And what if I happen to be a visiting contractor, and I have an emergency while on the grounds, without a guard in line of sight? What if I'm driving by and break down right in front, and the prison microcell is more powerful than ATT's nearest tower?

Then the guards would be alerted to your activities and that "no guard in sight" situation would change. Problem solved.

Anyway, why would they let you into a prison as a contractor with restricted items, unguarded?

That's what I meant.

If you used a solar cell as a light sensor, it'll deliver just a few milliwatts that you'd have to amplify anyway.
With this technology, you could place one of these cells on top of an amplifier, and apply power to the whole thing. It would then give you a reading of ambient light in a more reasonable range (say from 0V to V+), straight from the chip.

This could be useful as a one chip light sensor, say for a digital camera.

It would simplify light sensing equipment a lot, leading to very low prices.

Because there are dishes on the ground perfectly capable of doing that job that don't cost nearly as much.

Actually, there are not many antennas bigger than that one. It is roughly the size of one of these puppies. The only bigger antenna I know of would be the one at the Arecibo observatory.

On the other hand, you're probably right, as the space agencies would now use arrays of little antennas to look out into space.

(That monster must be sensitive as hell, those 70 metre antennas have been used to communicate with far away probes that had problems with their high gain antennas, imagine the sensitivity of one of those just 20000 KM away)

Japanese is typed using a more-or-less standard QWERTY keyboard.

...then requiring the input to pass through what amounts to a tokenizer to get the phonetic spelling, and into another program, which needs a database of words and has to prompt you for each one in order to select the proper one from a list.

Not something as simple as writing ASCII by a long shot.

The article mentions that a classroom has not changed for the last century, and Laura Ingalls would instantly recognize one. The article writer seems to consider this some sort of disadvantage, without considering that form should follow function. In other words, a classroom is virtually identical as a 19th century classroom because teaching methods have not changed that much since that time (meaning a teacher telling and showing things to a bunch of students).

Classrooms are clearly adequate for their current purpose, and they will be unless some other way of teaching is found. Instead of changing the classroom, making it inadequate for the current teaching methods, the article writers should concentrate on more efficient teaching methods, and the changes in classroom design will come as soon as the need arises.

And if they comply, you would be proving you are indeed the squatter.

In other words, don't do it and contact a lawyer first. Once you're cleared, you could do it as a token gesture for your company.

The only thing the squatters can do to prevent you from doing the transfer at a later time would be to change the registration. Considering the situation, that would add evidence pointing to the real culprits.
