PS5 games ported to PC — no emulator involved

AnyPS5 relinks a PS5 executable into a native Windows or Linux binary.
No console emulator runs underneath it.

Native relinker — rewrites the PS5 executable into your OS's own binary format

System libraries, reimplemented — PS5 prx libraries rebuilt for dynamic linking

No emulator, no runtime — the ported game just runs, nothing emulated underneath

Shaders to SPIR-V — its recompiler turns PS5 shaders straight into Vulkan

Young and rough — one verified game at a stable 60 fps, 110 open issues

How AnyPS5 actually runs a PS5 game

The tool itself is free and GPL-2.0 licensed — there's no model, no API key and no paid service involved anywhere in the pipeline.

AnyPS5 is a relinker plus a set of reimplemented PS5 system libraries (the "prx" libs, in core/libs/prx). The relinker converts a PS5 executable into a native Windows or Linux binary; the libraries handle dynamic linking so nothing is emulated and no separate runtime process sits underneath the game.

Its shader recompiler turns PS5 shaders into SPIR-V for Vulkan, validated against Spirv-Tools when built with the ANYPS5_ENABLE_SPIRV_TOOLS flag.

The project's own compatibility notes list Dreaming Sarah, a 2D platformer, running a stable 60 fps on a GTX 1050 Ti with an i5-7500 — the only hard number in the README, the authors' own measurement, not independently checked.

Requires: your own legally obtained PS5 game files — the project ships no firmware, keys or proprietary libraries. No prebuilt releases: clone and build from source following BUILD.md.

git clone https://github.com/boykopovar/AnyPS5
cd AnyPS5

SDL-mapped controllers work out of the box; keyboard and mouse need an anyps5-input.ini file.

The catch: it's early. Unsupported code paths throw std::runtime_error and the process just quits, and the tracker already has 110 open issues. The verified-games list is still short.

Use it instead of a full PS5 emulator when your game is already on that compatibility list and you want native speed. Don't use it if your game isn't verified yet — it will most likely just error out.

Your workout log doesn't need someone else's cloud

openGym is a self-hosted gym and workout tracker: plan, log and track muscle recovery, all on a server you run yourself.

Your own server — instead of a subscription app's cloud, it runs where you host it

Clone and compose — git clone, set up .env, then docker compose up

Plan the week — a routine per weekday, with supersets, warm-ups and cardio

Muscle map — see what's trained, fatigued, or detrained

Guided and imported — weights pre-fill, a rest timer runs, history imports from FitNotes, Strong or Hevy

Self-hosted, not just open-source

openGym plans a routine per weekday from a library the project lists at 1,324 exercises, logs supersets, warm-ups, drop sets and cardio, then maps which muscles are trained, fatigued or detrained. Guided sessions pre-fill last session's weights and run a rest timer; it imports history from FitNotes, Strong, Hevy (CSV or API key) and Apple Health weight exports.

The tool itself is free and AGPL-3.0 licensed, with no cloud account to pay for. An optional AI coach can draft routines, but it needs your own key for Anthropic, OpenAI, Gemini, or a local Ollama model to avoid any per-use cost — that part isn't free unless you run it locally.

Requires: Docker with Compose, and a server or machine to run it on. Passkey login from a phone needs HTTPS on a domain too, a two-line .env change, with guides for Cloudflare Tunnel, Caddy, Traefik or nginx.

The catch: this is self-hosting, not an app-store install — you keep the server running yourself, and first start downloads about 140 MB of exercise media.

To try it: git clone https://github.com/DuarteSantos8/openGym, then cd openGym && cp .env.example .env && docker compose up -d. There's also a hosted demo with example data if you want to look before installing anything, and an Android APK on the Releases page.

Use it instead of a paid tracker subscription when you want your logs in your own folder; don't use it if you'd rather not run a server at all.

Redis's creator just built a 284-billion-parameter AI engine in a week

One Mac, one week, one engine. DS4 runs DeepSeek V4 Flash — normally a cloud-only model — fully offline, on hardware you already own.

