Amarok是一款在LINUX或其他類UNIX操作系統中運行的音頻播放器軟件。 經過兩年開發后,Amarok 項目團隊宣布 Amarok 的 2.0 版本正式發布。得益于 KDE 4 的跨平臺特性,Amarok 2.0 除了可在 Linux 系統上運行之外,也能夠在其他系統上使用,包括 Windows 和 Mac OS X。Amarok 2.0 相比 Amarok 1.x 而言,它是一個革新的版本。Amarok 2.0 對用戶界面(UI)進行了完全的重新設計,集成了 Magnatune、Jamendo、MP3tunes、Last.fm、Shoutcast 等在線服務,對腳本 API 和插件支持進行了修訂,從 KDE 3 遷移到了 KDE 4 框架,以及使用了 Solid、Phonon、Plasma 等核心技術。 Amarok 開發者說,發布 Amarok 2.0 僅僅只是一個開始,他們將繼續增強和改進 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.
