Yahoo!’s Latest Performance Breakthroughs

Wednesday, March 19th, 2008

The Exceptional Performance team at Yahoo! added 20 new performance rules and refined some of the original rules. I’m really excited about this; this performance goodness is just what developers need to accelerate the user experience even further.

  1. Flush the buffer early
  2. Use GET for AJAX requests
  3. Post-load components
  4. Preload components
  5. Reduce the number of DOM elements
  6. Split components across domains
  7. Minimize the number of iframes
  8. No 404s
  9. Reduce cookie size
  10. Use cookie-free domains for components
  11. Minimize DOM access
  12. Develop smart event handlers
  13. Choose <link> over @import
  14. Avoid filters
  15. Optimize images
  16. Optimize CSS sprites
  17. Don’t scale images in HTML
  18. Make favicon.ico small and cacheable
  19. Keep components under 25K [mobile]
  20. Pack components into a multipart document

Stay tuned, we’ve got more tricks up our sleeve. ;)

CSS 3 and where we shouldn’t be

Sunday, December 23rd, 2007

The emergence of CSS Frameworks doesn’t prove the necessity of a major overhaul of the CSS Spec. Rather it is indicative of the maturity of the medium. Java programmers don’t rewrite the math class every time they code a new application. If you are reinventing the wheel each time you write CSS, you’re doing it wrong.

Semantics for Debutants

Monday, December 10th, 2007

Steve wrote an article about semantics. He does a good job of explaining his process.
We need to teach newbies to take a slightly broader view. Imagine, for example, an action list, which allows you to execute a certain number of actions relative to the context in which it is found. Think; “print”, [...]

Yahoo! Developer Day Conference

Saturday, December 8th, 2007

It is hard to remember not to make any mention of pants, even if I know what it means in British English. Beyond telling Murray Rowen that I liked his underwear in front of a crowd of people, I recently went to London to speak at the Front-end Summit being held there. I gave two talks. The first was High Performance Websites in particular the impact of choices made by front-end engineers. The second talk was about Architecting High Performance CSS.

Clearing floats and printing with Firefox.

Saturday, July 21st, 2007

Half of my resume was missing. It was there on the screen, but in print preview and on the printed page reams of experience disappeared. Not ideal.

I discovered that when you use the formatting context to clear floats, firefox treats each printed page as a “box” with the overflow hidden. Elements with overflow: hidden applied will be printed partially or not at all.

Why are women not on the A-list?

Friday, March 9th, 2007

I’m not a proponent of lowering skill level for diversities sake, but is it possible that there are CSS Goddesses on the A-list in terms of technical skill, speaking ability, and vision who simply aren’t on the radar of the web development community?

Pourquoi des sites au design accessible ?

Monday, March 5th, 2007

Un site accessibles et un site inaccessibles peuvent paraître exactement les mêmes pour un utilisateur qui n’est pas handicapé. Il peut alors être difficile de comprendre les raisons de tout ce remue-ménage. Pourquoi est-il aussi important de tenir compte de cette accessibilité lorsqu’on conçoit et lorsqu’on met en forme des pages Internet ?

A List Apart has launched a new site design. They had a couple seconds of style-less content, and then boom, the new site was born. At first glance it is a 1000px wide, four column design based on ruby on rails. Take a look.

WWW2005 - shameful name dropping

Saturday, May 14th, 2005

I attended WWW2005 in Chiba, Japan, just outside of Tokyo. It was a fun conference. I met lots of great people, and saw some people I hadn’t in a while.

Morgan and the Expanding Container Element

I am working on a site for Mason where he can record his adventures rebuilding a Morgan with his father-in-law. The design is going alright, and I have only two gripes.

WYSIWYG Editor Accessibility Test Results:

Thursday, December 16th, 2004

Allowing writers to contribute to the creation of accessible documents.

The testing was based on the needs of non-technical content contributors; writers, graphic artists, editors, etc. The program had to shield the user from all the code and provide a simple usable interface.

It is reasonable to expect writers to be able to update documents and follow preexisting styles without substantially compromising accessibility. However, they won’t be able to create or change the overall look and feel of the documents. This type of change requires familiarity with CSS and XHTML, even in the WYSIWYG (What You See Is What You Get) environment. With proper planning, this limitation can actually help insure consistency across large documents. . .

Web Design Resources

Wednesday, December 15th, 2004

I became a geek by accident. I was a groupie for ages and then it just kind of rubbed off on me. I am eager to collect my links before they get lost.  The resources for learning to design well are out there, but hard to find and evaluate until you know the [...]
