Extend laptop battery life in Linux?

I came across a thread at the Debian User Forums a while ago on this subject. One post there suggested installing TLP.

The Mint Guide suggests you need to run 

# tlp start

once to start it.

I don't use my laptop very much at the moment so I haven't been able to test it. At some point I will try to get round to doing a test and post an update, but if you find laptop battery life is poor compared to Windows, maybe try this.

Cancel print job in Gnome (Debian Stretch)

After over a year of using Debian Stretch, I finally found an issue to write about: it doesn't seem to be possible cancel a print job from the Printers dialogue in Gnome.

Possibly it's this bug, which seems to have been fixed just a few weeks previously to this post, so will still be affecting Stretch.

A solution I found here is to run the CUPS interface and delete the job from there:

http://localhost:631/jobs/

Cheers Zwets for that!
