Structured grid operators

I have finished the first draft of some structured grid operators, using MATLAB. The idea is to create a very simple, minimalist set of functions that can be used to work with structured grids. For example, there are tools to average grid points to reduce the size of a matrix to match anther (like you need to do to get velocity on rho-points). There is a very general tool for extracting isosurfaces. There are a few bonus tools for working with the s-coordinate used in roms.

Take a look.

Unison File Synchronizer

A nifty alternitive to the checkout/checkin sequence required by rsync the Unison File Synchronizer. Be careful not to confuse this with the panic newsreader unison, which comes up first if mac os x is added..

Getting MacPython and TK working together

Basically just go here to get all your Python Stuff

First you need to install Tcl/Tk Aqua, then you can install the "official unofficial" MacPython 2.4.1. This version has all the goodies already installed, notably (for me) Tkinter and readline.
