I have a Raspberry Pi 2B+ that has been collecting dust for quite a while. Due to frequent power outages at school, I haven’t used it for running scripts or downloads. However, recently, the SSH connection to the VPS has been dropping due to power/network issues, which has been quite frustrating. So I’ve decided to turn the Raspberry Pi into a portable compiling environment.

When a class we write does not explicitly provide a constructor but the compiler needs a constructor (be sure to note this phrase), the compiler will generate one for us. However, the default constructor generated by the compiler does not meet our expectations of what it can accomplish.

The methods for achieving inter-process/thread communication include:

1. Inter-process communication methods: file mapping, shared memory, anonymous pipes, named pipes, message slots, clipboard, dynamic data exchange, object linking and embedding, dynamic link libraries, remote procedure calls, etc.
2. Thread synchronization methods: events, critical sections, mutexes, semaphores.

From C language to C++03, the OO features feel absolutely great. Recently, I focused on the new features of C++11 and found many fantastic syntactic sugars! It’s also very enjoyable to use.

When we delete a pointer, the object it points to will be deleted. However, this does not happen when pointer objects are stored in an STL container.

Using profiler to analyze the performance of code is more efficient, detailed, and intuitive than pure cognitive analysis.

In C++, when the operand types of an operator are inconsistent, these operands will be converted to the same type. Type conversion is divided into implicit conversion and explicit conversion.

When designing classes to overload operators, it is essential to choose whether to implement the operator as a member or as a regular non-member function.
