Navigating without GPS is one thing – so let's jam it and see what happens to our warship

Conundrum1885

Jusrt wait

Until there is a big solar storm knocking out GPS at the same time as a magnetic field anomaly.

One day soon the poles WILL flip and for a brief time navigation will be problematic.

Its been suggested that something very much like this might have done for MH370.

The working hypothesis is that there happened to be a brief magnetic spike in the area which has

in fact been reported before by both shipping and aviation.

By sheer coincidence one of the passengers had a faulty phone that "hooted" on the GPS L1 and L2

bands and this unfortunately coincided with the magnetic anomaly causing the plane to fly in effective

circles until it ran out of fuel.

Normal communcations being knocked out may well have been a short in the wiring: likely the

transmit side went bad or off frequency but reception was still possible.

Similar issues have been reported before with older equipment more susceptible to certain types of

faults.

TV brickage? Part Deux

Incidentally my Sony Bravia from the Early Myspace Era (tm) is still going but ran into the MHEG5 issue.

Its only really a problem if I use free-to-air but having one HDMI limits my options somewhat.

Now if there were a way to make say a Bluray player output VGA natively but still report that its

connected to HDCP enabled device in another room that isn't even turned on.. hehehe.

A RPi can output composite video so the function on older players enabling compatibility with non-HDTVs

might still be present though not used.

The policy of truth: As ransomware claims rise, what's a cyber insurer to do?

Conundrum1885

Something intriguing

I've found that a lot of external HDDs and other devices are counterfeit and/or fake capacity so the capability to embed date/time or usage triggered malware also exists.

There have been cases where the entry point of a specific piece of ransomware or malware has not been found despite extensive efforts.

Is it worth looking in more esoteric places like the monitor, optical drives and USB cables?

To write malware that hides in the SPD chip on DDR4 RAM is another not so well known method and as its quite hard to write in W10 etc it wouldn't be much of a stretch to implant something nasty that only dumps its payload when it "sees" a specific setup like a server grade CPU or more than n system drives.

So your average home user won't even know its there.

Also heard of more recent malware that reflashes the BIOS with its current settings intact so unless someone goes to alter it they won't know that its actually been compromised, or a combination of the two that writes persistent code to any programmable chip.

Re: Incidentally

Well, he used a computer to order the device (charge 1), used "unauthorized access" to get into the lab and do damage (charge 2) and then incite others to do the same via video blog (charge 3)

At the very least they could also add a charge of money laundering as he apparently used crypto-currency obtained by deception to order the device (charge 4) and failed to register as a currency exchange (charges 5, 6, 7)

Incidentally

Its been suggested that part of the problem is that cases never get to court in the first place as they are tried under something else.

Case in point, car thieves using a computer and SDR to break into and then steal expensive designer vehicles should logically lead to

a CMA conviction but I haven't seen any evidence of one.

Same with the infamous case recently of a student using a USBKiller to damage school property.

In the US the culprit got 10 years in Fed for this, but the one in the UK was just cautioned despite being caught red handed with it.

Boffins improve on tech that extracts DC power from ambient Wi-Fi

Conundrum1885

Re. Harvester

Yes, this might indeed be a problem.

The fix would be just running the DC-DC when the capacitor actually gets low.

A smoke alarm battery powered by WiFi would be useful, however the reason for using an alkaline is that when actually sounding the peak

current can get surprisingly high (amps)

Incidentally does anyone know how those WiFi boosting bulbs work?

It looks like they receive one channel and then retransmit on another, but how does it compensate for latency and for that matter multipath

interference?

Would make more sense to receive on 2.4 and transmit at 5.2 so devices can lock on to the "better" signal thus freeing up the lower bands.

Re: Re. Update

Are you absolutely sure?

Look at what happened with 20H2, that somehow got onto secure systems despite in many cases admins actually stopping all updates. It got through and caused complete mayhem.

Best guess is that other machines were hosting the update(s) as is enabled by design which bypassed the usual blocks so someone bringing in a laptop with it installed was all it took.

It wouldn't be much of a stretch to block specific file content, and as I mentioned very hard to undo.

Just to give folks here an idea of the lengths certain authorities go to, it was possible for a piece of malware to get into the uEFI BIOS on a system here, and completely block access to an entire drive even on a clean booted system having worked perfectly the day before.

Even cloning the drive didn't help as none of the usual programs would work: the error message suggested a sector alignment issue but cloning everything manually to an identical drive also didn't work.

The only thing which made any difference was using a standalone box which copied everything except that specific multi-part .ZIP archive suggesting it was the underlying cause of the problem.

Re. Update

I have it on good authority that Microsoft, Google AND Apple are about to block common Wallet apps via mandatory firmware update.

Ignore it at your peril, because sometime soon you won't be able to run any of them on common devices or even access the stored files.

The problem here is that as there's often no way to downgrade you are stuck, as many app developers found out to their cost.

Something interesting

I once looked into building a "force field" for another project.

