HTML5 Canvas Element Tutorial. Published on October 30th 2010 by Eric Rowell The HTML5 Canvas element is an HTML tag similar to the <div>, <a>, or <table> tag, with the exception that its contents are rendered with JavaScript. In order to leverage the HTML5 Canvas, we'll need to place the canvas tag somewhere inside the HTML document, access the canvas tag with JavaScript, create a context, and then utilize the HTML5 Canvas API to draw visualizations.
When using canvas, it's important to understand the difference between the canvas element and the canvas context, as often times people get these confused. The canvas element is the actual DOM node that's embedded in the HTML page. The canvas context is an object with properties and methods that you can use to render graphics inside the canvas element.
The context can be 2d or webgl (3d). HCT Pro Tip Each canvas element can only have one context. HTML5 Canvas Template Author Bio Eric Rowell (@ericdrowell) Submit an Article Hi there!

TIOBE Index for January 2016 January Headline: Java is TIOBE's Programming Language of 2015! Java has won the TIOBE Index programming language award of the year. This is because Java has the largest increase in popularity in one year time (+5.94%). Java leaves runner ups Visual Basic.NET (+1.51%) and Python (+1.24%) far behind. At first sight, it might seem surprising that an old language like Java wins this award.
Especially if you take into consideration that Java won the same award exactly 10 years ago. On second thought, Java is currently number one in the enterprise back-end market and number one in the still growing mobile application development market (Android). Java's rise goes hand in hand with Objective-C's decline (-5.88%). So what is the outlook for 2016? The TIOBE Programming Community index is an indicator of the popularity of programming languages.

PHP-QAT: Quality Assurance Team. The Go Programming Language. Comparison of Scriptol, C and PHP code. The code of the Scriptol language is intuitive and simple. Instead, the PHP code is inherited from old languages such as C and the command line language of UNIX, Bash, designed to limit the consumption of resources and not to improve the productivity of programmers A clear syntax Scriptol doesn't need for semi-colon at end of statements. The end of the line is also the end of the statement unless several statements fits on a same line, in this case they are separated by semi-colons.
If an instruction fits on two lines, the compiler is able to recognizes it. C++ syntax: for(int x = 0; x < 10;x++) { printf("%d\n", x); } PHP syntax: for($x = 0; $x < 10; $x++) { echo "$x\n"; } Scriptol syntax: for int x in 0 .. 9 print x This is also the choice of JavaScript (they are optional), of Go. Objective design for ... Universal operators Scriptol doesn't use an operator for different usages, as C uses & for deferencing or for binary and, and a same operator should have the same usage in different statements.

AddIceCandidate The addIceCandidate() method provides a remote candidate to the ICE Agent. In addition to being added to the remote description, connectivity checks will be sent to the new candidates as long as the ICE Transports setting is not set to none. If the candidate parameter is malformed, throw a SyntaxError exception and abort these steps. If the candidate is successfully applied, the user agent MUST queue a task to invoke . If the candidate could not be successfully applied, the user agent MUST queue a task to invoke with a DOMError object whose name attribute has the value TBD (TODO InvalidCandidate and InvalidMidIndex).
Note What errors do we need here? Return type: void addStream Adds a new stream to the RTCPeerConnection.

Getting the code and building Create a working directory, enter it, and run: $ gclient config Android specific steps. * Select build system (optional for all OSs except Android where ninja is mandatory) $ gclient sync --force Starred (*) items are described in their own section below and should be performed, if at all, in place. Notes If you're a committer, substitute https for http. On Windows, use gclient.bat instead (or prefix the commands by invoking python).
Android requires that you build on a Linux machine. The gclient sync command fetches dependencies and generates native build files for your environment using gyp (Windows: ninja/Visual Studio, OS X: ninja/XCode, Linux: ninja/make, Android: ninja) . $ gclient runhooks --force Android Specific Steps If building for Android these steps should be inlined above. $ echo "target_os = ['android', 'unix']" >> .gclient.
