    Skynet

    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.

    omegalib

    omegalib

    Hybrid visualization framework for desktops, large immersive displays

    A hybrid visualization framework for desktops, large immersive displays and the web. A framework for virtual reality and cluster-driven display systems. Requires Python (the pre-installed 2.7 version on OSX and most linux distros works fine, on Windows omegalib comes with python bundled so you don't need this). C++ Build tools for your platform (g++, clang/XCode, Visual Studio 2012/2013 depending on the OS). On windows, the free Visual Studio editions work fine. Modules are optional components that extend omegalib functionality. Enabled modules are automatically downloaded and compiled. A full list of modules can be found in the Omegalib hub. On most platforms, omegalib is distributed as a source-only project. Users are responsible for creating binaries for their operating system and architecture. The build process is kept as simple as possible and should require very little configuration effort by the user. Omegalib can build out-of-the-box and has no external dependencies.

    BCC (BPF Compiler Collection)

    BCC (BPF Compiler Collection)

    Tools for BPF-based Linux IO analysis, networking, monitoring, etc.

    BCC is a toolkit that simplifies creating efficient kernel tracing, monitoring, and manipulation programs by leveraging extended Berkeley Packet Filters (eBPF). It includes a rich set of example tools and scripting interfaces in C, Python, and Lua. BCC makes BPF programs easier to write, with kernel instrumentation in C (and includes a C wrapper around LLVM), and front-ends in Python and lua. It is suited for many tasks, including performance analysis and network traffic control. With a BPF-specific frontend, one should be able to write in a language and receive feedback from the compiler on the validity as it pertains to a BPF backend. This toolkit aims to provide a frontend that can only create valid BPF programs while still harnessing its full flexibility.

    UACMe

    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.

    wxPHP

    wxPHP

    PHP bindings for the cross-platform GUI library wxWidgets.

    wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it.
