This is an interesting way to think about how to get to a minimal form of a complex system. A friend in college told me of a research project that had managed to balance a simulate…

No, the bicycle is unstable. PID doesn't work well there. In addition, it is controlling a coupled 3D system (which is unstable). This is much more than 3 PID controllers.

This sounds like the feed of a single male. Facebook showing sleazy content/ads to single guys predates AI by a lot. Try removing your single relationship status from your profile …

Legged robots can be more efficient, in theory. Whenever you drive/walk in soft terrain, the wheel/leg is constantly climbing the ramp created by it sinking into the terrain. In a …

> the ordered dosage of methylene blue was 1mg/kg/hr That's 5X what is considered a safe dose. Up to 2mg/kg/day is considered safe. Double that with care. But they were dosing ever…

Watch out of patent problems. There was a major dust up between Sonos and Google over audio sync technology. Disclaimer: I've worked for both companies, but not on that

Very cool write up! I'm amazed that it's running on AAA batteries. The introduction to SDR (software defined radio) is much appreciated. Edit: defined, not designed

This talks about the "what" of the code, but you have to also convey the "why". If you have a well understood problem space and a team that is up to speed on it, then the "why" is …

That depends on if it's in the grass that the cows eat. They first researched iodine in cows because there isn't much iodine in the grass around the great lakes. This area was know…

Talon Speech recognition also includes mouseless options and eye tracking: https://talon.wiki/Quickstart/Hardware/tobii_5 Works on Mac, Windows, and Linux

I keep wondering how this compares to Zig and WASM? Zig has a nicer syntax with fewer foot guns than C. It can also compile or link with C.

Autel Nano or Lite+. Some Autel drone are made in the USA, but not all. Edit: added the Lite and fixed formatting

D3 is really a hormone. You are showing the classic symptoms of it becoming too high. If/when this happens, discontinue supplementing for a few days and then you can resume at a lo…

You need to treat D3 as a hormone with an ideal range. When your blood levels gets too high (typically over 100) you have trouble sleeping and might have restless leg syndrome. Whe…

The National Science Foundation (NSF) runs the research activities on the base. They don't allow anyone random there and they would be immediately obvious. There are some Antarctic…

Yes, it's NZ time. Since most of their flights and logistics are through NZ it makes the most sense to use that time zone. The sun just orbits and never sets. So any normal day/nig…

I wondered if the C-17 would be a game changer for them. It was just entering service back in 92. They had the land landing strip back then, but it's too short for a C-5. The C-17 …

It's amazing that they have the bandwidth for this. I assume there is a US or NZ based server that serves the world, but still. I was there in the 92-93 season. We were lucky to ha…

The bottom end of the housing market is usually junk or otherwise tied up legally. Just because you get hits, doesn't mean that's a viable option. I just did a housing search recen…

Let me attempt to explain what I think he meant. Some families are dysfunctional. Addictions can be big here, but the personalities of the parents can drive this without any alcoho…

I would recommend "why we get fat" by Gary Taubes. Calorie counting has be disproved so many times, but it sticks around despite the science being against it. If you're a doctor or…

They have done studies that showed that it "helped" about 60% of the time (sorry I don't have the reference). "Helped" is a far weaker term than cured. I've read some of McCarthy's…

A reference would be helpful :-) Gluten and dairy are in almost all packaged foods. They drive cravability in a big way. So I'm guessing any "debunking" was funded by someone makin…

Autism is a wide spectrum. Some would consider ADHD part if it. If nothing else, there is lots of overlap.
