Why I Recommend Against Hackety Hack

Disclosure: I sell a couple books that teach programming to kids (and are free to download). I don’t personally view them as being in competition with Hackety Hack, but someone else might.

Hackety Hack was a project originally started by _why the lucky stiff to teach kids programming in Ruby. It often comes up in “I want to teach my kid programming” forum threads. So I downloaded Hackety Hack and decided to give it a try.

I found Hackety Hack to be frustrating and was very unimpressed with it, and do not recommend it as a way to teach programming to a beginner.

It’s kind of crap.

Its main flaws are:

  • It has little actual content. It is very short and covers programming neither widely nor deeply.
  • The presentation style is sort of a “wall of text” format, where programming concepts almost never have more than one example.
  • There are NO error messages or feedback at all if you make a typo in your code. (Pressing Ctrl-/ does not bring up an error console in the Windows version like the instructions say it does.)
  • And at least for the Windows version, it crashes a lot. A LOT. I had to restart it at least a half dozen times before making it through all the way. It even crashed twice while I was writing this blog post. (Apparently this is also a problem with the OS X version as well.)
  • The editor doesn’t have basic features: you can highlight text, but there’s no point because you can’t copy or paste. There is no Select All. There is no Undo. Pressing Ctrl-C, Ctrl-V, Ctrl-Z, or Ctrl-A just inserts a weird Unicode error character into the text. (There’s nothing like highlighting a bunch of code, pressing Ctrl-C to overwrite it all with a Unicode character, and then pressing Ctrl-Z to just get another Unicode character, realizing that all your code is permanently gone.)

There’s a few other minor gripes I have with it: The upload feature doesn’t work at all (even though you’ll get a “Uploaded!” confirmation). On the “Your Preferences” page, the link to set up an account just takes you to the http://hackety.com/ home page, instead of specifically to the http://hackety.com/users/sign_up page (though there isn’t much at all to the online content anyway). It doesn’t remember the accounts that get signed in, making switching between multiple accounts (like in a classroom setting) a pain. After uploading, the menu doesn’t give you the URL where I can find your uploaded program online. (But again, the upload functionality doesn’t work.)

In the file editor, if you don’t save your program before running it, clicking Run simply does nothing (there’s no, “You need to save first.” message). Your program won’t run until you remember to first click Save.

Hackety Hack seems like it hasn’t had a lot of time spent polishing it or paying attention to the details. (For example, there’s a couple grammar and spelling mistakes in the text.) And again, there really isn’t all that much to Hackety Hack. It is short. Very short. There are only four lessons:
