  • Paul Tagliamonte: Framing data (Part 4/5)

    This post is part of a series called "PACKRAT". If this is the first post you've found, it'd be worth reading the intro post first and then looking over all posts in the series.
    In the last post, we we were able to build a functioning Layer 1 PHY where we can encode symbols to transmit, and receive symbols on the other end, we’re now at the point where we can encode and decode those symbols as bits and frame blocks of data, marking them with a Sender and a Destination for routing to the right host(s). This is a “Layer 2” scheme in the OSI model, which is otherwise known as the Data Link Layer. You’re using one to view this website right now – I’m willing to bet your data is going through an Ethernet layer 2 as well as WiFi or maybe a cellular data protocol like 5G or LTE.

There's something special about maps. I remember opening the front book cover of JRR Tolkien's The Hobbit when I was younger, staring at the hand-drawn map of Middle Earth, and feeling the wealth of possibility contained in the simple drawing. Aside from their obvious purpose of actually describing where things are in relation to other things, I think maps do a great job of expressing potential. You could step outside and take the road this way or that way, and if you do, just think of all the new and exciting things you'll be able to see.

  • Add Second Disk to Existing TrueNAS Pool in Mirror Configuration (RAID1)

    We are using the TrueNAS homelab server that we created some time ago to provide a share storage solution for Kubernetes.

    In the last post, we worked through how to generate a BPSK signal, and hopefully transmit it using one of our SDRs. Let’s take that and move on to Receiving BPSK and turning that back into symbols!

    Demodulating BPSK data is a bit more tricky than transmitting BPSK data, mostly due to tedious facts of life such as space, time, and hardware built with compromises because not doing that makes the problem impossible. Unfortunately, it’s now our job to work within our imperfect world to recover perfect data. We need to handle the addition of noise, differences in frequency, clock synchronization and interference in order to recover our information. This makes life a lot harder than when we transmit information, and as a result, a lot more complex.

  6. Convert audio in batches on Linux with SoundConverter | Opensource.com

    There are many file formats used to store digital audio, and they're good for different purposes. Digital audio is, of course, only a representation of sound, a rendering of soundwaves that get translated into sound by a decoder and a set of speakers. Some audio formats, generically called lossless formats, aim to encode audio close to its original analog form. Still, there's a lot of data in the real world, and as yet, digital can only approximate it in very large files. Other audio formats, called lossy formats, balance file size with a reasonable representation of sound.

    There are plenty of great terminal commands for audio conversion. There's sox and ffmpeg and a handful of format-specific encoders, like opusenc, flac, oggenc, fdkaac, wavpack, and countless others.

That's where Flowblade really excels. It's a simple editor that can do all the basic tasks you need, plus quite a bit more. However, it focuses on the essentials so you can get started editing right away, and you're never likely to be overwhelmed by menu selections you may never use, much less understand.

  8. How to migrate from CentOS 8 to CentOS stream conversion

    As you know, CentOS 8 is ending soon. Red Hat is making the shift from CentOS 8 to CentOS Stream. CentOS stream places itself between Fedora Linux and RHEL. It is not 100% RHEL clone but ahead of RHEL development. Think of it as a midstream distro. Of course, if you need 100% RHEL compatibility, then you need Rocky Linux or AlmaLinux. However, the CentOS stream is more than sufficient for me as I only need Apache, Perl, and Python for my use case. This page explains how to migrate the existing installation of CentOS 8 stable to CentOS Stream without reinstalling a new operating system.

    CentOS Stream is an open-source operating system and one of the replacement candidates for CentOS 8. However, I decided to stick with CentOS Stream because I didn’t have time or energy to install a new replacement such as Rocky Linux or AlmaLinux. Then restore data. It is too much work for my side project. Eventually, I will convert my legacy app to Docker format, but for now, I am going to upgrade my VM and save some time. So without further ado, let us see how to migrate from CentOS 8 to CentOS Stream using the ssh command.
