My Notes:

  • Cassandra differs
    • No relational schema
    • Create columns and column families
  • Good for
    • Large scale sites with lots of similar data
  • If don’t have enough data for 8 node cluster (25 GB per cluster), not looking to grow to TB, probably better sticking with traditional database infrastructure
  • Cloud Computing
  • Why are open standards important? Enterprises are hesitant to repeat work – especially in a new environment.

My Notes:

  • Biggest issues with ads and site performance
    • Network latency – no control over various assets retrieved
  • Expectation
  • No fair to expect site with advertising to perform as well as no advertising
  • Unless ad is served in an iframe
  • What can be done
    • Develop plan to minimize impact of 3rd party code on site
    • Work with CMS
    • Order items are loaded on the page
  • Single thing to improve ads and site performance
  • Get rid of document.write in javascript ad – allow site developer to have control of when to call loading of assets
  • Optimum ad slots: 2 should be enough

My Notes:

  • Yahoo home page reorg in 2009
    • Moved from static to interactive / customizable
  • Time to interactivity metric
    • Time between hitting enter on URL and can complete an interaction on a page
    • Sometimes even before the page has finished loading
    • Aim to minimize this time
  • Metrics we should avoid
    • Most are useful
    • Should not focus in on any one item
    • Focus will depend on the usage pattern of the page
  • Yahoo home page as an application framework
    • People think of it as a single page
    • Same framework is running home page around the world
    • Difference between building an application and an application framework
