I'm trying devise_ldap_authenticatable during 2013 CNY, after spending a lot of time, found below script is quite usful if you want to using LDAP authenticate but found something wrong and start trying to debug.

10 months ago, I start my Ruby & Rails life, installation method at that time is greatly improve after that time, the Rails Installer also seems stop maintain since then. So here is another more professional way to install Ruby & Rails in Windows:

R package Shiny originally not support R Studio Server, so shiny.R need change before install

cd ~
wget http://cran.r-project.org/src/contrib/shiny_0.13.2.tar.gz
tar xvfz shiny_0.13.2.tar.gz
vi shiny/R/server.R
# search 'Listening on http://' and replace 'startServer(host, port' to 'startServer("0.0.0.0", port'
# search 'Test port to see if we can use it' and replace 'try(startServer(host, port' to 'try(startServer("0.0.0.0", port'
# search 'QtWebKit' and replace 'paste("http://", browseHost,' to 'paste("http://", "your.rstudio.host.name",'
tar cvfz shiny_0.13.2-server.tar.gz shiny
R CMD INSTALL shiny_0.13.2-server.tar.gz # (may need install htmltools before this line)
service rstudio-server restart # if you previous install shiny from CRAN

Before install shiny server, make sure you install node.js version 0.8.17 or higher and meet prerequisites.

npm install -g shiny-server # install shiny-server

or use the offline install mode:

git clone https://github.com/rstudio/shiny-server
cd shiny-server/
node tools/bundle-offline-installer.js
mv shiny-server-0.3.0.tgz ..
cd ..
npm install --no-registry -g shiny-server-0.3.0.tgz

The sample shiny server config file.

run_as shiny;
log_dir /var/log/shiny-server/;
server {
  listen 3838 127.0.0.1;
 
  location /first {
    app_dir /var/shiny-server/first;
  }
 
  location /diamonds {
    app_dir /var/shiny-server/diamonds;
  }
}

Now I'm using the Rubymine instead of pry-debugger as my primary Rails environment, Rubymine has much great debug facility and what's more, I spend $17 when the JetBrains offer 75% off at the Mayan Doomsday.

But I found a problem that rubymine always refuse to enter the debug mode when I using my pl-form project in below warning:

debugger-1.2.3/lib/ruby_debug.so: warning: already initialized constant VERSION

finally I found prject Gemfile need a little review:

group :development do
  gem 'quiet_assets'
  # Disable below two line if you using rubymine
  #gem 'pry-rails'
  #gem 'pry-debugger'
end

Inspired by Nathan Yau's tutorials - How to Make Bubble Charts, fetch the data directly from Oracle.

Install R in Ubuntu is extremely easy if you don't meet any exception, but if you meet, then you'd better be a very advanced linux user :-)

Very thanks to TopGeek and Capital of Statistics given this R lecture, as part of Seven Languages in Seven Weeks, the R language is more unique than the original Pragmatic book language Prolog.

The answer for Python Code Dojo Class Two, which I attend today as seven language in seven week hold by Shanghai TopGeek.
