Set Password Activation Time in Snow Leopard

In Snow Leopard, you can now set an amount of time after your Mac goes to sleep or engages the screen saver before it requires a password to log back on. In Leopard, the option was simply to require the password or not. Choose among several increments, between 5 seconds and 4 hours, from System Preferences > Security.

JavaScript Yourself Anonymous -- In response to letters on hiding your email address on a Web page to avoid spammers sucking it down, Joseph McLean <flux@thecentre.com> wrote us with a nifty JavaScript-based solution, which he offers for free:

Brandon Munday mentioned how he removed all "clickable" mailto links from his Web site to thwart the evil address-collecting spiders. Making a site non-clickable is so counter to the Web's nature that I became convinced there had to be another way. And there is - if you turn to JavaScript for aid.
JavaScript is not ubiquitous technology, but this can also work in your favor, because spiders don't speak that language - and most of your human visitors have browsers that do. Here's an example I cooked up in five minutes.

<script language=javascript>
<!--
// SpamProof Mail Script 1.0
// by Joseph McLean <flux@thecentre.com> - freeware
// Linktext is the text you want folks to see and click upon.
// email1 & email2 are the text on either side of your
// email address's @ sign.

var linktext = "Email Me!"
var email1 = "jsmith"
var email2 = "where-ever.com"

document.write("<a href=" + "mail" + "to:" + email1 + "@" + email2 + ">" + linktext + "</a>")

//-->
</script>

This chunk of code can be pasted into your Web page's HTML at any point. Some old browsers don't support JavaScript, but they won't hit an error - the mail link will simply be invisible (as it is to spiders).
