Example: Diamond inheritance The "diamond problem" ( sometimes referred to as the "Deadly Diamond of Death" ) is an ambiguity that arises when two classes B and C inherit from A , and class D inherits from both B and C If there is a method in A that B and C have overridden , and D does not override it , then which class of the method does D inherit : that of B , or that of C ?

Answer : You can use Python as a quick way to host static content. On Windows, there are many options for running Python, I've personally used CygWin and ActivePython. To use Python as a simple HTTP server just change your working directory to the folder with your static content and type python -m SimpleHTTPServer 8000 , everything in the directory will be available at http:/localhost:8000/ Python 3 To do this with Python, 3.4.1 (and probably other versions of Python 3), use the http.server module: python -m http.server <PORT> # or possibly: python3 -m http.server <PORT> # example: python -m http.server 8080 On Windows: py -m http.server <PORT> Have a look at mongoose: single executable very small memory footprint allows multiple worker threads easy to install as service configurable with a configuration file if required The smallest one I know is lighttpd. Security, speed, compliance, and flexibility -- all of these describe ligh

Answer : There are many possible answers for this problem. The most common and most likely is that you're running another program which is blocking port 80 or 443. If you've installed Skype, then you've found your problem! Change apache's port settings to 81 and apache will work. There's a good tutorial on that To check this you can open up your command line by clicking the start menu, and typing 'cmd', and enter the command netstat -nab this wil return a list of programs that will vaguely resemble this pattern [someprogram.exe] UDP [fe80::numbers:numbers:numbers:numbers%numbers]:portnumber You need to find a line (or lines) ending in :80 and terminate them in order to start apache. If there is no line ending in :80, there are more things you can do. First, navigate to xampp's directory (default is c:\xampp) and double click apache_start.bat. This will open up a comand line and return more detailed errors about why apache can

Answer : Just add a MouseDown (or MouseLeftButtonDown as suggested) event to your image like so <Image x:Name=aPicture Source="mypic.jpg" MouseDown="aPicture_MouseDown"/> // or <Image x:Name=aPicture Source="mypic.jpg" MouseLeftButtonDown="aPicture_MouseDown"/> which should add this to your code behind private void aPicture_MouseDown(object sender, MouseEventArgs e) { //do something here } In WPF each control has its default template (how it looks) but you can easily change these templates and make controls look like you want. This makes it easier to pick control by its functionality and make it look like you want. In your case you want Click so you choose Button and change its Template <Window ...> <Window.Resources> <Style TargetType="{x:Type Button}" x:Key="ImageButtonStyle"> <Setter Property="Template"> <Setter.Value&g

Answer : There is the physics package: \documentclass{article} \usepackage{physics} \begin{document} $\bra{\Psi}\ket{\Psi}$ $\expval{A}{\Psi}$ \end{document} It offers many other goodies for typsetting physics things. Details can be found in the manul ( texdoc physics from command prompt/terminal). Use \braket{0|0} : \documentclass{standalone} \usepackage{braket} \begin{document} $\braket{0|0}$ \end{document} A solution using the mathtools package: \documentclass{article} \usepackage{mathtools} \DeclarePairedDelimiter\bra{\langle}{\rvert} \DeclarePairedDelimiter\ket{\lvert}{\rangle} \DeclarePairedDelimiterX\braket[2]{\langle}{\rangle}{#1 \delimsize\vert #2} \begin{document} \begin{align*} \bra{a} &= \bra*{\frac{a}{1}} \\ \ket{a} &= \ket*{\frac{a}{1}} \\ \braket{a}{b} &= \braket*{\frac{a}{1}}{\frac{b}{1}} \end{align*} \end{document} Notice that the starred versions of the macros scale automatically.

Answer : Inspired by Calligraphy, I ended up creating a context wrapper. In my case, I need to overwrite system language to provide my app users with the option of changing app language but this can be customized with any logic that you need to implement. import android.annotation.TargetApi; import android.content.Context; import android.content.ContextWrapper; import android.content.res.Configuration; import android.os.Build; import java.util.Locale; public class MyContextWrapper extends ContextWrapper { public MyContextWrapper(Context base) { super(base); } @SuppressWarnings("deprecation") public static ContextWrapper wrap(Context context, String language) { Configuration config = context.getResources().getConfiguration(); Locale sysLocale = null; if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N) { sysLocale = getSystemLocale(config); } else { sysL
