signals

That spectrum shortage isn't stopping AT&T's newly launched LTE network for delivering some smoking speeds according to tests out from Signals Research this weekend.

AT&T, which launched LTE in in five cities Sunday delivered LTE speeds averaging 23.6 Mbps down and 15.2 Mbps up.

Almost every video product these days will convert standard-definition signals to HD, but how?

Bashshell.net: "When a process receives a signal, that process must respond to the signal. Uncaught signals will cause default actions to take place, which often means the process is terminated."

The Register: "Developers of the Linux kernel have patched a bug that allowed attackers to remotely crash a machine by sending it malicious Wi-Fi signals"

A true wizard doesn't just run processes, a true wizard knows how to communicate with those processes through signals to stop, restart, and even kill processes.

This may sound like arcane and obscure knowledge, but if you follow along, you'll be managing your processes like an adept in no time.
