Hey HN,

This is a full open-source rewrite of The Sound of Sorting — the classic algorithm visualizer — built entirely in Swift with SwiftUI for macOS and iPadOS.

Originally intended as a straight port, it quickly became a much deeper project: a ground-up redesign focused on code quality, educational value, and cross-platform Apple support.

Highlights:

Real-time visual and audible sorting animations

Detailed explanations of each algorithm

Time & space complexity breakdowns

Code implementations in 10 different languages (and growing)

A fully custom syntax highlighter written in Swift

Modular architecture for adding new algorithms or languages easily

This has been my longest-running personal project — I started it in late 2021 as my first Swift app, and it’s now become a platform for exploring everything from AVFoundation to SwiftUI best practices.

Why I’m sharing: I’d love feedback, ideas, and especially contributions. There’s plenty of room for improvements: better performance, more algorithms, expanded language support, accessibility enhancements — you name it. Even reviewing the Swift code and helping improve the idiomatic use of the language would be hugely appreciated.

If you’re into open-source, visual learning tools, Swift, or just love making things better — I’d be thrilled to collaborate.

The code is available here: https://github.com/nhubbard/sort-visualizer-swift

And the app is available for download from the Mac and iPadOS App Store here: https://apps.apple.com/us/app/sort-symphony/id6477886990

Thanks!

I've been thinking about the idea of the prosocial economy, an economy where you're forced to use your money for public good, & which fuses communism & capitalism. There are 2 main ideas. The 1st is the split of accounts between private & public. The 2nd is total cashlessness.

Total cashlessness helps to eliminate crime, which depends on untrackable exchanges of money. & because cyberattacks are equally bad for both cashless & mixed economies (ex. half cash, half cashless), you might as well just switch over entirely to a cashless economy, & based on blockchain.

& private accounts work like your bank accounts today do, except they're wealthcapped at a reasonably high amount, & excesses go into the public account. Public accounts hold money that can only be used to either fund, make, or invest in companies belonging either to you or someone else. & money in public accounts can never go into private accounts except through company salaries. & there's equity but no stocks or bonds or real estate speculation in this economy. & nothing that's dependent on them, such as mutual funds or index funds.

The big idea is that in modern economies there's alot of dead money or value wrapped up in financially productive but physically or intellectually unproductive activities such as investing in stocks or bonds. & most people never use more than a few million dollars in their lives, so that excess money just ends up being useless. & so it's better to just softly force people to use that money to help or actually create physical & intellectual value.

There's probably a short essay of constraints that have to be added, such as not allowing people to buy commodities that aren't stored in banks with private accounts, or considering assets as part of accounts, or CCP style capital controls, or equity markets, but this is the gist of it.

(& I'm thinking there should be many restrictions on what people can buy with their private accounts, like in a command economy. But none on what people can buy with their public accounts, like in a free market economy. & that there should be subsidies for important but expensive private goods & services, paid for by the government. & I'm also thinking salaries should be capped, with CEO salaries being only twice as much as entry level jobs.) (& that public accounts should be transferred from underperformers to top performers by overwhelming majority votes, so something like 80% of the votes instead of 50%, & on a regular rolling basis. & some other ideas that involve making sure money is always put to use & for public good.) (& that people should get enough UBI to live alone, but not enough to have kids.)

I came up with this idea thinking over how to produce more Elon Musks. I also thought over the main flaw of communism, which is the inability to allocate wealth in a grassroots manner, & the main flaw of capitalism, which is the preponderance of useless & antisocial & cancerous hypergrowth.

Posts on Facebook’s website can have two types of URLs:

* with tracking: facebook.com/(user)/posts/(long obfuscated hash) * without tracking: facebook.com/(user)/posts/(short numerical ID) Here’s an example of a Facebook URL without tracking:

https://www.facebook.com/savezdodir/posts/1073504858142844/

If you go to https://www.facebook.com/savezdodir/, open that post (it’s the latest post), and then look at the URL, you will not see the numerical ID but an obfuscated hash that contains your information. So if you share that post (e.g. on Twitter) and other people click that link, Facebook will know that you brought them to Facebook.

When I’m viewing a post on Facebook’s website, how do I find that numerical ID? In other words, the non-tracking URL of that post.
