The deployment of OpenStack is a complex task. The most important task at the beginning is to figure out what YOU (or the company you are working for) want to implement using OpenStack as a tool to provide infrastructure resources in a data center. Will the Openstack based cloud be used by your internal customers (the tenants) using a Web or CLI based API or is the Openstack cloud not seen by the tenants. In the last case, the cloud is only used by the IT department to make their working life more easy. But the “easy” has a high price – the added complexity.

TL;DR: Python is a (powerful) general purpose language in broad use, let's dive in and learn some control flow tips, standard library tricks, and common pitfalls.
1 Introduction
Python (and its libraries) are enormous. It is used for system automation, web applications, big data, analytics, and security software. This article aims to show off some lesser-known tricks to put you on the path to faster development, easier debugging, and general fun.
As with every language, the real resource you get once you learn it isn't a language-related superpower. It's the ability to use the idioms, libraries, and shared knowledge of the Python community.

This week I’m testing a lot with CephFS and one of the things I never tried was re-exporting CephFS using NFS-Ganesha and libcephfs.
NFS-Ganesha is a NFS server which runs in userspace. It has multiple backends (FSALs) it can use and libcephfs is one of them.
To stream video and audio from A20SOM-EVB, ffmpeg and crtmpserver are used. FFmpeg is used to encode the video and audio from A20SOM-EVB csi-camera and mic-in and then feed the stream to crtmpserver. Crtmpserver act as streaming server to provide rtmp stream for flash player, or rtsp stream for video player such as videolan.
If the csi camera is not yet functioning on the default debian distro, please follow my previous article how to enable csi-camera on A20SOM-EVB.
