Go Back and Forth Fast in Preview

If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.

The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).

The Postini Test Begins

Send Article to a Friend

I'm mad as hell, and I'm not going to take it anymore! In particular, what I'm hoping I'm not going to take is spam destined for the tidbits.com domain. As a result, our good friends at digital.forest have set us up with a review account with the anti-spam service Postini, which I'll be turning on sometime within the next week (digital.forest resells Postini services to anyone for $1 per protected account per month).

For those that haven't heard of it, Postini is an anti-spam service that protects an entire domain from spam, although it's possible to prevent mail to certain addresses from being filtered (at least initially, we'll set this option for all of our auto-reply and mailing list addresses). To enable Postini to filter all the mail destined for tidbits.com addresses, I'll change the MX records in our DNS setup so all incoming mail goes through Postini's mail servers, where it can be checked for spam and viruses, before being forwarded on to our mail server for delivery.

I mention this move in advance because we simply don't know how effective Postini will be, and it's possible that mail to me, or anyone else at the tidbits.com domain, will be filtered out by Postini until our users adjust the settings appropriately. In reality, we of course hope that Postini will be equally as accurate as the client-side filters many of us already use; Michael Tsai's SpamSieve remains about 99.6 percent effective for me, but as my spam volume has crept into the 800 to 1,000 per day range, just receiving and processing that amount of spam has become onerous. Worse, scanning my Junk mailbox in Eudora for false positives has become essentially impossible; I can sort by spam score and look at the lowest ranked message, but if I think I've missed something, a search across the Junk mailbox is the only real hope.

I'll report back on how well Postini works for us and how easy it is to use in a month or so. In the meantime, I'm hoping for the best, which would be an almost complete drop in spam with no additional lack of reliability introduced into our email services. Fingers crossed.
