[mike.tig.as][mta] server configuration

This gist contains the nginx and tor configurations for the [mike.tig.as][mta] servers, mainly to show:

Use of the chris-lea/nginx-devel PPA to allow use of SPDY.
ssl_ciphers selection to mitigate BEAST attack, enable [perfect forward secrecy][pfs] if possible and select the strongest possible ciphers within those bounds. (Exception is made for several ciphers at the end of list, for compatibility reasons.)

Say you have an SVG built dynamically on the client by D3. Now say you want to save it to a static PNG as a fallback for old browsers. There are lots of ways to do this using alternative renderers (such as Batik and PhantomJS), but what if you want your browser to do it, so that you the static PNG matches the dynamic SVG exactly, down to the subpixel, including transparency?

Here’s how.

1. Save as SVG.

Use the SVG Crowbar bookmarklet to save the SVG to a file. Call this file “fallback.svg”. Open the SVG in your browser to verify that it looks right.

SVG Crowbar helpfully inlines any stylesheets you may have on the page, but you might find you need to edit a few of the styles by hand to get things to look right. For example, the font-family “sans-serif” won’t work in an SVG image, even though it works when the SVG is built client-side; you’ll have to make the font name explicit, s

	// How to use this:
	// 1. Go to the desired profile page on coderwall, like http://coderwall.com/marcinbunsch
	// 2. Paste this gist in the JS console
	//
	// You can also probably use this in greasemonkey and dot.js
	//
	// Also, it was tested in Chrome, Firefox and Safari, it probably will
	// not work in IE, but I just don't care about it ;)
	//
	// UPDATE: Coderwall made changes to the site and I cannot retrieve the achievements, so they are hardcoded, taken from a cached version of the achievements page

	# An example of basic real-time, single-room broadcast chat using Server Sent
	# Events in plain old Rack. This example does NOT use hijack, or the async
	# hacks, it just relies on a well implemented threaded Rack server (at time of
	# writing this will therefore only work with puma!). Other servers should be
	# fixed to support this, as it is pretty critical to how Rack should work on
	# most servers. The only spec-acceptable failure in this case is not flushing
	# the content stream on each yield (for which the rack spec has no workaround
	# today).
