原创 算法 —— 冒泡排序
冒泡排序冒泡排序是比较两个相邻元素，如果它们不符合预期的顺序就交换的一个排序过程。冒泡排序就像水中气泡上升到水面的运动一样，数组的每个元素在每次迭代中都把当前迭中最大(或最小)的元素移动到最后，因此被称为冒泡排序。冒泡排序的工作流程1.第一次迭代（比较和交换）2.后续的迭代过程代码实现Swift实现import Foundationfunc bubbleSort(array:inout Array<Int>) { //遍历数组的每个元素,让每个元素都走一遍冒

原创 异或的两个常见应用
异或的两个常见应用异或运算符"∧"也称XOR运算符。它的规则是：若参加运算的两个二进位同号，则结果为0（假）；异号则为1（真）。即 0∧0＝0，0∧1＝1， 1^0=1，1∧1＝0。运算说明0 ^ 0=0,0 ^ 1=10异或任何数，其结果=任何数1 ^ 0=1,1 ^ 1=01异或任何数，其结果=任何数取反x ^ x=0任何数异或自己，等于把自己置0翻转特定位比如： 01111010，想使其低4位翻转，即1变为0，0变为1。将它与 000

ChessWZQ1.0 采用C/S模式编写
客户端和服务器端的交互有class Message中定义，有很好的可扩展性（见 Message 定义）
客户端负责界面维护和收集用户输入的信息，及错误处理
服务器维护各在线用户的基本信息和任意两个对战用户的棋盘信息，动态维护用户列表
鉴于Applet的下载速度太慢，故做成Application
用法:
/class/
1.先运行server.bat
2.再运行client.bat (里面的用户名可以修改,serverAddress也可以,不过我是按localhost调的)
3.可同时启动多个Client

zlevoclient-0.8-bin_i386.tar.gz
ZLEVOClient v0.2 Readme
编译：
编译需要libpcap库，一般Linux发行版里面安装libpcap-dev包即可，如ubuntu： sudo apt-get install libpcap-dev
然后从命令行进入源代码目录，运行make，应该很快就能生成zdclient，当然前提是系统中安装了gcc等编译环境，这里不再累赘。
理论上兼容包括Mac、Solaris等Unix系系统。
运行：
运行需要root权限，看例子即可：
sudo ./zlevoclient -u xs_12_410_6 -p 123456 --background
u、p分别是用户名、密码，--background参数可让程序进入后台运行，具体可./zdclient --help查看
压缩包内提供了启动脚本zlevo_run.sh，用gedit等编辑软件修改sh文件内的username、password，
以后运行sudo ./zlevo_run.sh即可。
终止：
默认方式启动的程序，按Ctrl + C即可正常下线，程序终止；
如果是以后台方式启动的，可另外使用-l参数运行zlevoclient，当然也需要root权限，便能通知原程序下线并退出了。

UtraEdit语法加亮脚本全集（400多种语言）
To add one of these wordfiles to your syntax highlighting
Version 15.00 and later: To add one of these wordfiles, all you need to do is download and save it into your "wordfile" directory which by default is %appdata%\IDMComp\UltraEdit\wordfiles, unless you have specified a different directory. Further help and documentation is available here.
Version 14.20 and previous: To add one of these wordfiles, please visit this power tip for instructions.
How to enable automatic highlighting with the new wordfile
Please visit our adding or removing file extensions for default syntax highlighting power tip for documentation on enabling automatic highlighting for the new wordfile.
UltraEdit's help file includes help on modifying the wordfile if it is needed under "Syntax Highlighting."
Help for users writing their own wordfiles
One of our forum power users, Mofi, has written a series of open-source macros designed to help users alphabetically sort and test the validity of new wordfiles. This is a very valuable resource for users who need a wordfile that has not yet been written, and use of these macros can make writing your own wordfile much easier.

