I know of the Array.uniq method in ruby which ret...

Why Object[].class.isAssignableFrom(String[].class) == true ?
Why is Object[].class.isAssignableFrom(String[].class) == true, while String[].getSuperClass() or getGenericInterfaces() could not get Object[]? I checked the source of JDK, but i don't think i can get the answer myself. For now, I know JDK uses tree to store the relationship between Classes, and depth to indicate its level, Class::isAs...

Technique for determining if an integer sequence can be generated without branches?
If you're optimizing for an architecture on which branching is expensive (say the PS3's cell processor), it can be important to be able to determine whether or not you can express a given algorithm without using branches or at least using fewer branches. One pattern that I see a lot in unoptimized code is a bunch of if's used to tweak a...
