The Portuguese public broadcast service, RTP (the Portuguese BBC) has podcasts for some of its radio shows.
Thanks, kudos/props/wtv for the people (person?) responsible for this. I hope more of Antena’s 2 (music) shows get added soon.
Sadly, it seems that, at least at the moment, it’s only low quality samples (for SOMDESCAPE which is the only show, among those available, that I’m interested in).
PS: what’s up with using WMA and Real instead of making stuff available in (high quality) mp3? That’s lame.

My “Computer Networks” (Redes de Computadores) assignment is writing an HTTP server that implements GET and conditional (if-modified-since) GET with persistent connections.
Here’s the code – Obviously, no guarantees.

This one instead reads the values from a CSV file containing experimental data.
Link to my previous implementation of Simspson’s rule.
import csv
class simpsonCsv:
def __init__(self, filename):
reader = csv.reader(open(filename, "rb"))
xlist = []
ylist = []
for row in reader:
try:
x = float(row[0])
y = float(row[1])
except TypeError:
continue
except ValueError:
continue
xlist.append(float(x))
ylist.append(float(y))
self.len = len(xlist) - 1
self.xstart = xlist[0]
self.xend = xlist[self.len]
self.interval = self.xend / self.len
self.data = map(None, xlist, ylist)
def f(self, x):
for (u,v) in self.data:
if u == x:
return v
print "Bad x value (probably bad n): %s" % (x)
return None
def simpson(self, n):
"Approximate the definite integral of f from a to b by Simpson's rule."
if self.len % n != 0:
print "Error: %d mod %d is not zero but should be." % (self.len, n)
return -1
h = float(self.xend - self.xstart)/n
si = 0.0
sp = 0.0
xk = 0.0
for i in range(1, n, 2):
xk = self.xstart + i*h
si += self.f(xk)
for i in range(2, n, 2):
xk = self.xstart + i*h
sp += self.f(xk)
s = 2*sp + 4*si + self.f(self.xstart) + self.f(self.xend)
return (h/3)*s
filename = "integral_tabela_CO2_csv.csv"
s = simpsonCsv(filename)
print s.simpson(20)
