comment How do I delete the target of a symbolic link without deleting the link itself?
Alternatively, one can use realpath, which does in this case the same thing as readlink -f (but also works if the target itself is not a link).

comment How to securely ssh into a machine at home over the internet
“prevents most attempts at brute force attacks from the web“ – yeah... I have to say it's actually somewhat entertaining to monitor thousands of futile attemps to log in as root (which of course you should never allow).

comment Electric guitar through iRig in Ubuntu?
@markkirby: well, because there is an ALSA driver for your interface. Apparently one that comes with the alsa-common package, which is installed by default. Thus for you everything is fine, you don't even notice anything about ALSA. Unfortunately, it looks a lot like the OP has an interface that's not supported by ALSA, and then all the higher-level stuff like jack, let alone Rakarrack, is no use either.

comment Electric guitar through iRig in Ubuntu?
Note that jackd / jackd2 (qjackctl is a graphical interface to that and indeed has all necessary packages as dependecies) runs on top of the underlying ALSA architecture. Without ALSA drivers there's nothing you can do to get the interface running, as I already said in my answer. And, USB is irrelevant here, that's just one of multiple buses an interface / its drivers might use. You can use jack just as well with an internal sound card.

comment Electric guitar through iRig in Ubuntu?
Whether it's USB or Firewire or PCI is secondary; if there's a suitable ALSA driver it'll know how the interface is supposed to be connected. Only, I fear there isn't such a driver that would work for the iRig.

comment How to set the default program to open a certain file type in a certain folder?
Never use .jpeg as an intermediate format! It incurs generation loss. Why don't you just save the images as .xcf, which is always automatically opened with GIMP?

comment How to install Ubuntu on an old laptop missing its built-in display
Good question. But... have you considered trashing that laptop and getting a Raspberry Pi or BeagleBone Black to replace it? These single-board computers have gotten ridiculously cheap, and are beginning to rival older laptops performance-wise.

comment Beep in shell script not working?
Nice! I use export BEEP=/usr/share/sounds/ubuntu/stereo/dialog-information.ogg and alias beep='paplay $BEEP --volume=32768' now, that works well for me. (Note that you can override the volume with the beep alias, e.g. beep --volume=15000 plays at volume of -12dB.)

comment Does Ubuntu work on a Raspberry Pi Zero?
Right, the most obvious difference between Ubuntu and Raspbian is that the former defaults to Unity, while Raspian comes with LXDE. I instead use XFCE on both my laptop (Xubuntu) and my rpi2, and this way both operating systems feel almost exactly the same even in graphical mode.

This is the only acceptable answer. Unfortunately, the property doesn't seem available yet in Xfce 4.10.

comment How can I split an animated .gif file into its component frames?
It should be noted that (as of ImageMagick version 6.7.7) there seems to be some memory leak: do not attempt -coalesce with long .gif screencasts, it would probably consume all available memory and possibly hang your entire system.

comment Is it safe to install Ubuntu 12.04 alongside windows 7?
While I positively recommend co-installing Ubuntu to everyone with a Windows PC, I wouldn't call it “perfectly safe”. Yes, it usually works just fine if you don't get anything wrong – but wrong it can go easy enough! Indeed, the live CD (at least 14.04) has an option that will completely erase the HD, with all partitions, and not really warn you about it. Definitely make sure you have everything backed up (as you should of course always have, anyway!) before attempting this.
