Could someone take the time to explain me the language underpinnings here : int foo = myObject.SomeList.Count; for (int i = 0 ; i < foo ; i++) { myObject.SomeList.Add(bar); } goes into an infinite loop because foo references a value that keeps being incremented. Modifying the first line to: int foo = (int)myObject.SomeList.Count; ...

It seems the value of most technology has depreciated to 'nothing.' Is it that the cost of developing supposed "technology" has been drastically lowered to where it is a commodity for the taking? Is it that the sum of all human knowledge is now readily available for study (Internet)? The software I write at work seems to be valuable i...
