Best Lightweight Web Server (only Static Content) For Windows

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...

Apache Is Not Running From XAMPP Control Panel ( Error: Apache Shutdown Unexpectedly. This May Be Due To A Blocked Port)

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...

Click Event For WPF Image

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...

Braket Notation In LaTeX

Image
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.

Android Context.getResources.updateConfiguration() Deprecated

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...
