dotJS 2012 in review

Sun Dec 2, 2012

These are roughly 2000 words, you could read this in about 9 minutes.

dotJS in Paris was awesome, here's a recap.

In summer 2012 when dotJS was announced I immediately bought a ticket. While JavaScript is not my beloved development language it surely can achieve great things if you just bend it to your will. And it sure is resistant when compared with other languages such as Ruby, Python or even the C language family.

Two days ago the day of the conference finally arrived and I have to admit: I was excited. While there was a posted schedule, and a list of speakers available, and on top of that a few workshops had been announced for free on the day after, all of us did not know which topics would actually be covered.

The venue

Oh boy, this was one hell of a location. Or yet better said it was by far the most awesome location I’ve had a conference in. With the Théâtre des Variétés a classical location had been chosen for such a modern topic, and the combination did not only impress me as I could gather from other participants.

When I arrived for registration the entry already was full with probably a hundred participants waiting. A few minutes after eight, the doors opened and people dived into the venue being handed badges with their names, and a few goodies like mongodb mugs.

The sessions

JavaScript and Unicode characters

Mathias Bynens, creator of jsperf.com.

It all started with a talk given by Mathias Bynens on a rather different topic: JavaScript, and Unicode characters. Not quite the popular topic, since handling Unicode characters is on of the language aspects not really well implemented.

Mathias Bynens... for I shall browse the Unicode character list more often!

The journey included how far Unicode went to implement characters like the snowman (U+2603) and the pile of poop (U+1F4A9),

Web components in Enyo

Kevin Schaaf, Enyo framework.

Kevin Schaaf continued the track with a talk about componentized JavaScript, and how the Enyo framework tries to solve the issue.

In his talk he talked how JavaScript can and should be componentized so that it becomes easily extendable, and used Enyo to showcase which solution they chose for their project.

While the talk was more of an introduction to Enyo and a rationale for using it, it also helped me quite a lot with my own endeavors since it pretty much confirmed my own roadmap for JavaScript usage in future projects. I saw a few similarities with ExtJS by Sencha, but I have to admit Enyo is much more than ExtJS. Where ExtJS is more about visual components, Enyo is more about reusable components, and mainly being able to inherit, extend and build upon components.

What I liked most was how you can extend a simple Enyo component from just a form label and input up to a customizable profile view. Nicely done!

Also interesting to hear that the roots of Enyo are to be found in WebOS, where all applications are web applications actually, though the look like native applications.

Tooling for the modern web app developer

Addy Osmani: created TodoMVC, Aura, Yeoman, and part of the jQuery team.

What started with an instance of google Chrome Canary quickly turned into a showcase for how you can leverage the goodies making their appearance in Chrome with each new release much earlier.

If you have not yet tried Canary, get it and use it. New features in the development tools of Chrome include stuff such as overrides for which mobile device your browser should emulate, and Chrome even does so with proper font zooming. Exactly what I was looking for. Also, as a regular user of SASS and Compass I noticed the inclusion of Source Mapping for both SASS generated style sheets, and also for CoffeeScript generated JavaScript. Is there more to say than I want this? I doubt it.

Addy Osmani... Canary -- Chrome unstable -- tools shown by Addy Osmani

And while we are at it, give Tincr for Chrome a try. Live reloading is one feature, but what I even liked more:

You can make changes in the loaded site, and even switch between changes.

Since Addy Osmani obviously likes what he presented a lot, he took his fair share of time for the track, and was probably around 13 of the topics he wanted to cover, when the track time was up. As expected he quickly mentioned Yeoman>, and did a quick showcase. If you do not know Yeoman, go read up, and make use of it.

Where is Node.js 1.0?

Bert Belder, member of the Node.js core team.

With Bert Belder on stage, the topic finally switched to Node.js, and he tried to answer what is actually missing for Node.js to release a version 1.0 – Obviously a question quite frequently asked.

Well, the answer to that was pretty simple: there are features left, to which Node.js needs proper implementations before a 1.0 release would be made available.

Bert Belder... What is in Node.js 1.0? Boxes, streams, probably awesome sauce!

Streams for one would be getting filters like crypt, or zip, and much improve reading and writing. Not much to say here, as it seems that the final implementation has not yet been decided on.

Boxes … those have been a topic in better shape, since it’s been pretty much decided how they are supposed to work. What boxes are? A method to put critical parts of your Node.js application into boxes which will no longer crash the whole process, but instead just die with an error you can actually handle.

Boxes also promise methods to dynamically add more stuff to existing boxes, among a few other enhancements. I’m very much looking forward to seeing more on those.

