In a world where it becomes increasingly important to think and act on situations where for various communication via traditional means is not that easy any more, then LoRa (Long Range) wireless networks have been steadily gaining ground: they use open frequencies and for some of these networks, their repeater structure is largely ran by communities of volunteers.
Both communities and devices have evolved so far that its not just for early adopters any more: mere mortals can use it too.
In the LoRa area, MeshCore looks to have become the successor of Meshtastic: [Wayback/Archive] MeshCore – Off grid mesh radio communications system.
The core difference between these two LoRa networks is explained in the Wikipedia article on MeshCore:
MeshCore is often compared with other LoRa-based mesh networking systems such as Meshtastic. While Meshtastic primarily relies on broadcast-style message flooding, MeshCore emphasizes structured routing roles and store-and-forward mechanisms, resulting in different scalability and energy-consumption characteristics.
Communication over the MeshCore network reminds me a lot of three things, in this chronological order:
I think about everything of MeshCore is open source; mostly hosted in the hierarchy at [Wayback/Archive] MeshCore · GitHub.
MeshCore is fairly young which means it will have growth pains, and some hardware pains (like a node being limited to about 500 messages/hour because of physical bandwidth limitations – smaller cells work better than the FidoNet hub/spoke model – see the Dutch section below) but it also cool to see it evolving.
This blog post is going to be long, as a lot of MeshCore information is spread around the interwebz, so there is a lot to link to.

Every now and then, documentation in source code requires an ASCII table. Sometimes table cells are spanning multiple rows or/and column.
TL;DR: The tools I tried did not support that, so manual labour is still needed.

A few notes after I helped updating [Wayback/Archive] Chocolatey Software | SetACL (Portable) 3.0.6.0 to version 3.1.2.0 and [Wayback/Archive] Updates glab from 1.22.0 to 1.24.1; fixes #2 by jpluimers · Pull Request #3 · corbob/ChocoPackages.
As the burden on maintainers (not just Chocolatey ones) is high, not all packages get updated soon after new underlying software versions arrive.
Which means the maintainers are often very happy when an occasional user helps and preferably sends in a pull request.
That brings me to the an important point IN DOCUMENTATION DO NOT LIMIT EXAMPELS TO ONLY ABBREVIATED PARAMETERS OR VERBS as that scares away occasional and novice users of your software.
Chocolatey documentation is no exception on this, hence this blog post meant for people other than maintaining chocolatey packages on a day to day base.

The people knowing about the really early Pascal history are a dying breed. So before I pass away (see the posts on my rectum cancer), let me post a few more links here that based on yesterday’s Trip down memory lane: book on p-Code based UCSD Pascal which I ended with:
I learned a few more things from [Wayback/Archive] What do you think about something like Pascal bytecode? (Page 2)
Here we go:

A while ago (actually, almost two years ago <g>), Chinese Sausage wrote the below answer; it’s on my research list to see if I can stream out my audio library:

When space drive IS a concern, then ogg (aoTuV version) is the best format quality-wise (to these ears), as it is more true to the original music source, and it leaves less noticeable noise artifacts than the other encoders. However, aac is almost just as good and also more compatible with mobile phones, iPod’s and other external players, so it is probably a better choice if you want to share your music files with anybody who is not computer savvy. The main thing I do not like about aac (at least HE-AAC) is that it does not support gapless playback, which is particularly annoying if you listen to live albums, or other music which has continuous playback.
At 64kbps though, there is none better than ogg aoTuV. Here is a link to the latest version, in case you want it.
Just replace the ogg.dll and vorbis.dll files to the existing ones in your encoding program (I use MediaMonkey to encode files to ogg).
Hope this helps!
