Velocity Europe

I have attended Velocity Europe Conference. Here is what I learned:

Tools for web performance

• YSlow - browser plugin showing how site can be optimized http://developer.yahoo.com/yslow/
  
• Chrome devtools plugin for site optimization
  
• Chrome enable benchmarking - a plugin to show load times with browser cache disabled http://www.chromium.org/developers/design-documents/extensions/how-the-extension-system-works/chrome-benchmarking-extension
  
• Web Page Test - a page testing site performance with improvements tips http://www.webpagetest.org/
  
• Google tools for page optimization https://developers.google.com/speed/pagespeed/
  
• Graphite - tool for visualization f.e. server performance metrics
  

News:

• HTTP 2.0 - Will be decided what it will include in about a 1,5 year. It will be based mostly on SPDY
  

Useful tips:

• Do not implement Javascripts that block. You can use option async + defer (for IE). Then it will not block your page load event, what makes your page beter for google robots and higher in google searches (Google has 3,5 seconds metric for Page Load). Every JS that does not block should be loaded in the bottom of the page and ones that block should be included on the top. Use Modernizr for javascript dependency
  
• If you add a resource in the page starting with https://address or http://address, just use //address
  
• Add performance metrics to DoD
  
• Allow business to measure RUM (Real user monitoring)
  
• Learn every day is the reason for working, otherwise change your work! (From facebook guy)
  
• Take risk. Otherwise you want learn. (Same guy)
  
• Site performance means money for business
  
• It is better to develop a native application on the mobile if you want a fully featured one. It is almost impossible to have one fast rendering on Android and IPhone.
  
• Do not keep server 200 days without restart. It is not updated or it can broke down. (That's why windows 95 had to be restarted. Some unix also had Magic number bug, so they worked only about 200 days)

@RequestMapping view in STS

If you are working with STS and developing Spring MVC applications then you can try option Show View -> @RequestMapping. It will show you what urls are mapped for which Controllers and its methods.

Mercuryapp

Spring Framework 3.2 M2 Released

It contains changes to @Configuration classes, repackagaging all net.sf.cglib classes to org.springframework.cglib and inline them directly within the spring-core JAR.
Both of these upgrades are good news for JDK7 users writing Spring components in dynamic JVM languages, as these new versions of CGLIB and ASM properly handle the new invokedynamic bytecode instruction introduced in JDK7.
