    Setting up STRF Data Capture & Processing

Author: Mark Jessop (VK5QI) vk5qi@rfhead.net
This guide provides information on how to capture FFT data using the strf toolset, process it to look for satellite signals, and finally compare their doppler shift against TLEs from the SpaceTrack database. This can help with resolving the 'TLE lottery' after new launches, or cataloguing transmissions from spacecraft already in orbit.
It should be noted that the analysis described in this document is but a small subset of what the strf tools are capable of! Scott Tilley has a post describing some of the history behind strf and giving a crash course on the relationship between orbital dynamics and the doppler effect here: https://skyriddles.wordpress.com/2019/01/04/basic-orbital-dynamics/
The target platform is Debian-based distributions (e.g. Debian, Raspbian, Ubuntu), but should be applicable to other Linux-based platforms. The data processing software (rfplot and rffit) is also k

    HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS.  That means no host downtime when managing your storage.
CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.
ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.
Installation


## gnuradio_install.sh
# This compiles and installs gnuradio including gnuradio-companion for MacOS.
# It uses homebrew (https://brew.sh/) for all non-python libraries and pyenv
# (https://github.com/pyenv/pyenv) for managing python.  I'm sure some of this
# would be easier if I used homebrew for python as well but I've found pyenv
# and standard pip to be less buggy in general.  However it does mean that for
# python packages that don't install with pip you need to download and compile
# the packages.
#
# Note that this script is not very robust yet, it's not made to run more than
# once (sorry).  ~If~ When you find bugs please let me know and we'll update

A demo python code that ..

1) Connects to an IP cam with RTSP
2) Draws RTP/NAL/H264 packets from the camera
3) Writes them to a file that can be read with any stock video player (say, mplayer, vlc & other ffmpeg based video-players)

Done for educative/demonstrative purposes, not for efficiency..!
