Did you have trouble when connecting your Linux to your network?  Did the network speed drop? Before you throw your computer, please check its log with dmesg. If dmesg shows repeated messages like eth0: link up and/or eth0: link down, then it must be your lan card driver problem. If you use Realtek LAN Card R8168, then it is the problem. Your Linux will load r8169 driver that have some bugs, instead of r8168. So, the solution of this problem is installing r8168 driver to your Linux, and disable r8169 module.

In Windows, you can set your wallpaper as a slideshow. So if you have many pictures and want to make all of them your wallpaper, you can do it with slideshow wallpaper. One of my friend said that Ubuntu already has it by default. But when i use Linux Mint, i can’t find it in wallpaper selection menu. So i search for how to use slideshow wallpaper in Linux Mint.

And then i found Desktop Drapes. It is a gnome-based application that can make auto-change wallpaper based on your pictures collection. Overall, it is a good application. But minimum interval for 1 wallpaper is only 5 minutes. In Windows you can have about 30 seconds interval.

To use it, you can install it from repositories with this command :

apt-get install drapes

Below is example screenshots of Drapes running in my computer.

But there is another step that have to be done to disable a modules from autoloading at boot time. Read the rest of this entry »

User Mode Linux (UML) is my favourite tool for simulating real network environtment. Because it’s simple and using small computer resources. But you can simulate a full working server in a UML. In this post, i will show you how to prepare a host computer for running User Mode Linux. Unlike Qemu, there is a ‘special treatment’ for the host so it can run UMLs. Read the rest of this entry »

Nowadays, RAM size is getting bigger than before. In 2004, i have desktop computer with 1 GB RAM. At that time, i think it’s more than enough. But today, computer with RAM size more than 2 GB is common. Few months ago, i upgraded my notebook’s RAM to 4 GB. But with 32-bit OS, only 3 GB that can be read. If you use Windows 32-bit version, dxdiag can read the actual memory size, but Task Manager only read maximum 3 GB. If you use Windows and have RAM more than 3 GB, you must install the 64-bit version. Read the rest of this entry »
