I am glad I did not get a Pi-5. I have had enough problems getting
the GUI to start up at boot time with my Pi-4B that I decided to just
run it in headless server mode.
The one thing I was missing on Pi-4 was a second ethernet port so I
could use it as a firewall/edge router with room for all the monitoring capabilities I could dream up to implement with PCAP.
Dongle-attached extra ethernet ports are a bit unstable in my
experience. Often have spotty Linux driver support, often get
redesigned with a different ethernet chip with no visible/noticeable
change in product name or packaging. Being on an ARM system makes the problems stemming from this several steps worse.

There's clearly something very convoluted about the
way the CPU and maybe some peripherial chips start
up on the Pi5. You could run many Linux distros on
Pi's up thru the Pi4. Then ... the factory Deb deriv
is pretty much IT unless you wanna suffer a lot.
If you've ever watched a Pi update, note ALL the
damned messages about special fix-ups and kernel
hacks - I mean there's LOTS of them. The BCM2712
do NOT boot smooth like earlier versions. I'll
still say the Pi3s were the "most generally useful".
As for the 16gb ... well, if it's not TOO much more
expensive, may as well have it. However 4gb has
always been more than enough for anything I've
wanted to do with a Pi.

An enclosure is purely cosmetic. I attached my Pi5 to a piece of

I can't understand your problems. I have two Pi4B and a Pi5 running
24/7. It is convenient that they all take the same version of
Raspian. @All three worked right up on the first boot. You do, however,
have to make sure you have a good power unit.

While attractive, some micro-PCs might be even better for that than a
Pi. Check SuperMicro - they have some very small boards/boxes that
are perfect for that kind of need. Impressive boards actually,
connectors for interfaces even I'd never heard of.

Sorry, mechanical design, 3D drafting - not in my skill set. And
neither I nor my friends have a 3D printer. And while it might be
interesting to learn, it is too much of a detour at my age of 74.
I could just buy a Protectli like the one I use at the office, but
things for the home should be cheap.
https://www.amazon.com/Firewall-Appliance-Gigabit-Celeron-AES-NI/dp/B07G9NHRGQ/
Looking at this, I see they have a two-port version for USD 219 with
32GB onbord storage, or USD 259 with 250GB NVMe. That is tempting.
The 4-porter at the office was a lot more expensive than that.
Spec says USB type C console port. I wonder how that works. Intended for
a USB-to-RS232 adapter?

I think its more the reverse, its during power on the problems arise, as they need fscking..
..Except mine doesn't. Since it is never written to. They key is to eliminate all writes to the SD card apart from unavoidable config changes. Stop logging or send it to a ram disk. If you need scratch files put those on ramdisk too.
I've got a full record somewhere of everything I did to turn off logging or redirect it to a ram log
If you can adjust your mindset to think of the SD card as EPROM, not a disk, it helps

It simplifies my life when all my Linux systems have the same system administration interfaces. I made the mistake of putting Centos 7 on a Wordpress server in the cloud that I set up for my daughter's kiddie pictures. It is now orphaned, and if I want to update it, I would have
to reverse engineer her customizations of Wordpress to back them up so I could do a complete reinstall transparently (to her).
Once my wife complains too loudly, this is _exactly_ what I will try! My estimate is that the next time the tape let's go, and it sort of sticks
out from behind the tv, that is the time I will be going down the velcro

boss wanted 'muzak' for the office. So, I took
an old Pi-1/256mb and a few long muzak tracks
from 70s shopping malls and sneaked the wiring
into the PA system. The tracks rotate every
month. Worked for a dozen years and likely STILL

the thing.
There was about an inch behind where the PBX system
was ... so I velcroed the unit to the back of the

Proper muzak - you shouldn't actually HEAR it unless
you TRY. Keeps some little corner of the brain occupied
and, according to some, thus actually improves performance
on other tasks.

I've never ordered from Vilros, but $10 with free shipping sounds good. Amazon carries a lot of Vilros stuff and it was a toss between that and Canakit for me, but not the mount. The mounts they do have are more expensive.
It's been my sad experience that unless I have the materials laying around DIY projects end up costing more in the long run.
Someone from Pink Floyd once commented that the reason
their music sounded so "different" was mostly because
their skills with their instruments was initially SO
poor - they COULDN'T emulate the popular bands :-)
Something really new - beyond 'space' and 'multiverses',
'galactic empires', dubious 'time travel' and 'AI' - will

All that stuff is old and creaky and over-exploited.

I heard that Queen's distinctive guitar sound came from
the fact that the only guitar and amp that Brian May
could originally afford was a cheap piece of crap.

