This document provides an overview of programming terminology, languages, and factors to consider when hiring a developer. It defines terms like platform, framework, middleware, and full stack. It introduces popular languages like Java, C, C++, C#, PHP, Python, Ruby, JavaScript, and SQL. It also discusses unusual languages like Whitespace, LOLCODE, and Brainfuck. Finally, it lists qualities to look for in a developer like knowledge, efficiency, and communication skills, and provides common project FAQs.
![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.
}
}

![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;

![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.

Entrepreneur’s guide to programming
- 2. Rundown Terminology - Nerd talk Programming Languages Why do we have so many languages Code Examples Bizarre coding languages What to look for in a developer F.A.Q
- 3. Nerd Talk Platform Framework Middleware Full Stack Compiled vs Interpreted
- 4. Platform
- 5. 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.
- 6. Framework
- 7. 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 NodeJS Express Meteor PHP Zend Laravel Phalcon Ruby Ruby on Rails Sinatra
- 8. Middleware
- 9. 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.
- 10. Full Stack
- 11. Full Stack One 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.
- 12. 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.
- 15. 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
- 16. 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, worldn"); } C# Java Javascript Python
- 17. 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"; }
- 18. 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!"); } }
- 19. 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; }
- 20. 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!'; ?>
- 21. 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"
- 22. 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"
- 23. 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");
- 24. 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;
- 25. 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.
- 26. 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. HAI CAN HAS STDIO? VISIBLE "HAI WORLD!" KTHXBYE
- 27. 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. ++++++++++[>+++++++>++++++++++>+++>+<<<<-] >++.>+.+++++++..+++.>++.<<+++++++++++++++. >.+++.------.--------.>+.>.
- 28. 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.
- 29. 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?
