  Simple explanation about process and thread

Process and thread are two basic concepts of operating system, but they are a bit abstract which cannot be  mastered easily. There is an analogy which explains these concepts very well. 1. The kernel of the computer is CPU, it handles all the computing tasks, it's like a factory and will run all the time. 2. Assume there is power limitation for the factory, it can only supply to one unit once,i.e, when one unit is working, other units must stop and wait. The meaning behind this is that eac...

  How small should a function be?

"The well-designed functions are often relatively small, large function design is often a mess or there is a lot of room for optimization."Maybe you think there is no need to discuss the size of functions, because the nature of the function design is cohesive, its size is only its manifestations. But it is necessary to discuss about the size of function because the statement above .First let's understand the concept of minimum code processing unit : a basic operation (assignment, comparison, etc...

In other words, how are you different from who you were a decade ago and how will you be better than who you are now a decade later?In my opinion, a programmer, regardless of his work, should improve himself in three aspect...

  TIOBE : No news today

TIOBE released the programming index for September 2012. There is no big change for this month compared to last month, the top 3 are still C, Java and Objective-C. In top 20, only Transact-SQL exchanged the position with VB.NET. Java shows trend of drop, will it be worse because of the ignorance of Java's vulnerabilities by Oracle. This index shows that the programing lnaguage market is quite normal, no big events. Except Objective-C, in recent years there are no other new languages which have b...
