It's A about F, or A over T. (It's your day for corrections isn't it?)

Yes, stuff like that happens all the time in lots of places. I've seen dual redundant, critical data feeds get run in the same trunking in one place I worked at. Hence my belief that an independent technical assesor should be invited to examine critical systems and their report be made available to shareholders and regulatory authorities. (I know, it's not going to happen.)
If I devise a method of computer simulation of wear on a drill bit assembly (and associated equipment), and use that as part of a process to optimise drill bit design; then I can use that method in-house to make my own drill bits but can't sell the bits, or my services as a drill bit designer, to anyone else (unless I pay licensing fees to Halliburton) because they now 'own' this method of optimising the design of drilling equipment.
When I wrote my comments, last night, I think that BlueStacks was being hammered by lots of people trying it out. Hence, it was very slow to respond. I assumed that it was my logging in to the Bluestacks website and the Android CloudConnect app that made it start working, but this seems to have been a timing coincidence.
This morning, I fired up the Bluestacks gadget on my laptop (without being logged in to ther website and without running or being logged in on the CloudConnect app). It worked within about five seconds and I was able to use my Android apps on the laptop and see editing changes appear on my Wildfire and my Vega after a manual sync on the apps.
It installed first time with no problems on my Windows 7 laptop. It appears as an enormous Gadget on your screen. To 'subscribe' to apps, you need to log in to the Bluestacks site using a Facebook identity; during which you have to give Bluestacks permission to see all your Facebook info (including your friends) and also give it the ability to make post on your behalf (that's what it read like). I was willing to do this since my Facebook account was set up just to see what it was about.
Then, with the Bluestacks Cloud Connect app, from the Android market, on my Vega tablet (not my phone, I'm not that trusting), you can choose which of your installed Android apps to sync over to your PC. To do this, you need to enter a PIN than is provided to you on the Bluestacks website after you've signed in via Facebook.
Syncing over an Android app takes time, maybe a couple of minutes before it appears as an icon on your PC, so be patient. I synced over the RealCalc app, so I had a giant scientific calculator running on my laptop..... cool.
Android calendar apps will transfer over and run but (in my case) do not show any events, claiming that no calendars are selected. I assume this is because they expect to read that information from the phone/tablet itself and cannot do this when running on your PC.
In fact, for any Google calendar/maps/docs/mail/reader, etc application, you'd be better using the PC browser in the first place. (I don't have games and am not interested in them so someone else can comment on those.)
Where Bluestacks is useful is for Android apps that need lots of typing. For this, I synced over ColorNote and PostEver. These work fine at fullscreen and I could create and edit ColorNote notes with full functionality but using a proper keyboard on a PC. These were then available on my Vega tablet and my Wildfire phone after a manual sync at both ends. This is useful if you want to do lots of in-app typing. You use mouse click/drag control as you would use your finger on a touch screen.
Apart from apps that benefit from use of a big screen and a real keyboard, I can't think of anything that would benefit from this in a big way (except for games maybe).
As far as I can tell, you need to be logged into Bluestacks on their website and on your Android device (entering the PIN) for it all to work. Even then, it took about a minute or more for functionality to become available. If you decide that an Android app is not suitable for this treatment, it takes a while for it to be removed from the PC based app menu after you tell the website to 'Unsubscribe' you from the app. I've often found myself thinking that the entire thing had stopped working, but I just had to be patient and give it time to sort itsefl out. It may be that you need to leave it logged in all the time instead of firing it up when you want to use it.
On the Android tablet Bluestacks Cloud Connect app, it's easy enough to select any of your Android apps for connection and syncing, but I can't 'unconnect' those apps that I've decided are unsuitable for the task.
It's impressive that they've managed to do all this and any app that may need lots of typing and would benfit from a big screen is a good candidate for trying with this. Apart from the Facebook login thing and the clunky slowness to get going, I was happy with it.
"... something new in providing both fixed and mobile wireless over the same infrastructure."
Surely, a fixed subscriber is the same as a mobile subscriber, exept that they don't move?
In which case, they don't present any 'problems' with handover; so what is special about this?
(I've probably missed something and I'm sure it will be pointed out to me.)
From the link kindly provided by Willington:
Rather than activate Ford’s suspended sentence, Mr Stobart [the judge] decided to “make it more onerous” by barring him from going to Scotland for three days.
(There is no indication as to why this could be considered as punishment.)
Could you give examples of these 'unceratinty' pairs (or give a link to a suitable article about them.)?
I assume that the link between momentum and position is because if a particle has momentum then it's position will change (and vice versa). I'm wondering which other pairs have this link and if they are similarly related.
Why not Zip it up with password protection (AES 256-bit) then talk to the recipient by phone and tell them the password. If it's important (of course it is) then it's worth putting a little bit of extra time and effort into it. (I realise that this needs staff at both ends who 'know about computers')
That sounds good for use in my Android phone running Froyo, which will act as a Wi-Fi hotspot (with up to five users, I think; or was it three users...?). As I understand things, '3' are Skype friendly in that they don't get snotty if you use VoIP over their data service (unlike my current provider who forbids it in their T&Cs).
"... to stick it to your desk, wall, dog or ..."
If you clipped it (with a bit of padding) to the scruff of a dogs neck, the dog wouldn't feel any discomfort and different people in a family home could then call the dog to them so they could use the phone (or maybe a tablet) for a short time.
I remember making 'fireworks', using potassium nitrate, charcoal and sulphur, back in the '70s. Those were the days, when you could make small and simple explosive devices and nobody minded provided you didn't cause damage or inconvenience. Those were also the days when pure and unadulterated sodium chlorate could be bought by the pound at a garden supplies shop.
I don't remember being able to buy detonator cord or anti-personnel mines though. Maybe I wasn't old enough.
My contacts and calendar (more than one, with different names and colours) are stored in a google flavoured cloud. If I get a new phone, I'll have them all within a few minutes of setting up.
If I wanted to, I could sync one displayed calendar to a PC based one but I see no need for that since my PC based Lightning/(Thunderbird) calendar will store any number of local calendars for me and I can then convert local storage calendar events to Googly cloud calendar events as I require.
My music is stored on my home NAS device (which has an FTP server) so I can transfer music files to my Android phone using the Android FTP client. If I wanted world-wide access at reasonable speed, I could transfer some music files to a web-hosting facility and use the Android FTP client to download them from there, (but that would be silly since I have a removable 8GB SD card in the phone).
All the 'apps' to do this on the phone and on my PC were free. Give it a try :)
Mine's the one with the money saving, inexpensive and very capable phone in the pocket.
"... When a shift-number has been applied, or used, it must be erased from the list and not be used again."
That sounds like an obvious procedure to ensure security by removing a key from the pool so it is not used again. I'd say that the author of that instruction fully understood that it was a security measure that made the encryption 'perfect'.
So why does David Kahn say, “Miller probably invented the one-time pad, but without knowing why it was perfectly secure or even that it was,”
It may be that Miller didn't actually 'invent' it but made sure it was formally known by incorporating the method into the telegrapher's codebook.
Miller may not have known or understood the various and many mathematical theories and techniques that apply to crypotgraphy, but the 'perfection' of the one time pad should seem obvious to any intelligent person. (Or am I applying my own hindsight here?).
In use, I would assume that a shift number was applied to one letter of the message then be discarded, then the next letter of the message had the next shift number applied. If one shift number was applied to an entire message, it would be easy to crack the encrypted telegram since there are only about 30 possible shifts for old-style telegrams.
