The basic setup I am trying to accomplish is using pdftk with PHP on IIS
I am trying to setup pdftk to run with PHP for processing on our internal server. I have tested that pdftk does work through command on the server but I cannot get it to run through <em>php</em>. I have tried changing from <em>exec</em>() to passthru(), system(), and shell_<em>exec</em>() just to be sure it wasn't specific.
The main solution I'm finding is saying that the IUSR account needs at least read & <em>exec</em>ute privileges on <em>cmd</em>.exe in the system32 folder. I have tried this and it did not change anything. I always get either "Unable to fork" or "Unable to <em>exec</em>ute" depending on which command I'm using.
在Windows平台下安装PHP后，在使用PHP的<em>exec</em>、shell_<em>exec</em>等函数时，经常会遇到报错：unable to fork...，这实际上是因为PHP对<em>cmd</em>.exe没有足够的权限引起的。
解决方法：为C:\Windows\System32\<em>cmd</em>.exe（系统不是安装在C盘请相应更改）添加IUSR_ComputerName （ComputerName是你的计算机名称）用户的读取、运
I have the following line in a <em>php</em> file called batchrender.<em>php</em>:
<em>exec</em>('/Applications/Adobe\ After\ Effects\ CC\ 2014/aerender -project /Users/abc/Sites/AETEST1.aep -comp "Komp1" -output /Users/abc/Sites/xyz.mov');
When I call this file via web browser it should render a movie with the aerender unix command.
The output is
PROGRESS: ...After Effects successfully launched...
but that's all and it stops <em>exec</em>uting without any error. No movie is rendered. (No counting frames are displayed)
When I <em>exec</em>ute the exact same <em>php</em> file from the command line interface (Terminal) like:
$ <em>php</em> batchrender.<em>php</em>
All works perfect and it starts to render the movie.
in the httpd file the user for apache2 is defined as "abc" and group is "staff" the terminal is also started with user "abc"

《Neural Networks and Deep Learning》读书笔记第四篇本章其实和前面章节的关联性不大，所以大可将本章作为小短文来阅读，当然基本的深度学习基础还是要有的。主要介绍了神经⽹络拥有的⼀种普遍性，比如说不管目标函数是怎样的，神经网络总是能够对任何可能的输入，其值（或者说近似值）是网络的输出，哪怕是多输入和多输出也是如此，我们大可<em>直接</em>得出一个结论：不论我们想要计算什么样的函数，...
之前的系列文章从 CPU 和内存方面简单介绍了一下汇编语言，但是还没有系统的了解一下汇编语言，汇编语言作为第二代计算机语言，会用一些容易理解和记忆的字母，单词来代替一个特定的指令，作为高级编程语言的基础，有必要系统的了解一下汇编语言，那么本篇文章希望大家跟我一起来了解一下汇编语言。

整理了一下内部类的相关知识，算是比较全，比较基础的，希望大家一起学习进步。
一、什么是内部类？
在Java中，可以将一个类的定义放在另外一个类的定义内部，这就是内部类。内部类本身就是类的一个属性，与其他属性 定义方式一致。
一个内部类的例子：
public class Outer {
private int radius = 1;
public static int co...
