+  <abstract>
+    <p>
+      How do we make dynamic languages fast? Today, modern Javascript engines
+      have demonstrated that programs written in dynamically typed scripting lan-
+      guages can be executed close to the speed of programs written in languages
+      with static types. So how did we get here? How do we extract precious type
+      information from programs at runtime? If any variable can hold a value of any
+      type, then how can we optimize well?
+    </p>
+    <p>
+      This talk covers a bit of the history of the techniques used in this space, and
+      tries to summarize, in broad strokes, how those techniques come together to
+      enable efficient jit-compilation of dynamically typed programs.
+      To do the topic justice, Kannan Vijayan will be talking the Monday and
+      Tuesday March 9th and 10th.
