Excellent question. The main reason is that GitHub is great for free public repos, which I generally like having as the default, and using GitHub also enables a Secret Bonus™ at the end of the Git tutorial. When it comes to web apps, though

I don't know Elixir yet, but I'm collaborating with someone who does. I think the plan is he teaches me, then I teach you. :-) I've heard great things about Elixir, and its design is heavily influenced by Ruby, so I think it

Great, thanks! And linking directly to the commit—now that's thinking Git. :-)

Oh, for sure. I use it all the time. There's no doubt `git push -f` is useful. Even less doubt that it's dangerous . ;-)

The `git push --force` command didn't quite make the cut, but if you can think of a place where it fits into the current tutorial I'm certainly open to adding it. Maybe it fits in as an exercise somewhere? UPDATE: yebyen has sugge

Thanks! Developing the theme of technical sophistication has been one of the most surprising and gratifying side-effects of making tutorials designed for complete beginners. I'm hoping to continue the theme in each subsequent Learn E

Oh, that's definitely planned. :-) Even better, my Learn Enough to Be Dangerous cofounders and I are working on a subscription service that will integrate text and videos for the command line, text editor, and Git tutorials, with many

Argh, typos. For the record, here's what I meant to write: I've used the phrase cargo cult startup to describe this phenomenon (after Feynman's phrase "cargo cult science"): going through the motions in the hopes
