For so many years that I have programmed in C, C++, java, C#, php, python. And got stucked, googled, and discovered so many weird tricks, or something people would easily forgot and end up spending a lot of debugging. It's time to start recording them.

During my work/study, I have lots of thoughts and notes that I'd like to put together and share to help others who may not know. A major portion of the knowledge from this blog were from the classes I am taking or took, and the work I have done or the book I have read.

I am/will, to my best knowledge, to make the blog and any post to be clear and I am happy to receive any request for clarifications. And I promise to not intentionally write anything to mislead my audiences in any political, academic direction.
