Editor's Notes

  1. Forget what you thought you knew
  2. On the Monday night before Velocity started on Tuesday I had dinner with some other attendees and I was listening to a conversation about a Chef with a Knife in the fog and some precious stones chasing a Puppet. WTF?
  3. Its all about automation and configuration management in the cloud.
  4. Un-modified data centre apps will not work in the cloud
  5. Its not about how many servers you manage any more its about how flexibly you manage themThe Amazon & Heroku presentations were very good in this regard.
  6. BTW live tweeting is a good way to take notes!!!
  7. Velocity is very pro open-source tools & toolkits
  8. Im not arguing open vs closed source, just pointing out that Velocity is a bit of an open-source echo chamber
  9. In fact there were very few presentation that, IMHO, actually told you anything new about web performance.
  10. The MSN performance talk was excellent http://velocityconf.com/velocity2011/public/schedule/detail/18039Performance improvements can increase and DECREASE your bottom line so be careful!
  11. A lot of presentations flirted around the edges but there is still nothing definitive (IMHO)
  12. Here is one reason why a mobile browser isnt the same as a desktop browser.(on Android) the web browser is a Java App calling a C/C++ app which calls another C app
  13. Decisions in the Face of Uncertainty or Just Enough Statistics to be DangerousLook at Your Data
  14. Decisions in the Face of Uncertainty or Just Enough Statistics to be DangerousLook at Your Data
  15. Build your won adventure was just a great practical talk and a lot of fun!
  16. Lots of great, pithy advice in Adams talk!
  17. The cloud will become a ubiquitous, seamless part of everyones live. What sci-fi authors call an exo-memory and we are building it, right now.
