Russia spoofed AIS data to fake British warship's course days before Crimea guns showdown

John Jennings Bronze badge

Ummmm

Think you missed a few there.....

Samoa

Cuba (Multiple times)

Panama (multiple times)

Honduas

Haiti (multiple times)

South Korea

Vietnam

Russia

Iraq

etc.

(assuming you are including unsuccessful interventions and setting up failed states as well)

According to Wikki (the dubious font of all knowlege), The US has actually been directly (overt or Covert) involved in 81 regime changes. That does include some countries multiple times. Tripoli/Lybia being the first instance.

Re: Just a FYI

There was an (albeit informal) agreement under Regan that there would be no push of NATO further East after East Germany and Turkey. Russia was weak with the collapse of the CCCP and Warsaw pact. It isnt so today. We broke that with the inclusion of the Baltic states.

Why would Russia (or anyone else) take agreements with Western nations on faith again? Indeed, faith agreements or written ones (see Iran and the unilateral withdrawal from those agreements at a political whim by the West)

The one thing that ticks off ALL russian strategy is encirclement. Its why they pushed back on Crimea. When we caused the Ukranian revolt (and make no mistake, we caused it and installed our boys - right wing (nuts) or not) under Clinton, then Obama, we threw out that agreement.

We may yet reap what we sow.

Re: To sadly turn this political

Actually, we buzzed the Russian carrier when it was in the Channel. You didnt hear the half of it.

We 'shadowed' it for most of its journey to Syria. We sent a Duncan and Richmond on the way down and a frigate and typhoons as it came back - and judging by the footage on the BBC - we 'escorted' it quite closely.

Tampering with AIS is common for the military - all sides have always done it.

Remember that the incident where the US frigate was rammed a bulk carrier in the China Sea? It (the frigate) had its AIS disabled at the time (intentionally - military ships have a switch on the bridge for obvious reasons - illegal or not)

https://www.maritime-executive.com/article/fitzgerald-made-20-knots-through-traffic-without-ais

As to spoofing - The Iranians managed to capture a Drone with a simmilar technique years ago. The Pentagon just turn the whole thing off in an area when they want to:

perfect example of using one thing - and unintended consequences

At the moment, I cant think of an effective countermeasure.

These camera modules are generally third party and (fairly) standardised COTS. The onboard processing is 'correct' for its context. It could well prove a major refactor to avoid this attack vector. I wonder if any self driving incidents to date could be associated with (even inadvertent) for of image destabilisation?

UK spends £36m on 18 little 'bullet-proof' boats to protect Royal Navy assets

John Jennings Bronze badge

Re: Well tried and comprehensively already field tested .....

Most fast coastal boats drop their guns low when not in use.

It makes a massive difference to top speed in these smaller boats - its not so much aerodynamics but centre of gravity - low down improves speed, manoeuvrability and seakeeping.

having travelled at 25 knots in a swell in a similar sized boat - a dude moving to the bow forces a trim change. You need the weight low. When its travelling fast, noone is going to see a gun anyway- unless in active persuit.

ICE - still the way to go

My old 1969 triumph is more green than any leccey car today.

Repairable

Not particular efficient, but in reality, the green cost was sunk just after I was born. Fuel is the least of the cost in the total life of the car. 35mpg inst that bad for cool factors

Little plastic - mostly leather and wood trim and steel. Any of it can be replaced and much of it has (it is a triumph, afteral - so (at least 2 sets of sills, bottom doorskins, floor etc)

The thing its missing for today is a way to absorb NOx and particulates

It also needs more pampering than a modern machine - thats part of the TCO.

Main difference is that none but me is going to f**k with it to reduce performance. Not VW, not Tesla (the company doesn't even exist any more). I can modify it as I choose - I fitted rear seatbelts and twin webber carbs 20 years ago- myself.

If we want to make the world greener - make things repairable - AND require the owner to take responsibility to maintain. There wont be so many cars on the road as today.

Space is hard, and this as a future model for LEO is perhaps ultimately the most efficient method for getting junk up there.

Australia probes app stores, politely suggests Apple and Google could try being nicer and more careful

John Jennings Bronze badge

The second recommendation is more important - and a potential sting in the tail

The idea that Google (or Apple) would develop an app - and not share the data gathered from it with other parts of their organization is a game changer - It wont happen unless the auzzies man up and mandate that through legislation.

I imagine that google and apple dont just gather the data on their apps (look at the permissions different functions demand to operate) - but they also collect all the data on individuals that they can scrape from the use of third parties apps as well. Amazon, for that matter, does exactly the same with their services too.

You are in possession of a file which corrupts the instance of evidence on your - or others cases (I assume that the application is networked)

John Jennings Bronze badge

I could see a use for this

As a life raft.

One of the problem with life rafts is that they can puncture - easily - the seams have also been know to rot out from UV damage in tropical cases.

A second is their wndage/boyancy - they need a sea drouge (usually hangs out below) and are un paddleable.

The kit could inflate (once) and have components inside to 'lock' open to make it semi-perminant.

It could also be 'Boaty' in shape - enableing oars or even sails.

It could be inflated by the same method as demonstrated - even flotation tanks.

Ah, you know what? Keep your crappy space station, we're gonna try to make our own, Russia tells world

John Jennings Bronze badge

Re: It does have a finite life

That is a bit harsh

Fact is that Russia kept the station going for more than a 13 years -when no other country could put anything up with people in it. (first time was the first shuttle accident, second with the end of that program)

The basic design was Russian - and the first modules were also - they have been up now for years, and proven themselves to work far and away beyond their design parameters.

