To be honest, as a kid I enjoyed chess and played with my friends right up to the point where you suddenly had to start memorizing openings and other canned sequences. At which point it felt more like a school subject than an escape from it.
I might just be lazy, and 151 is a reasonable-size prime number
Because now I know it's 151 digits. Had no idea before.
How can you know I didn't just guess?
Here is the number of legal positions:

I'm not quite clear how 6.697231142888292128 927401888417065435 099377806401787328 103183376969456244 285472181052143260 127743713971848488 909701118362834704 688128279071499265 02347633e151 is much of an improvement, to be honest.
You have the Part 15 and ISM services for that. You really can buy a microwave link that's metropolitan-distance and legal to use.
We lost much of our 440 capability to PAVE PAWS in California. Remember, Amateur Radio is not the primary service on many bands. The military is on 440.
If you want that nearly infinite microwave spectrum, you have the Part 15 and ISM services. Absolutely nothing is stopping you. Power is not the issue with those frequencies, it's line of sight and Fresnel zones.
No, I absolutely do not have to prefix my words with anything. You do that by posting as an anonymous coward. I use my real name to indicate that I stand behind my words.
Yes. The usual mechanism here would be WiFi security, with HTTPS or SSL inside of it.
OK, no real technical data and some absurd claims here.
First all-digital transceiver? No. There have been others. Especially if you allow them to have a DAC and an ADC and no other components in the analog domain, but even without that, there are lots of IoT-class radios with direct-to-digital detectors and digital outputs directly to the antenna. You might have one in your car remote (mine is two-way).
And they have to use patented algorithms? Everybody else can get along with well-known technology old enough that any applicable patents are long expired.
It would be nicer if there was some information about what they are actually doing. If they really have patented it, there's no reason to hold back.
Smart article yes, but it's still incredibly stupid to buy a lottery ticket.
Unless you think it's fun to play. Idle daydreaming about what you'd do if you won; the excitement as the numbers are called; the rollercoaster of emotion as you realize you may win - no you won't - oh but you did get a small price.
It's only stupid if you see it as an investment. See it as entertainment and it's no more dumb than paying to watch a movie.
I saw a 'gator right at the edge of the VAB parking lot last month. In a drainage ditch, up to the fence, cars parked right on the other side.
With luck, they'll start incorporating our radio transceivers. I hear that SpaceX flies with several USRPs now, so that's not completely unrealistic. That might be as close as I can get. Anyone who can get me a base invitation, though, would be greatly appreciated and I'd be happy to do some entertaining speeches while there. I need a base invite for Vandenberg, too. I got in to the official viewing site for the first try of the last launch (and that scrubbed too), but this next one is on Pad 6.
I was in Florida to speak at Orlando Hamcation and went to see the DISCOVR launch at Kennedy Space Center. I paid $50 to be at LC-39 for the launch, an observation tower made from a disused gantry on the Nasa Causeway between the pads and the Vehicle Assembly Building. A crawler was parked next door! A hot sandwich buffet, chips, and sodas were served. It was cold and windy! I watched for a few hours and unfortunately the launch scrubbed due to high stratospheric winds.
The next day, Delaware North Corporation, which operates tourism at KSC, decided not to open LC-39 or the Saturn 5 center for the launch. This was the third launch attempt and I guess they decided most people had left. I was annoyed.
The closest beach was going to be closed in the evening, it's a sensitive ecological area. I ended up seeing the launch from Jetty Park. This turned out not to be such a great location, the tower wasn't visible at all and the first 10 seconds of the rocket in flight were obscured before we saw it over a hill.
What's a better viewing location?
It is ridiculous of course. It is also a common attitude among PI's toward their postdocs and students, especially in high-profile, high-pressure labs.
This letter from a PI to a worker made the rounds a few years ago. The PI claimed later it was a joke. It doesn't read like a joke, and the exact same attidude is not uncommon at all:
Test equipment is allowed to transmit and receive on those frequencies. If it looks like a radio, it can't. I have a number of cellular testers hanging around here that can act like base stations, mostly because I buy them used as spectrum analyzers and never use the (obsolete) cellular facilities. Government has different rules regarding what it can and can't do in the name of law enforcement, although FCC has been very reluctant to allow them to use cellular jammers.
If you can afford it, something from Ettus would better suit your application.
We think after we build this new PCB we can go for the croudfunded manufacturing run. It's mostly surface-mount, and we expect to sell assembled boards in this run, and then the next version will be fully-packaged radios.
Happiness is twin floppies.
