I work in a relatively safe environment, yet it may very well happen that I need to prove something that someone said in my office, so I can hold it against them when the time comes. My laptop is always turned on, so I could use it to record the environmental sounds around it, with […]

How to drag and drop files between windows in Ubuntu Unity launcher bar

One huge gripe about unity though, is that you cannot, apparently, drag&drop files between applications open in the Unity launcher bar, namely: a file from nautilus into thunderbird as a mail attachment an image from nautilus into a photo-editing program the […]
