Comment Analog baby monitors or CB? (Score 1) 109

Analogue baby monitors transmit and receives on CB frequencies or nearby. So everyone with a short wave radio or a CB rig could listen, an if the propagation is strong, signals from hundreds of kilometers away could be received by the baby monitor, and every trucker nearby could eavesdrop in your home.
Nobody cares less about this problems and buys these, because are cheap, ruggend and consumes low power.

Comment Mesh networking (Score 5, Informative) 141

When a disaster happen, that disrupts communications, the amatueur radio operators give help even in 2015 when cellphones are ubiquitous. This runs down on some peculiar aspect of the hobby:
  • amateur radio operators are traind and know how they gear works so they can repairo or adapt the system to work, for instance a spool of wire, a fishrod and and some coax cable could be use to make a temporary antenna
  • old, proven, patent free analogue and digital transmission modes: old tube radios could interoperate with new and shiny software defined radios
  • reliability: some ham radios are built like a tank, because were designed to be used in a tank
  • almost standardized power suppy permits to power the radio with flexibility even with a bunch of D cells or a lead-acid battery
  • mesh networking: no central control system: all communications are set up freely an could reconfigure on the fly

When I was 7 years old, I was wandering through the woods, looking under rocks for creepy crawlies, playing hide-and-seek, and playing baseball with my brother and cousins. Not only did it *not* set me back in anyway, but it is some of my fondest memories of being a child.

Let kids be kids for goodness sake.

When I was 7 years oold the only computer I've seen were the ones on books or on sci-fi tv serials, that I watched on a black-and-white televison, with only two programmes that started at 5 pm. I wandered in the woods or went to the library to read. I remember that when I was a niner I visited a fair, there was a Commodore dealer. I stayed all the afternoon watching these machines and typing on the keyboards. Not that changed by child attitude. By the way I think that a Raspberry PI with mouse and keyboard could be a nice test to see if a kid is interested on programming.

Ok, if I don'actually own a car i have now some legal ways to rent a car. I could use an operative leasing and at the end of the leasing period refuse to pay the release fee and leave the old car at the leasing company. Or I could go to car rental services like Avis or Hetz. Or I could use newer rental services like Car2Go. Finally I could decide to use a Taxi. I suppose that self driving cars will be almost rented in a taxi like service or with a long time rent because of civili liabilities. Actually I take every workday a sef driving metro train.

In 1990 I was listening with a long/medium wave radio the local broadcast made with BBC and other national broadcasters due the nightly ionospheric reflection. Before ADSL and ubiquitous cheap Chinese switching power supplies this was quite easy. I also remember that there were analogue UHF repeaters in Italy for Antenne 2 and Swiss television. Tele Monte Carlo had both an Italian and a French channel. I remember that in the '94 Tele Monte Carlo transmitted the football world cup side by side by Rai, and nobody complained too much. Personally I think that those powerful interest group had been nurtured by the broadcasters that bended over their requests. The problem for national public broadcaster could be an harmonized European TV licensing covering all national broadcasters.

The world should introduce trade-sanctions against the USA and the UK, until they stop attacking other countries, and fall in line.

Naturally, it's advisable to don't sign commercial treaties with USA and UK, that are tre inverse of trade sanctions. I think governments must abandon TTIP and TPP at their destiny.
