As you mention "microcontrollers in the signal-chain of a transceiver", I am currently looking into OpenRTX.

It is really a very nice example of exactly what you mention and something that has become possible to last 1 to 2 years. With these radios that support opensource firmware, It really has allowed amateurs a look of what is inside of the firmware of a "commercial-grade" handheld radio.

Two weeks ago, I helped out in an infobooth on Amateurradio at a makerfaire here in Belgium. Things like OpenRTX allow to explain to IT-people (who normally only work on computers) how "embedded software" works, how software that runs in devices we use everyday operates. In that sense, FOSS is as much an educational tool as it is "just a piece of code that does something".

I completely agree with your remarks.

For people who are interested in opensource and amateurradio, I propose you have a look at the conferences on that topic.

Overhere in Europe, there are two of them

• FOSDEM ("Free and Open Source Developers European Meeting") is a yearly event held in Brussels every 1st weekend of February. In the 2024 edition, there was a devroom ("developers room") on SDR and Amateur-radio. https://fosdem.org/2024/schedule/track/radio/

The videos of the talks are online. I propose to have a look at the talks on M17 and on OpenRTX.(*) Also open source hardware is becoming more interesting.

• Next september, we will be hosting "spectrum24", a new conference on "novel ways to use the spectrum we -as citizens- are able to use. It puts a lot of emphesis on Open-source as yes, most -if not all- of the new projects coming out in amateur-radio are open source.

For this conference, we are at the "cfp" (Call for Presentations) stage. See here: https://spectrum-conference.org/24/cfp

I know that Europe is the opposite side of the globe for you in Autralia. Perhaps there are similar events on your side of the world.

What was that saying again?

"the biggest thread to the safety and cybersecurity of the citizens of a country ... are managers who think that cybersecurity is just a number on an exellsheet"

(I don't know where I read this, but I think it really hits the nail on the head)

Yes. Fair point.

On the other hand, most of the disaster senarios you mention are solved by geographic redundancy: set up your backup // DRS storage in a datacenter far away from the primary service. A scenario where all services,in all datacenters managed by a could-provider are impacted is probably new.

It is something that, considering the current geopolical situation we are now it, -and that I assume will only become worse- that we should better keep in the back of our mind.

The issue is not cloud vs self-hosted. The question is "who has technical control over all the servers involved". If you would home-host a server and have a backup of that a network of your friend, if your username / password pops up on a infostealer-website, you will be equaly in problem!

Well, the issue here is that your backup may be physically in a different location (which you can ask to host your S3 backup storage in a different datacenter then the VMs), if the servers themselfs on which the service (VMs or S3) is hosted is managed by the same technical entity, then a ransomware attack on that company can affect both services.

So, get S3 storage for your backups from a completely different company?

I just wonder to what degree this will impact the bandwidth-usage of your VM if -say- you do a complete backup of your every day to a host that will be comsidered as "of-premises"

Hi,

What is the reason you do not want a domain? it is not that DNS-domains are that expensive these days. The cheapest option I found is .ovh (which is one of the major cloud-providers in France), which is 3 euro / year (+VAT). You can then put as much hosts or subdomains under it, and it supports dynamic IP.

Agreed, .ovh is not the most "professional" looking domain, but it depends on what you want to do. If your goal is simply to have something for yourself / family / friends, then this is good enough.

BTW. Having your own domain for a nextcloud instance has additional advances: you can get a real https/tls certificate from letsencrypt, and -if you put a reverse proxy in front of your NC- it shields you from people who just scan the complete IP-space of the internet but who do not know your domain.

The question is .. do we care about THAT 80 % of the people. I would be more then happy if we can have that 20 % of more technical-oriented audience :-)

or a one-way trip from a window on the 10th storey of a building all the way down to the ground.

A /48 is quite overkill for a home customer. Do you have 65536 LANs at home? Here in Belgium, we get a /56.

just out of interest .. somebody here on satellite? I am interested to know the prices for sat services out there?

I dan't know if this is still valid but I used to be told to have different partitions for your system, logs and data (home directories) .. and have the swap-partition located in between them. This was to limit the distance the head has to move when reading from your system starts swapping.

But if you use a SSD drive, that is not valid anymore of course :-)
