Re: [FRIAM] UTAustinX: UT.5.01x: Linear Algebra - Foundations to Frontiers | edX
Here’s a new slogan off the top of my head: “If it isn’t virtual, it isn’t real.” :-) I use VMWare Fusion on my MacBook Pro, although I’ve generally been impressed with VirtualBox (the price is certainly right). Lately, I’ve been using a VM within a VM. I need to maintain an app on some Windows boxes, but don’t have one myself (don’t want one). To maintain the app, it is easiest to give them a solution that runs in a VM in one of said Windows boxes. To do so, I run Windows on my Mac inside Fusion. I then tried running Ubuntu under VirtualBox in this virtualized Windows box, but Ubuntu wouldn’t boot. It could be that if the outer host (i.e. my Mac) were running VirtualBox instead of Fusion, it would work, but I haven’t tried that. Instead, I run VMWare Player (the free, as in beer, not as in freedom, software) inside this virtualized Windows box and Ubuntu runs fine there. Surprisingly good performance, for a simple LAMP stack running in this double virtualized environment. Anyway, life without virtualization would be a whole lot less interesting.

Great input, thanks! I admit to being a browser fan-boy just because, beyond needing a modern browser, its config-free. But I'm definitely open to zero-config of any sort. Will report. BTW: The linear algebra course the MOOC is modeled after uses Strang's Linear Algebra. Tom: (10/11/09) you're right, it IS idiosyncratic but I found it compelling, the parts I followed from his video lectures and using his book. -- Owen On Fri, Dec 6, 2013 at 11:56 AM, Gary Schiltz g...@naturesvisualarts.comwrote: Here’s a new slogan off the top of my head: “If it isn’t virtual, it isn’t real.” :-) I use VMWare Fusion on my MacBook Pro, although I’ve generally been impressed with VirtualBox (the price is certainly right).

I am subscribed to a MOO programmers list, and someone offered a Vagrant file for MOO tools; so besides eliminating dependency problems it can be used to giftwrap goodies. However, virtualisation still takes a little setting up and although performance has improved considerably in recent times older machines (to address the same ethic as 'offline first', namely do not design primarily for the most well-prepared users) might balk. A liveboot image seems a nice alternative. -Arlo FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com
