The scenario you described is not a problem at all for puppet, puppet has a
concept of "template", which are Ruby snippets that can generates
configuration on the fly based on conditions.
Think in server management land, there are a lot configuration duplication
across servers, which configurations go before/after which configurations,
what configuration depend on what other configuration is well taken care of.
I can not imagine any large scale data center deployment will need huma... 阅读全帖 |

called gesture recognition.A snippet from some reviews,

recognition. Lenovo Motion Control lets users wave their hands to perform
some basic actions, like swiping to the next screen — handy if you're

Another way is to use a servlet to generate an image. In your html page, use
an image tag 
to convert the image object to output stream pipe.Here is the code snippet.

发帖数: 254 | 20 That is absolutely correct. However, that was not the point of the question.
Unfortunately Stroustrup did
not give a ctor for this code snippet, but I assume the reference has been
safely initialized. The main
question i am having is if c is a regular const reference, then c.valid=true
in string_rep will be a violation
of constness, thus resulting in undefined behavior, right? |

我现在用的是GoF的template method pattern,
在base class里面写进上面的code,
然后child class override 那几个different code snippet.
这样子class数量暴多
感觉这些被我当作child class的实际上更像是不同的object。
当然另外一个方案就是switch了，这个也太难看了。

发帖数: 372 | 25 Your question is not clear.
You may want to explain what is "automatic space allocation", probably using
the example of another language.
In your code snippet
int i, a[100];
the compiler will allocation space on the stack for an integer i, and space
for integer array a of 100 integers. |

(1) Don't try to write your own code, try to find existing snippet to copy.
(2) Use std/boost as much as you can. It can somehow make your code "look"
better in many cases. And yes usually it does "run" better. It also makes
your code more "c++"
(3) Search on internet for "c++ coding standards/guidelines". You will find
