Her Royal Highness, Princess Precious Petunia Picky-Eater of That Comfy Chair is the proud owner of twelve toy mousies. Some are white, some are brown, and some are red. She has bitten the tails off exactly one-half of them. There is at least one mousie in each of the six, possible combinations of colour and tail(less)ness. She has more white mousies than red mousies. The number of mousies of each colour is prime. If she has two tailless, brown mousies and more tailed, white mousies than that, how many tailed, white mousies does she have?

In Promotion Again, I wrote of a possible employment opportunity that I had with Ride North America. (If you are a motorhead, why not check the site out?)
I have just started part-time with RNA.
RNA has a much more elaborate Web site than I do.
I have been blogging for nearly three years now. I have gotten comfortable with my routine — probably way too comfortable — but WordPress is capable of so much more. Now, I really get to move out of my comfort zone and find out just how much.
Oh, well. I have said for years that I learn best under actual combat conditions. Now, I get my wish.
Such an opportunity. It is both great and rather scary. Many great opportunities are.
With any luck, those alligators will never know what hit them. The swamp is getting drained.
Wish me luck?
http://www.computerworld.com/article/3025882/security/why-wont-we-help-users-create-good-passwords.html has “After five rounds of rejected new passwords, re-entering the password and giving him another chance to choose an alternative, I patiently explained that our password-complexity requirements would not allow the password to have two numbers next to each other.” followed a bit later by “He said, ‘OK, great. I don’t know why it wouldn’t take my new password — 4 and 6 aren’t next to each other…'”
The issue: In a proposed password of “badpassword46”, the 4 and 6 are next to each other in the password, but not on the keyboard. The rule that was being applied was using the first meaning, but the user took the second meaning.
When writing instructions for others, making sure that the instructions are unambiguous is both a good idea and surprisingly difficult to do.
Suppose we have a group of cat lovers who share cats. There are five cats to be shared, and everyone has three of the cats. There would be ten people, and each cat would be shared by six people.
Orders from our feline overlords are that, instead, we have seven cats, and everyone has four of the cats. How many people are there? How many people share each cat? (Or if you prefer, how many staff does each cat have?)
