Scalebar with background

To change the backgroundcolor, adjust the scalebgcolor variable to use the desired color. Add the following code to your preamble:

\usepackage{tikz}
\usepackage[usenames, dvipsnames]{color}
\definecolor{scalebgcolor}{rgb}{0.08,0.52,0.80}

Software for scientists

Some things takes much less time and stress once you know the right tool. Below, there is a community edited list of software for scientists.

Text editors

in General purpose text/code editors. It may be better to have a good editor for everything, than different ones for different languages, scripts, notes.

lsusb lists the fingerprint reader in the x240 as follows:

Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

There exists experimental driver support for this in a fork of libfprint for vfs5011 sensors, however you'll need to compile the driver yourself. To get the fingerprint sensor to work for lightdm login, su etc, follow these steps.

Install fingerprint-gui:

sudo add-apt-repository ppa:fingerprint/fingerprint-gui
