Re: Push-to-talk latency
Affirmative/Negative means simply yes/no.
"Rodger" has a very specific meaning, at least in UK military usage, which is "Your last message was received, I understood it and am carrying out any orders contained within it".

The amount and type of data sent back from the aircraft is determined by the customer (the airline) options selected; i.e kit fitted and service level agreements with Inmarsat, etc.
If I recall correctly, MAS had opted for only very basic data reporting services through Inmarsat, so once the aircraft was out of range of land based VHF ACARS sites options for transmission of data was limited. Add to this that the ACARS system on board appears to have been disabled, either through deliberate interference or accident, then the lack of data from the aircraft isn't surprising.
Some insist that the fact that ACARS was disabled, but not the SATCOM radio points to deliberate interference; it's possible to just log off ACARS from the flight deck, but disabling SATCOM would have involved a trip to the aircraft's avionics bay (located below deck and accessed via a hatch outside of the flight deck) to pull circuit breakers. It's been suggested that any fire would have taken down all systems equally, including (as you pointed out) the autopilot, causing the aircraft to crash a lot sooner than it did.
It's a weird case and I don't think we'll ever know the full story, even if the flight recorders are recovered. The CVR has a loop time of 3 hours, so any voice recordings of the beginning of the incident has likely been lost. The investigation will have to rely upon the FDR, that has a much longer recording period.
787 is a twin engined aircraft.
By using electrical systems to replace traditional hydraulic and bleed air (pneumatic) systems you reduce the requirement on the engines to power said systems, meaning they can use more of their energy propelling the aircraft. E.g. de-icing systems that use bleed air reduce engine power enough that their use is factored into takeoff distances.
Also, doing away with these systems allows you to remove the associated equipment and ducting and therefore weight. E.g. if you are no longer using high-pressure, high-temperature bleed air from the engines to pressurise the cabin, then you don't need such complicated systems to reduce it down to a usable pressure and temperature for the task. An additional benefit is that you also no longer have the risk of oil, etc contaminating the cabin air.
To be honest, that might hold true for consumer level cameras, but £5k pays for a lot of film and processing. Not to mention the fact that hi-end DSLRs have a much shorter service life than pro film cameras used to, due to the rapid march of technology.
Film vs digital costs are notoriously difficult to compute as the variables are complex, but I'l wager the savings aren't as large as you think and much of the cost of digital is up-front. In addition, digital has extra costs related to post-production that can be difficult to sell to a client, for many of whom "digital = cheaper".
If both side sticks are moved at the same time an aural warning "dual input" is given by the aircraft.
In addition to this, there is also a visual warning light on the glare shield, just below the pilots' eye line, that illuminates to indicate that the other pilot is making control inputs.
Pressing the red button on the side stick gives that stick priority and cancels out the inputs from the other stick.
I suspect the reporting of "subliminal messages" has more to do with the gutter press misunderstanding the concept of steganography, that some comedy, backwards masked nonsense.
Some CIA type probably mentioned that they were checking to see if there are any "hidden messages" embedded in the images - gutter press hears "subliminal messages" and runs with bollocks headline.
I believe you are confusing a licence with total copyright buyout. When a client commission work from me they are granted a licence to use/reproduce that work in pre-defined ways and for an agreed period of time. The licence may also stipulate exclusive or non-exclusive rights to the image.
A client may wish to completely buyout copyright in perpetuity, but they should expect to pay a price commensurate with that level of control.
Finally, the majority of images that I supply to clients are in digital form, so I don't know what you're wittering on about CD/DVDs for. In this digital age it's not unusual for images to only exist in hardcopy at the final stage of going to a commercial printer.
I have found images that I created, which have been stripped of their metadata by a third party (by accident and on purpose). If these get into the public domain then it is not the fault of the author that they can't be identified.
I'll think you'll find most authors of creative works keen to be identified correctly.
It does seem like rather a lot, doesn't it?
I seem to remember from my TA days that the first field dressings that we were issued were designed to hold about a pint of blood. When blood spots started to appear on the outside of the dressing, you whacked another one on top of the previous - up to a maximum of three.
The logic being; someone who has lost more than three pints of blood is very likely to die and therefore you should direct your efforts toward casualties with greater survival odds.
Simple, if a slightly brutal, logic.
For me, the new masking and edge detection tools, alone, made it worthwile.
HDR is a bit of a parlor trick really; there are companies making specialist HDR software that's much more flexible, when compared to Photoshop's implementation. Still, it has been improved again in CS5 though.
Every new version brings lots of incremental improvements (important workflow ones, not Ooh Aahh marketing ones) that makes it worth upgrading; things like improved 16bit support and the ability to use smart objects for more and more things.
I'd image that the choice of a 4:3 aspect ratio is that it's closer to the traditional photographic sizes than 16:9 widescreen. If fact, I can't think of any professional stills cameras that shoot in 16:9, although I do have a Fuji point & shoot in a drawer somewhere that had it as an option.
Here in Glasgow, there are already Asian FM stations that are very popular. In contrast, there are currently no commercial offerings that could replace 6 Music.
That said, I don't want to see either axed.
Also, do we need 1Extra, that is just a continuation of the bland, RnB shitfest that is Radio 1?
What the hell are twittering about? No one is suggesting that what you have written above is a good idea.
The problem comes from a bunch of scientists who have allowed their beliefs get in the way of proper science and have acted in a manner that has now brought disrepute upon their work. Their actions have strengthened the case of the very people that they despise.
Get rid of the one radio station that's actually worth listening too!
6Music is the jewel in the crown of the BBC's current line-up; a wide range of really excellent music, played by DJs who actually know what they're talking about, rather than fat, talentless knobs like Moyles.
If 6Music is canned, then the Beeb's last chance of a digital switch-over through anything other than coercion will disappear with it.
In a previous job, I worked for an arms-length, quango type company that administered an EU funding stream for the Scottish Executive.
Part way through my employment they changed the process that applicants used to claim money, from paper forms to an online system. This system (which arrived several years behind schedule) was designed to run on IE6, and although we found it would run on other browsers, it would often do odd things. On one occasion I recall phoning the Exec's IT peeps on behalf of a small voluntary organisation who, to save money, were trying to run entirely using OSS - their response upon hearing that the applicant was running Firefox was "Oh good, we don't need to deal with this one.".
We also had remote access to one of the Exec's internal databases through a web front-end, which, you guessed it, only ran on IE6.
I wouldn't be surprised if both these system are still around and causing misery.
Definitely too costly, unless you have either an iPhone, or a top-tier talk plan. Whilst everyone has been moaning about the supposed 750MB cap on Orange iPhone data (you don't get charged for going over it, by the way) it's a damn sight more generous than most other plans. Take a look at the cost of data bolt-ons, they're pretty pricy.
It was this, coupled with rubbish speeds that kept me from using data much on previous phones, smart or otherwise.
The reason for the IP rights control is not to stop UK troops from buying their own kit, it's to stop some of the cheap, nasty kit that gets produced by less than reputable companies. This cheap kit usually doesn't meet the NATO IRR specs, meaning that you literally glow in the dark, when seen through night vision optics.
Commercial producers have been involved in the procurement process from the start and will be granted licence to produce good quality gear that meets the correct specs.
