On a Lenovo Thinkpad the trackpad is the red button that acts as a mouse. To set the sensistivity and speed of your trackpad on for ubuntu/debian linux do (as root):

echo -n 180 > /sys/devices/platform/i8042/serio1/speed echo -n 250 > /sys/devices/platform/i8042/serio1/sensitivity

Lenovo X61s Battery Life

By Rufus Pollock On April 30, 2010 · Leave a Comment

I have a 2y old Lenovo X61s running ubuntu jaunty. Ever since I acquired I’ve been rather unimpressed by battery life-time which seems to be max 1.25-1.5h (2h if I’ve just got it on but not doing anything). This lifetime is achieved when:

I recently took delivery of a Novatech X40r system (Novatech are one of the few suppliers who allow me to get a machine without Windows). The most recent version of Ubuntu (Gutsy) installed without any issues — though I couldn’t quite seem to get the display resolution to match the screen resolution. Next step was [...]

Counting Words in a Latex File

By Rufus Pollock On August 24, 2007 · 1 Comment

Much of this was inspired by this blog post. Having tested on my own set of files I would suggest that these methods could be ranked in order of accuracy as:

TexCount.pl untex + wc wc pdf file wc $ wc -w file.tex

csv2ascii: display csv as ascii tables

By Rufus Pollock On October 13, 2006 · Leave a Comment

Having looked around for a while without success for something that would spit out csv files as ascii tables I decided to hack something together. The result is a small python script csv2ascii.py.

Archiving for my own benefit the results of yet another 5 minute look for how to do find and replace across multiple files from the command line:

Use sed:

sed -i ‘s/foo/foo_bar/g’ *.html

use the old perl hack:

perl -w -pi~ -e ‘s/foo/bar/’ [files]

Notes: -p: loop, -i edit files in place (backup with extension [...]
