Compare two lists?

list(set(b).difference(set(a)))

done

#!/usr/bin/python

winners = []

for a in range (100, 999):
    for b in range (100, 999):
        test = str(a * b)
        if test == test[::-1]:
            winners.append(int(test))

print max(winners)

#!/usr/bin/python

def prime(n, start):
    factors = []
    while (n % start != 0):
        start = start + 1

    factors.append(start)

    if n > start:
        factors.extend(prime(n/start, start))

    return factors

print max(prime(600851475143, 71))

#!/usr/bin/python

counter = 0

def fib(n):
    result = 0
    a, b = 0, 1
    for i in range(n):
        a, b = b, a + b
	if a < 4000000:
            if a%2 == 0:
                result += a
        else:
            return result

print fib(100000)

result = 0

for i in range (1, 1000):

print result

Well yeah not immediately great.

I thought I`d start small by synchronizing Tomboy with a directory. Fail. Running Conduit from the command line revealed the answer – Incompatible Tomboy version. Aha thinks me I`ll upgrade Tomboy – there is bug about the version thing logged on launchpad currently. So, download the current version 0.11 the bleeding edge development one.

Building it fails everytime complaining with: Mono.Cairo.dll missing. Now I wasn’t able to fix this on purpose. I ran

sudo apt-get build-dep tomboy

Which did the right thing fixing the strange missing but installed dll.

Back to Conduit. Now running the spanking new Tomboy I fired up the sync again.

Fail.

Same error this time. So its not Tomboy thats the issue. So as I`m planning to hack around with this anyway I checkout the latest code from subversion using the following instructions: Build Instructions. As its prebuilt from subversion you can just run it without compiling. It all works a treat now. Now for playing.

Thanks John Carr for your speech at LUG Radio for pointing this cool bit of kit out.
