iptables in Ubuntu

Posted on October 13, 2011 by Richard Huang

Since 7.10, Ubuntu uses UFW to manage firewall. Well, UFW is easier than iptables, but I prefer to use iptables directly. Keep it less layers. Stop and remove UFW: $ sudo invoke-rc.d ufw remove $ sudo update-rc.d -f ufw remove … Continue reading →

太宽太长？恢复正常！

Posted on December 18, 2008 by Richard Huang

在 Intrepid Ibex 中最招人烦的问题莫过于浏览器中输入框的尺寸超夸张地宽，单行多行皆如此，而且某些应用程序（比如 Eclipse）的按钮也很宽很宽。难看的恨。 我在 launchpad 上给 Ubuntu 开了个 bug，可惜 Ubuntu 团队的人不细究原因直接把这个 bug 分配到 Firefox 组件下，我就觉得修复无望了，因为该问题并非只是 Firefox 独有，其他浏览器（比如 Epiphany）、以及 Eclipse 这样的桌面应用程序也存在相同或相似的问题。 现在真相大白了，这一问题果然不是由 Firefox 引起的，也非我最初听说和猜测的 cairo，而是 pango. 解决问题的方法很简单，升级 pango 到 1.22.4 或以上。我没有找到编译好的 deb 包，只好从源包编译安装。 $ wget ftp://ftp.gnome.org/pub/gnome/sources/pango/1.22/pango-1.22.4.tar.bz2 $ bunzip pango-1.22.4.tar.bz2 … Continue reading →

Ubuntu Font Size Adjustment

Posted on November 16, 2008 by Richard Huang

现在显示器的分辨率越来越高，屏幕上的字也就相应地越来越小，技术倒是在进步了，可眼睛却是真的越来越辛苦了。直接调低分辨率的话，字就不清楚了、发虚、有毛边。所以，使用默认的最佳分辨率、然后逐一修改系统和应用的字体大小设置是正道。 GTK 打开 系统 – 首选项 – 外观，切换至 字体 标签，将字体调节到合适的大小，比如12。系统默认值是10。 GDM 登录界面的字体在 GDM 当前使用的 主题 中控制。比如，若 GDM 使用的是 Human 主题，那么要修改的文件是 /usr/share/gdm/themes/Human/Human.xml，打开该文件，将所有 font 大小相应地调大，比如都加2。 一些应用程序 很多应用程序并非基于 GTK 开发，或者虽然是基于 GTK，但是又不严格遵循 GTK 全局配置。这样的话，就得辛苦一点，独自设置了。 Lotus Notes 在 Notes 客户端的 preferences 中，只能设置使用的字体，却无法设定字体的大小（怪怪的设计 -_-）。可以通过在 notes.ini 文件中加入参数 … Continue reading →
