We need to implement custom software analytics to trace the usage of the application. We have a common Command base class so the idea if to trace there something that allows us to know which command has been executed.  Consider the following sample code on a WPF Window with 1 Button:  public partial class MainWindow : Window {     private readonly Command _commandName = new Command();      public MainWindow()     {         InitializeComponent();     }      private void Button_Click(object sender, RoutedEventArgs e)     {         _commandName.Execute();     } }  public class Command {     public void Execute()     {         MessageBox.Show(this.GetCommandName());         // ....     }      private string GetCommandName()     {         string commandName = null;          MethodBase method = new StackTrace(new StackFrame(2)).GetFrame(0).GetMethod();         Type callingType = method.DeclaringType;          if (callingType != null)         {             IList&lt;FieldInfo&gt; variables = callingType.GetFields(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.GetField | BindingFlags.Instance).Where(f =&gt; f.FieldType == typeof(Command)).ToList();              if (variables.Count == 1)             {                 commandName = variables[0].Name;             }         }          return commandName;     } }   This code will show the variable name but only if there is one Command variable on the calling type. Is there a way of getting the calling variable name directly without going thru reflection?  The output of this code is (and should be) _commandName not Button_Click.
When logging in C#, how can I learn the name of the method that called the current method? I know all about System.Reflection.MethodBase.GetCurrentMethod(), but I want to go one step beneath this in the stack trace. I've considered parsing the stack trace, but I am hoping to find a cleaner more explicit way, something like Assembly.GetCallingAssembly() but for methods.
Why do we need a waveguide in a microwave oven? Why do we need a waveguide to move microwave power from the magnetron to the microwave cavity? Can't we just push magnetron antenna into the cavity? Why does it have to go through a waveguide? How can I start up an application with a pre-defined window size and position? I'm wondering is there any way to achieve the affect of the Ctrl-Alt-Keypad shortcuts in Unity using terminal commands instead? I want a command that sets a gui window to half the size of the screen, either left or right aligned.  By way of background, I'm writing a script that runs after log in. It uses Zenity to ask whether or not I want to open my development environment (GVim and IPython side-by-side). I have been trying to achieve two equal-sized windows for these programmes by using set lines= columns= in my .gvimrc and c.IPythonWidget.width = and c.IPythonWidget.height = in my ipython_qtconsole_config.py. However, there are problems associated with this approach. Can wizards create their own spells? In the Harry Potter series, are wizards capable of creating their own spells, or are they limited to the spells that they're taught/learn?  I seem to remember something about Snape creating sectumsempra, but I'm not sure if that really is the case. How do you import CA certificates onto an Android phone? I want to connect to my University's wireless using my Nexus One. When I go to "Add Wi-Fi network" in Wireless Settings I fill in the Network SSID and select 802.1x Enterprise for the security and fill everything out.  The problem is that our university's wireless uses Thawte Premium Server CA certificate for certification.  When I click the drop down list for CA certificate I get nothing in the list (just N/A)  Now I have the certificate (Thawte Premium Server CA.pem) and have moved it to my SD card, but it doesn't look like Android automatically detects it.  Where should I put the certificate so that the Android wireless manager recognizes it. In other words, how can I import a CA certificate so that Android recognizes that it is on the phone and displays it in the CA Certificate drop down list.  Thanks for any help,  Tomek  P.S. My phone is not rooted  EDIT: After doing some research it looks like you are able to install certificates by going to your phone's settings > Location &amp; Security > Install from SD card  Unfortunately it looks like the only accepted file extension is .p12. It does not look like there is a way to import .cer or .pem files (which are the only two files that come with the Thawte certificates) at this moment.  It does look like you can use a converter to convert your .cer or .pem files to .p12, however a key file is needed.    I do not know where to get this key file for the Thawte certificates. I have a vps using Ubuntu 12.04 LTS and I my host corrupted my vps so now it won't boot up. When it boots up it says:  Booting from Hard Disk... error: file not found. grub rescue&gt;   How can I fix/repair this? Closed form for $\int_0^1\log\log\left(\frac{1}{x}+\sqrt{\frac{1}{x^2}-1}\right)\mathrm dx$ Why don't planets have Circular orbits? Prove that the expression is a perfect square Let $m$ be a natural number. Define $f(m) = m + \lfloor\sqrt{m}\rfloor$. Prove that at least one of the number among $m, f(m), f^2(m), \ldots$ is a perfect square. Here $f^k(m)$ denotes the composition of $f$ over itself $k$ times.  I tried the question, but the greatest integer along with square root is creating trouble. Q: "Do you have any juice?"   A: "Yes, there's some in the fridge."   Sounds perfectly fine to me, but:     Q: "Do you have any towels?"   A: "Yes, there's some in the closet."   Does not.  I asked for towels - plural - so wouldn't "Yes, there're some in the closet," in which there are is turned into a contraction be the correct way to say it?  Spellcheck, however, doesn't like "there're", and I think I'm the only person I've ever heard use the word "there're".  Even folks who I know say "there are" shorten it to "there's" when possible.  Am I saying it wrong, or are both forms acceptable? wp_customize_image_control default value Given two separate annulus with centers $[C_1,C_2]$ and their corresponding radii being $[R_1,r_1]$ and $[R_2,r_2]$ respectively, larger radius being $R$. There are methods to look at whether they are overlapping or not. If they overlap how to find the overlapping area.

