BizHawk
BizHawk is a multi-system emulator written in C#
A multi-system emulator written in C#. As well as quality-of-life features for casual players, it also has recording/playback and debugging tools, making it the first choice for TASers (Tool-Assisted Speedrunners). Screenshotting and recording audio + video to file. Firmware management, input, framerate, and more in a HUD over the game. Rebindable hotkeys for controlling the frontend (keyboard+mouse+gamepad). A comprehensive input mapper for the emulated gamepads and other peripherals. Programmatic control over core and frontend with Lua or C#.NET. Development builds are made automatically whenever someone contributes. Because of this, we recommend using a release for work that requires stability (such as TASing), and only switching to a dev build if there's a specific change or addition you need. -

idevicerestore
Restore/upgrade firmware of iOS devices
A command-line application to restore firmware files to iOS devices. The iDevice restore application is a full reimplementation of all granular steps which are performed during the restore of firmware to a device. In general, upgrades and downgrades are possible, however subject to the availability of SHSH blobs from Apple for signing the firmware files. idevicerestore requires a properly installed usbmuxd for the restore procedure. Please make sure that it is either running or configured to be started automatically as soon as a device is detected in normal and/or restore mode. If properly installed this will be handled by udev/systemd. -

QP Real-Time Event Frameworks & Tools
Real-Time Event Frameworks based on active objects & state machines
QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows. -

UACMe
Defeating Windows user account control
Run executable from command line, akagi32 [Key] [Param] or akagi64 [Key] [Param]. First parameter is a number of methods to use, second is an optional command (executable file name including full path) to run. The second parameter can be empty - in this case, the program will execute elevated cmd.exe from the system32 folder. Since 3.5.0 version all "fixed" methods are considered obsolete and removed altogether with all supporting code/units. If you still need them. This tool shows ONLY popular UAC bypass method used by malware, and re-implement some of them in a different way improving original concepts. There are different, not yet known to the general public, methods. This tool is not intended for AV tests and not tested to work in aggressive AV environment, if you still plan to use it with installed bloatware AV soft, use it at your own risk. -

AWS IoT Device Shadow library
Client library for using AWS IoT Shadow service on embedded devices
The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a JSON document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its state. Each device’s shadow is uniquely identified by the name of the corresponding “thing”, a representation of a specific device or logical entity on the AWS Cloud. See Managing Devices with AWS IoT for more information on IoT "thing". More details about AWS IoT Device Shadow can be found in AWS IoT documentation. This library is distributed under the MIT Open Source License. -

Skynet
A lightweight online game framework
Skynet is a lightweight online game framework which can be used in many other fields. Skynet is a lightweight framework designed for online game servers. Although from the feedback of the Community , it's not limited as a game server framework. On the Uses page, it shows a few projects that have used or currently using Skynet, but there are way more projects than listed. And welcome to be the next user. For Linux, install autoconf first for jemalloc. For FreeBSD , use gmake instead of make. Skynet now uses a modified version of lua 5.4.2 for multiple lua states. Official Lua versions can also be used as long as the Makefile is edited. With Socket API and SocketChannel , which makes it easier to implement socket pool and reconnect, you can use Skynet to call socket even asynchronously. Skynet doesn't force a specific protocol, you can come up with your own design. -

TrustKit
Easy SSL pinning validation and reporting for iOS, macOS, tvOS
TrustKit is an open-source framework that makes it easy to deploy SSL public key pinning and reporting in any iOS 12+, macOS 10.13+, tvOS 12+ or watchOS 4+ App; it supports both Swift and Objective-C Apps. Simple API to configure an SSL pinning policy and enforce it within an App. The policy settings are heavily based on the HTTP Public Key Pinning specification. Sane implementation by pinning the certificate's Subject Public Key Info, as opposed to the certificate itself or the public key bits. Reporting mechanism to notify a server about pinning validation failures happening within the App, when an unexpected certificate chain is detected. This is similar to the report-uri directive described in the HPKP specification. The reporting mechanism can also be customized within the App by leveraging pin validation notifications sent by TrustKit.
