The (or a) problem with Unix manpages

Unix has three sorts of manpages: excellent ones that clearly answeryour questions, good ones that answer your questions if you read themcarefully, and bad ones that aren't worth reading because they don'tanswer your questions (at least in a way that you can understand).

System status announcements and where your users are

Commentators on my earlier entry brought up usingTwitter for system status announcements and the like.

入場前廢話

若然不是手頭緊絀, 我會不斷後悔沒有購買更多電影節戲票. 剛剛撿起一本舊筆記簿, 居然收藏了去年自己編製的電影節時間表. 按照去年的進度, 我的電影節馬拉松, 在這個時候已跑了一半. 可是, 明天才是我今屆電影節的開
