"GIF" or "JIF"?

Steve Wilhite created the Graphics Interchange Format for Compuserve in 1987. He received a Webby Award for it and delivered this five-word acceptance speech "It's pronounced JIF, not GIF."
 

Dev Speak =                                     

How NOT to talk to a developer

"Hi, you look like you're concentrating on something really hard, you should stop what you're doing and hear my 'Million Dollar Idea', but first I'll need you to sign this paper stating that you won't also have ideas.  Then I can tell you about my lack of business experience which will have 1billion features and be worth so much money, you won't be upset that I'm offering 2% of my company in exchange for 5 years of FREE work, just trust me.
... can you have it done this weekend?  I want to show a friend of mine so he can change the whole thing"

Ideas are important 

and fun

Building ideas and making them financially viable is hard.

Lots of places and things

to communicate

?

OPEN SOURCE

Github

NOT Github

simple.

distributed.

friendly.

WHy?

Need
Jobs
$$$$$$$$$$$$

Developers Communicate

Can Their software Communicate?

That's API

API

Most mean Web API now.
SOAP and REST API services are usually specification of remote calls that are exposed.
API

API

WHY API?
Pay:
  • Provide a technological service (SAS)
Free:
  • 60% of all Ebay purchases are done via API
  • Outgrow competitors like Google Maps did
  • Yummy user data to sell (Facebook > 140 Bil)

Let's talk Tech

Web API is HTTP secured over SSL/TLS
Usually returns XML or JSON
Is it a Web Service?
Leaving SOAP and SOA and moving towards REST and ROA

What is REST?

Representational state transfer (REST)
Resource: zoo.com/animals
get - Lists URIs of animals
Resource: zoo.com/animals/bill_the_tiger
get - Retrieves a representation of the addressed member of the collection.
GET - PUT - POST - DELETE

REST vs SOAP

REST is an architectural style, while SOAP is a protocol.  
Therefore there is no "official" standard for RESTFul web APIs.
REST uses standards like HTTP, URI, XML, JSON as Hypermedia

Caveats

You had better use HTTPS!
AND
You're creating an external dependency
AND
API's aren't always a great combination

COMBINE ALL THE THINGS

HOW?

Public Key Cryptography
Like BitcoinYAY BUZZWORDS

Public Key Encryption

It's an easy concept
just hard math (you never have to do)

SYMMETRIC VS ASYMMETRIC

Symmetric: Key to lock, also unlocks
  • Like House Keys
Asymmetric: 
  • Like a relationship
  • jj kinda

Asymmetric

One key can Encrypt - Usually Public Key
One key can Decrypt - Usually Decrypt Key
Benefits?
Secrecy
Accountability
Integrity

HOW?

don't get to mathy on me!
What is the square root of 4?

X² = 4

x = ± 2

X could be any of 2 answers!?
LET'S EXPLOIT THE HELL OUT OF THIS

Say Hello To Modulus

Modulus is the remainder after division.
256 ÷ x -> has a remainder of ZERO
What is X?
1? 2? 4? 8?
16? 32? 64?
128? 256?

Magic of Primes

Why large primes?
The remainder can only be as big as the divisor.
ALSO:  Modulus with a prime and it's primitive root, allow an even an distribution along that prime.

3^x MOD 17 = ?

3^1 MOD 17 = 3
3^2 MOD 17 = 9
3^3 MOD 17 = 10
3^4 MOD 17 = 13
3^5 MOD 17 = 5
3^6 MOD 17 = 15
3^7 MOD 17 = 11
3^8 MOD 17 = 16
3^9 MOD 17 = 14
3^10 MOD 17 = 8
Look at that distribution!
Easy to calculate, hard to reverse!

Now What?

Raise 3 to secret power & mod 17; make the result public. Taking anyone else's public result and raising it to your secret power will equal the same for the person does the same for you.

*POP*
 

TOO MUCH?

Just remember:

Developers: Meet up weekly and are friendly if approached right.
Open Source: Is awesome, and can help you solve complex problems for free.
API:  Allows software to talk to one another, and gives you functionality in return for your $ or data.
Public Key Crypto: Needs large primes, is hard to undo, has 2 parts (public/private), WORKS!

THE END