One-week build — antirez (Redis's creator) wrote DS4 from scratch in about seven days

284 billion parameters — DeepSeek V4 Flash, a model that normally needs a datacenter

Fully offline — runs entirely on your own Mac, GPU box or mini-PC, no cloud calls

Uneven quantization — squashes barely-used experts hard, keeps core layers sharp

126 tokens/sec aggregate — the README's own number, across 16 concurrent sessions

How DS4 fits a frontier model on your desk

DS4 (also called DwarfStar, or ds4.c) is not a general framework — it's a single-purpose engine antirez wrote for one model family: DeepSeek V4 Flash/PRO, V4.1 Flash, GLM 5.2/5.3, and Qwen 3.8 Flash Next. It doesn't reuse llama.cpp's code but borrows its GGUF quantization ideas, under MIT license.

The trick is an asymmetric 2/8-bit quant recipe: routed experts, which make up most of the 284B parameters, get squashed to IQ2_XXS/Q4_K since each expert only ever handles a fraction of tokens — while attention, shared experts and output layers stay at sharper Q8_0.

The published GGUF conversion is 284B total: the Q2 quant is 80.8GB and fits 128GB-RAM Macs, the Q4 quant is 153.3GB and needs 256GB+. The 126 tokens/sec aggregate figure is the project's own README benchmark, measured on an 8xL40S GPU setup across 16 simultaneous sessions, not one fast single stream.

Everything here is free and MIT-licensed — the engine and the published weights on Hugging Face — so the real cost is the hardware, not a subscription or API key.

Requires: Apple Silicon Mac (Metal), or an NVIDIA GPU like DGX Spark/Ada-Lovelace (CUDA), or AMD Strix Halo (ROCm); 96-128GB RAM for the lightest quant, 256GB+ for heavier ones.

The catch: it only runs this handful of model families, and demands serious RAM or GPU muscle — this is not laptop-tier hardware for most people.

To try it, clone and build for your backend, then pull weights separately:

git clone https://github.com/antirez/ds4
cd ds4 && make

Weights: huggingface.co/antirez/deepseek-v4-gguf

Use it instead of a cloud API when you own the RAM and want zero per-token cost. Don't use it if your machine has consumer-grade memory, or you need the broader model support llama.cpp offers.

Reverse engineer any app, then build the feature yourself

You spot a feature you like in an app with no source code. Rea connects your coding agent to reverse-engineering tools so it can open that app, explain the feature, and help you build your own version of it.

Spot a feature, want it — ask your agent to investigate, no source code needed

Any target — native binaries, JavaScript and Electron apps, .NET, even websites

Ask in plain English — it decompiles the app and traces the code behind a feature

Evidence included — shows the clues and the trail it followed, not just a conclusion

From insight to code — turns what it learned into a feature inside your own project

How it works, and what it needs

Rea gives your coding agent a set of reverse-engineering tools over MCP, and the same tools work from your terminal. It decompiles the target, recovers readable code, strings and names, then follows that trail across the app until it can explain how a feature works — with the evidence attached, not just a verdict.

Rea itself is free and MIT-licensed. It runs inside the agent you already have — Claude Code, Cursor, Codex, Gemini CLI, Windsurf and others — so you still pay for whatever model access that agent uses. Rea doesn't add its own API bill.

Requires: macOS 12+, or Ubuntu 24.04+ / Fedora 41+ / 64-bit Arch Linux; Node.js 22.19+, 24.11+ or 26+; npm. Native binary analysis needs Hopper or Ghidra installed separately — Hopper's free demo runs under vendor-set limits, Ghidra is free but you install and point Rea at it yourself. Windows support via Ghidra is experimental and covers x86-64 PE apps on local NTFS only.

The catch: without Hopper or Ghidra, native binaries are off the table — JS, Electron, .NET and web targets don't need them. The project also says it doesn't recover original source or auto-clone an app; it explains and rebuilds, evidence attached.

Try it with npx rea-agents setup, which walks through connecting your agent and, on macOS, can install Hopper with your approval. A plain CLI install is npm install --global rea-agents then rea setup.

Use it instead of opening Hopper or Ghidra cold when you want an agent to drive the trace and explain it in English. Skip it if you need guaranteed source recovery rather than a reconstructed, evidence-backed feature.

