So many technologies you'll be buzzin'.  This article will briefly summarize the meeting and the technologies mentioned.

So the Silicon Valley Java User's Group had a great meeting on January 18th at the Googleplex.  It was on a fairly advanced topic, Heroku.  James Ward delivered it and delivered it well, it was a whirlwind tour-de-force of a microcosm of Java and other technologies.  Heroku itself was described as PaaS, Cloud + Polyglot and in the course of the session, many, many other buzzwords (it wasn't really "buzz" in that it was actual informative content and not empty hype) and technologies were mentioned.  So many that they need some explanation and so many explanations that they need categories.

• Heroku
• Upload via Git
• WAR Optional
• Slug
• "Slug are compressed packages optimized for lightning-fast distribution across the dyno grid."
• Dyno
• "a single process of any type running on the Heroku platform"
• Dyno-Hour
• A Dyno running for one hour, the unit of billing
• Multiple Build Tools Supported
• Erlang HttpServer
• Addons
• Other DBs, additional features, etc.
• May have separate charges
• Performance
• Performance can be monitored with several Addons, including New Relic (see below)
• Play Framework
• Java WebApp Framework
• Play2
• Languages
• Polyglot
• Not a language itself, but the ability to understand many languages
• i.e. Hiroku can have many different languages deployed to it
• Java
• JavaScript
• CoffeeScript

• Ruby
• Ruby on Rails
• Grails
• Groovy
• Scala
• Akka

• PaaS
• Platform As A Service
• CLI
• Command Line Interface

• API
• CRUD
• HTTP
• Statelessness
• SBT
• Scala Build Tool (see below)
• DSLs

• Sticky Sessions
• None in Heroku
• Session Management
• State to JavaScript or NoSQL store
• Web Container can do automatically

  • JQuery
  • A JavaScript library that started as a way to query the DOM, but grew from there
  • Finagle
  • Asynchronous RPC library
  • NIO
  • New I/O
  • Supposed to be better than traditional (Java) I/O calls
  • Blue Eyes
  • Web 3.0 framework for Scala
• Dependency & Build Managers
• Ivy

• Scala Build Tool (SBT)
• A scala-specific build manager
• Other PaaSs
• Google App Engine
• Amazon EC2
• Other Technologies
• Spring Roo
• A rapid application development tool
• Has a CLI
• Git
• Git Remote
• This is basically another git repository that you pull / push code to
• Git End-Point
• Git isn't my thing, comments anyone?
• Selenium
• Web browser automation, great for reproducing an error
• The API is similar to HttpUnit
• Open JDK
• An implementation of the Java specification
• New Relic
• A web performance tool
• Superficially reminds me of DynaTrace
• Tag Lib / Tag Libraries
• These are reusable tags for xml (including xhtml)
• Basically, a way to define your own tags for reuse
• JSON
• An easy way to transfer objects as text



This firehose fail from failblog.org.

• The JS stands for JavaScript, but is language independent
• Futures
• A language construct that aids in synchronizing computation
• Other
  • Stack Overflow
  • Google recruits are active here

I hope that you enjoy drinking from the fire hose!  You definitely will if you need to ramp-up on these things.  I hope you found some use here or followed some of the links.  At the very least if you were already familiar with the 80 technologies listed (YES!  EIGHTY!) then you deserve a pat on the back (and probably a hefty salary!)
