Mail.app has a curious feature, which is interesting if not immediately useful.

If you put a URL in the Subject line of an email, and some text in the body of the message, Webkit (or whatever handles the text in Mail) turns it into hyperlink.

As pointed out in a tip on MacOSXHints , it doesn’t work if you leave the body of the message blank.

The result is a clickable subject in the delivered email:

It’s not clear to me how users could make use of this behaviour, especially since you need to put text in the body of the email to trigger the parsing, text which might as well be the URL itself.

Still, it’s something to blog about ;-) mail.app, apple mail, webkit, text, url, oddity, trivia

Danish blogger Henrik Kramshøj has posted a very impressive screenshot of Activity Viewer in overdrive, in the process of writing 30,077 changes to disk.

As far as I can tell (thanks, InterTran ) the burst of activity was caused by changing internet service providers and email addresses at the same time:

Today sweat my laptop by one long-winded disk by that synchronization whole bulk item, because I’ve switched internetudbyder, addresses and tænkte it was pÃ¥ the time that bulldoze awhile up.

Machines are not about to make human translators obsolete any time soon.

Still, the picture is worth a thousand words in any language:

mail.app, apple mail, trivia, activity viewer, the labours of Hercules, caches, writing changes to disk

A German Mac user has posted what he says is a screenshot of Mail.app‘s notification badge after your unread mail count reaches a certain number.

I’ve never seen this myself. I wonder what level of negligence is required before you see it.trivia, mail.app, apple mail, notification, badge, joke, unread emails, email
