Best of this Week Summary 26 October - 01 November 2009

• Another good summary how merging WOA with SOA could potentially solve (some) SOA problems.
  


• This post covers three major areas of JavaScript/AJAX performance: distributed communication, usability, memory leaks and anti-patterns.
  


• Several interesting details from Facebook’s VP of Engineering about the infrastructure of the company, and the massive scaling problems it has to support. Big role for memcached there. Full video presentation here.
  


• Presentation at Oracle Open World 2009 - how to turn any ADF application into a SaaS application - an application suitable for deployment on the cloud. Includes short description of a SaaS, benefits, concerns, and several requirements. These requirements include customisation of fields shown to the user (e.g show or not show depending on the user or location) and i18n. Technologies suggested to achieve this are Oracle EBR, (WSRP) portlets, WebCenter, deep linking (tricky in JSF) and ESB.

• The TLS Report, a recently started website, is keeping track of how major sites have implemented TLS (Transport Layer Security, formerly SSL). Check the first surprising results of the best and worst here.
  


• Presentation from Jason Sobel, the manager of infrastructure engineering at Facebook, on how Facebook implements the storage of about 6.5B images (profile pics, regular photos) in 4 or 5 sizes, totalling about 30B files, 540TB and serving 475K images per second! Their servers (10K Apache webservers, PHP, Memcached, 1800 MySQL servers) can't handle that so they use CDNs.
  Here's a page from the presentation that shows the "read" setup:
  
  


• Adobe announced that they've created a special Flash player that runs on the server which allows search engines to better index Flash and Flex applications: Rich Media Search. The search engines are now supposed to "see" the Flash application just as the user does. Well, that's one reason less to not use Flash ;-) Google is also improving its Flash indexing by using this new searchable SWF library.

• 12 great points you should know about WOA and REST. Note that these points are not all about technology only...
  


• Difference between WOA and SOA shortly discussed.
  


• New from Google: run your Python webapplication on their infrastructure with Google App Engine. Quite a contrast to Amazon's webservices approach S3, EC2 and SimpleDB.
  
• A status check on OpenID, including where you can get an OpenID (providers), resources and where you can use it (couple of major sites only).
