Board Flashbacks

Old Tom

It's time to experiment. If you like the result, please tell us, and we'll continue to run this feature! Board Flashbacks brings back some of the better or more informative board posts which never made their way into The DFN Weekly. This time around, we go "Google-ing" with Voltar, and "console" Old Tom.

thought i'd share some info for those of you who do not want images linked by google... such as in thier pics area.... this is direct from google.com

If you need an image removed from Google's image index we require participation either by you or by the site's webmaster. Please add a robots.txt file to the root of the server. (If you can't put it in the server root, you can put it at directory level.)

Example: If your site is www.yoursite.com/ images/ dogs.jpg and you want Google to exclude the dogs.jpg image found on your site, you need to create a page called www.yoursite.com/robots.txt and on this page you need to place the following text:

User-Agent: Googlebot-Image
Disallow: /images/dogs.jpg
To remove all the images on your site from our index, place the following robots.txt file in your server root:

User-Agent: Googlebot-Image
Disallow: /
This is the standard protocol that most web crawlers observe for excluding a web server or directory from an index. More information on robots.txt is available here.

Okay yes, Cleo's examples in the tutorial match what I was trying to say below. The second item in the list for javascript open() is simple the window's "name". I'm pretty sure it does NOT signify action to be taken. That is, "copy" does not literally mean copy something from somwhere else. It's just a name.

Instead of alternating between the names "copy" and "new" like I suggest below, you could alternate between "1" and "2" or "a" and "b".

Do you see the difference between popping two consoles, and *alternating* consoles?

Cleo's last example pops two consoles. That is, the one page pops both. It's common but deadly practice, for example, to pop one console on entry to the page, and one upon exit.

What do I mean by *alternating* consoles? Some page pops A. A, upon exit, pops B. B, upon exit, pops A. A, upon exit, pops B. And so on.

If you have A pop B, then B pop C, then C pop D, then D pop A, then A pop B, then... that's called a circle jerk or cj. The consoles form an endless loop.

When designing your circle jerk, however, you need to consider the *pages* you're loading, but also the *windows* you're loading. a.html pops b.html which pops c.html which pops d.html which pops a.html and we start over. We've loaded four html pages, but how many *windows* have we loaded?
