Batteries are so heavy, said user. If I take it out, will this thing work?

Re: Hmmm :(

Very fortunately the contacts can't be reversed.

I have a dead "tough" Olympus here (u1020?) if anyone has a use, MB is fried.

Display etc are fine, pretty sure its an easy fix but symptoms are that it turns on then immediately off with "Low Battery" even with a new charged tested battery.

Also a more recent unit, this one has a bad screen and no sadly they aren't interchangeable.

£29 is a big chunk of change for such an old camera so its cooling its heels in "BOFH Hell" in a cement-and-plastic overcoat next to my unlicensed nuclear accelerator.

Do computers have NDEs?

Do computers have NDEs?

Hi all.

This may sound a bit esoteric, but what happens when a PC "dies" but then gets brought back by HDD cloning, component repair etc?

I'm talking full non bootable here, not just a simple restore from last known good.

Had a machine here like that, one day after strange problems it just failed completely.

Concluded that the HDD had failed irreparably and after various attempts ended up getting it cloned by a third party despite it not working properly (booted on similar MB but unable to copy user data)

Somehow (we don't know how) the 1TB drive did copy just barely and was useable afterwards but obviously had some problems.

Still using it now!

Data corruption seems to show that something bad happened during a routine update but based on the corruption pattern it was not merely a normal failure.

Ideas?

To be honest

W7 x32 may be old now but the hardware itself will run x64 fine.

I used 10 for a while on two of my machines but it really does suck, hard.

Problems that on W7 are inconvenient on 10 are totally catastrophic.

Flaky firmware and user rights to repair

Hi.

I am in the very unfortunate situation of having a "lemon" Freesat box which randomly crashes normally in the middle of a long film etc.

It has been used more than usual (ie on for 5-6 hours at a time) but not my fault.

Symptoms: can't get "Dave", several other Freesat channels and sometimes won't come out of standby and runs hot (45C+) also external hard drive never worked to the extent that it picked up the drive and tried to format then failed miserably.

Retailer claims that the drive "isn't big enough".. Uh, WTF?

I tried to update the firmware according to manufacturer instructions but nothing works, can't even get it to recognize any pendrive plugged in. Batteries in remote are brand new and tested.

Suspect it might be hardware but it was discounted a lot (down from £109 to £94) so it could have been an older model which never got updated

Is there any legal recourse I can take to force H*m*x into releasing a patch, as this is *really* annoying to effectively waste a week's salary on this junk.

Superconducting neural nets and sentient hardware

Superconducting neural nets and sentient hardware

https://phys.org/news/2018-01-nist-superconducting-synapse-piece-artificial.html

Seems that in 2017 there was a similar discovery, but using light propagation in place of resistance changes directly between large populations of artificial neurons.

https://physics.aps.org/synopsis-for/10.1103/PhysRevApplied.7.034013

Could this be a monumental step towards truly sentient machines?

It appears that Moore's Law has run out of steam and due to bugs like SPECTRE its now far too complex a problem to be resolved using conventional methods.

A possible construction might be a submicron (28nm) 2-D chip which is large enough not to be significantly affected by quantum effects, with the 3-D silicon/germanium funnel memristor arrays between them and interconnected through TSVs.

This would be "programmed" by the previously mentioned superconducting system which lays down the simpler pre-sentient pathways so that it does not have to start from scratch.

Heating would be far less of a problem due to the very high efficiency, as the whole brain might only need to run at <0.3V and areas not used can be turned off as needed.

Irony: a conventional laptop with a 3D-M array in place of its DDR4 chips might be able to organize and store information far more efficiently.

Perhaps even fix SPECTRE/Meltdown/etc on the fly by compensating for the performance loss incurred by breaking branch prediction.

Re. SPECTRE

No wonder Bitcoin went into full MELTDOWN.. investors probably realized that the current generation of miners had indeed hit the wall and they would not get any smaller without yields dropping to unacceptable levels. Last time I checked Bitmain had run into significant problems making the chips any smaller than 9nm and even Nvidia has decided to try and limit supply of their cards to miners.

https://forum.getpimp.org/topic/1196/nvidia-tries-to-limit-gpu-sales-to-cryptocurrency-miners

I would be concentrating on using current GPUs for deep learning and in fact there are commercial products available targeted at inference (cough Movidius /cough) and other custom chips for certain types of data but the more Tflops the better. A relevant piece of information is that the units in hospitals are often 2GB ancient cards due to the licensing and certification despite them being very primitive by modern standards.

