From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Selfhost offline software (lemmy.ml)

Recently in Spain we have suffered a complete power outage, with no electricity for a long time. Some were able to have power on their computers with generators, solar panels, etc. And I know you can have data connectivity with SDR or HAM radio. But my question here is, what are some good self-host/local offline software that we can have and use for when something like this happens. I know kiwix, and some other for manuals. Please feel free to share the ones you know and love, can be for any type of thing as long as it works completely offline, just name it. Of course for GNU/Linux (using Arch myself BTW). Thanks in advance.

Could you send ePub files over ham radio? Let’s forget about TCP-IP mesh networking like AREDN for now. That’s too easy. Let’s look at radio protocols. D-Star can run at 128 Kbps on the 23 cm band. That’s not too common. Drop down to HF and you’re looking at 9 Kbps via PACTOR-IV.

In comparison, landline dial-up modems topped out at around 56 Kbps.

Now, I’ve seen ePub files around 1-2 MB, but that’s with cover art, images, embedded fonts, and all that fun stuff. With enough patience, that can work. But, strip out all that, leaving behind plain text and XML, and you’ve got something much more manageable that can be sent relatively quickly.

I can’t speak for Spain, but in the U.S., the FCC recently removed most symbol rate restrictions, so we might be able to squeeze out a little more speed.
