Why I Maintain This Blog

---

With ten years’ working experience, now you question me to detect whether a graph has a loop? As an infra engineer, I have never used a graph algorithm at work. It might be useful for some roles, but just irrelevant to me.

Lots of debates for this stupid code test. And yes, I hate it. But why I hate it so much? After thinking deeper, I realize part of my resistance is fear of rejections.

I admit I’m not so smart or clever. Most of the time I’m just diligent. And I had bad experience when I took ACM programming contest at college. Maybe I shall say, frustrating.

But it is what it is!

So why not stand up and conquer it? Maybe I can collect some interesting code puzzles? Help people to be more ready for the future coding interviews. Especially emotionally ready, I mean.

(Leave me comments! Help me to help others.)
