NSA man: 'Tell me about your Turkish connections'

Arab Princess at US immigration

Back in the 90's (long before 9/11), a colleague of mine had to go to USA for a training course. At New York airport he found himself waiting in the immigration queue behind an Arab princess, and the immigration officer definitely DID NOT LIKE Arabs, princesses or otherwise. From his vantage point at the head of the queue, my colleague heard the following conversation:

Officer: What's your name?

Princess: Princess XXX of Saudi Arabia

Officer: What's your job?

Princess: Er..., I'm a princess.

Officer: No. What work do you do? What is your job?

Princess: Err... Well, as I said, I'm a princess. I don't actually have a job as such.

Officer: OK. So you're telling me you're unemployed. Well, then, what's your husband's job.

Princess: He's Prince XXX of Saudi Arabia.

Officer: I'm not interested in his title. What's his job? What work does he do?

Princess: Well.. he's a prince. He doesn't actually need to work.

Officer: So. You're telling me you're unemployed, your husband is unemployed and you want to enter America?

At thi point, my colleague decided to move to another queue, so he never heard how that conversation ended.

USB charger is prime suspect in death of Australian woman

Clive Harris

Re: Would a RCD have prevented this?

It depends. The switch-mode power supply in these chargers runs at around 350v DC - the result of directly rectifying the mains, before feeding it into an isolated DC-DC converter. If the fault caused this DC voltage to appear on the output then the RCD may fail to respond. This is because some types of RCD don't always work when the fault current has a large DC component. They use a current transformer to measure the current difference between Live and Neutral, and a large DC component would make the transformer core saturate and reduce its sensitivity. The better RCDs do it electronically, which is more expensive.

Feds crack down harder on 'lasing'. Yep, aircraft laser zapping... Really

Clive Harris

Re: Landing is pretty easy

A good landing is one you can walk away from. A great landing is when they can still use the aeroplane afterwards.

There are two kinds of pilots: those who have landed with the wheels up, and those who are going to land with the wheels up.

Try landing a real aeroplane before commenting

May I suggest that anyone who has never landed a real aeroplane should think carefully before commenting. Landing an aeroplane may look easy, but it's a very difficult thing to do, requiring a lot of skill and intense concentration. You are trying to keep a fast-moving, rapidly descending machine on a very precise path through the air, whilst being driven in all directions by wind, thermals, downdrafts, wind-shear and all sorts of other factors. In addition to steering the thing, there are other vital tasks which have to be performed during this very busy period. Swerving out of the way of the laser is simply not possible - you have to hold to your glide slope precisely. As well as mucking up your landing, you may well collide with another aircraft on a parallel runway. Wearing coloured glasses is not practical - you have to be able to see coloured lights, both within the aircraft and outside. For example, in the event of radio failure (not that uncommon - it's happened to me), the tower will use coloured lights to communicate to the pilot. Any idiot who tries to blind the pilot in this way is attempting murder, whether he accepts this or not. I'm all in favour of heavy penalties.

Feature-phones aren't dead, Moto – oldsters still need them

Clive Harris

There is definitely a need for simple-to-use phones

I recently had to sort out a phone for my father, so I can confirm that there's almost nothing readily available that's suitable. He's no fool, he was working with computers in the 1950's (when you had to wait for the valves to warm up), and he had a minor role in the wartime Enigma decryption work. But time has taken its toll. His eyes are bad, his hearing is terrible and his hands are unsteady. The shop sold him a Samsung Android device which was completely useless. He couldn't read the display, which kept changing depending on what it was last used for, so the act of finding a dialpad require searching through several screens and pressing several icons - virtually impossible with bad fingers and poor eyesight. He needed to put it on speaker mode to hear anything and, again, the required icon was difficult to find and kept changing its position. In the end I found a shop which was clearing out some old Nokia dumbphones. They had big physical keypads, whose functions didn't keep re-configuring themselves, long battery life and a loudspeaker mode that was loud and easy to find. He's managing with that for now, but I don't know what I'll do when it wears out, or when the network can no longer support it.

Re: Do the no-texting-while-driving laws apply to riders on a public road?

