In dash of Unity, there’s no obvious way to add a new application shortcut in it. Here the solution(from here).

After I installed Ubuntu 12.04, Unity shows me many unsatisfied flaws. One of them is: when the computer starts and the login screen is been displayed, the monitor complains “resolution out of range”.

When using octopress, if I want to preview an unpublished item(indicated in the yaml front matter), I have to manually modify the line from “published: false” to “published: true” first, then preview it. What I want is to automatize it.

Here is my study note of RuanYiFeng’s “Internet Protocol Suite Part I“ blog.

I want to do this because my high school class has a lot of messages there(over 4k items during the last 10 years). Here is the brief introduction about how I did this.

Rake is a build tool written in Ruby. You can compare it to make in the C world and ant in the Java world. However, it has something over them.

In this code snippet, I use “nokogiri” to get/parse HTML content and convert the blog content into octopress-style markdown files.

I wrote this Ruby code snippet to process some image files. This is a good example how easy it is in Ruby to call command line utility.
