Synergy: One Mouse, One Keyboard, Multiple Machines (Ubuntu/OSX)
I am overjoyed and here is why. At home I have my main machine, which is a MacBook, and my secondary machine, which is my Ubuntu laptop. Both are on the same desk. My MacBook is connected to my Samsung Syncmaster 226BW monitor. My Ubuntu laptop is to the left of my monitor.
In the past, when I wanted to work on the Ubuntu laptop, I would fire up remote desktop on the Mac to access it, even though the laptop is about 50cm's to my left. The main reason I did this, is because I do not have any keyboard or mouse attached to the Ubuntu laptop, and trying to reach across is awkward. But no more, a great tool has solved my problem.
Fastest way to connect to an Ubuntu machine
Like many, I use a remote desktop viewer in order to connect to my Ubuntu machine. My Ubuntu machine serves as a media and file server, so I have it set up in the corner of my home office and never work at the machine directly. Instead, I connect to my from my MacBook.
Up until now, I used JollysFastVNC viewer. While this vnc viewer is a little fast than Chicken of the VNC, it's still not as fast as I would expect a local connection to be.
While browsing the Ubuntu forums however, I came across a great and super fast way to connect to an Ubuntu machine, from a Mac.
Mac OSX: Using rsync to make backups
I have been a heavy Mac user for about 3 years now. Throughout this time, I have attempted to use Time Machine on many occasions to make backups of my files. My experiences have been mixed.
