wrote up his impressions of Ruby in a blog post Ruby, PHP and a
Conference.

"The result: there are definitely some very cool things here. I don't

Watir overview.

setting one up?

Threads
=======

Printing RFC3339 timezone?
--------------------------

csn asked how to turn a Time into some text suitable for use in an Atom
XML feed, i.e. following RFC3339.

Bob Showalter posted a link that describes the 'xmlschema' method, and
Austin Ziegler gave the same response a minute later.

require 'time'

t = Time.now
t.xmlschema # => "2006-01-31T22:09:20+13:00"

Making Thumbnails with RMagick
------------------------------

Timothy Hunter noticed that a lot of people were using RMagick to make
thumbnails of JPEG images, so he benchmarked four different resize methods
(for speed, simplicity, and quality).

The overall winner was the `thumbnail' method. That's easy to remember :)

PostgreSQL in Ruby with SSL connections
---------------------------------------

Kevin Brown asked how to connect to PostgreSQL through SSL, and Dick
Davies replied, saying that if he uses the ruby-postgres library (which
wraps the C client library), then this is handled "transparently" as far
as the Ruby library is concerned: you just need to put the appropriate
certificate/key files in the ~/.postgresql directory.

Kevin later managed to get this working via psql, but the Ruby code was
giving the error #<PGError: SSL error: sslv3 alert handshake failure>.

Any ideas?

I like the new ruby-doc.org!
----------------------------

James Edward Gray II said "I feel the new front page of ruby-doc.org is
significantly more attractive. Nice work!"

ruby-doc.org creator and maintainer James Britt gave credit for the
redesign to Dan Ritz of 30 Second Rule.

Maxwell Heidegger asked if it was using Rails, and the answer was no: it's
using Nitro.

Port a Library (#64)
--------------------

James Edward Gray II introduced an unusual theme for Ruby Quiz this week:
port a small, simple library of your choosing from another language to
Ruby.

Strange posting about ebooks
----------------------------

Lots of people on the mailing list received an 18mb email containing a
number of unauthorised Ruby e-books.

They were displeased.

how to run just one test method in a test case
----------------------------------------------

nicknameoptional had some unit tests, and wanted to know if there is a
command to only run a particular test method.

Marcel Molina Jr. said that the "-n" command-line option is used for this.

It takes either the whole method name, or a pattern to match a set of test
methods.

ruby tc_foo.rb -n test_foo_1
ruby tc_foo.rb -n /foo_2/

wxruby 2
--------

baalbek wondered about the status of wxruby2, and Alex Fenton said it's
close to being ready for beta release, but there are some important bugs
that need fixing.

| There is a good group of C++ developers involved who made a lot of
| progress over last summer, but they've all been short of time in the
| last few months, so been a lull in development.
|
| It's usable enough for playing around, and has some nice new features
| beyond 0.6.0 - on top of all the native look'n'feel niceness of Wx
| generally - such as good support for OS X (inc aqua-look), Unicode, new
| widgets, and better exposing of Wx class hierarchies. Unlike 0.6.0
| release from the old series, I wouldn't say it's stable enough for
| production code.

New Releases
============

xx-0.1.0 : xhtml and xml make it twice as dirty
-----------------------------------------------

Ara.T.Howard:

| xx is a library designed to extend ruby objects with html, xhtml, and
| xml generation methods. the syntax provided by xx aims to make the
| generation of xml or xhtml as clean looking and natural as ruby it self.

In a subsequent post Ara compared this library with the XML builders used
in Nitro and Rails.

One-Click Ruby Installer 184-16 preview1 is available!
------------------------------------------------------

Curt Hibbs posted preview1, then preview2 of the Windows One-Click Ruby
Installer for Ruby 1.8.4.

There was much rejoicing.

Adam Sanderson: "Thank you so much for your work on the one click
installer. It makes using ruby in my office feasible, which makes me
sane(ish)."

Mongrel HTTP Server 0.1.2 (With Camping Tepee Sample)
-----------------------------------------------------

Zed Shaw announced a new release of his "fast as hell web server library",
Mongrel.

"Remember, this is totally ALPHA work. Don't run a nuclear reactor with
it, but do shoot me crashes, bug reports, anything."

Sudoku - Dancing Links algorithm
--------------------------------

jwesley wrote a Sudoku game in Ruby / GTK+, and also released a gem for
his implementation of the "Dancing Links" puzzle-solving algorithm.

Laughed out loud at that. In case I haven't said it before, thanks for
the time and effort you put into this!
