# It was inspired by a number of individuals and makes use of some of their ideas
#     1. FastML.com got me thinking about inline processing after

#     2. John Lanford and his fantastic Vowpal Wabbit library. 
#        Check out his NYU video course to learn more (see below)

Remote, Office Not Required

The Time is Right for Remote Work

Why work doesn't happen at work

The office during the day has become the last place people want to be when then really want to get work done.

Offices have become interruption factories: it's just one interruption after

Erlang Tracing: more than you wanted to know

Rough Outline

• What can be traced?
• How can trace events be specified?
• "match specifications": twisty passages, all alike
• WTF, can I just use DTrace and drink my coffee/beer/whisky in peace?
• Trace delivery mechanisms: pick one of two

HOW TO INSTALL

Put flip somewhere in your $PATH and chmod a+x it.

Copy fuck into ~/.bashrc.

I was able to install FreeBSD on GCE in a very direct way, without the hurdles of Qemu, gcutil, and the FreeBSD installer. All are great tools, but I think my apporach is somewhat more suitable for GCE, or at least much simpler. Much of this is well-known practice for installing manually, with some fluff for managing it as a disk image, as well as the few odd networking requirements of GCE (MTU and netmask).



My basic approach is to:

* Use my FreeBSD machine at home to build a self-hosting "rescue" disk image for GCE.

* Start a temporary Linux machine in GCE from a provided image.
