My colleague uses "ar". But I think it's not right. |

VS2005下面很简单的一段代码，
ofstream os("f", ios::binary);
float iii = 7.00001;
os << iii;
os.close();
结果得到的文件f有7个字节，显然是text mode
有谁知道这是咋回事？ 多谢

我觉得不是，如果bin模式存，应该只会占用4个字节

昏，当然不是。
float是4个bytes，7.00001的text表示就是7个bytes |

发帖数: 204 | 4 环境：winxp, visual studio 2005, OpenGL ES simulation from
Imagination.(power vr)
问题：在release mode下ctrl+F5会导致程序崩溃。对画框unhanded
exception. 用F5或在debug模式下无问题。
检查：注释掉绝大部分代码。只留下contructor和生成open gl窗口的程
序，constructor 内无任何动态内存的分配函数。所有成员都已赋初值。
有的成员是整形或字符数组，但总的大小不超过2048字节。仍然出现
同样的问题。
换成visual studio 2008, 则没有问题。程序是c和c++混写的。请教各位
大侠这个有可能是原因吗？
是否应关掉优化看看？
多谢了 |

发帖数: 310 | 5 I am using bash in Ubuntu. In order to enable vi mode for the command line,
I put the following line into the .bashrc file.
===========
set -o vi
==========
When the command is very long, the key "v" is pressed and then the "pico"
editor is invoked by default. How can I disable "pico"? I prefer editing
long command line in vi editor.
Thank you. |

It is fxxking impressive.
incredible design decisions.
incredible coding.
Why people designed and implemented such high quality
software for FREE? It is really evil because it may potentially
break the business loop of others.
Anyway,in last month,I had more fun from learning/practicing Emacs/vi
than playing basketball. |

发帖数: 3102 | 11 这 folding mode 在做长篇大论的时候太重要了，可是俺一直没搞定。
1、folding 了之后没有足够的提示信息。比如说，fold 了一个 figure，显示 [f
igure]，但俺更希望还显示 \label 或 \caption，比如说 [figure]{fig:FooFigu
re}。咋整？
2、光标经过 folding 的部分时，比如原来的 figure 部分有 20 行，那么俺得往
下走 20 行才能越过那个 [figure] 的标记。
3、为啥不能 fold section/subsection 之类的没有 \begin \end 圈定的部分？该
咋整？设 outline 么？
各位是如何解决这些问题的？多谢哈 :)) |

我想让A显示得大一些，这样在A周围就没有那么多空白了。。。 |

google了一下好像该试的都试了,还是改不过来
不过好像性能没影响
vista硬盘性能还是4.7
用别的benchmark还是30多MB/s
是5400rpm的2.5"的笔记本硬盘
大家看看要不要再研究下,还是显示的问题? |

发帖数: 183 | 32 It is OK, I can accept that I made mistakes and the fact that I forgot
things I used to know.
OK, I fixed my last question, I will say if it is in acidic condition (
Positive mode), the bottom two -OHs are basic enough to take the H+.
When I was doing my chores, I realized no matter what, alcohol should be
more acidic than basic, it is my bad.
I still have questions, but without the spectra, it is hard to discuss
further.
Thank you anyway. |
