@M0YNG That said, if you want to use them as external drives, e.g. in containers, ZFS is probably not the way to go: A RAID-Z array is useless unless enough drives are connected simultaneously. Building a ZFS NAS box is easy, and I've done this on five different occasions, but ZFS spread over multiple external drives is generally not worth it.

@M0YNG

1. Very recent (2.4.0) versions of ZFS for Linux do allow you to add drives to a RAID-Z one by one, provided they are identical, but you have to start with at least two. Maybe three, need to check the manual...
2. There are benefits to ZFS other than RAID-Z, like checksums. You can also create duplicate copies within a single drive, though it only helps with some kinds of fault.

@budget_biochemist There was a technical reason, though. It was specifically that HTTP/HTML have become too extensive to actually implement afresh and consumed everything. Making something impossible to extend beyond a certain point was the explicitly stated goal, and that goal is impossible to reach with a defined subset of HTTP/HTML, precisely because it would be a subset, and thus the extant superset would be its extension.

It's a very (and needlessly) radical logic, but it is consistent.

@squirrel The peak of interest in Gemini passed around that 2 years ago mark. The idea of "scrap this edifice and let's see if we can do without" is not currently in zeitgeist, and the AI debacle became the trendy thing. (and stole the "Gemini" name too)

When the AI bubble explodes, I expect we'll see another wave of interest.

@OH3CUF Bluetooth is generally only an option on rigs that have it built in - you need both serial and HFP, you generally want it in one device, and while the Bluetooth spec allows this, there is almost never anything quite suitable or easy enough to hack into submission. I tried to design something based on an ESP32 and never got this off the ground either, because I got lost in the APIs.

@OH3CUF Generally, any USB isolator based on an ADUM chip will do. My profile background is actually a photo of a USB interface I made with one of these. Isolator+hub board, FTDI, sound card, wire directly together, assemble in one box, done.

If one isn't enough, however, only addressing the root cause will help you: in my experience, it is possible to disturb the USB bus controller itself with RFI. Bluetooth might not be sufficient to deal with that either.

Found the new primary source, finally. Why is it that I'm the only person I know who knows this exists? Why does it only have four stars? Seriously, people, you're going to make someone think you actually *talk* on your radios.

P.S. https://github.com/VK2ETA/RadioMsg too.

Observation of the day:

1GBit LAN, two machines next to each other on the same switch:

+ Iperf3 TCP over plain network tops out at 117 MB/s.
+ ZeroTier tops out at 108 MB/s.
+ Yggdrasil tops out at .... 116 MB/s!

These overlay networks are similar in capability, but ZeroTier is UDP, and Yggdrasil is TCP. Which would normally make Yggdrasil's performance worse!

But Yggdrasil has an MTU of 65535 on the inside and fragments after buffering. ZeroTier apparently fragments packets as they come in.

@bud_t This is generally not how these particular holders are used, though. They're more about filming yourself while you're talking into the camera and otherwise being Italian.^H^H^H need your hands.^H^H^H...well, you know what I mean.

Think DataKrash.

This will make any use of Internet in public context basically worthless, reshape the entirety of public sphere - because that's where it is right now - in ways I can only imagine, but not adequately predict.

Apartment building chat groups so popular around here have every chance to be the vehicle of reshaping culture.

The primary use of these will be producing bullshit, in quantities MUCH higher than those that exist now, all the power that went into training models will instead go into generating bullshit. All of it. Models will not get better, not for years, but they're good enough to fool most people as is, that's enough to flood the internet entirely.

All this computational power will end up in the hands of anyone with the spare money and an idea. In quantities sufficient to run LLMs but not train new ones (that takes ALL the compute) as well as break encryption (passwords are basically toast) and mine crypto.

So I had a vision of impending doom.

This happens often, mind you, so take it with a grain of salt.

See, when the AI bubble bursts, in addition to all the economic problems resulting from that, all those GPUs won't go to some landfill, investors will attempt to extract all the value possible from them. So they will rent them out, to recoup their losses -- it's a bit tough to resell datacenter hardware, much easier to rent it out at dirt cheap prices.

@bud_t I have one mounted above my bed on a swivel for reading.
Plus a tiny-tiny gamepad to flip pages/scroll.

@kb6nu My dedicated radio machines (to be fair, I only have exactly one Windows laptop to test Windows builds on, everything else has been Linux for a decade) were running Ubuntu since I got them.

In addition to installing things from repos, I have a special battery of scripts to build things from source, mostly to optimize for the specific CPU architecture. :) Saves battery in the field.

For logging, CQRLog, but look into QLog. adifmt is also indispensable.

@jonny In the end, enforcement of these regulations is on the regional authority that handles amateurs (FCC, Ofcom, etc.) and varies *wildly* from place to place. What can one get away with also varies wildly from place to place.

@jonny

* My on-air protocol is published, it's not encryption! You can get it behind a door. In a cellar. Marked with "Beware the leopard". Honest!
* Back in Soviet era and in Soviet regions, enforcement of topics allowed on the air was really tight. So people used to say "I have built an electronic key in a box sized 950mm by 24mm by 17mm."

@jonny For example:

* You are not obscuring the meaning of the transmission when you transmit a cryptographic signature.
* When the frequency is shared with the public (LPD, PMR in some places) and you're pumping your whole amateur's power allotment into your antenna without identifying yourself as an amateur, who is going to catch you and how?

@jonny It's a bit more complicated...

One, *as a radio amateur,* (i.e. while using radio amateur's privileges for frequencies, power levels, etc) cannot transmit in a way *obscuring the meaning* of the transmission. This is a worldwide regulation, established as part of international agreements within the whole UN/ITU thing.

The subtle distinctions outlined above go a long way.

@kb9ens Precisely my point. They're assuming perfect time when Doc Brown might know what WWV is, but whoever observed the lightning strike certainly didn't, while the precision of the big clock was never even established.

The trilogy is full of subtle detail otherwise, but this bit...
