  1. Re:Don't jump to conclusions... on Opportunity Rover Arrives at Endurance Crater · · Score: 4, Interesting

    I worked in my university's robotics research department during my undergrad studies. My job as a cs student was to write the motion control algorithms for a group of math grad students. The project was to develop an AI that could navigate a building and perform tasks autonomously given a floorplan, its starting location, a destination, and an action to perform.

    The robot platform that they were using had a styrofoam head mounted on top of a cylinder with a pair of treads. The head had two cameras mounted where the eyes would be and two microphones mounted where the ears would be. The idea was that the robot would be able to understand simple voice commands, be able to detect transient obstacles (mostly people) using the cameras, and be able to track its location using the cameras (landmarks) and treads (distance rolled).

    By the end of the semester, we actually had it working halfway decently. One issue we encountered with tracking distance using how much the treads had turned was that the treads tended to slip when turning and also on dusty/dirty patches of the floor, so that over time the internal position diverged from the actual position (which is where the cameras came in).

    Now seeing as how this was almost 10 years ago and it was just a bunch of undergrad and grad students, I'm sure that the specialists at NASA have been able to accomplish something truly amazing with their rover. My hats off to them.

  6. First hand experience on US Expands Fingerprint and Mugshot Program for Visitors · · Score: 2, Informative

    I just flew into SFO (San Francisco International) yesterday from Seoul after a week of business there, and shortly before arrival they announced that for security reasons, everyone had to present their passport as they got off the plane - not for customs, but right at the gate exit.

    On my way off the exit ramp, sure enough, there were four very large policemen there inspecting everyone's passports. I heard one say to another "is this the name?" and the other reply "no, it's the last name we need to check." Obviously they suspected someone on some flight from the region of asia my flight came through (another flight connected to mine).

    Anyway getting to the point, there were a lot of grumbles about the inconvenience and people worrying about whether it would delay them getting to their next connecting flight. Now, imagine not only just checking the passport, but actually getting fingerprinted and photographed - how much more time would that take? And are they going to use the digital fingerprinters, or old fashioned ink? Then everyone has to wash their hands after?

    This is a great way to kill off tourism here. I just love my country sometimes.

    Traffic tickets do not usually bankrupt anybody but hopefully they will get you to follow the law.

    You must not drive around Seattle much. =)

    However, this analogy is rather apt; in (Montana I believe) the cops are allowed to collect speeding tickets on the spot in the form of cash. People have taken to keeping a fifty on the dash so that they can speed through the state, and just pay the fine if they get caught (I don't blame them).

    This settlement amounts to the same thing - as long as you have the cash, keep doing what you've been doing.

    I've always made it very clear that the number was a cell phone number, in case there are ever any legal issues that may arise because of it.

    Sometimes they ask if I have a home phone, to which I reply "no" and that hasn't ever been a problem.

    I have no need for such a telephone line, but I will probably have to get one the next time I move as it still is a requirement for many things.

    Can you name one of those things? I have been 100% cellular for the past 4 years, since I left college. In that time, I have:

    -gotten a job
    -gotten credit cards - visa, amex, discover
    -moved to a different state
    -opened a checking account at BoA
    -received a new drivers license
    -purchased a car
    -purchased insurance
    -purchased a house
    -connected the various water/power/gas utilities
    -opened an active account at Schwab
    -subscribed to cable television and modem service
    -taken classes part time at a local university

    Not once has the fact that my contact number is a cell phone been a problem for me.

    Notice that there is no slot for inserting a flash card; unless it supports an external flash drive connected to the PC via USB or similar (doubtful) this means you will not be able to watch the majority of cable hdtv channels, since they are usually scrambled and require a flash card with the decryption information in the cable box.

    This comment is marked funny, and depending on how much radiation the things he mentions actually put out it might even be insightful, but there have been several studies showing that continued exposure to very low levels of radiation is actually more damaging to cellular DNA than periodic exposure to moderate or high levels of radiation.

    It seems that repetitive small damage to DNA is harder for our repair mechanisms to handle than bursts of significant damage are. There was an article in Discover about this a few months ago.
