This is a collection of working commandline examples to show how one could use FFMpeg and VLC for live transcoding of video streams. All examples have been tested on OSX 10.7.5 with FFMPeg 1.1.3 and VLC 2.0.5 in early 2013.

An example network service with systemd-activated socket in Python. #systemd #python #socket #socket-activation
README
The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to
create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.
An example server
Create an simple echo server at /opt/foo/serve.py.

Multiplatform (amd64 and arm) Kubernetes cluster setup
The official guide for setting up Kubernetes using kubeadm works well for clusters of one architecture. But, the main problem that crops up is the kube-proxy image defaults to the architecture of the master node (where kubeadm was run in the first place).
This causes issues when arm nodes join the cluster, as they will try to execute the amd64 version of kube-proxy, and will fail.
It turns out that the pod running kube-proxy is configured using a DaemonSet. With a small edit to the configuration, it's possible to create multiple DaemonSets—one for each architecture.
