I'm out of space on /var

  25G   25G     0 100% /var


It looks like mlocate.db is the problem:

# find /var -printf '%s %p\n' | sort -nr | head
13140140032 ./lib/mlocate/mlocate.db.cgLMAM
12409839616 ./lib/mlocate/mlocate.db.MqGeqe

# cat /etc/updatedb.conf
PRUNE_BIND_MOUNTS="yes"
PRUNENAMES=".git .bzr .hg .svn"
PRUNEPATHS="/tmp /var/spool /media"
PRUNEFS="NFS nfs nfs4 rpc_pipefs afs binfmt_misc proc smbfs autofs iso9660 ncpfs coda devpts ftpfs devfs mfs shfs sysfs cifs lustre_lite tmpfs usbfs udf"


I don't see anything else to prune. So how can I fix this? Thanks


Question: Add authors as footnote in lncs
Answer: You might want to \protect the \footnote command. This one worked for me:

\documentclass{llncs}

\begin{document}

\title{LaTeX Template for Your LNCS Paper}

\author{Author 1\protect\footnote{Supervised by Author 9}, Author 2}

\institute{Lab, University, Address}
\maketitle

\begin{abstract}
Abstract is here.
\end{abstract}

\section{Introduction}\label{sec:Introduction}

The rest goes here.

\end{document}