- Include win64 native binary in the release.
- Fixed failures on big endian hosts.
- BIOS: Support for up to 2M ROM BIOS images.
- GUI: select mouse capture toggle method in .bochsrc.
- Ported most of Qemu's 'virtual VFAT' block driver
(except runtime write support, but plus FAT32 suppport)
- Added write protect option for floppy drives.
- Bugfixes / improved internal debugger + instrumentation.
Detailed change log :
- CPU and internal debugger
- Implemented Process Context ID (PCID) feature
- Implemented FS/GS BASE access instructions support
(according to document from http://software.intel.com/en-us/avx/)
- Rewritten from scratch SMC detection algorithm
- Implemented fine-grained SMC detection (on 128 byte granularity)
- Bugfixes for CPU emulation correctness and stability
- Fixed failures on Big Endian hosts !
- Print detailed page walk information and attributes in
internal debugger 'page' command

- Bochs now can be compiled as native Windows x86-64 application
(tested with Mingw gcc 4.5.1 and Microsoft Visual Studio Express 2010)
- Added ability to configure CPUID stepping through .bochsrc.
The default stepping value is 3.
- Added ability to disable MONITOR/MWAIT support through .bochsrc
CPUID option. The option is available only if compiled with
--enable-monitor-mwait configure option.
- Determine and select max physical address size automatically at
configure time:
- 32-bit physical address for 386/486 guests
- 36-bit physical address for PSE-36 enabled Pentium guest
- 40-bit physical address for PAE enabled P6 or later guests
- Update config.guess/config.sub scripts to May 2010 revisions.

- USB
- converted common USB code plus devices to the new 'usb_common' plugin
Now the USB device classes no longer exist twice if both HC plugins are loaded.
- added 'pseudo device' in common USB code for the device creation. This makes
the HCs independent from the device specific code.
- USB MSD: added support for disk image modes (like ATA disks)
- USB printer: output file creation failure now causes a disconnect
- re-implemented "options" parameter for additional options of connected
devices (currently only used to set the speed reported by device and to

- VMX, 1G pages in long mode, MOVBE instruction
- Bugfixes for CPU emulation correctness, debugger and CPU instrumentation.
- New config interface 'win32config' with start and runtime menu
- USB: added OHCI support, external hub and cdrom
- Added user plugin interface support.
Detailed change log :
- CPU and internal debugger
- Support for VMX hardware emulation in Bochs CPU, to enable configure with
--enable-vmx option
Nearly complete VMX implementation, with few exceptions:
- Dual-monitor treatment of SMIs and SMM not implemented yet
- NMI virtualization, APIC virtualization not implemented yet
- VMENTER to not-active state not supported yet
- No advanced features like Extended Page Tables or VPID
- Support for configurable MSR registers emulation, to enable configure with
--enable-configurable-msrs option
Look for configuration example in .bochsrc and msrs.def
- Support new Intel Atom(R) MOVBE instruction, to enable configure with
--enable-movbe option
- Support for 1G pages in long mode, to enable configure with
--enable-1g-pages option
- Support for > 32 bit physical address space in CPU. Up to 36 bit could be
seen in legacy mode (PAE) and up to 40 bit in x86-64 mode.
Still support the same amount of the physical memory in the memory object,
so system with > 4Gb of RAM yet cannot be emulated.
To enable configure with --enable-long-phy-address option.
- Implemented modern BIOSes mode limiting max reported CPUID function
to 3 using .bochsrc CPU option. The mode is required in order to
correctly install and boot WinNT.
- Added ability to configure CPUID vendor/brand strings through .bochsrc
(patch from @SF by Doug Reed).
- Many bugfixes for CPU emulation correctness (both x86 and x86-64).
- Updated CPU instrumentation callbacks.
- Fixed Bochs internal debugger breakpoints/watchpoints handling.
- Configure and compile
- Added ability to choose Bochs log file name and Bochs debugger log file
name from Bochs command line (using new -log and -dbglog options)
- Removed Peter Tattam's closed source external debugger interface from
the code.
- Removed --enable-guest2host-tlb configure option. The option is always
enabled for any Bochs configuration.
- Removed --enable-icache configure option. The option is always enabled
for any Bochs configuration. Trace cache support still remains optional
and could be configured off.
- Added configure option to compile in GUI frontend for Bochs debugger,
to enable configure with --enable-debugger-gui option.
The GUI debugger frontend is enabled by default with Bochs debugger.
- Removed --enable-port-e9-hack configure option. The feature now could be
configured at runtime through .bochsrc.
- Added configure option to enable/disable A20 pin support. Disabling the
A20 pin support slightly speeds up the emulation.
- reduced dependencies between source files for faster code generation
- BIOS
- Added S3 (suspend to RAM) ACPI state to BIOS (patch by Gleb Natapov)
- Implemented MTRR support in the bios (patches by Avi Kivity and Alex
Williamsion with additions by Sebastian Herbszt)
- Bug fixes
- I/O Devices
- Added user plugin support
- remaining devices converted to plugins: pit, ioapic, iodebug

