RubyTapas Episode 1: Binary Literals

It’s been well over a year since I announced this project, but today I’m proud to finally be launching RubyTapas, my subscription screencast service!

RubyTapas is all about small plates of gourmet code: brief, focused screencasts on Ruby techniques, idioms, and standard libraries, as well as practical applications of OO design principles in Ruby.

New RubyTapas episodes will go out three days a week. I’ll be publishing the Monday episodes for free on this site, but you’ll need to subscribe to get the Wednesday and Friday episodes. In addition to receiving all three episodes a week, subscribing will get you:

  • Full transcripts of each episode.
  • Full source code for each episode.
  • Access to the complete archive of previous episodes.
  • Email notification as soon as a new episode is ready.

Now without further ado, here’s the inaugural episode, which covers Ruby’s handy syntax for binary literals!

(Too low-res? Click the full-screen button and wait a few moments, the resolution will increase automatically.)

Like what you see? This is just a taste of RubyTapas! Sign up today to get two videos a week, along with full source code and transcripts. Or click here to learn more.

    Hi Avdi,

    I find 2 min. a little bit too short. Will the pro/paid videos be longer?
    About 4 or 5 min. would be great :-)
    One other thing, you did in the video was not clear to me: I see, you are using Ruby mode in Emacs, but I didn’t know, you could execute all statements and print the output in the comment nearby. How do you do that? Is this a part of Ruby mode or a custom Ruby extension?

      While I’ll definitely evolving with time and feedback, the plan right now is to keep all of the videos between 1 and 5 minutes. I want them to be exactly long enough to deliver one new idea, and no longer. If I think a topic warrants 4-5 minutes then I’ll use that much time; if not, it’ll be shorter.

      I’ll definitely be covering how I do the in-buffer evaluation in a future blog post.

        When you do that episode can you do it in vim? trololol

      Given 3 screencasts p/w I actually quite like the 1-5 min format… I have a big backlog of rails casts I’m trying to catch up on because they go for close to 20 mins each

    Oh this is super awesome Avdi. Subscribed.

    Another tip: When writing binary literals for permissions, take you can write them with underscores like this: `0b111_101_101`
