About Gene Wirchenko

I am a computer programmer / systems analyst living in Kamloops, British Columbia, Canada. I am naturally analytical and like figuring things out. I like reading (mainly science fiction and fantasy) and gaming (mainly board and card games, some RPG).

Puzzle #246: Chocolates

You just bought a box of chocolates for your sweetie. There are fifteen chocolates. Looking down at the contents, you see they are arranged in three rows of five. According to the key, the arrangement of flavours is symmetrical, so the top row is the same as the bottom row, the left column is the same as the right column, and the second columns in from both sides are the same. There are six flavours of fillings: cherry, strawberry, and raspberry (the reds) and orange, lemon, and blueberry.

Given the following clues, what is the arrangement of chocolates?

1) Lemon are not on the corner, strawberry not on the inside, and cherry not next to lemon (not counting diagonal).

2) The number of lemon plus cherry is equal to the number of raspberry plus orange.

3) There is only one blueberry chocolate.

4) Fewer than one-half of the chocolates are red flavours.

5) There are four each of two flavours, two each of three flavours, and one of the last flavour.

Casual?

Is casual good or bad?

I have applied to a local company whose manager claimed to be casual.

He is not. He dresses that way (jeans and T-shirt), but his manner is anything but. He has taken severe pains to impress on me how important sales are to him.

Today, I had a second interview. During it, I called him out on his so-called casualness, and I said he was driven.

He laughed. He said that he owns a lot of expensive stuff. And he wants to continue this.

He is refreshingly blunt. He has a lot of energy. He gets things done.

Casual looks very pale and sickly by comparison.

Puzzle #245: Treasure

You have just found some treasure. In a chest, there are some gold pieces, some silver pieces, and some copper pieces. A “friend” would like to know how much. You tell him that the number of copper pieces is seventeen less than five times the number of silver pieces, that the number of silver pieces is twelve less than five times the number of gold pieces, and that the treasure trove is as small as it could be.

While he is puzzling that out, you beat a hasty retreat muttering under your breath that sharing is for toys and ice cream.

How many of each coin type does your treasure have anyway? (I am just asking.)

Wonderfully Weird

Some people do not like weirdness. Anything that is very different from what they are used to gets labelled as weird and negatively so.

I think that a lot of weirdness is something to enjoy. I follow a Japanese Website SoraNews24. (One of the weird things about it is that it was formerly called “RocketNews24”, but they have not gotten around to changing their URL.)

They write about interesting things in Japan. There are a lot of things in Japan that are weird. Both potato chips and Kat Kit have lots of flavours that do not make it over here. Matcha (green tea) gets added to so many things. And more.

Far from feeling that it is horrible, I feel like I am missing out horribly.

What else am I missing out on, because I decided to avoid something weird?

How about you? What is something unusual that you have tried and ended up liking?

Puzzle #244: Buckets

You have two buckets. One will hold five liters of water, and the other will hold three liters. They have no markings. If you fill a bucket from the faucet, you must fill it full. If you pour from one bucket into the other, you can stop only when the first bucket is empty or the second bucket is full. You can also discard all of the water in a bucket.

How can you end up with four liters of water in the five-liter bucket?
