Webslices and Revisiting Microsummaries

When the first Firefox 2 beta was released, I looked into Microsummaries, a feature that enables bookmarks to automatically update their titles with information. I concluded they were useful, but not for anything I was doing. The main application would be my Flash site, but it already had an RSS feed for updates, and a microsummary could only really include the most recent item.

Now the first IE8 beta supports Webslices. They’re similar in concept, but can include formatted data (not just plain text) and use microformat-like markup on the web page instead of a <link> element in the head.

I figured with two browsers supporting the concept, I’d give it a shot. I adapted the script I use to generate the RSS feed so that it will also take everything on the most recent day and generate a text file, which is used for the Microsummary title. For the Webslice, to start with I just marked up the “Latest Updates” section of the home page. Since I haven’t installed IE8b1 at home, I’m using Daniel Glazman’s experimental Webchunks extension for Firefox to try it out. Unfortunately the extension doesn’t seem to resolve relative links in its current state.

The real question, of course, is whether either technology offers anything better than what feeds can do now.

I think I’ll end up going the external-feed route for the Webslice as well, since it’ll use a lot less bandwidth than having a bunch of IE installations pulling the entire home page once a day. Plus since I’m using SSI on that page, it doesn’t take advantage of conditional requests and caching, and a static file will. But that’ll have to wait. Lost is on in 2 minutes, and after getting up earlier than usual this morning, I’ll probably be going to bed right after the show.

Update: I checked in IE8, and the webslice does work as expected. A few minor differences: Webchunks pulls in external styles, like the background and colors, while IE8b1 only uses styles in the chunk itself. Interesting bit: I’m marking up list items as entries, and IE8 is actually displaying them as a bulleted list, while Webchunks is simply showing the content.

So it at least works. Maybe tonight or Sunday I’ll see if I can refine it a bit.

Advantages of standards-based design: Compatibility

Microsoft is really pushing for people to make sure their websites and apps are compatible with IE7. Apparently this is a real concern for a lot of people who relied on certain proprietary features, bugs, and quirks in IE6. I guess they figured they wouldn’t have to worry about future versions. (Hmm… I wonder where they got that idea?)

The fact of the matter is, I’m not worried. I tested my personal sites and the sites I’d built for work months ago, using the IE7 betas, and more recently with RC1. I made a couple of minor changes to some stylesheets, but that was about it.

Why? I’ve been writing standards-based code for years. I validate it from time to time, and I test to make sure it works in the latest versions of Firefox, Opera and Safari as well as IE. So the code was already portable.

Plus, anything new I’ve built since January has been designed with IE7 in mind from the beginning.

Most of the changes were to workarounds for IE6. Either stopping them from running on IE7 (if the bug was fixed), or keeping them running on IE7 (if it was done using a CSS hack).

Butterfly wings

Last week I started looking at ways to cut down on false positives in our spam filters. I’ve only seen two in my own mailbox this year, but of course everyone gets different kinds of email. I’ve been trolling the server logs for low-scoring “spam,” looking for anything that looks like it might be legit, particularly if the Bayes subsystem has already identified it correctly but isn’t enough to counteract the score assigned by other rules. (Unfortunately, it’s hard to tell when all you’ve got is the sender, subject, and list of spam rules.)

One item I noticed was a copy of the Microsoft Technet Flash newsletter. I thought this was odd, since I’d gotten a copy of the same newsletter and it hadn’t been labeled. In fact, it turned out that my copy only scored 0.3 points, and the other hit 6.4! (5 points indicates probable spam.) What could explain such a disparity?

New Layout

I finally put together a new layout! I tried to do as much as possible in CSS and leave the HTML as little changed as possible, and when I finished I was able to keep the default WordPress layout as an alternate. In theory I ought to be able to plug in any of the submissions from the WordPress CSS Style Competition as alternates as well.

It’s been tested so far on Mozilla, IE 6, Opera 7, and Konqueror 3.2. It doesn’t use anything more complicated than Fahrner Image Replacement, so it shouldn’t cause too many problems. I’ll try to test it in a bunch of other browsers at work tomorrow.

I consider this a first draft - among other things I figure on adding to the main title banner - but it’s something a bit more distinctive than the out-of-the-box layout we ended up with after the upgrade to 1.0.
