What I have Learned: In the past two days I have learned that most pictures are saved as JPEG images, but not always, sometimes they are JPG images.  A megapixel is one millions pixels.  A pixel is a tiny dot that, when combined with other pixels, creates an image. Theoretically, the more pixels, the better the image. You want about 250 dpi, dots per inch, which is around the number of dots needed to be invisible to the human eye.  The more dpi, the more ink used when printing your image.

January 6th 2009: Pictures from the Web

Over the break I spent most of my time with my family here at home.
I spent a lot of my time reading. I read Holidays on Ice: Stories by David Sedaris, and I loved it, it was hilarious.

I baked a lot for my family, I haven’t had time recently so it was nice to get back to one of my old hobbies. I made my favorite cake for Christmas, a Sock-It-To-Me Cake.

I also played my violin over the break, though probably not as much as I should have.

All in all, my break was pretty uneventful, but I did enjoy it.
