I'll indications point to this GitHub user [1], Alexis Sellier [2], as the engineer behind this. Good luck with such an ambitious goal. I'd love to see it.

For someone who is singing the praises of linux, his website (it does look like his personal website) is pretty awesome. Specially http://cloudhead.io/

To become a vim power user, you will really need to understand how and why vim works the way it does and how you should think about editing while using vim. Once you have gone through some of the great tutorials on basic vim usage take a look at these:

Good explanation of how vim commands are actually formulated (Stack Overflow answer): http://stackoverflow.com/questions/1218390/what-is-your-most-productiv…

I'd just like to mention popol here [1]:
Popol is designed as a minimal ergonomic wrapper
around poll, built for use cases such as peer-to-peer
networking, where you typically have no more than a
few hundred concurrent connections. It’s meant to be
familiar enough for those with experience using mio,
but a little easier to use, and a lot smaller.

I don't have any reference material/tutorials, but my major breakthrough with Vim was when I understood that normal mode is the norm. Anytime you're not entering text, be in normal mode. Remap jk or jj to escape. Get in the habit of typing it whenever you're done adding text. Use hjkl for movement instead of the arrow keys. Learn the f,t, and o commands.

What's the deal? That's not the original URL. This is:
http://cloudhead.io/2011/04/18/why-osx-doesnt-cut-it/
Did that site get the author's permission to post it elsewhere?

I've been using something very similar for my blog for the past month or so, it's called Toto. Flat file, git, Ruby, Markdown, Disqus, etc. Check it out: http://cloudhead.io/toto
and a good post on how to get up and running http://fadeyev.net/2010/05/10/getting-started-with-toto/ . It was really fast and simple to go from 0 to blogging. The default template is nice too (jlank.com)

Thanks for your comment. I have to say I am a bit hurt by Wordpress UX and (no flamewar intended) its PHPness.
I think I am going for Posterous. If I could host my own blog there are three interesting options I would ponder:
toto - http://cloudhead.io/toto
jekyll - http://jekyllrb.com
timeless - http://timeless.judofyr.net/timeless

Does OS X even let you turn off an external monitor yet? (Via a control panel setting or other software driven interface?) In Linux and Windows I can use the OS to turn it off. The Mac forces me to unplug the monitor or power it off manually.
Didn't OS X users just get the ability to resize windows by any edge or corner? They only had to wait 10 years for that wonderful feature.
How about being able to properly replace the Dock? You can't, because Apple does not allow non-Apple programs to affect NSScreen visibleFrame.
Maybe you can tell us how much Finder can be controlled versus the file browsers in Windows or say Gnome/KDE? Wait, nope - turns out it's sorely lacking in extendability hooks.
Furthermore - OS X has shitty package management and limits what you can do with your terminal as well because you cannot replace certain packages without breaking your entire system - http://cloudhead.io/2011/04/18/why-osx-doesnt-cut-it/
So, no...OS X is not as maleable as other operating systems.
