I only know of Arch Linux which is pretty awesome and I use it for my desktop. But its rolling release model makes me wary of using it for servers. I know that the benefit of an optimized distribution will not be striking, at least it is unlikely to hurt. Given that I have more modern CPU I would rather enjoy an occasional benefit rather...
So * by itself means repeat the previous item zero or more times. The output of * is nothing. What about **? This gives an output, but how does matching zero or more times of nothing give something? Could you also explain that please? Same for ?*: Nothing precedes ?, so that is nothing right? How does matching zero or more times of nothi...

I am new to programming, and even newer to Linux. I was told that Linux is the best OS to learning to program as it lets a programmer interface closely with the machine architecture. I heard a lot about the GNU tool-chain and that it provides the best programming environment on Linux so I decided I won't use an IDE and put in as much tim...
My webservers use the usual Java I/O with thread per connection mechanism. Nowadays, they are getting on their knees with increased user (long polling connection). However, the connections are mostly idle. While this can be solved by adding more webservers, I have been trying to do some research on the NIO implementation. I got a mixed...

The father process should read the contents of a file which name will take as an argument when you run the program. The father should send the text read to the child, which takes to convert those characters 'a' found ...

Is IO more efficient, due to the linux disk buffer cache, when storing frequently accessed python objects as separate cPickle files instead of storing all objects in one large shelf? Does the disk buffer cache operate differently in these two scenarios with respect to efficiency? There may be thousands of large files (generally around...