There was a recent test case on this here in Melbourne. Someone was giving carriage rides to tourists and was using his phone to book his next customer. He was caught for texting whilst driving the carriage. He was let off after his lawyer successfully argued that it was the horse that was driving the carriage. Perhaps next time they'll insist on breathalyzing the horse, or insisting on it passing a driving test. (I wonder how you'd breathalyze a horse)

Another stupid obvious patent

Nothing to do with the Apple/Samsung lawsuit, but this morning I stumbled upon another equally stupid patent: http://www.cooperindustries.com/content/dam/public/bussmann/Electronics/Resources/product-notices/bus-elx-powerstor-active-balance-royalty-note.pdf

Apparently, someone has patented the idea of using an op amp and divider chain to split a power rail. They're patenting the idea of putting big capacitors on the output. But it's OK, you don't have to pay royalties if you only use their brand of capacitors.

Re: Science: Eleventy Billion! Religion: 0

As I understand it (the maths is a bit beyond me, so I may not be quite right), the "inflationary" phase in the expansion of the early universe requires a brief period of NEGATIVE gravity, hence the rapid expansion. Since General Relativity says that acceleration and gravity are more or less the same thing, this means that the effect on time dilation works the other way round i.e. time slows down instead of speeding up. Also, I think the physicist was speculating on how it would appear if the Observer (capital letter intended) was outside of ALL universes, instead of just living in another "nearby" one.

I suppose the only way you can get your head around that is by visualising the entire multiverse as a giant computer simulation. Perhaps we really are trapped inside The Matrix!

By the way, since we have a "devil" icon, could someone come up with a suitable "opposite" one (an angel, perhaps) to cover this type of posting.

Re: Science: Eleventy Billion! Religion: 0

Err ..Not so fast. A while ago I came across an interesting argument by a maverick Israeli physicist (I forget his name). I didn't understand all the details but essentially he calculated the spacetime dilation resulting from the extreme acceleration that the early universe encountered during this rapid inflation phase. It is well known that extreme acceleration does funny things to time and his estimate was that time would be "stretched" by a factor of approximately 10^12.

The age of the universe is generally set at somewhere around 13 to 16 billion years, depending on who you ask.This "stretching" means that the true age of of the universe, as seen by an "outsider" (Whoever that may be), must be divided by this "stretching" factor. What do you get when you divide 16 billion years by 10^12? Well, near as dammit, it's 6 days.

Religion: Eleventy Billion! Science: Also Eleventy Billion! (because they seem to agree!)

Of course, if the actual age of the universe was only 13 billion years then I suppose that means God got to knock off early on the last day.

Star Wars movie to start shooting in UK this summer

Clive Harris

Star Wars is a remake of The Dambusters!

Has anyone else noticed that the original Star Wars movie was mostly a sci-fi remake of The Dambusters. Consider the opening credits - flying through the sky to the sound of a stirring orchestral march. OK, they updated it a bit by using stars instead of clouds and it was a different orchestra, but otherwise it was essentially the same. Then there is the main theme of the movie. A heroic bombing raid to destroy a vital enemy asset by trying to drop a new weapon onto an impossibly small target whilst under heavy fire. Have a look at the two movies and decide for yourself. I wonder if they had to pay royalties to 617 squadron?

Tinfoil hats proven useless by eleven-year mobe radiation study

Clive Harris
Black Helicopters

Perhaps there's something in it.

Many years ago (back in the early '90s) I was involved in a joint industry/academic study on developing mobile phone technologies, sponsored by the UK government. There were several teams, each working on different problems and each based at a university. My team was at Southampton, (my "alma mater"), studying call handover requirements for very small cell sizes. We all went up to London once a year for a joint conference to see what the other teams were up to.

One of the teams was studying the effects of mobile phone radiation on the human head. To do this, they constructed a (rather ghoulish) model of a head, using materials with similar dimensions and dielectric properties to real brain, bone and muscle tissue.

