This document has been obsolete since Oracle Instant Client 12.1 for OS X was released. The 12.1 client supports OS X 10.11 El Capitan, 10.10 Yosemite, and 10.9 Mavericks and can connect to Oracle Database 10.2 or later.

Look at [this document][inst] to install 12.1.

You should add the environment variable FORCE_RPATH to link with -rpath on compilation. (You have no need to set the environment variable at runtime.)

When should you use DateTime and when should you use Time?

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000

Can NAT traversal be Tor's killer feature?

tl;dr: how about a virtual global flat LAN that maps static IPs to onion addresses?

[We all know the story][1]. Random feature gets unintentionally picked up as the main reason for buying/using a certain product, despite the creator's intention being different or more general. (PC: spreadsheets; Internet: porn; smartphones: messaging.)

Facebook Perl source code from 2005. When browsing around thefacebook.com in 2005 the server spit out some server-side source code rather than running it. I believe this was for their old graph feature that let you visualize the graph between all your friends. The filename is `mygraph.svgz` and contains some gems such as a commented out "zuck" d…
