回复了 coagent 创建的主题 › 程序员 › Git 分支管理与版本发布的冲突问题

最后一段大致差不多。

除了一些神奇的需求，做完一个功能或 bug 都应该放到 master 里吧。某个版本直接打 tag 就行了，没什么只单独属于某个版本的提交

回复了 wwwjfy 创建的主题 › 分享发现 › twitter可以ping通，且https能访问(北京宽带通)，什么情况

@onedayoneapple
@adspe
看ping.chinaz.com的结果确实只有一两个地方有结果

不知道当时facebook开始可以https访问的时候是不是也有这样的先兆~

回复了 rrfeng 创建的主题 › 问与答 › gcc 的 -ldl 参数是什么意思？

-llibrary
-l library
Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.)

It makes a difference where in the command you write this option; the linker searches and processes libraries and object files in the order they are specified. Thus, foo.o -lz
bar.o searches library z after file foo.o but before bar.o. If bar.o refers to functions in z, those functions may not be loaded.

The linker searches a standard list of directories for the library, which is actually a file named liblibrary.a. The linker then uses this file as if it had been specified
precisely by name.

The directories searched include several standard system directories plus any that you specify with -L.

Normally the files found this way are library files---archive files whose members are object files. The linker handles an archive file by scanning through it for members which
define symbols that have so far been referenced but not defined. But if the file that is found is an ordinary object file, it is linked in the usual fashion. The only difference
between using an -l option and specifying a file name is that -l surrounds library with lib and .a and searches several directories.

-L 只是加入搜索库的路径，-l指定要链接的库
-ldl, dl就是库的名字

回复了 gdm 创建的主题 › git › 怎样删掉一些早期版本？

@jsz 肯定没问题，刚才试了下，确实... 什么理由第二个只能edit, squash把当前commit包含进前一个，不需要edit，只需要做完之后编辑commit message就行

@gdm 如果从第一个改，可以直接git rebase -i --root
