The Next Web’s developer brand, Kings of Code, is holding its fourth festival in December, with an event focusing on the latest trends, developments and best practices in web and mobile development technologies.

Running from 1-4 December 2012 in Amsterdam, Kings of Code is a four-day developer festival that will see leading international speakers and developers talk topics such as the future of HTML5, Front-end & backend development, Mobile, Realtime, CSS3, Go!, PHP and Javascript.

Besides being able to catch the last discounted early bird tickets, here are five reasons to attend.

1) Polish your knowledge – the biggest names in development

An inspiring line-up of 18 international speakers from all fields of expertise have been assembled to get you up to speed on the latest development techniques, including Socket.IO author Guillermo Rauch, Jackson Gabbard, mobile engineer at Facebook, Bootstrap’s author @fat and software engineer Vicent Martí from GitHub. Check out the full speaker list.

2) Show your skills – join the 36-hour hack battle

On December 1 and 2, the weekend before the conference, 100 developers will come together during a 36-hour long Hack Battle to build great apps and web services on top of the API’s and SDK’s of Spotify, Sendgrid and many more.

Besides having a shot at the title ‘King/Queen of Code 2012′, every team will be able to present their achievements in front of an audience and a jury. The top three winners are invited to present their hacks on main stage during the conference on Monday. Participation is free and you can sign up alone, or with colleagues.

3) Learn from the best – expert workshop sessions

Learning is great, but doing is even better. On Tuesday the 4th, leading experts will teach you how to use the latest front-end, back-end and mobile technologies during the workshop day.

Want to know how to create a mobile HTML5 application? Or always been fascinated by deploying applications with Chef? The workshop track is for you.
