FRRouting (FRR) is a free and open-source Internet routing protocol suite for Linux and Unix platforms. It implements BGP, OSPF, RIP, IS-IS, PIM, LDP, BFD, Babel, PBR, OpenFabric and VRRP, with alpha support for EIGRP and NHRP. FRR’s seamless integration with native Linux/Unix IP networking stacks makes it a general-purpose routing stack applicable to a wide variety of use cases including connecting hosts/VMs/containers to the network, advertising network services, LAN switching and routing Internet access routers, and Internet peering. FRR has its roots in the Quagga project. In fact, it was started by many long-time Quagga developers who combined their efforts to improve on Quagga’s well-established foundation in order to create the best routing protocol stack available. We invite you to participate in the FRRouting community and help shape the future of networking.

QMK (Quantum Mechanical Keyboard) is an open source community centered around developing computer input devices. The community encompasses all sorts of input devices, such as keyboards, mice, and MIDI devices. This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line. Keyboards powered by QMK are Planck, Preonic, ErgoDox EZ, Clueboard, Cluepad, Gergo, Georgi, and Atreus. QMK is compatible with lots of other community-supported keyboards and projects. QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu.

Atlas is a MySQL protocol-based database middleware project developed and maintained by the infrastructure team of the Web platform Department in QIHU 360 SOFTWARE CO. LIMITED(NYSE:QIHU). It fixed lots of bugs and added lot of new functions on the basis of MySQL-Proxy 0.8.2. Currently, the project has been widely applied in QIHU, many MySQL businesses has connected to the Atlas platform. The number of read and write requests forwarded by Atlas has reached billions. Rewrite all lua code with C, Lua is only used for the management interface. Rewrite the network model and the threading model. Optimize the locking mechanism, performance improved immensely. When Atlas start, it will create multiple threads. One of them is the main thread, the others are working threads. The main thread is responsible for monitoring the connecting requests from clients, and the working thread only monitor the command request from the main thread.
