Things I like#

I enjoy programming. I am most familiar with Python and fairly proficient in using Numpy, Matplotlib and others. I use Pandoc to generate beautiful document from my daily notes.

My favorite editor is Neovim. I have been using Neovim for everything related to text editing, e.g., from writing Python to editing my notes, for over three years. My Neovim config is here. I frequently write posts about Nvim. A list of nvim-related posts I have written can be found here.

I am a big advocator for Stack Overflow. Thanks to all these wonderful guys on Stack Overflow, I really learned a lot. You can find me on Stack Overflow most of the time.

I enjoy reading fictions, non-fictions (science, biography, history) etc. One of my long-time favorite is Note of Hiding in the East by Pu Zong, which depicts the lives of academics of China’s top university during the WWII, in the remote south western province Yunnan.

I enjoy listening to songs by Cheer Chen and Deserts Chang.

I like to learn new things and I enjoy playing with digital devices (smart phones, Kindle, iPad, etc.).

FAQ#

Q1: Why do you have those annoying ads on your blog?
A1: Because hosting the images on this site costs money monthly. I need to make ends meet by using ads. If you do not like ads, you can use ad blocker to block those ads.

Q2: Why do you write your blogs?
A2: The reason is two-fold. First and foremost, most of my knowledge here come from the free resource shared by numerous other people. Sharing my knowledge here can act as a contribution to the Internet and help other people. Second, my blog servers as a public note so that when I want to check specific detail about a subject, I can find it easily via search engine.

Q3: Are you interested in optimizing your blog?
A3: No, I am not interested. I constantly get emails stating that my blog is ill-optimized for mobile devices or has design issues. To those people, I do not intend to do the so-called optimizations. Do not email me, and I will not respond to these kind of emails.
