Is this why Oakleys used to say "Thermonuclear protection" ?
We need to know, a choice between knackered data and "theoretical" risk isnt much of a choice is it?
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.
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.
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.
These will just be securely wiped, and then reinstalled with custom firmware (abandoned = open source) and given to the needy? 36000 phones for the poor would go a long way.
I had this idea a while back as M$ did the same with Atom netbooks which still run Lubuntu perfectly well.
Methinks that GTX1080Ti would be better for playing Crysis.
Also how much faster are these specialized cards?
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.
see this, someone else's project.
Was reference to Logan St Clare.
I think this could work, at least for medical imaging and a compact MRI-like device that could image a sample several feet away with a superconducting magnet cooled with a closed cryocooler.
If higher temperature materials are feasible then a handheld "remote control" could actually scan for anomalies just like a real tricorder.
Open letter at the moment about AI weapons.
But yes I think there needs to be a discussion about laws prohibiting certain types of "killer robots" certainly incorporating a version of Asimovs "Three Laws" from the get-go.
A robot should have the right to refuse a human order if in its own judgement the action would result in substantial loss of life and violate international law.
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.
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.
Has anyone else figured out creative uses for off-the-shelf electronics?
Current projects include:
Hacking BT headsets to turn them into UARTs
Modifying infrared thermometers, scales etc to add the missing USB output
Hacking TVs to enable features such as selective backlight (ie stealth mode) and
retrofitting LEDs to CCFL models, RGB backlight for high contrast/3D mode.
Capacity testing/reconditioning of batteries using old PS4 hard disks as a dummy load
add your project(s) here
Yup, was aware of 4.0
The reason I think they used NFC is that most older phones do not work with BT tiles, their intended market seems to be holidaymakers who often use (in many cases) burner phones so if they get damaged/lost then its inconvenient but not catastrophic.
We had this discussion at the Hackathon last year!
Peak for me, I have no idea why.
Maybe due to some circadian clock issue, it is hard to know.
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.
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.
Certainly fits the data, though the catch is no black holes smaller than maybe 3.8M0 have been seen.
Would the hypothesis work with micro-black holes as you might see at an advanced state of decay ie maybe a Jupiter's mass or less?
Maybe. I did wonder if this might get around interconnect issues, provide chip power using 13.56 MHZ around the edge on each chip then offset chips similar to how microsd are made. Advantage is a bad shorted chip can simply be ignored not doom the whole tsv stack!
How would this happen?
My theory: motherboards are removed, cloned and wiped then sold online via the lowest bidder months later.Meanwhile barred boards are purchased online, tested and refitted.
Plausible deniability, and PROFIT!!!!
Think about this for a minute: it takes less than 10 minutes per phone and forensics works both ways.
Tools are available to clone phones and this has to be done anyway, so why give back the evidence that might be used later in court?
You really think that all the locked boards online are wasted? Hell NO!
"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.
Just a thought, H3 might actually be the missing link here.
Changed USB port on an S3 Neo, though it charges the data pins do not work.
One thing I would like to see is genuine batteries available for older devices as these are getting hard if not impossible to find.
Is 9.6 miles across, travelling at 47,308 km/h.
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.
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.
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.
Life will find a way. (Jeff Goldblum)
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.
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.
"My logic is undeniable..."
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.
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,
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.
Or my favourite, a system that one day just stopped working.
Found evidence of mouse infestation, including possible urine traces on MB and cables after we went "Full CSI" on the machine. Got replaced and mice dealt with sternly.
Ended up using hacked traps with a hair trigger, that would set them off if we used an air duster on them from 5 feet away.
Guess what, leaving laptop in bag outside, in the rain on a motorbike = bad keyboard in short order.
You can guesstimate the amount of pollution in atmosphere by timing how long a new keyboard lasts before bad keys show up, in some areas this is a six month MTBF.
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.
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.
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?
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.
Apparently all the Intel chips made since the P2 *which includes Celeron* have CPUID, but its turned off.
Or so they say.......... (X-files theme)
I did suggest way back when that it is possible using a timing attack to determine which CPU a piece of code is running on, by measuring things like instruction unitialised value bias shifts and decay time on unrefreshed memory, this is basically also how data is exfiltrated from "erased" SSDs and HDDs.
There's a few kB unused which is kept refreshed but no data is written to it, that caches the microcode during bootup but is usually not written to after that, so this is entirely feasible.
Similar to how some older machines would let you access the SMBus or SPD chips as they only ever normally get read during initial boot-up. Even found a few laptops and netbooks (eg PCG-61611) that let you write and read to them which is handy when you have flaky RAM that needs to be underclocked.
Obviously replacing the chips with a slightly larger (eg 256KB) re-marked custom part would let you compromise a machine using buffer overflow on each and every startup, even flashing a custom rooted BIOS that fakes out the password routine so the target thinks the machine is secure.
Some webcams in laptop screens have 512KB of memory in them and this stores things like the offset
tables for the CMOS sensor so that the image is clear. Obviously this would also be trivial to replace.
Found something about AOA150 speaker being too close to the HDD.
What if: the voltage from the DVD drive motor during spindown was somehow causing glitching in the voltages going to other pins?
I have suspected this since 2009, ever since my mostly new x520 started throwing "Disk Read Errors" and refusing to let me copy files from the stock 500GB to a new drive.
