Sexist - do not think so. Are the ladies in question doing the dishes, washing the floor, putting out the laundry or doing anything else which the woman "should do" according to the "woman's place is in the kitchen astrophysical theory"?

No.

Hey, you, PHONE-FACE! Kickstarter in-car mobe mount will EMBED your phone into your MUG

Voland's right hand

Re: Quite Clever

Not so fast. The shield on top of the steering wheel airbag does not fly in your face. Stiff leather with reinforced backing is no different from a phone so if it went towards you you would have been cranialy modified too.

So in theory, it is possible to embed a display (if done correctly) into the steering wheel. Note - this is in theory. Big "in theory" here.

In practice (if done properly) it is one of the most stupid locations to do so. Your eye movement from road to mid-steering wheel and back is more than from road to pretty much anywhere on the dashboard. On top of it, the distance to there from your eyes is so different compared to the road (or the normal dash) that your eyes will have to refocus. This is one of the reasons (in addition to anti-glare) to put all readouts in a recessed dash and not in yer face. Constant refocus is actually even worse than distractions. It is a recipe for disaster.

This is one of the reasons nobody ever put any indicators there.

Now as far as attaching something to it with "spit" - well, that is beyond stupid. Even if the airbag deploys correctly, even if it does not fly in your face, it is just... stupid.

That's OK

Next time you see a GM refusenik ask him how much potatoes did he eat lately.

All potatoes are (albeit primitive) GM. They are a product of early work on radiation induced mutagenesis + cross-species hybridization of the resulting mutants in the 30-es and early post-war (both sides of the curtain). None of the currently cultivated varieties is something you can obtain via normal breeding and selection techniques. If you create something like this today it should require the same clearance for deployment as GM - it is a cross species hybrid with unknown properties.

US Marshals commit DIRTBOX INTRUSION on Americans, says report

Voland's right hand
Silver badge

Re: Pity...

If they had a warrant they could get the info from the phone company.

True. Also true that in USA due to the E911 legislation a phone can be triangulated on request by the mobile company down to 10s of meters or less (much better than most countries).

However, that services is not designed for pursuit. It presumes the target is not mobile and cannot be queried at high frequency so it is of little use if you are trying to catch someone, especially someone in a vehicle moving at 50mph in an urban environment (locating a mobile in hillbilly country is actually easier than doing so in down town New York). There is also a fairly limited rate at which the network can execute such queries especially in busy hours as they involve paging for that mobile repeatedly across a paging area.

So both the warrant and the fake cell triangulation using a MIM have their uses.

Now making a secret out of using fake cells is frankly stupid (it is a well known tech), but that is another matter. It just comes with the territory.

Re: Sounds like a job

Looking at that video it is more of a job for a knight of the mechanical variety. Unofrtunately, most weapons mounted on a standard issue police bot will be too weak to pierce through the several inches of blubber. Even a large bore shotgun is helpless when facing 20cm of fat.

If the whale has fermented enough already sticking a charge or two with a bot may be the only sensible solution as it may be too dangerous for a human to approach on the "belly side". Anything else aside, the fermentation produces not just methane so if this blows "in yer face" it may take a couple of fortnights and quite a lot of soap and rubbing to get rid of the stench.

EU Ryanair 'screen-scraping' case could affect biz models

Voland's right hand
Silver badge

Re: Genuinely stupid in the case of Ryanair

I find the BA prices always accurate on the comparison sites. I've used them a number of times this year alone ?

BA/Iberia is not being CheapSkate Air - they have multiple APIs including the legacy industry standard ones used by global booking systems. They do not make an issue from you having their current price so most price comparison sites get a realtime feed instead of screen-scraping. They do change them in realtime though - if you book BA or Iberia via Amex or Cason Corporate Travel you will see a warning that for these particular airlines the price is an estimate until ticketed.

Ditto for EasyJet - while they do not hook up to the normal global booking systems, they feed current price via APIs.

In either case there is _NO_ database backend except for a temporary and ephemeral storage of pricing data. The actual prices are produced by an algorithm so there is neither creative nor informative content in the database - it is purely a transfer and IPC medium.

It is only RyanAir which is making an issue out of it as if it is some super duper magic.

Genuinely stupid in the case of Ryanair

Ryanair operates a dynamic demand based pricing scheme (same as 99% of the airlines out there). All they need to do to kill any and every price comparison site is to increase the frequency of recomputation to the levels used by Iberia/BA (instantaneous recompute on ticket purchase) or (Sl)EasyJet - recompute based on number of views of a particular time/price segment.

