Sometimes when you have a large terminal command, you need to change one character in the middle. The only way to do this is hold the back arrow until you reach the character. I was wondering if it was possible to skip words just like in OSX by holding ⌥ ←
The good news is this is possible by setting your keys bindings. Open preferences, select your profile and open the keys section. Now look for the⌥ ← sequence and double click.
When you use Vmware fusion for a while the virtual machine files could eat a lot of your disk space. Luckily Vmware fusion offers a process called disk shrinking. During this progress free disk space in your VM will be cleaned and the vmdk files will shrink.
I recently bought the Raspberry Pi 2 model B with a Western Digital Elements 1TB harddisk. When I booted the Pi, the USB harddisk makes tiny “clicks” and it seems the harddisk is not getting enough power so I needed to increase the power provided from the USB port.
The network is reached by a USB wifi dongle which also consumed some power. In order to provide enough power to the USB peripherals I bought a 2A power supply. The Pi is going to serve as a media center so I installed the OpenElec image.
After a couple of flights with the UAir R10 quadcopter you want to record your own flights / crashes. I own a compact camera but it has a lens sticking out when turned on. A crash could easily damage the front lens so I decided to work with a more compact device: my smartphone.
I could simply mount the phone to the R10 camera mount, but this leaves the screen unprotected. Therefore I decided to make my own phone protector out of an old air mail envelope.
On the forums I’ve read a some posts about prop savers and cutting the shaft down in order to use them properly. It turned out that with my prop savers, cutting down the shaft is unnecessary. I have used one of the rings which came with the propeller.
Only using a password for ssh might make your server a target for ssh brute force password cracking. Adding two factor authentication for ssh on your Ubuntu server makes this a lot harder for potential hackers.
Google provides a tool called Google Authenticator, which is available for both Android and iOS. This tool acts as a code generator for the two factor authentication.
Every time you login via ssh, the server will prompt you for a code which you read from Google Authenticator.
I recently bought the Spektrum DX6i remote for RC planes and helicopters. To avoid damaging my RC helicopter on the first flight, I decided to practice on the computer first. There is a cross platform RC simulator called Heli-X which works on Windows and OSX. With Heli-X you can fly helicopters and quadcopters. I use the demo version since the time limit of 10 minutes is enough.
