How to remove all backups in Plesk for Linux

If you ever find yourself confronted with a Plesk system that is running out of disk space, and you just want to get rid off all the misconfigured "keep forever" backups, here's how to remove them all from the command line:

/usr/local/psa/admin/bin/pmm-ras --get-dump-list | egrep "name=\".*.xml" | awk -F '"' '{ print $2 }' | xargs -I {} /usr/local/psa/admin/bin/pmm-ras --verbose --debug --delete-dump --dump-specification={} --session-path=/var/log/plesk/PMM

Create a video clip from a set of images using ffmpeg

imagine your image folder looks like this:

rephlex@hera:[~/Schreibtisch/gna]: ls -1 * | head
G0037679.JPG
G0037680.JPG
G0037681.JPG
G0037682.JPG
G0037683.JPG
G0037684.JPG
G0037685.JPG
G0037686.JPG
G0037687.JPG
G0037688.JPG

[…]

This is the command you're looking for:

ffmpeg -framerate 25 -start_number 37679 -i G00%05d.JPG -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4

Installing Brother DCP Scanner Drivers in Ubuntu

Start a Terminal using CTRL+ALT+T. Install some depencencies and frontend scanner tools using

sudo apt-get install xsane sane-utils simple-scan lib32stdc++6

Now download the drivers. In case brother loses them, I mirrored them here. Alternatively use the wget commands down below.

wget http://download.brother.com/welcome/dlf006646/brscan4-0.4.4-4.i386.deb -O brscan4-0.4.4-4.i386.deb
wget http://download.brother.com/welcome/dlf006651/brscan-skey-0.2.4-1.i386.deb -O brscan-skey-0.2.4-1.i386.deb
wget http://download.brother.com/welcome/dlf006654/brother-udev-rule-type1-1.0.2-0.all.deb -O brother-udev-rule-type1-1.0.2-0.all.deb

Now install the drivers you just downloaded:

sudo dpkg -i –force-architecture brscan.deb brother-udev-rule.deb

And restart your udev service:

sudo systemctl restart udev.service

All i had to do was unplug and plug in my DCP, and i could immediately scan using simple-scan in Gnome.
