The three units of weight I’m familiar with are pounds, kilograms, and stone. For me, stone is the odd one. I’ve heard it used in Britain and it’s completely baffling to me, often requiring that I whip out a calculator to see what “14 stone” really means. Better, I could write code that converts between pounds, kilograms, and stone, which is the goal of this month’s Exercise.

I recently updated my Wambooli website’s front page to show only recent blog posts. I don’t regularly maintain the Wamblog any longer, so it was disappointing for me to see “recent posts” from ages ago. Therefore, I did a little coding to ensure that only recent posts appear or nothing.

I remember the first time I heard the puzzle: If you’re paid a penny on the first day, doubled on the second day, and doubled every day after, by the end of the month you’d be a millionaire many times over. This concept is mind boggling.

I would guess that most beginning programmers can deftly craft a loop that outputs sequential integer values, say from 0 to 100. In fact, this is the type of code I write whenever I learn a new language. I asked myself, “Can I write a loop to output values 0 to 100?” Usually in no time, I’ve constructed such a program. Simple.

I enjoy playing number games. I’m not good at it, but I enjoy playing them. Recently such a game piqued my curiosity enough to consider it for my monthly C For Dummies exercise: 21

After a few intermediate to advanced Exercises, I decided to try something that’s a little easier this month. Still, even if you’re a pro, it helps to pull back and try something basic just to see what you can do with it.

I enjoy reading about and studying mathematics. One of my favorite books is A History of π. I’ve used this book to inspire my Pi Day (March 14) programs. It’s fascinating stuff.

This month’s Exercise may seem like a repeat of the Exercise “We Have a Winnah!” from July of 2013. It’s not.

Like many innocent and silly math games, No Nines is nerdy to play but fun to code. The game works like this:

One of the many, useful tools a programmer must have is a hexdump utility. The utility consumes a file’s raw bytes and outputs them in a human-readable manner. By examining the dump, you can determine if file contains the proper data in the correct format, as well as do other interesting, useful, and technerd things.