- Config interface
- new config interface 'win32config' with start and runtime menu is now
the default on Windows ('textconfig' is still available)
- win32 device config dialogs are now created dynamicly from a parameter list
(works like the wx ParamDialog)
- changes in textcofig and the wx ParamDialog for compatibility with the new
win32 dialog behaviour
- Bochs param tree index keys are case independent now
- some other additions / bugfixes in the simulator interface code

Changes in 2.3.6 (December 24, 2007):
Brief summary :
+ More than 25% emulation speedup vs Bochs 2.3.5 release!
- Thanks to Darek Mihocka (http://www.emulators.com)
for providing patches and ideas that made the
speedup possible!
+ Up to 40% speedup vs Bochs 2.3.5 release with trace cache optimization!
- Lots of bugfixes in CPU emulation
- Bochs benchmarking support
- Added emulation of Intel SSE4.2 instruction set
Detailed change log :
- CPU
- Added emulation of SSE4.2 instruction set, to enable use
--enable-sse=4 --enable-sse-extension configure options
to enable POPCNT instruction only use configure option
--enable-popcnt
- Implemented MTRR emulation, to enable use --enable-mtrr configure
option. MTRRs is enabled by default when cpu-level >= 6.
- Implemented experimental MONITOR/MWAIT support including optimized
MWAIT CPU state and hardware monitoring of physical address range,
to enable use --enable-monitor-mwait configure option.
- Removed hostasm optimizations, after Bochs rebenchmarking it was found
that the feature bringing no speedup or even sometimes slows down
emulation!
- Merged trace cache optimization patch, the trace cache optimization
is enabled by default when configure with --enable-all-optimizations
option, to disable trace cache optimization configure with
--disable-trace-cache
- Many minor bugfixes in CPU emulation (both ia32 and x86-64)
- Updated CPU instrumentation callbacks
- Bochs Internal Debugger and Disassembler
- Many fixes in Bochs internal debugger and disassembler, some debugger
interfaces significantly changed due transition to the param tree
architecture
- Added support for restoring of the CPU state from external file
directly from Bochs debugger
- Configure and compile
- Renamed configure option --enable-4meg-pages to --enable-large-pages.
The option enables page size extensions (PSE) which refers to 2M pages
as well.
- Removed --enable-save-restore configure option, save/restore feature
changed to be one of the basic Bochs features and compiled by default
for all configurations.
- Added new Bochs benchmark mode. To run Bochs in benchmark mode execute
it with new command line option 'bochs -benchmark time'. The emulation
will be automatically stopped after 'time' millions of emulation
cycles executed.
- Another very useful option for benchmarking of Bochs could be enabled
using new 'print_timestamps' directive from .bochsrc:
print_timestamps: enable=1
- Added --enable-show-ips option to all configuration scripts used to
build release binaries, so all future releases will enjoy IPS display.
- Enable alignment check in the CPU and #AC exception by default for
--cpu-level >= 4 (like in real hardware)
- SF patches applied

由于c++刚学完函数一章，而练习需要用pow()这个函数，于是就特发奇想，想自己能否写一个能实现pow()功能的函数，经过一段努力，算有了一些结果。
众所周知，pow(double t,double m)是c++提供计算x的y次幂的函数，虽然系统提供了这个pow(),但我还是想自己写一个自己的pow()。不过要写出这个pow可能不太容易，因为指数m要求是double的，即可以是小数，那就不是简单的循环可以做出的。
