井底之蛙

I just installed Hiweed, an Ubuntu based distributed edition on my ThinkPad T43 yesterday. Unfortunately, track point can not scroll with the blue middle button. But fortunately, there is a solution. According to this guide, add the following lines in "/etc/X11/xorg.conf" and comment the original. After reboot, scrolling works.

Section "InputDevice"
      Identifier "Configured Mouse"
      Driver "mouse"
      Option "CorePointer"
      Option "Device" "/dev/input/mice"
      Option "Protocol" "ExplorerPS/2"
      Option "Emulate3Buttons" "on"
      Option "Emulate3TimeOut" "50"
      Option "EmulateWheel" "on"
      Option "EmulateWheelTimeOut" "200"
      Option "EmulateWheelButton" "2"
      Option "YAxisMapping" "4 5"
      Option "XAxisMapping" "6 7"
      Option "ZAxisMapping" "4 5"

Playing with scRUBYt! is not very easy. When I try to run the following example it complained there is no ‘openssl’ lib could found.

require ‘rubygems’
require ’scrubyt’

google_data = Scrubyt::Extractor.define do
  fetch ‘http://www.google.com/’
  fill_textfield ‘q’, ‘ruby’
  submit
      
  result ‘Ruby Programming Language’
end

google_data.to_xml.write($stdout, 1)
Scrubyt::ResultDumper.print_statistics(google_data)

I googled and found maybe need ‘libopenssl-ruby1.8‘. After ‘apt-get install libopenssl-ruby1.8′, it still complained no ‘openssl’ cound found.

In the end, I found a solution here. Because I installed Ruby from compiling source, I should compile to install ‘openssl’ lib also.

Enter your ruby-source/ext/openssl directory and then

ruby extconf.rb
make
make install

Well, now the scRUBYt! example could run without any complains. Good.
