Assuming a household size of 2.58, a US population of about 318 million, and an annual sales figure of about 15 million we can say that the US buys about one car for every eight households every year.

Here is my thought process:

15 million * 21 = 315 million which is about 318 million

so about one car gets sold for every 21 people per year in the US

21/2.58 = 8.139 which is about 8

so about one car gets sold for every eight households per year in the US

Does this logic make any sense? Please leave a comment.

if you run a modified program on a server and let other users communicate with it there, your server must also allow them to download the source code corresponding to the modified version running there.

Creative usernames and Spotify account hijacking

Programming in modules


Spotify supports unicode usernames which we are a bit proud of (not many services allow you to have ☃, the unicode snowman, as a username). However, it has also been a reliable source of pain over the years. This is the story of one time when it bit us pretty badly and how we spent Easter dealing with it.
