SpaceX has been very forthcoming with their telemetry data and analysis, so hopefully we'll hear what happened soon.
I've been using Gentoo for many years, and temporarily switched to Funtoo on my personal laptop. I've since graduated and don't spent nearly as much time on my laptop as I used to, which these days mainly runs MythTV.
I don't think I'd continue with Gentoo - it takes too much time to sort through updates, figure out which packages need to be masked, etc. I'd rather go to Arch next, although I was considering Debian unstable.
Recently, my video card stopped being supported by the newest nvidia graphics, and the newer versions of Xorg weren't compatible. My masked list is growing as more and more packages have deeper dependancies on newer versions of Xorg. I always figured Portage should honour my masked packages and keep everything at the latest version without stepping on my masked packages, but it wants me to do everything manually. If package 1.2.3 is incompatible with my Xorg, I'll mask 1.2.3 and newer. There is a slight chance, however, that 1.2.4 will be compatible, but it doesn't matter, since Portage made me masked out 1.2.3 and newer, I'll never even know.
But how many allow you to view/control the display?

So not only can kids develop in an IDE in a browser, they get their own web site and do whatever they want. I recently started using it and I figured out how to render a ghetto lightbox with images pulled from my flickr feed. I used nothing but google API stuff, UiApp, etc.
