Browserscene: Creating demos on the Web

  1. 1. NE CE S b R e E W S he W on t O os kes R m B de Ro bH aw ing at CreHi, I’m Rob Hawkes and I’m here tonight to talk a little about creating demos using the latestWeb technologies.I call it the browserscene, but feel free to call it the demoscene on the Web.
  2. 2. If you don’t already know, I work at Mozilla.My official job title is Technical Evangelist, but I prefer Rawket Scientist, which is what it sayson my business card.Part of my job is to engage with people like you and me about cool new technologies on theWeb.
  3. 3. Created by Phil Banks (@emirpprime)Aside from that I spend most of my time experimenting with HTML5 and other cooltechnologies.I basically have an addiction to visual programming and hacking around with code.It’s fun!
  4. 4. I’ve never been to Finland before, and for some reason I thought it would be really cold overhere.Turns out it’s hotter than England, and way flatter than I imagined!
  5. 5. yo u r fo xists dy rea hnolog ye are he tec sers T row BOver the past few years browsers have come on leaps and bounds with the types of thingsthat they can do.What’s been particularly interesting is the focus on audio and visual media with theintroduction of HTML5 and JavaScript APIs.This now allows us to create things like this…
  6. 6. This is No Comply, a WebGL and audio demo created by Mozilla volunteers to show off thetechnologies.
  7. 7. s? g ie o lo rs c hn ow se e br e t da y’s th res in to are tu at Fea WhLet’s run through some of the most interesting of these new technologies, the kind of onesyou might want to use.
  8. 8. GL eb & W phics vas 3D gra an and C 2DCanvas & WebGL

  15. 15. s? gie olo ns chn freaso te so ese Lot th use hy WSo these technologies are cool and all, but why should you be using them over others, likeFlash?
  16. 16. o l g co thin s now e m The timei f so ld o o resh ThIn short, the time is now; we’re on the threshold of something awesome.We can now create amazing demos, visualisations, and games with nothing more than thetechnologies we would normally use to build a website.This is definitely a good time to be developing on the Web.
  17. 17. um inim ght a m ei tw igh s to ode isl ing he c th T ing eep KThe code and assets are inherently lightweight.Text and image files don’t take up much space.
  18. 18. in s g lu ork n p o tw nce hings jus lia T o re NYou don’t have to download and install anything for a demo to run; it just works.It’s just HTML and JavaScript.
  19. 19. ree is f n t ch e m er and spee lop eve as in be D FreeDevelopment can be completely free.You don’t need to pay for any editing tools.You could easily use a simple text editor, or the browser itself.
  20. 20. e n idd r h ve d o he lo pile Sharin gt com ’t e isn od CNo compilation; the code is completely open for others to look at and learn from.I find this kind of open development gives me a warm and fuzzy feeling inside, but thatmight just be because I’m slightly crazy.
  21. 21. o s d em ed n e at rs ce lready cre se ea row ersh av g b oth at tin Wh ExisNow, let’s take a look at some of the cool demos that others have put together with thesetechnologies.

  33. 33. Keylight
  34. 34. This is something I made especially for Assembly.It’s an audio visualiser that uses WebGL and HTML5 Audio.If you stick around for my seminar at 1pm I’ll be running through the code behind this.
  35. 35. os d em m e r he o th ated t ot o f dic d s es de dre eb sit un arew H Th ereThese are really just a few demos that are out there right now, and the list is growing everyday!There are some great sites to keep track of the latest ones.

DEV DERBY Experimenting with the latest Web technologies Every month This month is the History API Manipulate browser history Win prizes (like an Android) Next month is Geolocation DEVELOPER.MOZILLA.ORG/EN-US/DEMOS/DEVDERBYAlso, you should definitely take part in the Dev Derby, which is a monthly competition run bythe Mozilla Developer Network to see what can be done with the latest Web technologies.This month the focus is on the History API, which allows you to manipulate the history of thebrowser so things like AJAX don’t break anything.The winners get cool prizes, like an Android phone. It’s a great excuse to play around withthese technologies.
