Making a C++ callable .lib or .dll file from a Mathematica notebook
Does Mathematica have a "MATLAB Builder" equivalent?
Highlight whole TreeViewItem line in WPF Now that I know , I was wondering how I can restart the phone or turn it off.  The lock button is completely unresponsive and holding it down does nothing. Are there any workarounds besides replacing the button? When does the set enter set theory? I'm looking to generate a set of 5 random variables and enforce a dependence structure between them and onto a dependent variable $Y$.  I understand how to generate correlated random variables for multivariate normal, but not when mixing different types.  Below is a little more than I need, but I'm hoping someone can give me a general way of solving this problem...   $X_1$ and $X_2$ need to be highly correlated Bernoulli variables.  $X_3$ needs to take one of 5 categorical values, call them "A"..."E".  $X_4$ needs to be normal, and negatively correlated with $X_1$, $X_2$.  $X_5$ needs to approximate test scores from $0$ to $100$ with a high skew, so gamma probably.  $X_5$ needs to be positively correlated with $X_1$, $X_2$, $X_4$.   Each of these variables must impact a "success/occurrence" Bernoulli distributed variable $Y$.  How would I begin?  I would like to enforce correlation both between the values of $X$, and also between each $X$ and $Y$.  (The categorical correlations seem particularly confusing to me.) Software for measuring internet traffic? I'm interested in finding a free piece of software for Windows XP &amp; 7 that allows us to measure both incoming and outgoing internet traffic, but not traffic between users of the local network.  I live in a shared household with three others, and we're interested to see which of us is using the largest amount of our monthly internet quota. We're all happy to install the necessary software.  Any suggestions? List of interesting math videos / documentaries This is an offshoot of the question on . I have listed a few videos/documentaries I have seen. I would appreciate if people could add on to this list.  $1.$ Story of maths      $2.$ Dangerous Knowledge    $3.$   $4.$   $5.$ When asking about , people sometimes refer to the strict aliasing rule. What are they talking about? python multiprocessing on windows, if __name__ == "__main__" When NASA sends astronauts to space, they have to wear uncomfortable suits. Why aren't the humans in Star Wars spacecraft doing the same thing? What technology do they have on board that remove this need? I have Windows 8 Pro activated with kms. when I open windows store, it doesn't show "win8.1 available". clicking on ms-windows-store:WindowsUpgrade just brings me to windows store main screen  slmgr /dli shows volume_kmsclient channel  I can upgrade it to WMC. Laptop is W8Pro WMC and update is available, it's retail channel  Is W8 for KMS clients delayed or what? Can a third type of electrical charge exist? Upon reading my book on physics, it mentions that there are only two discovered types of electric charges. I wonder if there could be a third type of elusive charge, and what type of effects could it have upon matter or similarly? Is it possible to use a hyphen in a listing (in a sentence) for abbreviation, even if the compound word consists of two separate words root of an odd degree polynomial Im asked to prove that a polynomial of an odd degree has a root. Im going to use IVT to prove this, but I'm wondering if I can use the assumption that an odd degree polynomial has either two cases:  $$ \lim_{x\to\infty}h(x)=+\infty \\ \lim_{x\to-\infty}h(x)=-\infty \\ $$ $$and$$ $$ \lim_{x\to\infty}h(x)=-\infty \\ \lim_{x\to-\infty}h(x)=+\infty \\ $$ Then by this there exists numbers $a,b$ such that $$ h(a)&lt;0&lt;h(b) $$ $$or$$ $$ h(b)&lt;0&lt;h(a) $$ Which I think would prove that odd degreed $h(x)$ has at least a root. Or is there a more convincing way to show that there are numbers in $h(X)$ greater than zero and less than zero?  edit: (sorry about the bad limit notation) How best to determine if an argument is not sent to the JavaScript function I have now seen 2 methods for determining if an argument has been passed to a JavaScript function. I'm wondering if one method is better than the other or if one is just bad to use?   function Test(argument1, argument2) {       if (Test.arguments.length == 1) argument2 = 'blah';        alert(argument2);  }   Test('test');   Or   function Test(argument1, argument2) {       argument2 = argument2 || 'blah';        alert(argument2);  }   Test('test');   As far as I can tell, they both result in the same thing, but I've only used the first one before in production.  Another Option as mentioned by :  function Test(argument1, argument2) {     if(argument2 === null) {         argument2 = 'blah';     }      alert(argument2); }   As per Juan's comment, it would be better to change Tom's suggestion to:  function Test(argument1, argument2) {     if(argument2 === undefined) {         argument2 = 'blah';     }      alert(argument2); } No error message if the URL is very long I entered a URL with a very long parameter on Stack Exchange.  I have type this url    It shows a blank screen , does not shown any messages.    We need to show a “Page Not Found” message, same as what you did on other Stack Exchange pages. Let $a,b,c\in \Bbb R^+$ such that $(1+a+b+c)(1+\frac{1}{a}+\frac{1}{b}+\frac{1}{c})=16$. Find $(a+b+c)$ As we all know, going near a black hole (Gargantua in this case) slows down time, according to the theory of relativity.  So when Cooper comes out of the black hole, after spending a fair bit of time there, shouldn't he be much older than Brand who hasn't gone inside Gargantua? What can I do when getting "We are no longer accepting questions/answers from this account"? Where is a good place to learn classical optics for high school competitions? I need to learn basic optics for a high school academic competition. Does anyone know any good places, preferably free and online, to learn the basics of optics, like lenses, angles of incidence, etc.? I can't seem to find an MIT OpenCourseWare course addressing the issue. I'm new to inequalities in mathematical induction and don't know how to proceed further. So far I was able to do this:  $V(1): 1≤1 \text{  true}$  $V(n): n!≤((n+1)/2)^n$  $V(n+1): (n+1)!≤((n+2)/2)^{(n+1)}$  and I've got : $(((n+1)/2)^n)\cdot(n+1)≤((n+2)/2)^{(n+1)}$ $((n+1)^n)n(n+1)≤((n+2)^n)((n/2)+1)$
