Compute total size of git-annexed files with only one local copy
# This script computes the total size of git-annex files with only a single local copy.
# It's useful to figure out how much data will be used if all the files were to be archived.

Jupyter notebook post hook save to rename untitled notebooks to `YYYY-MM-DD_untitled-N.ipynb`
# This file should be put in ~/.jupyter/
# New notebooks will be renamed to YYYY-MM-DD_untitled-N.ipynb instead of Untitled.ipynb
# Please be aware that this code has **NOT** been tested extensively, I wrote it rather quickly,
# and thus your notebook might be deleted by accident.

Example with PyMVPA and joblib to run nested classification in parallel
from mvpa2.suite import *
# increase verbosity a bit for now
verbose.level = 3
# pre-seed RNG if you want to investigate the effects, thus
# needing reproducible results
#mvpa2.seed(3)
# we import Parallel and delayed from joblib to run in parallel
from joblib import Parallel, delayed

### ABOUT: See: http://gist.github.com/366269
### Runs rsync, retrying on errors up to a maximum number of tries.
### On failure script waits for internect connection to come back up by pinging google.com before continuing.

### Usage: $ ./rsync-retry.sh source destination
### Example: $ ./rsync-retry.sh [email protected]:~/* ~/destination/path/
