I don't get it
I have always been slightly annoyed by the slight parallax that comes with rangefinder cameras (and TLRs for that matter). I like to work quite close up and this can be a problem. Why didn't Leica move to a system that puts an image from the sensor into the view finder? There are AMOLED screens available that would give a much better impression of what the camera will record (including DOF).
Still, given the price tag, this is a pretty academic issue:(
An invisible cable
I presume the thinking behind this idea goes: people like wandering around their houses/ cafes etc with wireless devices (laptops etc). The trouble is those toys tend to have a lousy battery life. So wouldn't be neat if they could get their power wirelessly as well? The answer to that question is yes.
However the problem is to get anything like efficient transfer (and Sony's claimed efficiencies are pretty good) you need a carefully tuned set up. The transmitter and receiver need to be very specific shapes and need to be located with great precision. This is where the idea falls down. You cannot simultaneously wander around with something and keep that something in a precise place.
Yes I know Sony are talking about this as a TV supply, but thats a bonkers idea commercially (who wanders round their house with a 22 inch TV?) I guess they used that because the TV was the smallest device that their tuned antenna would fit into...
El Reg bought by the dark side?
The other day Apple got hammered by a Reg hack for improving their iPhone OS. Microdross talk about bringing to WM (a truly dreadful PoS) a couple of features that might be sort of useful and it gets billed as an iPhone beater.
Seems a bit biased to me...
Centripetal and centrifugal forces are both real, but which term you use depends whether you are on the outside looking or actually in the spinny-thing.
XKCD has explored this in a much more entertaining way than I could hope to: http://xkcd.com/123/
I believe a typical house consumes a few hundred kWh per month. So presumably the number on the poster is to do with maximum annual production/consumption.
BTW even in Scotland (the inhabited bits) the amount of solar energy that hits a house is something like 5 times the amount used inside it. The real issue is converting it into useful energy and storing it.
DESY has systems for particle physics and systems for X-ray science. I think you will find that no particle physics was harmed during the discovery of the hidden picture.
"It should be easy for someone familiar enough with the systems who has physical access."
If the sensitive data is encrypted (as it should be) then getting at it without the password will not be easy.
Robb is right, it sounds as though there is a procedural failure here.
Domestic blast furnace?
How many of El-reg's readers have a blast furnace at home? Not many I suspect.
Also, is the Blast Furnace the approved unit of consumption? Surely there is a unit based on the number of the number of sheep that can be sheared or similar?
Paris - because even she could have worked out that the bill was wrong.
In the nineties the Science and Engineering Research Council was split into:
the Particle Physics and Astronomy Research Council (PPARC);
the Engineering and Physical Sciences Research Council (EPSRC);
the Biotechnology and Biological Sciences Research Council (BBSRC);
the Council for the Central Laboratory of the Research Councils (CCLRC).
One of the primary drivers behind this was the vulnerability of the SERC to funding miss-haps from being exposed to exchange rate issues and uncontrollable cost over spends - a particular problem with astronomy and particle physics projects.
PPARC and CCLRC have been remerged to make the STFC (unaffectionately known as Swindon Town Football Club). The EPSRC and BBSRC depend heavily on the big labs now run by STFC. So now on top of the funding shortfall at the setup of STFC UK science is hostage once more to the problems of working on big international projects. Well done New Labour!
Yes, this weapon is pretty useless in its current state. However, those good ole Pentagon people have got a project to develop a 50kW solid state laser underway - I guess Boeing want to make it look as though they have a vehicle ready to go once the laser is ready.
Its a few years off though - the laser should have been ready by 2004.
BTW this weapon cannot be for blinding people as this is banned under a Geneva convention and there is no way that the US military would consider contravening one of those!
More of a troll than a gorilla
I get a bit fed up to see nuclear pushed as the "only" way out of the energy generation problem. The disingenuous nature of the arguments put forward by the nuclear industry and its supporters really annoys me. just look at the amount of CO2 generated in extracting the fuel from ore and the problems with disposing of the worn out power stations (let alone the spent fuel.)
If we'd invested the money squandered on nuclear solutions on technologies such as geo-thermal, solar, and wave energy then the future would be looking a lot brighter (and cheaper.)
