It's only a weekend to go now until I start at the BBC in their Software Engineering Graduate Scheme in Manchester, and I'm really looking forward to it.

The Web has a problem.

On 19th July 2012, a fissure was created between the W3C and the WHATWG; the two most important standards organisations leading the development of the Open Web Platform.

When I first went to study Computer Science at university, I was curious exactly how my department would approach teaching the students of today about our modern and now very powerful Open Web Platform.

Encrypted Media Extensions.

Ever since the mid-noughties, there has been a general disdain for Internet Explorer.

Ever since Google Chrome launched in 2008, it has used the layout engine WebKit for dealing with all of the functions a Web browser needs to display Web pages to users.