The results they reported at the first joint conference were interesting. In the 900MHz band there was little absorption of energy. However, at 1800MHz, their model formed a resonant cavity. Effectively, a standing wave was formed betwen the ears, with current peaks around the ears and a voltage peak around the centre of the skull. They stressed that their results were very "preliminary" and needed further work.

At the next conference, a year later, we eagerly awaited the results of their further research. That team didn't turn up - their funding had been terminated. Now, I'm not saying that they found something nasty which was being deliberately hidden. It may be they had made serious mistakes and were closed down because they weren't up to the job, or any of several other innocent causes, but it's left me worried ever since.

Random car shutdowns force Toyota to recall Prius hybrids - AGAIN

Clive Harris

Hydraulic power steering failure

I can't agree with the A/C on the reliability of hydraulic power steering. I have had a failure on a hydraulic power steering system. It was a Citroen, one of the ones with the high-pressure hydraulics. A seal blew out, which caused the power assist to fail in one direction, so it had the effect of pulling the car to one side. It happened in a snowstorm, so it was quite frightening at the time.

I'm currently driving a Prius, but it's a Mk2, so it's not affected by the latest recall. It's got 150000 miles on the clock, it's going fine, and it's the only car I've had which has never broken down on me. (And that includes a brand-new Mercedes which stopped dead on the M25 after spitting out a fuel injector)

As a completely irrevelent side issue, yesterday I took the Prius to a local independent dealer to have brake fluid changed (a tricky job which I didn't want to do myself). He refused on the grounds that he "didn't have a licence to work on electric cars". What the ***!

Volunteers slam plans to turn Bletchley Park into 'geeky Disneyland'

Re: Polish cryptographers!! My father worked on it

My father worked on the Polish coding machine. As a young apprentice draughtsman, he was given the job of preparing engineering drawings based on one of the first machines smuggled out of Poland. The work was done in top secret with an armed guard permanently at the door. He had to hand all materials and documents to the guard when he left the room and he was told he would be put up against a wall and shot if he ever mentioned what he saw in that room. Even in the 1990's he was nervous about telling me about it. He described it as looking like a small typewriter with some numbered wheels on it.

Because of this job, and what he had seen in that room, he was forbidden from doing active service in the forces overseas afterwards, due to the risk of capture (although he did his share of air raid duty in London)

There's more - that she's not saying

It's obvious something has happened to Pamela which has scared the living daylights out of her, and that she can't talk about. Maybe she's forbidden to say, or maybe she doesn't dare, so she's just dropping hints about burglaries and intercepted emails.

Through Groklaw, she's made a lot of enemies, powerful and ruthless people who have lost a lot of money, because she helped to expose what they were up to. People who can pull strings in high places.

Everyone is susceptible to blackmail. Maybe someone's dug up something from her past. Maybe one of her family members is being threatened. Whatever it is, it's big enough to silence her.

With Groklaw out of the way, expect a massive onslaught of attacks against open-source software, and any other form of free expression, at any moment, and with no-one to tell the other side of the story. Truly, we are living in troubled times!

Re: A Scientific Temperature in degrees Fahrenheit; WTF!

Actually, Fahrenheit is a pretty good scale for everyday use. Zero is the point where the sea freezes (i.e. it's too cold to go out), and 100 is when you're a bit ill* (i.e. you'd better stay at home) . So, between 0 and 100 you can venture out, outside of that range it's best to stay at home.

* To be exact, 100F is the body temperature of Mr Fahrenheit's daughter, who happened to have a slight fever when he used her to calibrate his thermometer.

Boeing batteries back under spotlight as 787 burns at Heathrow

Clive Harris

Re: Comets and bean-counters

In a sense, the Comet crashes were the result of penny-pinching. The engineers had come up with an elaborate (and expensive) technique for fixing the panels together which involved chemical bonding, drilling and riveting. The bean-counters then stepped in and decided to cut costs. After all, we're joining two bits of metal together. What's complicated about that? What could possibly go wrong? Their solution was to omit the chemical bonding and then bang in a load of self-piercing rivets (basically nailing it together). Sure they left a few cracks around the sides of the rivets, but think of all the money saved! Of course, when it all came apart at 35000 feet, the engineers got blamed for not anticipating this, and not building in enough margin of strength to allow for it.