REA vs ida-pro-mcp

Both wire an AI agent to a decompiler over MCP so you can ask how a feature works and get traced evidence for the answer; REA pairs free Hopper/Ghidra-driven native analysis with JavaScript, Electron, .NET, and website support in one guided setup, while ida-pro-mcp hands the same questions to IDA Pro's decompiler and debugger.

Pick REA if you want one agent workflow spanning native binaries, JavaScript/Electron apps, .NET assemblies, and websites without buying a decompiler license

Pick ida-pro-mcp if you already own IDA Pro and want its best-in-class decompiler and debugger driven by an agent, for native-binary work only

Price & Licensing
REA — free OSS; Hopper/Ghidra optional
ida-pro-mcp — free tool; needs paid IDA Pro

Setup & Integration
REA — one npx wizard, 12 agents
ida-pro-mcp — manual setup, 20+ MCP clients

Analysis Scope
REA — native bins + JS/Electron/.NET/web
ida-pro-mcp — native binaries only, via IDA

Limits & Maturity
REA — still needs Hopper or Ghidra
ida-pro-mcp — author now favors Hex-Rays' MCP

Side by side, in full

Price & Licensing
REA itself is MIT-licensed and free, and it can drive the free NSA tool Ghidra for native binaries, so the only cost most users add is Hopper's optional one-time $99 personal license (its demo blocks saving and exporting).
ida-pro-mcp itself is free and MIT-licensed, but it explicitly does not support IDA Free, so using it for real work means an IDA Pro subscription starting at €1,099/year (Essential) and rising to €8,599/year (Ultimate).

Setup & Integration
REA: A single `npx rea-agents setup` command configures REA's MCP access and workflow across 12 supported agents, including Claude Code, Cursor, and Codex, and can even install Hopper for you after you approve it.
ida-pro-mcp has no bundled installer: you must already own and install IDA Pro yourself, then manually point its Python MCP server at whichever of its 20-plus listed clients you want to use.

Analysis Scope
REA's catalog covers native binaries via Hopper or Ghidra plus JavaScript, Electron, .NET assemblies, and live websites, feeding one guided workflow that explains a feature and helps you rebuild it.
ida-pro-mcp exposes IDA Pro's decompiler, debugger, patching, type-inference, and cross-reference tools for native binaries only, with no built-in support for JavaScript, Electron, .NET, or websites.

Limits & Maturity
REA: Native-binary analysis in REA still leans on a separately installed Hopper or Ghidra, and its Windows path via Ghidra is explicitly an experimental, read-only slice covering just 25 inventory and function operations.
ida-pro-mcp requires a paid IDA Pro license since IDA Free isn't supported, and its own README now tells users to prefer the official Hex-Rays IDA MCP Server over this community project.

macOS 27 won't let you turn off Apple Intelligence. This CLI does, and deletes the models too.

A one-command, open-source Swift tool switches off Apple Intelligence on macOS 27 and clears the disk space its models leave behind — fully reversible.

One command, no toggle hunt — turns off Apple Intelligence and deletes its models

Full breakdown — removemacai status lists each feature's model size on disk

Blocks the comeback — stops macOS downloading those models again

No phone home — makes no network requests and collects no data

Fully reversible — removemacai revert undoes everything

What's actually happening under the hood

RemoveMacAI installs a configuration profile that applies Apple's restriction keys for Apple Intelligence and forces the settings that have no restriction key. Models are removed through Apple's asset service — System Integrity Protection stays enabled, and nothing under /System is touched directly.

The same profile redirects any model download to a closed local port, so macOS can't fetch them again. Removing the profile (via revert) restores the previous settings, and macOS downloads the models again once a feature needs them.

The tool itself is free. It makes no network requests and collects no data — there's no model or API key involved, since it only deletes files and flips settings, nothing to pay for.

The "frees over 12GB" figure comes from Reddit discussion, not a benchmark the author or this channel ran.

Requires: Apple silicon, macOS 27 (tested on 27.0; on 27.0.1 use version 0.2.3 or later). macOS 26 and earlier are not supported.

The catch: Apple Silicon and macOS 27 only, and the release binary is ad-hoc signed but not notarized, so Gatekeeper blocks a browser-downloaded copy until you clear the quarantine flag yourself.

