Linux Process Viewer with Thread Support
When optimizing Turnkey ZurmoCRM within VirtualBox, I want to know how it handle session by thread and physical multi-core processor. I am also interested how hyper-threading works, too. Therefore, I need a replacement for top and the buil-in monitor in QTS.
I choose htop.
Check your RAM usage with free in Linux
free show RAM usage information. It helps you to know how much RAM is used by system, buffers, and cache. But it is a little bit complex for first time user, especially line 2. I am going to explain line by line and with some example.

Some Linux commands are useful but I didn’t use it very often. Here I prepare a list to look up faster. It will be maintained and updated here.

Download and Verify OpenSuSE 13.1 Image with Hash
It’s good to see OpenSuSE 13.1 is available for download on 2013/11/19. But it is difficult to download from Direct Link, too crowded. I select Pick Mirror, and it will list several mirror site for you. Choose the closest may speed up your download.
Please verified your download before you use it. Make sure it is the same as the original copy. I use SHA-256 and MD5 to double confirm. A good hash function should generate no collisions on different source. On the other hand, if it is the same content, the hash should be exactly the same.
