We'll be meeting in Collective Intellect's new location just over a block to the east. I've updated the directions on our website, http://boulderruby.org, so please refer to it for more information. We haven't scheduled any presentations yet. Several of you have offered to speak on a topic for one of our upcoming meetings. Please let us know if you'll be ready for the July meeting. We also have plenty of openings in the coming meetings so if you have some ideas, let us know. I will be updating the website with details as they're available.

Oh, and useful too, but mostly hysterical. :) FYI, another interesting captcha system out there is ReCaptcha: http://recaptcha.net/ It uses captcha responses to help correct OCR errors in scanned books. Nice cause. I think there's some Rails plugins for it already, but it's also dirt simple to integrate with from scratch. I made a Movable Type plugin for it rather fast, and that included learning the (mostly undocumented) MT plugin API *and* remembering first-hand all the reasons I hate Perl. -Josh On Jul 2, 2007, at 7:12 PM, ara.t.howard wrote: > > NAME > > flatulent : CAPTCHA for FIGLET. > > SYNOPSIS > > the flatulent gem provides brain dead simple ascii art captcha for > ruby. > > URI > > http://codeforpeople.com/lib/ruby > http://rubyforge.org/projects/codeforpeople > > INSTALL > > gem install flatulent > > EXAMPLE > > def index > if params.has_key?

But Peter Booth did post a great link to Amy Hoy's blog, and the issue is something I'd like to address in the Ruby community. I'd like to get some thoughts and feedback from our little group before venturing out to the Ruby community at large. Step #1 for fixing the problem: "Creating Resources" What resources do we have in the Ruby community? * http://ruby-lang.org * http://ruby-doc.org * http://rubygarden.org (can't connect to it right now) * http://blade.nagaokaut.ac.jp/ruby/ruby-talk/index.shtml (Et al.) * http://www.rubyinside.com * and I'm sure there are many others that I don't know about What resources do we need in the Ruby community? * FAQ -- data mine the ruby-talk mailing list for the frequently asked questions, condense them down into a good, searchable FAQ page with coherent and authoritative answers. * Ruby specific search engine (Rollyo?) Any other resources that would be good to have? How do we go about creating these resources? Here are the two questions I'd like to talk about. 1) What Ruby resources would you point a "help vampire" to? (and don't just say Google) 2) What resource would you create to help someone learn Ruby -- i.e. the ultimate Ruby answer machine? For a start, it would be great to throw together a little page on the BDRG website that provides a "rules of the road" for asking questions and providing answers on the ruby-talk mailing list. Any thoughts on this one? That's it! I'd bring this up at tomorrow's meeting, but I'm heading off for a fishing trip. Thought I'd get everyone's little grey cells working on some creative solutions, in the mean time.

I was curious where the bottlenecks were. Builder obviously makes extensive use of method_missing, but after testing out method_missing I decided it wasn't that slow: 10 million normal method calls: 3.620000 0.000000 3.620000 ( 3.656555) 10 million method_missing calls: 4.190000 0.010000 4.200000 ( 4.193837) Other than that, Builder just does a lot of tag construction and is constantly appending to an output buffer. I didn't really see a better way to do this short of a native extension, so I decided to check out libxml-ruby's XML construction and try to write something Builder-compatible which uses it. I put together a simple proof-of-concept to see whether using libxml-ruby could improve the performance: http://pastie.caboo.se/79575 Not the most elegant thing in the world, but the benchmarks speak for themselves. Here's 3 runs of each, both from a fresh irb: libxml-ruby based proof-of-concept: >> puts Benchmark.measure { xml = XmlBase.new; xml.foo(:a => :b) { 100.times{ xml.bar(:c => :d) { 1000.times { xml.baz("Text goes here") } } } }.to_s } 3.130000 1.290000 4.420000 ( 4.433537) 2.850000 1.280000 4.130000 ( 4.133377) 2.810000 1.250000 4.060000 ( 4.070264) Builder: >> puts Benchmark.measure { xml = Builder::XmlMarkup.new; xml.foo(:a => :b) { 100.times { xml.bar(:c => :d) { 1000.times { xml.baz("Text goes here") } } } } } 9.300000 0.030000 9.330000 ( 9.374801) 9.290000 0.020000 9.310000 ( 9.315121) 9.280000 0.020000 9.300000 ( 9.316049) Using libxml-ruby is over twice as fast while still preserving API compatibility. It looks like Builder's slowdown comes from the actual tag construction/string appending being done in Ruby. -- Tony Arcieri ClickCaster, Inc. tony at clickcaster.com 720-227-0129 ext. 202 -------------- next part -------------- An HTML attachment was scrubbed...

SAMPLE # # app/controllers/sample_controller.rb # def c @var = 42 @c = widget 'c' render :layout => 'application', :inline => <<-rhtml var: <%= @var %>

<%= @c %> rhtml end # # lib/widgets/c.rb # Widget 'c' do attribute 'var' => 'forty-two' def answer 42.0 end end # # app/views/widgets/c.rhtml # controller var : <%= @var %>
widget var : <%= var %>
widget method : <%= widget.answer %>