Install:

curl -fsSL https://raw.githubusercontent.com/omlahore/RemoveMacAI/main/install.sh | bash

or brew install omlahore/tap/removemacai. Use --keep <features> to leave some on, and removemacai revert to undo everything.

A Photoshop clone that never saw Adobe's code

The video shows PhotoCraft: an open-source Photoshop rebuild in pure Rust, with real PSD files and a GPU compositor instead of a web view.

Clean-room Photoshop clone — built from scratch, no Adobe code

Native, not a web app — GPU compositor in Rust, no Electron

Real PSD files — layers, masks, type and vectors round-trip

Local smart selection — object selection on-device, no cloud

Scriptable by design — every action is a command, agents included

What's actually in PhotoCraft

PhotoCraft is a clean-room reimplementation of Photoshop: the team never looked at Adobe's source, and rebuilt layers, masks, adjustment layers, layer styles, type, vector shapes and brushes from scratch in Rust.

It opens and saves real PSD files. The project's own test suite reports that re-saving keeps the same render for 307 of the 309 files in the psd-tools test corpus — their number, not an independent benchmark.

Rendering runs on a GPU compositor built on wgpu (Metal, Vulkan, DX12, WebGPU) with copy-on-write tiles, instead of Electron or an embedded browser.

Selections go beyond marquees and lassos: Quick Selection, Object Selection and Select Subject run locally, with no cloud call and no account.

Every action is also a command, reachable from the CLI, a JSON control channel or an MCP server, so a script or an agent can drive the same engine as the UI. Automation now needs file-access roots you explicitly grant, plus a startup token.

Requires: macOS, Windows, Linux, FreeBSD or a WebGPU-capable browser, and a GPU for the Metal/Vulkan/DX12/WebGPU backends; the README lists no specific VRAM or CPU numbers.

The catch: this is early alpha, by the project's own label — expect rough edges before it's a daily driver.

The app is free and MIT/Apache-2.0 licensed; editing and smart selection run on your machine, so there's no API key or cloud bill involved.

Use it instead of a Photoshop trial or GIMP when you want a native, scriptable PSD editor you can automate offline. Don't reach for it yet if you need a stable release or Adobe plugin compatibility.

The README shows no single install one-liner; clone the repo and build the Rust workspace with Cargo:

git clone https://github.com/storytold/photocraft
cd photocraft
cargo run --release

722 math manuscripts, almost none written by a human

A GitHub repo full of AI-generated proofs, from one unreleased OpenAI model.
It's called Math — a public, checkable paper trail for machine mathematics.

722 manuscripts — OpenAI's public collection of AI-written math

4,000 problems, one model — each result cost ~3 hours of ChatGPT Pro compute

372 families — every result sorted into its own mathematical discipline

Reasoning included — abridged summaries of the model's own thinking, for select results

Not all formalized — some unformalized results could still have issues

What's actually in the repo

Math is OpenAI's release of manuscripts and proof artifacts produced by an internal, unreleased model, evaluated on open research problems after the existing math evals saturated.

The vast majority followed one fixed procedure: the model was posed about 4,000 problems, and each result used on average three hours of ChatGPT Pro thinking compute. Those figures are OpenAI's own account of how the collection was made, not an independent measurement.

The output aggregates into 372 families across 722 manuscripts, each family classified by discipline. Ten families — covering results like the irrationality exponent of pi and Kaplansky's direct-finiteness conjecture — ship with abridged summaries of the model's reasoning.

A few exceptions sit outside that procedure: the zero-free region for the Riemann zeta function and the Hodge Conjecture proof for CM abelian varieties, plus one zeta-function writeup that was human-edited for readability.

The tool is free: it's a static collection of PDFs, source files and proofs, nothing to run and no API key needed to read it.

To try it:

git clone https://github.com/openai/math.git

then open overview.pdf for family descriptions, CONTENTS.md for the manuscript map, and browse preprints/.

Requires: a Lean toolchain only if you want to check the formalizations under lean/; the project names no GPU, OS or other hardware requirement for browsing the rest.

The catch: many, but not all, manuscripts have a Lean formalization backing them. OpenAI says some unformalized results could still have issues, to be fixed as they're found.

Use it instead of just asking an LLM for a proof when you want a public, checkable trail. Don't use it if you need fully verified math — plenty of entries still lack formalization.
