Changes

• Fixed bug where missing intermediate file dependencies could cause an abort with —trace or —dry-run. (Brian Chandler)
• Recursive rules are now supported (Tilman Sauerbeck).
• Added tar.gz and tar.bz2 support to package task (Tilman Sauerbeck).
• Added warning option for the Test Task (requested by Eric Hodel).
• The jamis rdoc template is only used if it exists.
• Added fix for Ruby 1.8.2 test/unit and rails problem.
• Added contributed rake man file. (Jani Monoses)
• Fixed documentation that was lacking the Rake module name (Tilman Sauerbeck).

What is Rake

Rake is a build tool similar to the make program in many ways. But instead of cryptic make recipes, Rake uses standard Ruby code to declare tasks and dependencies. You have the full power of a modern scripting language built right into your build tool.

Availability

The easiest way to get and install rake is via RubyGems …

  gem install rake    (you may need root/admin privileges)

Otherwise, you can get it from the more traditional places:

Thanks

Lots of people provided input to this release. Thanks to Tilman Sauerbeck for numerous patches, documentation fixes and suggestions. And for also pushing me to get this release out. Also, thanks to Brian Chandler for the finding and fixing —trace/dry-run fix. That was an obscure bug. Also to Eric Hodel for some good suggestions.

You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible. Most startups that fail do it because they fail at one of these. A startup that does all three will probably succeed.

And that’s kind of exciting, when you think about it, because all three are doable. Hard, but doable. And since a startup that succeeds ordinarily makes its founders rich, that implies getting rich is doable too. Hard, but doable.

If there is one message I’d like to get across about startups, that’s it. There is no magically difficult step that requires brilliance to solve.

 With these changes, it doesn't require '*NIX', but will accept "Linux"
 or "Unix", and it is a bit more accepting of various database keywords.

fhtr.org/projects/ihelp/ fhtr.org/projects/ihelp/doc/ fhtr.org/projects/ihelp/releases/ihelp-0.3.0.tar.gz

This release brings with it custom help renderers, which you can leverage to render help whenever you want, wherever you want and however you want.

Also included are a couple experimental renderers (no guarantees):

• #rubydoc_org opens the corresponding ruby-doc.org class help file using the program defined in IHelp::WWW_BROWSER
• #rubytoruby_src uses Ryan Davis’ RubyToRuby class to print out the source for the method.

blog.zenspider.com/archives/2005/02/rubytoruby.html for more info about RubyToRuby.

Ri bindings for interactive use from within Ruby. Does a bit of second-guessing (Instance method? Class method? Try both unless explicitly defined. Not found in this class? Try the ancestor classes.)

Goal is that help is given for all methods that have help.

Examples:

  require 'ihelp'

  a = "string"
  a.help
  a.help :reverse
  a.help :map
  String.help
  String.help :new
  String.help :reverse
  String.help :map
  String.instance_help :reverse
  String.instance_help :new # => No help found.
  a.help :new
  help "String#reverse"
  help "String.reverse"
  a.method(:reverse).help # gets help for Method
  help "Hash#map"

Custom help renderers: The help-method calls IHelp::Renderer’s method defined by IHelp.renderer with the RI info object. You can print help out the way you want by defining your own renderer method in IHelp::Renderer and setting IHelp.renderer to the name of the method.

 require 'ihelp'

 class IHelp::Renderer
   def print_name(info)
     puts info.full_name
   end
 end

 IHelp.renderer = :print_name
 [1,2,3].help:reject
 # Array#reject
 # => nil

FreePop is a computer game based on the classic Populous I and II games by Bullfrog Productions. It is currently in development and aspires to be a great improvement on the original games, being a fitting gift to the open source community, as well as a part of the open source community.

freepop.sourceforge.net

OK, So What’s Populous?

For those of you who were trapped in a small dark room during the late 1980’s and 1990’s, or otherwise similarly deprived, Populous is a series of games developed by Bullfrog Productions which created the god-sim genre. The premise is that you (the player) and your opponent (AI or human) are gods or equivalent deities, and you battle each other using your powers - such as the summoning of natural disasters and the ability to coax the will of your followers - in order to destroy the followers of the opponent. The winner is the god with remaining followers.

