A rails model for gollum-lib, which is used to embed `gollum` into existing rails project. The `unindexable` and `unreadable` statuses are introduced. The `pull` and `push` method is added to have the git repository sync with its **remote origin**.
class Post
@data = Gollum::Wiki.new('doc/blog.git', :mathjax => true)
@@unindexable = 'page'
@@unreadable = 'pending'
def self.data
@data
end
def self.reload

A temp translation for my friend

An introduction to the physics of the loudspeaker

  1. a few concepts about the sound Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. People hear the sound when it reaches their ears. Without the media to propagate the waves, there would be no sound.

  2. Three physical quantities of the waves.

    1. Amplitude(A): The amplitude of the wave

  3. Frequency(F): The number of oscillations per unit time (the frequency range that human can hear is 20-200000Hz)
