On 17-May-2008 there was 26th Ruby Kansai Workshop in Kyoto . A lot of fun like always 
The chatlog from the presentations is available on lingr.
I gave a presentation “Ruby off Rails” about developing web applications in Ruby, but without Rails – Sequel, Rack, Ramaze etc. talk. The presentation slides:
The sources from the talk (plus some extras – rack middleware examples) are available on Google sites for download.
There was no time to speek about Tamanegi – my feeds aggregator in Ramaze , but maybe on some other meeting…
There are also another two presentations:
“5 ways to run Ruby on Rails web applications”
by okkez-san
Benchmarking CGI, FastCGI, mod_ruby, mod_rails and mongrel_cluster. Received very good documentation with configs for all mentioned deployment options.
Okkez-san is using Rabbit – very cool presentation tool, written in Ruby! Just needed ruby-gnome. Will try it soon maybe.
Some notes:
- ebb is still a pain to install
- mod_ruby is not bad deployment option
- webrick overperforms fastcgi for simple installs (still a valuable option for intranet for example)
- thin is fast
I think thin is faster because of the underlaying EventMachine TCP stack implementation in C. The others are just pure Ruby-based, so there is nothing to compare for simple requests (ab benchmarks).
“Agile web posting with Ruby”
by ujihisa-san
There are sooooo many web services around. Can the posting to them be automated, using Ruby-based tools?
!!! Big Fat Warning: The presented tools will make you very ‘productive’. Maybe your friends will stop following you. Use on your own risk! 
Main working horse – www:mechanize ruby port :
gem install mechanize
So far so good. But can you post directly from VIM? Seems there is vimscript – i way to customize vim in different languages. Try:
vim --version
and if you see +ruby you can use ruby in vimscripts like:
# ~/.vim/plugins/some_plugin.vim ... VIM.evaluate(’..’) evaluate %[sdfsds] ...
And even better: there are already a lot of ready ruby-based VIM plugins in the CodeRepos vim repository
20th “Ruby for beginners” lesson
With a ‘little’ help from google my answers was:
(‘Aho’,’Bow’ and also say ‘Aho’ for numbers that contain ‘3’):
puts (1..100).map { |i| (s=(i%3==0?'Aho':'')+(i%5==0?'Bow':'')+(i.to_s =~ /3/?'Aho':''))==""?i:s }
I like Jeremy Voorhis’ implementation . Just modified it to handle 1 bottle situation:
#!/usr/bin/env ruby
def expensive
@expensive ||=
begin
n = 99
buf = ""
begin
buf << "#{n} bottle#{n>1?'s':''} of beer on the wall\n"
n -= 1
end while n > 0
buf << "no more bottles of beer"
end
end
puts expensive
