MacOS Combine PDF's Documents

Combining multiple PDF documents on MacOS is included with MacOS.

Turns out Apple included an Automator script for "Combine PDF Pages" with the OS and a Python script in the same folder.

So from terminal, you simply call the Python script and supply the output file (-o) with the input files.

/System/Library/Automator/Combine\ PDF\ Pages.action/Contents/Resources/join.py -o {output.pdf} {input1.pdf} {input2.pdf} {input3.pdf} {...}

A lot simpler and quicker than some other solutions.

Netdata + SNMP + Mikrotik

Always wanted to see my Internet line usage as a gauge without having to log into the router.
So today I configured SNMP in Netdata to collect from my Mikrotik router.

CasparCG Simple Playlist

It is possible to build a simple playlist as a rundown in the CasparCG client. It will very simply play each item after each other that are on the same layer. In this very simple post I show how to build such a playlist including the very important step of activating the OSC.

The Open Sound Control (OSC) implementation is how the client knows what the server is doing and then being able to send new command back to the server when a piece of media has ended to trigger playback of the next piece. For more details on the OCS, please see http://casparcg.com/wiki/CasparCG_OSC_Protocol
