Knowing a little bit about this, a 12km spool of 0.125mm plastic fibre costs about $1k [0]. Limits the range still (especially if the fibre is jacketed/supported in anyway). They'll be back to barrage balloons next [1]. [0] http

The usual answer to that is that small websites who make far less money and have massively fewer resources managed to treat their users like humans. But, of course, Facebook users are not the customers (those are the advertisers) - here, th

I do have to wonder how many agonising layers of review this went through with the marketing and legal departments as part of shifting the blame. If you want to decide which OS/distros to avoid for critical stuff, look to see who'

Somewhat with you on this one, I assumed the title was YC (being big tech) were upping their lobbying game - it was after reading it that I came to your point of view.

DCF77 is a natural for this because it already includes a phase-modulated signal (as well as the 1bps amplitude-modulation). At the moment it's a 512-bit pseudo random sequence, but could obviously carry a data stream instead.

In fact there are lower-frequency signals that carry more data, generally used for submarine communication - the wikipedia article says "uo tp 300bps" using VLF (30KHz or so). Fun fact: sound cards in PC's are now fast enough

Radio 4 is particularly interesting, as it carries additional 25bps data [0] using for radio teleswitch operation [1] - a service whose days are numbered. Quite fun to receive this signal, as it's trivial to build a 198KHz receiver and
