I can't decide whether #Cpp #Asio is a terrible library or a great library with terrible documentation.It technically has all of the features you need for async I/O, without something heavier like libuv. And it technically has full documentation, but that documentation is as minimal as possible. I've mostly relied on Stack Overflow to find examples.But I've wasted *so much time* chasing down memory bugs from async callbacks in C++. It seems like C++20 coroutines could make things better?

@icedquinn For extra fun, try Gosper spiral coordinates--represent each hex with one number!Also known as spiral honeycomb mosaic: https://gamedev.stackexchange.com/questions/71785/converting-between-spiral-honeycomb-mosaic-and-axial-hex-coordinates(Someday I'll find the motivation to work on my hex-based Terraria clone engine again...)

@icedquinn Memory locality, mostly. If you store all of your hexes in a big 1D array in Gosper order then nearby hexes are usually nearby in the array.But also just because it's cool.

Every time I see the word "megacity" in a YouTube thumbnail, I pronounce it the way Megamind pronounces Metrocity.

@wjmaggos They could only serve as subreddits if combined with some form of moderation, like ATProto's third-party moderation system.

@wjmaggos - Using hashtags like groups would likely involve pulling in more of the social graph than a single server sees through follows alone; this goes beyond the scale a server admin could easily moderate.- What about single-user servers? Probably you'd need relays or other servers' feeds to get enough data to populate hashtags, and a lot of spam could come with that.- Collapsing tagged replies into threads, and viewing hashtags like a forum board, is a good idea though (Tapir feature? 🤔)

#Bluesky bridging is finally happening! Only opt-in, though, so make sure to follow @bsky.brid.gy if you want your posts to show up there.@snarfed.org, any chance you'd consider implementing FEP-fffd (https://codeberg.org/fediverse/fep/src/branch/main/fep/fffd/fep-fffd.md) on brid.gy? This was one of the primary use cases for it.

Java is an interesting language for a Fediverse project because it's the one language with several mature implementations of Semantic Web tech (RDF, SPARQL, etc). JSON-LD just works, out of the box. It was kind of shocking to see Apache Jena do in a few minutes of work what took me weeks in Deno!And I learned about a piece of the Semantic Web ecosystem I wasn't familiar with before. Have you heard the good word of OWL?#Fediverse #Java #SemanticWeb #RDF #JsonLD

@fasterthanlime probably needs both a move constructor and a move assignment operator, see the "rule of zero/three/five" (https://en.cppreference.com/w/cpp/language/rule_of_three), like most things in C++ it's verbose and tedious and you'd never know what you were doing wrong without reading about it first, but it does work if you're consistent.

@fasterthanlime of course there are some containers and smart pointers that just refuse to use a move constructor no matter what you do, but if you add move constructors and move operator=, then delete the copy constructor and copy operator=, you'll at least know for certain when this happens instead of having something copied silently.

@christopher I want something like this too; I've likewise been stuck with Obsidian but have considered writing my own. In addition to the features you mention, I'd want:- OneNote-style notes mixing text, handwriting, and images- Save web pages to your notebook, like what Evernote used to do- Organize by tags instead of folders- Use local AI to tag untagged notes, to save time- A good solution for free automatic sync that isn't Gitmaybe I'll write it someday...

@icedquinn If there were decent open-source tooling for ASN.1 that only supported a reasonable subset of its features, we would never have needed Protobuf.

@stpaultim As far as I know, it's the only bridge. It works pretty well, the main problems are 1. Hardly anyone on the Bluesky side is using it, and 2. Bluesky has a lot of protocol limitations (short post length, and no way to edit posts!) so bridged posts are often cut off or out of date.

@sun It's the only worthy successor to SimCity 4. It doesn't do everything right, but no one else (especially not EA) is even trying to make a basic city simulator that's actually good.The biggest problem is that it tries too hard to base everything around a very specific unrealistic kind of traffic sim, so once cities get big enough they usually start to fail because emergency vehicles keep getting stuck in traffic.
