Aw man, Hacker News is going to fail soon because hackernews.com is taken by someone else. (At least this means I'll spend my time writing useful software instead of making snarky comments on the internet.)

On a more serious note, if I'm reading the article right, `ipython` is still the IPython CLI interface, it's just that less-related commands like `ipython notebook` are now `jupyter notebook`, right?