Open Source “like a boss”

Charlie Robbins: CEO / Co-Founder of nodejitsu.

With Charlie Robbins on stage, the topic shifted away from technical talks to a more philosophical topic, which at this point really was a welcome change.

The track talked about how to manage Open Source projects effectively, while improving the participants, and also not going insane. The later one is especially of importance. I can relate to that from personal experience. Being active in Open Source for almost eight years now, I have had my fair share of moments when I felt like going insane.

Grab the presentation now!

Interestingly Charlie Robbins focused on the importance of people, and especially on equality among peers. Luckily for you, Charlie has put the presentation up on github for you to enjoy, too. It’s rather refreshing to see the other side of the development business – and Open Source definitely is business – in a different light.

Symbiotic languages

Jeremy Ashkenas: creator of Backbone.js, Underscore.js, and CoffeeScript

Jeremy Ashkenas talked about Dart, TypeScript, and CoffeeScript and how they abstract the ugly parts of JavaScript into something more beautiful.

Each of them has a different approach, and their very one benefits. Where CoffeeScript tries hard to stay JavaScript, and only hide the ugly parts,

Dart is more of typed language, and adds language features which JavaScript lacks. Also, Dart is more of an approach to building web apps, rather than just an abstraction for JavaScript.

TypeScript is pretty similar in that in adds types, and also focuses on building apps with it.

Personally I just can’t weigh in here, I just started to dig into CoffeeScript and still have to decide if there’s value in symbiotic languages for me, or if there is not.

WTF JS?!

Brian LeRoux: PhoneGap lead.

Much like Mathias Bynens, Brian LeRoux introduced quite a few of the funnier sides of JavaScript to us, and hell, he gave a fun talk. Basically he popped open a console, and showcased where JavaScript gets weird.

Check out wtfjs yourself. Quite hilarious, and good to know, where things get ugly. Usually these topics are left “as an exercise to the reader”.

Game development in HTML5

Christian Amor Kvalheim: created the MongoDB driver for Node.js.

Now this was quite different show. Christian Amor Kvalheim declared his love for Pacman and described how he ventured into game development in HTML5 with Node.js to build a networked version of Pacman, where one becomes Pacman, and connected players would become the ghosts.

Mongoman is the result of his efforts, and I can only recommend to give it a try yourself.

Stories of inspiring people

Vojta Jína: member of AngularJS team, Testacular.

Vojta Jína weighed in on the people talks with his track, and talked about the people behind Open Source projects, and how they came to be who they are, and how they managed to inspire shit loads of other people, and of course himself. Ryan Dahl, John Resig and Dennis Ritchie being mentioned here. Pretty good choice!

To sum this up: combine existing projects, solve issues with these in new creative ways, and be passionate about it. Node.js is the result of such an effort, and many other famous projects are so, too.

Tools for designers

Ricardo Cabello: also known as Mr.doob, and creator of three.js

Ricardo Cabello started by showing how tools can help designers to build better results by giving a tour on 3D demos over the past decade, and how working with tools has changed the process.

Being an ex Commodore 64 user myself, it was quite awesome to see how the demo scene has managed to survive and evolve. Charging by the look of the demos, professionalism has arrived in the scene quite a long time ago.

Ricardo specifically mentioned that currently it may even take five years work to top whats currently on top of the ladder in the demo scene.

That much dedication and effort is truly impressive.

I have to admit, right after the talk I was tempted to install an emulator for the Commodore 64 and rewatch some of the old demos.

History of Open Source

Jacob Thornton aka fat: Bootstrap, Hogan.js, and Ender.

This one was really, really awesome! Hand-drawn pictures of various Open Source figures like Richard Stallman or Linus Torvalds with a really cute touch, and his very own puppy theory on how your own Open Source projects evolve over time have been quite the awesome end of the day.

Not to mention that Jacob simply was hilarious, and brought feelings to the track which all of us in the audience somehow had experienced with Open Source and “our children” released.

The conference

Overall I have to admit that – while a primer – the conference really was great. Organization was great, and the team did an awesome job during the day, too.

Did I mention the food yet? If not, man… that stuff was so good, I have to stay in my kitchen for the next days to try cooking that food for myself.

Hilarious choice of smoothies, too. Nodeberry and Backbonana

Only issue here… we probably had too many smoothies in the end, and suffered from brain freeze. But they where so tasty! Couldn’t resist.

My final vote: next dotJS will see me going there again!


P.S. I have to admit, I have not taken any notes during the lightning talks where various people got the option to talk for five minutes, and I dearly regret that. Everyone tried hard, and did well. Interesting and amusing!
