Comment Re:Big advantage? (Score 1) 147

I'm not sure i'd class Liq He as an advantage. Having worked with it i'd call it a pain in the arse, and totally unsuitable for computer cooling. Low heat capacity and insanely low temp mean it has to be transported and stored in large, very well insulated containers, so it lacks the easy mobility of liq N2. Transferring liq He from one container to another also requires some skill if you don't want to evaporate the whole lot during transfer.

Oh, did i mention it gives you splendid burns too.

This is true, but they still need a large user-base to pay for launching a constellation of satellites into space. This was the problem with Iridium v1 - it cost a fortune to setup and not enough people used it because microwave mobile networks were cheaper.

The same problem still exists - the mobiles we all have and love are a better solution for the majority of the market, and that won't change with Iridium v2. Iridium appeals to users who need connectivity everywhere on the planet, and maybe those wanting extra privacy arising from not going via conventional networks. But thats not a lot of people in the overall scheme of things, especially when you are talking about putting up a load of satellites. It surprises me that they have enough users to be able to afford this upgrade.

Wedding photography has a very well established business plan where the base fee covers the basic costs of the photographer, and the prints supply the profit. You are not paying twice for the same thing - the real cost has simply been split up in a way which is convenient to both the photographer and the customer. As it is not exactly an uncompetitive industry, and you don't see many wedding photogs turning up in Porsches, i'd say the pricing and model were pretty fair.

The reasons for the model relate to the photographer having control over his/her reputation, not to screwing the customer - when photos were still taken on film, the quality of the final print had as much to do with the printing process as the actual taking of the picture. Retaining control over that was important to the reputation of the photographer - if he actually handed you a stack of negatives and let you have them printed by any old mail order company, the lousy final prints would impact his reputation. You *could* argue it is an outdated model now, with the rise of electronic media, but most couples still want prints, and the same problem actually still remains - giving out jpg's and letting people print at home or from a cheap online outlet is going to result in exactly the same quality/reputation problem as in the film days.

The industry is adapting to modern times though, so you will now find some wedding photogs will include a DVD of low resolution images for you to put on the web (and many will host a web presence for you as part of the package). But any you find who are willing to give you full size images and reproduction rights for anything less than a big pile of money are probably not the quality of photographer you want covering your wedding anyway.

Comment What if MS go bust? (Score 1) 819

What happens to the authentication if MS goes out of business?

Ok, so its an unlikely scenario, but having someone as big as MS do this will set the trend for web based authentication of everything. How many small companies are going to follow this lead, forcing regular security checks down the throats of customers on the basis that it is an "Industry Standard" way of doing things. And how many of those are going to go bust in a year or two, leaving customers up s**t creak with no method of propulsion?

The problem with any tech is that it's nearly impossible to make it perfect. In some situations like airbags, you can make the system very simple and independent, so it's not prone to failure.

Airbags aren't perfect. I know that for sure as i blew the side impact bag in a VW when a tyre popped. How do you think the car knows whether to deploy an airbag? A lateral g sensor, or in more advanced systems there may be sensors in the doors/pillars. Its still electronics that can go wrong.

Comment Re:I predict a boom in Chinese research. (Score 5, Interesting) 292

My experience echoes this - i review for a number of materials science journals and i've noticed a steady increase in the quality of work coming from the chinese universities. Its becoming well written (in english, which is not easy for them i think) and increasingly relevant. I would predict that before long they will need us less than we need them. The only case of blatant cheating (copying and pasting "nano particles" all over a SEM picture) came from india, not china.