From there on any information held by price comparison sites which do not have a contract to get a realtime feed is completely worthless (as is the case with BA/Iberia prices on price comparison sites).

However, instead of this O'Leary is being well... O'Leary. Changing of triggers and recomputation intervals in a dynamic pricing algorithm requires re-running the math models and sometimes doing some proper math work by a proper mathematician specializing in optimal control. That costs quite a lot of money and most airlines (including O'Leary) do not keep these on payroll - they actually contract people from universities to do that for them. So back on O'Leary being O'Leary - he is as usually cheapskating instead of paying someone to both improve his margins and solve this once and for all.

EU battles over 'anti-terrorist' passenger records slurper law

Voland's right hand
Silver badge

Re: Why only in Europe?

It is given if they require it already. The sole difference for the time being is overflights.

USA requires overflights to supply this information as well. This matters little as there is only a handful of flights which overfly USA airspace without landing there - flights to Cuba, Mexico, Belize, Haiti and the Dominican Republic.

I am not sure if Russia requires advanced passport info on overflights, if it does, avoiding that will make it quite interesting as it is quite expensive (our outright impossible without an extra refuel stop) to fly from Europe to China, Korea, Japan and the rest of the Far East without going through Russian airspace. Ditto for China.

Russia, China, etc (no idea about Cuba) definitely require passenger lists in advance for flights landing there.

Bendy, but hangs loose too: Lenovo Yoga Tablet 2 10-inch Android tab

Voland's right hand

It still justifies it in my book

Nexus has an extended "life expectancy" because of the third party (AOSP/Cyanogen) ROMs.

While there is some work on getting a working build for the Yoga it is neither very active, nor very successful.

That alone (the extended life option) gives the 9 a slight advantage. Not that I need one - for the time being the old Nexus 7 and Samsung 3 are more than sufficient in their "electronic pacifier" duties. If either one of them breaks I would go for the 9 (or something from Samsung which has a Cyanogen port) instead of a Yoga.

If she was not into smuggling them (AFAIK you no longer need to do that down there), then her decision is not surprising.

The cost of 99 Shiny Shiny is the start of the price bracket for an Audi or Beamer convertible. Looking at BMW UK site, series 2 starts at 29K. That is a grand total of only 58 Shiny Shiny. 99 Shiny Shiny will get you a nice spec series 4.

AC is not the driver

There's more than a few applications that push gigabit cable to the limit at a sustained rate

Linux and Mac network stack speeds:

UDP and other datagram protocols, single packet per RX/TX - 1.6Gbit per core

UDP and friends, multipacket rx/tx - 3GBit per core (Linux only, Mac does not have the relevant syscalls).

TCP without any offloads: 3-5Gbit per core

TCP with offloads - 6Gbits or thereabouts per core

Not sure what Windows state is, but it should be of the same order of magnitude.

So looking at these numbers, there is plenty of "need for speed" without having AC as an excuse.

This 125mph train is fitted with LASERS. Sadly no sharks, though

Voland's right hand
Silver badge

Good, but not good enough

A lot of what they are measuring can be picked up using a trivial black box style sensor package mandated to be attached to every train.

1. Missing clips - trivial image recognition.

2. Vibrations, etc - indicating the early stages of deformation in the rails - accelerometer and GPS.

3 ...

In fact, you can probably do most measurements using 200£ worth of off the shelf phone hardware with a couple of extra cameras. It will not replace the "proper" measuring train, but it will vastly improve the track safety. It will also mean that track is inspected every 5-10 minutes, on every train not once in a few months when the budget has allowed one of the few precious yellow trains to run a particular track. Actually - I take my words back - this should be enough for a lot low speed sidings and local lines which never get a seeing using the precious "yellow train" anyway.

Yeah, I know - while the technology to fit such realtime ongoing inspection to all engines is there already, because of the way railways are deregulated, making their owners fit it is nearly impossible without legislation.

Re: This doesn't make sense..

The Russians have managed to invent the "safe method" already. There heroin, morphine, cocaine and meth are yesterday's OAP drugs. The fun compound of the day are artificial cannabinoids, aka Spice.

