There would be a point if I had something else a new sparc could be doing. Until then two old bits of kit with almost zero resale value will keep things going, with no real problems unless both die at once, and even then the original SparcStation10 the original software runs on still turns on but is slowwwww.
A sparc VM on x86 that actually runs sparc solaris would be nice, and apparently such things were seen in the wild in the past but are unavailable now.

it''s about 'dblll' or is it 'dbIII'....trollers use screen names with lots of capital 'i' and lowercase

Look at the UID - I've had that account since before trolling was a problem here.
It is my second account but was set up because I lost the password to the old one (mandelbrute) and had it linked to an email address that I could no longer access - so I have not posted on the other account for something over a decade.

How is any of the above a troll? How is it even critical of you?
Just because you disagreed with me about the usefulness of X some time back enough to mark me "foe" should not be a reason why I can not discuss other unrelated issues where it even appears we agree, but I just have a bit more to add (look at Rei's post for detail, that poster has much more again to add on the subject and shows what I was attempting to convey).
And what's with the threat? If you feel you really are being trolled then just do it instead of threatening to do so.

so figure about 350w under typical usage

It doesn't work like that.
To use a car analogy that would be like assuming each car is moving ten tons all the time just because the motor can do it.

You'll also need to buy a lot of those pizza boxes to make up for the processing power that you can find in a box half its age, let alone the newer iron.

It entirely depends on what you are doing with it. If the task is not CPU bound on an old box you don't need a lot of them.
I've got one old sparc box for occasional use for some legacy software from 1996 and 2002 - it flies on a machine from around 2008. Another has a pile of old tape drives of various types hooked up to it, once again, for occasional use. The only gain in either situation from replacing them is theoretically increasing longevity. Neither case lends itself to a virtual machine unless the thing running that VM has a sparc processor, in which case there's no point for a VM.

If you're saying HP doesn't produce quality gear, you have apparently not used their servers

They also produce such crap that they have been fined for false and misleading conduct in relation to the sale of computer products (Australia's ACCC). It's difficult for the buyer to determine what is top notch HP gear and what is not based on what HP salesfolk are spouting.

in an all-Dell shop

Dell used to be mostly ASUS until ASUS went it alone. There's plenty of white-box vendors that are very good in certain segments so are worth looking at before playing potluck with HP (or Dell) who will always have something to sell to you whether it's what you are really after or not.

"if scaled up, this setup will not require complex, costly systems to highly concentrate sunlight"

A parabolic mirror trough is an example of something that is not complex or costly.

That's already done with some of the more expensive photovoltaics.

Only if the conditions are right for them to come out of solution and stick. Graphite crucibles are used to melt steel, and even that doesn't stick very well once it solidifies.

Read what I wrote again - iron dome doesn't have to be good enough to stop SCUDs to stop these things. Clear enough yet?

you are changing the claim and then refuting it.

That's not me that's your fucking strawman you simplisitic git. Read what is written and don't put words in other people's mouths when what they write is not convenient enough.

I know Hamas isn't launching big fat slow SCUDS, but even so, technology has just gotten so much more precise & fast

Not the stuff Hamas has, it's very old technology that makes a SCUD look like something out of Science Fiction. They started off with stuff the Shah bought in the 1970s which Iran was giving away as being useless for Iranian purposes. They have moved on to cheap knockoffs off the same old technology. Since they get the stuff for free (via Saudi's etc stumping up the cash) and are trying to hit a country instead of specific targets they put up with it instead of somthing that can be aimed with precision like a SCUD or newer.

For their own sake, it is time to move on

They have been squeezed into a ghetto and there is nowhere to move on to each time an election brings another pogrom. It's not as if they can escape into Egypt.
The ancestors of the bunch of fascists running Israel at this point would be horrified by this situation, especially how each shooting fish in a barrel episode coincides with an election.

Bullshit. There are plenty of reasons but shooting down a commercial jet resulting in Putin wasting time dealing with the fallout is not a sensible reason no matter what loonies beyond the far right that want to restart the cold war think. Implying that there was an order from Moscow to shoot it down is beyond the far side of crazy IMHO.

Nice nitpick on an analogy. Can we discuss the point the analogy is making instead please?
