Ubuntu仓库里有个weather-util包，可以用来查看天气信息。weather工具从weather.noaa.gov网站获得天气信息，对美国的城市可以直接用名字查询，其他国家只能使用id查询。id的规则和weather.com不太相同。 中国的天气站点id可以在这个页面上查到。比如南京ZSNJ，上海浦东ZSPD。使用weather工具查询： weather -i ZSNJ Current conditions at China (ZSNJ) 32-00N 118-48E 12M (ZSNJ) Last updated Feb 18, 2010 – 08:00 AM EST / 2010.02.18 1300 UTC Temperature: 35 F (2 C) Relative Humidity: 59% Wind: from the SSW (210 degrees) at 4 MPH (4 KT) 简化操作，可以在$HOME下创建.weatherrc文件，形如 [default] ID = ZSPD [nj] ID = ZSNJ [...]

大年初一翻旧物，找到一些让人颇有感触的旧物件。2004年买的RH9，2005年夏天买的Fedora 4。前者至今还安装在我家最旧的电脑里，虽然我都忘了它的样子了。 包装 手册 CDs 这个代理商里仁软件似乎已经倒闭了。

Very glad to announce another daily-coding work: an extension for gnome deskbar applet to search and launch virtual machine. There is a plugin for gnome-do that does the same job. That’s what I create the the plugin for. I switched to deskbar because gnome-do’s Do.exe reminds me nightmares when I was a M$ Windows user. [...]

I’m sorry for the long title. Due to lack of documentation, it’s not easy to use python xpcom api from virtualbox sdk. The code below is just a sample that lists your installed virtual machines. It works on linux with VirtualBox OSE 2.0.8. Hope useful to you. import vboxapi vmsg = vboxapi.VirtualBoxManager(None, None) vbox = [...]

Glad to announce my works this morning: A simple heatmap API based on HTML5 canvas. The programming interface is rather simple now. To create such a heatmap, you just new a heatmap object by: <canvas width=”300″ height=”215″ id=”canv”></canvas> heatmap = new HeatMap(“canv”); Then read your dataset and push data into the heatmap: heatmap.push(x, y, value); [...]

今天在工作用的ArchLinux上安装了用Openbox取代了GNOME桌面，感觉良好，回来尝试一下在Ubuntu上也做同样的事情。不料遇到问题，在完成基本的配置之后，Openbox Session无法启动，总是自动跳回gdm。查看.xsession-errors，是gnome-setting-daemon报错： (gnome-settings-daemon:2519): GLib-CRITICAL **: g_propagate_error: assertion `src != NULL’ failed 既然是gnome-settings-daemon报错，就在.config/openbox/autostart.sh中注视掉和gnome-settings-daemon相关的部分： # Make GTK apps look and behave how they were set up in the gnome config tools #if test -x /usr/libexec/gnome-settings-daemon >/dev/null; then # /usr/libexec/gnome-settings-daemon & #elif which gnome-settings-daemon >/dev/null; then # gnome-settings-daemon & # Make GTK apps look and behave how they [...]

Simple-xml is an object-xml serialization and de-serialization framework. It’s featured by annotation-driven, light-weight and self-contained. In simple-xml, pojos that will be serialized are annotated with @Root, @Element, @Attribute or @Text. The problem is, when handling with inheritance, if the actual type is different from declared type, simple-xml will add a “class” attribute for de-serialization consideration. [...]
