What is Apache Cassandra?
Its a no sql database which is mainly used to storing Big data. It famous for its Fault tolerance ,scalability, availability and Performance. Its used by Facebook ,ebay , Go-daddy and other popular companies.
One of the largest production deployments consists of over 15,000 nodes storing over 4 PB of data. Other large Cassandra installations include Netflix (2,500 nodes, 420 TB, over 1 trillion requests per day), Chinese search engine Easou (270 nodes, 300 TB, over 800 million reqests per day), and eBay (over 100 nodes, 250 TB).

Source Control management System free- Configuration Management system free
What is CMS?
CMS is meant for configuration management system which mainly used to control the Source Code.
Why we need CMS?
Consider an organisation like Microsoft has 1000's of projects going on or Let us consider designing an Airway Reservation system which involves lot of modules and lot of coding. 100's of employees will be working on the code globally . There s need of system which can control the code changes by employees for that module.
CMS make sure that no two person work on same code. It has a concept called check in and check out.
It uses one central repository (storage) and initial project will be pushed to that . Every one takes the update from the central repository and starts working on it. If Person A and Person B are working on file named FILE 1 then CMS plays vital role.
Scenario :
With out CMS
Person A acquired the FILE 1 and started modifying . Consider Person B also want to change something in the same file same be same method what A is changing. When both are changing . they dont know each other about the changes. Finally a weird file will be created. If its in same office, no problem . Imagine A is in India and B is USA.
With CMS
According to CMS, Person A can check out the File from central repo. If B wants to modify something , he has to take update or he modify something and about to check in to repo . He will be thrown an exception stating that Person A is already checked out the file and modified something . As Person B is notified , he will wait till A change updates then B can check the changes and incorporate if any needed.
This is what called Source Control Management system / Version Control Management System /Configuration Management System
Tools
Open Source
> Git Hub is the best source control management system.
Closed Source
> SVN Tortoise
> VSS (Visual source safe)
> a lot more..... (just google it)
GitHub is world famous source control system. it's used by top class IT companies like Facebook and Open source geeks

Side Effects of Protein -Whey-Isolate vs Concentrate
What is Whey?
Whey is a form of Protein extracted in the process of making cheese from milk. The Liquid form is dried to make Whey protein . Its the Concentrate form.
What is Whey Isolate?
Whey Isolate is the extracted form from Whey Concentrate. A machinery is used to remove the other components like Fat ,Carbohydrates and leave only protein. Its the Purest form and contains around 85-95% of protein. Its good for building lean muscle.
What is Whey Concentrate?
Whey Concentrate is the first step of protein arrived from the extraction process. It contains Fat, Lactose,Carbo and higher amounts of protein. Protein percentage is about 75-80%. Its good for health as you are getting other components to your body.
Isolate Vs Concentrate
Isolate is further extracted part of concentrate. so that's the reason its price is double compared to concentrate. I personally feel Concentrate is better as it contains other form of components needed for our body . If you are solely interested in body building and interested in purest protein taking , you can go a head with Isolate .
Take More water to control protein in take
Side Effects of Protein
> Excessive intake of anything bad for health.
> Take Limited protein and control it by taking more water.
> One should take >= gm/ 1 lb (weight in pounds)
Ex: A person with 60 kgs = > 60 * 2.2 =>132 lb
So one should take 130 gm/ day
Control it by taking more Water.
