如果你是某类人，干活儿就很难离开Windows command line，这时候Console2可能就适合你。 和Linux下有强大的Konsole和gnome terminal不同，Windows里的命令行工具基本只有自带的cmd.exe可选，那个简陋程度大家都清楚。 Console2是cmd.exe的前端，和Konsole，Gnome Ternimal之于bash的角色是一样的。Console2支持多tab，这是最大亮点，因此一个窗口里可以用多个tab完成不同任务，方便又不会往任务栏和桌面上添加太多窗口，另外也支持其他terminal程序比如cygwin带的bash，锦上添花的功能有支持透明背景，可配置的buffer，可配置的字体和颜色，热键等。 完全绿色，解压就能用。在Vista下还有点问题，不过XP已经验证过，挺好。 Tags: console, shell, terminal

传统的文件系统：一个目录下随着文件个数的增加，访问速度会下降。
100个文件/节点每秒可以完成6000次定位；
500个文件时候已经下降到3000次 速度为100个文件的一半；
5000个文件时候速度会下降一个数量级；

XFS在设计种大量使用了B-Tree: 包括在文件节点的结构上；因此XFS上文件个数到万级，文件的定位速度仍然下降不多。

MONDAY! We started the week off by having a little MLK, JR. weekend sale on our web site.
