Amarok是一款在LINUX或其他类UNIX操作系统中运行的音频播放器软件。 经过两年开发后,Amarok 项目团队宣布 Amarok 的 2.0 版本正式发布。得益于 KDE 4 的跨平台特性,Amarok 2.0 除了可在 Linux 系统上运行之外,也能够在其他系统上使用,包括 Windows 和 Mac OS X。Amarok 2.0 相比 Amarok 1.x 而言,它是一个革新的版本。Amarok 2.0 对用户界面(UI)进行了完全的重新设计,集成了 Magnatune、Jamendo、MP3tunes、Last.fm、Shoutcast 等在线服务,对脚本 API 和插件支持进行了修订,从 KDE 3 迁移到了 KDE 4 框架,以及使用了 Solid、Phonon、Plasma 等核心技术。 Amarok 开发者说,发布 Amarok 2.0 仅仅只是一个开始,他们将继续增强和改进 Amarok 的功能。

A "code-what"? Unless you have spent some time working in the area of reverse engineering, chances are you have not heard of the term "codecave" before. If you have heard of it, you might not have read a clear definition of it or quite understand what it is or why it is useful. I have even asked seasoned assembly programmers about the term before and most of them had not heard of it. If it is new to you, do not worry, you are not the only one. It is a term that is scarcely used and is only useful in a reverse engineering context. Furthermore, is it "codecave" or "code cave"? I am not quite sure, but I will try my best to refer to it consistently as a "codecave". A space may sneak in there from time to time

Instead of finding the longest common subsequence, let us try to determine the length of the LCS. Then tracking back to find the LCS. Consider a1a2…am and b1b2…bn. Case 1: am=bn. The LCS must contain am, we have to find the LCS of a1a2…am-1 and b1b2…bn-1. Case 2: am≠bn. Wehave to find the LCS of a1a2…am-1 and b1b2…bn, and a1a2…am and b b b b1b2…bn-1 Let A = a1 a2 … am and B = b1 b2 … bn Let Li j denote the length of the longest i,g g common subsequence of a1 a2 … ai and b1 b2 … bj. Li,j = Li-1,j-1 + 1 if ai=bj max{ L L } a≠b i-1,j, i,j-1 if ai≠j L0,0 = L0,j = Li,0 = 0 for 1≤i≤m, 1≤j≤n.