Some shots of Populous II:

The amazing thing is that it is soooo true :-).

 "Toyota Japan rejects ISO 9000"
 "My thanks to Takaji Nishizawa, a leading industrial consultant in
 Japan, for this item:

 >>
 "The following was reported in Nikkei Business. Nikkei Business is
 published weekly and one of the most popular business journals in
 Japan.

 "In October of 1999 it featured a three-week series about ISO 9000
 problems in Japan. In the articles it said that Toyota decided not to
 get ISO9000 because it saw no value in terms of quality and thus saw
 no need to register.

 "The decision had been made after the Shimoyama factory, which is an
 engine plant, had registered to ISO9001. When introducing new things,
 Toyota's philosophy is to test actually before installation rather
 than discuss on the desk. The Shimoyama factory had been selected as
 a test plant.

 "And after the test, Toyota concluded there was no value in ISO9000
 registration."

 There was a newspaper reporter in Philadelphia (over 10 years ago) who
 reported the observation that a company that manufactures concrete life
 preservers could maintain their ISO-9000 certification so long as they
 followed a documented process for notifying the next of kin.

Ron Jeffries posted:

 My limited experience is that many companies who go ISO do so for
 one or both of these two reasons:

 1. They are a supplier to a company that requires it;
 2. They believe it will improve their ability to market their
 products or services.

 I am sure there are companies that go ISO in order to improve, but
 I've not personally encountered one. (I did once encounter a company
 whose CEO had promised the board to get to CMM 2 by some date, IIRC
 as a response to low quality from his software teams.)

www.erikveen.dds.nl/distributingrubyapplications/index.html

This URL points to the place where I’ve dumped my thoughts about building, packing and distributing Ruby applications. Theory and practice. The ultimate goal is to be able to distribute just one executable which contains both the application and the Ruby interpreter.

That’s achieved by the combination of Tar2RubyScript [1] and RubyScript2Exe [2].

It’s definitely worth reading if you have to distribute your Ruby applications!

As announced in the Apache News Blog that there will be no further work to develop Struts 2.x.

 From: Chris Pine <cpine@hellotree.com>
 Newsgroups: comp.lang.ruby
 Subject: [ANN] Ruby 2.0!
 Date: Mon, 24 Jan 2005 02:29:57 +0900

 Big news!

 Ruby 2 (a.k.a Ruby Secunda Kathrine Pine) was released January 22, 2005
 at 1:51:42 pm (PST) after a few hours of intense, last-minute debugging
 and deployment.  We've been working on this project for just over 9
 months and are quite pleased with the results!  (Well, my wife really
 did most of the work, though I *did* play a seminal role in the initial
 project conception phase.)

 <<< THE NAME >>>

 Ruby     -- named after our favorite language, of course!
 Secunda  -- our second child (after C), and the second Ruby
              (in the roman tradition of numbering your children,
                          e.g. "Quintus" and "Octavius")
 Kathrine -- named after the lead programmer on this project
             (a tradition in her ancestral development house)
             Pine     -- yes, our last name, but also Matz once told me that
                          "matz" is Japanese for "pine"!

 <<< FEATURES >>>
 * Powerful audio output (even on those little tweeters)
 * Net Wt. 9 pounds (or a little over 20k carats as Dave Thomas notes)
 * FIFO digestive queue
 * Ruby.length == 20 inches
 * UNBEATABLE copy protection
 * Dark brown hair
 * Just plain FUN!  (true to the Ruby lagacy)

 <<< KNOWN ISSUES >>>
 * FIFO queue occasionally behaves like a LIFO stack
 * Ruby.sleep(ALL_NIGHT) seems to resume unexpectedly
 * While C (her big brother) sends plenty of messages to Ruby,
   Ruby doesn't seem to respond to C calls.

 <<< SCREENSHOTS >>>
 Screenshots will soon be available here:
 http://pine.fm/FamilyPictures/?page=filter&year=2005&month=1

 Currently, though, we've only put up our pre-release screenshots (and
 around 4000 pictures of C).

  <<< DOWNLOADS >>>
  You wish!
  :)
