Why I haven't tried this when I studied 555 timer

It always a good idea to connect output to a speaker to get the feeling that what actually the device do in reality.
Usually we connect the output to  CRO in our college labs, But I feel its always a good idea to take the output to a speaker in your own experiments labs.
The Sine waves you see in the CRO gives you experimental results,but if you need to feel electronics it always good to connect the outputs to some display or speaker kind of devices.

Hadoop Tutorial 1 - What is Hadoop?

One of the advantage of Social networking website is  they helps to promote new technologies even though its their need.

 

 Apache Hadoop is an open-source software framework for distributed storage and distributed processing of Big Data on clusters of commodity hardware. Its Hadoop Distributed File System (HDFS) splits files into large blocks (default 64MB or 128MB) and distributes the blocks amongst the nodes in the cluster. For processing the data, the Hadoop Map/Reduce ships code (specifically Jar files) to the nodes that have the required data, and the nodes then process the data in parallel.
