Evince: Open encrypted pdf documents

Evince is an all-in-one document reader to read pdf, ps, eps, dvi documents.

Advantages:

1) Loads faster than most pdf readers

2) Reads encrypted pdf documents (allows you to print protected documents)

3) Reads most of my normally used documents (specially when using Latex)

Do try it. It comes automatically with most linux (gnome) distributions.

Ubuntu: Faster bootup and performance

Unlike a server one does not need a lot of services to be running in the background on a laptop. The best way to speed up the boot time and performance on a ubuntu laptop will be to use the Boot-Up Manager.

You can install it by:

sudo apt-get install bum

In my laptop I disabled the following services which I do not use and I gained at least 8 seconds of boot up time. System wake up from sleep is also faster.

Service disabled:

stop-bootlogd
rsync
pppd-dns
cron
hotkey-setup
dns-clean
jetty
cups
apmd
atd
klogd
saned
bootlogd
sysklogd
bluetooth
