"Pakis..." I suppose you must be from Great Britain, probably one of those "old school tie" types who think those savages should still be all under the Queen's boot.

Yes i'm from Great Britain, but what I think I that the colonials should be using 220-240V, not 110-120V. Since P=i^2*r and i is proportional to v, resistive power loss in the cable the cable would be cut to 1/4 of what it is today, greatly reducing the risk of excess heat in skinny power cables.

Apple doesn't allow access to UDIDs (universal device identifiers) anymore, so unless the software is quite old, or requires a jailbroken device, the prosthesis cannot be paired to the device. (That's one of the reason why you can't access the UDID anymore, because pairing information with a device is stupid; the bigger reason is privacy).

The prosthesis can easily be paired to an AppleID plus an application specific ID. However, all information about this would be stored on the device, backed up to iTunes, and could be restored by just buying a new phone, entering the AppleID and password, and downloading the last backup.

If that doesn't work, then these guys must have some really strange and stupid software design + implementation.

Any app writer can include their own magic number in the instance on the device and use that for pairing.

Solar cells on every house is great as long as there is local storage in every house too.

Wind power is great as long as there is good power distribution infrastructure: It's always blowing somewhere.

Nuclear power is great as long as you address operational safety and waste storage, both of which are addressable if you do engineering rather than politics. Part of that is again, good infrastructure so you can build the nukes in good places for nukes.

It's easy to point at any single generation or harvesting technology and identify it's flaws as a sole solution. However there are many technologies and combined together they form a robust and comparatively clean solutions.

If there was any data to suggest the ACT tests are statistically valid (they test the thing you think they test) or reliable (they would get the same result if you tested again) then the correlation may be a clue to something. However when the underlying test is neither valid nor reliable, the correlation it shows doesn't even show you there is correlation.

Layout tools, Schematic capture, logic simulators, analog and mixed signal simulators, P&R, floorplanning etc, etc.
The all have a GUI that needs to be used.

What's notable is that with all these tools, the specific ones I use in the company I work for making big-ass chips, precisely none of them work on a windows desktop. You either run them locally or remotely on a Linux desktop. As time goes on they tend to drop support for older unixes. I don't know anyone who runs these on anything except Linux these days and windows is just a platform to run X or VNC to get to the desktop of the Linux box running the tools.

>rather than trying to break into the standalone desktop OS market.

It's there and dominant in a whole host of industries. The western world would collapse if Linux ceased being available on the desktop. For example we couldn't make chips.

But the eastern world would be ok?

Yes. They have good bread and public transit.

Can't open /usr/fortunes. Lid stuck on cookie jar.
