I am pleased to announce the release of +Fatiando a Terra v0.2!

This release includes many new features and improvements. Read all about it in the linked blog post. The main addition is a new framework for solving geophysical inverse problems. It aims greatly simplify the process of building new inversion solvers.

Many thanks to +André Ferreira , +Vanderlei Coelho  and Henrique Bueno dos Santos, who are first time contributors to the project!

A couple of weeks ago I was at the +ScipyConference giving a presentation about my open-source geophysical modeling package +Fatiando a Terra. The video of this talk is now on YouTube!

There are some code examples of some of the functionality. If you're interested in learning more, go to http://www.fatiando.org or contact me directly!

The slides for this talk (as well as all the source code) is on a +GitHub  repository: https://github.com/leouieda/scipy2013

As promised, a blog post about my first publication! As I've mentioned before, the results were obtained using the dev version of +Fatiando a Terra. The code will be released with version 0.1 in the near future. The supplementary material is all on +figshare and the code is hosted on +Bitbucket

For a while we've been thinking of opening up the fatiando.org domain to more than just the +Python package "fatiando". We now include some other open-source software (like Tesseroids for gravity modeling in spherical coordinates), lecture notes, slides, and other content. All free and open source! Check it out and let us know what you think!

I've been designing a new inverse problems framework for +Fatiando a Terra that is loosely (shamelessly) inspired by the scikit-learn (http://scikit-learn.org/) object-oriented API.

It's a work in progress but looking pretty good so far. I'd love some feedback, please!

New post on the +Fatiando a Terra a Terra blog!

TL;DR: Learn to program so you can learn theoretical concepts hands-on. and gain a deeper understanding them.

Inspired by this post (http://www.agilegeoscience.com/journal/2011/9/28/learn-to-program.html) by +Matt Hall

+Fatiando a Terra version 0.1 has been released into the wild internet!

The blog post includes an example if a toy tomography problem. It is an +IPython notebook and can be downloaded and executed!

Go try it out and be sure to let me know what you think!

Finally my first paper is out on Geophysics!

Uieda, L., and V. C. F. Barbosa (2012), Robust 3D gravity gradient inversion by planting anomalous densities, Geophysics, 77(4), G55-G66, doi:10.1190/geo2011-0388.1.

You can get it at the Geophysics website (http://dx.doi.org/10.1190/geo2011-0388.1) or download it from my personal website.

This is the result of the work done during my Masters. The code developed for this paper is already integrated into +Fatiando a Terra and will be part of the next release (0.1)! It is part of the +Python package and there is also a command line program that runs the inversion, for those who don't want/need to mess around with Python.

I'll make a blog post about this soon, with some code samples and nice 3D plots!

Also check out the supplementary material on +figshare:

A great review of how the +Python setuptools works and the current issues with Python packaging and new tool pip.
I encountered the issue with binary distributions when I tried to package the 0.0.1 beta of +Fatiando a Terra. Of course, this didn't work even under Windows, but that is f2py's fault.
The way I found around this was to implement everything in Python and make optional Cython modules that are compiled if Cython is available at installation. Hopefully this makes it easier to get +Fatiando a Terra working in the next release (0.1) due soon!
