SOME BACKGROUND ON DESIGN PATTERNS The term “design patterns” sounds a bit formal to the uninitiated and can be somewhat off-putting when you first encounter it. But, in fact, design patterns are just convenient ways of reusing object-oriented code between projects and between programmers. The idea behind design patterns is simple-- write down and catalog common interactions between objects that programmers have frequently found useful.

學會一個程式語言，是一回事兒；學會如何以此語言設計並實作出有效的程式，又是一回事兒。C++ 尤其如此，因為它很不尋常地涵蓋了罕見的威力和豐富的表現力，不但建立在一個全功能的傳統語言（C）之上，更提供極為廣泛的物件導向（object-oriented）性質，以及對templates 和exceptions（異常狀態）的支援。

A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.

java 线程 静态锁，对象锁， synchronized 是锁方法还是锁对象？还是锁类？如何实现？？ 部分代码如下， public static Object lock=new Object() //静态锁，锁类，不是锁对象了！！所以两个线程同时 运行两个 TestThread 的execute（ ），也可以同步！！！ public void execute(){ // synchronized(lock){ for(int i=0 i<20 i++){ try { Thread.sleep(30) } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace() } System.out.println(Thread.currentThread().getName()+Thread.currentThread ().getName()+" "+i) } } }

Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and direc- tional fi lter banks. The contourlet expansion is composed of basis images oriented at various directions in multiple scales, with fl exible aspect ratios. Given this rich set of basis images, the contourlet transform effectively captures smooth contours that are the dominant feature in natural images.
