• C - How to implement Set data structure?

  - by psihodelia

  Is there any tricky way to implement a set data structure (a collection of unique values) in C? All elements in a set will be of the same type and there is a huge RAM memory.

• Does Table.InsertOnSubmit create a copy of the original table?

  - by Bryan

  Using InsertOnSubmit seems to have some memory overhead. I have a System.Data.Linq.Table<User> table. When I do table.InsertOnSubmit(user) and then int count = table.Count(), the memory usage of my application increases by roughly the size of the User table, but the count is the number of items before user was inserted. So I'm guess…

• Why do exceptions usually have the suffix 'Exception' in the class name?

  It seems to me that it is rendundant information as the usage of the class will make it apparent that it is an exception. Furthermore, in PHP, the class must extend the Exception class so it will be apparent that it is an exception when looking at the class on its own. Despite this, developers usually apply the…

• What's the difference between reserved and committed memory?

  - by glutz78

  I understand that memory has to be reserved before being committed. And when it's reserved, no other process can use it. However reserved memory does not count against available RAM. But shouldn't it? Because if no one else can use it, then what good is it being "available"? Or is there some bigger difference?
