Choosing Your First Programming Language

Which is easiest, the most professionally useful, the most newbie-friendly?

By

Many new programmers struggle when it comes to selecting their first language to learn.  Which is easiest, the most professionally useful, the most newbie-friendly?  Lets find out by showing you a range of options, their strengths and weaknesses, and some information about the most common programming languages in demand today.  At the end, we’ll make some recommendations and you’ll understand a bit more about why they were chosen.

The Task At Hand
Every job requires the right kind of tool, and each programming language can be thought of as a separate tool.  Just like some tools are good for hammering nails, driving screws, and leveling screws, some programming languages are innately more suitable than others for tasks like designing a website, interpreting text, or reacting to user input.

Lets go through a few common use cases:

Language

Typical Usage

Java

Thick-client applications, large web apps, web applets, cross-platform

C# / .Net

Windows applications, iPhone apps

PHP

Web Application back-ends

Javascript

User interaction through web browser

Python

Science apps, computer admin tools, automating repetitive tasks quickly, can run on Linux and Windows (like java)

Ruby

Robust & Large web applications

Perl

Working with lots of text

Bash

Automating Linux Activities (like starting/stopping processes)

C/C++

Medium to Large projects, Embedded development, applications where speed is a factor

All of these languages can perform the same (or nearly the same) tasks as all the others, but the amount of effort can vary widely from language to language.  You’ll see that in some of the examples in the next section…

Detail-Oriented
All programming languages rely on structure to perform their tasks.  This structure is known as Syntax.  The syntax for English and Japanese are night and day, but the syntax for French and Spanish are very similar (if you remember your language classes from high school!).  The same applies to computer languages.  Lets look at some examples:

Java

C#

public class HelloWorld {
public static void main(String[] args) {
System.out.println(“Hello, World”);
}
}

public class Hello1
{
public static void Main()
{
System.Console.WriteLine(“Hello, World!”);
}
}

vs

Perl

Python

#!/usr/bin/perl
print “Hello World.\n”;

#!/usr/bin/python

print “Hello World\n”

 

You can see that Perl and Python are nearly as identical to each other as Java and C# are!

programmingThis makes sense because many languages are modeled after one another.  By choosing a language that is syntactically similar to many other languages, you can practically learn multiple languages at once!

Hey, by the way, if you looked closely at those examples, you’ll notice some are simple, others are complex, and some require semicolons at the ends of lines while others don’t.  If you’re just getting started in programming, sometimes it’s best to choose languages without many syntactical (or logical) rules because it allows the language to “Get out of its own way”.  If you’ve tried one language and really struggled with it, try a simpler one!

Setup:

If you’ve seen your use case mentioned in the table above, or have decided on a language already, you’ll need a way to run it.  Generally, scripting languages require something called an Interpreter whereas C and C++ require compilers.  Almost all of the languages mentioned in this article (with the exception of C#) are easiest to set up with any flavor of Linux — it really doesn’t matter which kind.  C# is a special case because you need Visual Studio and Windows to use that.

PHP really requires a lot of work to set up in tandem with Apache/IIS, so we’ll save it for your own Googling or another article.  The languages and links below are the easiest to set up.

Language

Windows

Ubuntu Linux Console Command

Ruby

http://rubyinstaller.org/

apt-get install ruby

Python 2.7

http://www.activestate.com/activepython/downloads

apt-get install python

C#/.Net

http://www.microsoft.com/visualstudio/eng/downloads#d-2012-express

N/A

Java

http://www.oracle.com/technetwork/java/javase/downloads/index.html

http://www.eclipse.org/downloads/

apt-get install openjdk

C++

http://www.microsoft.com/visualstudio/eng/downloads#d-2012-express

apt-get install build-essential gcc

 

You can see that things on Linux can be quite easy to set up, but of course requires some amount of familiarity with the operating system.  If you’re not scared to jump into Linux feet-first and take some time to Google your issues, I highly recommend that you use Linux.  Either way, you’ll be using the command line in order to debug your programs anyways.

