. This is called the " expert trap ". Everyday, programmers are eager to become an expert in a team or company, but when that day comes, we are already in the trap. The deeper we drill in the existing code, the deeper we ourselves are. The existing code is so stable (so big and so good) that we gradually lose the ability to write a complete project from scratch independently. What's worse, if our main job is to maintain these existing code and seldom develop new features, it won't take long, no

The schedule method is used to delay the specified time to perform a specified task. If you need to perform recurring tasks periodically, you can use either the Scheduleatfixedrate or the Schedulewithfixeddelay method, which is different in that the former is performed at a fixed frequency and the latter at a relatively fixed frequency.
Scheduleatfixedrate and Schedulewithfixeddelay do not cause the same task to be executed concurrently, regardless of whether the task'

Software as a service (SAAS)ModeAs early as 1990, the concept of software as a service had emerged. SAAS (software as a service) and "On-Demand software" (On-Demand software), The Application Service Provider (Asp, Application Service Provider), and hosted software (managed software) it has a similar meaning and is a mode of providing software through the Internet.

work is just to maintain the existingCode with little feature development, after a while, no matter how much code we 've read and studies, we will find we cannot write code execution-generated even if the problem is as simple as a graduate school assignment. this is the programmer's dilemma:We make ourLiving by coding, but the big companies who fed us tend to destroy our ability to make a living.
How to get away from this dilemma?
