How to get marginal effects with "mvrs"

I found this very helpful post by Ryan sometime ago about how to get marginal effect from estimated models with "mvrs" command, very helpful.

Stata 12

There are two things I like Stata 12 most: (1) automatic memory management, and (2) a decent program editor for Linux (I know the editor has been available on the Windows platform since version 11, but I am a Linux person). The updated "margin" commands also look good.

The Linux version of the OpenGeoDa seems to be more stable than the Windows version: I was able to open some shape files with Chinese file names under Ubuntu Linux but not under Windows 7 (simply crashed).

Updated on August 18. 2011: 

Now the problem is that OpenGeoDa does not seem to run on Ubuntu 11.04 64-bit: no error messages and no hints, really weird...

Mint Linux Debian edition

It is highly regarded here, and may provide a way from Ubuntu to Debian.

Here is another positive review.

Gnome 3 looks nice

I tweaked my ubuntu 11.04 and replaced the default window manager with Gnome 3. It took a while to get used to it but eventually I like it a lot. I think part of the reason ubuntu is turning to unity instead of the old gnome2 is that the new gnome represents such a drastic shift away from the old gnome2, which is no longer under active development.

The overall experience is positive. I expect the next release will get rid of the few annoyance such as the lack of easy-to-use configuration tool to tweak things like screensaver, sound, etc.
