    Take something with a pinch of salt: ‘姑且听着,不能尽信’. A second reason for the lack of panic is that people in Brussels take everything Johnson says with a pinch of salt. Johnson has previous form for sudden changes of heart, and no one is ruling out the possibility that, come the October 17 EU summit, he will request another Brexit extension if it suits him politically.

    Introduction A Hidden Markov Model (HMM) is a stochastic model that captures the statistical properties of observed real world data. A good HMM accurately models the real world source of the observed data and has the ability to simulate the source. Machine Learning techniques based on HMMs have been successfully applied to problems including speech recognition, optical character recognition, and as we will examine, problems in computational biology. The main computational biology problems with HMM-based solutions are protein family profiling, protein binding site recognition and the problem th

    microsoft Jonathan Caves给出的解释: (1)The reason for this limitation is related to the fact that most FP values can only be represented as an approximation and on some platforms generating this approximation is a non trivial operation and hence a static initialization of the variable would not be possible. (2)The problem is that on some platforms FP constants have to be generated dynamically (no - I can't name any such platform) and so the compiler can't use them as constants. Hence the C++ Standard disallows them. 也就是问题在于一些平台对于浮点数的动态处理

    1. 永远不要复制代码 不惜任何代价避免重复的代码。如果一个常用的代码片段出现在了程序中的几个不同地方,重构它,把它放到一个自己的函数里。重复的代码会导致你的同事在读你的代码时产生困惑。而重复的代码如果在一个地方修改,在另外一个地方忘记修改,就会产生到处是bug,它还会使你的代码体积变得臃肿。现代的编程语言提供了很好的方法来解决这些问题,例如,下面这个问题在以前很难解决,而如今使用lambdas却很好实现: ///<summa

    猫可以和国王看齐,自然引申为人人平等。 场景: James sees his student, a boy named Ricky, walking toward the faculty dining hall. James: Hey, Ricky. What are you up to? Ricky: Oh, hi, James. To tell the truth, I'm sweating a little. James: Why's that? Ricky: I've been invited to lunch with the school president. James: Cool! You should be honored. So, what's the problem? Ricky: Well, what if I screw up? Dump something on him, or put my foot in my mouth or something? James: Relax. The president's a cool guy, salt of the earth. Besides, "A cat may look at a king."
