Cromfs is a compressed read-only filesystem for Linux. Cromfs is best at archiving gigabytes of big files that have a lot of redundancy. It aims primarily at achieving a strong compression, even at the cost of memory and CPU time resources. It uses the LZMA compression algorithm from 7-zip and BLOCK merging.

生成Trick文件工具 1.Open command line 2.input tricktest Usage: TrickTest -f -o -i -f source mpeg2 file to trick -o trick output directory -i output file id -m max coding error, default 0 -b max bitrate for trick generate, default 0 mean no limit -s trick buffer BLOCK size, must be n*188 -l log file, default c:\tricktest.log example: tricktest -f 黑鷹行動.mpg -o c:\temp -i A -m 1000 -b 3750000 soure file: 黑鷹行動.mpg output directory: c:\temp filename: 000000A,000000A.ff,000000A.fr,000000A.vvx max coding error: 1000 trick generation speed: 3750000 bps a

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 線程 靜態鎖，對象鎖， synchronized 是鎖方法還是鎖對象？還是鎖類？如何實現？？ 部分代碼如下， public static Object lock=new Object() //靜態鎖，鎖類，不是鎖對象了！！所以兩個線程同時 運行兩個 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) } } }

Among the many features built into Microchip’sEnhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations.Devices like the PIC18F452 are designed with a designated“boot BLOCK”, a small section of protectable program memory allocated specifically for bootload firmware.
