  The First Bite on etcd Code

Etcd, one of the crucial components of Kubernetes. If APIServer is the heart, then etcd is the blood vessel that sends the end state of Kubernetes resources to various “organs”, providing high-speed, stable storage, and supporting APIServer’s high load performance. What if the etcd is not working properly? Just the condition as someone has a vascular disease. The deeper you know about them, the better diagnose you can make when issues occur. from unspl...

  Google’s BERT - What changed and what didn’t

Most of us should already be aware that Google has updated their algorithm. The new algorithm is called BERT (Bidirectional Encoder Representations from Transformers) and has made at least a couple of modern-day SEO experts scratching their heads trying to figure out what it means.   The good news is that there have been no major changes enough to make SEO experts change their strategies drastically. This means that all of the linking and keyword researching techniques remain the same and w...

A Chinese developer—myself—took notice of all this. After days of probing and searching, I identified...
