The long term stability is much better than a typical GPSDO, for sure. I was just making a somewhat pedantic statement of what’s in the atomic clock box.

(also a time-nuts lurker, who’d occasionally worked on related things) The actual atomic frequency you’re locking to in an atomic standard is an obnoxious frequency in the GHz Range. For example Cs is 9,192,631,770 Hz. To get a 10 MHz reference frequency out of that requires a very high quality quartz oscillator and a PLL loop, so there’s a PLL right off the bat.

PSA is not fool proof test, and is susceptible to false positives. A substantial fraction of men, in the 40+% range have prostate cancer at death. The treatments for it can be painful and have long recoveries, so there's not obvious solutions.

Believe me, we noticed that clearly at the time.

More SMS spam about my overdue toll?

Ploughing a field is a very different activity than moving material from one place to another.

How many people with polio do you know? What’s her explanation of why polio almost disappeared after everyone was vaccinated? Couching a bunch of BS in “if she’s right” makes you sound like a shill.

Wow. Talk about zero situational awareness.

Ah, an economist from George Mason. Say no more. I expect he has no children due to the negative economic impact of child rearing.

That's an urban legend. https://www.scientificamerican.com/article/fact-or-fiction-n...

How is the typical person supposed to decide the best path of care? How do you incentivize competition while keeping standards of care up so that people receive good care with highly complex tradeoffs.

Oh sure, but the Catholic Church didn't have to answer to a bunch of analysts whose only skill is fast excel spreadsheeting.

I believe the GNURadio folks have implemented at least some of this, so it might be worth poking around GNURadio for a bit, Tags are what you're looking for.

Not if there's only 5 documents.

But will the computer add appropriate tagging and links?

Perhaps it's because there's little skill overlap between hardware engineers and software engineers? Perhaps it's because they have different career goals and desires?

I'm going to go out on a limb and claim that human sacrifice is bad.

You're assuming that parents who are homeschooling intend to provide their children with a good education. However, what about people who claim to "homeschool" their children but don't actually follow through, leading to uneducated adults who can't support themselves. I think that assuming good intentions for everyone is a problematic assumption, and you need to manage policies for bad actors as well.

Why is that a problem?

I'm pretty sure this wasn't an accident

Without comments like that, HN would have 1/3 of the total comment volume. I find it highly entertaining.

You've never developed any hardware have you? Patents aren't the problem.

Looking at the number of failed kickstarters for physical objects that are multiple orders of magnitude less complicated than a nuclear power plant with new technology might be instructive.

It's inherently a broadband device, with no output filtering. No surprise that the output is full of harmonics. I built several application specific RF front ends for Ettus SDR's at a previous job, it's mandatory for any kind of professional use.

One of many Govt focused RF companies. Start from Watkins Johnson and look at the spinoffs, although they've mostly absorbed into Bigger defense contractors at this point Boeing bought DRT in '07?

WiFi is hard to support, it's very complex from a signal processing and timing perspective.

Well, it would also cost at least 10x what a dual purpose LoRA/WiFi radio would cost if it were built out of LoRa parts from Semtech and an ESP-32.

It's not a tools problem, it's a people problem. Use whatever tools your team is used to, and build culture on top of that.

For the most part, transmitting radio in the US is only allowed in a few frequency bands, referred to as the ISM band. These have pretty strict transmit power and duty cycle limits. If you get a ham radio license, then many more bands open up to you.

Lolz. Low power in the wrong place can be a problem.
