One should keep it simple and precise esp. in the meetings/discussion forums.

Well, that was a smashing article, wasn’t it? I got a new found respect for my job, then I realised it was my guilt of being employed in the first place :D

wotcher !~ …. for a sec, I had a look at your bookmarks and wondered as to when I sent you the link to the Atlantic.com article

it took a long time to sink in – its still possible that both of us perk up and read an article and both bookmark it ( of such in depth analysis combining psychology, finance, economy and evolution of family life ) … so our reading habits still do overlap a little ;). was so impressed with this article, i’ve sent it to my dad for him to read …

still remember the good ol’ days (when I had my teeth … ) and two of us sharing opposite cubicles and passing links to each other. well well well – with technology looks like we can still continue ……….

sadly, I do hope that the nay-sayers are proven right. but just in case, i’m not against buckling up my seatbelt for the coming decade. I had a whole new appreciation for my job after reading that article …

One more thing to include. Website billing. :P

I have to say, your Python code is just damn beautiful. Wonderfully idiomatic. (Err…one little quibble…using “i” to parse the character instructions gave me a little pause — I kept trying to figure out what you were doing with the integer inside the eval() expression. Woulda been better to use a more descriptive name.)

Thanks for tip! As someone new to Django/Python this really helped me.

Pah Thats:-

r = lambda x, a: (x, -1j * a )
l = lambda x, a: (x,  1j *  a )

And the interpreter line of :- for i in instrns: pos = locals ( ) [ i ]( * pos )

which keeps getting eaten by the blog softtware,..

If your using complex arithmetic you can recode the the l() and r() functions as rotations in complex form are equivalent to multiplications.

That and making dirs a dict gives the following:-

dirs =  { 'N':1j, 'E':1, 'S':-1j, 'W':-1j }
rdirs=dict(reversed(d) for d in dirs.items())
r = lambda x, a: (x, -1j * a )
l = lambda x, a: (x,  1j *  a )
m = lambda x, a: (x + a, a )
raw_input()                     # Ignore the grid size
while 1:
# parse initial position triplet
x, y, dir = raw_input().split()
pos = (int(x) + 1j * int(y),dirs[dir] )
# parse instructions
instrns = raw_input().lower()
# Invoke the corresponding functions passing prev position
for i in instrns: pos = locals ( ) [ i ]( * pos )
print int(pos[0].real), int(pos[0].imag), rdirs[pos[1]]

Tested aginst the test vector only.
