Revocable biometrics exist, and you don't have to chop off your fingertips either: for example, http://www.turbine-project.eu/ or http://vast.uccs.edu/biodistmet.html or http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4318487 and so on By the way, not to be a grammar nazi, just informative: did you ever tried -> did you ever try

Not the image anyway. They store the relative positions of specific details of your print. 2 minutes on Google would have told you this.

Unfortunately this is pretty much the same thing in terms of actual security (see http://biometrics.cse.msu.edu/Publications/Fingerprint/FengJain_FMModel_ICB09.pdf)

FYI my professor happens to make exactly what you are looking for. In a nutshell, we create a non-invertible biometric template. You can think of it as a kind of "fingerprint hash". If the server is ever compromised there is no way to recover the fingerprint. Plus it's managed like a public key infrastructure, so you can actually revoke it if it's lost / stolen. Here are some of the papers he's written on this technology:

http://vast.uccs.edu/~tboult/PAPERS/biocrypt-scheirer-boult-biosymp2008.pdf

The company he runs has already created a secure biometric login system which uses these secure "biotopes" to automatically log time tracker entries (basically a secure biometric punchcard system). If you have any questions, please contact my professor:

I know it's popular to suggest that marijuana isn't that bad, and perhaps it is. But that's really not a judgment to make until the facts are in. It's been less than 20 years since the more potent varieties have shown up, and it would be surprising if there were any reasonable conclusion for at least a decade or two.

To expand on your point, there are four types of measurement scale, each of which only supports the arithmetic operations of its own type and those of the more restricted types. They are, from most restricted to most general, with permissible operations:

Nominal Measurement Scale [e.g. phone numbers]- Counting
Ordinal Measurement Scale [e.g. serial numbers, class rank]- Greater than or less than operations.
Interval Measurement Scale [e.g.Fahrenheit, Celsius - scale divisions of equal quantity]- Addition and subtraction of scale values.
Ratio Measurement Scale [e.g. length, mass, Kelvin - interval scale with a unique, meaningful zero point]- Multiplication and division of scale values.

See http://web.uccs.edu/lbecker/SPSS/scalemeas.htm for more on scales of measurement.

Additional information...

In addition to Long Valley Caldera, there are other geologists who believe that Mt. Rainier in Washington might be due for an upcoming cataclysmic eruption - Apparently, this mountain is quite active, and has been responsible for some really nasty fast moving pyroclastic flows in the past - Some which have made it as far away as Tacoma. There was a NOVA episode about this. One of many interesting sites on this is here.

It wasn't one of the most recent fireballs, but the one on September 6th.

It was probably around 8 at night and I was walking back to my dorm room (Univ of Colorado at Colorado Springs) from work. I was almost back to the campus when I saw a bright but small fireball in the northeast sky. Mostly white with a bluish tinge it moved pretty slowly (for a metor/shooting star) across the sky, parallel to the ground, and leaving behind little particles that glowed briefly before fading away. After about 30 seconds, the fireball itself faded away.

Since there was a plane in the sky near where I saw it first, I thought it was a firework or something shot from the plane. Maybe the military testing something (who doesn't like a good mystery?). For some reason, a metor never occured to me.

I've always wanted to see one of these, cool.

According to this site it was on Sunday, which was March 24th. The number of passengers and the originating location of the flight match up too.