SPECTRE/Meltdown

Conundrum1885

SPECTRE/Meltdown

Hi all.

Can anyone help please?

I have some ideas for a patch on Android devices abandoned due to age (ie Note 4) as discussed it should work by flushing unused areas of the chip with PRNGs effectively dummy data to prevent an exploit using speculative execution or other memory overflow variants exfiltrating data.

This is mainly because it seems a shame to simply discard hardware, a slight drop in efficiency would be a small price to pay and I can probably optimize it for Space Paranoids (tm) mode or just basic usage.

Ironically a BTc/Monero/etc miner by design might be a good starting point as it would pick up certain problems so a given core or cores can be "blacklisted" before it brings down the entire system.

Any ideas?

Re. infection

Actually I thought about this and it seems that part of the problem is that internal changes can be caused by a sterile (or very low bacteria) environment.

If so then simple custom probiotics might solve many issues, also using magnetic fields seems to help somewhat.

It may be that you only have to expose some of the body to gravitational acceleration and if so then this reduces needed field strength by an order of magnitude, within the range of permanent magnets.

Extreme laptop hacking

Hi all.

Just finished my mod on the C650D, now using 44% of the CPU and no apparent slowdown.

Before it was throttling even at 19% load on the Phenom 2.

Mod: replace existing 0.4A with a 0.5A fan containing double the blades.

Had to do some plastic butchery and modify the casing with fragments of a broken Ipad screen light spreader as they were just the right thickness.

Now for the warp drive: can I mod the BIOS so it does the following.

1) replace fan table with something a bit less primitive

2) have it boot from the internal SD as well as HDD and "BIOSBoot" so if all disks are unreadable the laptop still runs somewhat and contains a failsafe that can rebuild even onto a totally wiped drive

3) backs up all FATs, etc to failsafe storage *2 so in the event of malware the drive can still be salvaged.

Re: Please tell me

M$ seem to be really good at backing the loser: Surface,Windows Phone, HD-DVD, etc.

On the flip side HD-DVD modules are perfect for hacking PCB etchers and other DIY uses and a good way to get into UV lasers.

I made a 3 output PSU from my external which was useful for about maybe 2 years.

Fans got "recycled" to fix a pricey monitor with a bad IC, if you kept it cool no glitches.

What they should do is rebrand not simply abandon the technology. HD-DVD is still used for archiving (security through obscurity?) and Surface tablets are finding medical applications as cheap HD screens for hospital use or so it seems.

Nasty firmware update butchers Samsung smart TVs so bad, they have to be repaired

Conundrum1885

Bad chips!

I know why they broke: seems that the fault is a high density 8 pin flash chip similar to a laptop BIOS.

Problem seems to be that the timing is off and inadequate failsafes exist so portions of the memory are written incorrectly.

It was a trade-off between not having to wait for 1 hour+ for a "routine" update and having a bricked TV once in a while, usually it can be recovered but not this time.

Irony: reflashing 8 pin chips is quite simple with the right kit and I am working on a project to repair just this sort of failure using an internal "remote flash" rig that backs up firmware on the fly.

RE. Re.

I am aware that a lot of Kurzweil's writing is speculative science fiction, but up until maybe 2007 256GB on a fingernail was so ludicrous that people would question its existence by 2016.

The "wall" for memory chips was believed to be 4GB/in2 but this has since been revised.

Intriguingly my old Samsung Core 2 laptop seems to have a lot more processing power than first thought, those "wasted" 64 bit circuits are apparently being used despite running in 7 x32 mode.

Looks like this is why only 4GB is allowed, it would compromise the custom modded BIOS.

Once tried 7 x64 in error and it had issues, perhaps this has been fixed now?

The idea of using a quantum computer to "juice up" existing hardware is intriguing and worthy of further study.

Ai breakthrough "could lead to 2018 Singularity"

https://www.linkedin.com/pulse/something-monumental-just-happened-computing-one-paid-hiesboeck?trk=mp-reader-card

Not overhyping this honest but my 2016 estimate of 21/2/18 at 7.02 am for the Singularity might not be entirely inaccurate.

