BackToCatalina Restores the Classic Mac Look

BackToCatalina puts the familiar look of an older Mac back onto your newest machine. While Apple changes the design of every new system release, this tool snaps your Finder and core apps back to the style of Catalina, the version many people still prefer. It works across both Intel and Apple silicon Macs running the latest software. You simply install a package to apply the changes, and your desktop feels like it did years ago. It is a simple way to keep the interface you already know without giving up modern performance. If you miss the old look, this is how you get it back.

The One-Click Marketplace for Affinity Scripts

Download and install custom automation tools for Affinity Suite with a single click, bypassing the usual hassle of manually finding and running code. This project serves as the central backend for the Affinity Script Manager app, acting as a curated marketplace where community members can share helpful scripts that automate repetitive design tasks. The standout feature is its incredibly low barrier to entry: if you have written a script, you do not need to know Git or pull requests. You simply open an issue with your code and details, and once the maintainers approve it for safety, it instantly appears in the app for everyone.

Statistical Rethinking: The 2026 Course

Stop treating your data like a magic black box. Richard McElreath's Statistical Rethinking course flips the script, forcing you to build a causal theory before you touch a single number. The 2026 edition splits the training into two slower tracks, so you can actually absorb the material without burning out. You learn why most statistical estimates are just guesses until you define the assumptions behind them. It’s practical, not theoretical, focusing on real workflows that work in the messy real world. If you want to stop just crunching numbers and start understanding what they actually mean, this is the place to start.

How e2e Tests Apps With Words

e2e is the test framework that lets you drive apps with plain English. Usually writing tests means hard-coding every click, which breaks the moment the design changes. Here you just tell an AI agent your goal, like upgrade the account, and it figures out the steps to get there. The coolest part is that it records the path it took, so the next run is instant and costs zero money until the app actually changes. It works on both websites and mobile phones, letting you verify complex flows without writing brittle code. If you want tests that think for themselves, this is a game changer.

Yoagent: The Rust Agent Loop

yoagent gives your Rust code a brain that actually works. It connects to any major AI provider, lets the model run real commands like reading files or executing code, and keeps looping until the job is done. The coolest part? You can point it at a local model on your own machine, with zero setup and no API keys. It’s like having a private, offline coding assistant that lives right in your terminal. If you’ve ever wanted to build an AI agent in Rust without fighting with glue code, this is your starting line. Give yoagent a spin and watch your code come alive.

CalcKernel: A Language for Tiny, Fast Math

CalcKernel is a tiny, statically typed language designed specifically to write small, high-speed math routines that plug into larger apps. It handles the heavy lifting of numerical calculations while your main application manages the interface and data storage. What makes it genuinely interesting is its ability to compile your code directly into WebAssembly or native machine code, using advanced optimizations like vectorization to squeeze maximum speed out of your processor. You get a clear, typed boundary between your logic and the surrounding software, ensuring data stays safe and efficient.

PlayStation 1 Games Run Natively on Modern OSes?

A hundred and five classic PlayStation games now run natively on Windows, Linux, and Mac. This is a collection of official build kits, not emulators. You provide your own disc data and system file, and the kit compiles the code directly for your computer. It is a massive technical undertaking to make old hardware code run on modern chips without the usual emulation overhead. The catalog makes it easy to find what you need, complete with screenshots and specific notes on known issues. It is a fascinating look at how far retro porting has come.

Solo Founder Skills: Your AI Co-Founder

Turn your messy business ideas into working software by handing the reins to a set of specialized AI skills. Solo Founder Skills gives you a complete playbook for bootstrapping a product, covering everything from initial validation to final deployment. Instead of juggling ten different tools, you get a unified system that guides your coding agent through every step of the journey. The coolest part is the routing system, which tells the AI exactly which skill to use for your current task, saving you from context overload. It’s like hiring a team of experts but only paying for the advice you need right now.

Hillock: The Memory That Never Lies

Hillock is the local memory engine that refuses to guess. Most AI assistants make up answers when they do not know something, but Hillock uses a mathematical gate to block those questions before they reach the language model. It stores your documents in a compact graph and uses simple math to verify every fact. This means it runs on almost any computer without burning through your graphics card. If it does not have the answer, it tells you honestly instead of inventing one.

The Darkness Recomp: Play on PC, Native

The Darkness Recomp is the native port that finally lets you play the Xbox 360 classic on your PC without emulation. Instead of faking the old hardware, this project translates the game's code directly into modern C++ before you even launch it. The coolest part? It decodes your game files in memory using your computer's built-in security tools, meaning no shady third-party decryptors required. It handles everything from high-resolution rendering to controller support natively. So if you have the disc dump, you can jump right in. This is what real porting looks like when done right: clean, fast, and completely under your control. Give it a try.

Matryoshka: The LLM trick that saves 93% of your tokens

Matryoshka is the document analysis tool that lets small AI models process files a hundred times larger than their memory limit. Traditional AI tries to read entire massive files at once and instantly forgets half of them, but Matryoshka uses a clever trick where the AI only looks at tiny, compressed summaries of your data. It never reads the whole thing; instead, it asks for specific pieces only when it really needs to, storing the rest safely in the background. This means you can analyze huge server logs or codebases without expensive, massive context windows, and you get accurate answers without the model hallucinating missing details.

XiaoyaoSearch turns your local computer files into a searchable brain that understands spoken words and photos. Instead of typing complex keywords, you can simply talk for thirty seconds or upload an image of a chart or screenshot. The software uses artificial intelligence to translate that voice or visual clue into a deep search of your documents, videos, and audio files. It is built for people who want to find specific information without manually digging through folders. This tool bridges the gap between how we naturally ask questions and how computers store data. It gives you a conversational way to retrieve your own work.

Spirula Studio: Video to 3D in One Go

Spirula Studio is the 3D capture tool that turns plain video into a solid, usable mesh without forcing you to pick a graphics card brand first. It solves the headache of needing specific hardware for high-quality 3D reconstruction by running the entire training process on either Vulkan or CUDA. You simply feed it a video, and it builds a detailed Gaussian splat, then converts that into a clean mesh you can actually edit. The most surprising part is how it handles the heavy math for both major graphics ecosystems on the same machine. That means your laptop or desktop works, no matter which graphics chip it has.
