提醒闹铃功能（不是指通知，通知没声，不容易第一时间发现，小范围走开时更是看不到，受限较大，报警铃声最好，外出时，邮件，短信提醒最好）
可以提高各种效率，我认为很重要，经过一翻查找，
发现提醒功能很强大，但也被提及的很少，
甚至可以远程的服务器完成命令后自动发邮件或短信通知管理员或用户。望交流更多。
找到两个好用的ubuntu提醒软件，其它linux或也可用，

Fully customizable and extensible talking alarm clock.

This package has a complete graphical front end with which a user can set an alarm to wake the computer - from poweroff if possible - and read a user-defined text. This text can grab relevant information (date, time, weather, Evolution schedule and tasks, news from an rss feed, number of new email messages, etc.) and speak that as well, or play music, all as defined by the user. More capabilities can be added to the alarm via a complete and simple plugin system. Supports multiple alarms.
