A Journey Through Discovery

  • Build Gqrx on Raspberry Pi 5

    Introduction I have a Raspberry Pi 5 Model B Rev 1.0, 8GB (info from raspi-config) running Debian GNU/Linux 12 (bookworm) (info from /etc/os-release). I am going to build Gqrx 2.17.6 as that is the newest release as of this writing. Due to the nature of open source software and how often things change, I am…

  • Build gr-osmosdr on Raspberry Pi 5

    Introduction This package adds libraries for software defined receivers (SDR) in gnuradio. I came across this when trying to get gqrx installed on a Raspberry Pi 5. Building this was fairly straight forward, luckily. The GitHub page had up to date instructions. (ref: https://github.com/Nuand/gr-osmosdr) Building With CMake

  • VMware Cloud Foundation 5.2 – Configuring SFTP Server

    Introduction I have a fresh installation of VMware Cloud Foundation (VCF) 5.2 installed and want to configure the SFTP server. This server is used for SDDC Manager and NSX Manager. Luckily, in this version, SDDC Manager should be able to communicate with modern SFTP servers using ECDSA SSH public key encryption. I have a post…

  • CubicSDR on Raspberry Pi OS (64-bit)

    Introduction Note: After numerous attempts to build CubicSDR from source on the Raspberry Pi, I was still unsuccessful. It’s unfortunate as this seemed like a promising application. I am publishing this as I may come back to it in the future, but for now, consider this post incomplete or containing inaccurate information. I picked up…

  • ESX Host Memory Sharing

    Introduction So first off, why did I call a host ESX in 2024? Well, because Broadcom changed the name back to ESX this year in October. However, as with many branding name changes, the User Interfaces (UI) don’t necessarily catch up right away. You will still see me refer to the ESXi Host Client in…

  • RTL-SDR Blog V4 Dipole Antenna Kit

    Introduction Since this was all new to me and the price was relatively attractive, I picked up the RTL-SDR Blog V4 kit from Amazon. I am based in the US, so it was convenient and extremely quick. I also purchased a Raspberry Pi 5 to use for my amateur radio hobby to keep things separate…

This is how it all started…

I started this site with the intent to aggregate as much information as possible in one place. I use this to record lessons learned or frustrating configurations I have experienced on the job or just tinkering (learning) and just couldn’t find a better resource available. I have tried to be as thorough and accurate as possible, but technology is rapidly evolving and every environment is different. I may miss things along the way and my setup most likely differs compared to yours.

I hope you find this site has some value to you.
