We are stuck with technology when what we really want is just stuff that works.

Albert Einstein

It has become appallingly obvious that our technology has exceeded our humanity.

Jose Manuel Rodriguez Delgado

Can you avoid knowledge? You cannot! Can you avoid technology? You cannot! Things are going to go ahead in spite of ethics, in spite of your personal beliefs, in spite of everything

Sergey Brin

Technology is an inherent democratizer. Because of the evolution of hardware and software, you’re able to scale up almost anything. It means that in our lifetime everyone may have tools of equal power.

Douglas Adams

Most of the time spent wrestling with technologies that don't quite work yet is just not worth it for end users, however much fun it is for nerds.

What is the dBm or dBmW

A unit of measure used to reference signal strength level. unlike dB, this is relative measure, dBm is an absolute measure.

dBm ( Decibel-milliwatts ) or dBmW is a short from for the power ratio in decibels (dB) of the measured power referenced to one milli watt (mW). Most communication systems human speech, microwave and fiber optic networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form. The baseline reference relationship is 1mW = 0 dBm. A doubling of signal power yields an increase of approximately 3 dBm eg: (2mW = 3 dBm).
