Motivation : In an object-oriented system, some objects are subject to some reasons (for example, the overhead of object creation is large, some operations require security control, or external access is required ), direct access may cause a lot of trouble to the user or system structure. How can we manage/control the unique complexity of these objects without losing transparent operation objects? Adding an indirect layer is a common solution in software development.

Motivation : ThinkPad has multiple models, such as T43 and t60. Each model supports multiple working modes. Each model has different implementations in different modes. With the continuous development, there are more and more models and working models. How to separate ThinkPad from the changes in model and working mode so that they change independently, without introducing additional complexity (the complex

1. Find other nearby wireless networks, which means we need to configure a security mechanism for our home router. For example, you can modify the login username and password, and encrypt WAP files to prevent other users from obtaining and using resources.
2. log on to the "192.168.0.1" interface for a long time. In 3-5 minutes, the wireless network connection experiences a signal decline. The signal drops to 11 Mbps, and the connection is exited

Lenovo fingerprint management software has a major vulnerability. Please update and correct it!
Although urgent corrections have been made up, it is hard to imagine Lenovo's Fingerprint identification software Fingerprint Manager Pro, which is used in many laptop and desktop products 」, previously, only a low-encryption algorithm and a set of hardcoded passwords were used. As a result, people who are interested can easily skip Fingerprint Authentication and directly access the computer system