Actually had some success with a short range deflector beam, but the problem is energy usage.

It might be possible to build something about the size of a phone charger pack that detects muzzle flash and

*rapidly* dumps just enough energy into the specially shaped coil to deflect a projectile if fired from a long enough range.

We are talking room temperature superconductors here so not exactly possible on a large scale yet, but it would also

be adequate for other tasks like deflecting cosmic radiation.

Now for the legal issues.

In principle, a personal force field would come under "defense" but as its not capable of actually doing damage under most

conditions the DoD would likely be most interested.

Re: But does this mean I can have my flying car?

Working on it.

The main snag is that I did find a way to repel off a surface similar to a ground effect but using ions, in a helium atmosphere though the main problem is that the required very thin uniform HOPG isn't easy to make and it still needs >10KV and an alpha emitting radioisotope or £xp£n$ive hard to obtain deep UV LEDs to generate enough of an ion current.

Fusing smaller pieces together under methane at high pressure *might* work if I used a laser or DBD but theproblem is getting sufficiently uniform starting material in the first place.

Its said that when they go through a keyhole BL can explode with little or no warning, or appear to fizzle out then reappear somewhere else.

Something strange

I once saw an "odd" sparkling object off centre during a very intense thunderstorm.

From the clear footage it seemed to have a cloaking device that was being affected by the lightning, as it was clearly visible with a plasma "tether"

Unfortunately its long gone now but it got submitted for analysis with something called "The Nexus Project" thats all I know.

Might have been regular BL but either the lightning flashes messed with my brain or something strange happened that evening.

Now what is intriguing, upon recollection of the events of that evening my clock in the car didn't line up with actual time

but thought nothing of it as the battery wasn't exactly great anyway and had problems with that car if memory serves.

Re: Another test of General Relativity

I have a standing bet with several folks that antimatter will turn out to have different gravitational acceleration to matter.

Whether this extends to the point that it could be the key to interstellar travel is as yet untested, however even a tiny change under certain conditions may permit an Alcubierre drive to function with accessible power requirements.

I've also often wondered if an isotope like 22Na might be key to such a drive, and in fact looking for its decay products in the form of characteristic gamma and X-rays be a sign that one is in use.

The tail might have been retained but as with hominidae it got absorbed much like the appendix.

In fact its said that there might have been more than one intelligent species here on Earth, as mammals may have slowly expanded

to fill niches left by larger predatory saurians as the latter died off.

Cold blooded is actually not entirely accurate as some dinosaur fossils show evidence of a trend towards higher body temperatures

Re. EHT

AFAIK they had to get special permission from Sony to use CFW on them and hand back key components so they could never again be used as a

Also recall that the PS4 can be used in this way though required getting dev kits ($$$$) and cloning the Flash chip(s) from one with Sony's permission then signing it with the root key and console key etc.

Re: Not just me then.

Like that time I was testing one of my "creations", a dual ignition coil beast with Epoxy insulators and TV flyback wire spark spewing gadget running on a chunky 12V SLA that I was certain qualified as a weapon of mass destruction when it wasn't blowing 2N3055's like popcorn and the occasional 555 timer.

Possible superconductor discovery

Hi, now I don't want to get people's hopes up but..

It looks like my research is potentially going somewhere.

Is anyone here familiar with IISC and their claimed gold/silver nanoparticle material?

Seems they weren't wrong after all.

I've now established not only a plausible theory for how a normally good conductor can

superconduct well above 273.15K but that its possible to easily examine materials

in bulk which up until now was deemed impossible.

Its actually quite simple really, looking at the basic physics of how OLED panels work

gave me the inspiration and then it was just a matter of finding the right combination

of materials.

Turns out that multiple processes are needed but the starting materials only need to

be moderately pure and not contain iron, nickel etc.

Ir is indeed the secret and I am in the process of making a larger sample.

Its been suggested by someone who cranked the math that this sort of density (ie a fully grown adult shrunk to 6.2cm high) would be in the realms of a neutron star but in fact it looks like they'd be approximately 26.22 times the density of uranium.

In fact no element on the periodic table has anywhere close to this.

Maybe if there were undiscovered elements somewhere on the Island of Stability ie doubly magic 121-124 if the quantum spin calculations are correct for nested proton and neutron shells but again this is probably beyone most people's abilities to calculate.

Conundrum1885

Re. Bad News?

Actually lasers can be used in a different way.

In this case messing with the molecular configuration during ALD may work.

I found out a while back that blue lasers (440-460nm) can be used to "tickle" the Sr atoms in BSCCO

and am in the process of making a test pellet with the aim to make the 2223 variant with high Tc.

The trick is to use a very thin layer on special glass and "nuke" it from the transparent side.

In fact sandwiching pre-crushed and part calcined Mott insulator between two pieces of glass and then

doing the laser step under flowing O2 may work.

The formula has to be absolutely correct and even a trace of ferrous metals may foul things up.

Posting this on here so folks can replicate it as and when the paper gets released, by following my

train of thought.
