I can’t wait until the TSA hears about these! See the full gizmodo article on this here.
Now there’s a full featured iPython implementation for the iPad called Computable. It includes NumPy, SciPy, matplotlib and Pandas. It supports the creation of iPython notebooks that you can then share. This is a handy tool when a typical scientific calculator or spreadsheet just won’t cut it. Recommended.
NB: Sadly, due to Apple’s restrictions on apps and executable code (including scripts) the app is not able to download or sync iPython notebooks. I understand and agree with the restriction from a security standpoint, but it does limit the usefulness of a tool like Computable.
