"This script will show a git diff in vimdiff format. -g will use gvimdiff instead of vimdiff."

"A full-featured and high-performance (see benchmark) event loop that is loosely modelled after libevent, but without its limitations and bugs. It is used, among others, in the GNU Virtual Private Ethernet and rxvt-unicode packages, and in the Deliantra MORPG Server and Client. Features include child/pid watchers, periodic timers based on wallclock (absolute) time (in addition to timers using relative timeouts), as well as epoll/kqueue/event ports/inotify (for file watchers) support, fast timer management, time jump detection and correction, and ease-of-use. It can be used as a libevent replacement using its emulation API or directly embedded into your programs without the need for complex configuration support. A full-featured and well-documented perl interface is also available."

"This project uses a language-based technique to unify two seemingly opposite programming models for building massively concurrent network services: the event-driven model and the multithreaded model. The result is a unified concurrency model providing both thread abstractions and event abstractions. We implemented the unified concurrency model in Haskell, a pure, lazy, functional programming language. Our implementation demonstrates how to use these techniques by building an application-level thread library with support for multiprocessing and asynchronous I/O mechanisms in Linux. The thread library is type-safe, is relatively simple to implement, and has good performance. Application-level threads are extremely lightweight (scaling to 10,000,000 threads!) and our scheduler, which is implemented as a modular and extensible event-driven system, outperforms NPTL in I/O benchmarks."
