# Puzzle #55: Digits

Consider the digits from zero to nine. One of these digits has a property that the others do not. It has nothing to do with any arithmetic properties.

Which digit is it, and why?

(This is the sort of puzzle that could have multiple answers. I will accept any reasonable answer.)

# Automation: It Works Until It Doesn’t

Automated systems are wonderful. They can save a lot of time, money, and what-have-you(-that-you-want-to-keep).

Unfortunately, when they do not work, there is a big, big snarl.

For an example, do you bank in person or using an ATM?

I use the former. I have caught errors of my credit union transferring to the wrong account as balances do not look right when I do my banking the following week. Because the teller and I are both human, we deal with the error very quickly.

Try cleaning that up with an automated system. You can talk to an automated system, but it will not do much good.

Why are so many people in a hurry to get rid of people?

# Odd Language #51: A Unique Pronunciation

An odd word from _Archform: Beauty_ by L. E. Modesitt, Jr.: “uniquery”.

The term is never defined, but from context, it might be a store that sells unique items or near-unique items.

The issue: Even knowing the above, it is very hard for me to resist thinking of it as being pronounced “you-knee-query” (instead of the apparent “you-nique-ery”).

I think I have previously mentioned that I think that L. E. Modesitt, Jr. is a very good author. Just to be sure: I think that L. E. Modesitt, Jr. is a very good author.
