By default the “pinch open” and “close zoom” options are not working in Firefox on OSX. But it’s not that hard to enable the Firefox zoom settings, if you know how to do it…
Open Firefox
Go to a new tab, type in “about:config” and hit <Enter>.
Click the “I’ll be careful, I promise!” button.
You can now modify the related browser.gesture preferences by changing the values as stated below:
After running Squeezelite on my Raspberry Pi for a while, I thought it would be time to update Squeezelite to it’s latest version. And this is how I did it…
First you’ll have to login to your Raspberry Pi, you might want to open a terminal and use SSH…
If you don’t have a squeezelite folder, then create one! You can do this by using mkdir in your terminal:
Sometimes it can be handy to ‘see’, what is around you on a network. For instance when you’re using DHCP on a network and you want to find which addresses are already taken. Or you want to check whether specific machines are up and running… Of course there are various tools you can install or use, but there are times that you just can’t reach for the right tool(s)…
You don’t want to do a ping sweep for nothing ;-)…
Of course there is a way of ping sweeping from the command line 🙂 By simply using the ‘FOR’, ‘PIPE’ and ‘GREP’ commands in a clever way.
for i in {1..254}; do ping -c 1 -W 1 192.168.1.$i | grep ‘from’; done
Naturally you can stop the ping sweep by entering Ctrl+z

Webmin is a valuable tool used for the configuration of Linux-based servers. Webmin installs an HTTP-based GUI which you can get to by using port 10000 from a browser.
To install Webmin, you need to run the following commands in your Linux CLI:
In my search for using the WiiMote as a musical instrument, I found out it’s rather easy to set up your system to use the WiiMote as a mouse. Some of the steps needed to configure your system are actually the same, for being complete I’ll document all steps in this article.
Prerequisites (what you need to get it working):
Hardware
Computer able to run Ubuntu (I prefer Ubuntu Studio).
Bluetooth adapter (an adapter for using an open wireless protocol for exchanging data over short distances).
Wii Remote (also known as a wiimote, the primary controller for Nintendo’s Wii console)
Software
Ubuntu Studio (a multimedia editing/creation flavor of Ubuntu. It’s built for the GNU/Linux audio, video, and graphic enthusiast or professional)
CWiid(a collection of Linux tools written in C for interfacing to the Nintendo Wiimote)
Allright let’s get started :
Where possible I’ll provide the links to the necessary download locations.
You either have a pre-installed Bluetooth adapter on your computer or you can buy one in the shop (make sure it’s Linux compatible).
As we’re using Ubuntu Studio, you can download the DVD Image and burn it to DVD.
You should think over what you going to do with your configuration, repartition your hard disk (or don’t), and install Ubuntu Studio
Make sure you’ve got a Wii Remote with enough power.
Open a terminal session in Ubuntu then copy and paste the following instructions:
sudo apt-get install libcwiid1 lswm wmgui wminput
Sometimes it comes in handy to know your gear so, at this point, you can turn on the Wii remote to scan by pressing 1 and 2 simultaneously (all the lights will flash) then running:
hcitool scan
After you installed the necessary packages, you will be able to give it the first shot by entering wmgui in a terminal window
wmgui
Select “connect” from the file menu, press 1+2 on the Wiimote when prompted then click OK. Lights and rumble can be turned on and off from the controls menu, and which inputs are displayed from the settings menu. Using this, you can test the IR camera (I didn’t have infrared lights so I used a candle (BE VERY CAREFULL WITH OPEN FIRE IN AND AROUND YOUR LIVING AREA not to set the place on fire)), the accelerometers, and check the inputs from the Nunchuck or Classic Controller.
Now you know the basic set-up is working (your computer running Ubuntu Studio, your Bluetooth adapter, your Wii Remote, and the “connection” between it all).
From here on things are different, from the article about using the WiiMote as a musical instrument (check here).
For using the WiiMote as a mouse we need a mouse emulator (a small program that converts WiiMote output to mouse output) the one we are going to use is called uinput.
Before being able to use uinput we need to load it into the kernel, this can be done in two ways: manually after every reboot or we can load it every time the system starts up.
Manually
Copy and paste the following instructions:
sudo modprobe uinput
Loading it up every time the system starts up by adding uinput into /etc/modules:
gksudo gedit /etc/modules
Edit and save /etc/modules (mine looks like this)
Now reboot your system if you choose the latter option (editing /etc/modules).
We need the MAC-address of our WiiMote, there are multiple ways of getting this address:
hcitool scan lswm
Now we can start doing our mouse thing by telling wminput to listen to the right WiiMote (telling the WiiMote to listen to which MAC address) (make sure you use your own MAC-address !!!):
sudo wminput 00:24:F3:E3:E6:CD
(if you get the following error “unable to open uinput” try using the wminput command in SU mode as you didn’t have enough rights to use uinput).
Now you’re ready to rock and roll!!
Two more things:
You can close the terminal window if you want to
If you’re ready using your WiiMote press the off button on your Wiimote.
