    Articles and Announcements

    * "Learn to Program" is now available

    Dave Thomas: "Just a quick note to say Chris Pine's new book, Learn to
    Program, is now available and shipping."

    Surgeon asked how it relates to the online version that's been around
    a while, and Dave Burt said that the online version's good, but the
    book is better.

    * JRuby at JavaOne 2006

    Charles O Nutter and Tom Enebo will be giving a JRuby presentation at
    the JavaOne 2006 conference.

    "We should have most of the milestones I talked about at RubyConf
    completed, and oughta have plenty more cool demos to run. If all goes
    well, we may have Rails running under JRuby too."

    (JRuby is a Ruby interpreter written in Java. It also provides
    interoperability between Ruby and Java code - the two (?) Ruby-Java
    bridges being an alternative approach.)

    * Calling all Freebsders.

    Dick Davies posted a heads up for FreeBSD users; the ports tree is
    going to include 1.8.4 "Any Day Now". It has been at 1.8.2 for a

    Luc Heinrich noted that DarwinPorts has recently done the same.

    User Group News

    * Stockholm User Group

    Dr Nic asked if Stockholm had a Ruby User Group, and everyone said no,
    but that'd be cool, and they met on January 19th at a restaurant
    called "Grill Ruby".


    Script's Parent Directory

    Chris Newman was "looking for a Ruby equivalent to Perl's FindBin module,"
    which returns the directory containing the running script (as opposed to
    the current working directory). Austin Ziegler replied that
    File.dirname(__FILE__) gives you this.

    thousandth separator

    bmgz is in need of a library for formatting numbers with thousandth
    separators, e.g. 1000000.00 becomes "1,000,000.00".

    Gene Tani posted a couple of options: a one-liner "snippet", and the
    flexible Numeric#format_s from Gavin Sinclair's Extensions library.

    Delaying Quote Expansion

    Kevin Olbrich asked how to delay double-quoted expansion of "string
    #{variables}". Eero Saynatkari mentioned this simple method:

    str = '"Value #{foo}"'
    foo = 123
    eval str #=> "Value 123"

    James Edward Gray II pointed to ERB, the standard templating library
    included with Ruby.

    require 'erb'
    str = 'My number is <%= bar %>.'
    bar = 1986 #=> "My number is 1986."

    get the name of the day from

    misiek wanted to get the current day of the week as a name like Mon
    instead of the number returned by t.wday (where t =

    Antonio Cangiano suggested t.strftime("%a") for "Mon" and t.strftime("%A")
    for "Monday". (strftime = String-format-time.)

    "ri strftime, will give you the complete list of options."

    Another option is to require 'time' then Time::RFC2822_DAY_NAME[t.wday].

    New Releases

    Rake 0.7.0 Released

    Jim Weirich added some interesting features to the Rake build tool,
    including parallel execution of pre-requisites and namespace support for
    task names.

    TeensyWeb 0.2.0

    From Jon A. Lambert, TeensyWeb 2.0, "a combination Wiki, Forum and
    Subversion Repository browser".

    Now with installation documentation and RSS feeds.

    Radius 0.0.1 -- Powerful Tag-Based Templates

    John W. Long was pleased to come out with Radius, "a small, but powerful
    tag-based template language for Ruby inspired by the template languages
    used in MovableType".

    Nathaniel S. H. Brown: "Nice work. Would love to see a .rad extension for
    Rails at some point :)"

    RMagick gets face-lift, book and movie deal

    Timothy Hunter released RMagick 1.1.0, the Ruby interface to the
    ImageMagick and GraphicsMagick image processing libraries. It also
    includes a 2D drawing API.

    One of the new methods is Image#vignette, which was originally an RMagick
    example program, but has now made its way into ImageMagick itself :)

    All known bugs were fixed, crop_resized added for creating thumbnails, and

    In other RMagick news,

    | Apress's new book, The Definitive Guide to ImageMagick, by Michael
    | Still, devotes a chapter to using ImageMagick from Ruby programs via
    | RMagick.


    rubikitch created a tool called Test::Unit::Benchmark, used for showing
    how long each unit test took to run.

