What Is Pair Programming?

It is not hard to guess that pair programming involves making two developers work on one machine. Both developers use one mouse and keyboard. While one developer will write the code, the other will evaluate and help identify the problems in the code.

6 Driver-Navigator Patterns That Make Pair Programming More Productive

Why Pair

On teams, developers want to get more done. Less experienced developers need to learn from the more experienced developers. The organization needs to be structured to avoid needing n squared communication channels.

“Pair programmers: Keep each other on task. Brainstorm refinements to the system. Clarify ideas. Take initiative when their partner is stuck, thus lowering frustration. Hold each other accountable to the team’s practices. Pairing” - Kent Beck

Pairing allows developers to …

  • Produce better solutions
  • Share knowledge and context on the fly
  • Mutual learning and skill development

Definitions

Pair programming is the practice of pairing up to work on development tasks. Most people think of two developers sitting at the same machine, sharing a keyboard. With the increasing popularity of remote work, it is now possible to pair program while thousands of miles apart.

Driver

Fingers on keys; typing code.

Navigator

The developer that indicates what should be typed; decides the direction to go.

Most forms of pairing involve taking turns typing. One person types (the driver) while the other person thinks through what is being done, and what needs to be done next (the navigator). These roles are frequently swapped.

Both members must verbalize their thought processes when pairing to be effective. Successful pair programming relies on successful communication as much as programming skills. The premise of pair programming is that when working on a complex task, “two heads are better than one.”

Patterns

Strong Technique

The Strong Technique is an approach where the driver does nothing that the navigator did not direct.

For the driver to provide an idea, they must handover the system to the partner and then carry out the control from the navigator position. This approach completely engages the observer.

Traditional Technique

Traditionally, pair programming has been popularized through the driver-navigator technique. Ideally both the team members should switch roles at times for better results.

With this style of pair programming, the navigator often loses interest. Possibly because the person in charge of typing is not communicating well, or perhaps the navigator does not want to bother him. Many times the driver puts forth, “just a minute, I’ve got an idea …” and continues working; the navigator is left behind.

Why Pair Programming Is Fantastic

If you work in an engineering field, you must have heard this term tossed around quite a bit. Especially, among programmers. If you are a programmer and have never heard this term before, nothing to worry about. But the sooner you become acquainted with the concept, the better. In this article, I will be answering the question, “what is pair programming?”, the common steps involved, and the roles of the pairs.
Let’s first understand what the term “pair programming” means.
What is Pair Programming?
Simply put, pair programming is an agile technique where two programmers work on a problem at a single workstation.
Workstation requirements:

One computer
Two keyboards
Two mice
One monitor or two mirrored monitors
Writing code is not everything, but understanding the problem is.

The art of problem-solving
As Richard Feynman’s technique points out, thinking out loud and explaining the problem or a solution to someone is the simplest way to tackle a problem. The simpler the explanation, the better the understanding.
Solving tiny problems at a time and, in turn, achieving smaller milestones, is crucial in problem-solving. Therefore, the problem is first broken down into tiny achievable tasks.
In general, the software engineering process encourages programmers to ask as many questions as possible regarding the problem. When, why, how, where, etc. Some things can be assumed — like that limits that need to be set, and ultimately the solution needs to be full-proof that passes most edge cases. The solution should assure easy understandability, extensibility, and long term maintainability. To write tests for success, failures, and important edge cases one should know what those cases are which can be found out by asking good questions.
The most common mistake programmers make is to jump into solutions. The creative process needs time and iterations. Try to avoid this mistake by taking enough time to understand the problem at hand so you don’t end up solving the wrong problem or rather in a wrong manner.
The pair programming technique involves two people working on a single block of code, one driving the process and providing a high-level bird’s eye view of the steps called the Navigator. With the counterpart typing out the code and taking take care of the semantics called the Driver.

Coding 101: Programming Language Building Blocks

This article will introduce the concepts and topics common to all programming languages, that beginners and experts must know!

Do you want to learn a programming language for the first time?

