Winter Bash 2017

I was only able to get 13 hats for Stack Exchange Winter Bash 2017. Unfortunately, I had forgotten that it would end today, so I was not able to get images of me wearing the hats. You’ll just have to trust me that I really got the hats below.

Gift from Academia

Last December 12, 2015, I received an e-mail from telling me that as “one of the top users in Academia,” I was entitled “to a little box with some new swag designed for [my] community.” (More information can be found here.) I filled up the form the same day. Yesterday I received a registry notice from the local post office asking me to go there and pay 112 pesos to claim a package. (It wasn’t explained to me why I had to pay them to get my mail.)

I paid the fee and got the package, a plastic envelope containing a T-shirt and three sets of 2 stickers, each set in its own little cardboard envelope.

According to the shipping label, the package was sent on January 13, 2016, the contents weighed 12 ounces, and the value of the contents was US$ 3. Thanks, Academia!

Gift from MathOverflow

Last June 17, 2014, it was announced on MathOverflow Meta that “established users” that “have actually made (and will hopefully continue to make) valuable contributions to this site” would be given gifts if they ask for them. I filled up the form and waited, but I wasn’t sure if they would give the gifts to someone outside the U.S.A.

The goods arrived yesterday. I got a mug, an XL-size T-shirt, and three stickers in a box that was a little too big for the goods. The commercial invoice states that it was sent last October 21, 2015. I was very surprised that it took only around 7 days to reach me. (Most packages sent to me from the U.S.A. take a few weeks to a few months to reach me.) The invoice states that the mug has a value of US$ 5, the T-shirt is worth US$ 3, and each sticker is worth US$ 0.25. Thanks, MathOverflow!
