于是我就研究了一下随机类RNG,最终找到了问题的原因。...注意到程序中有如下一行代码 RNG rng(12345); //随机数产生器 OpenCV里RNG类构造函数初始化为固定的值后随机种子也是固定的,所以在相同的平台环境下,编译后每次运行它,显示的随机数是一样的...i) { cout << rng.uniform(1, 1000) << endl; } } 构造函数rng初始化为12345,程序运行后,每次生成的“随机数”都一样,如下图1: ?...图1:rng(12345)结果 更改构造函数rng初始化为1234,每次运行生成的“随机数”仍然都一样,如下图2: ?...图2:rng(1234)结果 继续更改构造函数rng初始化为123,每次运行生成的“随机数”仍然都一样,如下图3: ?
在聊Kafka高可靠之前,先在评论区来波RNG NB好不好! 什么叫可靠性? 大家都知道,系统架构有三高:「高性能、高并发和高可用」,三者的重要性不言而喻。
