<p style="color: grey"> Python recipe 511444 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/network/">network</a>). </p> <p>Courtesy of Yahoo finance, it is possible to bulk download historical prices data. This script, borrowed from pycurl retriever-multi.py example, fetch series for several tickers at a time. It uses urllib to fetch web data, so it should work with a plain vanilla python distro.</p>

<p style="color: grey"> Python recipe 413404 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/distributed/">distributed</a>). </p> <p>It's only a matter to put together Reportlab to generate a pdf file on the fly and Cherrypy xmlrpc filter to serve it as an XML/RPC binary object (base64-encoded).</p>

<p style="color: grey"> Python recipe 410662 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>Since the excellent &lt;a href="http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/366178"&gt;fast prime number list generator&lt;/a&gt; recipe, it's simple to implement a function to check if its input it's a prime number.</p>

<p style="color: grey"> Python recipe 410663 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>primepow(aNumber) finds the prime number P and power N of aNumber such that aNumber = P^N.</p> <p>The implementation is heavily borrowed from Art Owen &lt;a href="http://www.csit.fsu.edu/~burkardt/cpp_src/oa/oa.html"&gt;Orthogonal Arrays Library&lt;/a&gt;. It requires the &lt;a href="http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/410662"&gt;isprime()&lt;/a&gt; function.</p>

<p style="color: grey"> Python recipe 347210 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/distributed/">distributed</a>). </p> <p>This recipe shows how to build an xmlrpc multithread server that exposes a Pyro remote object as a web service. Be careful to the remote object state: two different ways (a global and a thread local) are shown.</p>

<p style="color: grey"> Python recipe 259177 by <a href="/recipes/users/631476/">gian paolo ciceri</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>The algorithm to compute the CRC is described in the ISO 3309 standard. The generator polynomial is x64 + x4 + x3 + x + 1. Reference: W. H. Press, S. A. Teukolsky, W. T. Vetterling, and B. P. Flannery, "Numerical recipes in C", 2nd ed., Cambridge University Press.
