I’ve got an exciting announcement and a big request (with a big offer) for you all.

First the announcement: The print edition of the Ruby on Rails Tutorial book is out! You can buy it now on Amazon.com.

This is great news for anyone who likes good old-fashioned hard copies of books—and for anyone who’s looking for a nice heavy present to put under the Christmas tree.

Ruby on Rails Tutorial print edition

The Rails Tutorial print edition has actually been out since last month, but I’ve been delaying the announcement because Amazon keeps running out of copies.

This is a good problem to have, of course, but it’s definitely an inconvenience when making announcements. And in fact they’re still running out—as of this writing there are only 5 copies left in stock!

But you can delay an announcement only so long, especially with the holiday season upon us.

There are more copies coming, though, so don’t worry—if you order now, you’ll get your copy ASAP.

Now for the request (with a big offer).

When a new book edition comes out, one unfortunate side-effect is that the number of Amazon reviews gets reset to 0. This means the nearly 200 reviews of the 3rd edition—including over 170 5-star reviews—are all gone!

In order to rebuild this review count, I’m hoping some of you will be able to help out by leaving new reviews for the 4th edition (Rails 5):

  1. Leave a review at the Rails Tutorial website.

  2. Leave the same review at Amazon to help rebuild the review count.

As a special bonus, if you leave your Rails Tutorial website review within the next week you’ll receive a free month in the Learn Enough Society (a $29 value). This membership gets you access to all the enhanced Learn Enough tutorials (including Command Line, Text Editor, Git, and HTML), plus streaming videos for the full Ruby on Rails Tutorial. Current Society members will get a free month added to their membership.

(Note that Step #1 is not necessary to get the free month in the Learn Enough Society, but completing Step #2 by leaving a review at Amazon is greatly appreciated.)

Thanks for all your support, and I hope you enjoy the new Ruby on Rails Tutorial print edition!

The Learn Enough HTML to Be Dangerous screencast videos are out! There are two main ways to get them:

  • Get the screencast+ebook bundle.
  • Join the Learn Enough Society. All Society memberships include streaming videos for all the Learn Enough tutorials (Command Line, Text Editor, Git, HTML, Action Cable) as well as the full Ruby on Rails Tutorial, for a total of over 25 hours of video.

At just over 2 hours, the Learn Enough HTML to Be Dangerous screencasts are the perfect length for getting started with HTML without having to slog through 10 hours of video just to learn the basics.

As always, the full written tutorial is available for free online.

Although there are lots of HTML tutorials out there, Learn Enough HTML to Be Dangerous puts things together in a way you probably haven’t seen before:

  • You deploy a live website in the first section.
  • You learn HTML tags in context, using real-world examples.
  • You take the first steps toward Cascading Style Sheets using inline styles.
  • You build a reference table of HTML tags, using the HTML table tag. It’s totally meta.

Learn Enough HTML to Be Dangerous also has 200% more kittens than the average HTML tutorial.

An adorable kitten

HTML is the fundamental language of the Web, and all developers, designers, and even managers should know the basics.

If tech is the new literacy, HTML is the alphabet.

You don’t have to know everything about HTML, of course—just enough to be dangerous.

I’ve just released the screencast for Learn Enough Action Cable to Be Dangerous, which teaches you how to make real-time web applications using Rails and the WebSocket Protocol.

This is cutting-edge web development, the kind of thing that gives you a leg up on the competition when landing a contract or getting a job.

The Action Cable sample app is a real-time chat application, and for this kind of app the screencast format really shines. It’s hard to completely capture the dynamic nature of Action Cable in a written tutorial, but with a screencast you can really see the app come to life.

Topics include:

  • Upgrading a Rails app to Action Cable
  • Message broadcasts using WebSockets
  • Polishing the User Interface with CoffeeScript
  • Advanced enhancements like Markdown support and @-mention notifications

Anyone interested in building real-time apps will benefit from both the ebook and video versions of Learn Enough Action Cable to Be Dangerous.

There are two main ways to get it:

  1. Buy the downloadable ebooks & videos: Get EPUB/MOBI/PDF ebooks & over 2 hours of MP4 videos.
  2. Join the Learn Enough Society: Get access to a special enhanced online version (with community answers to exercises) and free streaming versions of all 2+ hours of the Action Cable screencasts.

Either way, I hope you enjoy learning enough Action Cable to be dangerous!

I’m Michael Hartl—author, educator, and entrepreneur. I’m probably best known as the creator of the Ruby on Rails Tutorial, a book and screencast series that together constitute one of the leading introductions to web development. Once called his “favorite book” by Wikipedia founder Jimmy Wales, the Ruby on Rails Tutorial currently has over 150 5-star reviews at Amazon. I’m also (in)famous for creating Tau Day and The Tau Manifesto, which have inspired an international movement dedicated to the proposition that “pi is wrong.” (For example, as a result of The Tau Manifesto, MIT releases their admissions decisions each year at “Tau Time” (6:28 p.m.), and typing tau/2 at Google yields 3.14159…) Finally, I’m a founder of Softcover, a publishing system and sales platform for technical authors, which among other things powers both The Tau Manifesto and the Ruby on Rails Tutorial.

I’m a graduate of Harvard College and have a Ph.D. in Physics from Caltech, where I studied black hole dynamics and was an award-winning instructor in theoretical and computational physics. I’m also an alumnus of Y Combinator, the entrepreneur program that has produced companies such as Dropbox and Airbnb. (Alas, my own Y Combinator startup was neither Dropbox nor Airbnb.)
