cheese 是一款用你的摄像头拍照片和视频的软件，并带一些有趣的特殊效果，让你同别人分享快乐的软件。cheese最初是作为Google’s 2007 Summer of Code一部分，主要由 daniel g. siegel和 Rapha?l Slinckx主持的，经过几个月的发展，cheese已经有大部分经典大头贴的功能。在后台，cheese是利用GStreamer来实现照片和视频的各种效果的。 　　cheese主页http://www.gnome.org/projects/cheese/- Take photos and videos with your webcam, with fun graphical effects Cheese currently requires: - glib-2.0 >= 2.16.0 - gobject-2.0 >= 2.12.0 - gio-2.0 >= 2.16.0 - gtk+-2.0 >= 2.17.4 - gdk-2.0 >= 2.14.0 - gnome-desktop-2.0 >= 2.26.0 - gconf-2.0 >= 2.16.0 - gstreamer-0.10 >= 0.10.20 - gstreamer-plugins-base-0.10 >= 0.10.20 - gstreamer-plugins-good-0.10 >= 0.10.8 - gnome-vfs-2.0 - dbus-1 - dbus-glib-1 - hal - cairo - pango - librsvg >= 2.18.0 - libebook-1.2 (evolution-data-server) - postr for Flickr export (optional) - f-spot for F-Spot export (optional) - nautilus-sendto for better export mechanism (optional) - a webcam - a bra

LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client. The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents. -LibTorrent is a BitTorrent library writte n in C for* nix. with a focus on high performance and good code.

Linux 是一个源码开放的操作系统，无论是普通用户还是企业用户都可以编写自己的内核代码，再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的，这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。 一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要，因为内核的局限性太大，如不能在终端上打印，不能做大延时的处理等等。当我们需要做这些的时候，就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样，内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍，也没有其他文章对此进行总结，所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。-Linux is an open-source operating system, both ordinary users or enterprises, users can prepare their core code, coupled with the standard kernel cutting thereby making up their own operating system. There are a lot of low-end users of the network equipment from the standard operating system Linux is improving from the This also shows that the more and more people are added to the Linux kernel development groups. One or more modules and the realization of general Linux can not satisfy the needs of system software, because the core is too restrictive, such as the terminal can print, can not handle the bigger Delay etc..
