Enjoying the full stack - Frontend 2010

Enjoying the full stack. Chris&an Heilmann http://www.flickr.com/photos/andrewrennie/4608617962 Frontend 2010, Oslo, Norway, October 2010

We now had two days of awesome web technologies.

We do live in exciting times!

The technologies we’ve been advocating for years are more powerful than ever.

CSS = rocking the interface and taking over tasks that only JavaScript could do.

HTML = application language with reach into predefined widgets and OS data.

JavaScript = the de-facto language for new environments and interfaces.

JS + Node.js = kick-ass server side solutions for today’s problems.

So what keeps us from having a really easy life creating the coolest apps ever?

That’s us, my friends.

Government FAIL http://www.hmg.gov.uk/epetition-responses/petition- view.aspx?epref=ie6upgrade

Complex software will always have vulnerabilities and motivated adversaries will always work to discover and take advantage of them. There is no evidence that upgrading away from the latest fully patched versions of Internet Explorer to other browsers will make users more secure.

It is not straightforward for HMG departments to upgrade IE versions on their systems. Upgrading these systems to IE8 can be a very large operation, taking weeks to test and roll out to all users.

To test all the web applications currently used by HMG departments can take months at signiﬁcant potential cost to the taxpayer. It is therefore more cost effective in many cases to continue to use IE6 and rely on other measures, such as ﬁrewalls and malware scanning software, to further protect public sector internet users.

Who watches the watchmen?

Not us - we are too busy writing effect examples.

HTML5 Showcases

2000 / Windows

1992 / Amiga 500

1994 / C64

Progress is a debt we all must pay.

HTML5 is not about dicking around in a canvas and plotting shiny things.

HTML5 is about moving from documents to applications.

HTML5 is about moving from hacks to solutions.

Real input types, real app state retention, real back button and history support...

...real collaboration of apps over a network...

...real marking up of what things are.

This is all the *really* exciting stuff.

Not rotating a video or simulating some Flash effect in Canvas.

Innovation should not be at the cost of quality.

It's convenience we all cherish.

This is a valid HTML5 document: <!doctype html> <html lang=en> <meta charset=utf-8> <title>blah</title> <body> <p>I'm the content

HTML5 + CSS3 should be a reboot of awesome.

<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>blah</title> </head> <body> <p>I'm the content</p> </body> </html>

Less code does not mean a better solution...

Less redundancy in code is a better solution.

I do not want to trust a browser to right the things I did wrong.

We’ve done that over and over in the past...

...and now we bitch that people do not upgrade...

...and their reason is the solutions they bought for a lot of money...

...that were built with the same attitude for a “cool and simple” environment at that time.

Rotating HTML content?

Matrix filter anyone? http://msdn.microsoft.com/en-us/library/ ms533014%28VS.85%29.aspx

File system access?

.hta anyone? http://msdn.microsoft.com/en-us/library/ ms536496%28VS.85%29.aspx

It's pollution we disdain.

Forking and repeating code for different browsers is not fun.

CSS2 CSS3

box-shadow:10px 10px 7px rgba(0,0,0,.7); -moz-box-shadow:10px 10px 7px rgba(0,0,0,.7); -webkit-box-shadow: 10px 10px 7px rgba(0,0,0,.7); -webkit-transform: scale(1.25); -moz-transform: scale(1.25); -o-transform: scale(1.25);

Let’s take a look at the players.

Opera http://www.flickr.com/photos/dalbera/4824517154

Firefox http://www.flickr.com/photos/harlequeen/887663462

Chrome http://www.flickr.com/photos/jillclardy/2637251419/

Safari http://www.flickr.com/photos/library_of_congress/2809104638

Explorer http://www.flickr.com/photos/statelibraryofnsw/3422714392

Explorer = http://www.flickr.com/photos/statelibraryofnsw/3422714392

Let’s make upgrading a logical step. IE6

Let’s not concentrate on adding new players and random additions. W TF

HTTP + PARSER

Making CSS3 easier to apply.

Give browsers what they can do and use what they do better!

Easing the use of web fonts for better typography.

http://code.google.com/webfonts/preview#font-family=Lobster

Simply adding a link doesn’t give you feedback though...

Using JS to load the fonts on the other hand does.

Classes added to the root element by the Google WebFont loader .wf-inactive .wf-active .wf-tangerine-n4-inactive .wf-tangerine-n7-active .wf-droidsans-n4-inactive [...] n4 - normal i4 - italic n7 - bold i7 - bold italic http://code.google.com/apis/webfonts/docs/webfont_loader.html

WebFontConfig = { google: { families: [ 'Tangerine', 'Cantarell' ] }, typekit: { id: 'myKitId' }, loading: function() { }, fontloading: function(family, info) {}, fontactive: function(family, info) {}, fontinactive: function(family, info) {}, active: function() {}, inactive: function() {} };

Feedback and handles are needed to deliver working solutions.

Web development is not about what technology you love.

It is about using a full stack of technologies and let each do what it is great at.

Each part needing experts and enthusiasts.

And all working together on the goal to make our job easier and more professional.

We should work for the web and for people - not for browsers.

Browsers can be handled by a build process.

View-source is important but should happen on GitHub, not in the browser.

Performance optimisation can be done by machines.

Human optimisation can not be done by machines.

We have a very cool future ahead.

If we build for the humans and use the machines for what they are good at.
