Where is the Internet Explorer cache folder in Windows Vista and above?

For those who use English version of Windows and occasionally work with files containing non-Unicode characters (e.g. Chinese characters) will find it difficult and frustrate.

I memorized 8 useful grep command option switches that are useful in most cases.

You know that uname -a only prints the Linux kernel version as well as CPU architecture (e.g. 32/64bit), it doesn’t tell you the Linux distribution name and its release number.

Imagine that tape drive is not available and the local disk space is not enough for creating a full database backup. Can you mount a shared folder and create database backup to this network resource?

It won’t take you more than 3 minutes (perhaps even less than 1 minute) to configure Linux Samba to host a shared folder on Linux system.

It’s not easy and intuitive for most people who use rpm to install or upgrade a RHEL package that has a hell of a lot of dependencies to resolve. The yum, another RPM package manager, is definitely a life-saver for RHEL sysadmin!
