrows from a quiver, or try to push them out of a tree, etc.  Mage Hand can carry up to 10 pounds, but what is its ability to interact in situations like these? why would curl and wget result in a 403 forbidden? I've recently started maintaining someone else's JavaScript code. I'm fixing bugs, adding features and also trying to tidy up the code and make it more consistent.  The previous developer used two ways of declaring functions and I can't work out if there is a reason behind it or not.  The two ways are:  var functionOne = function() {     // Some code };     function functionTwo() {     // Some code }   What are the reasons for using these two different methods and what are the pros and cons of each? Is there anything that can be done with one method that can't be done with the other? DSolve gets stuck on system of differential equations with unassigned variable - but IMHO there has to be a simpler solution.
