I’ve been looking over my Expression Engine module, “Link List” and have been tweaking it out and will be working on full documentation on it. I’ve decided to take a couple features out (such as favicon), but nothing that will impede the function of the module itself.
I’ve decided to forego the “updated” part of the module for right now for many reasons. One of them is really performance. Yes, I could have it query the weblogs.com changes.xml or any other changes.xml list and see if it’s been updated there every hour, however, this may or may not work 100% correctly, and well, it’s really very slow.
I’ve also considered using the RSS/XML feeds as a method of seeing if a site is updated, however, while this would be relatively speedy on a “per site” basis, if you have a lot of sites in your linklist, this could prove fatally slow for your site.
So as you can see, I’m still throwing things around on how the “recently updated” thing can possibly work. Without having a dedicated service (imho), it’s really tough to get a good, accurate, and fast method of finding out if a site has been updated.
Once I’m finished with the small things in the app and write up the documentation for it, I’ll release it to the general public. If you’ve gotten the module already, then you probably won’t need to really “upgrade” since it’s essentially the same thing, it just doesn’t have some dialogue boxes that seem to do nothing.