Do you want to improve as a Programmer?

Well, then you’re in the right place to start. Learn any programming language without difficulty by learning the concepts and topics common to all programming languages.

Let me start by answering the following questions:

  • Why learn Programming?
  • What is Programming?
  • How to Learn a Programming Language?

Why learn Programming❔

Programming develops creative thinking

Programmers solve a problem by breaking it down into workable pieces to understand it better. When you start learning to program, you develop the habit of working your way out in a very structured format. You analyze the problem and start thinking logically and this gives rise to more creative solutions you’ve ever given.

Whether you want to uncover the secrets of the universe, or you just want to pursue a career in the 21st century, basic computer programming is an essential skill to learn.

_– _Stephen Hawking

Everybody in this country should learn how to program a computer… because it teaches you how to think.

_- _Steve Jobs

Programming Provides Life-Changing Experiences

Programming always provides you with a new challenge to take risks every time and that teaches you to take risks in your personal life too. The world is filled up with websites, apps, software and when you build these yourself you’ll feel more confident. When a programmer solves a problem that no one has ever solved before it becomes a life-changing experience for them.

What is Programming🤔?

program is a set of instructions to perform a task on a computer.

Programming is the process of designing and building an executable computer program to accomplish a specific task.

Well, according to me programming is like raising a baby. We provide knowledge (data) to help understand a baby what’s happening around. We teach a baby to be disciplined (and much more) by making rules.

Similarly, a computer is like a baby. We set rules and provide data to the computer through executable programs with the help of a Programming Language.

That’s it👍. If you can understand this basic concept of programming, you’re good to go. Pick up a programming language and start learning. Read the following section to get an idea of where to start.

My recommendation is to choose Python Programming Language as a start, because it’s beginner-friendly.

If ENIAC Engineers Could Pair Program, So Can You

By now, I have heard several excuses from developers and managers who had their reasons not to pair program. As far as I’ve seen, the doubts and inhibitions arise from experiences involving bad practices.

Two of the earliest ENIAC engineers, Jean Bartik and Betty Snyder were a pair in the 1940s when they worked on the first ENIAC machines. “I believe that the best programs and designs are done by pairs, because you can criticise each other, and find each other’s errors, and use the best ideas,” Bartik said.

If two of the early programmers in the history of computer science could pair, so can you.

Once you master the skill, pair programming can be rewarding and starts to become more fun. Trust me when I say that pair programming works for everyone. You just have to find the style that works for you and your partner.

So, if you are new to this and find pairing intimidating, start small. Start with a small bug or a task that is simple to achieve. The next step would be to pick a personable developer you know to pair with. When you start out, it helps to pair with nicer, communicative people. Lastly, remember that people aren’t mind readers, so be communicative yourself and think out loud as much as possible.

In this article, I’ve listed some basic requirements to have a successful pair programming session.

6 Lessons from Failed Implementation of Pair Programming

Five years in software development has taught me one thing: the word “Software Development” is nowhere close to explaining the complexity behind the term.

Over the years, different methodologies and techniques carried out to make the process easier. In my last project, we were following the agile methodology for software development. We encountered many production issues after our first release. We thought we had a rock-solid approach to filter out as many defects in earlier stages.

So-called Rock Solid Approach

We had four major environments — Dev, QA, Staging, and Prod. The purpose of these environments is mentioned below:

  1. **Dev **— Used by programmers for development activity. They push their code in this environment for unit testing of their changes before moving it to the QA environment.
  2. **QA **— As the name suggests, this environment is used by the testing team for verifying the changes made by developers. This environment is primarily used for testing dev stories in each sprint and demoing the same to product owners.
  3. **Staging **— Once code is ready to go in the next release, then it needs to be placed in the staging environment. The staging environment is a mirror image of the production environment with all similar configurations. This gives the fair idea to test the code before actually putting up into production.
  4. **Prod **— The production environment is the live environment where the application is hosted for all the clients. If any issue comes into this environment, then it is of high severity.
