In Go, we use go to create a new goroutine. A goroutine is a lightweight thread managed by the Go runtime. We are all familiar with the states of operating system threads. In The time in computers: how long will it take to switch the context?, we summarized the states

sync.WaitGroup, I believe all gophers have used it. It is a concurrency primitive in the package sync used for task coordination. It solves the problem of concurrency waiting: when a goroutine A is waiting at a checkpoint for a group of goroutines to complete. Without this synchronization primitive, how

Cache Consistency Issues In concurrent programming, it's common to encounter issues like this. For instance, concurrency issues arise when two goroutines simultaneously read and write to a variable.

In existing logging libraries, including the slog logging library introduced in go 1.21.0, typically support log file rotation and segmentation. However, these functionalities are not built-in directly but require manual configuration to enable. This article was first published in the Medium MPP plan. If you are a

unsafe.Pointer In the previous article, we compared the differences between three types of pointers in Go. You can check that out before diving into this one. Now, let's summarize the distinctions between the three pointer types. * Ordinary pointers: They do not support pointer arithmetic, retain both address

网页设计和开发是一个不断进化的领域，设计师和前端开发者们经常面临一个共同的挑战：如何快速、高效地将概念化的设计草图转化为实际可用的 HTML 代码。这一过程不仅耗时而且容易出错，尤其是在将复杂的设计想法具体实现时。在初步设计阶段，往往需要频繁地修改和调整，如果每一次修改都需要手动编写代码，无疑会大大拖慢项目的进度，增加项目成本。 This article is first published in the medium MPP plan. If you are a medium user, please follow me in medium. Thank you very much. 目前我们我们有两种办法解决这个问题，第一种是低代码模式，第二种是使用AI。我个人认为，Ai将会合并低代码模式，目前已经有很多商业公司在做这件事情了，今天的主角是一个在GitHub上有一个超过13k star 的项目draw-a-ui
