   I am some how not very comfortable with ubuntu. Its bloating with so much code that its much slower than my arch linux. But the good thing about this project is that with ubuntu, the other disributions will also try their hands on smartphon

    I wanted to ask this question regarding big O notation. When we say f(n) = O(g(n)) all we mean to say is that f(n) <= c(g(n)) with other constraints. My question is, why do we have an equal to sign, why is f(n) equal to O(g(n)).. they c

    As the documentation says, all the processing from physical to protocol layers is done by the PC. Could anyone experienced in wireless technologies explain what is the software radio frontend worth 2000$ actually doing?

    No doubt he is a genius, but what has made him excel is discipline. Try to look at the documentation of the tools that he created for this project, you will understand what I mean :)