    "Because this program is very short, it is an easy example of AspectR,
    aspect oriented programming for Ruby."

    TeensyMUD 2.7 released - Baby Got Back!

    "Baby Got Back" said Jon A. Lambert, announcing TeensyMud 2.7, "the
    original only ruby mud with smoking hot T&A action".


    rubikitch, announcing yet more software, introduced `ppp', an alternative
    to Kernel#p, with ppp, pppp, ppm and ppmp commands.

    All for debugging.

    Nitro + Og 0.27.0 Client code, WebFile, Elements improved, New ...

    George Moschovitis released new Nitro and Og versions.

    Nitro is a web application framework and Og an object-relational database
    mapping library.

    As usual with these releases there are a huge number of interesting
    features, including "groundbreaking client side action/scripting support",
    where you write Ruby code that results in Javascript.

    "A domain specific language is provided for the client action to implement
    stuff like ajax async updates, scriptaculous visual fx and more."

    This support also includes "morphers", which enable you to set properties
    like draggable="true" and "auto_complete="true" on HTML input tags to
    cause mystical wonders to occur.

    A WebFile system was also added, to make it easy to upload files.

    Lots lots more.

    George: "The latest Nitro/Og releases are a real community effort ;-)"

    Librend 0.4

    Ilmari Heikkinen released version 0.4 of Librend, a realtime graphics
    rendering library for Ruby.

    It uses SDL, and also supports sound.

    FreeRIDE 0.9.5 - The Free Ruby IDE

    The release of FreeRIDE 0.9.5 was heralded by Laurent Julliard.

    Thanks to Jonathan Maasland for the new `projects' support, and to Martin
    Leech for quick keystrokes to comment/uncomment blocks of code. Many
    usability enhancements were also made.

    "FreeRIDE aims to be a full-featured, first-class IDE on a par with those
    available for other languages, with all the best-of-breed features that
    you would expect in a high-end IDE."


    rubikitch set forth irbsh, an extension of irb/inf-ruby.el for Emacs.

    "You can easily execute shell commands and Ruby codes by using irbsh."

    Mongrel 0.1.0 -- A Fast As Hell Mostly Ruby Web Server

    Zed Shaw released "a mostly Ruby webserver" called Mongrel. It's fast, but
    allegedly cannot yet yet bake cheddar.

    Now for the fun (and surely flamewar generating) statistics on how it
    compares to WEBrick:

    WEBrick/Linux: 175 req/sec
    Mongrel/Linux: 1350 req/sec

    WEBrick/OSX: 5.3 req/sec
    Mongrel/OSX: 304.4 req/sec

    There weren't yet any flames, so we've put the quote in an emotionally
    coloured box to try and stir things up. (That'll be asterixes for you
    plain-text fellas. Pretend they're masking swear words from Zed for the
    same effect.)

    0.1.1 was later released, adding the "It Works Now, Maybe" feature.

    RedHanded chipped in with comm'try.


    Henrik Martensson introduced Test::Unit::XML, which adds assertions for
    checking XML documents.

    RubyCLR first drop

    John Lam announced a new Ruby / .NET bridge called RubyCLR.
    Generics aren't yet supported, but it's a "super high priority item".


    Ruby-GetText-Package now has a Greek locale (by damphyr), bugfixes and
    support for Rails tests.

    Masao Mutoh: "Thanks to: Kazuhiro NISHIYAMA, Nick Snels, damphyr, Karel

    ICU4R 0.1.0 - initial release

    Lugovoi Nikolai let the initial release of ICU4R out of the bag.

    "ICU4R is an attempt to provide better Unicode support for Ruby, based on
    ICU library."

    FarPy GUIE v0.4

    FarPy GUIE, used for graphically designing wxWidget GUIs, now supports

    Thanks for reading!

    Customer: "How much is a large order of Fibonaccos?"
    Cashier: "It's the price of a small order plus the price of a medium order."
