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 pleased to announce that Learn Enough Text Editor to Be Dangerous is now available at Amazon.com, where it joins Learn Enough Command Line to Be Dangerous as part of the Learn Enough Developer Fundamentals series.

Learn Enough Text Editor to Be Dangerous is designed to help you learn to use what is arguably the most important item in the aspiring computer magician’s bag of tricks: a text editor.

Unlike other text editor tutorials, which are typically tied to a specific editor, Learn Enough Text Editor to Be Dangerous is designed to introduce the entire category of application. This includes Minimum Viable Vim, covering the ubiquitous Vim editor, and a thorough introduction to Atom, a powerful and easy-to-use editor from GitHub.

The price of Learn Enough Text Editor to Be Dangerous at Amazon will eventually be $9.99, but I'm offering a 30% launch discount for the first week, so it's only $6.99 if you buy now. In addition to the native Kindle format, each purchase includes a claim link for free copies of the PDF & EPUB formats as well.

If you previously read the free online version, it would also be much-appreciated if you could leave a review at Amazon.

As just noted above, Learn Enough Text Editor to Be Dangerous is available for free online, and for direct purchase as well, but having the ebook up at Amazon means even more people can find the Learn Enough tutorials and start learning technical sophistication.

P.S. Get 30% off Learn Enough Text Editor to Be Dangerous at Amazon.com through Wednesday 10/12.

P.P.S. If you could leave a review that would also be much-appreciated!

After launching a more advanced Action Cable tutorial a couple of weeks ago, Learn Enough is getting back to basics with one of the most important technologies on the Web: HTML.

Learn Enough HTML to Be Dangerous by Michael Hartl & Lee Donahoe covers the basics of HyperText Markup Language, the language of the World Wide Web. As of today, the full tutorial is online for free, and available for purchase in EPUB/MOBI/PDF formats.

At around 130 pages, it’s the perfect length for getting started with HTML without having to slog through 500 pages just to learn the basics.

Although there are lots of HTML tutorials out there, Learn Enough HTML to Be Dangerous puts things together in a way you 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

This new title is the first in a new trilogy of Web Basics, which is both the perfect sequel to the Developer Fundamentals trilogy and a great supplement to the Ruby on Rails Tutorial.

HTML is the fundamental language of the Web, and every developer, designer, and even manager 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’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.)
