No longer merely a\nresearch project, PyPy is now suitable for production use. We are working on\nimprovements on calling into C libraries and generally integrating with the\nexisting Python extensions ecosystem.\n\nWe will give an overview on how the tracing Just-in-Time compiler works in\nPyPy. From there, we will then focus on what the PyPy project has achieved,\nparticularly in the past two years:\n\n * most Python benchmarks run much faster than with CPython or Psyco\n\n * the real-world PyPy compiler toolchain itself (200 KLocs) runs twice as fast\n\n * already supports 32 and 64bit x86 and is in the process of supporting ARM\n\n * full compatibility with CPython (more than Jython/IronPython)\n\n * full (and JIT-ed) ctypes support to call C libraries from Python\n\n * supports Stackless Python (in-progress)\n\n * new \"cpyext\" layer which integrates existing CPython C extensions\n\n * an experimental super-fast JIT-compilation of calls to C++ libraries\n\nWe want to reserve time for discussing potential future work like SWIG and/or\nCython compatibility and other areas brought up by the audience. There are\nmany interesting details that can be explored further; we will focus on the\npoints the audience is most interested in.\n\nFor more info:\n\n * [](\n\n * Our blog: [](\n\n * Eureka program: [](\n\n_Eurostars Eureka is our funding source since 2009. It is a cross-European\nfunding collaboration that targets small firms which produce research._\n\n", "quality_notes": "", "copyright_text": "Standard YouTube License", "embed": "<object width=\"640\" height=\"390\"><param name=\"movie\" value=\";hl=en_US\"></param><param name=\"allowFullScreen\" value=\"true\"></param><param name=\"allowscriptaccess\" value=\"always\"></param><embed src=\";hl=en_US\" type=\"application/x-shockwave-flash\" width=\"640\" height=\"390\" allowscriptaccess=\"always\" allowfullscreen=\"true\"></embed></object>", "thumbnail_url": "", "duration": null, "video_ogv_length": null, "video_ogv_url": null, "video_ogv_download_only": false, "video_mp4_length": null, "video_mp4_url": null, "video_mp4_download_only": false, "video_webm_length": null, "video_webm_url": null, "video_webm_download_only": false, "video_flv_length": null, "video_flv_url": null, "video_flv_download_only": false, "source_url": "", "whiteboard": "", "recorded": "2011-07-13", "added": "2012-08-30T21:02:34", "updated": "2014-04-08T20:28:27.867" }
