Wine has support serial and parallel ports. They work fine. In recent versions of wine you don’t even have to set anything up. Just run ls -l ~/.wine/dosdevices/com* after running something in wine to see what the com port number is for your device. The ttyACM and ttyUSB ports are USB serial ports. The ttyS ports are hardware serial ports and they will probably show up even if your computer doesn’t have any.

The list of vulnerability mitigations for those old CPUs is going to be a mile long. They will probably have their performance cut in half or worse. Even a much newer CPU like Zen 1 takes a big performance hit.

You can disable mitigations, but then a malicious website could potentially steal sensitive information on that computer.

For home use, all I can think of is wireless video. 15 GB/s is faster than the fastest DisplayPort or HDMI versions. It could handle any resolution and refresh rate currently in use without any compression. That would be useful for VR headsets since they need low latency.

Because of all of the blobs it contains. That has caused a lot of people to not trust it.

You would think that RAM manufacturers would ramp up production. Hopefully the fact that they aren’t means the bubble is going to burst within a couple of years.

It crashed a lot when I played it on windows too. I tried playing it a couple of times, but always gave up partway through because it kept crashing. There are some mods that are supposed to help with stability, I should try it again and see if they fix it.

Hosting the site from home may be an option if symmetric fiber is available and the site doesn’t get a huge amount of traffic.

I would immediately return that as defective. I’d rather use that old 1980’s portable TV that’s been collecting dust in my closet since they shut down the analog TV broadcasts.

So start making more dumb TVs and speakers. That way they don’t need much memory.

The AM broadcast stations aren’t going anywhere, at least in the US. Above the broadcast band is mostly aircraft, marine and the 160 meter ham band. None of that is likely to change.

Below the AM broadcast band are non directional beacons. Those are slowly being decommissioned. Eventually they will all be gone and that spectrum may get repurposed. I don’t know what the spectrum may get used for, but it would be nice if the 630 meter ham band was expanded.

LF and MF can be used at low power. The 2200 meter ham band has a power limit of 1 watt EIRP and the 630 meter band has a limit of 1 or 5 watts EIRP depending on the country. Actually radiating that much power is difficult because it’s not practical to build an efficient antenna. Luckily there is no limit on how much power the amplifier can put out, so we can put hundreds of watts into a very inefficient antenna. Narrow band digital modes work great on those bands.

In the US, we have LowFER, which allows hobbyists to use 160-190 kHz for experimental use without a license. The power limit is 1 watt input and the transmitting antenna is limited to 15 meters. People still manage to make long distance contacts with those significant limitations.

For LF and MF, you typically want narrow signals, not spread spectrum. It’s hard to make wide band antennas for such low frequencies and propagation can change a lot in just a few tens of kHz.

Keep in mind that without working repeaters, the baofeng will only have a range of a few miles on level ground with nothing in the way. If the power goes out, most of the repeaters will go down too. Some have battery backups that may last a few hours to a few days. Depending on where you are, a few may be solar powered, but heavy use will drain the batteries. Some repeaters are also reliant on the internet for linking to increase the coverage area.

What you really want in that case is a portable HF radio and a wire antenna you can string up over a tree branch or a support with a fishing pole. In the daytime, you can use the upper HF bands for long distance communication. That has a range of thousands of miles, but nearby stations won’t be able to hear you if they are beyond line of sight. Since the portable radio doesn’t have much power, you may need to use digital modes to get through. For more local contacts you can use NVIS propagation on the lower HF bands. That has a range of several hundred miles and can even be used to talk to someone on the other side of a mountain. Even 5 watts and an antenna strung 3 feet off the ground can work for voice contacts out to over a hundred miles.

Windows XP is really lightweight. As long as your CPU supports VT-x or AMD-V, the VM will run fine.

CGNAT is a nasty hack to work around the shortage of IPv4 addresses. It’s not used with IPv6.

There would be nothing for one to connect to out here. There’s no WiFi except mine and no cell service unless you go outside.
I would probably desolder the antenna if I was in the city though.

Mine has never been connected to the internet.

There are a number of NPUs that plug into an m.2 slot. If those aren’t powerful enough, you can just use an eGPU.
I would rather not have to pay for an NPU that I’m probably not going to use.

This is one of the many reasons why you should never used cloud based cameras.

Keep your cameras and DVR on an isolated network with no internet access. Use a VPN if you need to access it remotely.

Having the buffers separate is useful because you can have two different things copied at the same time.

You could try. There are lots of open issues and the last commit was 5 years ago. It may have been abandoned.

I looked up the site on archive.org, but they don’t have any of the documentation pages archived. It looks like the documentation was just auto generated by gtk-doc, so you could clone the repo, install gtk-doc and generate the same documentation that was on the web site.
