Stock price changes should be reported on a logarithmic scale, something like a decibel, perhaps finer, a centibel, cB. You go down 90%, that’s 10x less, -100 cB. You go up 900%, that’s 10x more, +100 cB. A 5% decrease is 1.0526x less, -2.2

> This argument seems like it could be used to absolve anyone of guilt for using racist terms. "I'm not racist, that person chose to be offended by my statement". Technically, yes. But what matters (should matter) in the

Yeah, that’s probably the biggest weakness of this analogy—it’s kind of useless.

Don’t know if it is. But in computer science state machines are usually finite or at least discrete. Time evolution in quantum mechanics is certainly continuous, not discrete. Discrete are only some observables.

If you refer to measuring and wave function collapse in QM, then yes, but for that you need interaction with the environment (the observer), that’s why I specified “isolated”. Regardless, even the wave function collapse is a state transitio

Not in the standard regime of finite state machines. If you allow for infinite continuous state machines and infinitesimal steps, then it’s no problem. Every classical mechanical system is fully specified by positions and velocities. Transi

They serve a different purpose. Pyenv enables you to maintain several Python versions. You can that use the venv module of each respective Python to create a virtual environment with a Python at a given version.

Many journals I'm familiar with allow you to suggest referees, as well as suggest which researchers should be avoided as referees. If I'm publishing something that is competing in some sense with the work of other people, I will u

I'm using the Kitty terminal, and observed the script launch delay described in the blog post. After adding Kitty to "Developer Tools", the delay disappeared. Thanks!

Ok, so things haven't really changed that much. They don't actively prevent you from getting the data, but they don't make it easy either.

You can easily export all the raw data (fit/gpx files) directly from the Strava website, without giving access to any 3rd party.

by jhrmnn 6y ago
At least Strava is reasonable about getting your own data out of it. Not sure if this applies just to EU users, but it's easy to download a full archive with the original uploaded gpx/fit files (whether they came from a manual upl

I think you need to discretize time very finely to have believable collisiom physics. So it’s orders of magnitude more than 10x.

Your first point is very apt! Never thought about it like that, but it makes perfect sense.

Agreed. I find that the original cause in most activities producing procrastination is lack of purpose. So in my case the ultimate solution to procrastination is to do only things that I find purposeful (both on short-term and long-term sca

It's pretty hard to keep the design open once the whole architecture is bigger than what a single programmer can keep track of. Say, the Linux kernel. The overall architecture is fixed, there's no way around it. At that point, spl

This is one school of education. The other is the Finnish model, with no separation. I am yet to see some comprehensive multinational study that would suggest which is better. (Better for the students, or society as a whole?) It’s probably

Your last paragraph makes a valid point. The question then is whether when the schools became “softer”, they replaced the math and sciences curiculums with something else (politics, economy, governance) or whether the kids themselves starte

I have above-average hands and I do operate iPhone 7 one-handed. But reaching top left corner with my thumb is a bit of finger gymnastics.

If they did PCR tests, and didn’t consider that N days (I don’t know the number) after infection you don’t have virus RNA anymore, they’re stupid. Really stupid. If they did think of it and now the guy claims this proves there was no virus

I don’t know. I can only assume they took this into account. I don’t want to be condescending, but do you really think that you just thought of a rather trivial catch that a bunch of expert virologists didn’t think of?

In Germany, the lead virologist in Berlin said that in the beginning they went after cases like yours, testing people who had weird symptoms in February, or even late January, because the hypothesis that the virus had been circulating in Eu

Second this. Vol 1 was the most influential physics book at high school for me. Though be prepared to go through it repeatedly. At least as a teenager with still developing abstract thinking, I had to think things through over and over agai

I disagree. Perhaps in some areas, like electromagnetism or optics, but there are large fields in physics where it's not necessary (statistical mechanics, quantum mechanics, gravity, high-energy physics)
237.
by jhrmnn 7y ago
(not parent) Agreed. But I would also say that physics can actually help you a lot with understanding math. I learned both physics and math very organically at high school, going way ahead the curriculum, and to me it was more like a single

I was a happy user of Terminal.app until I got a 4K display, which I run at scaled 2.5K, so effectively rendering 7.5K. With my Macbook Air 2018, this results for example in a FPS of ~13 when scrolling full-screen in Vim with Terminal.app r

Not sure what OP meant, but I wouldn’t say DNA is the machine. The ribosome is. But DNA is certainly much more than just code to build proteins. Or rather, it strongly interacts with its enviroment, so trying to understand its function in i
