With the holidays coming up, Bennett Haselton has updated his geek-oriented gift guide for 2014. He says: Some of my favorite gifts to give are still the ones that were listed in several different previously written posts, while a few new cool gift ideas emerged in 2014. Here are all my current best recommendations, listed in one place. Read on for the list, or to share any suggestions of your own.

MojoKid writes "A recent study (PDF) by Richard Clayton at Cambridge University determined that the first letter of a someone's email address directly affects how much spam they receive. As shown in the graph at either link above, email addresses with numbers as their first characters receive even fewer spam emails. The corpus used in the study was 8 weeks' worth of email from the UK ISP Demon Internet, just over half a billion messages, of which 56% was deemed to be spam."

Dr Sabine Begall and colleagues from the University of Duisburg-Essen have discovered that cows tend to point north. The researchers studied deer in the Czech Republic and looked at thousands of images of cattle on Google Earth. The animals tended to face north when eating or resting. "We conclude that the magnetic field is the only common and most likely factor responsible for the observed alignment," the scientists wrote in an article. I guess cows will become the must-have item for long-distance hikers now. Having an edible compass would come in handy if you get lost.

An anonymous reader writes "Michael de Mare's, Confessions of a Recovering Preppie, has been sitting on my desk a long time, for good reason. They say you can't always judge a book by it's cover but in this case, the unintentionally embarrassing front is perfect. Confessions is a painfully ordinary collection of college stories. Michael seems to have a different definition for the word preppie than the good people at Webster or I do. Even though the author specializes in cryptography, he seems unable to decipher any social situation, himself or the code to writing a book worth reading. Click below to see how confusing it gets.

In this week's Disagree Mail, I try to show the range of messages I get. It's not all angry or insane, sometimes it's sent to us for no apparent reason. We start off a little mad, slip into a whole bunch of crazy and finish with someone who has a complaint about racism at his favorite restaurant. Read below to get started.