I have actual data here suggesting that a quantum computer could achieve some level of self awareness in conventional non-quantum hardware (eg DDR3/4) and this model shows that mapping out the memory to locate regions of maximum beneficial instability would work.

A conventional annealing setup probably wouldn't be enough, this would require the 50 qubit system but still a significant advance if the GTX1080Ti cards with 12GB RAM were used.

32 cards giving a total of 384GB RAM and running at maximum output would have the same intelligence as a two year old in certain tasks such as image recognition.

The DDR4 modification of address line randomization is a non issue as the algorithm is not in fact random but by design entirely predictable and I am in the process of modifying the system to work around it.

Those Movidius AI "sticks" might also be handy for a lower budget version as they are based loosely on Bitcoin miners which only recently became public knowledge and explains >8 month delay on release.

In this case 4 1080Ti's would be needed with a custom rig containing two AMD 1950X 18 core chips and 2C/4S per node, maxed out at 128GB RAM.

New physics

We don't yet know exactly how Jupiters field is generated.

It is possible that a super earth might have a far stronger magnetic field than Earth for the same reason; as the geodynamo could contain radically different mixes of metals. Earth has nickel iron but it could just as easily be nickel iron cobalt, or have elements heavier than uranium which are even more effective for generating a truly monstrous field.

I did some preliminary calculations suggesting that an earth sized planet is far below the minimum size for an effective field but suggesting we might be the exception rather than the rule.

in fact aliens might ignore us because their astronomers are concentrating on systems with large rocky planets with a certain key metallic signature in the stars spectrum.

Re. Pi

Probnably better off using the PCBs from relatively recent (eg Note 4) smartphones with cracked screens, they are quite a bit faster than a Pi 3 for the same or less power usage and can be substantially improved with a little heatsinking.

I tested this with an S4 Mini and S3 Neo, both power up with the screen unplugged and USB available so there shouldn't be any problems here.

Irony: that "old" smartphone is actually 24* as powerful than those early Pentium 133 machines and added bonus is that its onboard Wifi/Bluetooth can often be repurposed for intra-node communications.

Lack of range is not an issue and transmit power can be turned right down so the chips don't overheat.

Amazing new algorithm makes fusion power slightly less incredibly inefficient

Conundrum1885

Re. Hmm...

Patent pending:

"Method of generating fusion energy by utilizing closed timelike curves to control plasma instability"

Essentially a souped up version of active feedback.

If you know where and when the plasma is going to buckle then applying the counterforce before the event will prevent it occuring in the first place.

The interesting thing is that time travel in the sense of a closed system is actually consistent with thermodynamics, if the information never leaves that system.

So a time machine in an impermeable box is feasible, and quantum computers can be viewed as a time machine that sends back its "answer" to a short time after switch-on.

Re. EUV

Interesting to note that we've gotten this far without EUV kit, 7nm is still pretty impressive.

The number of machine learning steps needed to make a chip work at all with such small features is 4 or more generations, essentially we have long since (around 2002) lost the ability to know exactly why a given transistor goes where, or why a chip that works fine at 4.2 GHz fails either side of this.

I did recall that some newer chips are pre-screened at the factory using X-rays, presumably this is for aerospace and .mil applications where reliability has to be absolute.

Also recall that the newest memory is only ever powered up after all the chips have been assembled into a stack (see earlier) and often the yield can be as low as 60%.

That 256GB uSD has monstrous overprovisioning equal to 320GB, in fact 320GB isn't even state of the art now and getting the yields up was the reason 200GB and 256GB were spaced by five months.

Ah Hell NO!

The worst thing is that thanks to this my volume of SPAM just went up two orders of magnitude.

Yes airgaps work. So does Epoxy in the USB, headphone and unused keyboard ports, seems some folks worked out how to use an SDR and powerful ultra-precise narrow band radio transmitter to fake out the signals PC is expecting from a PS2 keyboard *without touching the machine" thus negating airgaps.

Devised a defence though, put 560 ohm resistor between data/clk lines and GND, then epoxy over that.

