Chen Dong stood on the railing, Li Yu comforted him and said: "Physical infinite, life has Jing xianggong do not have to be too sad ." Chen Dong shook his head and I was thinking about a dream. There is a place to drink in the dream. There are people singing and dancing there. He is drinking, and there is a woman next to him. She told him that you are a man. It is a good story to tell

The biggest enemy of software design is the constant change in demand. Sometimes there are endless changes, so the project development will delay the delivery date indefinitely During Repeated modifications and updates. Changes, such as the sword of damos hanging above the head, make many software engineering experts unable to do anything. Just as a silver bullet that cannot be used to solve software development, it seems impossible to completely eliminate changes in the cradle. Then, it is desi

Recently, Yelp's SRE engineer Dmitriy Samovskiy published an article titled "The Operation of the new Era", in which he briefly introduced changes in the focus and role of operations in the context of cloud computing.In fact, 6 years ago, Dmitriy wrote an article on the trend of DevOps, in which he argued that system administrators need to develop beyond simple scripts and focus on server stability and uptime. But over the past six years, with the dev

This is a creation in Article, where the information may have evolved or changed. Objective In the era of mobile Internet, new technologies need to support the environment, new software delivery process and it architecture, so as to realize the platform of architecture, delivery continuity and business service. Containers will become standard deliverables for next-generation applications, and the container cloud will help enterprise users build research and development processes and cloud platfo

goal is to provide for the next 2-4 years of technology development to pave, Lay the groundwork for the cloudnative transformation of applications and the DevOps practices of the entire technical team. Container cloud The first step is to achieve full lifecycle management of the application, enabling applications to go live, roll back, upgrade, expand/shrink, and offline. For historical reasons, some application configurations are coupled to the env

K8s Native provides a number of extension mechanisms that can be extended without intrusion, such as CRD, API aggregation, and so on. This share mainly introduces the exploration and practice of NetEase cloud container service platform in k8s extensibility, hoping to provide some ideas and inspiration for ev

. In fact, most organizations have virtualized their computing resources and may have migrated to commercialized hardware to implement firewalls or load balancers (basically, using a x86 box running Linux or BSD, with some special software superimposed). But their storage and network resources are still focused on the hardware, even if the commercial IP devices on it are behaving as much as possible in the way the hardware devices do, rather than the performance of similar software. The next ma

UNIX won in the enterprise because of its power, not because of its usage of use. microsoft won the desktop because of its rights of use, not because of its power. now, we're seeing a convergence of those two worlds where we need should of use and power at the same time, and I think that's the central challenge for J2EE and Java.

-based game for them. Is there any open-source project that is using your new knowledge? You will find that contributing modules or even creating projects is a good learning method for open-source communities. Sometimes it is easier to continue working from an existing project to the beginning. Is there any profit/non-profit organization that may use applications based on this new skill? In this case, you can learn and develop an application and obtain a user group to provide you with a large am

machine learning system on a browser. React:react provides an easy way to create complex management and data-intensive apps. It is also very fast because the virtual DOM is one of React's USP. It can be said that React Native has consolidated the status of React as the authoritative front-end Java library, making it easy to build cross-platform. Angular: It's a fully fledged framework, and it has more tool kits than React. And because it was created by Google, you can be confident that it alway