Every single machine that drive was installed in later failed inexplicably, even after a zerofill (twice!) and other tests which passed SMART and other attributes the drive never reliably held a Windows install.
This machine also had intermittent problems from the start, later found that the Core 2 Duo only had 3MB instead of 4MB cache and also refused to let me use more than 4GB RAM.
Also lost a 1TB drive and another 500GB since, all failed with the same symptom pattern and machines they were installed in also failed apart from the c650 which seems (so far) to be holding.
The drive which is in there is also slowly deteriorating and this time it shows actual bad sectors yet the
SMART says everything is fine and it is losing performance. (yes I backed it up!!)
Lost my external 3TB hard drive but this is just a power supply issue and traced one problem back to a bad USB3 cable.
It wasn't the infamous x32 memory limit as the machine simply wouldn't turn on, also had issues with external drives inexplicably failing, two bad pendrives (both same controller) and bad SD cards.
Trouble is that as mentioned earlier every drive has been "contaminated" with this thing and I can't trust a single backup made since.
Latest casualty was my HP 3000 netbook which failed after upgrading the stock 500GB to an SSD at which point it failed to boot about 2 days later.
Apparent BIOS issue here as its the same chip (Winbond 25x160) and in fact the machines that failed all had near identical parts. Acer Extensa 5220 (1MB), AOA110, AOA150, PCG61611, 650C but my desktop also has an earlier version of the same BIOS albeit on a 44 pin chip.
Can someone skilled in forensics please have a look at this before I hand over the drives and be done with it? Thanks!
It works OK on this machine apart from one very annoying whining message about athbtx all the time.
Still can't get my PIC programmer working but this is more that the software sucked even on Windows XP.
Little hint: Genuine Arduino and FTDI work fine, fake do not.
I've been known to use Sellotape and fine tweezers to extract SIM cards from phones when some eejit tried putting the wrong card in.
Amazingly it worked!
Also: repairing printers, reseating memory chips, fixing printer cartridges.. it is really really handy.
Not to mention Sellotape + Russian zrzsg plastic graphite = homemade graphene, this won a certain
Prof. Geim a Nobel back in the day!
It also works well as an EL dielectric for a while at least, and is just the thing (tm) for insulating PCBs when trying to install tiny modwires or rework tracks for some hack or other.
Kaptop tape is even better and has been even used in production for this very purpose.
Hi, just a thought but I wonder if this information should be sent to the eejits who insist that the Moon Landings were faked.
I also noticed that an idea suggested by the film "Fantastic Four" ie movable shields which only rotate and reversibly lock in place when needed. Sort of like a camera iris but 3-D and precision engineered.
No doubt some sort of MagLev setup would work here and add a measure of safety with the option for manual activation if the automated systems break down via a hand crank or 10.
Did some work on HTSC shielding a while back but its not really feasible except for massive spacecraft and only for small areas such as computer centres and "Safe Rooms".
It can actually make things worse for the rest of the spacecraft as the particles have to go somewhere, on the other hand they could be captured and used to supercharge the "Conundrum Drive".
Did anyone do the calculations for an FRB being responsible in some fashion for the Wow! signal?
My thinking here is that there could be some combination of natural events eg narrow beam of light hitting a cloud of hydrogen causing a brief spike at 1.42 GHz ?
This is an alternate hypothesis to the one suggested about natural maser action in molecular hydrogen from those two comets, and also could account (indirectly) for the relatively narrow band and lack of repeatability.
As it happens I might be able to test this with a fluorescent tube starter and small laser: any old DVD writer would work and the IR laser can be modified to focus on the empty area at the end of the tube.
Alcatel Onetouch POP2 45, defective out of the box.
Had endless trouble with popups, excessive bandwidth use etc, even put Kaspersky on it but all that did is slow the phone down even more.
This particular unit seemed to have fakeflash as well, as it only let you use 1GB of the internal memory
yet it had "2.97GB free".. yeah right.
LCD later failed for good measure so I gave it up as a lost cause.
Hint: if anyone wants it for forensics purposes and has a somewhat working screen unit with good cable feel free to send it in my general direction!
When merely opening your browser, typing in a social networking site and because some random hacker or malicious person has diverted a link you now have EP on your profile, you and everyone else who goes on FB is guilty of an offense.
SO why the hell is FB not blocked by ISPs until they fix it?
Some pendrives use a green LED, some use blue.
Guess what happens when you shine a (blue) laser pointer at a green or red LED, while the pendrive is writing? Google "Forrest Mimms"
(Hint: Don't do this unless you want to ruin the thing, it injects strange voltages back into the IC causing write instability, slowdowns and on some cheaper units can actually burn it out, permanently! Seems this is how they are sometimes programmed at the factory with the bootloader!)
Has anyone here run into this?
Seems that at US borders, DHS are asking for people's social network passwords despite this being (a) violation of FB's T&C, and (b) unconstitutional.
Is this sort of behavior unacceptable, and under what circumstances is handing over anything (eg phone, keys to car, DNA test results, etc) appropriate in order to prevent a visit from the Police, etc?
There was a case a year or more ago where a company (possibly on the Fortune 500) did this and got tarred and feathered for this. IIRC it cost them a small fortune and eventually they did withdraw the clause in question grudgingly.
