The most recent Weather Brains episode 424 is now on YouTube and features guest Josh Wurman, the reknowned severe weather research scientist. Dr. Wurman tells some interesting and amusing stories about doing field research on severe weather of all kinds, talks about why the El Reno tornado on 5/31/2013 became a storm chaser killer, and he gives viewers insight into some of the current research on tornadoes. One thing I didn't know: tornadoes occur where there are competiting warm air masses like along a dry line where on one side there is a warm, moist air mass while on the other side there is a warm, dry air mass.
*The subject of this post is a line spoken by one of the guests at the 2:03:03 mark.
The best way to explain how to choose a good password is to explain how they're broken. The general attack model is what's known as an offline password-guessing attack. In this scenario, the attacker gets a file of encrypted passwords from somewhere people want to authenticate to. His goal is to turn that encrypted file into unencrypted passwords he can use to authenticate himself. He does this by guessing passwords, and then seeing if they're correct. He can try guesses as fast as his computer will process them -- and he can parallelize the attack -- and gets immediate confirmation if he guesses correctly. Yes, there are ways to foil this attack, and that's why we can still have four-digit PINs on ATM cards, but it's the correct model for breaking passwords.
Brad Humphreys sent along a call for papers for North America Association of Sports Economists sessions at this year's SEA meetings in Atlanta Nov. 22-24. Note that a session on the teaching of sports econ is of particular interest. Here's the CFP
The North American Association of Sports Economists (NAASE) is again organizing sports economics sessions at the Southern Economic Association (SEA) conference. The conference will be held November 22-24, 2014 in Atlanta, Georgia. The basic format of the NAASE sessions will be the same as in the past. I hope to have several complete sessions to take to the SEA organizers to assure us of a good room and good session times.
*Deadline for submissions is April 1.*
We are trying to put together a session on teaching sports economics. Anyone with a paper idea that would fit a session on teaching sports economics is especially encouraged to submit their paper.
If you have a sports economics paper you would like to present in Atlanta, please email Dennis Coates (see below for contact information) a title and full contact information including post and email addresses. Your submission must contain full contact information for all co-authors.
Here is the contact information for the session organizer:
Several viewers have been asking why the roads hit by the snow storm in Wisconsin seemed to be in better condition than those in Minnesota.
“As soon as we hit the bridge, it was wet,” Kristine Glenna said about her drive from Woodbury to Hudson. “We keep being told that it’s too cold for chemicals to work, and it’s going to be like this for several days, but obviously something’s working in Wisconsin.”
Woodbury is in Minnesota, Hudson is in Wisconsin right across the St. Croix River. Why might this be?
Todd Rehnelt, St. Croix Highway Department’s assistant patrol supervisor, says there is one major difference between the neighboring states.
“We manage the road system for the state, whereas the state of Minnesota manages it themselves,” Rehnelt said. “The process itself is about the same.”
The Minnesota Department of Transportation is responsible for 5,000 miles of roads in the metro alone, while it’s up to the individual counties to plow in Wisconsin.
Here is the full story. Thanks to Gary Miller for the link.
Jason Berkowitz, Assistant Professor of Finance at St. John's, is putting together a proposal for a session or two at this year's Southern Finance Association Meeting in Key West, Fl (a location that, to this northerner enduring another honest to goodness blizzard, sounds really, really appealing). Here's the skinny on what Jason is looking for.
Hello everyone, I am reaching out to you all as I would like to organize a sports betting session (possible two) at the Southern Finance Association Annual Meeting in Key West, Florida from November 19-22. If you have a paper you would like to present please e-mail me your abstract or completed paper by February 25th <firstname.lastname@example.org> so I can have a few days to put the strongest possible proposal together.
But wherever the NCAA's rulebook has a say, the merely inane will inevitably be topped. And so we present to you this anonymous-sport classic, which if the NCAA is ever granted a tombstone, will surely be etched upon it:
May 10, 2013
Violation: Three current student-athletes received food in excess of NCAA regulation at a graduation banquet. The three had graduated from the school but returned for an additional season of competition. The players were provided pasta in excess of the permissible amount allowed. Resolution: The three were required to donate $3.83 each (the cost of the pasta serving) to a charity of their choice in order to be reinstated. The department provided rules education to applicable athletics department staff members.
The first song I learned to play all the way through on guitar was Rush's Xanadu. Then again, I was about 15 or 16 years old at the time, not 7 like this burgeoning drummer playing Rush's Tom Sawyer - impressively too.
