Ai technical lead David Yoon made a great compilation of Web 2.0 Expo observations, below. This wraps our conference coverage.
General points from the conference:
Technology: the conference from a technology perspective was very heavily focused on just a few topics:
– cloud computing and the problem of scaling websites
– next generation of browsers and bringing web applications even closer to desktop applications
10 things we’ve learned at 37 signals
–I thought this was one of the better talks of the conference
– planning is overrated/decisions are temporary/optimize for now
– create waves of interest — momentum is very important
– interruption is the enemy of productivity
– out-teach, out-share, out-contribute
– most of these points are applicable for small, non-client facing tech shops
Go REST with Rails
– DHH gave a great talk about REST and Rails, aka reasons for a restful architecture (mainly for communication/interaction between sites), and discussed some of the features that are built into the framework to handle it. Most developers here already know the principles/reasons but it was a good presentation.
– Support in rails 2.1 for etags/not modified headers
Building in the Clouds: Scaling Web 2.0
– Panel discussion about cloud computing from a variety of companies (google, 10gen, amazon), where it currently is and how to make best use of it.
– Ability to scale massively in a very short amount of time – example of the facebook photo application that scaled from 5 servers to 5000 in a week using amazon.
– Not suited to all application/companies, developing for cloud applications requires a shift in developer mentality.
– Relevancy/importance of cloud computing
Designing for the Internet(s) of the future
Very interesting talk by Genevieve Bell – anthropologist researching trends in global internet usage
– China now has more active internet users than the US, this trend will continue
– Internet is becoming widespread in the developing world, though generally it’s become shared (1:many people per device), asynchronous (delay of days/weeks between the transfer of information)
– Trend toward disconnecting from the internet
– Concerns: Privacy issues, cultural health
The sequel to SQL: Why you won’t find your RDBMS in the clouds
Great technical talk about object databases/cloud computing.
– scaling databases: partitioning (sharding) over multiple servers is hard/slow when using relational databases
– object databases
– examples: BigTable (google), SimpleDB(amazon), Mongo (10gen)
– pros: scaleable
– cons: – no joins across tables…
– eventually consistent (not good for banking transactions)
– query limits (1000 entities for google, 250 for amazon)
State of Web Development
– chrome/gears, web applications are becoming more and more like desktop applications
– js will become *really* fast in the next generation of web browsers, the language will potentially have much more influence
– rise of Ajax as the important medium for providing a better user experience.
