Papers I like Pt. 1 Papers I like Pt. 2

Let's start meta:

1. Lamport - State the Problem Before Describing the Solution (1978). … 1-page memo. Read it.
2. Herlihy - Wait-free synchronization (1991) … Truly seminal. Lucid + enough good ideas for 4 papers easily.
3. Cook - How complex systems fail (1998) … 4 pages that anyone working on/with complex systems should read.

<roc> basically, IsActive() is true when the document is associated with a GlobalWindow(inner) which is the current document in its docshell
<roc> i.e. not bfcached
<roc> IsVisible() is similar but more specifically delimited by the pageshow and pagehide DOM events
<roc> Hidden() is like !IsActive() but all documents associated with hidden tabs are also Hdden()
<roc> tabs/docshells have this "hidden" state; all Firefox tabs that aren't the topmost tab are marked hidden
