I found myself looking for vimtutor-like text-based tutorials, and threw this together to make them easy to make, with or without the benefit of source material. I don’t think the prompt instructions are totally final yet - feel free to reach out if you run into issues or have suggestions.

There is a whole hierarchy of right of way on the water, but a better rule of thumb is that the less maneuverable boat generally has priority.

I agree with you, the earlier post says people only do things out of self-interest, and I was surprised that nobody else had disagreed or mentioned it’s an unfortunate way to see the world.

You don’t think people ever do the right thing just because it’s the right thing?

One nice thing about designers is their tie-breaking ability for non-designers. Design, being something we all think we’re right about, is easy to lose lots of time going back and forth on with non-specialists, while it’s much faster to send to a pro.

But I generally agree with you, I think the world would be better if everyone was more thoughtful about this sort of thing.

This seems like short-run thinking winning. I don’t want to have to think about if companies I interact with are going to slowly diminish the product. This sort of thing undermines that - it’s a rare good thing for companies to be trustable, and a bummer when it doesn’t hold.

There are all sorts of games brands/retailers play with these. It also wouldn’t surprise me at all if Walmart avoided language that went as far as collusion, but did make clear they needed a certain margin and were willing to pay a higher price.

It’s pretty common for there to be a ‘minimum advertised price’ (MAP) where a brand can cut retailers off if they advertise a price below it - this is why so many stores will have the exact same price on a given product and why you’ll sometimes see the ‘lower price in cart’ message.

It sounds like the issue here is that Walmart managed to get Energizer to have a higher MAP price, but I’m not sure how much more collusion-y that is than MAP prices in general.

I’m not an expert, but it was about the size + hairiness that I associate with bees.

A question for any bee experts: there have been a few times I’ve been eating a sandwich or sushi in a nearby park in NY, and a bee has flown over, found the meat in whatever I’m eating, spent some time cutting a piece off, and flown off with it. Would anyone know what sort of bee this could have been, or any other info on what was going on?

New comment by cdbyr in "Airbnb removed my negative review"

cdbyr — Mon, 02 Jan 2023 16:41:29 +0000

There was a line from Jeff Bezos, ""One of the early examples of this is customer reviews. Someone wrote to me and said, 'You don't understand your business. You make money when you sell things. Why do you allow these negative customer reviews?' "And when I read that letter, I thought, we don't make money when we sell things. We make money when we help customers make purchase decisions."

The incentives are different at different levels of the business. There could be someone with a shorter-term outlook making these decisions, or (more likely imo) it was a very quick misapplication of the policy based on skimming the review. Acting as a first reviewer actually seems like a great application of LLMs, where attention won't flag + they can hopefully be tuned to only focus on the policy-relevant pieces.

New comment by cdbyr in "Podcast on (Massive) Ad-Fraud"

cdbyr — Tue, 04 Oct 2022 03:40:20 +0000

It's an interesting question.

If the fraud were evenly spread out, and if all advertisers had the same goal, the equilibrium bid just adjusts for less valuable clicks/interaction/etc (in line with what the earlier commenter mentioned), and the advertisers pay the same amount as in a world without fraud. Fraud isn't evenly spread out though, and advertisers are sometimes unaware, so it probably does hurt them.

The other loss is from honest publishers (think newspaper websites, etc.) - they're having to split payments with fraudsters, even though they're providing all the value to the advertiser. Downstream effects mean the publisher is probably producing less, showing more ads, or using other ways to replace ad income.

I hope not - for projects with any complexity, knowing I’ve got a checkpoint means I don’t need to think hard about doing risky things. I wonder if Microsoft keeps stats on how many Office users use auto save.

Agreed with your comments on muscle memory and very cool project overall.

An issue keeping me from wanting to use this: holding down the directional keys doesn't move the cursor multiple times - it's one keypress per movement. In the desktop environment, one can hold 'j' to go down, and since there is so much vertical movement, it's important that that's replicated.

Glad it was interesting! I’d realized the part referenced was a while in, so wasn’t sure if anyone would want to read that far to get to it.

I think this is overall very accurate and owning one’s own onboarding is a productive framing. For the content of the introductory meetings, beyond a beginner’s mindset, I’ve found the idea of ‘generating pull’ useful. If you’re looking for specific places where mutual wins can happen (and have some flexibility on what you’re working on), your new colleagues will be a lot more invested in working together, and you’ll probably get up at speed a lot faster.
