Real-world benchmarking of key/value stores
I’ve been involved with some heavy data mining, storage and analysis. We’re currently using MongoDB (not my choice) but I’m considering moving to something faster. Queries on large collections are taking a long time, even with indexing. I’m sure I can optimize it further, but it might still be a problem later. Thankfully, Pete Warden has done some legwork and benchmarked a few other key/value stores, namely memcached, Tokyo Tyrant, Redis with MySQL as well.

PASW Statistics Data File Driver Guide
PASW is the old name for SPSS. The statistics program outputs a .sav file, what is essentially a file-based database. This guide contains instructions on how to use a driver to access data within the SPSS output file. The driver exposes an ODBC source for data access. It may be possible to use SqlAlchemy to access that source. If so, one can read and write SPSS data files from Python.

Nick Brandt – A Shadow Falls (2005-2007)
“Few photographers have ever considered the photography of wild animals (as distinctly opposed to the genre of Wildlife Photography) as an art form. The emphasis has generally been on capturing the drama of wild animals IN ACTION, on capturing that dramatic single moment as opposed to simply animals in the state of being.
I’ve always thought this something of a wasted opportunity. The wild animals of Africa lend themselves to photographs that extend aesthetically beyond the norm of 35mm-color telephoto wildlife photography. And so it is, that in my own way, I would like to yank the subject matter of wildlife into the arena of fine art photography. To take photographs that transcend what has been a largely documentative genre.” – Nick Brandt
