License plate readers
do exactly what the cop on patrol did using a paper list and the Mark
1 eyeball. Except that all the information was kept forever. If we
eliminate the “kept forever” bit, have we restored privacy to
pre-Big Brother levels?
Associated Press
reports:
A
Michigan lawmaker is planning to introduce legislation to regulate
the use of devices that photograph license plates.
Rep.
Sam Singh says his upcoming bill would require police agencies to
delete license plate records from data systems within 48 hours unless
the record is evidence of specific criminal wrongdoing.

portion of my students are there on the GI Bill. (All ten parts are
available now.)

Part Series examines rising costs and consequences of higher
education
The
Tuition is Too Damn High is a 10-part series that will run in
Wonkblog over the next two weeks exploring the causes and
consequences of — and potential fixes for — the skyrocketing
costs of higher education. This is part one.” By Dylan
Matthews
“But if the upfront
price of college is rising much faster than earnings, how are more
and more families managing to pay for it? In large part, by going
into debt. The total student loan burden now
exceeds $1 trillion, with two-thirds
of the class of 2011 taking out loans and over
40 percent of 25-year-olds still in student loan debt. About
two-thirds
of borrowers have debt loads under $25,000, but that means one-third
are looking at more than $25,000 in debt. All in all, 17
percent of borrowers are at least 90 days delinquent on their
payments. Maybe that’s smart; college is a good investment, as
we’ll see in more detail in later segments, and some
have even suggested
that there might actually be too little student debt. But
that debt is a new and major part of our financial world now.”
For my Math students as
we go through factorization: You have it easy! Of course they could
have simply generated a huge list of large Primes by multiplying
smaller primes... Just saying...
Did
the NSA secretly make a major math breakthrough?
In a recent
story about the U.S. National
Security Agency’s controversial Internet surveillance
operations, the New York Times reported that “the agency
has circumvented or cracked much of the encryption, or digital
scrambling, that guards global commerce and banking systems.”
The bolding is mine,
because if in fact the agency did crack the encryption schemes used
for bank transactions (the Times is somewhat unclear on that
point), then in doing so it may have solved a math problem that has
long puzzled cryptographers and number theorists alike.
The problem in question
is that of integer factorization.
For all my students:
