Comment Re:Whatever happened to comm lasers? (Score 1) 64

Lasers between the continents is too impractical. Combine tropospheric scatter and enough ships, you might be able to build a microwave relay system, but the cost would be horrendous and obviously extremely vulnerable to enemy action. If you are wondering what I'm imagining, think multiple White Alice type links across the Atlantic.

You are partially correct. Any time you increase frequency significantly, amplifier efficiency drops. Innovations in semiconductor technology will help though. The other issue is the change in modulation techniques and the digital processing required to handle the new modulation techniques. This also consumes a lot of power. This will reduce significantly as the technology progresses.

Comment I've known about this for years (Score 1) 112

There were some low end (possibly toy) electronic organizers that had a 1-way sync that worked via either flashing keyboard LEDs or the monitor. This keyboard LED vulnerability dates back to the IBM AT which was the first IBM PC to have the ability to change the Caps/Num/Scroll lock state.

Apple Watch does in fact play a ringtone, if you use Do Not Distub mode Apple Watch follows iPhone, if you use the silent switch, both devices need silenced individually. Last meeting I was in, I switched on Do Not Disturb (both Apple Watch and iPhone) and theater mode on Apple Watch (keeps the display from turning on unless you touch the screen or press a button).

Charter should refuse to sell the system and simply shut the thing off and pay all the applicable FCC fines and tell New York to suck it. The government has been over regulating wireline communications since the 1980s. BRING BACK THE BELL SYSTEM!