So All This Information Is Nice But…
You need to make a decision, right.  Well, lets make a couple more charts and then get you started:

1. I’m a Windows User and I want to Get Into Programming
If you’re making something simple and want some experience that will translate into real-world usefulness, start with C#/.Net — setup is easy, the Visual Studio really helps you out, and there are plenty of resources to help you, including technet and MSDN directly from Microsoft!

Those languages aren’t as easy as Python, but Python isn’t going to help you out as much if you’re looking to make a simple graphical application.  That being said, if you just need a command-line utility, take a close look at Python.

2. I’m familiar with Linux and I want to make/automate something
Python.  Simple, fast, incredibly powerful, easy to use and experience with it translates fairly well into other languages.  Absolutely a must for beginners willing to get their feet wet with Linux.

3. I want to build a website
JavaScript and PHP — These languages require the most amount of know-how to set up (you have to install a webserver and make sure it’s configured to run PHP) but aren’t too complicated once you get that ball rolling.  PHP isn’t going to get you as much experience working with modern programming languages unless you use it in an Object-Oriented style though.

JavaScript is very useful to know and is easy to learn.  You’ll get a lot of use out of it, even without PHP.  In fact, you can make and run Javascript programs without any setup, right in your browser.

Just give me a Language!
Python.  It’s easy, already used by thousands, very extendable, doesn’t require as much attention to detail, and allows beginners to learn logic basics before going into object-oriented programming.

Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?
At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices. Sessions focused not just on the cultural shift needed to grow at scale with a DevOps approach, but also made sure to include the network ”plumbing” needed to ensure success as applications decompose into the microservice architectures enabling rapid growth and support for the Internet of (Every)Things.
How do you securely enable access to your applications in AWS without exposing any attack surfaces? The answer is usually very complicated because application environments morph over time in response to growing requirements from your employee base, your partners and your customers. In his session at @DevOpsSummit, Haseeb Budhani, CEO and Co-founder of Soha, shared five common approaches that DevOps teams follow to secure access to applications deployed in AWS, Azure, etc., and the friction an...
Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
JavaScript is primarily a client-based dynamic scripting language most commonly used within web browsers as client-side scripts to interact with the user, browser, and communicate asynchronously to servers. If you have been part of any web-based development, odds are you have worked with JavaScript in one form or another. In this article, I'll focus on the aspects of JavaScript that are relevant within the Node.js environment.

Containers are changing the security landscape for software development and deployment. As with any security solutions, security approaches that work for developers, operations personnel and security professionals is a requirement. In his session at DevOps Summit, Kevin Gilpin, CTO and Co-Founder of Conjur, will discuss various security considerations for container-based infrastructure and related DevOps workflows.
Microservices are hot. And for good reason. To compete in today’s fast-moving application economy, it makes sense to break large, monolithic applications down into discrete functional units. Such an approach makes it easier to update and add functionalities (text-messaging a customer, calculating sales tax for a specific geography, etc.) and get those updates / adds into production fast. In fact, some would argue that microservices are a prerequisite for true continuous delivery. But is it too...

Puppet Labs has published their annual State of DevOps report and it is loaded with interesting information as always. Last year’s report brought home the point that DevOps was becoming widely accepted in the enterprise. This year’s report further validates that point and provides us with some interesting insights from surveying a wide variety of companies in different phases of their DevOps journey.
What we really mean to ask is whether microservices architecture is SOA done right. But then, of course, we’d have to figure out what microservices architecture was. And if you think defining SOA is difficult, pinning down microservices architecture is unquestionably frying pan into fire time. Given my years at ZapThink, fighting to help architects understand what Service-Oriented Architecture really was and how to get it right, it’s no surprise that many people ask me this question.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...
"ProfitBricks was founded in 2010 and we are the painless cloud - and we are also the Infrastructure as a Service 2.0 company," noted Achim Weiss, Chief Executive Officer and Co-Founder of ProfitBricks, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.
The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
