写程序的程序？

例如，如果程序设计人员拥有一个希望调用的用cobol写的现有应用程序，那么他们可以用EGL很容易地开发代码，并且让egl生成调用此应用程序的服务。
For example, if programmers have an existing application in COBOL that they want to call, they can develop the code easily in EGL and have EGL generate the service to call this application.
说点题外话，我承认这是一个完全无用的程序，跟我们之前写的两个程序一样,我们为什么需要写个程序来解决这个数学运算呢？
Now as an aside, I'll admit this is a completely useless program, much like the first couple of ones we did because why would you write a program just to solve this?
真正的学习应用程序拥有一套评判标准来确定它们是为了教育的目的。所以父母们与其写说所有的这些应用程序、游戏都是浪费时间，不如真正有心想想他们的孩子想要探索什么。
Real learning apps have a set of criteria that qualifies them as educational, so rather than writing them all off as a waste of time, parents can figure out what their kids are exposed to.
当开发一个应用程序或者是其他的处于用户空间的程序时，开发者必须考虑其他人写的代码----操作系统，库函数，还有其他程序，等等。

许多网站并没有使用任何应用框架：你就写你要的程序和尽可能到处复制贴上你所需的程序。

惟一的例外是，具有较少写活动和不可预测的查询工作负载的应用程序，这种应用程序难于定义更明确的索引。
The only exception could be applications with low write activity and unpredictable query workload such that more specific indexes are hard to define.
相反，您不必写一个单独的处理程序，而是编写两个内容处理程序：一个程序对字符串执行传址方式的比较，另一个则不这么做。
Instead of writing one monolithic handler, you can write two content handlers: one that performs reference comparisons on strings and another that does not.
如果你的程序要和另外一个用某种语言写的程序打交道，那么通常新程序采用同样的语言是个好选择。
If you're writing a program that has to work very closely with a program written in a certain language, it might be a good idea to write the new program in the same language.
s锁允许使用只读查询的并发应用程序访问目标表，但是防止应用程序写数据到表中。
The s lock allows concurrent applications that use read-only queries to access the target table, but applications attempting to write data to the table are prevented from doing so.
同样的道理，当聪明的程序员，写程序的时候，他们是想让自己减少敲键盘次数。

它之所以被称为Silly因为，它实在是一个相当丑的程序，当然以这种方式去写一个程序是不对的。
And it's called Silly because it's really a rather ugly program. It's certainly not the right way to write a program to do this.
很多程序都是“setgidgames”，以使得只有游戏程序可以修改“topten”分数，而且存储这些分数的文件的主人是games组(而且只有这个组可以写)。
Many programs are "setgid games" so that only the game programs can modify the "top ten" scores, and the files storing the scores are owned by the group games (and only writeable by that group).
许多编程编得很好的程序员写注释不行，而编得不好的程序员能写出出色的注释。
Many good programmers comment badly, and many bad programmers produce excellent comments.
他曾经用像Unix程序sed、awk和sh，以及用c写的程序的语言执行过各种各样的任务。
He had been using languages like the Unix programs sed, awk, and sh, along with programs written in C, to perform a variety of tasks.
目前为止咱们写过的程序还都没有接收过用户的输入。这写程序每次都是做一些同样的事情。
The programs we have written so far accept no input from the user. They just do the same thing every time.
在你写你的第一行应用程序代码前，或者在你部署一个应用程序前，你必须确定你正确部署了你的环境。
Before you write your first line of application code, or before you deploy an application, you must ensure that you configure your environment correctly.
这个问题在于你写的那个程序实际上并不是你想要写出的那个程序。
The problem is that the program you wrote is not the program you wanted to write.
为了写日志给一个管道，简单地用管道符|替换文件名，跟随可执行程序名字，这个程序应该在它的标准输入上接受日志项。
In order to write logs to a pipe, simply replace the filename with the pipe character "|", followed by the name of the executable which should accept log entries on its standard input.
你会发现由爱好者们写的程序，没有附加限制：游戏、图像、办公套装、字体，每一种想象得到的桌面工具和小程序。
