193 * You can spin down the disk while playing MP3, by setting disk readahead
195 once, and will then spin down while the MP3 is playing. (Thanks to Bartek
203 * In syslog.conf, you can prefix entries with a dash `-` to omit syncing the
204 file after every logging. When you're using laptop-mode and your disk doesn't
205 spin down, this is a likely culprit.