I did work out that modulating the CPU clock can send data at about 100bps, in fact you can get better than that by using mutilevel data ie 0,1,2,3 being different CPU core usage patterns and thus more/less clock speed.

The VGA hack has been known since way back, similar principles to the "Evil Maid Attack" where someone plugs in a device into a live machine's exposed HDMI or VGA port that then runs attack tools to pwn the host, in less than 24 seconds.

Fix here is problematic, I resorted to cutting the ID lines and modwire in a written e2prom chip with the most common monitors pre-coded via keyboard shortcuts seems to work so no data can be infiltrated in this way.

PACK YOUR BAGS! Boffins spot Earth-size planet most likeliest yet to harbor alien life

There seems to be a correlation between large planets in close orbits, and fewer flares.

My estimates suggest that in fact the presence of interacting gravitational and magnetic fields causes the solar turbulence to be different and results in lots of small less harmful flares sort of like how the Moon prevents serious seismic activity.

Also a sufficiently powerful geomagnetic field might make all the difference, the field from a "Super-Earth" might *just* be enough to permit complex life.

I did wonder about whether intelligence might have evolved there, 200MYa Earth was very different so the possibility of complex non-mammalian life is feasible.

They really might be small, grey and smart with chromatophores to give them natural cloaking abilities, large eyes adapted to the increased infrared and all sorts of other features.

Perhaps Betty and Barney Hill got it wrong, the "Grey" homeworld is in fact a planet much like this one.

Re. funding

Same here. I have some good ideas, but am unable to test due to lack of parts and funding.

Interestingly the problem is more that as the chips become more complicated (eg TPUs) the power consumption goes up exponentially despite reductions to 11nm and other such changes designed to mitigate the laws of physics.

Perhaps what is needed is a simpler chip, sure use 28nm as its a well established process but design the processors so that there are a massive 3-D array of hyper-connected chips with a quantum clock that synchronizes the entire network (eg optics) so each APU is indeed working in synchrony with the others.

If this is not done the cemi field analog can't form, this was in fact tested here and it works even on a 2009 vintage laptop with DDR3 RAM under specific conditions of temperature and supply voltage with the noise from the CPU regulator under low battery power being the missing link.

Evidently the problem is that typical RAM is designed not to interfere with itself in this way so the only way to get anything to happen is overclock it well past the point where the machine normally fails to boot, then cool the RAM down until machine starts up reliably.

Re. price

There was I thinking that £350 for a used GTX1080 card was cheap.

Seems that folks using these for Bitcoin mining realized early on that custom hardware was better, however the cards themselves have many other uses such as medical imaging, machine learning, data analysis, password bruteforcing, etc.

Serious gamers moved on a long time ago but for certain applications (eg machine learning) an array of cheap used cards on budget boards (eg quad core AM3+) will still do more work than one £xpen$ive card when suitably retrofitted with better cooling and updated thermal management such as heat pipes just for the RAM not to mention the latest software custom designed to squeeze every last IOPS out of the overclocked GPUs.

I once did this to my not-2-day-old RS480 and got about a 11% performance boost with no overheating.

Some other folks are leveraging used laptop boards with on-chip GPUs as they are quite compact but this approach is significantly more complicated due to limitations in clock speeds with a laptop.

Even replacing the base clock does not help here as the limit is in the interconnects.

Re. recycling

Irony: the "cheap" electronic tat is actually easier to recycle using machines.

On the other hand, there will still be a market for some human labour eg dismantling the equipment to feed PCBs into the deconstructor (tm) so the individual parts can be tested and reused.

For example many older pre-monolith TVs are remarkably high in useful materials such as white LEDs and the expensive rare earths in the speakers, high precision glass, plastics etc.

Even the panels can be recycled if intact and there is a market for "70% recycled" TVs with OLED backlights or some other innovation.

Just spent a morning fixing one, had two failed LEDs in the panel but its possible to replace them if you have a box of salvaged diodes in this case rescued from a broken outdoor security light.

Probably better than the original and should last a comparable amount of time and for my purposes a new panel would be a complete waste,

Re. High Frequency Trading

Actually feasible, the big problem has been wiping the memory.

I have since determined that an invert + zero ie writing the logical opposite to the memory directly to force all cells to "11" then write all zeros is the most efficient way to erase flash memory for reuse in the field.

