Experts also use bad metrics because they are easier to understand or measure. They just have a slightly higher tolerance for complexity and understand the shortcomings better.

Yeah I'm not saying it's entirely unjustified. The DOW is not the economy, and unemployment is not unemployment. But these are still better numbers than just I personally do or don't have a job.

In that environment, it makes some sense to default to simpler metrics you definitely know and understand.

But of course to do so is basically choosing ignorance which is bad gor society if most people do it about important things.

I think this is primarily two things.
1. Most metrics are hard to understand. For instance, most people don't understand derivatives. They don't get that cars can be going fast if nothing is pushing them.

2. They don't trust that the metrics are defined or measured honestly.

Everytime I would say this, it would go, "oh yeah, that's mathematically true", but it would inevitably bring it up again. It really sped up the initial coding, but it did not do great with debugging or algorithmic design.

I had this problem when Claud helped me with a quantum circuit. Claud would keep saying "wait, your quantum state is entangled with these other bits, you need to measure them to make them classical". I had to keep telling it that didn’t matter as long as I didn't interact with them again.

Example, no 'n' and 'm', a single 'n' is both. No q, x, redundant. Past tense always ends un 'ed', plural always ends in 's'.

I think it could be fun if I ever make a longer book because it would be like a foreign language, but English speakers could still read it. Kind of like creole.

The past couple days I have been engineering a gnome language in my freebie, along with an associated, 6 bit awcii-esque encoding.

Basic idea: English with more consistent grammar, phonetics, and easier to pronunciation. Kids have trouble making two distinct noise. One is gone, done.

To be clear, we should try to make things better, and looking at other cultures is a good way to do that. But it shouldn't be to label us as better, or find things to fix in that culture. It should be to fix ours. They can take the spec out of their eye. Let's get our log out first.

Hot take: different cultures have pros and cons. And some cultures could reasonably be argued to be better than others. And to the extent it exists, white culture sucks. It's antimeritocratic, classist, sexist, violent, and not fun. Trying to do whollistic cultural comparisons is very white.

"Must adapt to the culture they live in", that's crazy. Different cultures have plusses and minuses, but most of its arbitrary. We should be okay with people making culture better.

And especially in the context of immigrants, they generally have "better" culture (less crime, more work, etc).

Oh disappointing. I thought it was a book mark that was a smaller book. I wanted to buy that for a certain someone.

Hot take: capital letters are stupid and shouldn't exist. They don't serve a grammatical purpose and double the size of the alphabet. Most sentences would be read the same
way with or without them, and we have many other tools for emphasis.

Yeah, science is cheap. Especially math/theory. It's crazy undervalued because it's hard to understand. In terms of return on investment, the median may be modest, but that tail is LONG. Like, basically everything cool we have long.

To be clear I haven't really looked into her too much as a presidential candidate. But that's the vibe I get from her and that's a good vibe for the moment.

I'd generally say the right has done a good enough job smearing AOC that she couldn’t win...

But she talks like an actual human whose angry, informed, and principled. That might just be all we need right now. I'd like that to be true.

Lead. Heavy, not worth much, poisonous, but a sweet taste to those stupid enough to eat it.

I think this is the first year that I've looked at my income tax and was not sure whether this money will, on average, be used to make the US better or worse. Not the world, just the US.

In the past I may be concerned about inefficiency, other countries, etc. But this government hates everything.

27.02.2026 09:08 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

So, we can’t trust the usps to deliver things because it's legal for carriers to steal our stuff now? Or randomly destroy it if they hate us? Is that a correct read of this?

??? We don’t make gasoline or parking free for poor people, or food, or housing. I don't know why we should make this one thing free that disproportionately is used by wealthier people. There are lots of ways to help the working poor that don’t waste everyone's time.

26.02.2026 17:12 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

No. The poor disproportionately use busses. Congestion hurts them just like it hurts everyone else. The improved speed also has value to everyone.

Like the intuition is right: cars that use more space should cost more. But the exact way to do that isn't so straightforward. A van shouldn't cost way more than a truck hauling a trailer.

26.02.2026 03:01 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

That would be too complicated to do right. You can only fit about 2 cars driving safely down the road in the space of one bus. So if we want to go by road usage, that car should cost as much as half a bus full of seats.

There are other factors to consider as well, like paying the bus driver, etc.

26.02.2026 03:01 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I mean, my bus is rarely on time, especially in the evening. I hear the ones that just go from downtown to downtown are often on time, but the ones that go to the suburbs are spotty.

Hot take: probability should be mandatory in high school, not statistics.

Statistics fluency, even among scientists, is not great. Part of this is that we teach a bunch of complex statistical tools before establishing the basic concepts of probability. We should focus on the fundamentals.

Interesting. I wouldn't have expected that to have an effect at all.

Combo bus bike lanes might be a good idea if there isn’t much bike traffic. Seems reasonable.

The goal is to make commutes better. Reducing cars is just a proxy for that.

25.02.2026 17:06 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

No. This is a tax on driving cars. Why don’t poor people use the bus? If the bus isn't a practical option, then:
1. That's it's own problem.
2. Removing cars is part of the solution.

I'm myself still in the very cunical phase of thinking, dang I basically can't do anything myself. I need to elect people that will fix the game known as the economy.

Even though my income right now is good, a few more layoffs could screw me so fast and I don’t have enough savings.
