YUI Theater — Nicholas Zakas and Victor Tsaran: “Accessibility on the Yahoo Homepage (58 min.)”

In June, Yahoo! hosted a BayJax meetup dedicated to web accessibility. Nicholas Zakas, Yahoo! homepage developer, and Victor Tsaran, Yahoo! senior accessibility program manager, gave a talk on the process of making Yahoo!’s homepage highly accessible.

We apologize for the uneven audio levels: there were technical issues with the microphones that we unfortunately were only able to adjust towards the second half of the talk.

YUI contributor and former Yahoo Chad Auld emailed us to tell us about his latest project with his Brilaps group — a project that has brought YUI Theater to the TV screen via Boxee. In Chad’s words:

Boxee is an up-and-coming cross platform application that aims to help bring web content to the TV. It is based on the open source XBMC project and allows users to write new plugins to bring in additional content. We launched a new project about three weeks ago to build our first Boxee plugin, and we selected the YUI Theater as the content we wanted to bring from the web to the TV. There are so many great videos archived there (and growing), we think it is a terrific source of content for developers to have access to from their couch (especially since most of the videos are a bit longer than someone might have time to watch comfortably from their laptop). It took us about a week to build the plugin, another week to polish it up and sort out a few bugs, and about a week to get the application approved by the Boxee QA team and pushed into the public repository. I just got word that it hit the public repository this morning and so I wanted to reach out and let you know.

This is fantastic news for anyone who has been enjoying YUI Theater content and would like to catch up on the latest from Douglas Crockford, Brendan Eich and all the other great YUI Theater speakers from the comfort of his/her couch. Check out the video above for a tour of the UI, and then go grab Boxee and get started.

YUI Theater — Ryan Dahl: “Introduction to NodeJS” (58 min.)

Allen Rabinovich — Thu, 20 May 2010 21:26:05 +0000

Two weeks ago, Yahoo! hosted a BayJax meetup dedicated to NodeJS (since the meetup coincided with Cinco de Mayo, we named it ‘Cinco de Node’). Ryan Dahl, the creator of NodeJS, gave a talk on the project and was very kind to let us record his presentation for YUI Theater.

P.S. The video opens with a 30-second glimpse into the Cinco the Mayo celebrations at Yahoo!

Elijah Insua, a star developer from Arc90, presented his work on jsdom at the Cinco de Node BayJax event at Yahoo!. Elijah was presenting from Brooklyn via Skype (so please forgive the less-than-ideal video and audio quality), and graciously allowed us to capture his talk for YUI Theater.

YUI Theater — Adam Granicz: “Robust and Rapid Web Development with WebSharper” (57 min.)

Eric Miraglia — Sat, 24 Apr 2010 04:49:35 +0000

Adam Granicz stopped by Yahoo! earlier this week to talk about the F# programming language and its use in web application development.

Granicz’s company, Intellifactory, produces the WebSharper platform. WebSharper fills the role in the F# community that GWT and similar tools fill in the Java community, promising a strongly typed, fast, tightly integrated development experience with deployment to rich web applications. As Fybit’s Riatrax4JS and yui4java do for Java developers, WebSharper brings the power of YUI 2 to F# developers, making a wide range of YUI widgets available.

Eric Miraglia — Wed, 21 Apr 2010 18:36:23 +0000

The April 2010 edition of the BayJax meetup at Yahoo! featured five speakers, all of whom are co-authors on the new High Performance JavaScript volume from O’Reilly (free chapter available here). There were about 200 attendees filling the URLs Cafe in the heart of Yahoo!, and they heard five distinctly interesting takes on web-app performance.

YUI Theater — Douglas Crockford: “Crockford on JavaScript — Part 5: The End of All Things” (94 min.)

Eric Miraglia — Thu, 08 Apr 2010 20:35:10 +0000

The final installment of the Crockford on JavaScript lecture series begins like this:

I believe that children are our future. And also, I believe, robots. Children and robots…

He turns quickly to issues of security in the browser:

The worst of all of its security problems is the so called cross site scripting attack, or XSS. It’s not called CSS because that would be confused with the Crappy Style Sheets system that’s in the browser. It really shouldn’t be called cross site scripting either, because there are modes of this attack which have nothing to do with operating across sites. You can have one of these attacks happening within a site. What it really is is a confusion of interest attack. One thing that’s unfortunate is that the security experts who identified and named it got it wrong, and have not corrected it since then, and expect all the web practitioners to be adopting their broken jargon. We’re going to talk a lot about these classes of problems, and how we’re going to fix them.

YUI Theater — Douglas Crockford: “Crockford on JavaScript — Episode IV: The Metamorphosis of Ajax” (93 min.)

Eric Miraglia — Tue, 09 Mar 2010 20:40:38 +0000

Last week, Yahoo! JavaScript architect Douglas Crockford delivered the fourth installment of his Crockford on JavaScript series:

Volume One: The Early Years
Chapter 2: And Then There Was JavaScript
Act III: Function the Ultimate
Episode IV: The Metamorphosis of Ajax
Part V: The End of All Things (March 31 — RSVP)

In this session, Douglas tackles the DOM. On the one hand there was JavaScript, he says, and JavaScript is “what made the browser work.”

On the other hand, there was the Document Object Model, also known affectionately as the DOM. It is what most people hate when they say they hate JavaScript. Most of the people who say they hate JavaScript don’t know JavaScript, might have never seen JavaScript, but they’ve felt the DOM alright. If you don’t know what the difference is and you say, “JavaScript is the stupidest thing I’ve ever seen,” you’re not talking about JavaScript, you’re talking about the DOM. The DOM is the browser’s API. It is the interface. It provides JavaScript for manipulating documents.

The DOM may be imperfect, but it’s nonetheless crucial to what frontend engineers do when they write web applications. In this talk, Douglas provides an overview, situated historically, of where the DOM came from, how it achieved ascendance with Ajax, and what the future might hold. In Douglas’s inimitable fashion, this history starts with Sir John Harrington and takes us up to the present day. A few choice words for CSS are among the many applause lines for veteran developers:

I find within the community of people who use CSS great affection for it. They’re totally invested in CSS, they love it. They can’t imagine any other way of doing formatting in a document. It’s it. It’s sort of like watching an episode of Cops where the cops come in and break up the family dispute, and there’s this “CSS ain’t bad, you just don’t understand it like I do. I know it hurts me, but I make mistakes, I’m wrong.” CSS is awful, and it amazes me the way people get invested in it. It’s like once you figure it out, kind of go “oh, OK, I see how I might be able to make it work,” then you flip from hating it to loving it, and despising anybody who hasn’t gone through what you’ve gone through. It doesn’t make sense to me.
