Course Introduction：Keylogger is a tool that records keyboard input and may be used to legally monitor or maliciously steal sensitive information. It is divided into three categories: software type, hardware type and kernel type. It can be detected through abnormal behavior checking, task manager viewing suspicious processes, scanning with anti-virus software, and checking external devices. Preventive measures include installing reliable antivirus software, not clicking unknown links at will, using a virtual keyboard to enter sensitive information, changing passwords regularly, and enhancing protection with system-level protection features such as "kernel isolation" of WindowsDefender.

Course Introduction：The key to changing the keyboard layout on Windows is to find the correct setting position. The steps are as follows: 1. Add a new layout: Go to "Settings" → "Language and Region" → Select the current language → "Keyboard" → "Add Keyboard" and select the desired layout from the list; 2. Switch the layout: Switch through the taskbar language icon or Win space shortcut key; 3. Change the default order: Drag in "Language and Region" to adjust the priority of keyboard layout; 4. Solve the problem of not finding the settings: Try to search for "Region and Language Settings" or use the control panel. Note that the American keyboard that comes with the Chinese input method needs to be confirmed whether it is the required layout, and some operations may require administrator permission.

Course Introduction：Binance, Ouyi and Huobi are the three mainstream virtual currency trading platforms, and the choice needs to be weighed based on personal needs. 1. Binance is suitable for users who pursue diversified products. It has many currencies and fast updates. It supports multiple trading methods, but the interface is relatively complex; 2. Ouyi is suitable for advanced users, with rich derivative tools and provides quantitative API interfaces. It is recommended that novices start with small or simulated transactions; 3. As an old platform, Huobi has simple operation and high project quality, but is gradually withdrawing from the Chinese market due to supervision. When choosing a platform, you should consider factors such as currency needs, transaction type, language customer service, and safety compliance. There are no absolute advantages and disadvantages. The key is to match your own habits and needs.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
