For ETS's SKLL project, we found out the hard way that Travis-CI's support for numpy and scipy is pretty abysmal. There are pre-installed versions of numpy for some versions of Python, but those are seriously out of date, and scipy is not there are at all. The two most popular approaches for working around this are to (1) build everything from scratch, or (2) use apt-get to install more recent (but still out of date) versions of numpy and scipy. Both of these approaches lead to longer build times, and with the second approach, you still don't have the most recent versions of anything. To circumvent these issues, we've switched to using Miniconda (Anaconda's lightweight cousin) to install everything.

A template for installing a simple Python package that relies on numpy and scipy using Miniconda is provided below. Since it's a common s

Hola!

En este documento van a encontrar información que les va a facilitar la vida en ORGA2 y otras materias, cuando quieran conectarse remotamente a los laboratorios. Espero lo lean y encuentren utilidad en el mismo :).

Decidí dividirlo en varias partes, de forma tal que pueden saltear las que no les interesen.

DISCLAIMER: No me hago cargo de nada de lo que les pueda pasar a sus computadoras o a ustedes por seguir estos consejos. Esto incluye (pero no se limita a): Perdida de acceso ssh a otros servidores, perdida de informacion en su pc local, perdida de tps, ganas de llorar, perdida de cordura y locura espontánea.

This gist lets you keep IPython notebooks in git repositories. It tells git to ignore prompt numbers and program outputs when checking that a file has changed.

To use the script, follow the instructions given in the script's docstring.

For further details, read this blogpost.

The procedure outlined here is inspired by this answer on Stack Overflow.
