Obfuscated urls stink. Being able to hover over a link and see where it goes is a tremendous feature of any modern browser. Use unshorten on your command line to see where they go. The project is at github. Put unshorten.py somewhere on your path and make it executable …
I've been experimenting with PLY and was encountering an obscure
error that was surprisingly Google-resistant. I've been building up a language
and a REPL to interpret commands. When trying to parse a statement spanning multiple lines,
I would get an error {TypeError}Can't convert 'type' object to str implicitly.

During a Milwaukee Bucks broadcast on February 11, John McGlocklin mentioned something to the effect of "the first team to get to 100 points usually wins." Intuitively, this makes some sense. If you're the first team to a given score, you have the lead at that point. 100 points is …
$ pip install opencv never seems to work quite right. If you get the message

There are a handful of answers strewn across the internet about installing OpenCV's Python bindings, but none …
I've pushed some changes to the pypeline repository, adding basic stacking functionality. There isn't any registration, it only takes the median of each channel (R, G, B) for each pixel. It's currently way slow, but I suspect there is substantial room for improvement there. Wrangling NEF files has proven more …
Inspired by this post at DataGenetics,, I implemented a quick-and-dirty script in python to test it out. The first takes an input image and iterates over it pixel by pixel, splitting it into two output images. Ideally, the outputs are randomly assigned, so it is impossible to recover the original …
Apparently PIL, and therefore Pillow, do not support Nikon RAW (.NEF) files. From what I can tell, my camera shoots RAWs in a 14-bit grayscale format. With the help of nefarious, I've found a way to get the image data out of my RAW files. Images coming soon!
I'm using Linux Mint 15 ("Olivia") for my pypeline development - and ran into a little difficulty
right off the bat getting pillow installed. Virtualenv and Virtualenvwrapper are pretty much a must-have if you're
developing multiple projects, and pip install pillow was failing with messages like
Python.h: No such file …
Since I plan on taking quite a few night sky pictures, I'd like to automate the process as much as possible. The project is hosted on github here. Right now it's essentially empty, but eventually features I'd like it to have:
