(cons )
a slide intentionally left blank
widgets the cornerstone
{:fetch (fn [env] (get-data-for env)) :view (fn [fetched-data] (render fetched-data))}
(map render widgets) ↓ (pmap render widgets)
templating worst nightmare

<div id=”main”> text </div> {:tag :div :attr {:id ”main”} :content
[”text”]}
repl everywhere
tools to the rescue
before 54 machines
after 10 machines* * traffic grew twofold
mistakes we made a lot
(my {:yet :another} (somewhat [:helpful]) (dsl!))
hiring not as bad as it seems
future a lot to be done
summing it up it was a good idea
