4. 1.0Written in 2 weekendsPUZ file format sucksLots of UI issuesGridView performance poorGridView/ListView have two completely different interaction modelsHowever, “Good Enough for Me.”

5. 2.0Laptop stolenWritten in about 3 weeks of nights/weekendsNew UICustom renderingCustom touch handling (ugh)Cleaner CodeIO, State, Controller in separate APIs.

6. Life is GoodIn a reasonable steady stateGood feedback from usersGrowing if small user base

7. Other PeopleGot an email from Pam @ Google asking for a Wave versionGot an IM from Josh @ Palm asking for a WebOS version

8. Hmm…“Some people when faced with a problem think, I know, I’ll use GWT…”

9. Initial EffortCode reuse actually made this easy.Moved model code and IO code into separate packages.Made GWT Module for original codeImplemented new renderer for webTook about 5 hours to get something playable

10. History RepeatingPlay -> Render cycle painfully slow on the DOM.Re-implemented the Web version to look more like the original Android version with MVC and bind eventsPerformance problem solved

11. ProductivityWeb version (after Android code)About 16 hoursFacebook Version About 3 hours (Still needs work)WebOS VersionAbout 5 hoursBinary IO painfuliGoogle versionTrivial

12. Productivity (cont)Wave VersionAlmost 40 hoursWave development is a serious PITA because you need a full deploy to make it work. There are a lot of things they don’t tell you in the docs.

13. SummaryJava on “Everything but the Java Platform”Tips:Manage Dependencies.Gin is totally frackingawesome.Interesting:GWT gziped is ~ same size as Android version.
