All writes that go to the same block ID are considered overwrite (write over the same place).
However, duplicate writes are writes that have the same content, they may go to the same block, or they may not.
So, we cannot conclude the number of overwrites is greater than the number of duplicate writes, or the other way around. Generally, it’s much harder to identify duplicate writes than overwrites, because detecting content duplication requires manipulating a much larger amount of data.

I’m sure many of you love the little robot named “Wall-E”, from the Hollywood movie of the same name. How about a Wall-E of your own? Wouldn’t that be cool?
So astonishing, someone made a Wall-E, completely DIY. And this Wall-E is a working computer! Following are two pictures of this masterpiece.

The following description briefly tells the uses of the two models.
Finite automata and their probabilistic counterpart Markov chains are useful tools when we are attempting to recognize patterns in data. These devices are used in speech processing and in optical character recognition. Markov chains have even been used to model and predict price changes in financial markets.

I have always been wondering why multicore is such a hot topic nowadays. Since the advent of this architecture, all big players have switched their assembly lines to produce this new chip. As a matter of fact, multicore is inevitable in the future. I guess we have to adapt to it, since we have no other options.
