Can You Use Canvas.getContext('3d')? If Yes, How?


Answer :

There is a 3D context for canvas, but it is not called "3d", but WebGL ("webgl").


WebGL should be available in the most up-to-date versions of all browsers. Use:

<!DOCTYPE html> <html>  <body>  <canvas id='c'></canvas>   <script>     var c = document.getElementById('c');     var gl = c.getContext('webgl') || c.getContext("experimental-webgl");     gl.clearColor(0,0,0.8,1);     gl.clear(gl.COLOR_BUFFER_BIT); </script> </body> </html>

how could you use that? I tried 3D before, but didn't really understand

  • if you think "real" languages are difficult, you will have a lot of trouble with WebGL. In some respects it is quite high level, in other respects it is quite low level. You should brush up on your maths(geometry) and prepare for some hard work.
  • three.js is a very appreciated library that allows you to do yet a lot of 3d without dealing with webgl directly, check it out.

It's possible to get a WebGL context, which would give you access to that API, allowing for OpenGL ES 2.0-like 3D rendering.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
