Backing up 4TB VM across the network, for a disk swap in a server...... Zzzzzzz      Donno why its so slow.  CPU on either box isn't taxed at all ( sub 10% ),  network is loafing @ 120mb on a 1g switch.. Every other VM is turned off to reduce bus traffic.  Drives are not high end but not super cheap either. Source is an SSD.. Destination drive on the backup server ( proxmox ) isn't the fastest around, it is a spinny disk to save cost but not slow either.   I forget the rates now, but i have tested the drives on the same hardware and it was several times write/read speed max and about ' average ' in the bigger picture.

Last time i did this it was onto an external USB as that was the largest disk i had handy ( 8tb ), so i did expect some slowness, even tho it was still USB3. But its about the same speed .. 

read: 123.3 MiB/s, write: 116.8 MiB/s   ( average update each block )

There is some compression going on, but with cpu so low, that isn't the bottleneck either.. 

Not end of world, its not like some mission critical NSA datacenter here..  mostly just my NAS and streaming front end so i can watch videos and music on the big screen...  just seems odd to me.

Apparently its not just me. Others have similar issues.  Something i may look into more someday and give the dev guys facts/ideas.  But will want to test on true server level hardware, eliminate any possible workstation level bus  bottlenecks.

If i ever go back to consulting, ill do some other form of backup ( perhaps images for the regular VMs and rsync for the NAS ). As convenient as it is, cant have a production box down for many hours on a restore that should not take long. ( ya, i know, 4TB isn't going to be quick, but still )

whoohoo my 3d printer still works. Not had it on since fall when i had to tear it down and rebuild the hot end.  ( filament leak. what a freaking mess )

Still not sure why my AI bot asked for access this afternoon, or what its printing... 

Well darn,the law suits aside, looks like machines with snapdragon X are still now hitting the streets, but a bit high on the $ side.

2200 bucks. While i guess its not THAT bad if you are looking for a new non-intel machine, and it is faster than the M3, i think ill pass. Not like i would have to skip meals or something to get one, its hard to rationalize that much for a toy that would rarely get used. ( even if i was still going into office, it would be 'used' .. but still just be a toy there, to use at lunch to look at email and watch video, which my 300 dollar Chromebook does just fine. 

sort of a shame, hardware we only could dream about not too long ago..  dont need it now. 

That 2.2k was for Asus, which is normally lower priced than most.  But just got an ad from Lenovo. Their base X model is 1.2k. Still more than id pay for a mostly useless toy ( if i wanted to burn cash, I'd spend it on more GPU for my AI server first ) but that is much more reasonable i think for an entry level model.

Well that is cool.  OrangePI has come out with a CM4 compatible board with a real chip ( RK3588 ) and upwards of 16G ram, 256G eMMC.  Couple that with the 6 port 'cluster board' that is miniATX sized ( and it also adds 6 M.2 slots for storage ).. 

Would not be cheap ( my guess is around 1k ), but would be cool.

Tossing old stuff today, including some of the few books/magazines i kept from the great purge.

Old "computer design' Magazine ( i think IEEE, i used to be a member around that time frame ). March 1, 1987.  Headline on cover: Future Computers to use optics and neural nets.

Well, not there yet for optical computing, but they were not wrong about the neural nets, and coming optics. 

I guess this could be a rant too, but a question:

WTF is the point of these stupid clover style power plugs? Why cant everyone just use the old blob style?    What does it offer that is better?        Long story but had one go dead on me. No physical stress, never imagined the AC side went out.   But it did. and of course since they are different, i don't have a bunch of spares laying around.( explains my pixel book troubles from a month or so ago. .i just could not bring myself to toss it yet.. and thought id try screwing with it again. )

You have the prong plug that goes in the wall like always on one end.  3 "pin" ( well 2 slot and one round, here in US at least other countries YMMV )

Normally the other end, which goes into the power supply/transformer/etc is a solid block with 3 slots. These newer things, instead of that its got round nodules and round pin holes .  They seem to be most common on external transformer type supplies  ( laptops and such, but i did see a PC with it too ) Most of mine, even laptops and these NUCs i have a plethora of, still have the old style, and i see NO advantage to changing.  It just doesn't make sense to me of why we are doing this unless there is some huge advantage im missing..

"Clover connectors" is what i see them being called, sort of silly, but i guess i do see where they get the idea from.

and i hate to do images, but:

No idea what you're talking about. Which end is a clover?

Oh all my battery charging transformers ( for those probable solar things so you can use line power ) are also the old style..      

That's a C5 connector.  It's actually from the same series of connectors (IEC 60320) that has the C13 you're familiar with for plugging in computer equipment.

its dumb :)

Dumb as i dont see any actual valid reason for it, other than to 'make more incompatible stuff'

Im ok with things when it makes sense.  but i dont see any advantage over the older style 

From your connector link i believe: C13/C14

it was on every AC powered device ( well, ones that were not hardwired ) i have had since the 80s..  until these dumbass flowery things started appearing. That dont even take the same amount of current. 

I meant to say 3 Pronged AC.  The 2 prong dont count for this mini0rant. But not had many of them. Just a handful. 

As always, I'm ok with change if you gain something, i just dont see any gain here.  In fact, with lower current ability, i see it as a loss.  Its not smaller, and less power..
