&lt;p&gt;This is a graph of the frequency of Tweets by character length (1 to 140 characters) from the 500 million Tweet sample used by &lt;span&gt;&lt;a href="http://twitter.com/redlog" target="_blank"&gt;Scott Golder&lt;/a&gt; and &lt;a href="http://twitter.com/vlad43210" target="_blank"&gt;Vladimir Barash&lt;/a&gt; (sample extracted from Twitter in late 2009) in their academic papers. View this graph in comparison to &lt;/span&gt;&lt;a href="http://thenextweb.com/twitter/2012/01/07/interesting-fact-most-tweets-posted-are-approximately-30-characters-long/?awesm=tnw.to_1CaFC&amp;utm_campaign=social%20media&amp;utm_medium=Spreadus&amp;utm_source=Twitter&amp;utm_content=Interesting%20fact:%20most%20tweets%20posted%20are%20approximately%2030%20characters%20long" target="_blank"&gt;a Twitter employee’s set of graphs that describe the typical length of a Tweet&lt;/a&gt;&lt;span&gt;. &lt;/span&gt;&lt;span&gt;Current Tweets have a number of changes (different text processing in the twitter-text API, wrapping of URLs, different application distributions, etc.) Note that the early peak seen in the current Twitter graphs is much less pronounced. Another note is that this graph shifts a little depending on how the Tweets are processed. More on that some other time.&lt;br/&gt;&lt;br/&gt;Thanks to &lt;/span&gt;&lt;a href="http://twitter.com/redlog" target="_blank"&gt;Scott Golder&lt;/a&gt;&lt;span&gt; &lt;/span&gt;&lt;span&gt;and&lt;/span&gt;&lt;span&gt; &lt;/span&gt;&lt;a href="http://twitter.com/vlad43210" target="_blank"&gt;Vladimir Barash&lt;/a&gt;&lt;span&gt; for letting me use this data. &lt;/span&gt;&lt;/p&gt;

After some testing time, I can give you the method:&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;Preheat the Sous Vide Supreme to a temperature between 120 and 140 degrees F, depending on the meat that you’re cooking (rabbit, pork, beef, etc.).&lt;/li&gt;
&lt;li&gt;Make a &lt;em&gt;&lt;a href="http://en.wikipedia.org/wiki/Beurre_mont%C3%A9" target="_blank"&gt;Beurre monté&lt;/a&gt;&lt;/em&gt; on the stove. To cook one chop, we’re using 1 lb of butter.&lt;/li&gt;
&lt;li&gt;Once the Beurre monté is emulsified and at least the temperature of the SVS water, place it in a microwave-safe cooking vessel with a water tight lid, such as BPA free tupperware-like container or a Pyrex container.&lt;/li&gt;
&lt;li&gt;Add the meat to the container. Make certain that the liquid adequately covers the meat, even at a slight angle. Add other seasonings or herbs. Shut the lid.&lt;/li&gt;
&lt;li&gt;Place the container in the SVS water and submerge it as much as possible. If desired, place a brick over it to hold it under the water.&lt;/li&gt;
&lt;li&gt;Cook the meat as you normally would in the SVS. The butter will remain at the temperature of the water.&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;Note: I take no responsibility for your outcomes with this recipe.&lt;/p&gt;</description><link>http://blog.stephenpurpura.com/post/12669589190</link><guid>http://blog.stephenpurpura.com/post/12669589190</guid><pubDate>Fri, 11 Nov 2011 21:31:08 -0500</pubDate></item><item><title>Understanding Why Stock Returns Look Like a Random Process</title><description>This is the first draft of text that I need to write for both a technical (academic PhD) audience...</description><link>http://blog.stephenpurpura.com/post/12371754609</link><guid>http://blog.stephenpurpura.com/post/12371754609</guid><pubDate>Sat, 05 Nov 2011 11:35:52 -0400</pubDate></item><item><title>Cooking with WeatherDirect.com Sensors</title><description>If you’re sitting in a house in Ithaca, NY with no furniture or cooking supplies and...</description><link>http://blog.stephenpurpura.com/post/11708808334</link><guid>http://blog.stephenpurpura.com/post/11708808334</guid><pubDate>Thu, 20 Oct 2011 18:41:50 -0400</pubDate></item><item><title>CMU Study Shows Nothing, Press Comments on It</title><description>CMU Study Shows Nothing, Press Comments on It: This article caught my eye because it talked about...</description><link>http://blog.stephenpurpura.com/post/11534339336</link><guid>http://blog.stephenpurpura.com/post/11534339336</guid><pubDate>Sun, 16 Oct 2011 14:47:38 -0400</pubDate></item><item><title>How did I know that Oil prices would drop in 2008</title><description>One of the questions that smart people ask me when they learn that I won a 2008 Forbes investing...</description><link>http://blog.stephenpurpura.com/post/11489219862</link><guid>http://blog.stephenpurpura.com/post/11489219862</guid><pubDate>Sat, 15 Oct 2011 15:30:00 -0400</pubDate></item><item><title>I Like Wrightsock</title><description>I Like Wrightsock: I’ve been wearing Wrightsock Double Layer Coolmesh socks for at least 10...</description><link>http://blog.stephenpurpura.com/post/11291348173</link><guid>http://blog.stephenpurpura.com/post/11291348173</guid><pubDate>Mon, 10 Oct 2011 18:54:35 -0400</pubDate></item></channel></rss>
