Top five things Linux can learn from Microsoft
Jul. 20, 2006
Linux does a lot of things right -- open-source
,
security, reliability -- but it's far from perfect. In fact, Linux and
its vendors could stand to learn a few things from Microsoft. Yes,
Microsoft. Like what? Here's my list of the top five things that Linux
could learn from Microsoft.
1. MSDN
Spread the word:

With Linux and open-source software
,
all the code is open, so any developer can leap right in and start
working. That's grand, but what if you don't know where to start? What
if you're not really sure, or perhaps not too sure, about what's the
right way to program for a given project? What if you want to write
something new and useful... but you discover three months into your
project that you're duplicating work that's been done a dozen times
over?
There are no easy-to-use guides on how to program
successfully in open-source. To learn how to do it right, usually takes
a couple of years of getting to know the lay of the free software
landscape.
With Microsoft, however, there's the
Microsoft Developer Network
(MSDN). MSDN provides developers with help in writing applications
using Microsoft products and programming tools. And, when I say help, I
mean: Help.
There are well-written tutorials, best practices
guides, the latest betas and production copies of operating systems and
software, software development tools, code examples, online
communities, endless articles on the nuts and bolts of Microsoft
programming, and on and on. Best of all, it's all well-organized, so
that you can easily learn what you need when you need to learn it.
MSDN isn't cheap, but for Microsoft developers it's worth every penny. Open-source sites like SourceForge
are very handy, but they're more useful as project incubators than as
educational sites. No, open source and Linux don't have anyt

使用select函数可以以非阻塞的方式和多个socket通信。程序只是演示select函数的使用，功能非常简单，即使某个连接关闭以后也不会修改当前连接数，连接数达到最大值后会终止程序。
1. 程序使用了一个数组fd_A，通信开始后把需要通信的多个socket描述符都放入此数组。
2. 首先生成一个叫sock_fd的socket描述符，用于监听端� ......
