Quote from the bottom of the website (easy to miss):
> On my Macbook Pro the folder containing Xcode is larger than 13 GB. And to get the .NET application running at work I had to install over 20 GB of applications and dependencies. So, relativity speaking, JavaScript is still ok.
Personally, I completely agree with that. A single gigabyte of hard drive space on a developer's machine or a modern server is not terribly wasteful.
But also, the point about .NET is complete garbage. The full .NET 3.1 SDK download for Mac OS X is around 100MB. Based on that hyperbolic statement I'd be hesitant to trust anything else on the site.
EDIT: I know he says "the application at work" and it's just an offhand comment, but you shouldn't read too much into it. Unless it means "I had to install Windows 10 on a VM" because it uses classic framework libraries that don't work with Mono or something.
