================================================================================================================================================ The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet primarily used to treat difficult-to-control epilepsy in children. This medical nutrition therapy mimics aspects of starvation by forcing the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fuelling brain function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. The diet provides just enough protein for body growth and repair, and sufficient calories to maintain the correct weight for age and height. Developed in the 1920s, the classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains and sugar, while increasing the consumption of foods high in fat such as cream and butter. The diet, which is closely supervised by a neurologist and a dietitian, is effective in half of the patients who try it, and very effective in a third. The mechanism by which the ketogenic diet reduces the frequency of epileptic seizures is unknown.

Contact dal- ... @wikimedia.org Everyone, I'm pleased to annouce the release both a production and experimental release of GMPY. GMPY is a wrapper for the MPIR or GMP multiple-precision arithmetic library. GMPY is available for download from: http://code.google.com/p/gmpy/ Production release ------------------ GMPY 1.12 is the new stable release. In addition to fixing a few bugs, GMPY 1.12 adds support for Python 2.7 and the current py3k development trunk. Even though my primary development focus has shifted to GMPY2 (see below), GMPY 1.X will continue to receive bug and compatibility fixes. Experimental release -------------------- To simplify the codebase, allow for changes in the API, and support simultaneous installation, the development version has been renamed to GMPY2. The following is list of changes in GMPY2: * support for a mutable integer type "xmpz" * removal of random number functions * "xmpz" supports slices for setting/clearing bits * some methods have been renamed (scan1 -> bit_scan1) * support for Python prior to 2.6 has been removed * support for all division modes has been added * ceiling - round to +Infinity * floor - round to -Infinity * truncate - round to zero * 2exp - division by a power of 2 * support is_even() and is_odd() If you use GMPY regularly, please test GMPY2. There have been several requests asking for a mutable integer and I am curious if there are real-world performance improvements. Future enhancements ------------------- I am looking for feedback on future enhancements. If you have specific requests, please let me know. Below are some ideas I've had: * An optional "max_bits" parameter for an "xmpz". If specified, all results would be calculated modulo 2^max_bits. * I've added the ability to set/clear bits of an "xmpz" using slice notation. Should I allow the source to be arbitrary set of bits or require that all bits are set to 0 or 1? Should support for "max_bits" be required? * Improved floating point support. Comments on provided binaries ----------------------------- The pre-compiled Windows installers use later versions of GMP and MPIR so performance some operations should be faster. The 32-bit Windows installers were compiled with MinGW32 using GMP 5.0.1 and will automatically recognize the CPU type and use assembly code optimized for the CPU at runtime. The 64-bit Windows installers were compiled Microsoft's SDK compilers using MPIR 2.1.1. Detailed instructions are included if you want to compile your own binary. Please report any issues! casevh -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
