Single use disposable toothbrushes (such as Wisp).

I'm a bit confused by the pricing. It's listed at $15.99, but lower down the FAQ gives the price as $4.99. I've seen six-packs of toothbrushes at a dollar store, so I don't see what Wisp's selling point is. Individualized packaging?

The 24-pack version of the Wisp is $0.21/brush. It looks like a better choice would be this 144-pack at $0.07/brush. This Wisp doesn't require toothpaste, which is nice if you're going to carry it with you, but if you're giving a toothbrush to a guest they can just use your toothpaste.

Are there cultural differences between Europe and the US? Where I live, it's usually the guests who bring their own contact solution/toothbrushs/pads/tampons if needed; the idea of asking a host for a spare toothbrush (I don't need the other things because I neither wear contact lenses nor am female) wouldn't even occur to me.

In the US the guest is still expected to bring them, but as a host it's really nice to be able to provide for your guest if they need it.

Flashlights (that you can find in the dark)

Being able to find your flashlight in the dark used to be good advice, but if you carry a cell phone you can use that to find your flashlight.

Point of order - Your comment is not a point of order. A point of order is an interjection about process in parliamentary process. Your comment was a clarification about terminology, which does not have the precedence of a point of order.

[This is meant to be silly, not harsh; but if you want to make fussy terminological points on LW, I will do likewise...]

Isn't your comment then also not a point of order?

"Movement building" can mean a ton of things. I would actually like to taboo it since it's so broad. We should evaluate individual ideas on what they actually achieve.

Things that EA folks have done which seem like they might be "movement building" --

  • giving TED talks
  • running the EA camp at Burning Man
  • putting on the EA Summit
  • founding GiveWell
  • posting on the EA Facebook page
  • pledging to give 10% of income

you see, these things are all quite different...

A few more examples of movement building:

  • Hosting/attending meetups
  • Writing blogposts
  • Getting media coverage
  • Coining terms
  • Introducing people to each other
  • Drawing Jack Chick-style pamphlets and handing them out on street corners

Also, as Ben notes,

Given these considerations, it’s quite surprising that effective altruists are donating to global health causes now. Even for those looking to use their donations to set an example, a donor-advised fund would have many of the benefits and none of the downsides.

Still not so sure. Legibility and inferential distance are major constraints here. When trying to explain earning to give it's much easier if the "give" part is something obviously good. Donor-advised funds combined with an intention to choose effective charities aren't "obviously good" in the same way as a donation to a charity.

A relatively tame one: make a huge number of tiny donations to effective charities. Donations small enough that they cost more to process than they're worth:

The most extreme case I've seen, from my days working at a nonprofit, was an elderly man who sent $3 checks to 75 charities. Since it costs more than that to process a donation, this poor guy was spending $225 to take money from his favorite organizations. -- GivingGladly

I associate genders with digits, not numbers - so 15 is 1 and 5, 26 is 2 and 6, and so on. 3 is female.

Neat; thanks!

I associate genders with digits, based on their shapes. 1, 4, 5, and 7 are distinctly male. 0, 2, 6, 8, and 9 are distinctly female.

3? 15? 26? 52? -1?

But note that most real world sounds are a combination of many frequencies, so training on sine waves may not be what you want.

I would think that training on them provides useful skills that generalize more broadly. It's probably not perfect but it's easy to create cards with binary choices that can get progressively more difficult.

The goal is getting to a point where I engage into deliberate practice of distinguishing sounds and using Spaced Repetition to do it.

If anyone who's good at sounds has better ideas about creating a Anki deck to train distinguishing sounds, I would be happy to hear ideas.

I also try to train phonemes, but creating good cards for it proved to be hard. The first cards I created where simply to hard for myself as I'm not good at audio perception.

I can hear a lot more in a Salsa song than I could hear 5 years ago. I think that it's worthwhile to invest significant time in getting to perceive more bits of reality in daily life. I'm still at the phase of experimenting about how to train myself and others to have richer qualia, but I think it's an area worthy of further investigation.

Pitch seems to me like a very straightforward concept, but I'm also willing to learn other ways of distinguishing sounds.

I also try to train phonemes, but creating good cards for it proved to be hard.

Instead of phonemes in isolation, it should work to train on them in words as minimal pairs. For example, to train the difference between /b/ and /d/ you would test discrimination between /bog/ and /dog/, /cab/ and /cad/, /cabby/ and /caddy/, etc.
