Story Time: Fun with crazy people

A while ago, I was on a project where we were working with another division the company, and were using 3rd party GIS products to sync up our data.  We were setting up a demonstration, and were on a telcon during the setup.  I had no problem getting the GIS product to communicate to the master database, but the other division was having issues.

Initially, they thought that my system was interrupting theirs.  So, I unplugged the network cable from my machine.  Still, their problem persisted. Then it got weird.
They asked me to unplug the power of my machine. When I asked why, they said that I might have been using Ethernet over power, to which I replied that there was no way this stock cheap machine was equipped with that specialty hardware, it was just a regular old power cable. Despite this, they insisted that was the problem.

So, I did what any sane person would do, and just told them over the telcon that I had unplugged the power of the machine, instead leaving it plugged in and on, but still disconnected from the network. And of course, after I told them it was unplugged, their problem mysteriously vanished.  I still don't know what the problem was. I assume that it was probably something silly and they didn't want to look foolish on the call. 

Android Studio first impressions

I started playing around with Google's new product, Android Studio (currently version 0.20).  Previously, the provided a plug-in for Eclipse to assist in Android development.  The new tool is based in the IntelliJ IDE.

The integration with IntelliJ is a lot nicer than the previous integration with Eclipse. For one, it's just one download, instead of having to get Eclipse and the ADT separately. They provide some handy wizards to get you started as well.

I tested Android Studio out by crafting a small note-taking app.  I used their blank layout template, and just ran from there.  The GUI editor is much improved from what I remember the Eclipse version having.  It's approaching Visual Studio in style, especially in being able to assign method as the click handlers for buttons.  This makes it a little easier on the developer.

Running in emulation is relatively painless, and they include a good number of template VM's to try.  Granted, the VM's can still take a while to load even on a good workstation, but the overall creating and VM and launching is simple enough. 

Overall, I look forward to playing around more with the IDE. It's nice having a more fully integrated environment, and it'll be interesting to see what other features they add.

More GWT Thoughts

One of the really nice parts about GWT is their GWT RPC (Remote Procedure Call) interface.  It functions similar to RMI in Java, where you define methods on an interface, and just extend  the RemoteService interface.  For example:

public interface SampleInterface extends RemoteService
{
    public void myMethod();

}

You end up requiring an Async interface as well, that takes a callback as one of the parameters, but the GWT plugin for Eclipse will actually generate that for you, and prompt for changes to methods in one or the other if the method signature changes.
 
So, you get all of your handler code in a method, that's able to be called directly, without invoking any lengthy servlet strings directly.  It's extremely nice.
