The great thing about poison arrows is that they can be much smaller and still be effective. Smaller arrows means you can carry more of them and also your bow will be smaller and lighter.

A small flour mill is not that expensive, I wonder why more places do not grind their own flour?

I can't think of a better gift for a child then an extra standard deviation of height, IQ, strength.

There are some tribes where men and women have completely different languages, I wonder if we will end up that way with emojis.

Lately I have taken steps to re-learn how to be social. I am doing a lot of social dances, like Salsa, Swing, Bachata. I think partner dance is good training for body language. Also good training for presence, as when you really start dancing, you stop thinking; conversely when are thinking too much you will stiffen up and choke. There are a surprising number of PHDs and other very cerebral people in my local dance scene.

One thing I have learned is that being good at dancing and being fun to dance with are orthogonal. You can be technically quite bad and people will still want to dance with you if you have good eye contact, smile, laugh at your mistakes, tell little jokes, complements, etc.

Conversely there are some people that are really technically good but not that much fun to dance with because they grimace and look away and don't match your energy.

Of course the best is when you find a partner that is both fun and technically good, and this is what I ascribe to become.

The downside of dances is that I don't get a lot of practice at talking, I guess this is something you could learn to do at bars but I don't drink and so have not found really good place to practice a lot of talking.

I try to get the guys from my jujitsu gym to come dance, these are big bad dudes who could really mess you up in fight, but they are all scared to dance with the girls. You will be scared your first few times for sure. Personally, I tend to be nervous in direct proportion to the beauty of my partner, which can be a problem because women that dance tend to be above average in that respect.

Most dances have a 1 hour lesson at the beginning and then social dance after. The lesson part is easy, you just follow the instructions and the teacher will have you rotate partners so you get to meet most of the girls. I tell my guy friends, just come for the lesson part and then if you get too nervous you can sneak out early.

A million drones won't last long in a peer conflict. Most of the drone parts come from china. What we really need is to build our own drone supply chain that does not rely on china.

So my health insurance is healthy living, CrossFit, rapamycin etc. When that fails, I have a 9mm pistol I keep in the safe. I do worry about if I am somehow too incapacitated to use the pistol but not enough to die naturally. Infirmity scares me a lot more then death does.

Now everyone wants social norms to be changed so they feel included no matter what crazy ass thing they are into.

Feels lame to me but I am old so what do I know.

Kodak had this issue for sure.

Then you chase your friends around the neighborhood with your personal attack wasp. Good times.

People rarely react well if you tell them "Hey this feature ticket you made is poorly conceived and will cause problems, can we just not do it?" It is easier just to implement whatever it is and deal with the fallout later.

When I built a robot that had to plug/unplug things 1000s of times it had an air-gun to clean out the plugs each cycle.

I am not sure arc-detection would help you that much in case of a bug because by the time it starts arcing the pin has already melted.

Our mental suffering is not because car is on autopilot. Suffering happens because WE ARE ON AUTOPILOT. So I chose to trade the 30x risk of death for a 30x reduction in mental suffering. Rational? God I hope not.

One big advantage would be cameras mounted on the boom and rear view cameras, as many machines have obstructed views.
