It's all about who you employ
These leaks are failures of vetting, and failures of need-to-know policies. Both become difficult to maintain when the numbers of employees in the organisations reach the numbers in GCHQ and NSA.
Some UK houses have them to feed a standard lamp from the main room light switch, or as a dedicated supply for an electric heater on night tariff, or even as a supply for a clock.
Twisty roads aren't as dangerous as straight ones with occasional blind corners/dips. I live on one of the most dangerous roads in Scotland, the A70 which, like the A9, couldn't be described as twisty.
The bbc news website version of this story has a lot more detail, including about how the scientists came to their conclusions. I'll leave it to you to find the link for it as our hosts here might not like me putting it up.
Re: Bang on...
Giving her something like that has the benefit of lowering her expectations, and forces her to be more explicit about what she would really appreciate instead of expecting you to mind-read her.
Re: ...torches can be like pencils or tape-measures...
I discovered stainless tape measures, they work even if it rains.
Just install the Flashlight app.
Re: Nice idea but
Yes, I'm sure, my work is developing thermal cameras. Thermal cameras show thermal radiation, from which actual temperatures can be inferred, not just differences in temperature. Walls and glass windows are opaque to thermal wavelengths, the wall will show a cold patch if the cold water is directly hitting and cooling the wall.
The heat from a person gradually spreads through the rubble through both conduction, convection and draughts. Thermal cameras can resolve very small temperature differences, in the order of 10s of milliKelvin, allowing you to see these effects.
Post Office 746 classic telephones (new but old stock with new cables) are still available after BT found a warehouse full of them and sold them on. They come in rather fetching 1970s colours.
Are you sure you want to do this?
This could be soliciting for information, and there is no "in the public interest" defence under the Official Secrets Act.
Re: Am I the only one...
It would be even better if they ditched DCT based compression for one that seamlessly supports decode to lower resolution, e.g. wavelet, for then the tv/mobile would only need to download enough resolution to fill its screen/bandwidth limit.
Motorola and Nokia have shown how fickle the mobile biz is, one minute you're top of the heap making huge profits, next you are losing money on every phone you sell.
Smart meters monitor voltage? Why?
You don't need smart meters to reduce demand peaks. Smart appliances monitor the mains FREQUENCY as it drops when the generators are overloaded. Voltage is automatically adjusted by the substation changing transformer winding tap.
The PC bios has been disassembled and clean room rebuilt many times. Having the source code can help to find weaknesses, but a black hat still needs to look at the machine code dump to confirm one. In any case, if they were trying to make it very secure, they ought to publish it for others to analyse for weaknesses, obscurity is not security.
Re: RE: 100 amp 3-phase supply installed
Decent metalworking lathes are typically run from a single to three phase invertor these days. You do not need or even want the high power availability of pukka three phase, if the tool catches in the workpiece your lathe will be in bits. Inverter drive also has the benefits of continuously variable speed, and soft start.
Re: @ frank ly - @ M Gale
The butler tells the housekeeper to tell the servants to go shopping? No, the vendors come to the tradesmans entrance to drop off their goods. You cannot possibly know a typical Rolls Royce owner...
It would be very embarrassing for Apple if the court ordered that their execs be imprisoned for a month if they ever set foot on British soil, the media worldwide would enjoy that. It's hard to see what else the court could do.
Having employees strongly motivated by money in the intelligence community would be a security risk.
Jury of Your Peers
A Jury of Your Peers is an outdated form of justice, where a Lord would be tried before a jury of Lords, avoiding being automatically found guilty by a jury of serfs. A juries are now selected from lists of voters.
Is the vacuum maintained during the delay between the igniter firing and the motor burn? The smolder could slowly reduce the vacuum to the point where the motor burns properly, which won't happen at altitude and could lead to an in-flight failure.
Our chip shops (Edinburgh) sell deep fried battered spicy haggis as well as the standard (premium?) stuff similarly attired. Would like to see it in spicy batter with curry sauce, mmm.
"Write information on them too many times and you'll only be able to read them after that."
No, it will progressively get smaller as the flash blocks wear out. When the number of usable spare blocks drops to zero, you will need to delete (erase) data off the SSD before you can store anything new.
The bigger problem is that the filing indexes are also stored in flash, and when you run out of spare blocks to store them, the entire SSD can fail. The vendors tend to over provision the spare blocks to mitigate against this, but how successful has this strategy been?
Re: Why hasn't anyone considered using goats?
Goats are browsers, not grazers. They'll eat all your plants, bushes, trees, and washing on the line before jumping into the next garden to do the same, leaving the grass to grow. If you want grazers, try sheep or geese.
Yep, yet again.
I had this, the update even corrupted the installer files, preventing uninstall. Nuked .net entirely with the dotnetfx_cleanup_tool, it's amazing how much quicker the machine boots without .net.
Re: Solar ignition!
...or launch when going dark, to get ascent footage during daylight. You could even use the same camera.
Thought it was 1 April again...
I work in a consultancy doing endless embedded microcontroller designs. We typically choose between something like an MSP430 from TI for the lowest power consumption, an ARM variant for decent performance, or a DSP like the Blackfin for high performance. Customers often have different processors which we are happy to work with, but they're not Intels. Intel are in old designs or used by people who don't really do embedded and stick a micro sized PC into their product.
By the way, many smart meters use MSP430s rather than PICs or ARMs.
There's another contender...
Have you seen the Nanotron NanoLoc devices? Uses chirp spread spectrum to get range information.
Of course two independant GPS receivers fix will wander relative to each other; they are free to use different satellites. Differential GPS involves generating corrections for individual satellites, not subtracting two GPS receiver fixes.

...or even have to pay them more than the manager overseeing the project: Managers are easy to find, good techie skills aren't.
Re: Re: Tightening a connector?
That's just one of many reasons why you shouldn't use a GPS 1PPS output for anything requiring accurate timing. Use a proper GPS timing receiver that has a high accuracy clock built in that is directly compared against the measured GPS position/time solution, and will also tell you the difference to any other time signal of you feed it.
Atomic clocks are not stable. They are long term accurate, but need to be phase locked to a quartz crystal oscillator to produce a short term stable output. Chaos theory etc.
Tightening a connector?
60 nanoseconds at the speed of light (299,792,458 m/s) would be nearly 18 metres. Taking into account the relative propagation speed of a signal in a typical coaxial cable at 0.7 they would need to take out 12 metres of cable. A poor connection might introduce resistance and a slow rise time, but if they are basing this measurement on the timing pulse output from a GPS receiver then they deserve the results they got.
Making adjustments based on assumptions invalidates the raw data. You need to find better raw data. The whole climate 'science' thing is a huge load of assumptions constructed into a computer model which can then be tweaked by more assumptions into producing whatever result you want, which is then presented as fact. The CRU are in deep trouble, not just because of their behaviour towards others interested in the topic, but with their sloppy methods and record keeping. The suspicion is that their scientific rigour was so poor not even they could replicate their results.
It's marketing blurb. Potential losses could bankrupt both the provider and their hardware suppliers.
