Kids can use a simple programming language to play interactive games with Play-i's two robots to get a rudimentary knowledge of programming. Article | Michelle Goodman2011 years, Vikas Gupta the first time in his life as a father. He began to think about how old his daughter could start learning computer programming. Through observation and research, Gupta found that if children had an interactive physical toy, they could understand the concept of programming when they were 5〜6 years old. He also found that there are few toys in the U.S. market that teach children programming skills ...

MapReduce is a distributed programming model developed by Google for mass data processing in large-scale groups. It implements two functions: map applies a function to all members of the collection, and then returns a result set based on this processing. and reduce is the classification and generalization of result sets that are processed in parallel by multiple threads, processes, or stand-alone systems from two or more maps. The Map () and Reduce () two functions may run in parallel, even if not in the same system ...
