Editor's Notes
- #3: Forget what you thought you knew…
- #4: 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?
- #5: It’s all about automation and configuration management… in the cloud.
- #9: Un-modified data centre apps will not work in the cloud
- #11: It’s not about how many servers you manage any more… its about how flexibly you manage them…The Amazon & Heroku presentations were very good in this regard.
- #12: BTW live tweeting is a good way to take notes!!!
- #13: Velocity is very pro open-source tools & toolkits
- #14: I’m not arguing open vs closed source, just pointing out that Velocity is a bit of an open-source echo chamber…
- #15: In fact there were very few presentation that, IMHO, actually told you anything new about web performance.
- #16: 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!
- #17: A lot of presentations flirted around the edges… but there is still nothing definitive (IMHO)
- #19: Here is one reason why a mobile browser isn’t 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…
- #21: Decisions in the Face of Uncertainty or Just Enough Statistics to be DangerousLook at Your Data
- #23: Decisions in the Face of Uncertainty or Just Enough Statistics to be DangerousLook at Your Data
- #25: Build your won adventure was just a great practical talk and a lot of fun!
- #26: Lots of great, pithy advice in Adam’s talk!
- #27: The cloud will become a ubiquitous, seamless part of everyone’s live. What sci-fi author’s call an “exo-memory” and we are building it, right now.
