Re: short range is good, but...
Water does not have a great effect on NFC. NFC uses a magnetic field not EM waves (think transformer coupling rather than radio waves). This explains both the short distance it can communicate and how it can transmit sufficient energy to power a micro-controller (NFC can do a lot more than simply read tags). UHF tags use EM waves and so can be read at a long distance, however the energy transmitted is so weak that they can only respond with an ID.
Here is a link to an image of the app, it looks harmless enough.
Men in their 20's will always be overdosing on testosterone, thereby guaranteeing the continuation of the species. It is nature dear, you can only go so far with forcing people to hide their sexuality.
Re: Phones with NFC ?
Other (future) applications perhaps?
Today the "killer" application is payment but there are God knows how many other possible applications out there. The important letter in NFC is the N, if you can thing of an application that transmits data or performs an action simply by touching another object with your telephone you have a potential NFC application.
Re: Laser scanners on reflective screens
Could it be because 1D laser barcode scanners work on reading the reflection of the laser beam so need a support that is based on reflection (e.g. paper) and not on emission (e.g. telephone screen)? However scanners that are based on a camera (some 1D and all 2D barcode scanners) will work with both reflective and emission based supports.
Re: NFC enabled Phone
In theory no, the contactless standards takes in account the possibility of several cards available at the same time. The terminal will detect all the cards (including the NFC phone) and choose one to communicate with.
Re: Seems again
"they deserve every lost £/$ they suffer."
The electricity companies will not lose a penny, they will just put up the cost of electricity. As long as most people stay honest, then honest people will pay.
The local rag
Looking at the comments section on this article in the local (Tyrone) paper, it looks like most parishioners think that he has been framed. It seems as though he has upset some people in the parish who have been trying to force him to leave for some time.
So with this attack my Google wallet becomes as secure as my normal wallet. Well not quite, if someone steals my normal wallet they can use my cards immediately. If they steal my phone they will to do a far bit of manipulations on it before they can use my credit cards.
This is all wrong
Surely global warming should cause glaciers to grow? Global warming heats sea causing more evaporation so more humidity in climate. However hot air reduces rain fall meaning more humidity reaches in-land mountain ranges resulting in more snow and glaciers growing rather than shrinking.
"If this happens there is suddenly no market for a phone-based NFC system"
It already has happened. Contactless payment cards exist in the USA, France and many people unknowingly have them in the UK. I suspect that when the contactless cards and NFC phone systems are up and running it is the contactless cards that find themselves suddenly without a market.
Why will people interested in the convenience that paying instantly by phone will give them? The same reason as why people buy grated cheese. When someone first started selling grated cheese it was ridiculed in the news, how could people be so lazy to pay someone to pre-grate cheese for them. Once it is there people will use it. Once NFC is in phones you will be surprised by the number of applications people will invent for it.
People who want to hate someone will always find an excuse, a way of differentiating themselves in order to turn a group of people into enemies. In the early 20th century there were problems between Catholics and Protestants in England but then with the mass immigration that occurred in the 60s those who were bent on hate found new targets instead.
Most religions preach pacifism. Those who do not attempt to be pacifist cannot correctly claim to be aligned to such a religion. For example, Catholics and Protestants who attack each other cannot claim to be Christian. Calling themselves Catholic or Protestant is an abuse of the label. The fighting is not caused by too much religion but rather a lack of it.
Crap time-shifted is still crap
Being a TV addict I made up a PVR using MythTv. At the time I thought, "Great now I will only watch good programs", so I ended-up hardly ever switching the TV on. The iPlayer is fine for the little that I watch these days.
I bet the 300 people they questioned work in marketing in the electronic wallet industry. "And do you think most people will be willing to pay more than 25p to charge their wallet?" "Of course I do otherwise my job makes no sense and the company I work for is bankrupt"
Typical rubbish that comes from thinking, "How can we make money from this market" instead of, "How can we fix this problem".
It is an option so it depends up on how the store is set-up. Before the selfscan tills Safeways use to let you scan your things as you put them in your trolley and pay on the way out of the shop. They would stop people randomly to check they had not made any "mistakes".
The world minus the UK is still a big market place.
This an exceptional case which is why it is in the news. The woman was 45 when she divorced him for lack of sex for 21 years (i.e. from the age of 24) !
This does not compare to one's wife's right to say no when one returns drunk from the pub at 3:00am.
Screw the French
As with everything in French politics this letter is a set-up. Sarko has increased taxes for the rich and for the poor so it all seems far, except as the letter requests the increases in tax for the rich is an exceptional one-off levy, the increase for the poor is permanent.
August is always a bad month for workers in France. Most of the country goes on holiday for the entire month, so this is the month the government screws them - every year. No wonder the French go on strike every autumn.
Its a magnetic coupling not RF
I know everyoopne calls them RF tags or cards but NFC and contactless smartcards work by magnetic couplings (like a transformer) not by radio waves. This why you can read them from a few cms away but not 10 metres.
This is why NFC is better. If your battery is flat there should be enough energy coming from the reader to power the SIM or the secure IC in the telephone. Even with the battery flat you should still be able to use a ticket based on NFC.
