[Python Cookbook] Constraint-based Sudoku Solver [ 01:33 Uhr ] [ 117 Worte ]

[Python Cookbook] Constraint-based Sudoku Solver «This code uses the constraint package to solve sudoku puzzles. It's designed to be flexible, though i've only tested it with 9x9 puzzles with 1-9 as possible values. In theory it should be able to solve puzzles of different sizes comprised of letters or symbols instead of numbers.»

[Marko Samastur] Python on series 60 «I knew it exists, but I haven't looked into Python on series 60 until yesterday and I wish I did so sooner. My mind is just flooded with ideas of what to do and I can easily see myself wasting lots of time playing with it.»

Gustavo Sverzut Barbieri: GStreamer, Python, OpenGL and Applications that rocks! [ 10:35 Uhr ] [ 210 Worte ]

Today I attended Thomas vander Stichele GStreamer 0.10: Past, Present and Future presentation. First of all, Thomas did really great, nice talk, nice slides, live coding using python and cool applications.

What really caught my attention was demonstration of Elisa, a Python application that uses OpenGL and GStreamer to provide an incredible interface, responsive, beautiful and organic. There is no screenshot online, but worth the pain to download, install and try it!

Other applications that were demonstrated:
  • PITIVI: non-linear video editor.
  • Togra: it provides easy-to-use and fast OpenGL scriptable in Python, one example used it to show video textures, some balls bouncing with the surface being a video from GStreamer.
Also, he demo'ed how 0.10 is responsive to seeks and instantaneous paused-playing transition... these were horrible before. He said the core was reworked to be thread safe, memory leaks and dead locks. Great work!

[Python Cookbook] Automatic recursion arguments [ 00:46 Uhr ] [ 106 Worte ]

[Python Cookbook] Automatic recursion arguments «Makes it easy and stable to recurse the current function when only selected arguments have to be changed. No more mixup of argument positions/names. No more forgetting. Makes it easy as well to delay/repeat/serialize function calls ad-hoc.»
