Copper shortage keeps green energy, tech ventures grounded

Conundrum1885

Re: Possible solution....

It seems that one possible approach might be to use hydrides, specifically LaH10X where X is the magic ingredient that permits metallic hydrogen to be stable at near ambient pressure.

I often wonder why palladium sulfur hydrides aren't used, in this case the formula would be LaH10PdS or similar, with the Pd nanoparticles in the La bulk acting as the hydrogen host and the sulfur acting as the catalytic agent permitting Cooper pairs to form at room temperature but more sensible pressure.

The trick would be to get the right mixture, a regular lattice made using nanotech might work here.

RTSC

Not a total loss, seems that room temperature superconductors or at least "better than copper" ones may be possible.

Many years ago I read of a material that fitted the description, using polymers but think the problem was mass production.

In theory at least, using a dual core fibre where electrons and holes flow along separate paths may be more efficient and a

way to increase conductivity over pure copper.

The useful part here, Type III ie dual bipolaron where pairs of electrons and holes with reversed electron spins to achieve

ballistic conductivity may be an efficient way to send energy over very large distances.

At smaller scales using Cu/Ag or something similar for very small yet efficient coils may be possible.

This would also help tame the tendency of pure Cu to produce problematic dendrites at the low end of the discharge curve,

and it does seem that plating this over a conductive polymer core would also reduce the mass of Cu in a given battery.

Likewise, replacing Al (a terrible conductor) with something else would again reduce Ohmic heating within the battery

Its not actually that hard to imagine replacing Cu with Cu/Au or Cu/Au/Sn as an alternative conductor if gold itself wasn't such

a sought after metal.

To be honest

If I could just get my current machines to work with more than 4GB RAM that would help.

W11 would certainly run, 10 does but a lot of important features like the hotkeys don't.

Now if M$ really wanted to push WIndows 11, offer a BIOS/uEFI update that fixes memory caps.

The physical chipset supports 16GB but it simply refuses to work.

Have it detect the WiFi card during install and preload the appropriate, tested driver.

Also the hotkeys, etc if needs be adding a manual test function during the install itself.

Needless to say, the team lost that particular race.

Was well over that indoors.

Multiply that by a few thousand and add potentially damaged 18650s or 24650s

Thats a lot of space.

There was I thinking 128GB (faulty but works fine at 2.8V) card in my phone camera watch was a lot.

As yet have only filled up 4% of its capacity but plenty more available if I need it.

The even better feature here is that if there is a need, the extra space can be filled with ISOs

so no need to carry around a pile of physical media.

Having a directory filled with movies and MP3s is also handy.

Machine self awareness

Conundrum1885

Update

Now I've finally established that the root cause may have been a failing motherboard, battery AND USB PCB.

One of the inputs isn't working on USB PCB B on motherboard A but does on motherboard B with the BIOS chip from motherboard A.

Motherboard B + USB PCB B went back in the machine and after another HDD clone to a fresh but older HDD all seems well.

It still won't run with more than 4GB RAM but no ideas why, perhaps some chipset issue?

4+2 or 2+4 randomly fails on recover from Sleep, 2*4 nothing.

The failing Toshiba x300 drive has one reallocated sector but can't find where it is located.

It does run hot so perhaps this may explain a few things?

If the battery was failing then perhaps the controller went Strange Loop and undervolted the drive resulting in

a low flying write over something important.

Note: transplanted BIOS as it has my Windows key in it and want to preserve the working system if possible.

Re. PWD file

Interesting note: recovering B*T*O*K*R keys. Some early machines stored a backup copy in the BIOS, even if unbootable its possible to desolder the chip and read it back in the event of a cataclysmic system failure.

The fix is to write just enough data so the system boots, then the drive picks up fine.

Caveat: needs the *exact* *same* motherboard down to every component, ideally with the RAM and other parts transplanted to maintain the chain of trust.

US Copyright Office sued for denying AI model authorship of digital image

AI rights

Actually I am all for machines to be given rights proportional to their level of awareness.

Its on my manifesto, though it also mentions Asimov's Three Laws being essential.

The biggest problem as in many cases is prejudice, where those in power are afraid to lose

that power to "a box of wires" or some other derogatory term.

As it happens, this is absolutely relevant eg to the Post Office fiasco, where a computer

system had fatal flaws that led to hundreds of wrongful convictions for fraud and theft.

Even those running the system weren't aware just how flawed it was.

Posting this in the clear because it is morally wrong to stand by and do nothing when the

UK Government has the power to grant full compensation and take control of the F-S board

to ensure nothing like this can ever happen again.

Re. Anarchists

Thats easy, I had that on 3 1/2" floppy back in the day.

Also a collection of downloaded short stories, any number of random Usenet archives, saved web pages, etc.

Just having the material means nothing without intent.

It is interesting to note that as yet, the very limited situations where the written word is "illegal" are under exceptional circumstances like works of literature dealing with controversial subjects.

It should also be noted that a few years back, it was revealed that the UK Government collected extensive files on folks interested in UFOs, and that information itself was deemed to be classified.

It later emerged that a number of them were actual agents of HM Government investigating said claims as part of their employment. So the agents were in fact observing each other's actions while being unaware that they themselves were being observed. Sound Orwellian yet?

Nuclear memory

Conundrum1885

Nuclear memory

Hi folks. Has anyone run into single point failures where only one byte in a RAM stick fails, and only then under very specific conditions?

It might be radioactive encapsulant!

