6. “Someone who is excepPonal in their role is
not just a liWle beWer than someone who is
preWy good,” he argued when asked why he
was willing to pay $47 million to acquire
FriendFeed, a price that translated to about $4
million per employee. “They are 100 Pmes
beWer.”
‐Mark Zuckerberg

7. 1. They are fast.
2. They write readable code.
3. They write modular code.
4. They write re‐usable code.
5. They can use the right tool for the right problem.
6. They connect the dots.
7. They think of news ways to solve old problems.
8. They are mePculous ‐ they cover all cases ‐ they worry
about security, scalability, internaPonalizaPon, privacy
9. They can lead teams of developers.
10. Did I menPon they are fast.

10. FindMeASpot ‐
App to help you find a place to park

11. Knowing what you want
Minimum:
Tells you with a message if there is a spot to park in, at a parking area that
you specify.
Other Features:
Detects local parking areas that have free spots.
Suggests other parking areas if all the nearby ones or the one that you
specified is taken
Tells you how many spots are leK.
Tells you the price per hour.
Tells you the exact locaPon of the spot.
Tells you if the spot will fit your car
Tells you the safety raPng of the area

15. Data that you need:
1. Parking area ‐ name, locaPon, max number
of cars
2. Cars currently in the parking area
3. What else?

16. 3 Simple Programming Concepts

17. DeclaraPons

18. cars = 0
parking_area = [‘volkswagen K542, Mercedes
P4343, etc’]
parking_area_info = [name:‘Joes parking spot’,
locaPon:‘46th and 8th’, max_cars:20]

19. Loops

20. for car in parking_area:
cars = cars + 1

21. CondiPonals

22. if cars < 20:
RingTheAlarm(“Found a parking spot”)

23. Evaluate ImplementaPon for Different features

24. 3 Not So Simple Programming Concepts

25. FuncPons

26. RingTheAlarm(string):
print string
sendToPhone(string)
playRingTone(“success”)

27. Objects + Classes

28. Car():
color
license
make
type
VW = Car(blue, “K567”, VW,
4wheel)

29. Data Structures

30. Hash:
Organize things via a certain funcPon
Queue:
FIFO
Stack:
FILO
Tree:
Family Tree/Org Chart
Linked List:

34. The Mythical Man‐Month

35. List of things that piss programmers off
1. Changing requirements
2. Incomplete requirements
3. Indecision about requirements

36. Requirements
Pseudo Code
Test Cases

37. Processes ‐ Agile/SCRUM, Waterfall

40. Checklist for EvaluaPng an Idea
1. CRUD ‐ Create, Read, Update, Delete
2. API Dependencies (3rd ParPes)
3. CS heavy ‐ Search, Relevance, RecommendaPon, Filtering, New vs Known
4. Operate at scale ‐ users, data, concurrency
5. Number of plazorms

41. Audience Examples

42. What’s next?
Details of making a simple web app
How to work in a team
More about the soKware development process
More about fundamentals of programming
More about plazorms and web stacks
