# This is a code example for the Ruby HTTP library Typhoeus

# here's an example for twitter search
# Including Typhoeus adds http methods like get, put, post, and delete.
# What's more interesting though is the stuff to build up what I call
# remote_methods.

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}

" When I'm editing some LaTeX, I use PDF files to handle any inserted images and
" LaTeX has some difficulty lining them up right, so I explicitly state the
" viewport.  To get the bounding box from the PDF file, I have a script called
" 'getbb'.  This function is /very/ specific to my needs.  It pulls the filename
" from the current line, which always looks something like this:
"
" \includegraphics[scale=0.5, viewport = 40 39 703 153]{target/filename.pdf}
"
" Pulls out the filename (i.e. target/filename.pdf), runs 'getbb' on that and
" inserts the output back overtop of the "viewport = 40 39 703 153".
