Realize dynamic expansion and contraction of job tasks based on KEDA
Background With the widespread use of Kubernetes, there are demands for dynamic expansion and contraction of Kubernetes in many scenarios, such as dynamic expansion and contraction at the Pod level and dynamic expansion and contraction at the Node level. The realization of these scenarios is crucial to business flexibility. How to make good use of […]

Write your first smart contract in Remix
To put it simply, a smart contract is:A contract or a set of instructions deployed on a decentralized blockchain. When this contract or this set of instructions is deployed, it cannot be changed and will be executed automatically. Everyone can see the termsin the contract. The deeper understanding is that these codes will be executed […]
WEB3 creates a React front-end Dapp environment and integrates the solidity project, integrating the project structure to facilitate the front-end to get the contract Abi
Okay, everyone, after what we have said above, WEB3 solidity takes you to write test code to operate orders, create/cancel/fill operations, we wrote a script to test the order business. Unexpectedly, it ran quite well. So starting today, we can start operating an operation of our front-end Dapp. In the whole process, there is indeed […]

Design analysis and shortcomings of contract upgrade standard ERC2535
Design analysis and shortcomings of contract upgrade standard ERC2535 Safful recently audited an implementation of the Diamond Standard, a new upgradable contract model. Writing standards is a laudable undertaking, but there are many concerns about the Diamond Standards and their implementation. This code is the product of over-engineering and comes with a lot of unnecessary […]
33. HPA realizes automatic expansion and contraction
Achieving dynamic expansion and contraction of business applications through HPA HPA controller introduction When system resources are too high, we can use the following commands to implement the Pod expansion and contraction function $ kubectl -n luffy scale deployment myblog –replicas=2 But the process is manual. In actual projects, what we need to achieve is […]
