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

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.

After I switch my blog to Octopress, I realize that compare with the Google App Engine, the Github gh-pages hosting service is much slower (10 times compare with GAE ping value, 6xxms vs 6xms)

So I believe it's better to hosting the static blog file to GAE, switch to GAE also enable server side script as a bonus if you didn't care about portable, which is the most reason I using Octopress.

There is tons of good installation guide for Rails, but I still think it's reasonable to log my installation here as I will change it time to time to make this blog ever better.

Just very glad to annource that I just finishing switch my blog from Micolog to Octopress.

Micolog is a Google App Engine based blog, when I decide to use at Auguest 2011, the GAE price model is not so tough and Micolog is quite good for personal tech blog choose.

But after GAE price policy changed, I meet quite a lot Datastore Reads quota over Free budget, which lead almost the original blog inaccsible 3~4 hours everyday.

At same time, in the passed year, my favor language also change from Python to Ruby, so to rebuild the blog using a Ruby language solution, the Octopress is more good choose for me.

The most unique feature of Octopress is it have no bandend DB require, all the blog content is purely static html file, which will be generate before deploy based on your markdown blog file. That make Octopress requirement very very minimal compare with Wordpress/Micolog. Basicly a static page site is already enough, so it make possible to just deploy this blog on Github directly.

Hoping for a long time, I'm not worry about the blog facility anymore.
