The 34-Blade Razor from Yahoo!

Congratulations to my friend and colleague Stoyan Stefanov for the publication of Yahoo!’s Latest Performance Breakthroughs after presenting them at the PHP Quebec Conference in Montreal last week. The 20 new tips bring to 34 the total performance tips his team at Yahoo! has published in the past two years.

Stoyan (who authors the phpied.com blog) is part of an established tradition of Yahoo! sharing performance research publicly and widely. Stoyan’s teammate Tenni Theurer concluded the official blog post announcing these data and findings by saying, “We share our findings so that others can join us in accelerating the user experience on the web.”

I agree. That’s why I was honored to help disperse their 14 Rules for Faster Web Sites in my presentation at the @Media conference in London last year.

And that’s why it was a special honor to write the foreward to Steve Souders’ High Performance Web Sites book for O’Reilly last year. (Steve used to head up the Performance team at Yahoo!.) In the foreward I tried to express why performance matters to professional frontend engineers:

Here is why it matters. As a frontend engineer, you hold a tremendous amount of power and responsibility. You’re the users’ last line of defense. The decisions you make directly shape their experience. I believe our number one job is to take care of them and to give them what they want—quickly. This book is a toolbox to create happy users (and bosses, too). Best of all, once you put these techniques in place—in most cases, a one-time tweak—you’ll be reaping the rewards far into the future.

Presenting YUI at OSDC.TW in Taipei

It’s just been confirmed and announced that I’ll be speaking in Taiwan at the Open Source Developers’ Conference on the 12th and 13th of April 2008, on the campus of the School Of Continuing Education, Chinese Culture University in Taipei. My talk will offer an insider’s tour of the YUI Library:

The YUI Library is an open-source, a la carte JavaScript library for building richly interactive Web apps using techniques such as DOM scripting, DHTML, and AJAX. This library, free for the world to use, is the exact same code that is used globally and at massive scale on scores of Yahoo! sites. In this session, Yahoo!’s Nate Koechley will talk (and answer questions) about the design and technical philosophies behind YUI. You’ll learn what the library can do for you, where it’s heading, why and how Yahoo! decided to open-source it, and how you can use it to provide an outstanding user experience for your visitors.

Carbon Neutral Purple

I know there’s a bit of a backlash against Green because its so trendy lately, but I can easily put that aside and be happy that things are changing. That takes on special meaning today because I just saw that Yahoo! is quickly following promises with real action, and making what seem to be excellent, well-researched green choices.

When Yahoo! committed to going carbon neutral in April, we knew it would be a global initiative. … After much due diligence, Yahoo! has decided to offset its 250 thousand metric ton carbon footprint from 2006 through hydropower in rural Brazil and wind turbines in India. We’ve partnered with EcoSecurities and CantorCO2e, who helped us source, vet, and execute these projects.

(Some are still skeptical about carbon offsets, but I see any step as a great early step.)

YSlow, a Web Performance Plugin for Firebug, Release by Yahoo!

I let the cat out of the bag about the forthcoming YSlow plugin for Firebug during my @media presentation (High Performance Web Sites) last month. But the wait is finally over and I’m happy to let you know that Steve Souders, Yahoo!’s Chief Performance Yahoo! (and the guy who’s data I used in my presentation), made the announcement during his session at OSCon yesterday.

YSlow has three main views: Performance, Stats, and Components. Performance view scores the page against each performance rule, generates an overall YSlow grade for the page, and lists specific recommendations for making the page faster. Stats view summarizes the total page weight, cookie size, and HTTP request count. Components view lists each component (image, stylesheet, script, Flash object, etc.) in the page along with HTTP information relevant to page load times. It also contains several tools including [Douglas Crockford's] JSLint.

Give YSlow a try, your users will thank you. And for more about performance, check out the Exceptional Performance section on the Yahoo! Developer Network.