Any engineer who's been around for a while designing things will know how infuriating it is when the bean-counters decide to alter your perfect design in the interests of cost-saving, convinced they know better than you, and with no idea of the technical implications of the changes they're making. Usually the consequences are not quite as disastrous, but I've had cases where a design of mine was made positively dangerous because a bean-counter replaced a safety-critical part with something cheaper (and which the sales rep said was "just as good").

(I'm starting to get hot under the collar about this, so I think I'd better use the "Fire" icon)

Maggie Thatcher: The Iron Lady who saved us from drab Post Office mobes

Clive Harris

"Australia needs a good dose of Margaret Thatcher"

Some 13 years ago I applied for our family to emigrate to Australia (driven out of the UK by "Red Dawn" Primerola's IR35 pogrom). The doctor who did our immigration medicals had just returned to the UK from Australia, so I asked him why he had decided to come back. He was reluctant to say anything at first, but eventually blurted out his reason: "Australia is OK but it needs a good dose of Margaret Thatcher".

Having arrived in Australia, I found the solution to one mystery - what had happened to all the union bosses driven out by Thatcher? Answer, they'd all settled in Australia! For many years afterwards I kept hearing those familiar Northern England accents on the news, announcing the latest bout of industrial action.

Dalek designer Ray Cusick passes away aged 84

Clive Harris

The real "Daleks" are the squidgy things inside the pepperpots

Just to be pedantic - the "Daleks" or "Dalek people" (as they were called when first introduced) are not the pepperpots themselves, but the shapeless squidgy things inside them. The story varies but, according to a very early episode, they were reduced to this state by a nuclear accident. The pepperpots are simply motorised wheelchairs to enable them to get around. Since the accident also left them very bad-tempered, they had their wheelchairs fitted with death-rays, armour plating and various similar useful accessories.

The Tardis itself was an ingenious way of getting by on a very restricted budget. They couldn't afford to get a realistic-looking spaceship (timeship?) made up, so they made do with whatever they could find in the props store, and then adapted the story around it. They found the wooden 'phone box in there, so they made up a story about a ship that changed its appearance to blend with the surroundings - except that the appearance-changing mechanism had broken and was stuck in 1960's England. Sometimes, an inadequate budget, together with a lot of ingenuity, can actually improve the story, as well as making it more durable.

"My computer is possessed by the Devil"

About ten years ago I had a frantic phone call from a woman saying that her computer had been "possessed by the Devil". Could I come round immediately, preferably with a priest?

The machine was running Red Hat linux. When I got there (alone - where are priests when you need them in a hurry?), the computer was sitting on its own in a darkened room - the woman was too frightened to go near it. I started it up and waited. After about ten minutes, the screen went blank and then slowly filled with an image of flames. A large grinning head slowly rose up out of the flames - it was smoking a pipe, but I didn't notice at the time. It gave me quite a start in that darkened room.

It was, of course, the Xflame screensaver in its default configuration. I removed Xflame and several other "problematic" screensavers, and assured her that the computer had been thoroughly exorcised. I decided not to mention anything about the daemons and zombies that were still infesting the machine.

Getting spares for Dyson products

Are you able to get spare parts for Dyson products? I'm told that over here in Australia they have a policy of refusing to supply spares to customers. I don't have any Dyson products myself, but one of my colleagues experienced this problem recently. This is done on the spurious grounds that "only a licenced electrician is allowed to repair a vacuum cleaner". That may possibly be true in some states - there are some rather crazy laws around here - but Australians are not renowned for being law-abiding (That's why most of us are here!). It's more likely an excuse to jack up the cost of repairs. If spares are freely available in the UK then there probably a good "grey market" opportunity for some enterprising UK person to supply parts to Australian users.

Do nuclear physicists only have daughters?

It's a common observation that RF engineers father a much higher proportion of girls to boys. Reading this I wonder if that's true of nuclear physicists as well. It's quite likely that both would be exposed to strange forms of radiation at work, so there could be a connection. I don't work with RF or other radiation now, but I certainly did in my younger days, back when safety rules were more relaxed. I frequently stood in the near fields of transmitters, I once stood on top of a nuclear reactor (the Dounreay PFR), and I can honestly say that I once held a (very small) piece of plutonium in my hand. That could explain my two daughters and no sons. Have any statistical surveys been done at CERN?

