Why Vim uses hjkl keys as arrow keys
I was reading about vim the other day and found out why it used `hjkl` keys as arrow keys. When Bill Joy created the vi text editor he used the ADM-3A terminal, which had the arrows on hjkl keys.

Raw Thought: Aaron Swartz's Weblog
As we’ve discussed, in Batman Begins 1960s-style full employment and antipoverty programs lead to skyrocketing crime while in The Dark Knight Rises 1980s-style tough-on-crime policies and neoliberal economics lead to a revolt of the economic underclass.

Tail Call Optimisation in Common Lisp Implementations
While the Common Lisp standard does not require implementations to eliminate tail calls, some do—thereby allowing a more functional programming style. Especially in the prototyping phase, it can be useful to know where this functional style can be employed and where it's likely to cause stack overflow. Since I…
