The names behind the languages

If we're going to continue to spill blood in these language wars, it's important that we all know who our generals are (and who our enemy generals are). Feel free to offer corrections or extensions to the list. C - Dennis Ritchie C++ -  Bjarne Stroustrup Forth -  Charles H.

Venn Diagrams with google charts

I recently had the need to view some data sets as venn diagrams , so I found google's chart api and hacked out a little AJAX application to do so, you can try it out here . And, for the fun of it, a VERY simple Python implementation: import urllib from PIL import Image import StringIO def venn_diagram_url(a, b, c, width=400, height=200): values = [width, height, len(a), len(b), len(c)] values.append(len(a & b)) values.append(len(a & c)) values.append(len(c & b)) values.append(len(a & b & c)) base_str = 'http://chart.apis.google.com/chart?' args_str = 'cht=v&chs=%sx%s&chd=t:%s,%s,%s,%s,%s,%s,%s' return base_str + (args_str % tuple(values)) a = set((1, 2, 3)) b = set((2, 4)) c = set((3, 4, 5)) data = StringIO.StringIO(urllib.urlopen(venn_diagram_url(a, b, c)).read()) Image.open(data).show() Not much to it... But maybe someone will find it useful.
