Bad names make you open the box

The other thing about filterPromotedPosts is that it kind of sounds like the input is promoted posts and the output is some unspecified subset of them. filterPostsForPromoted avoids that but starts to feel unwieldy to me. (But maybe I should just be more okay with unwieldy names.)

Even in an impure language I think filter sounds to me like it would return a new list rather than editing in place. That's how the python filter function works for example, and Perl's grep (which is basically a synonym for me), and I had to look this up but JavaScript's filter too.

2adamzerner6dI have the exact same feelings here. It's funny how hard this is to name! Although these issues go away if you think about the name as only one part [https://www.lesswrong.com/posts/NYaLudjSqsYtZDB2t/bad-names-make-you-open-the-box?commentId=7b5v84388NZm8DeW9] of the boxes label, and the signature + docstring as the others. Sorta. I think it'd still be nice if the name did as much of the job as possible by itself without having to consult the signature or docstring. In my experience the ideas of functional programming are things that a lot of people just aren't aware of at all. I know that for me it was about seven years into my journey as a programmer before I started learning about them. Thinking about the people I have and do work with, I could very well see them using filterPromotedPosts to mutate a list of posts. So in that environment, it seems like it'd be nice to make it extra clear that "this function isn't actually mutating anything". (Then again, I could also see them mutating stuff in getPromotedPosts too.) But in a different environment where the convention of "filter" being pure is strong enough, I agree with you. And I think that it'd often make sense to aspire towards this sort of environment. It's interesting how much the right name depends on this sort of context.
We need a standard set of community advice for how to financially prepare for AGI

Search-in-Territory vs Search-in-Map

I'm not sure if these are examples of the thing you're talking about or something else, but:

Consider a missile that's guided by GPS until it reaches its rough target location, then uses sensors to locate the target precisely. (Though arguably this is simply "SIM followed by SIT".)

Or consider when I do something similar myself. I use the map on my phone screen to guide me to roughly where I want to be, and then I use my eyes to guide me to exactly where I want to be. And I don't just switch from SIM to SIT; I keep checking with both, in case e.g. I miss it and go too far.

4AllAmericanBreakfast9dThose are nice examples/test cases! Here's what I think is the right way to understand what's going on in the phone case. Let's say you're looking for an ice cream stand in a park. Your brain takes input from the phone and your eyeballs. It synthesizes them, along with memories and other sense data, into a prediction about where you should walk and what you should look at in order to find the ice cream stand. Based on that mental synthesis, it sends outputs to your body, causing you to walk/read/look around. In this conception, there's ultimately only "search in map," where the map is in your brain. "Search in territory" is just a fancy label we give to a certain subset of sense impressions that aren't focusing on what we conventionally call a "map." I think that John is interested here in this distinction from a more practical, engineering perspective. When is it efficient for some instrumental goal to create or consult what we'd conventionally call a "map?" Here, the important thing seems to be the distinction between accumulating and storing information in a legible format, versus acquiring data anew each time. I'm just pointing out that ultimately, there has to be some abstract synthesis of signals. The idea of transducing signals from one form into another might be more helpful for understanding this side of things. Here, the important thing is tracing the transduction of information from one processing mechanism to another. To me, these seem importantly different, so I'm advocating that they be split apart rather than lumped together.
Search-in-Territory vs Search-in-Map

We're want the rock that's closest but not higher, and that's what we get. We don't necessarily get the closest rock, but we do get the best one, which is what John said.

An Intuitive Guide to Garrabrant Induction

The logical induction criterion requires that, in the limit, all logical inductors assign probability 0 to Fermat’s last theorem being false. Conditioning on an event with probability 0 is ill-defined, so we have no formal guarantee that these conditional probabilities are well-behaved.

From what I understand, an LI need not assign probability 0 to Fermat's last theorem at any finite time. She might give it price on day . In practice I don't know if the LI constructed according to the paper will ever assign price to it. For all I know that would d... (read more)

Anatomy, diseases and aging damage

I took a screenshot from my anatomy atlas app, hopefully it's a bit helpful. https://i.ibb.co/RpMfpJX/Screenshot-20210603-191621.png

The muscle Christian is talking about is highlighted in blue, and the tendon sheath is the blue tube at the bottom. My read is that that sheath had moved to the side a bit, closer to the others?

4ChristianKl16dAnatomy atlases like that often include the tendon of the muscle in the marked muscle, so I'm talking roughly about the end of the thing that's marked in blue on the image. From the view of that image, the blue muscle is the thing that's most left at that point. In my case, it was moved right from that and so that you would still see it when looking at the hand from that perspective instead it being hidden on the other side of the hand.

For Better Commenting, Take an Oath of Reply.

So, this seems like a fine policy. But calling it an "oath of reply" feels like it waters down the word "oath" in a way I dislike. (cf. the people who've taken the GWWC pledge, and said that if in future they think it's not a good idea, they'll just stop doing it.) Especially when the stuff you've said should be a universal understanding (around self care, rudeness, circumstances changing) is left implicit. That stuff won't be universally understood.

2AllAmericanBreakfast16dThat's a good point. I picked the word "oath" intuitively, and I can try to articulate why. First, "policy" feels more detached and state-ish than I wanted. I wanted a word that conveyed some emotional depth and a spark of human connection. Also, "policy" has the implication of being explicit in its details, like a law. By contrast, an oath is about building credibility without being specific about what actions to take. Here's a sample from the Hippocratic Oath: * "I swear to fulfill, to the best of my ability and judgment, this covenant: I will respect the hard-won scientific gains of those physicians in whose steps I walk, and gladly share such knowledge as is mine with those who are to follow." Policies can also have statements like that occasionally, but they are also often extremely detailed and voluminous: * "Employees accrue 2.15 hours of emergency personal time per pay period. On an annual basis, this is the equivalent of 56 hours. Employees may use emergency personal time up to 56 hours." But if you want to call yours a policy, more power to you!

Finite Factored Sets

Imagine that I had a bit, and it’s either a 0 or a 1, and it’s either blue or green. And these two facts are primitive and independently generated. And I also have this other concept that’s like, “Is it grue or bleen?”, which is the XOR of blue/​green and 0⁄1.

There’s a sense in which we’re inferring X is before Y, and in that case, we can infer that blueness is before grueness. And that’s pointing at the fact that blueness is more primitive, and grueness is a derived property.

How to compute the probability you are flipping a trick coin

So I was thinking of this paper (pdf), which I misremembered somewhat - you can't make a coin biased for "toss and catch", but you can make it biased for "toss and let it bounce". (And for "spin on a table".) Given that, "can't bias a coin" is probably too strong, though it's in the title of the paper.

Props for suggesting an actual experiment! I didn't feel like doing it though :p

How to compute the probability you are flipping a trick coin

I've read that it's not possible to bias a coin - you can bias a coin toss if you know which way up it starts, but the coin itself will always be fair. But I confess that I don't know what assumptions they were making, so for all I know you could make something that would be recognizably a coin but that analysis wouldn't apply.

Can Bitcoin transition from PoW to PoS?

As long as the price of bitcoin is higher than the expense of mining it then PoW is not a waste in economic terms.

But only if the expense of mining it is considered to include externalities. If you include those, then this is perhaps true, but it means we can't reject the premise "PoW is a massive waste of resources" offhand. To reject that we'd need to further establish that the miners' surplus is larger than the externalities. And I note that if the miners' surplus is large, more miners can join, though there are complications in this argument.
