Your definition of math is very limited. Descriptive Geometry is math too.

Path finding systems may use imprecise weight function when making decisions - calculating weights is a major burden.

Using cameras involves image analysis. In essence, you're working with what is a bunch of noise, and you analyze it for meaningful data, by averaging over a whole bunch of unreliable samples. If you can do it 15 times faster at cost of introducing 5% more noise in the input stage, you're a happy man.

In essence, if input data is burdened by noise of any kind - and only "pure" data like typed or read from disk isn't, any kind of real world data like sensor readouts, images or audio contains noise, the algorithm must be resistant to said noise, and a little more of it coming from math mistakes can't break it. Only after the algorithm reduces say 1MB of raw pixels into 400 bytes of vectorized obstacles you may want to be more precise.... and even then small skews won't break it completely.

Also, what about genetic algorithms, where "mistakes" are introduced into the data artificially? They are very good at some classes of problems, and unreliable calculations at certain points would probably be advantageous to the final outcome.

I admit I haven't checked this, but since the character lists are NOT shared between regions (Americas, Europe, Asia) would you not have an actual 3x10 characters available to you?

So that's four difficulties, 30 characters. I'm pretty sure after 120 complete runs through the game you do not want to start char #121, and if you do ... consider seeking help. NO GAME is that entertaining.

A few weeks ago, I foolishly ran a strange executable file that one of fellow slashdotters posted in a comment. As someone who doesn't know much about computers, at the time, I thought nothing of it. "Why would my fellow slashdotter want to hurt me?" Following this line of thought, I ran the file without question.

It was pretending to be a strange anti-virus software I'd never heard of from a company I'd never heard of.

It's not like you can just throw all that data into a Makerbot.

GameMaker, on the other hand ...

How do you suggest making the machinery figure out what needs to be exact duplicates, and what can be defaults? For instance, I'd really hate for it to confuse half my brain matter with generic body fat just because I was asleep or something.

Well. we can still send a half a thousand robotic rovers to Mars for a year much cheaper than one man for a week, with no return ticket.

The problem is even 50 years ago there were things that no robot could do and you needed a man on place, to do them. With all the air, food, water, radiation shielding, waste processing and all this stuff robots don't need. Just because robots were too primitive. And 50 years ago we had the cold war and space race with weekly budgets exceeding yearly budget of nowadays.

Nowadays there is no work that can be done by a human, that can't be done better by a robot costing less than full life support system for the human.

I say: send a bunch of robots. Have them build a good self-sustainable base that will withstand decades of use. Send humans on one-way trip. Develop a return vessel while they work on Mars. Send it to bring them back when its ready.

The article gives a fairly precise FCC answer to the question ow "when":
There are two possibilities:

1) When the court orders so. The decision is then at the sole discretion of the court.
2) In situation of immediate, overwhelming danger, which the shutdown would prevent.

Note 2:
- Mere conjecture of possible harm is insufficient
- the interruption must be very short in duration, only as long as is necessary to preserve the status quo
- The agency must immediately seek judicial review of its decision
- Under the review the agency must:
-- affirmatively provide explanations and evidence to justify the prior restraint.
-- show that there were no other alternatives,
-- show that the shutdown was deployed with sufficient precision to ensure that it did not deny mobile access to other areas.

So, in this case, that was clearly illegal, failing:
- no situation of immediate overwhelming danger. It was known well ahead of time, and while there were some risks, no overwhelming danger existed.
- the disruption would not prevent that kind of danger anyway.
- the agency didn't seek judicial review.
- they neglected alternatives of simply providing more security
- they shut down a whole lot of neighboring areas.

What about pointing them sideways, backwards in relation to your orbital movement direction? The probes don't fly straight away from the Sun, that would waste enormous amounts of fuel due to actively fighting the gravity. Instead, they move in an increasingly wide orbit, by increasing orbital speed they make the orbit longer.
