Process Explorer v11.13
By Mark Russinovich
Introduction
Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.
The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.
The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
Process Explorer works on Windows 9x/Me, Windows NT 4.0, Windows 2000, Windows XP, Server 2003, and 64-bit versions of Windows for x64 and IA64 processors, and Windows Vista.

Customize Vista Favorite Links

Customize Vista Favorite Links
I was stuck with this for months (really!) :
Favorite Links in Vista's Windows Explorer is a really nice feature (although not my best one *)... but why the *** they did not put "Downloads" and "Videos" on my favorite links ?? I go there 60 times a day.
So how do you customize favorite links ?
.... this was so easy... just go to C:\Users\YourUsername\Links and add folder shortcuts ! (or virtual folders, but app shortcuts are not supported).
实数集

18世纪，微积分学在实数的基础上发展起来。但当时的实数集并没有精确的定义。直到1871年，德国数学家康托尔第一次提出了实数的严格定义。定义是由四组公理为基础的：
1、加法公理：
1.1对于任意属于集合R的元素a、b，可以定义它们的加法a+b，且a+b属于R；
1.2加法有恒元0，且a+0=0+a=a（从而存在相反数）；
1.3加法有交换律，a+b=b+a；
1.4加法有结合律，(a+b)+c=a+(b+c)。
2、乘法公理：
2.1对于任意属于集合R的元素a、b，可以定义它们的乘法a·b，且a·b属于R；
2.2乘法有恒元1，且a·1=1·a=a（从而除0外存在倒数）；
2.3乘法有交换律，a·b=b·a；
2.4乘法有结合律，(a·b)·c=a·(b·c)；
2.5乘法对加法有分配率，即a·(b+c)=(b+c)·a=a·b+a·c。
3、序公理：
3.1任何x、y属于R，x<y、x=y、x>y中有且只有一个成立；
3.2若x<y，对任意z属于R，都有x+z<y+z；
3.3若x<y，z>0，则x·z<y·z；
3.4传递性：若x<y，y<z，则x<z。
4、完备公理：
有两种常见说法，是等价的：
(1)任何一个非空有上界的集合（包含于R）必有上确界。
(2)设A、B是两个包含于R的集合，且对任何x属于A，y属于B，都有x<y，那么必存在c属于R，使得对任何x属于A，y属于B，都有x<c<y。
符合以上四组公理的任何一个集合都叫做实数集，实数集的元素称为实数。
