I’m not quite getting it. Would you be willing to explain it using a toy example?

I believe people have found ways to reduce drag with lasers and microwaves so you might be on to something.

It could be a new type of scram jet, right? A normal jet engine has to slow down supersonic air to subsonic to combust it which is inefficient.

We should consider using this on Venus or mercury.

I’m a huge climate person. I come from ancestors that laid down the early climate change work. But This methodology seems kind whacky. I think this kind of thing hurts our credibility in the long run.

I remember an interview with a startup where I couldn’t figure out what their product was and they got more and more annoyed with my questions.

I ended up with something with the cloud.

Besides that you actually want your unit to struggle a little in order to have enough run time to control humidity.

It’s actually a problem if you have an overpowered system.

I found tower fans are a game changer. They are fairly quiet and move a lot of air.

I prefer them to ceiling fans plus no installation and you can keep them when you move.

> "Extract this to a separate function please"

This sounds really bad. Even if you’re their boss. You’re dealing with professionals and part of that is considering their input.

I’d start with the assumption that they know what they’re doing and might have had a good reason and phrase it from there. Even if not true it sets the right tone of respect.

Why not just use multi processing?

GOOD Point by my wife! Why can’t we have a blower on a belt to accomplish most of the sorting? Plastics blow one way and glass stays on the belt. Throw in a magnet and make eddy currents to trap metals.

mrfusion — Sat, 25 Jun 2022 22:20:08 +0000

How about any company that’s worried about it’s code being copied submits a copy for copilot to check against. If copilot generates any of that code it just doesn’t output it.

I’ve never used it but I imagine it would help a lot with the programmers equivalency of writers block.

mrfusion — Tue, 21 Jun 2022 15:41:35 +0000

How smart is SQLite at detecting column types from Csv data?

I once wrote a Python script to load csv files into SQLite. It had a whole hierarchy of rules to determine the data type of each column.

You’d think there would be a plausible hormesis explanation for the benefits of moderate alcohol intake.

Lots of systems in the body work this way. Eg we grow our muscles by literally damaging them and having them grow back stronger.

FYI it’s actually all news. It’s just that you know some science and recognize it more there.

New comment by mrfusion in "Ask HN: Have you had success with improving your reading speed?"

mrfusion — Sun, 19 Jun 2022 13:42:00 +0000

IMO it’s not a good idea. I feel like I hurt my reading comprehension and enjoyment by learning speed reading techniques.

Now the temptation is always there to speed up on a few paragraphs and it’s hard not to.

But that 10kw isn’t going directly into your house. The attic is designed to vent the air and let that hot air escape.
