karpierz··on A receipt printer cured my procrastination
Here's an analogy that might make it clearer:

Alice is in a wheelchair.

Bob has a broken leg.

Charlie is unfit, but otherwise a healthy adult.

Alice, Bob, and Charlie would all say "I find getting up the hills of San Francisco difficult". But "doesn't everyone find that hard" conflates the causes and severity of the difficulty for the three of them in a way that isn't useful for making their complaints feel heard, or addressing the complaints such that they don't have that issue.

For example:

Alice could get an electric wheelchair.

Bob could take public transit / Ubers up, or get rides from their friends.

Charlie could take up running with friends.

karpierz··on I'd rather read the prompt
Except part of the job involves lifting things in places where forklifts can't fit.
karpierz··on Show HN: Sonauto API – Generative music for developers
> Message me if anyone's still interested in "dumb" AI like that. :-)

Not sure how to reach out, but I'm definitely interested in reading about procedural methods in music synthesis. Any links describing your approach?

karpierz··on Introduction to Stochastic Calculus
Ito calculus - https://en.wikipedia.org/wiki/It%C3%B4_calculus
karpierz··on The Age of Software Artisans
The question on my mind: how do you figure out what the functions do without reverse engineering?

If I were to guess, you're saying that you reverse engineer the API boundary without reverse engineering the implementation. But then figuring out what the API contact is without documentation seems intractable for most API boundaries.

karpierz··on Biggest ever seen black hole jets; blasting plasma well beyond their own galaxy
Light travels in a straight line - black holes don't "pull" light in, they change what a straight line looks like in the space around it.

The event horizon is the distance where all straight lines lead to the black hole.

karpierz··on Guys what is wrong with ACATS
But then I can't spend my money for several weeks - the feature that crypto can't implement is having the reversal window be wider than the lockout window.
karpierz··on AI Determines Sex of Person from Brain Scans
> I should be able to state that two species have a different lifespan based on a difference in mean age of death - without needing to provide any specific biological mechanism in my study.

You need to control for confounders. For example, if I told you:

- Mean lifespan of species 1 is: 3 years - Mean lifespan of species 2 is: 10 years

Does that mean that species 2 has a longer lifespan than species 1?

What happens when you find out that species 1 is domesticated cattle, which has (almost) all of its males slaughtered at age 2?

You could then say "I meant for two species that are in controlled conditions", but now you need to define what conditions you're controlling, which implies what casual mechanisms you're controlling for.

karpierz··on Spotify calls Apple's DMA compliance plan 'extortion''complete and total farce'
I think that you have a specific lens with which you view the world, and you're contorting the world to fit that lens.

What would it take to convince you that people don't do everything to attract a high-status mate?

karpierz··on I am the cheapest bastard in indie games (2019)
> How does someone find his game before really really good games like baldur gates etc.?

They don't. There have been really good AAA games before Jeff started making games. His business model does not revolve around getting people to play his games before they discover better ones. His business model is to make games that can't be compared like that.

karpierz··on The Fight for Fair Wages
> You're paid what you're known to be worth.

You're paid somewhere between the minimum amount you'll accept and the maximum that the company is willing to give you (which in the case of some VC funded companies, may exceed the amount of profit you generate!)

Where you're paid on that spectrum depends on how much leverage you have vs. the company.

I'd recommend starting here: http://minisat.se/
karpierz··on The first week of US v. Google – Defaults are everything and nobody likes Bing
Apple made them the default because they are the best at monetization of large volumes of search queries from iOS devices. If another company was better at it, they'd put in a higher bid and rake in the profits.
karpierz··on Temptations of an open-source Chrome extension developer (2021)
They're saying it's scarier that ad companies can figure out these things without the data because it means that you can't protect yourself by withholding your data.
karpierz··on How the Rich Reap Huge Tax Breaks From Private Nonprofits
You start by saying that wealthy people can pretty freely manipulate the amount of income they show for tax purposes.

The follow-up is that based on the manipulated income data, wealthy people pay disproportionately more taxes?

karpierz··on Why no Roman industrial revolution?
tl;dr: The author starts with the assumption that the Industrial Revolution is inevitable, and uses that to conclude that the Industrial Revolution would've inevitably happened, while dismissing a bunch of other authors who put a lot more thought into their writing.
karpierz··on Smart Contract Security Field Guide
I'm not talking about code.

