I would like to use two things to describe the importance of exploring the value of life. ...

AI Is Not AI

OpenAI ChatGPT Reference DeepMind Reference InstructGPT Reference The most talked about topic I’ve seen on Twitter lately is ChatGPT, and many people are raving about it. For a creator to use AI in their creative process to quickly prototype their work is certainly a great thing in the business world. chatGPT can add inspiration to screenwriters, give problem solvers ideas, and give translators help with more accurate language translations. So does ChatGPT count as AI in the true sense of the word, i.e. does it pass the Turing test. Although we don’t know the answer, we can be sure that ChatGPT must have collected huge amount of Internet data for model training, and the parameters of the final model are amazingly huge. ...

Moosefs Master High Availability

I designed a rudimentary k8s persistentvolumeclaims solution myself, using Moosefs on the backend as a distributed data store. The principle is based on the kubernetes events mechanism, when a create pvc message is received, the backend control application will create the corresponding pv on moosefs and bind the corresponding pvc, in order to facilitate the application to move between nodes, I mount the moosefs file system to each worker node, here a problem arises: how to keep the moosefs master high availability! ...