Every time the regulatory bodies declare the current variety a control substance, it gets modified - a methyl group here, a hydroxyl there, some experimentation on the local drug addicts and voila here is the new legal high - perfectly legal for the next 6-9 months despite being as addictive as heroin. All that is needed is for the drug syndicates to employ a couple of PhD level organic synthesis professionals.

So no matter what the Atreides from the state police do, "The Spice Must Flow".

By the way, as far as the West is concerned it is a lose-lose situation. For the time being the Spice is confined to the borders of the old Soviet Union. It is not a matter of "if it will break out", it is a matter of "when".

Re: Not just windmill nutters

powerless GSM mast - Err.. BOLLOCKS.

As someone who has worked for 7 years designing GSM basestations, there is no such beast. If GSM mast is operational it is powered and has equipment attached to it. The only case where it is not powered is a DAS, but that is usually not used for masts, only for in-building antennas and very rarely urban deployments - f.e. multiple antennas on building edges..

Your average GSM mast has 1+ antennas, a basestation and for most of them a power unit which feeds the BTS and (in the case of microwave backhaul) the microwave P2P links which connect the basestation to the network. In addition to that the basestation cabinet and the power unit may also have environmental - heating and cooling (depending on the geographical location and the basestation model). All of these do generate sound across the spectrum. Usually (unless you are dealing with some really idiotic design) it is not much, but it is there.

Re: Not just windmill nutters

Queue letters coming in to the local council about headaches, sleepless nights, nausea,

Some people do get all of these. They are not however related to GSM, WiFi sensitivity or other psychobabble. The microwave intensities are simply not there for that. The root cause is different.

Plain and simple - these are people that have very low tolerance to vibrations and infrasound. Different people have different sensitivity, however every one is affected. As an experiment - you can put infrasound ~ 7Hz at >40 db in an office. Nobody will hear it (it is under the hearing threshold). It does affect every one, so by the end of the day people will have headaches, nausea and will be at each other's throats. Some will be violently sick too.

A turbine field will generate infrasound - it is the laws of physics - the collision of air waves deflecting off the blades off neighbouring turbines as well as lower harmonics generated from interference of higher frequency sounds from blades, etc. So will a lot of the power supplies for a lot of electronic equipment - they all generate ultrasound (from the power conversion part) and some generate infrasound as well as a result of intereference between higher frequency harmonics.

Usually the intensities are nowhere near 50 db :) This however does not mean that you may not run into someone with a "weak inner ear" who will be affected at lower intensity. It also does not mean that a particular turbine field has not been designed so badly that it resonates and some more sensitive people sick over time. Ditto for basestations and other electronic equipment.

Antares apocalypse: Orbital points finger at turbopump FAIL

Voland's right hand

Re: In this case, it's not the technology.

You missed one more. Pulling the dusty files out of the dark corner of the brain where they were confined after I got my Chemistry MSc and went to the dark side of IT: Many light metal alloys are not steel, they change with time and some of them quite a lot. Some of it is change in crystalline structure, some of it is oxidation, some of it is dark magic which noone understands :)

Most Al, Ti, Mg, etc alloys (as used in space tech from half a century ago) would have undergone a considerable change of mechanical properties over 50 years (not necessarily bad by the way, Al alloys generally become less fragile and more plastic with age). What would have been well within the tolerances 60 years ago, may not necessarily be usable today. If the pump has any elements made out of Titanium or Al alloys that would have been the prime suspect in my book.

IMHO - this is the biggest FAIL in the Orbital idea. It is not a rocket technology fail, not a control tech fail, not a refurb fail. It is a material sciences fail.

Re: Wrong Target?

To me, this seems analogous to instructing map-makers to leave out the shadier streets in a town.

It is not any different from instructing map makers to avoid putting that Minuteman or SS-18 launch site on the map. That is something they have been doing since the days when the first map was drawn (just in those days it used to be coastal batteries instead).

As far as going after the search sites, if the Minuteman site on the other side of the hill is not on the map the only people to know it is there are likely to be the neighbours and the "enemy". Everyone else will not have a clue that there are 16 nuclear warheads waiting to blow up someone on the other side of the globe.

Cutting down the audience to people who know it already is usually 99.99% good enough in terms of mitigating the effect of information which is the subject of "right to be forgotten". This is in fact the aim of the right to be forgotten directive - it is not to be forgotten by people who already know, it is "not to be learned" by people who do not.