I have been trying to make a short clip of a bullet hitting a wine glass with wine in it, but I keep running into the same problem with the add-on. Every time I have used it the result has left me with at least a partial box being generated as several of the fractured pieces.  I have tried subdividing and/or adding a sub-surf modifier but the result only changes where the large distorted fragments end up. I have been having trouble with this for quite some time and I would greatly appreciate any help. What expression would be the opposite of "Deal Breaker"? I understand that "Deal breaker" is an expression used for a feature/characteristic that would make one not go for a deal (or terminate a contract), even if the deal's other features are great.  What expression would be the opposite of "Deal Breaker"? I'm looking for an existing expression that would describe a feature that would make one go for the deal, even if there are other not so great characteristics.  The expression could fill the sentence below:     I know this phone carrier has higher rates and everything, but if   they are offering free iPhone to us if we switch, that would be a &lt;expression   here&gt;! We would totally go for it. A childish question (literally) -    My 8 year old asked me this morning: "Dad, what does 'physical' mean?" - and I found myself at loss for an ordinary language answer.   Every answer I could come up with ended up sounding like a definition of empiricism: "physical things are those things that can be observed", "physical means something that can be measured", "whatever can be verified and tested", etc....   Claiming that things that are physical are those things which are material or things that are described by physics seems circular.   Google:     phys·i·cal   ˈfizik(ə)l/   adjective   1.   relating to the body as opposed to the mind.   "a whole range of physical and mental challenges"   synonyms:   bodily, corporeal, corporal, somatic; More   2.   relating to things perceived through the senses as opposed to the mind; tangible or concrete.   "pleasant physical environments"   synonyms:   material, concrete, tangible, palpable, solid, substantial, real, actual, visible   "the physical universe"   And various dictionaries (here Merriam-Webster):      Definition of physical   1   a :  of or relating to natural science   b (1) :  of or relating to physics (2) :  characterized or produced by the forces and operations of physics   2   a :  having material existence :  perceptible especially through the senses and subject to the laws of nature   everything physical is measurable by weight, motion, and resistance — Thomas De Quincey   b :  of or relating to material things     lead to similar definitions.   How can one define "physical" in ordinary language terms? Is there a way of defining "physical" that doesn't presuppose empiricism? What is the rationalist definition of 'physical'?   Is there a definition that doesn't commit to either dualism or empiricism or to any epistemology? Does Thanos' plan apply to higher order beings?

Is the $ L^{p}$$[0,1]$ norm continuous in p? I ran into the following problem when I was doing my homework, and I have no thoughts on where I should start with:  (1) If $f\in L^{2}$, show that $\displaystyle \lim_{p \rightarrow 1^{+}}\int_{[0,1]}|f|^{p}=\int_{[0,1]}|f|$  (2) If $0&lt;p$, show that $\displaystyle \lim_{q\rightarrow p^{-}}||f||_{q}=||f||_{p}$  My first thought was Generalized LDCT, but it didn't seem to work. I also made some other attempts but none of them were successful... Can anybody give me some hints on how I should look at this question?  Also, I know if $p\rightarrow\infty$ then $||f||_{p}\rightarrow||f||_{\infty}$ on $[0,1]$, but does similar continuity in p holds for other $L^{p}[0,1]$ norms in general?  Thank you!  Edit:   Sorry if I did not make it clear enough in the question. All $L^{p}$ refers to $L^p[0,1]$.  The first question is found  (thanks to t.b.), but the second question remains, mainly because $f$ is not guaranteed to be in any $L^{p}$. Suppose the default shell for my account is zsh but I opened the terminal and fired up bash and executed a script named prac002.sh, which shell interpreter would be used to execute the script, zsh or bash?
