How to migrate mysql-user/permissions

Sometimes we have to migrate some tables from one host to another. And sometimes we want to migrate users as well. This is how I managed to do this..

First let's read out all users


mysql --batch --skip-column-names -e "SELECT user, host FROM user" mysql

Output:

HackADay: Listening to Spotify on my Pi using A2DP

I installed Raspbian(Debian Jessie) with Kodi on my Raspberry Pi and I use my Pi as a Meda Center. This Media Center plays music, mostly radio stations, all day long. I can easily control this media-center using the Yatse-App on my phone. The Setup is almost perfect, but just almost. Sometimes I prefer to listen to my Spotify-Playlists. At the moment there are no really good music addons for that. So I came to the idea to pair my phone via bluetooth with my Pi and use the audio output of my phone to play the Spotify-playlists.

i3wm

I used Fluxbox/Blackbox wm for more than 10 years. It's a great window manager for people who prefer a lightweight system and love to customize their system. Now it was time for a change...

How to find out the serial number of a specific disk

To find out the serial number of a disk I mostly use one of the following commands:


/sbin/udevadm info --query=property --name=sdb | grep ID_SERIAL
## or
hdparm -i /dev/sdb | grep SerialNo

Suricata Ruby-Gem

I wrote a Ruby-Gem for suricata. It offers classes to parse suricata-logs and ships with a nagios-plugin

Creating screenshots using imagemagick

Normally I don't use the "print"-key on my keyboard. I woud like to use it to quickly create screenshots. So I'll map the following command to my .fluxbox/keys-file:


sleep 5s && import /home/dr/Screenshots/`date +%F-%T`.jpg

After 5 seconds of idle-time this command will activate a screenshot. After the cursor changed I can select a window or a region on my screen. The screenshot will be saved with it's date and time under /home/dr/Screenshots.
