arc-in-space··on The infamous coin toss
Thanks, putting it this way does help me understand a bit better. So a large number of repeated fair tosses can be broken down into a sequence of win-loss pairs, which are always =0.9.

The thing that still confuses me is, why the heck is the EV 1.05? It seems to be expressing something true - if you were to split your money into a thousand piles and "play" each individually, you make money overall.

arc-in-space··on The worst API ever made (2014)
Same here. Trying to write something using win32 as a ~14yo made me feel like an absolute worthless idiot and I just didn't touch code for 2-3 years.
arc-in-space··on Show HN: LibreScroll – enable flywheel-scrolling on any generic mouse
I like it! No real use for me since linux + already have a g502 but I like the idea. This kind of momentum scrolling is already ubiquitous in phones and video games (probably Macs, too?) so I wonder why it otherwise hasn't caught on for viewing documents.
arc-in-space··on The US economy and the EU were the same size in 2008, the US is now nearly 2X
Eh, sure, but here it's worth pointing out that obesity is a significant factor in covid deaths.
arc-in-space··on Linux has achieved a 3% desktop market share
> The change from say one version of Windows to the next is tiny

Huh?! That's bullshit. I had recently tried to fix something on family's PC that upgraded itself to Win11 and had absolutely no clue how to navigate all the new settings panels even though I use 10 near daily.

arc-in-space··on Civic honesty around the globe (2019)
Thank you for the response! I did miss the supplementary material notes.
arc-in-space··on Civic honesty around the globe (2019)
My main takeaway is to keep a bit of cash and an email adress in a wallet. Also, I have to wonder how much the fact that the assistants would have been perceived as foreigners in most of these countries skews the results.
arc-in-space··on Why Nvidia Keeps Winning
ROCm is a disaster. It doesn't even work with most AMD GPUs, and the software is awful(difficult to setup, very poorly supported). AMD keeps occasionally releasing new stuff in the GPGPU space, then leaves it unsupported and continues to fall further behind Nvidia.
arc-in-space··on Bret Victor update
When I first saw Dynamicland I assumed it'd quietly evaporate within a month, I'm glad to hear it's still being built.
arc-in-space··on Tech companies keep falling for the forever fallacy
It's not that they specifically want less people to do work, rather, high employment is a symptom of an overheating economy in which hiring is (for now) cheap and it's difficult to replace people and meet high demand, because most people who would be looking for a job already have one.
arc-in-space··on Debian 12 'Bookworm' New Features and Release Date
For what it's worth, Debian and Ubuntu are similar enough that a lot of the troubleshooting people post online for Ubuntu tends to work with Debian, too.
arc-in-space··on Apple’s new headset meets reality
I suppose he must mean touchscreens? Which are about as inhuman as it gets.
arc-in-space··on Asus Ally Emulates PS3, Nintendo Switch, Xbox 360 with Ease
This isn't the same SteamOS as the one that the Deck is running, it's an old one from their Steam Machines. Valve should take that page down or put up some sort of warning as it's been confusing people.
arc-in-space··on Ocean Temperature
For the exact same reason people post links to other things, it's interesting. It's always been more "hacker" than "news" here.

Incidentally, check out this wacky alien-looking worm that exhibits bioluminescence even though it lives its entire life inside of a tube, so there is no one to perceive it: https://en.wikipedia.org/wiki/Chaetopterus

arc-in-space··on My thoughts on OCaml
Sorry, I initially wrote 'interfaces as in OOP' to distinguish them from module interfaces, but had 'ad-hoc polymorphism' in mind. 'interfaces' is much too overloaded of a term.
arc-in-space··on My thoughts on OCaml
Someone mind explaining how these help? I'm unfamiliar with OCaml, but looking at the documentation of modules, I don't understand what they have to do with interfaces in the OOP sense(EDIT: or, rather, ad-hoc polymorphism), which I'm pretty sure is what the author meant.
arc-in-space··on Rust vs. Haskell
Copy-on-write generally refers to copying everything on every write; this is a persistent data structure, which can do updates while only copying a small part of itself. Same purpose as COW, but more efficient for larger data structures we want to make lots of small updates on.
arc-in-space··on Tether ownership and company weaknesses revealed in documents
>If you disagree, there are instruments with which you can express said disagreement and earn a profit for being correct.

What, in crypto? I thought no one in their right mind dares short this stuff due to counterparty risks.

arc-in-space··on Ain't it funny how the knight moves?
I suppose you win the 10000 IQ award for being the only person on the website to realize?
arc-in-space··on Sudoedit can edit arbitrary files
goto to a cleanup/error handling block at the end of a function is a fairly common C idiom
arc-in-space··on Explore Wikipedia's New Look
Unfortunately this only works if you have javascript enabled on the site, too, and the awful popups they added made me disable it.
arc-in-space··on A stack of feed-forward layers does surprisingly well on ImageNet
Not at all, if you're thinking of the forward-forward stuff
arc-in-space··on A Guide to the Terminal, Console, and Shell
As in, the screen is the part that makes it a video terminal, as opposed to the ancient printer terminals.

(Also, what do you mean "casually states"? There's a long section detailing the history of the terminal right in the article, am I misunderstanding your question?)

arc-in-space··on Corkscrew optics yield direct line to electronics

arc-in-space··on SEC set to propose rules that would squeeze stock-market middlemen
I agree, but also, maybe some amount of punching down is deserved - there really does tend to be a lot of people speaking in an authoritative tone while being completely wrong in the finance-related hn threads

EDIT: I suppose we can scratch the "finance-related" bit

arc-in-space··on Ask HN: If I get locked out of everything, please try to help me
It seems possible to disable this by manually logging out of all your devices in google account management, then never using them to log into your google account again. I've done that, but the fact that this is the only solution is unbelievably insane.
arc-in-space··on Ask HN: Developer abused “sign in with GitHub”?
Whoa, I'm very surprised at the amount of "told you so" and blaming the user in this thread. How many times are we going to retread the same tired arguments in this industry? Not everyone who uses github and other SSO sources is a elite hacker that knows exactly what the buttons they're pressing mean, plus sometimes we just make dumb mistakes. At the very least github should make it much higher friction to give a third party access to fuck with your account, and only make it dead simple to act as a identity provider.
arc-in-space··on I gave ChatGPT the 117 question, eight dimensional PolitiScales test
A lot of these questions are infuriating.

"Offshoring and outsourcing are necessary evils to improve production."

This one can be took to imply that offshoring is evil regardless of whether you agree that it's necessary or not.

"A language is defined by its users, not by scholars."

This shouldn't even be considered a political question.

EDIT: Don't bother with that quiz, it's clueless.