Pretty much all of the ISS is operating this way - from batteries, solar panels, and internal spaces. Sure we could do better now - but - we have it now and have had it for 20 years.

Think of the thousands of thermal cycles alone that the aluminimum and glass has to go through...

The ISS has been one of the greatest achievements anyone has achieved. We should work for a replacement - but it should not be decommissioned before a replacement is actually in place.

It is unfortunately the case that current US paranoia has reached the point where joint efforts for its replacement will be pretty much limited to ESA and NASA. It makes it a lot less likely that either station will be as great as a proper collaboration could have been.

Lets hope the russions dont want their modules back - they provide a physical hub, one of the global life support/water recycling & half the docking ports.

'Imagine' if Virgin Galactic actually did sub-orbital tourism: Firm unveils new chrome job on SpaceShip III

John Jennings Bronze badge

His model isnt ultimately space tourism

Its launching microsats into LEO.

His ultimate model is likely more efficient than Elons method. White Knight II is his ticket - not the bauble he is launching currently - thats for show. He won a $45M contract from NASA last December.

It will become interesting

There isnt the market for 400 flights per year (per spaceport) for just jollies.

They have successfully launched 40 cubesats from the 747 - so have proved the technology. That research will give them an edge in miltech contracts - the real commercial target. The 747 cant launch as high as White knight II - but can carry more gross weight. I wouldnt be surprised if they have looked at Paul Allens plane for the same purpose. Its a lot easier, if a bit unimpressive to go hypersonic at 50,000 feet than from ground level...

Beijing's new privacy rules ban apps collecting unnecessary data, require free service without data slurps

John Jennings Bronze badge

Re: :) :(

China is interested in managing its citizens personal information with enterprises- and not permitting it in commercial contexts.

It is not interested in limiting its data collection - and this doesn't break that.

However, I think the approach is a bit naive - it would be stronger if the classifications are principles based, rather than the prescriptive methods suggested, For example - what is Facebook? Its a social media platform, its a chat platform, telephony and a sales and marketing tool. The context is king.

Further, the problem with a prescriptive list is that functionality could change over time. 20 years ago - we didnt have FB, The whole concept of Social Media is new. What new thing will arise, outside the controls (or shoehorned into an inappropriate area)?

I had a coupe of Trimphs from the 60's a few years back.

They rusted like hell (I used to keep old Volvo bonnets/hoods as cheap spares for welding new bits in from time to time - galvanised! - though I didnt know about Zinc poisoning....) All cars of the time did the same.

The machines were completely bullet proof mechanically, though. The basic engineering came from the 1940's-1950's and were simple to maintain, and I could actually get into mine (so could most other ppl if they knew how to bypass the locks!)

You dont need an atomic clock on an LEO positioning satellite. Synchronisation could be done from base stations - this has been done before as a backup to galleleo as its clocks went squiffy a couple of years back in 10 of the first 18 birds.

could have some practical allications sooner, rather than later

imagine making tiny ICs in multiple layers that fold into themselves. potentially make circuit boards that self fold into a grain to reduce distances between contacts.

it could even perhaps interleave as necessary with thermal conductors - to get heat out from between the layers.

It looks like they can make the hinge with an accuracy of a few atoms.

Perhaps this is achieved in another way already - IC design is a black art to me, tbh.

Re: The military industrial complex

Gunboat diplomacy was practically invented in Chiina last time (the Opium Wars) - it wont be again. China would not permit it - they have long memories - and the US couldnt do it. Sure - they might be able to flatten china (given enough provication) - BUT - the cost is too high for that now. The US pacific fleet cant/wouldnt go within 100 miles of the Chineese uncontested waters. It will drag a coat round contested waters where it doesnt really matter.

Re: "The Internet inteprets censorship as damage

I dont think that this meshes well with the China states philosophy.

They will most likely ban it - at least as an open connection (there may be technical options, such as middle kingdom basestations or simillar).

Failing that, they would rather disable them than have them running open. Believe it.

They are not US state birds (as was suggested above). They are commercial - the US govt wouldnt intervene kinettically... At least, that is the calculation China would consider.

China was invaded before with trade and commercial interests. The Opium War was the last time - and this shapes Chinas thinking even today . That worked because China was divided and industruially primitvie compared to the great powers (and the US). I dont believe China would permit this again - and its strong enough to resist this time.

You have heard of the ford pinto?

That was in production, with a known fatal flaw (for the driver!) for 6 years, with the flaw known about in design (so 8 years total).

Cost to ford was ultimatelty aprox $5M in damages, recalls of 300K cars and a slap on the wrist.

In that case, they had known that a $1-$4 fix per unit would have avoided the issue - which they decided was not cost effective.

Do you really think liability will work for the fail fast culture? Fixes here cost a LOT more than 4 bucks.

Re: Belted up

sorry, Not correct. Hydrogen is, for its mass, one of the best elements at dissipating most radiation.

It is true that Polyethylene is effective - but too heavy for its structural properties. I understand that some work is being done on impregnating Aluminium (which usually makes it brittle but is used in current ships) with H2 to improve its absorption effects. Similarly the use of methane impregnated carbon fiber related materials in various epoxies/ceramics is being worked on.

Water wont slosh around in space. It is a solid if you want it to be. Indeed, it doesnt even have to be on the inside as it can also provide ablative properties.

further, the whole ship would not be shielded - just the bits with people in it - or a shield which can be turned to face potential bursts of cosmic radiation. Alternatively, some form of sleeping cocoon (or 'bag' with a few cms of water as a lining would go a long way.
