Hi there

I’m Denny Zhang. A coder at work.



Why I maintain this blog?

I’m bad at memorizing things. Forget to do something on time? Poorly prepared?

These usually result in uncomfortable experience!

Why not collect the best practices? Then present them as cheatsheets for different scenarios. Should be a good idea, right?

Each cheatsheet will come as a dedicated blog post. And everything is also available in GitHub:

Hope you find the website useful?

If not, please talk to me.

Let’s make it better. More people could benefit from our effort.
