Anti-virus attack and defense article 012nd: using inline hook for active defense

一、前言         之前文章中所讨论的恶意程序的应对方法,都是十分被动的,即只有当恶意程序被执行后,才考虑补救措施。这样,我们就会一直处于后手状态,而如果说病毒的危害性极大,那么即便我们完美地修复了诸如注册表项,服务项等敏感位置,并且删除了病毒本身,但是它依旧可能已经破坏了系统中非常重要的文件,造成了不可逆的损伤。因此这篇文章就来简单讨论一下利用Inline HOOK技术实现主动防御,在病毒执行前,就主动将危险函数劫持,如同一道防火墙,保护我们计算机的安全。   二、Inline

Calculation and source of Matrix Multiplication

矩阵乘法的计算 矩阵,是线性代数中的基本概念之一。一个m×n的矩阵就是m×n个数排成m行n列的一个数阵。 矩阵乘法是一种高效的算法可以把一些一维递推优化到log(n),还可以求路径方案等,所以更是一种应用性极强的算法。必须注意的是,只有当矩阵A的列数与矩阵B的行数相等时A×B才有意义。 一般单说矩阵乘积时,指的便是一般矩阵乘积。若A为m×n矩阵,B为n×p矩阵,则他们的乘积AB(有时记做A·B)会是一个m×p矩阵。其乘积矩阵的元素如下面式子得出: 上面是一个通过代数公式的方式说明这类乘法的抽象

Introduction to closures

  先扯一段和代码无关的话题。long long ago,我还是个英语很溜的孩子,当然现在也不是很差。学英语的时候,我几乎不听老师的语法讲解,但是我就是不会用错。写代码亦是如此,我不会关心代码为何要这么写,随心所欲。所以我不会去关注闭包实现的原理,只会关心它的用处。so 不要问我闭包为什么这么写,我也不会告诉你什么是闭包。   闭包到底有什么用?先看一个很经典的例子。 1 2 3 4 5 0 6 1 7 2 8 3 9 1