Its gentler on the chips and if any fail this test then they get stripped down and recycled.

Plus all the firmware updates can be added so that annoying b0rked sensor is fixed, from what I have learned the new iris sensor is similar but using better software and a dual rather than single colour sensor plus fluid lens to increase its focal depth.

I also found evidence that many "new" SSDs are in fact repaired or reprogrammed units that failed initial tests at the factory, the bad chip replaced and sometimes even just the controller is upgraded with 2013 chips being upcycled and reused.

The giveaway is that the speed will be much lower than a 2G V-NAND.

Pauli Effect

Had a few cases of "talented" people breaking stuff, mostly of the "OMG you blew up my broken power supply with your flaky MB, get me a new one right now!" then "Actually thanks, the replacement solved my PC problems which have been going on for months, k"

Recently had a spate of motherboard and HDD failures which I traced back to glitchy power.

Somehow despite the units being behind 2 (!) layers of surge protectors the mere act of turning off power was enough to eventually corrupt the CMOS and trigger a failure.

There is an argument that MB CMOS batteries are prone to failure and even just knocking the PC can be enough to break them.

I had a machine which somehow lost its CMOS settings when doing a routine test, despite the battery being at 0.01V it somehow managed to hold its memory because the board did not work after that.

Pretty sure that they have sneaky software that detects a date/time change in any files past 2006 because thats about the only thing which changed when battery was replaced.

The act of metering it was evidently enough to wipe everything so its going to be very hard to fix.

Also had SSDs kill the attached machine, seems that people end up replacing hardware because they swapped HDD for SSD then laptop boots fine once or twice and never again when cold started.

Pretty sure this qualifies as "strangest fail ever" as the SSD tests fine in a USB and works in my laptop

perfectly well but going to send it back anyway because its firmware won't update at all.

I am going to check the screen memory because this is a well known problem with 10 on some chipsets and it wipes out a crucial byte in that 8 pin memory used to ID the panel.

Re. entropic gravity

A while ago I suggested that perhaps we should be looking not at any one hypothesis but the zones at which they interact?

eg where entropic gravity and MiHsC/MOND are similar.

LUX came up blank, ADMX was inconclusive.

There are a lot of valid arguments for candidate particles, axions are speculative but marginally plausible however it might take decades to detect them.

It later turned out that the diurnal radiation anomaly might have been specific to one type of tube and temperature was not compensated for adequately also atmospheric pressure might have been a factor due to interactions with the radiation.

Ask Radu Motisan about this, he's got about 3 years or more of data and its still being analyzed now.

The sensors are identical to mine however they are noticeably more sensitive to said effects if run above 400V so this is well worth investigating.

Re: doubling the response time

(soapbox)

If someone does this, its probably going to rival a Hollywood blockbuster as "Most downloaded .torrent"

Also why in hell are we as a society allowing a few people to decide something this important? This is the same Government that brought us classified patents where inventors end up living in abject poverty because they have to start from scratch each time.

IP laws are a total mess

I actually need to check something in one of those old dusty .zip files, because it proves priority of an invention.

Any ideas? Pretty sure that the passphrase was something to do with a film but which one?

Large Hadron Collider turns up five new particles

Technically

All that "missing" antimatter might actually be hiding in plain sight.

Also a positron is not the *exact* equivalent of an electron but pretty close, I've since extended my hypothesis to suggest that due to the gravitational interactions conservation of energy *requires* antimatter to have less gravity than matter (-2.993%) and the lack of anti-stars is proof positive.

Its also possible that ball lightning could as conjectured by D ASHBY indeed be a form of metastable positronium formed high up in Cu-Ni clouds at the edge of space inside the red sprites and/or blue jets, making its way down the ionized plasma channel and appearing out of nowhere as well as being able to appear inside a building or aircraft due to the positronium behaving as a quantum macro-object with a high Rydberg number.

It could also be that nearly all UFO sightings are actually forms of this, it can appear as a shiny disk as well depending on viewing angle and other effects.

I've photographed a possible BL once and it did seem to hover on several frames, estimated lifetime of maybe 0.5 seconds but hard to make out as it was taken on an old Canon D500 out of the late Cambrian era.