After finishing, he had to hand the drawings to one of the guards and then forget that the incident had ever occurred (on pain of death).

He described the "thing" to me as being a bit like a typewriter, but incorporating a series of numbered wheels. Even in the 1980's he was nervous about talking about it.

I was caught in a similar situation at Heathrow a couple of years ago. I'd had too many cups of coffee while waiting to board and then, after boarding, the aeroplane got stuck in a very long queue waiting to take off (nearly 45 minutes).

Fortunately, my seat was next to the toilets. I unfastened my seatbelt, dashed to the cubicle and locked the door before the stewardess could react. Within a minute I was back in my seat, buckled in and feeling relieved but rather embarrassed (everyone was watching me). The aeroplane had moved forward about 10 feet in the meantime.

The stewardess gave me a dirty look but decided not to make a fuss. That was Qantas. Perhaps they expect that sort of thing from Australians.

Plural of "Prius"

It's at times like this when you need to know the plural of "Prius". Apparently, it's "Priori".

"Swiss Cheese" model

Aircraft safety is managed through a "Swiss Cheese" model. You accept that every layer of safety, however carefully implemented, will have holes in it, like a slice of Swiss cheese. You can't catch them all, so you add layer after layer, making the cheese thicker, to minimise the chance of any of the holes going right through.

There are procedures in place to minimise the use of mobile phones (one layer), systems to (hopefully) shield the aircraft systems from the mobile phones (another layer), backup procedures in case an aircraft system fails (another layer) and so on. Removing one layer will not necessarily cause a disaster - it just eats into the safety margin. However, if one of the other layers is already compromised (a tired technician forgot to secure some shielding, or a sleepy pilot didn't respond to an alarm), then you've got the makings of an accident.

My own experience...

...taking my daughter for a ride in a light aircraft and waiting for take-off clearance at a busy airport.

Me: "Control Tower. Piper Cherokee Papa Delta Echo is ready for take-off"

Tower: "Papa Delta Echo you are BEEPBEEPBEEP BUZZBUZZ CRACKLE WHIRR"

Me: "Control tower, Papa Delta Echo. Say again"

Tower (distinctly annoyed): "Papa Delta BEEPBEEP BUZZBUZZBUZZ, please expedite."

At that point, I glanced at my daughter in the passenger seat, to see her having a vital "heart-to-heart" conversation with her boyfriend on her mobile. I shouted to her to stow the darn thing.

Me: "Control tower, Papa Delta Echo. Sorry, getting interference. Say again".

Tower (extremely annoyed): "Papa Delta Echo BEEP BUZZZZZZZZ ... for immediate, repeat immediate take-off."

Me: "OK I think that's a clearance". Takes off.

Blimp fireball disaster in Germany, Aussie pilot killed

Thumb Up

Captain goes down with the ship.

Sad, but true. That's how it should be, and it's what they teach (or should teach) at flying school. In an emergency, the commander is always the last one off, and, if that means "going down with the ship", then so be it. If he'd jumped, then, firstly, it's possible that some of the passengers might not have had time to get out. Secondly, the burning wreckage could have travelled a lot further before coming down. As it was, it came down in a field, with no other loss of life.

Having said that, it still takes a lot of courage to do what's required when the crunch comes. We should salute a hero who did his duty to the end. "Greater love has no man ...etc etc". You know the rest.

Desktop Linux: the final frontier

Linux

Modelsim

The interesting thing is that demo copies of the cheap windows version of Modelsim (Modelsim PE) and, (so I'm told) cracked versions, work perfectly on Linux using Wine or Codeweavers. It actually runs a lot faster than under windows. Apparently the only part which doesn't work is the licence manager.

This probably explains their unwillingness to release an official Linux version. It would run almost as fast as the Windows version of their very expensive flagship product Modelsim SE, thereby undercutting its market.
