Prerequisite: Getting the Code

略

Part 1: Using command-line arguments

main函数开头需要加上下面的代码设置下日志的输出方式

logging::LoggingSettings settings;
settings.logging_dest = logging::LOG_TO_ALL;  // 默认就是控制台
settings.log_file_path = FILE_PATH_LITERAL("hello_world.log");
logging::InitLogging(settings);

Part 2: Callbacks and Bind

是个move-only对象

// The type of a callback that:
//  - Can run only once.
//  - Is move-only and non-copyable.
//  - Takes no arguments and does not return anything.
// base::OnceClosure is an alias of this type.
base::OnceCallback<void()>

执行的时候要加std::move

void MyFunction1(base::OnceCallback<int(std::string, double)> my_callback) {
  // OnceCallback
  int result1 = std::move(my_callback).Run("my string 1", 1.0);

  // After running a OnceCallback, it's consumed and nulled out.
  DCHECK(!my_callback);
  ...
}

Part 3: Threads and task runners

Threading and Tasks in Chrome

There are a number of ways to post tasks to a thread pool or task runner.

• PostTask()
• PostDelayedTask() if you want to add a delay.
• PostTaskAndReply() lets you post a task which will post a task back to your current thread when its done.
• PostTaskAndReplyWithResult() to automatically pass the return value of the first call as argument to the second call.

bottom-up-attention代码地址
尝试过直接在conda配置环境，然后代码年代久远，最后还是使用docker才配置成功

docker配置

docker镜像 docker pull bvlc/caffe

Makefile修改 参考https://www.codeleading.com/article/61395175040/
注：LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial不用添加

报错ImportError: cannot import name '_validate_lengths
运行pip install --upgrade scikit-image

报错ImportError: No module named _tkinter, please install the python-tk package
运行apt-get install the python-tk package

class String {
public:
  // ctor
  String(const char *cstr = 0);
  // copy ctor
  String(const String &str);
  // copy op=
  String &operator=(const String &str);
  ~String();
};

Big Three

1. 编译器默认的copy ctor和copy op=都是bit by bit拷贝，类中含有指针时会有内存泄露
2. 为什么copy op=返回引用
   • 非必须，为了链式赋值使用，参考stackoverflow.com
3. 注意函数参数和返回值

int main() {
    vector<int> a(0);
    for (int i = 0; i < a.size() - 1; i++)
        cout << a.size() - 1 << endl;
}

a.size()返回一个无符号整型，当a的大小是0时，a.size() - 1返回一个正数，导致访问越界。
