Build your own time server with a GPS receiver.

Nov 24 2018

If you've had your ear to the ground lately, you might have heard that the NIST timekeeping radio station used by devices all over the world as a time reference for Coordinated Universal Time as well as some experiments in signal propagation and geophysical event notices might be on the chopping block in 2019, leaving the HF bands quieter and, let's face it, we can't have nice things.  Clocks that rely on this time source signal won't have any way to stay in sync and the inevitable drift due to the imperfections in everything will cause fractions of second to be lost and a fresh outbreak of kinetic pattern baldness.  The ultimate effects of this latest bit of clueless petulance on the part of Donald Trump remain to be seen, but it seems likely that this isn't a sexy enough problem to catch brainshare like Y2k did.  If you work extensively with computers chances are you're not that worried because your machines use NTP - the Network Time Protocol - to synch their internal clocks with a known time reference server on the Net someplace.  Something to consider, however, is whether or not your upstream tier-one and tier-two time sources are actually using the NIST WWV time singnals as their reference signals.  There is, however, a nifty way around this: Build your own NTP server that uses a reference time source that can't be shut off as a source, the Global Positioning System.

First, I'll show you how to build your own GPS time server, and then I'll explain why it works.

Those who do not learn history are doomed to repeat it.

It seems there is no end to the number of quotes through history that go something like this: "Those who do not remember history are doomed to repeat it." It's been variously attributed to Edmund Burke, Sara Shepard, Santayana... this is not to say that there is no truth to it. Far from it.

I haven't said much about the election of 2016, in part because my personal life has been upside down and inside out for weeks now, in part due to work, and in part due to the fact that there is so much fucked up stuff going on in the United States, in the global media, and in part in many different communities. When you factor in the fact that fake news is not just a propaganda tactic, it's a growth industry, the time requred to research even the simplest article is prohibitive. Pro-trolls and trollbots on pretty much every social media network don't make things any easier.

Maybe that's the point.

I'm certainly not the only person to notice that the media manipulation happening in 2016 isn't using new strategies or tactics even though they're being used on the Net in addition to print media and television. That people are treating this as a wholly novel phenomen, unprecedented in the western world has been driving me nuts. Did nobody pay attention in history class?

Then I got to thinking...
