Fedify is an ActivityPub server framework in TypeScript & JavaScript. It aims to eliminate the complexity and redundant boilerplate code when building a federated server app, so that you can focus on your business logic and user experience.

The key features it provides currently are:

• Type-safe objects for Activity Vocabulary (including some vendor-specific extensions)
• WebFinger client and server
• HTTP Signatures
• Middleware for handling webhooks
• NodeInfo protocol
• Node.js, Deno, and Bun support

If you're curious, take a look at the Fedify website! There's comprehensive docs, a demo, a tutorial, example code, and more.

It's sort of a different concept. Posts and users also have position in addition to age and score. The sorting algorithm gives you complete control over how much to weight each one. It's like if new and hot existed on a continuous spectrum. It's sort of like what Aaron Swartz initially wanted to do with Reddit where what you like would be able to inform what you might like in the future. But in this case you get complete control over how much that matters.

I'm adding bits and knobs here and there every day. Yesterday I added the ability to have posts that are hidden from the front page. It's probably not a feature people will use every day but it's there if someone wants it and it's things like that I'm working on every day. In a little bit I'm going to add a "post whenever" feature in case someone wants to post a ton of content and have it actually post over time.

I'd say all and all the project has been a success for what I wanted to do with it and I'm happy with what I've built. The other side of it is trying to build community on the site. For example we do a movie night once a week on Saturdays.

Oh. Another thing that is different to most reddit clones is that every community exists. Like you don't have to create a community to post to it. Just post to it. Different capitalization maps to the same community.

You guys should check it out. It would be super awesome if anynone wants to help fill in the more obscure topics.

About this Book

The Rust programming language is extremely well suited for concurrency, and its ecosystem has many libraries that include lots of concurrent data structures, locks, and more. But implementing those structures correctly can be difficult. Even in the most well-used libraries, memory ordering bugs are not uncommon.

In this practical book, Mara Bos, team lead of the Rust library team, helps Rust programmers of all levels gain a clear understanding of low-level concurrency. You’ll learn everything about atomics and memory ordering and how they're combined with basic operating system APIs to build common primitives like mutexes and condition variables. Once you’re done, you’ll have a firm grasp of how Rust’s memory model, the processor, and the role of the operating system all fit together.

With this guide, you’ll learn:

• How Rust's type system works exceptionally well for programming concurrency correctly
• All about mutexes, condition variables, atomics, and memory ordering
• What happens in practice with atomic operations on Intel and ARM processors
• How locks are implemented with support from the operating system
• How to write correct code that includes concurrency, atomics, and locks
• How to build your own locking and synchronization primitives correctly

Available free of charge. But I doubt I'll ever read it. Never enough time and energy for everything.

Up until now, every user on the network used a Bluesky PDS (Personal Data Server) to host their data. We’ve already federated our own data hosting on the backend, both to help operationally scale our service, and to prove out the technical underpinnings of an openly federated network. But today we’re opening up federation for anyone else to begin connecting with the network.

The PDS, in many ways, fulfills a simple role: it hosts your account and gives you the ability to log in, it holds the signing keys for your data, and it keeps your data online and highly available. Unlike a Mastodon instance, it does not need to function as a full-fledged social media service. We wanted to make atproto data hosting—like web hosting—into a fairly simple commoditized service. The PDS’s role has been limited in scope to achieve this goal. By limiting the scope, the role of a PDS in maintaining an open and fluid data network has become all the more powerful.

We’ve packaged the PDS into a friendly distribution with an installer script that handles much of the complexity of setting up a PDS. After you set up your PDS and join the PDS Admins Discord to submit a request for your PDS to be added to the network, your PDS’s data will get routed to other services in the network (like feed generators and the Bluesky Appview) through our Relay, the firehose provider. Check out our Federation Overview for more information on how data flows through the atproto network.

For a very small instance with only a couple of concurrent users a CDN might not make much difference. But if you take a look at your web server logs you’ll quickly notice that every post / like / vote triggers a storm of requests from other instances to yours, looking up lots of different things. It’s easy to imagine how quickly this would overwhelm an instance once it gets even a little busy.

One of the first web performance tools people reach for is to use a CDN, like Cloudflare. But how much difference will it make? In this video I show you my web server logs before and after and compare them.