Shouuld have paid attention in math class
"40 per cent customer growth and 20 per cent revenue growth means only half of new users are paying for Skype"
Assuming you can say anything from the figures above it would be that new customers only spend half of what the existing base of customers do. I doubt very much that half of new customers pay for Skype.
I always found it strange that I should find only one or two windmills turning in a farm when most of them were stopped (at least that is commonly the case here in France). If there is enough wind to turn one of the windmills then why not all of them? The reason I have been told is for political reasons: the one windmill that is running is being powered by electricity using its generator as a motor as EDF does not want the public to commonly see entirely stationary wind-farms.
Might be true, might be false, however it the best reason I've been given yet.
I work in sales and I had a colleague who used to have to visit customers with a laptop with keys missing from the keyboard. IT had got fed-up replacing his laptop every time it got a little old and his keyboard "broke".
There is no safe dose
"you can have a pretty good guess at the ability of the body to repair it in time before it becomes a problem."
Your assumption is wrong. Radiation damages your DNA and DNA cannot be repaired. Any DNA damage will be passed onto new cells. Hence radiation damage is accumulative and this is why there is no safe dose .
Safer than coal
2,433 coal miners died last year in China alone. Nuclear power is safer than it appears.
Lack of motivation if your only motivation is money.
Flash cells leak, the retention is typically only 10 years, not very long for photos.
If you have CRT wait 6 months/ 1 year before buying LCD. HD Freeview is comming and if you don't have a HD tele already you might as well wait for one with a HD Freeview tuner in it at a reasonable price.
I cycle to work in the Parisian region and most commuters on bikes are quite sensible, surprisingly the vast majority of motorists as well (assuming they can see you)! Most regular adult cyclists now use lights and hi-vis vests. You still get a lot of teenagers and non-regular cyclists who do not use lights, I can't figure out why when they are so cheap and convenient now.
You get cyclists carefully going through red lights and down one-way roads. The biggest danger for pedestrians is not cyclists on the pavement but the number of motorcyclists who use the pavements as high-speed rat runs.
The biggest killer for cyclists is what they call "l'angle de mort", the blind spots around lorries and busses. A lot of people are aware of the blind spots at the sides of lorries but are not aware of the blind spots in front of them.
SHA1 is "broken" just means that that there is an easier attack than that printed on the tin. I.e. in the case of SHA1 there is an attack that uses less resources than a brute-force attack. It does not necessarily mean that the attack is practical.
The attack in the article on "The Register" is a brute-force attack on short passwords, as the article states the only thing clever about it is how it uses the technology. The attack is not related to SHA1, it just so happened to use it, it could use any algorithm. The attack is not against SHA1 but small length passwords.
Saying this attack breaks SHA1 is a bit like saying RSA is broken because someone did a brute-force attack an 46-bit RSA key.
"No facts just politics". That is exactly why he resigned, he did not resign because he disagreed with global warming, he resigned because the scientific establishment forbids debate. He resigned because the vast quantities of money involved in climate research has corrupted the scientists so much they can no longer be considered to be performing science.
"of Rom women shoving everyone aside so that they can get on the tram, of fat Rom women sitting on the pavements shouting insults at anyone who doesn't give them money."
I've been living in Paris for twenty years, I have never seen Roms acting this way. France has changed radically over the last few years. Two years ago no one took any notice if a woman wore a veil in public, now she risks being attacked if she should do so.
You appear to be a little confused. Roms do not originate from Romania, Romanians do. Why dedicate a part of Romania for them? Why not designate Kent or Yorkshire?
Why do you think Roms have a magical ability to travel across Europe without crossing borders???
Missing the point
The problem is the president of France has publicly started to blame foreigners for crime and has started targeting an ethnic minority on mass. Several weeks ago some police were attacked by Roms after they has shot one dead. The big clean out of the Roms appears to be a collective punishment for this.
This has nothing to do with religion. If religion did not exist this bloke would find another way of finding a group of people to hate.
3D programs strike me as far to difficult to create to become main stream. For example, how can a 3D camera zoom-in? In 2D you just need a special lens to zoom-in and give the impression of getting closer to the object. But with 3D you will also need to change the angle of vision of both of the cameras, i.e. the cameras will need to move further apart by an impractical distance.
3D will fail as soon as people realise that they have been had by the HD con. We've all forked out on new HD TVs, but the programs are still just as crap.
The UK was 240V and the rest of Europe was 220V so to harmonise the supply voltages throughout Europe the EU decided everyone would have to conform to 230V +-5%. So no one needed to change anything and we are now on the same voltage as the rest of Europe! Clever but pointless.
"It will be like the guys in France who were arrested". That was in the UK, the police used it in a terrorist trial.
RFID does not use RF
Banking cards and Passports are often refered to as RF ID parts. Here the RF is a misnomer. The cards do not use radio fields but magnetic fields. The communicatoin is done by transformer couplings (this is also how the readers power the cards). Magnetic fields do not travel in the way electromagnetic fields travel, hence you will start to struggle to communicate at a distance of more than 10 cm with these cards.
(NFC works the same way, hence "Near-Field Communicatoin")
