What makes Scala's operator overloading “good”, but C++'s “bad”?
...la's flexible method naming which, IMHO, make Scala both less abusable and more abusable.
In C++ the only way to get in-fix notation is using operators. Otherwise you must use object.message(argument) or pointer->messsage(argument) or function(argument1, argument2). So if you want a certain DS...
Increasing the maximum number of TCP/IP connections in Linux
...eout = 60
This basically means your system cannot consistently guarantee more than (61000 - 32768) / 60 = 470 sockets per second. If you are not happy with that, you could begin with increasing the port_range. Setting the range to 15000 61000 is pretty common these days. You could further increase...
