linuxdeployqt
Makes Linux applications self-contained by copying in the libraries
Makes Linux applications self-contained by copying in the libraries and plugins that the application uses, and optionally generates an AppImage. Can be used for Qt and other applications. This Linux Deployment Tool, linuxdeployqt, takes an application as input and makes it self-contained by copying in the resources that the application uses (like libraries, graphics, and plugins) into a bundle. The resulting bundle can be distributed as an AppDir or as an AppImage to users, or can be put into cross-distribution packages. It can be used as part of the build process to deploy applications written in C, C++, and other compiled languages with systems like CMake, qmake, and make. When used on Qt-based applications, it can bundle a specific minimal subset of Qt required to run the application. This tool is conceptually based on the Mac Deployment Tool, macdeployqt in the tools applications of the Qt Toolkit, but has been changed to a slightly different logic. -

TinyGSM
A small Arduino library for GSM modules, that just works
A small Arduino library for GSM modules that just works. This library is easy to integrate with lots of sketches that use Ethernet or WiFi. PubSubClient (MQTT), Blynk, HTTP Client, and File Download examples are provided. Arduino GSM library uses 15868 bytes (49%) of Flash and 1113 bytes (54%) of RAM in a similar scenario. TinyGSM also pulls data gently from the modem (whenever possible), so it can operate on very little RAM. Now, you have more space for your experiments. TCP (HTTP, MQTT, Blynk, ...) All modules support TCP connections. Most modules support multiple simultaneous connections. TCP and SSL connections can usually be mixed up to the total number of possible connections. Many GSM modems, WiFi, and radio modules can be controlled by sending AT commands over Serial. TinyGSM knows which commands to send, and how to handle AT responses, and wraps that into the standard Arduino Client interface. -

Brynet
A Header-Only cross-platform C++ TCP network library
Header Only Cross-platform high-performance TCP network library using C++ 11. The server uses two network threads and one logic thread, the client uses one network (also process logic) thread. Every packet size is 46 bytes. Every packet contains the client's id. Server broadcast packets to all clients when recv one packet from any client. The client sends one packet when recv packet from the server and the packet's id is equal self. -

proxysocket
Portable C library for proxy client support using standard SOCKETs.
Cross-platform C library to establish TCP connections using a proxy. Supports different connection methods: - no proxy (optionally allowing to bind to a local address and/or port) - HTTP proxy: only CONNECT method, only without authentication or basic authentication - SOCKS4: without IDENT functionality - SOCKS5 (RFC 1928): only without authentication or username/password Features: - Currently only support IPv4 TCP connections. - Returns a standard operating system SOCKET that can be manipulated by standard operating system functions like send() and recv(). - Supports daisy-chaining multiple proxies. - Can also be used for direct connections (without proxy) optionally binding to a local address and/or port. -

CSS Preprocessor
CSS validation and advanced preprocessor with nesting and variables
CSS Preprocessor is a parser, compiler, and assembler which extends the CSS language to allow nested rules and attributes, variables / @mixin, functions, and especially, strong validation of your source code so you know that it will work the first time you use it in your browser. The library is written in C++ allowing any other C++ project to work with CSS without having to rewrite their own parser. The library supports 4 output levels from ultra compressed CSS code to beautified CSS code. The preprocessor features are based on other existing CSS processors such as SASS and {less}, although the syntax is mainly based on the SASS syntax (i.e. variables use the $ character as their introducer). See the Wiki and csspp documentation for additional information. -

EGNLA
Heterogeneous cluster for acceleration of linear algebra computations
This project deals with a new concept of the heterogeneous grid for acceleration of the numerical linear algebra computing. We design this grid with respect to maximal ratio between cost and computational power. It allows a parallelization of scientific codes with minimal programming effort. We also optimize grid concept to be less sensitive to network parameters. -

libqtcp
Library that provides communication over a network
The project is based on Qt framework. It wraps the capabilities related to networking in simple to use, service based server and client configurations. The library starts with the tcp protocol as it is implemented in the QtNetwork module[1] and creates two top level managing structures: a client and a server. Both support multiple connections that may or may not be encrypted. On top of this basic framework we implement the service support. Any server may host any number of services that are identified by their names in the client-server connection. The source contains simple igu8i based implementations for both a client and a server.

The library recognizes all TLDs, whatever the number of levels the TLD includes (i.e. .com has one, .au has up to 4 such as .schools.nsw.edu.au) this library will be capable of extracting it. The library is for C, C++, and PHP. -
