I continue having fun “kicking the tires.” I do wish that I had a completely local Wave robot development environment, but I expect that will be forthcoming. The edit, compile, run cycle takes a while because I need to:

• Modify robot code
• Build and upload the code to Java AppEngine
• Create new test waves, invite the robot, etc.

The development cycle for Gadgets is quicker if you can simply remotely edit a Gadget XML file on whatever server you use to publish it.

I am having a bit of an AppEngine performance issue. I am used to being able to cache (reasonably) static data in memory (loaded from JAR files in WEB-INF/lib). With AppEngine your web app can run on any server and web app startup time should be very quick (and doing on-startup data loading into memory from JAR files is not quick). I am not so happy doing this, but I may keep frequently used static data in the data store. I don’t think that using JCache + memcached is an option because if I look up a key and it is not in memcached I don’t know if the key is not defined or if the key has expired from memcached.
