Satellites

I learned about SatNOGS via the HamRadio 360 Hamvention Day 1 Review. SatNOGS is:
"a global management interface to facilitate multiple ground station operations remotely. An observer is able to take advantage of the full network of SatNOGS ground stations around the world. It's part of the SatNOGS project."
And speaking of satellites, this is a cool visualization of stuff in space (via @InfoSec208).

Drones

Drones:
"Smartphones sales are cooling, tablets are sinking, and PCs are stagnant — but demand for drones just keeps on growing. As this chart from Statista shows, consumer drone sales in the US have increased sharply over the past few years, and are expected to keep growing."
And you won't have to register them with the FAA anymore.

Doom!

It's everywhere!

Compaq

I enjoyed listening to the How I Built This story about Compaq. We ran a lot of Compaq hardware back in the day, but I really didn't understand the bigger picture of what was going on. I did like my 575 desktops!

Refurb Amazon Echo Dot - $38

You can get a refurb Amazon Echo Dot for $38.

But don't do it... it is a slippery slope. I've got voice control of my thermostats. I added two plugs to control a couple of outlets last week. Now, I'm looking for a deal on light switches.

Princess Leia shared "Death Star Plans" with you

I've also thought that 99% of the plot driving problems from Seinfeld would be eliminated if they had mobile phones.

PSA: Don't Buy an Amazon Echo Dot

Don't buy an Amazon Echo Dot. It is a gateway drug. Now I want to buy Alexa-enabled outlets and switches. And maybe I need this battery pack, so I can move the Dot from room to room with me.

It'll cost me a few bucks up front and it will be great when it works. It also means, invariably at some point, I'll have to troubleshoot something that never fails like an outlet or light switch.

Zero, One, or Infinity

An interesting tidbit from a NANOG/DNS post:
"But needing “multiple” DNS Root Zone Servers and coming up with the number 13 appears to be somewhat curious. It seems such an odd limitation in the number of root servers given that a common rule of thumb in computer software design is Willem van der Poel’s Zero, One or Infinity Rule, which states a principle that either an action or resource should not be permitted (zero), should happen uniquely (one) or have no arbitrary limit at all (infinity). For root servers, it appears that we would like more than one root server. But why set that number to 13?"
Leading to:
"The desire in the design of the DNS priming query and response was to provide the longest possible list of root name servers and addresses in the priming response, but at the same time ensure that the response was capable of being passed in the DNS using UDP. The largest possible set of names that could be packed in a 512 octet DNS response in this manner was 13 such names and their IPv4 addresses - so there are at most 13 distinct root name servers to comply with this limit."

Amazon Echo Dot

I resisted buying an iPad for a long time, because I wasn't sure how much we would use it. I'm quite certain we've gotten our moneys worth and more out of the iPad 2 over the years.

Likewise, I'm wondering if the Amazon Alexa voice activated personal assistant service would prove to be a good value over time. I really didn't want to pony up $180 for the Amazon Echo to try it out.

With the Amazon Echo Dot, I can dip my toes for only $50, so that makes it a little more tempting.

(If you wanted to really commit, you can buy 5 get 1 free or buy 10 and get 2 free with codes DOT6PACK or DOT12PACK.)
