“Every time I start a project, I swear to keep my code spotless and to write tests… but it never works out, and I end up with shit-tastic software”

You’re afraid to make changes to your Ruby app. You don’t have enough tests, and the codebase is tangled by poor design choices. You’ll spend half the day just tracking down a simple mistake. You’ve been cowboy-coding your way to frustration… and now it’s time for a change.

What if your code had good test coverage, and a clean design?

You could add new features with ease. You’d find and fix problems quickly. You could apply a professional development process… and deliver professional results, every time.

You can achieve a clean, well-tested codebase, and it’s not magic.

The three critical skills for producing professional code

What distinguishes professional code from amateur code? Professional code works, and is neatly organized. Amateur code breaks, and is poorly organized. So how do you turn amateur code into professional code?

First, you need to understand and apply object-oriented design. You need to create clearly-defined interfaces, encapsulate behavior, and use polymorphism where appropriate. Of course, that would be easy if you knew all the design elements upfront – but in the real world, you need to evolve your design over time…

By refactoring, you do exactly that. You take an existing design, and make improvements to it, without changing the externally visible behavior. But changing code is risky business, unless…

You write tests. You build a safety net of tests that you can run any time you make a change, automatically alerting you to any breaking changes.

There you have it: object-oriented design, refactoring, and testing. That’s all you really need to know. But how do you learn those skills?

The Professional Ruby Manual shows you how:

You’ll start off with object-oriented design. You’ll learn:

With a solid grasp of object-oriented design, you’ll move on to refactoring. You’ll learn:

Now that you know what makes for clean design, and can safely improve your design, you’ll accelerate your design and development process with tests. You’ll learn:

With the skills you learn in the Professional Ruby Manual, you’ll create clean, well-tested, professional code. You never have to waste another day working with sloppy, untested code. Buy the Professional Ruby Manual, and you’ll be enjoying clean, professional code in no time.

The RubySteps Best Guarantee EVER

I’m confident you’ll love the Professional Ruby Manual. But if for some reason you don’t, just email me within 30 days of your purchase and let me know. I will refund your money no questions asked… and then write a brand-new article on the topic of your choice. How’s that for a guarantee?


Is The Professional Ruby Manual right for me?

If you’ve read this far… then probably! But let me help you out a bit more…

The Professional Ruby Manual covers intermediate-to-advanced topics that are important for professional Ruby developers to understand and apply.

If you’re just getting started learning Ruby, check out The Odin Project’s free Ruby course first, and then come back here. Oh yeah, and be sure to check out my awesome free stuff too :)

What happens when I buy?

You will receive an email from SendOwl with a link to download The Professional Ruby Manual pdf. If you’ve chosen either the video or coaching package, you’ll also receive a text file with links to the videos.

Do you guarantee your work?

Of course :)

When does the video group Q&A session happen? Will it be recorded?

The video group Q&A session date and time is yet to be announced. I’ll give you plenty of advance notice so you can plan it in your schedule, and ask your questions ahead of time. I will also record it, just in case you can’t make the scheduled time.

How does the coaching package work?

To set up the coaching session, just send me an email and we’ll figure out a date and time that works for you. We can do a video session over Skype or Google hangouts, or an interactive screen-sharing session using Screenflow.

Because the coaching session is interactive, I cannot offer a refund once we’ve started it. The coaching session is valued at $199. I’ll remind you of this before we start the session.

Of course if we get disconnected or have technical trouble, we’ll work something out! I’m never going to just leave you hanging :)

What is the RubySteps community?

The RubySteps community is a private Slack channel where RubySteppers hang out, ask questions, and share what they’re learning. One of the best bits of advice I ever received was, “Find the smart, friendly people, and hang out with them.”

That’s what you get when you join the RubySteps community: a bunch of smart, friendly people to hang out with.

Who the heck are you, anyway?

Well my name’s Pat, and I’m a regular guy that loves programming Ruby. I’ve been doing it professionally for over ten years (I stopped counting a few years ago), and have been teaching people Ruby pretty much as long as I’ve been programming it. I love to cook, and play with my dogs.

What if I need help, or have more questions?

Just send me an email – I read and respond to every email I get.
