I found some developers have complained that enterprise level development take longer compilation and that has become an issue among many developers where length of debugging has increased. Just to show what exactly I am talking about, I have copy pasted the simple compilation of GWT MyWebApp Application.

But there are ways of working around. You can reduce the compilation just to compile for one browser. In my opinion is this can be done by using package/modularization (java package structure) with the help of ant to do the build process. But this article is not to talk about use of ant of java package structure.

By default GWT get compiled to support following browsers.

ie6
ie8
gecko
gecko1_8
safari
opera

Do we really need all these browser during the development time. I think thats a personal call but when I develop something I hate to wait the compiler to run for super long time. If thats the case for all of you here is the solution. I would also like to bring up another aspect on reducing compile time during development. Imagine our small application (MyWebApp) is not as small as we think and we support multiple locals. In this case to support all the browsers we have to compile the application in the default mode. Just to make this argument lets say we support 10 locals.

Here is the calculation for compile time: 36.654s * 10 = 366.54s this is fine when a build master is doing production build. But as a developer I would like to do a quick build and see my changes.

this is the file that you need to change to get different permutations.

this file come in handy if you want to separate the project into multiple modules or rename the module to make the module name shorter. To reduce the number of permutations or to build the application just for one browser, we need to tell the compiler to do so by using this file.

Module xml file(s) are located on the java class path and they are always referred by their logical names. So let say you are going to develop an application call MyWebApp, and you own the “boo” domain then you can find this xml file in com.boo.mywebapp under the name of MyWebApp.gwt.xml

by default you have set it up to compile for all the browser and it should look like this or something similar to this.

To reduce the compiler to do only one permutation you just have to pick a browser that you would like to do the development and add that as a property value, in this case we use the user.agent property and set the value to gecko1_8 which is firefox

here is the *.gwt.xml file looks like after adding the property value.

Lets see if this really reduced the compilation time.

Sure it did, and you can also see that it only did one permutation. Similar approach can be taken to locale where you define the local you want to compile with.

Anyway, Some Gmail users have filed a law suit against Google Buzz concerning its privacy. I thought entire point of Buzz is to be public and if you are so concern about it you should simply ignore the buzz and not participate in it. But I am also not happy how Google has been tapping into private data streams such as open networks while they capture street views. Just because you are the giant in the search industry you don’t get to do what ever you think. Remember great power comes with great responsibility.

I checked to see any of my voice messages are showing up on results page fortunately it didn’t, and this made me think twice continuing with the Google Voice account.

Bing Travel Prediction

Note that deals are compiled on yesterday’s lowest airfares and can change often.

but its still ahead Google at least on this matter.

Not only that it gives nice graphical representation of the price fluctuation along with the prediction of the price with respect the date.

So, its True that this is no ordinary search engine, but Machine Learning at its best. So if I was Google I would be bit worried about bing. Google as new era technology company had the advantage of learning from all the mistakes made my giants like Microsoft, Yahoo, etc. But I guess for the first time, Microsoft using it potential and capability and thinking out of the box. And the best thing is they are simply try to match everything that Google does where they have been doing it for the past decade. I am not a big Microsoft fan but I have to give props for this to Microsoft, Bravo.

Gmail out of Beta

But Today, I saw something different, when I logged in No Beta sign along with the Google Gmail Logo, I thought something wrong. But it was same for my calendar so looks like Google has finally out of its Beta cave.
