My New Pet

Recently me and my dear Maggi just released all of our adult Cichlid fishes to a big pond in our school, since they are getting larger and larger and too crowded to fit in our fish tank. So we released them and they seem to be happy to swim in a large pond. When we released them, they swam so fast back and forward and swam around the pond like kids in an amusement park!

Couple days later, we went to our custom 北高雄 aquarium store on 明誠路 and tried to find some new fishes to fill our empty fish tank. We were attracted by a kind of fish that has colorful and unique body shape, as well myriad pattern on each of the kind. That special fish is called Discus, in Chinese it's called 七彩神仙! Discus has flat and round body shape and attractive color like metallic blue, red, orange, white, etc.

So..., we did some research online of where the places that we can go to see and buy Discus. We went to at least 14 stores before we finally decide to buy discus. I will post and give comments about the Aquarium stores that we have visited in the next article. Here are some of the pictures of my new fishes...

The tail shrinks, seems like it has not adapt to the new environment yet

They are so shy and afraid to face people, also may be haven't adapted yet

They only show their ass to me whole night long!

What a rare moment that they swim sideward to me

Standing on the corners

Ubuntu Remote Desktop

# Let's say you have installed xrdp (in Terminal: sudo apt-get install xrdp) and you have used RDP remote desktop quite a while to connect Windows to Ubuntu or one Ubuntu to another Ubuntu, then you might bump to a problem when you want to install or do some system settings. For example when you want to use synaptic package manager to install something. You will get an error or warning like:

"Failed to run /usr/sbin/synaptic as user root
Unable to copy the users Xauthorization file."

To solve this problem, firstly connect to your Ubuntu using the Remote Desktop Connection (in Windows: Start -> Run -> mstsc (Enter) in order to access the Remote Desktop Application; in Ubuntu: Applications -> Internet -> Terminal Server Client). After you have logged into your Ubuntu, then bring up your Terminal (Ctrl+Alt+T) and type the following instructions:
cd ~
touch ~/.Xauthority
chmod 600 ~/.Xauthority

# When you use one Ubuntu to "remote desktop" to another Ubuntu, there's something that might bother you. In Ubuntu's remote desktop application, there's no auto hide button or menu like Windows Remote Desktop Application that can let you minimize or close the connection. In other words, after you log in to your Ubuntu using full-display, you can only see the remote desktop. But the problem is that you might want to change the full screen mode to a window mode so that you can switch to other window without disconnecting the remote connection.

Here's how to do it, after you have log in to your Ubuntu using the remote desktop application, press Ctrl+Alt+Enter and congratulation you have change the full screen mode to window mode.
