I won't do it (if I have a choice)
jnaapti

I won't do it
If you are planning to startup, you don't have a choice
– unless you have a lot of money
Supply is much lesser than demand
See the opportunity?!

Rapid change in Technology
Android/iPhone was not
around in 2005
How long will Android be
around?
Things are getting outdated
at an exponential rate
It's getting harder to find
people with the skills you
need

I can't do it – aka
Can Everyone Program?
jnaapti

18.
http://jnaapti.com/
Does everyone need to learn to program?

19.
http://jnaapti.com/
Heard of 'Calculator Science'?

20.
http://jnaapti.com/
Everyone can learn
some learn faster than others
some have in-born abilities
some have a natural knack, but
“EVERYONE CAN”

21.
http://jnaapti.com/
It's like learning to swim, or learning to drive a
car, or learning music

22.
http://jnaapti.com/
You have all it takes
You have access to a lot
of the tools that big
corporations use for free
You have computing
power available cheaply
You have access to a lot
of the data for free

23.
http://jnaapti.com/
What do I need then?
All you need is a little intelligence and a lot of
perseverance and you are on your way!

What's in it for me?
Scrabulous case study
Built by 2 young chaps from Kolkata
Both were in their early 20's when
they built it
One was still in college.
500,000 users daily – back in 2008,
25,000$ in ad-revenues per month
These days lots of apps being built by
college under-graduates.
If they can do it, you can do it too!

Getting Inspired
Youtube Stats
100 hours of video are uploaded to YouTube every minute
Free Data Sets
Common Crawl – 10s of TBs of data available for free
AWS Public Data Sets
Cisco’s Internet Business Solutions Group predicts some 25
billion devices will be connected by 2015, and 50 billion by
2020.

Guidelines to Get Started
jnaapti

31.
http://jnaapti.com/
Mimic the Geeks
Characteristics of Geeks
Infinite thirst to learn, they are all life long learners
Curiosity drives their learning
Their observation skills are commendable
Learn from people and websites out there
Always experimenting – their knowledge is not just
theoretical, but practical (swimming pool analogy)

32.
http://jnaapti.com/
1. Understand that it takes Time
Programming is an art
Enjoy the process
Don't be in a hurry

33.
http://jnaapti.com/
2. Own Your Learning
Don't rely on anyone for
your learning
Learn how to learn – get
to your goal via the
shortest path
Be a lifelong learner –
keep learning, because
“change is constant”

34.

3. Remember the “T” of Knowledge
Pick your forte, outsource/import
the rest
Build your breadth in as many
areas as possible
Build your depth in atleast a few
areas
Don't read from cover-to-cover
Be a Jack of many trades and Master
of a few

35.
http://jnaapti.com/
3.1 – Corollary
Separate your "learning for the heck of it" from
"learning to get things done"
“Learning for the heck of it” is done to expand your T
of Knowledge
Learning to get things done – is need based – begins
with an end in mind
You need both!

36.
http://jnaapti.com/
4. Resist the urge to “Know it All”
You will be bombarded with technologies
There is sometimes an urge to know it all
Be comfortable with uncertainty, it's OK not “Not
Know It All”
Remember that you cannot learn everything – and it's
perfectly alright

37.

5. Distinguish Concept From Technology

38.
http://jnaapti.com/
6. Be Aware of your World
Don't be outdated before you launch
Remain “Technology Nimble” and be “Future
Compatible”
Attend Meetups/Events to expand your breadth
Read a lot
Be aware of what is happening around you

39.
http://jnaapti.com/
7. Don't Reinvent the Wheel
Look for ready-made solutions for parts of the
problem you are trying to solve
Is there some open-source software that does “x”
Is there a service that I can use that does “y”

40.
http://jnaapti.com/
8. Don't Repeat Yourself
There are enough things to learn, don't waste time re-
learning what you already learnt
Have a system to capture your knowledge so that you
can refer to it when need comes
My personal preference: Zim Wiki

41.
http://jnaapti.com/
9. Pick a Mentor
In the initial days you need help
Have somebody you can talk to once in a while
Don't over design or under design – mentors can help
The teacher never gives up, students do

42.
http://jnaapti.com/
10. Jump into the Swimming Pool
Don't learn swimming on a whiteboard
Don't think “What it's like if I jump in”
Don't think “What if...”

43.
