On the server:

$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10
    234 really
     34 fg
     25 cd
     24 screen
     23 tail
     22 ls
     17 less
     16 spammer
     13 host
     11 man

Spammer is a simple shell function:

spammer() {
        really iptables -I INPUT -s $1 -j REJECT
}

On the laptop:

$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10
    297 echo
     62 ./graph-reduction
     53 darcs
     30 gdb
     10 make
      6 ssh
      6 LC_ALL=fi_FI@euro
      6 cd
      4 valgrind
      3 top

./graph-reduction is a program I wrote during the week. I’ll blog about it separately. the LC_ALL lines are likely all LC_ALL=fi_FI@euro luit slrn so that slrn would send Latin and not UTF-8 (the latter is strongly discouraged in sfnet).
