# along the way.

# The #1 issue you are likely to encounter is with Homebrew or Python packages whose
# binary components link against system Python. This will result in runtime segfaults,
# especially in rviz. If you suspect this is occurring, you can attempt to remove and
# reinstall the offending packages, or go for the nuclear option--- empty your Cellar
# and site-packages folders and start over with brewed python from the beginning.

How to cross compile Go with CGO programs for a different OS/Arch

It is possible to compile Go programs for a different OS, even though go build says otherwise.

You'll need:

• a valid toolchain for the platform/os you're targetting
• Go Tip (works on 1.1 and 1.2rc1 but you might as well be on tip)
• golang-crosscompile helper script https://github.com/davecheney/golang-crosscompile
• the patch provided

You can now create a spinner using any of the variants below:

$("#el").spin(); // Produces default Spinner using the text color of #el.
$("#el").spin("small"); // Produces a 'small' Spinner using the text color of #el.
$("#el").spin("large", "white"); // Produces a 'large' Spinner in white (or any valid CSS color).
$("#el").spin({ ... }); // Produces a Spinner using your custom settings.

$("#el").spin(false); // Kills the spinner.

# here's a quick recipe to run a performance test
# with this method, you can:
 #-> easily choose the examples you want included from your existing specs
 #-> define the target number of total iterations you'd like, no limit
 #-> tune the transaction mix by specifying frequency metadata for each example
 #-> be happy that the transaction mix is fairly homogeneous over the test interval

# (ideally you'd run this with acceptance (webrat/capybara) specs, but you
# could employ this technique for any rspec test)
