SpringOne2GX - Day 1 Keynote

Brain dump of the SpringOne2GX day 1 keynote featuring Rod Johnson, Graeme Rocher, and others.

  • Major tenets of SpringSource
    • simplification
    • community
    • innovation
  • simplification
    • amount of code in Spring apps has decreased over time as the amount of code in Spring itself has increased
    • framework does more so you do less
    • nice chart showing number of lines of code in Spring sample apps over time
  • community
    • large--Gartner estimates at about 3 million developers
    • traits of community: passionate, highly skilled, think for themselves
    • get involved!
      • ask/answer questions on mailing list and forums
      • submit features and bugs to JIRA
      • participate in events (UGs, meetups, etc.)
      • start a UG or meetup in your area if there isn't one
      • contribute code
        • doesn't necessarily have to be core code--extensions, tests, plugins, etc.
  • innovation
    • everything can be improved
    • always new challenges to overcome

Spring 3.0

  • simplify configuration
  • MVC improvements
  • REST support built in
  • support for JSR-330 (DI via annotations)
  • Spring Integration -- demo
    • concept: "have Spring all the way down in your stack"


  • all about productivity
  • integration all done for you
  • more prescriptive
    • while Spring is about choice, that means more configuration
    • Grails takes away some choice, but the trade-off is increased productivity
  • Groovy/Grails state of the nation
    • huge growth in recent months--150% increase in traffic to web sites
    • Groovy 1.7 and Grails 1.2 released coming soon
    • big performance improvements in Grails 1.2
    • plugin ecosystem very healthy
      • 25 million lines of user contributed code in 300+ plugins
      • cool stuff going on with alternative persistence mechanisms (e.g. CouchDB), RIAs, etc.
      • iPhone ads: "there's an app for that" -- Grails: "there's a plugin for that"
    • Challenges
      • IDE support--gets much better with newest SpringSource Tool Suite (STS)
      • hosting/cloud -- need better support, easier deployment

Lifecycle and Tools

  • Build -> Run -> Deploy
  • tc Server developer edition -- free download
    • really nice dashboard with performance and health insight
  • Spring Insight Dashboard demo
    • real-time performance graph
    • huge amount of detail you can drill into by clicking on a request
    • links back to STS--takes you right to the relevant spot in the code
    • app health screen tracks performance by component over time
      • uses 99th percentile so you're focused on what most users are experiencing
  • SpringSource Tool Suite
    • Eclipse based
    • single download for everything, including tc server

Keys to Future

  • developers
  • simplification
  • innovation
  • community
  • SpringSource + VMWare
    • VMWare committed to community and open source
    • VMWare serious about middleware

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Setting Up Django On a Raspberry Pi

This past weekend I finally got a chance to set up one of my two Raspberry Pis to use as a Django server so I thought I'd share the steps I went through both to save someone else attempting to do this some time as well as get any feedback in case there are different/better ways to do any of this.

I'm running this from my house (URL forthcoming once I get the real Django app finalized and put on the Raspberry Pi) using I don't cover that aspect of things in this post but I'm happy to write that up as well if people are interested.

General Comments and Assumptions

Using latest Raspbian “wheezy” distro as of 1/19/2013 (’lll be using Nginx ( as the web server/proxy and Gunicorn ( as the WSGI serverI used heavily as I was creating this, so many thanks to the author of that tutorial. If you’re looking for more details on …
