ScreenToGIF is an handy tool to capture your desktop screen movement into GIF images.

The tool is a portable open source tool with very simple easy to use user interface. You can download the tool from here.

Usage is very simple. Extract the downloaded zip file and you will find an exe file in side extracted folder named ScreenToGif 1.0.exe. Execute this file and you will find a window frame on your screen. (See image below)

This post is with little higher tech hotness. Traditional Database management system are pretty good at handling data using SQL. However is you hve massive amount of data (in Terabytes) then query processing gets very time consuming unless you are having proper hardware and infrastructure.

Uncertain about term BI(Business Intelligence)? Have a look at this wikipedia definition of BI.

Still not clear about BI then don't worry. You don't need to understand BI in order to use Google fusion tables. 

Google Fusion Tables is Google's latest (okay, not that latest ... :P ) experiment on data analysis. It is handy tool to analyze your data and convert that data into meaningful form by generation charts , summaries and maps. These meaningful data makes a lot of sense. Want to learn how to make better sense out of data? Take a look at Google's online course Making sense with Google

To take more closer look at Fusion table please refer this link.

Doubts , queries are most welcome.



Yesterday I posted about Google's courses related to digital analytic. Today I would like to share one more data related course from Google. Making Sense of Data.

Again Google is giving away certificates for this course too. Although course is already started but still certificates are available till 4th April. Even after 4th April course content will be available for learning.

Jump to course: datasense.withgoogle.com/course  
Google Analytic Academy provides free online courses to learn Digital Analytic. You can access it from here.



Recently Google has launched second course under Analytic Academy. Google Analytic Platform Principles. In order to receive certificate for the same course you have to register for the same before 27th March,2014. So hurry ... 

Also this one is little advanced level course so it is commanded by Google that before going through this course you may go through first fundamental course Digital Analytics Fundamentals


Recently I wanted to do some Java programming on client's Virtual Machine. As the speed of VM is very slow I was hunting for so
me lightweight development tool. Moreover I needed a portable tool which could be executed without installation as I wasn't having installation right on VM. So I found several lightweight alternatives for Java Development. The list is as follows:
There are many more. I explored few of these tools. Personally I would rate JCreator at the top. But JCreator is not a freeware and also it is available only for windows platforms. Although light version of JCreator is free to use for academic purpose. You can check JCreator licencing information from here.

JCreator Screenshot

As I was looking for a portable tool, I choose DrJava which is portable and also java based so it is platform independent and also freeware and Opensource.

If you are having more suggestions for Java tools then shoot in comment area... :D