Pay-by-bonk 'glitch' means cards can go kaching-for-crims

Voland's right hand
Silver badge

Re: Who knew pay by bonk was insecure? It's bonkers, I tell you

but how are they going to hang on to it? Unidentified?

The only way they can do this is if they set up a merchant (described in the article actually). There are quite a few checks and traceability requirements to set-up a merchant nowdays. So "setting it up" is IMHO out of the question.

Things become considerably more interesting if you "own" a merchant. Instead of lifting the cards, you add your remote pay-by-bonk terminals operated by the pawns around the world to the merchant transaction system. Then you lift the money out of the merchant accounts. This is a tall order - you need to "own" that merchant's infrastructure top top bottom - interface for POS, transactions, accounts and banking backend. Not infeasible, but probably too much effort for the payback you are going to get for a normal "pay by bonk pickpocketing" in bars and malls. Now setting up a 1.5m parabolic antenna aimed at the morning queue at one of the London subway stations or drive by skimming of bus queues... That may be worth it...

Re: The SD card design is deliberate

Surely the issue is the lack of correctly functioning drivers for the hardware, not the hardware itself?

Hardware design is "interesting". Instead of a normal unified power management controller the LID is on a separate IRQ which is not something which is handled by the normal IO. However, lid open/lid close is still presented on the input subsystem so the power manager detects a lid close from there, suspends the beast only to be immediately awaken by the lid IRQ which is in the list of IRQs allowed to wake it up.

So a "driver" is not enough. The drivers function correctly and the events are correct. The problem is the underlying design which supplies more than one event source in a manner which nobody else understands and is inherently susceptible to race conditions. As this is an arm soc which has the "design feature" of a dedicated lid IRQ (it is not even a GPIO pin), getting that folded into the normal input driver is actually non-trivial.

The SD card design is deliberate

The SD design is mandated by the Chocolate Factory, so that you do not use this as a permanent storage expansion and keep all of your goodies in the cloud for monetization. This is on purpose, same as crippling the kernel and exterminating with extreme prejudice all of traces of network filesystems. Though shalt consume and by consuming though shalt be monetized.

Otherwise it looks like a good choice for a travel laptop once the default firmware has been wiped and replaced by Ubuntu. It probably will not require the level of surgery I had to do on the Samsung arm chromebook (I even had to write my own power manager to suspend it correctly on lid close, none of the stock ones work on that abomination).

If I was not quite happy with the HP TouchSmart which has an identical spec, replaceable drive (replaced with 500G hybird already), replaceable RAM (8G in) and better GPU (radeon), runs under Debian (or Winhoze) with no objections, I would have considered it for a Christmas stocking filler.

What ISS does to dump heat is not usable for a reactor

Quote: If I'm not mistaken, they already use radiators on the ISS.

Yes they do (ammonia as a working fluid if memory serves me right), but for nothing anywhere near the amount of heat which is dissipated by a nuclear reactor. They also (ab)use the fact that the station is reasonably reflective and heat insulated by orienting it so that the radiator is in the shade thrown by the station.

The surface area of a purely radiation cooling radiator which operates in the "boiling water coolant" temperature ranges typical for modern nuclear reactors will be enormous. You cannot hide that easily in the "spaceship shade". It will be too bloody big.

The only solution is to increase the operating temperature so your heat transfer rate per m^2 is higher and thus decrease the radiator size. Getting that done and combining it successfully with a nuclear power generation cycle is a non-trivial engineering problem.

Re: Nuclear

Your only means of cooling is radiation which is:

1. Not terribly effective for temperatures under several thousands degrees. You need to make the bloody thing glow to radiate heat.

2. Not something we have invested into over the years. Cooling through heat transfer, evaporation, etc of all shapes and sizes has been polished to near perfection by several millenia of human engineering. Compared to that cooling solely by radiating heat is in its infancy.

Putting the problem of getting a reactor safely into space aside, we need to solve the problem of working with coolants (multi-stage if need be) in the 800+ degrees zone (at least) in order to be able to use radiation cooling. If we do not figure it out the weight of the radiator will outweight any benefits of running propulsion off a nuclear reactor (pun intended).

Re: It was all they could have done*

They already tried Solution 3. If memory served me right, FishKill was one of the sources for AMD and video card manufacturers. That proved insufficient.

It is is still an E.L.E.

It is still an E.L.E. if it whacks us on the head. Thankfully this one should be a miss this time.
