Gets as input a file dumped from an oscilloscope that understands CPRI format. File should be csv with each line having a time and data value. Data values look like 'K28.5+' or 'D16.2-" or similar. This script finds some info from that file and prints it such as HFN and BFN. #python #cpri #bitarray

A variation of the LOVE calculator. There are three versions of the actual calculator, they were provided as answers to my question at Quora: http://www.quora.com/How-do-I-sum-numbers-in-lists-by-pairs-until-just-one-pair-is-left. To try them out, replace the function call on line 66. #haskell

This simple code snippet shows how interpolating can be done in C using signed integers. The for() loop determinest the range to interpolate from. In this case -100 to +100. For loop is here just to work as an example. 12th line is were the work is done. 256.0 is the top end of the range while 201.0 is the number of values in the list to be inte…