The goal of the transaction is for the Spanish bank to have access to USD. In the example given, the Spanish bank would then have to take the crypto it got and trust an exchange to give it USD in exchange for the crypto.

How do you get USD to the Spanish bank without trusting a third party?

karpierz··on Smart Contract Security Field Guide
How exactly does the Spanish bank get the USD that the American bank sent without trusting a third party?
karpierz··on Bayesian methods to provide probablistic solution for the Drake equation (2019)
There's the bonus problem of: even if you magically have correct priors, you still need to assume that Drake's Equation is a good model for the generation process of civilizations. If the equation is missing terms or has extra terms, no amount of Bayesian reasoning helps correct for that.

It's like thinking that you can use Bayesian reasoning to determine the likelihood of Russell's Teapot existing.

karpierz··on Bayesian methods to provide probablistic solution for the Drake equation (2019)
> And yet nobody seems to be aware of it, and both the popular and scientific press continue with the “where are they?” Fermi paradox headlines.

A reasonable explanation here is that the paper is not correct because it relies on unfounded priors, which is generally where most Bayesian work falls flat.

karpierz··on Beyond introvert vs. extrovert
To add to this, I'd say that when people say "deep conversation", they generally mean "comfortable conversation".

A lot of conversations that I've heard described as "deep" are superficial discussions of philosophy/politics (see most of HN) or jargon-filled discussions of specific nerddoms that people are interested in.

karpierz··on The Lucretius Problem: How History Blinds Us
> That’s not how this works, anywhere: the burden of proof, of presenting facts, is on those who say “yes”.

What? Why? If this were true, you could:

1. Take the claim you want to assert

2. Claim the negation of the claim is false (the "no").

3. If anyone asks for facts, just say the burden of proof is on them to show the negation is true.

karpierz··on A Dialog in Real Time (Strategy)
I don't think the RTS genre died; I think it evolved. Two of the most popular games in the world, League of Legends and DotA2, are RTS games. The Total War franchise keeps on kicking. Auto-battlers like Teamfight Tactics and Mechabellum mix real-time analysis with turn-based decision making.

It's the old school style of RTS that's dying; harvest resources to build units and beat your opponent. But that style of game was perfected with the release of Brood War, and the core mechanics haven't been improved on since.

karpierz··on /u/spez is right about feudalism and that's why Reddit is doomed
> The majority of modern scholars avoid the term [Dark Ages] altogether due to its negative connotations, finding it misleading and inaccurate. Despite this, Petrarch's pejorative meaning remains in use, particularly in popular culture, which often simplistically views the Middle Ages as a time of violence and backwardness.

https://en.wikipedia.org/wiki/Dark_Ages_(historiography)

It's named the Dark Ages because 11th century scholars wanted to feel like their time period was enlightened and great compared to the past, not because there was some deep, thoughtful analysis.

karpierz··on /u/spez is right about feudalism and that's why Reddit is doomed
It's worth reading in a little more detail.

One of the core points is that "Feudalism" as used outside of academic discussion loses its semantic meaning beyond being a synonym for "oppressive". And so trying to discuss when feudalism starts inevitably falls into a discussion of "when did Europe get oppressive".

karpierz··on US public debt projected to reach 181% of economic activity in 30 years
Given that society has relied on fractional reserve banking since the 1600s, what is the alternative banking process you had in mind?
karpierz··on Releasing an indie game on 3 consoles at once and failing financially (2016)
If you want to make a game, it's never been easier! Download Unity, download a bunch of free sounds/textures/models/etc, and then write some simple code to your things around.

If you want to make a movie, it's never been easier! Grab your smartphone, write a script, grab some friends and have them read it, then post.

But from experience, actually making something passible (much less "good" or "great") takes years of dedicated practice, which is more accessible thanks to the above, but still doesn't really make the years any shorter.

Can you point to some great movies that didn't see any success this year?
karpierz··on Releasing an indie game on 3 consoles at once and failing financially (2016)
Analogously:

I wonder if many of the low budget films, especially narrative focused films, might be better off as games. Given how everybody has a computer these days, AAA games are formulaic garbage and games aren't centered around a single developer any more, there's probably a market for innovative low budget games made in a basement on a single computer by a few friends and with little to no art assets. That seems like it'd be lower time/money cost and higher expected reward than movie production, plus you'd get to spend time on the internet researching interesting technical problems rather than just sitting in a movie editor for years, working on a movie that will most likely be watched by a few dozen people.

tl;dr: I don't think a good movie is any easier to make than a good game.
