文档：
http://pubs.opengroup.org/onlinepubs/9699919799/
所有POSIX compliant的操作系统大都遵循，包括Linux(all distro), FreeBSD,
NetBSD, OpenBSD, Solaris, AIX, HP-UX, Tru64, IRIX, UnixWare, OS X等等一众
Unix和Unix-like OS。Windows除外，它有自己的一套Win32 API。嵌入式系统上的RTOS
一般除了自己的一套API外，也包括了POSIX API的一部分子集，比如VxWorks, QNX,
Greenhills Integrity, RTX等等。 |

发帖数: 5958 | 2 当年windows NT底下有win32, OS/2和posix三个子系统。这个设计其实是很合理的也
很牛X的。windows也是一个多架构的操作系统，除了x86，还可以跑在power PC和后来
的Itanium上。大家都觉得windows封闭，那完全是商业行为。
不能说windows的技术比Linux领先，其实当时像Solaris，AIX那些
也都有各自的牛X之处，有些概念现在拿出来都是很牛的。
Linux基本上落后上面这些10年的样子，属于业余水平。不得不说很多事情成功和技术
没有太大关系。 |

因为在sun之前那个年代，很多公司都是卖硬件赚钱
比如ibm，后来m$起来了之后，sun联手m$，两个公司发了一笔财
就是java applet，从那以后，sun就开始拼命转型软件，乃至互联网
那个时代ibm什么也都在转，所有公司都在脱离硬件转型软件，乃至网络
但是硬件还在卖钱，还占有很大一部分市场，但是聪明人都看出来了
硬件，包括系统软件，长远看，没戏
世界的将来是软件的，软件的将来是网络的
sun看到了，ibm也看到了，所有人都看到了
除了还在坚持c++和ee的呆瓜们看不到
所以决战点就在软件上，bea推出了weblogic，ibm推出了websphere
sun搞出了glassfish这些，jboss一度成为最炙手可热的开源公司
但是在这个决定性的战场上，sun华丽地输给了ibm和bea
glassfish等一直没有在市场上赢得对weblogic等胜势
所以当硬件和系统软件逐步开始萧条之后，sun自然就挂了
所以决定性的原因是sun的软件，尤其是java之上的软件做得很糟糕
这才是胜负手，至于solaris，spark（server)，那都是扯蛋

发帖数: 5958 | 15 这个我以前科普过的。Windows NT是一个非常牛B
的模块化设计。NT内核的功能是通过不同的subsystem
expose出来的，包括一个win32 subsystem和posix subsystem。
win32 subsystem和win 95/98的win32 API二进制兼容，就是
一般人看到的windows。win 95/98和NT/2000/XP内核完全不同，
但是能实现app的二进制兼容，就是通过的win32 subsystem
实现的。Posix subsystem一般人不知道，软软自己也不推广，
但确实是标准的posix。上面可以装一套windows services for unix，
然后config, make, NFS, sh啥的都有。这个十多年前我都玩过的。
从技术上来说, win32 API比posix是不是更科学难说，但从技术上来说要
复杂得多，投进去的钱也要大得多，就软软来说赚到得钱也大的多。
谁能预料得到陈年往事又要被挖出来。真是非战之罪也。

发帖数: 21367 | 20 你看了原话的吧 :) "安全系统研究成果最多"，而不是“操作系统安全性最好”
众所周知，OS X和Linux下的已知病毒比Windows下少了无数倍，这说明它们
比windows vulnerability更少吗？:) 你可以在家装个AIX，用lynx文本
上网，浏览中中木马的概率几乎为0，从这个角度来说，非常非常安全。
回到一直在说的浏览器和网络银行解决方案吧 :) 信不信都随你，虽然都是不百分百
安全的事情，但IE比FF还是好一些，safari是不能用的，胡调IE的一些东西。
当然你要是已经中了keylogger，啥浏览器都一样。

If you use OSF, SCO, AIX, Solaris,

echo \\033\[37\;0m
will change to original set

If you use Linux, BSD which sh is really bash
execute
bash
echo -ne \\033\[37\;0m
Or you can set any background color and forground color as you like.
BTW, you can modify "reset" to do it, I fix it.

发帖数: 4193 | 34 You have to understand what "performance" really means. Number of arithmethic
operations per second? Except computational scientists who cares. Ease of
administration and interoperatibility are more important for most people.
When you compare two systems, you should ask: does it have all the software
I want? Does it support the popular network services? Is it easy to
maintain? Blah, blah. If the answers are no, then what "performance" it has
is nothing but shit.

It's just one easily measurable number, so people use it as
a relative reference. Also, performance means more than just
the ability of doing number crunching. I/O speed, among
others, also matters a lot in system performance. So people

Right, the whole industry has this love-hate relationshop
with benchmarks. Everyone downplays the importance of
benchmark, and yet everyone uses it. There are a set of de
facto benchmarks that are typically viewed as industry
standard. Like TPC-C for OLTP, and VolanoMark for Java
performance. Actually Wintel platform always leads the
chart. But which business will bet their core operation on
Wintel?

I have tow IBM RS/6000 machines now running AIX-4.3.
I want to know if I can install linux on it.
After some research, I cannot find information on linux installation
of these specific machines.(Some RS/6000 models can run linux, but I
cannot find my models in the list)
First I want to make sure I get the right machine type.
On one machine, there is a printing "IBM RISC System/6000 39H", and
next to it there is another printing, which I think is the serial
number,"7012 26-80853".
