We’ve been surprised that our very expensive Samsung SSD’s buyed some years ago for more CHF 800-1000 per 256GB of size (1+2) is not as fast as any other traditional Harddisk. Compared to actual newer ones from Samsung 470 series, I’m sure we were the ones that buyed for the technology research department of Samsung by buying the SSD’s for many bucks during their development.
By taking a look onto the newest model’s performance, it could be that the research was successful and the SSD’s we buy now are really performant ones.

On Windows, you can right click on your Desktop to select New->Shortcut. On Linux, it isn’t as easy like this.
To be faster, I recommend to open a shell without root privileges. As an example, we’re goint to create a Desktop File that opens a Remote Desktop Session to “server2” using the “rdesktop” executable. To do so, we create a file, set it as executable and open it in gedit with the following commands:
- cd /home/username/Desktop
- touch server2.desktop
- chmod +x server2.desktop
A new Windows appears, where we now can insert the following text template:
Exec=rdesktop -g 1280×900 servername
Comment=Start Remote Desktop Session
Save the file and check out the new Icon on your Desktop. The Icon file defined in Line 4 can be created by searching for any Icon on Google Images and covert it using the following online Tool:

These are just some notes on commands and hints I’ve found using Google during my Linux installation and daily tasks. Some of them are related to my Linux Mint Distribution, but should also work on others.
aptitude resp. apt-get
To search for a software bundle:
$> apt-cache search
To install a software bundle from the search above:
$> apt-get install
Install downloaded .deb or .pkg files
$> sudo dpkg -i software.deb
$> sudo aptitude install software.deb
$> sudo rpm -i software.rpm
A lot of drivers are only available as i386 (32-bit) Installation Packages. If you have luck, the Vendors made a Linux driver for their Device, but normally this is not the case. If you find one, the next problem could be that it is a 32-bit driver, that can only be used on 32-bit systems (I wasn’t able to install a 32-bit one on my 64-bit system).

-> add the “discard” option to a filesystem to enable SSD Trim function
-> use “sudo blkid” to get a filesystem’s UUID

Since Christmas 2011 I’m trining to work on Linux Mint at home. It was clear that it isn’t possible living without any Windows Operation system installed, so I’ve decided to use Windows 7 in a virtual Machine. In VMware Workstation there’s a very useful feature called “Unity”, that makes all Windows Applications seamless available in the host operation system. That’s what I need to have the best feeling in the daily business.
After installing VMware Workstation, the first start already stopped with a error message, that I had to search in /tmp/vmware-root/setup-xxxx.log. At the end of the Logfile was a message like “Failed to compile module vmmon!”.
Google told me this is a known error under different Kernel Versions. In my case, I’m using this version:
# uname -a
Linux laptop7 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
In VMware’s communities was a post explaining how to Patch my problem:
Here’s how to in quick steps:
After this steps, the VMware modules can be compiled into the Kernel using the following command or by starting VMware Workstation again.
- vmware-modconfig –console –install-all
