Here are some simple lessons I learned today while working on profile pages on Posterous.
- Always set a minimum size
- Image resizing can easily be extended so you can do square cropped thumbnails using mini_magick.
- Developing Rails apps on Windows sucks. An obscure bug in attachment_fu running on Windows -- would not have known how to fix this if it were not for the Google.
The power of open source + Google in action. It is an exciting time to be alive.
