F.A.Q

Nerd Talk

Platform

Framework

Middleware

Full Stack

Compiled vs Interpreted

Platform

Platform

Provides a base to deploy and run apps

Hardware Architecture & some software on top of which other apps operate

Multitasking, Memory management, access to disk & file system, networking, security, etc..

Platform as a service (PaaS) – Heroku The provider(Heroku) provides the networks, servers, storage, and

other services that are required to host the consumer's application.

Framework

Framework

Helps design, develop & bind together different components of

your app

Collection of support programs, a scripting language, code libraries. Each library provides specific functionality

Functions provided by framework are exposed through API’s

Highly flexible and reusable

NodeJSExpressMeteor

PHPZend

LaravelPhalcon

RubyRuby on Rails

Sinatra

Middleware

Middleware

Allows apps to communicate with each other, regardless of platform or vendor

Support your apps from the outside, not tied/bundled with your code.

“Software Glue” which helps software developers perform communication and input/output, so they can focus on the specific purpose of their application.

Full Stack

Full StackOne with familiarity in each layer, if not

mastery in many and a genuine interest in all software technology.

Good developers who are familiar with the entire stack know how to make life easier for those around them.

1. Server, Network, and Hosting

2. Data Modeling

3. Business Logic

4. API Layer / Action Layer / MVC

5. User Interface

6. User Experience

7. Understanding what the customer and

business need.

Compile vs Interpreted

Compile – Turning high level source code into low level machine code, code specific to a processor or operating system. Usually faster.

Interpreted – Another program reads and then executes the original source code. More portable and easier to create.

Compile vs Interpreted

Programming Languages

Java

It is intended to let application developers "write once, run anywhere" (WORA).

class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello World!"); // Display the string. }}

Enterprise software

Web based content

Games

Mobile apps

Android Operating System

C Language

General purpose programming language.

Building Block for:

Mostly used for implementing operating systems and embedded apps.

#include <stdio.h> int main(void){ printf("hello, world\n");}

C#

Java

Javascript

Python

C++

A general purpose programming language that is free-form and compiled.

Mostly used in systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games

# include <iostream> int main(){ std::cout << "Hello, world!\n";}

C#

C♯ is intended to be a simple, modern, general-purpose, object-oriented programming language.

Developed by Microsoft

using System; class Program{ static void Main() { Console.WriteLine("Hello, world!"); }}

Objective-C

A general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.

It is the main programming language used by Apple for the OS X and iOS operating systems.

#include <stdio.h>#include <objpak.h>int main(int argc,char **argv){ id set = [Set new]; argv++;while (--argc) [set add:[String str:*argv++]]; [set do:{ :each | printf("hello, %s!\n",[each str]); }]; return 0;}

PHP

PHP started life as a series of perl scripts for homepages, hence its original name, "Personal Home Pages". It has now grown to be a fully fledged language, with its own advantages and quirks.

Originally designed to create dynamic web pages, PHP now focuses mainly on server-side scripting.

<?php // Hello World in PHP echo 'Hello World!';?>

Python

Emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C.

Python is used as a scripting language for web applications, video games, artificial intelligence tasks, operating systems.

print "hello world"

Ruby

"I wanted a scripting language that was more powerful than Perl, and more object-oriented than Python. That's why I decided to design my own language.“

Used to develop web applications, to web servers themselves, to intelligent graphing libraries, to picture recognition engines, to threaded database servers, to low-level system utilities

puts "Hello, world"

Javascript

Dynamic computer programming language. It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed.

Also used in server-side programming, game development and the creation of desktop and mobile applications.

document.writeln("Hello, World");

SQL

Not a programming language, but a query language designed for managing data held in a relational database management system

SELECT 'Hello World!' FROM dual WHERE id = 1;

Bizarre languages - Whitespace

Whitespace Most modern programming languages do not consider white space

characters (spaces, tabs and newlines) syntax, ignoring them, as if they weren't there. We consider this to be a gross injustice to these perfectly friendly members of the character set. Should they be ignored, just because they are invisible? Whitespace is a language that seeks to redress the balance. Any non whitespace characters are ignored; only spaces, tabs and newlines are considered syntax.

Bizarre languages - LOLCODE

LOLCODE The language is based off of the LOLCats phenomenon, and uses

LOLCats syntax to make programs run. Or something like that.

HAICAN HAS STDIO?VISIBLE "HAI WORLD!"KTHXBYE

Bizarre languages - Brainfuck

Brainfuck is the most famous esoteric programming language, and has inspired the creation of a host of other languages. Noted for its extreme minimalism, it is designed to challenge and amuse programmers, and is not suitable for practical use.

What to look for in a developer

Knowledge/Comfort - Expertise with a language. Efficiency

Experience

Extendibility – Code can easily be picked up by another developer Code commenting

Version control

Communication – Ability to explain what is happening Customer Service

Accessibility

Attitude

Network – Ability to work with others and get help when needed.

Independent – Make smart, consistent decisions regarding the app.

Marketing – Creative ability to increase engagement.

Price – It’s a business.

Project F.A.Q

What do I need to get started?

Will everyone see my website the same way?

I built a website, how come I don’t have any traffic?

Who owns the website once design work is complete?

How long does it take to develop a website?
