Threads
SimFrost (#117)
---------------
James Edward Gray II posted this week's Ruby Quiz. "This was one of the
Perl Quiz of the Week problems a couple of years ago. It's also my
favorite computer simulation."
Create a simulation of frost, following the (given) rules that describe
how to iterate the animation. "Again, use whatever output you are
comfortable with, from ASCII art in the terminal to pretty graphics."
What is Ruby Quiz? From the website:
> Ruby Quiz is a weekly programming challenge for Ruby programmers in the
> spirit of the Perl Quiz of the Week. A new Ruby Quiz is sent to the Ruby
> Talk mailing list each Friday. (Watch for the [QUIZ] subject
> identifier.) After a 48 hour no-spoiler period has passed, everyone is
> invited to contribute solutions and/or discussion back to the list. The
> following Thursday a Summary will be sent to the list, discussing the
> quiz, solutions and discussion. The next day, the cycle begins again.
It's a great way for new and experienced Ruby programmers alike to try
their hand at problems, and get feedback from others.
Duck Typing Hash-Like Objects
-----------------------------
Gary Wright asks for ideas on the best way of identifying a "hash-like"
object, so that the check relies only on the interface, as in duck typing.
Various suggestions were put forward including the detection of the
to_hash method, using #fetch and the discussion also careered through the
meaning of duck typing.
If you want to know more about hash behaviour and/or duck typing you could
do a lot worse than reading this thread.
Ruby.on-page.net - Evolution began
----------------------------------
A flurry of feedback greeted ruby.on-page.net, an online Ruby
documentation site featuring a novel interface.
The idea appears to be help offered on a single page with wiki-like
attributes. Give it a shot and see what you think.
Yahoo!'s Ruby Developer Center
------------------------------
Brian Adkins ran into Yahoo!'s Ruby Developer Center and thought it looked
interesting.
"Nice heads up", concluded Richard Conroy.
the name of Matz
----------------
In this thread you'll find Matz' name in Kanji, how to pronounce "Yukihiro
Matsumoto", and a discussion of naming conventions to distinguish given
and family names.
Following a comparison with Matz' non-capitalisation of his family name,
Akinori MUSHA said "Although passports and other formal documents may have
restrictions, one should be allowed to spell one's name as one wants, so
long as it is used consistently and serves as social identification."
why the lucky stiff's name was also dissected, with Wilson Bilkovich
reckoning that the underscore in _why "represents the intake of breath
before speaking his name".
Matz said (without joking) "I've heard that it's his REAL first name", and
Hal Fulton backed up the rumour - he'd heard it was based on a younger
sibling's alternative to _why's real first name; "Wyatt or something".
New Releases
Rassmalog 3.1.0 - the mutant
----------------------------
Rassmalog is a blog engine based on RSS 2.0, YAML and Textile. By the end
of the thread v3.0.0 had mutated into v3.1.0, so it's definitely under
active development.
JRuby 0.9.8
-----------
The JRuby folks are obviously busy as there is yet another release for
your delight. Highlights here are the Rails support (say goodbye to
irksome WAR deployments 
which the developers reckon is good enough for
testing.
ActiveWarehouse ETL 0.6.0
-------------------------
Check out the latest release of ActiveWarehouse's Extract, Transform and
Load project. Gem goodness is included and there are a "slew" of new and
improved features. Definately one for Ruby in the Enterprise folk.
rcairo 1.4.0
------------
The ruby wrapper for the Cairo library was released this week. This
release has emphasis on performance and PDF output. Also some
standardisation with Ruby-GNOME2 has occurred.
memcache-client 1.3.0
---------------------
The pure Ruby client for memcached has been released. Patches and new
functionality appear to be the order of the day. So if your DB development
lacks a certain dash of speed, why not give this a shot?
Instant Rails 1.6, with MySQL 5
-------------------------------
Instant Rails now includes MySQL 5. The Instant Rails installer is an easy
way for Windows users to get up and running with a Rails development
environment.
Curt Hibbs: "Many thanks to Jirka Pech who made the MySQL upgrade
possible."
Ruby ORBit2 (CORBA)
-------------------
Max Lapshin implemented preliminary support for the ORBit2 library (for
CORBA).
"No IDL is required at all: all information about method calling can be
accessed via CORBA reflection mechanism."
New "Ruby for Windows" Installer
--------------------------------
Lothar Scholz posted a new Ruby installer for Windows, as an alternative
to the widely-used One Click Ruby Installer, with a different philosophy
as to which packages should be included in the base install.
> Everything is compiled with MSVC 6.0, so it is compatible with the one
> click installer and all the "msvcrt" binary gems.
Rack 0.1, a modular Ruby webserver interface
--------------------------------------------
Christian Neukirchen released Rack, a webserver and framework interface
for Ruby. It is based on Python's WSGI and PEP333, and he believes it will
bring a lot to the Ruby web community.
> Rack provides a minimal, modular and adaptable interface for developing
> web applications in Ruby. By wrapping HTTP requests and responses in the
> simplest way possible, it unifies and distills the API for web servers,
> web frameworks, and software in between (the so-called middleware) into
> a single method call.
With the Rack standard, any Rack compatible framework (Rails, Camping,
custom, more to come) will work with any Rack supported web server
(Mongrel, WEBrick, FCGI, CGI).
This means that we would need to develop just one Rack adapter per
framework, and one Rack handler per webserver. Currently, each framework
has to implement its own support for each web server.
