My quick talk in 'Write Beautiful Code' HackerEarth Event in Dexetra, Bangalore. Not much text and borrowed a lot of stuff from Hannson and Cormen!

1. PERCEIVING BEAUTY
Sriram V Iyer

2. BORROWING FROM HANNSON
Beauty Leads to Happiness

3. Happiness Leads to productivity
….. So,

4. Beauty leads to Productivity 

5. You can recognize truth by its beauty and
simplicity. When you get it right, it is obvious
that it is right.
- Richard Feynman

7. Perfection is achieved, not when there is
nothing more to add, but when there is
nothing left to take away
-Antoine de Saint-Exupery

8. vs

9. LESS IS MORE (BEAUTIFUL)
l = [ 3, 7, 8, 6, 5, 11 ]
q = []
for i in range( len(l) ):
q.insert( l[i] * 2 )

10. LESS IS MORE (BEAUTIFUL)
def dbl(x):
return x * 2
l = [ 3, 7, 8, 6, 5, 11 ]
q = []
for i in range( len(l) ):
q.insert( dbl (l[i]) )

11. LESS IS MORE (BEAUTIFUL)
def dbl(x):
return x * 2
l = [ 3, 7, 8, 6, 5, 11 ]
q = map( dbl, l )

12. LESS IS MORE (BEAUTIFUL)
l = [ 3, 7, 8, 6, 5, 11 ]
q = [ x * 2 for x in l ]
# Double only odd numbers? …

13. LESS IS MORE (BEAUTIFUL)
q = [ x * 2 for x in l if not (x % 2) ]
VS
q = map( lambda x : x * 2, filter(lambda y : y % 2 != 0, l ) )

14. ATTITUDE IS NO SUBSTITUTE FOR
COMPETENCE
O(n) = log n
VS
O(n) = n log n

15. KNOWING IS EVERYTHING
Insertion Sort (n^2) vs Merge Sort (n log(n))
Computer A 10,000 MIPS vs Computer B 10 MIPS

Sorted
