  1. Thanks for the informative show guys, really enjoying the content.

    Have you all checked out Kotlin? I've only been using it for a little while, but it's been a lot of fun so far. It removes a lot of the boilerplate code that was aggravating as a Java developer, but still gives 100% access to all my existing Java code.

  3. Freddy, you should update your profile! Haven't you been saying on the podcast that you work for Expedia now?

    1. Golly yes! time flies! Thanks for the catch!

  4. Freddy, I'm using pocket casts for Android. I found Java pub house through this app, I'm not seeing Java off though.

    1. java off-heap should be there, if not, javaoffheap.com would do the trick (there is an rss feed in there :)
