Zagitta/gpu-unlock

A Linux kernel module unlocks hidden BF16/FP16 speed on RTX 3000 GPUs — This kernel module combines the CMP unlocker's V67/PLM technique with UEFI-style pre-driver timing to double FP/BF16 FMA throughput on GA102/103/104/106 GeForce cards, without patching NVIDIA's driver each release. Benchmarks show BF16 GEMM gains of 25-80% depending on the card, useful for anyone running ML workloads on consumer RTX 3000 GPUs.

Your GeForce runs AI at half speed. This fixes it for 20/30/40 series cards. Up to 2× FP16 / BF16 / TF32 tensor throughput

JustAResearcher/gpu-unlock-ada

A Linux kernel module that roughly doubles RTX 4090 tensor throughput — This Linux kernel module overrides the SM speed-select register before NVIDIA's driver loads, unlocking FP16/BF16 tensor throughput on RTX 4090 (and experimental RTX 4070 Ti SUPER) GPUs. Reported measurements show ~2x gains (e.g. 165→331 TF/s) that survive FLR and driver reinit, with matched evidence and limits documented across multiple independent runs.

otya128/winevdm

Run 16-bit Windows apps natively on modern 64-bit Windows — WineVDM ports Wine's 16-bit Windows virtual DOS machine to 64-bit Windows, where Microsoft's own NTVDM can't run since LDT modification is blocked. It bundles a CPU emulator, Win16-to-Win32 relay code generated via convspec, DOS emulation, and handle conversion, letting old Win16 executables run directly after install.inf registers them as native-feeling apps.

facebookincubator/muse-gadget-sdk

Facebook opens the SDK behind DIY Muse smart-home gadgets — This SDK lets hobbyists turn ESP32 boards or a spare Raspberry Pi/Linux box into custom Muse gadgets, wiring up screens, sensors, or actuators. It supports streaming phone camera feeds to ESP32 screens via H.264/VP8 and includes AGENTS.md files for coding agents, making it approachable for both hardware tinkerers and AI-assisted development.

EthanArbuckle/fairplay-decrypt

Decrypt FairPlay-Protected IPAs Without a Live Device Connection — This tool decrypts FairPlay-encrypted App Store IPAs offline using a 16-byte account credential, deriving page keys itself from SINF/SUPF records rather than relying on a jailbroken device at decrypt time. It supports version-3/5 SUPF and both 440- and 448-byte SINF priv records, running on macOS and Linux, useful for researchers needing offline arm64 binary analysis.

oosexgang/hakios-xnu-kernel

Booting Apple's actual XNU kernel and iOS 16.5 userspace on a Snapdragon Android phone — HackiOS runs Apple's open-source XNU kernel (from iOS 16.5) with the unmodified iOS userspace — launchd through SpringBoard — on a POCO X5 Pro 5G or QEMU, using a custom EFI loader, UEFI port, and a Linux Wi-Fi compatibility layer instead of Apple's closed drivers. No Apple files are bundled; IPSW content is fetched directly from Apple's CDN. A striking project for OS porting and reverse-engineering enthusiasts.

notaroomba/keybytes

A keyboard where every key is its own rearrangeable PCB module — Keybytes is an open-hardware keyboard project where each key, called a Keybit, has its own CH32V003 RISC-V chip and connects via pogo pins on all four sides, letting keys be freely rearranged and held together with magnetic cases. A separate Keyword board handles Bluetooth, USB-C and battery charging. Good read for hardware hackers into KiCad PCB design and modular input devices.
