Motmot camera utilities introduction — motmot v0 documenta...     Motmot is software for the realtime collection and analysis of uncompressed digital images from a variety of sources. The target audience ranges from anyone needing a simple GUI to record video to the developer wanting to implement a new realtime vision algorithm within an open, plugin-based environment. A primary goal is high throughput and low latency for use in realtime applications. We routinely use these libraries to process data from cameras with data rates up to 60 MB per second (with processing power to spare) on commodity hardware     http://code.astraw.com/projects/motmot/     tags: python webcam motmot's pycamiface at master - GitHub     Python interface to libcamiface     http://github.com/motmot/pycamiface#readme     tags: osx webcam python Whoosh - python search     Whoosh is a fast, featureful full-text indexing and searching library implemented in pure Python. Whoosh was created and is maintained by MattChaput. It was originally created for use in Side Effects Software's 3D animation software Houdini. Side Effects Software Inc. graciously agreed to open-source the code. Some of Whoosh's features include: * Pythonic API. * Pure-Python. No compilation or binary packages needed, no mysterious crashes. * Fielded indexing and search. * Fast indexing and retrieval -- much faster than any other pure-Python solution. * Pluggable scoring algorithm (including BM25F), text analysis, storage, posting format, etc. * Powerful query language parsed by pyparsing. * Pure Python spell-checker (as far as I know, the only one).     http://whoosh.ca/     tags: python bm25 search whoosh Shed Skin - An Optimizing Python-to-C++ Compiler: Shed Skin ...     http://shed-skin.blogspot.com/2010/01/shed-skin-03.html     tags: python c_ Features — execnet v1.0.1 documentation     execnet provides carefully tested means to ad-hoc interact with Python interpreters across version, platform and network barriers.

There’s a big problem, though, which is that PageRank is difficult to apply to the web as a whole, simply because the web contains so many webpages. While just a few lines of code can be used to implement PageRank on collections of a few thousand webpages, it’s trickier to compute PageRank for larger sets of pages.     http://michaelnielsen.org/blog/?p=523     tags: pagerank python buzhug, a pure-Python database engine     buzhug is a fast, pure-Python database engine, using a syntax that Python programmers should find very intuitive The data is stored and accessed on disk (it is not an in-memory database) ; the implementation has been designed to make all operations, and especially selection, as fast as possible with an interpreted language The database is implemented as a Python iterator, yielding objects whose attributes are the fields defined when the base is created ; therefore, requests can be expressed as list comprehensions or generator expressions, instead of SQL queries :     http://buzhug.sourceforge.net/     tags: python PyJudy     http://www.dalkescientific.com/Python/PyJudy.html     tags: python judy Tree-like Constant Database (tcdb)     http://www.unixuser.org/~euske/doc/tcdb/index.html     tags: cdb python C in Python     Cinpy is a Python library that allows you to implement functions with C in Python modules.
