2013/2/19-3/26 [Computer/SW/OS/OsX] UID:54611 Activity:nil | 2/19 I program a lot by sshing to a Linux cluster. So I'm used to using
Xemacs to code. This works fine from a Linux or Windows workstation,
but sometimes I have to use a Mac. On Mac, the meta is usually
bound to option, but that often doesn't work over ssh for some reason.
This makes using emacs a real pain. Any suggestions on how to fix it?
(Other than "use vi")

Generic standard Linux VPS (4GB RAM): $480/year
Amazon costs more (but does offer superior scaling options).
\_ Amazon is $670 if you buy a year's usage up front (heavy util).
Why is heavy util less expensive than light util?
