kernel

I know that UDP is inherently unreliable, but when connecting to localhost I would expect the kernel handles the connection differently since everything can be handled internally. So in this special case, is UDP considered a reliable protocol, or will the kernel still potentially junk some packets if buffers are overrun?

Is there a way to receive receive data as unsugned char over UDP on QT

Why does my laptop resume immediately after suspend?

What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
