Ruby Weekly News is a summary of the week's activity on the ruby-talk

It's a shortie newsletter this week. (Paradoxically, the more threads on the
list, the shorter the newsletter.)

Quote of the Week
=================
* rue teaches piglet about symbols on #ruby-lang
------------------------------------------------
James Britt:
| "When I use a symbol," Humpty Dumpty said, in a rather scornful
| tone, "it means just what I choose it to mean - neither more nor
| less."
| "The question is," said Alice, "whether you can make symbols mean so
| many different things."
| "The question is," said Humpty Dumpty, "which is to be master -
| that's all."

Packing (#62)
-------------
Ruby Quiz this week comes from Ilmari Heikkinen: write a program to pack
boxes of different dimensions as tightly as you can.
Regexps: Perl vs. Ruby
----------------------
Sam Dela Cruz inquired why the regular expression /^[\d\.]+$/ matched
differently in Perl and Ruby. David A Black responded, "^ and $ match
start and end of line, not string. For start and end of string, you want
\A and \z (or \Z to ignore final newline)."
String#split, respecting quotes?
--------------------------------
Richard Livsey asked how to split a string %Q{some words "some quoted
text" some more words} into an array ["some", "words", "some quoted text",
"some", "more", "words"]. Solutions using regexps flew in. Tim Hearney
noted that the CSV module can do just that:
require 'csv'
CSV:
arse_line('some words "some quoted text" some more words', ' ')
Florian Groß pointed out the Shellwords module. Both have their
advantages.
Postgres-ing? Too many choices!
-------------------------------
Dave Howell found three different gems for talking to PostgreSQL
databases: postgres, postgres-pr and ruby-postgres.
What's the difference between them?
Dave Lee said that postgres and ruby-postgres are in fact the same project
- the latter is the newer name of it.
postgres-pr is a "pure Ruby" library that doesn't need PostgreSQL's libpq
native library (but has fewer functions than ruby-postgres, which wraps
the native library).
