WebSockets - An Introduction

WebSockets is a modern HTML5 standard which makes communication between client and server a lot more simpler than ever. We are all familiar with the technology of sockets. Sockets have been fundamental to network communication for a long time but usually the communication over the browser has been restricted. The general restrictions

The server used to have a permanent listener while the client (aka browser) was not designated any fixed listener for a more long term connection. Hence, every communication was restricted to the client demanding and the server responding.
This meant that unless the client requested for a particular resource, the server was unable to push such a resource to the client.
This was detrimental since the client is then forced to check with the server at regular intervals. This meant a lot of libraries focused on optimizing asynchronous calls and identifying the response of asynchronous calls. Notably t

The button click in JavaScript

I have always wondered why the button click could be simulated using the document.element.click() event. I mean if only we could ensure that any click event that originates must be a click event because of user interaction, it would make life just a step better right ! So many form submits under malicious circumstances could be avoided. [For the technically informed: Of course there are workarounds that need other mechanisms in place]. A sample code of how this can be done is here

So this week I was working on the HTML5's full screen API. I am not a major audio/visual person so I have not had the pleasure of exploring this API before. I was planning on hosting a presentation online. Like many of us I chose to use JS to write this 'modern' presentation. In my computer, I generally use the presentation mode of chromium thereby making it a good solution without the need to use the terrible api of HTML5. It is not terrible because of the spec

What is this

In latex there is a problem with adding long equations to a paper. Suggestions like converting the equation to a figure first are more troublesome than any help. The physics journals have already implemented something called widetext and this is quite useful. That being said, this is a very simple feature. It exists, though guides are not quite useful.

Instructions are below ..