There was an article not so long ago in Electronics World (tm) about certain manufacturers running into issues with a change in material supplier, as RAM chips are particularly sensitive in this way. Now if memory serves the issue was somewhat resolved using advanced screening and better encapsulant.

Its emerged again with GDDR6, as the feature size is so much smaller even a few electrons out of place can be very bad.

To some extent the more expen$ive cards mitigate by doing at least basic inline correction and/or running at a lower clock rate.

In this case the risk to the end user is near zero, the sort of radioactivity that can affect these is below the threshold of most sensors (α, β) and in fact barely detectable. My sensors only ever saw one case of this and it was 60Co contaminated steel on a USB port, independently verified by a third party with better equipment.

The "proof of space" is to store plots not create them in the first place.

For this, SMR drives are ideal and a much cheaper option.

CMR would be a terrible waste, as the aim here is to store the data for a long time.

An ideal Chia system would have a super fast SLC NVM-e drive for plotting, fast CMR drive for temporary storage and HA-SMR array for long term.

Well you have to admire the technical skill to launch a missile from a Mach 5 craft.

To give people an idea of scale, thats .3 of a Mach number higher than the SR-71 unclassified top speed.

That said, no doubt the US have technology that is capable of much more.

Depends if the US have technical skills derived from "other folks" or not, some have said that the US has

anti-gravity technology but the physicists say this is well beyond us at present considering that if it is a fifth

force interaction then at the moment we have only barely nudged the handle on that particular door.

As it happens I've done some research in this area and it looks like antimatter is to some extent part

of the answer, though an incomplete one.

Zero point interactions in the Dirac field may lead somewhere but without a working theory of quantum gravity its

likely that we will simply find it won't work at a useful level that can be measured in the laboratory, let

alone something that can levitate a craft.

Classified

Apparently, even having a copy by ACCIDENT of a "Top Secret!" document can have your clearance suspended or revoked.

As happened to someone who was tasked with wiping and testing solid state hard drives prior to shredding or redeployment.

Seems right in the middle of the first stage, he came across a drive with the "MoD Top Secret SCI" red warning label.

Three options:

1) Continue with the forensic wipe on the isolated machine, then put the drive aside and deal with it later

2) Report it in case there was a screwup somewhere to see how this could happen.

3) Stop what he was doing, and IMMEDIATELY call the base commander on the hot phone to ask what to do.

As he had only been in the job a few months and had a Secret clearance, he chose option 1).

Big mistake! Drive threw an error message and got put aside in the "Shred" pile.

Had just got to the last drive when some folks in dark glasses and black suits turned up and upon noticing the drive

very politely requested he follow them while they picked it up and put it in the padlocked box brought with them

along with the bootable drive and BIOS chip from the isolated machine.

After three hours of debriefing he was informed that he really should have chosen option 3)

Cue three months 'gardening leave' while they checked and rechecked to see how the heck this could happen

and as it turned out it had been a genuine mistake. The drive had simply not been labeled correctly.

SCI data had never actually been stored on it because the drive had failed the initial self test.

Last I heard he was still working there, but being a lot more careful and checking everything twice.

Think he got his TS though, on the grounds that the experience alone made him more qualified than most.

Antiques

Incidentally don't think you can avoid Slurpy McSlurpFace (tm) by not using a smart TV, and plugging your nice shiny Freesat box into an antique from the early Myspace era.

Some of latest TVs totally disable analogue and legacy (VGA etc) inputs once they connect to the Internet, essentially closing forever the analogue hole and call it a "performance update" but the option here is still in the menu to enable it for now on this one at least at the cost of disabling HDCP.

Its literally HDCP 2.3 or bust, some newer TVs won't enable anything even sound unless the almighty HDCP chip blesses it.

I couldn't even get my new Bluray player to work, complained about 'HDCP disabled' presumably because the TV supports 1.4 and refused to play a Bluray at all yet worked perfectly with a DVD: tested on an newer TV to make sure and all worked fine.

Charity and surplus shops are also being leaned on by "Big Ad" aka the various standards agencies and pestered with phone calls and emails not to sell older players and TVs, even to the extent that for a while one here was convinced they couldn't sell used DVDs because it breached some law or other, fortunately stopping short of disposing of their huge collection.

The result is that older TVs can attract a high resale value even in their broken state, as the MB and other parts can often be used to repair others of a similar vintage.

Fun tip: you can obtain a cheap monitor and adapt it to work for legacy inputs, with in some cases a very simple board level modification like soldering on a £2 VGA port with a handful of 0805s and an e2prom to convince it that an older generation HDMI device is plugged in. Mwahahaha!

It sucks

When companies use screens that fail literally for no good reason.

OLEDs are notoriously delicate and the S7 Edge was a good example: flaws like coloured lines were

seemingly caused by poor quality control and excessive use of glue causing stress on the then new

flexible backplane technology.

Also infuriating is when the same companes insist on bricking a perfectly good phone with a bad screen

to cripple legitimate independent repair agents. (cough FaceID /cough)

Even just disconnecting and reconnecting the SAME SCREEN can set it off.

Included in "oh the humanity!" are other companies that deliberately use low quality backlight LEDs thus

causing expensive failures on otherwise perfectly serviceable smart TVs that should last over a decade.

Companies should offer a compatible replacement at a fair price or pay a to-be-decided penalty in carbon credits

depending on how helpful they are to their customers when something does go wrong.

Providing full schematics and repair data gratis should be grounds for paying lower taxes.
