The first example has a miscalculation; if you invest 1k and the EV is 900, then your choice has negative ROI, not positive.

He's calculating EV above cost. If you look at the calculation, the first term is -1000 to account for the initial investment. So the final value is tell you that you got back the initial money plus 900 more.

I love docs written like this, and writing culture generally. But I've also seen something like this backfire a bit.

I think this approach is particularly good for docs where the assumption is the audience wants to understand why you reached the conclusions you came to, and the doc is sort of a persuasive argument. I think this is a valuable doc (and how I like writing and reading), but it is not always the case.

I think often you do want to start with the conclusion, the "end" so to speak, to orient the reader. And also to address the reader who trusts your judgement, and just wants to get up to speed. I've seen a lot of cases where the audience might not be ready/want to follow along w/ a train of reasoning, they want to know the punchline. And once they do, then they might want to follow up.

Nothing wrong with sticking a summary up top, and then laying out the arguments below.

One process that can work:

Step 1. Brain dump into a doc (consider using dictation to get more thoughts down faster)

Step 2. Have an LLM give it structure & progression. You are ordering your thoughts for readability, so you'll probably want to throw it away. You're still refining your thoughts at this stage.

Step 3. Take the LLM output as a starting point, or write an outline from scratch. Flesh it out into a first draft

Step 4. simplify: cut words, swap big words for small words, etc.

Step 5. Repeat step 4.

LLMs bridge the gap from word-vomit to structure. You should be willing to throw away what you get from the LLM.

At least 30% can always be cut. It's amazing how much can be trimmed without losing the intent.

I feel like the process of editing my own stuff is at least as important as getting it down. That's when I go back through it and realize all the conclusions I leapt to, things I didn't thoroughly consider, and other flaws. I think people really undervalue writing as a focus tool. But maybe that's just me, YMMV.

I think the same thing about a lot of code, too. Sometimes you really are just hammering out boilerplate. But a lot of times even writing test code is a great opportunity to realize the main code could be improved. But the LLM probably won't tell you that.

That's the point. They had sustainable and clean technology. It was a sweet spot.

They also mined by tearing apart mountains, and threw noticeable amounts of lead into the air doing it.

> Roman-era mining activities increased atmospheric lead concentrations by at least a factor of 10, polluting air over Europe more heavily and for longer than previously thought, according to a new analysis of ice cores taken from glaciers on France's Mont Blanc.

A lot less than modern technology manages, but a lot more than nothing. And that with a much smaller population.

> The site was an immaculate knock off ...

Then I can picture a great way, locally, to screw these knock off big times.

Either the site is a great knock off, visually similar (if not identical) or it won't fool people, right?

So what about this: what about the browser saving, locally, screenshots of the login pages you visit.

Then, when a new login is made, compare, visually, the page to what's saved and see if any saved pages are similar?

"Oops, the page www.banklng.com looks nearly identical to www.banking.com which you visited previously, they're probably trying to scam you!".

I feel like PassKeys and browser-integrated password managers both solve this problem better already. And yeah they're extra things to do, but so is this.

I keep wondering how we'll get rid of used batteries and panels in the future.
breischl · 2 years ago
There are recycling pilot projects out there, but yeah it's a problem.

Do you also wonder how we'll get rid of used coal power plants, massive piles of toxic fly ash, and tons of pollutants from natural gas plants? Because so far the answer is not good.

I wouldn't say the planet "barely" supported life before the oxygenation event. Otherwise we wouldn't have as much fossil evidence as we have.

I'd rephrase what you wrote with our current technical limitations make it more feasible to detect life by finding something that would make astrobiologists say woah, how can that possibly happen?

I believe you're talking about Earth, and the person you're responding to was talking about Mars. At least I don't think Mars had an oxygenation event or fossils?

I feel like a similar thing happens in "real life" sometimes, not just on websites. Back in high school, I used to volunteer at an animal shelter, and we had an area out back where we'd walk the dogs or let them run around in one of a few fenced in areas throughout the day so they could go to the bathroom and get some exercise. The door leading out here was located in one of the rooms with dog kennels, so people coming to potentially adopt a dog would walk through this room a lot, and often they'd try to walk out back and watch or participate with the volunteers and staff taking some of the dogs out. We'd ask them politely to go back inside because they aren't allowed out there and point out the very large sign in large font on the door saying this, and every time they'd always act very surprised because they claimed not to have seen it. I'm sure some people were just feigning ignorance because it seemed easier, but the sheer number of people claiming it makes it believable that at least _some_ of them genuinely didn't notice; they saw a door, they wanted to go through, and they opened it without processing the words right in front of their face.

Definitely a thing. Just yesterday I was annoyed by my auto mechanic's credit card fee, and said they should've told me up front.

She pointed out it was on a sign on the counter that I was looking at that moment, and had also been there when I dropped the car off the day before.

I'll have to check out that tool.

Generalized social media is looking more and more like a mistake. There were previously forums, and they were centered around a topic. Then Reddit and Facebook came around and killed those by making it easy to create and find those communities. Now they're coming back. I want a local equivalent to Reddit, without the rest of Reddit. Beyond that, I don't need more social media that has no link to my IRL activities.

Also, the comparison to MySpace isn't fair. Tom was far cooler than spez ever will be.

<lereddit>We did it, HN! This is exactly what I'm looking for. Take my updoot, kind stranger!</lereddit>

Isn't the local equivalent of Reddit just NextDoor? Which seems to mostly be worse, from what I can tell.
breischl commented on Bluesky's stackable approach to moderation   bsky.social/about/blog/03... · Posted by u/steveklabnik
efitz · 2 years ago
I’ll be honest. I really liked the BlueSky idea and was an early adopter. But I deleted the app last week when you announced your Trust & Safety team, or at least hired a new leader for it.

In my mind (and many other people), “Trust and Safety” is a synonym for censorship.

We live in a time where censorship is becoming a huge risk to freedom. A free society needs to be able to debate, and anyone or anything that decides that it has the wisdom to set limits about what people can discuss, is a threat to freedom.

I had hope that BlueSky was choosing a different path but now I guess not.

If I understood the article correctly, you can get a feed that isn't moderated by their team. So I'm not sure what your complaint is? That other people can get moderation if they choose to?
