Tech Presentations

Another interesting presentation about web performance from Yahoo!’s Exceptional Performance team, this time by Stoyan Stefanov, lead developer, YSlow.

20 more tips-n-tricks, a couple new tools and more interesting numbers. I wish there was a video with all minor details that slides don’t convey.

Presentation about how PHP is used at Yahoo!, by Michael J. Radwin given at MySQL User Conference on April 26, 2006 (PPT slides) (previously at Zend/PHP Conference - PDF version).

Some quotes:

• May 2002: yScript -> PHP
• Why we picked PHP
  1. Designed for web scripting
  2. High performance
  3. Large, Open Source community
     • Documentation, easy to hire developers
  4. “Code-in-HTML” paradigm
  5. Integration, libraries, extensibility
  6. Tools: IDE, debugger, profiler
• ./configure –disable-all
• Security: open_basedir, allow_url_fopen = Off, display_errors = Off, safe_mode = Off; input_filter hook
• Performance: Opcode Caches, PHP Extensions in C++
• Globalization: PHP Unicode (2006)
