WangLu's Notes

症状是VNC远程连接后，画面显示一帧就不再刷新了 （但是鼠标键盘在本机好像是有响应的） 以前讨论过这个问题 http://coolwanglu.blogspot.com/2011/01/compizfglrxvnc-problem-of-vnc-server.html 今天再次遇到了，只是现在我的电脑是ATI的卡 vino不太好用，用x11vnc的时候出现消息 29/04/2012 21:14:17 XDAMAGE is not working well... misses: 166/216 29/04/2012 21:14:17 Maybe an OpenGL app like Beryl or Compiz is the problem? 29/04/2012 21:14:17 Use x11vnc -noxdamage or disable the Beryl/Compiz app. 29/04/2012 21:14:17 To disable this check and warning specify -xdamage twice. 用 x11vnc -noxdamage -once -display :0 可以正常使用，但是由于不是增量显示的，网络压力会很大 在 https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/772873 看到一个 workaround 是说在ATI Catalyst Control Center (Administrative)里打开 tear free 这个选项 我试了一下，果然管用。 以后不用-noxdamage也能正常使用了 另外-once这个选项太好用了  The symptom is after a successful vnc connection, the window stopped refreshing after the first frame. (But the keyboard and mouse seems to be responded on the remote machine) I've discussed about the problem before: h...

1. 让c#程序崩溃时的堆栈信息显示行号： 把相应的pdb文件放到同一目录 2. Ubuntu 莫名启动慢，硬盘无反应 我的原因是这个 https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/839595 需要在 /etc/network/interfaces 文件中删除 "auto eth0" 3 .Firefox 词典插件推荐 Dictionary Tooltip。配合我常用的dict.cn效果不错 参数 site url: http://dict.cn/mini.php?q=$$ scroll to element: word-key 4.

1.SingleCompile 是一个不错的 vim 插件，用于快速编译运行单个文件 2.vim 命令 :cope 查看所有编译错误 3.tsocks 从网络库层面给程序包装一个透明socks代理 4.删除 Messaging Menu 不需要的条目： mkdir -p ~/.config/indicators/messages/applications-blacklist/ 从 /usr/share/indicators/messages/applications 找到不需要的文件，在上面那个目录里创建链接 5.vim 的 wildmode 和 wildemenu 可以定制 vim 自动匹配（例如文件名）的模式 6.easytags 可以让vim根据tags进行语法高亮 7.让vim可以像Visual Studio一样在输入行末的分号或者右大括号时可以自动格式化代码 function! WL_auto_format() let curline = getline('.') let curcol = col('.') if match(curline[curcol :], '\S') == -1 " current char is curline[curcol-1] let c = curline[curcol-1] if c == ';' execute "normal \ =$" elseif c == '}' execute "normal =%%" endif endif endfunction autocmd Filetype c imap ; ; :call WL_auto_format() a autocmd Filetype c imap } } :call WL_auto_format() a autocmd Filetype cpp imap ; ; :call WL_auto_format() a autocmd Filetype cpp imap }...

1. Linux 查看程序访问的文件(类似filemon/processexplorer): strace -e trace=file foo 2. mod_python 编译出错： 参考 http://blogold.chinaunix.net/u/19834/showart_2127433.html connobject.c142行 !(b == APR_BRIGADE_SENTINEL(b) 改为!(b == APR_BRIGADE_SENTINEL(bb) 3. virtualbox 修改 host key: file -> preferences -> input 4. live meseenger 显示所有好友离线： 去控制面板->添加删除程序->修复live meseenger 也有说删除appdata的 5. linux 手动添加dns： 修改/etc/dhcp/dhclient.conf (可能还需要/etc/dhcp3/dhclient.conf)，加入 prepend domain-name-servers 8.8.8.8; 6. Windows 7 godmode 建立文件夹，改名为GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} 1. Monitor files accessed by a process on Linux (like filemon/processexplorer) strace -e trace=file foo 2. cannot compile mod_python from http://blogold.chinaunix.net/u/19834/showart_2127433.html at connobject.c line 142 change !(b == APR_BRIGADE_SENTINEL(b) to !(b == APR_BRIGADE_SENTINEL(bb) 3.

1. fontregister: Windows 下没有管理员权限时安装字体的小工具 2. 在Windows下Putty用Linux字体时可能需要选上Cleartype选项 3. x11vnc: 可以在终端开一个vnc server连接到一个已有的X会话上去 4. pomodoro: 工作25分钟，休息5分钟。一个有趣的工作模式 5. network-manager的共享网络模式(shared to other computers)似乎变的好用了（以前我这完全不能用) 6. Firefox添加书签时没有“在边栏显示”的选项，但是去书签管理看属性还是有的。 1. fontregister: a tool that allows you to register new fonts in Windows without admin privilege. 2. In putty on Windows, you may need to choose the "Cleartype" option when using Linux fonts 3. x11vnc: to create a vnc server that connects to a existing X session 4. pomodoro: work for 25 minutes, then rest for 5 minutes. A good way of time managing. 5. The "shared to other computers" mode in network-manager works well now. 6. In recent Firefox, there's no "load this bookmark in the sidebar" option when you add a new bookmark. However you can still find it, by checking the properties of an existing bookmark in the bookmark manager.