No. He (and his dad) built his own guitar, but I think the pickups
were P90s. The amp was always a (number of) Vox AC30(s), well known for
a unique sound due to stuff you wouldn't be interested in

Hmm, I think going full circle is then the way to go. Dig up a concept
that has been forgotten for a 100 years or so, and perhaps it will be
nice and fresh! ;)
Two books on that theme are Flatland which is about a 2d world and
adding a few dimensions instead, there was a book by Greg Egan I think,
which was about uploaded virtual entities. Cannot remember the name at
the moment. I like that concept! I'm currently watching season 2 of
pantheon, and it's going downhill. In the virtual world they are using
way too many physical shortcuts to illustrate fights etc. It can of
course be argued that the brains of the virtual entities have not yet adapter, but I think that's a lazy excuse. It would be interesting to
think about if it would be possible to represent virtual uploaded
entities in a way that might make them seem more native to their world, instead of just reusing our physical world for easy comprehension.

Teilhard's mix kept him in hot water. His books never quite made it to the Index but he was not allowed to publish during his lifetime.

Not a bad idea - although even using that would ultimately
be 'derivative'.
There was some good pop music 100+ ago - including early
jazz/blues adaptations like 'ragtime'. COULD be kinda
punched-up.
Humans are 'creative' - but not infinitely creative.
Once in a while we'll hit on something 'new' - but,
due to exposure/recordings that's getting more rare.
I recall Paul Simon going to Africa in order to find
some 'new' sounds. Some of it worked, some didn't.

"FlatLand" is one of my faves. A much later writer did
"SphereLand" - delving into four dimensions.
What does a passing hypersphere look like ... like a
dot, then a bigger and bigger sphere - then a smaller
and smaller sphere - disappearing as a dot :-)
You'll have to look it up ... there was an author,
late 19th or early 20th, who made a book mostly
full of figures/drawings he claimed - after close
study - would help people wrap their brains around
4th dimensional shapes.
Easy! Meta-multiverse,
I call that "hyper-verse" or "poly-verse". We can more
easily imagine many, maybe millions, of other universes
spawned at the same time as ours, separate only by 4-D
barriers. But what if there are entire TREES of those,
no tree even remotely connected/nearby OUR tree ???
3.x-D universes smell of some kind of leak/defect/bubble
in the 10+ dimensional matrix. Kinda like a pot of
water on a stove, the 10-D starts making lower-D
"bubbles". Probably won't last forever, but forever
IS a kinda long time.
Where'd the 10+ D come from ? Dunno. Don't really
care. 'Causality' may mean nothing there. Best
to just say it IS there and if it wasn't then we
wouldn't be asking stupid questions.
Turtles all the way down .......

Not into 'spiritual' stuff since I was like 9. Had
one of those 'epiphany' things where all the whirring
bits momentarily fall in line and you can see through
to the (relatively boring/unromantic) truth.

Hey, we're tekkies here - we're interested in lots
of stuff 🙂
From May's sound, it's clear the amp has a somewhat
exaggerated higher-end response with some interesting
harmonics. A lot of the older transistor amps had
a kinda 'hard' sound too and kinda heavier on the
odd harmonics. Dunno if that was inherent, or
by-design - intentionally emulating the AC30 sound.
The wife loves jazz. Speaking of "new" I gave her an LP with Jan
Johansson called Jazz på svenska. It's a jazzification of old swedish
folk melodies. Quite relaxing, calm and melancholic. Kind of mirrors the swedish temperament I would say.

The AC30 is a development of the original Mullard application note to
use four EL84s - a small pentode - as a 25W power amplifier. Subesquent
units used a pair of EL34s.
Being British, when it needed more gain, instead of adding an extra
tube, they simply *removed the negative feedback* from the power amplifier. You don't care much about distortion in a guitar amplifier.
Of course this had another effect, instead of just increasing the gain
it increased the output impedance so much (~100ohm) that the
loudspeakers were practically current driven, rather than voltage driven.
This had two effects. The first one was a result of the induction of the loudspeaker voice coil. Normally with a constant volatage, you get constant-ish output with frequency. But with a high impedance feed the loudspeakers got effectively a 6dB per octave treble boost all the way
from somewhere around 1kHz. To tame this they added a simple 'tone
control' that rolled off the treble only.
The other effect was that the loudspeaker cone was no longer tightly controlled by the amplifier - it was free to flap. And it so happens
that the two 12" loudspeakers and the open backed cabinet had both a
nice woodenish cardboardy sort of sound and a massive bass resonance
peak at around 100Hz, which is very close to and lies between bottom E
and bottom A on the guitar.
All this made for a classic 'boom and chink' sound perfect for the beat groups of the era, and all with as few valves (tubes) as they could get
away with.
British amps sounded good because they were in fact BAD. Whilst a Fender
is a reasonable copy of a hi fi amplifier of the period, British designs
were over driven done on the cheap and had in many cases horrible
distortion.
The Marshall being the prime example of 'all of the above'. The classic 'attack' is caused by the amplifier having plenty of HT voltage - until
you want to sustain power. Then the mains transformers sighs and gives up.
So a 'power chord' has a sharp attack and then sustains at lower volume...

I like Nordic Revival bands like Garmana. I'm not sure I'd like jazz in
the mix.

Lemaître wasn't a Jesuit but he wasn't mixing science with theology. Teilhard strayed a long way from anthropology.
