The Taste of Synaesthesia
The thought of tetrachromats reminded me of another fascinating perceptual anomoly called synaesthesia, a condition in which senses intermingle and sounds elicit tastes. Here's a Telegraph article on synaesthesia.

How Do You Count Bits?
It's said to be a job interview question, but I've never encountered it. The thing is, after reading a lot of code over the years, I'm surprised by how frequently loops are used by engineers, even in code where speed is critical.
Here's a page that does a good job with the subject:
Counting the Number of Bits in an Integer.

Are We All Colorblind?
"Oh, everyone knows my color vision is different," chuckles Mrs. M, a 57-year-old English social worker. "People will think things match, but I can see they don't." What you wouldn't give to see the world through her deep blue-gray eyes, if only for five minutes.
Preliminary evidence gathered at Cambridge University in 1993 suggests that this woman is a tetrachromat, perhaps the most remarkable human mutant ever identified. Most of us have color vision based on three channels; a tetrachromat has four.
The theoretical possibility of this secret sorority -- genetics dictates that tetrachromats would all be female -- has intrigued scientists since it was broached in 1948. Now two scientists, working separately, plan to search systematically for tetrachromats to determine once and for all whether they exist and whether they see more colors than the rest of us do. The scientists are building on a raft of recent findings about the biology of color vision...

The Check's in the Mail
"We develop an empirical procedure to quantify future company performance based on top management promises. We find that the number of future tense occurrences in 10-K reports is significantly negatively correlated with the return as well as with the excess return on the company stock price."
