• The Database
  • Ahmdahls law (slowest Part will be the Bottleneck)
  • Database Abstraction, make Databases portable (indipendence)
    • Web 2.0 Sites should not use Database Independence
    • B2B should use DI
    • Use the Advantages the DB System gives you
    • Use Data Abstraction instead DBAbstraction
    • Advantage of Data Abstraction: hire DBAs and only give them Interface
  • if your Problem is mappable in Wordpress, use it for christ sake
• Toy Sites
  • if you know the Bounderies, use a Framework
  • inefficency isnt important for Enterprise but not for customer face sites
  • PHP Developers are Jackhammers :)

• Standardization
  • many Coders know Rails but not Ruby
  • many Coders know PHP but don't know the Core
• Where PHP rocks
  • ease, simple, direct, ugly
  • Tim Bray, whenever i code PHP my heart goes black
  • PHP is the shortest distance between two points
• solves Errors
  • Design Pattern can be used to fix Errors in Code Design
• other Stuff
  • Memcache is L2 for APC
  • low level Objects send Alertnotice to High level Objects, High level Objects send listeners then

(advantage is you could deactivate the listeners and dont have to deactivate low level Objects)

• DO AB TESTS for everything (smiley face at end of subject line does 20% more clickrate)
• examples for good framework design
• top 100 Webseites - 40% dont use PHP, 60% do
• AJAX is replacing default Templating Systems in PHP
• NOT Ajax but AJAJ (AsynchronousJavascriptAndJSON) JSON is easier to use on ClientSide
• db is not longer the Bottleneck thx to Memcache
• bind lightly, Loose Coupling
  • memcache was developed by PERL Developer, now most commits are coming from PHP Devs
  • Design Patterns are coming from Java DEVS, now Java Devs are entering PHP
  • Ruby is multithreaded, you have to use CloudComputing and it's developed many usefull tools (GitHub, CruiseControl)
• Conclusion
• Dont say Fuck you, blog this!
