Hello.

In this first installment of a series about my AJAX application journey, I'm sharing my initial success: learning to think asynchronously. The current app takes user-entered text, sends it to a Yahoo web service (via a local Perl script), gets "interesting" words, and then makes synchronous calls to Technorati for tag counts. This synchronous approach locks the browser, especially with multiple tags. The next version will use a queue and multiple asynchronous XMLHttpRequest objects managed by a thread manager to avoid browser lock-up. This will create a more responsive app where results appear as they become available. Key requirements for v2 include full asynchronicity, XMLHttpRequest management, a generic work queue, background task indicators, and a non-blocking UI. I'm also planning to develop a reusable object model. Read More

My first foray into Ajax was a mixed bag, yielding both valuable lessons and frustrating setbacks. On the plus side, it sparked a deeper understanding of asynchronous coding, cross-browser compatibility (especially between Firefox and IE), and the potential of APIs like Yahoo! and Technorati. It also reignited my interest in Perl and prompted reflection on my blogging practices. However, the application fell short in several areas: it lacked search functionality, didn't reduce bandwidth, had a poor visual design, and wasn't user-friendly or impactful enough to generate feedback or traffic. Moving forward, I'll share my design process and desired improvements, starting with a clear requirements document. I'm eager to learn from this experience and create a more effective application.

I've noticed a difference in how Internet Explorer (versions 6 and 7) and Firefox handle synchronous XmlHttpRequests. In both browsers, you can send requests using JavaScript. However, after the synchronous send() call, Internet Explorer still triggers the onreadystatechange event, while Firefox does not. I need to research which behavior is correct and according to spec. If you happen to know, please email me! Read More

My IE7 Beta 1 keeps crashing when I try to expand my favorites list, although it works fine in collapsed view. This might be related to the large number of unsorted favorites I have, as mentioned in my previous post. Has anyone else encountered this issue or found a solution? Please email me if you have any suggestions. I also plan to re-add searches to the sections below soon. Read More

I've been exploring how Microsoft's Start.com retrieves data from external web feeds. It appears they use a server-side script to tunnel requests to the remote server, effectively acting as a proxy. This workaround is necessary due to browser security restrictions that prevent cross-domain data fetching in Firefox and certain Internet Explorer configurations. Consequently, my AJAX application will need to handle the additional bandwidth required for retrieving data from Yahoo and Technorati directly, as redirecting XMLHttpRequest calls isn't a viable option. Read More

My AJAX application has a minor cross-site data access security issue, similar to one I've encountered in Firefox. A workaround in IE6/7 involves enabling "Access data sources across domains" in Internet Options -> Security -> Custom Level, though this isn't ideal. Read More

I'm curious if my BlogExplosion traffic is genuinely interested in my content. If you found my blog through BlogExplosion, would you still visit if you'd discovered it elsewhere? If not, I'd love to understand why. Your feedback helps me determine if my content resonates with readers or if it's simply unread traffic. Email me your thoughts! Read More

I've created my first AJAX application, an AJAX Technorati Tagger, which can be found here. It allows users to input text, receive suggested Technorati tags (powered by Yahoo's web service), and generate a list of related keywords. It's still a work in progress with some bugs, but feedback is welcome! Read More

I'm developing an AJAX application to automatically generate Technorati, Feedster, and MSN search boxes with relevant tags for my blog posts. It's a JavaScript webservice queryer that uses results from one service as input for another. Currently, it only supports IE6/7 due to cross-domain data source import restrictions in Firefox. I'm exploring JavaScript code signing as a potential solution. The application integrates with Yahoo webservices, with plans to include Technorati and hopefully Feedster. There are security concerns regarding my Yahoo key. I aim to have a prototype available for feedback soon. Read More

My previous blog post was successfully created using Kinlan's Automatic Tag Generator (powered by Yahoo!'s Web service). I'm excited about this and plan to include a link to the Ajax app in the next post. I'm also experimenting with Yahoo search and Technorati integration. I decided to include tags in this post by popular demand. Read More

IE7 Beta 1 now has a feed auto-discovery feature, but it's a bit picky. It only recognizes RSS feeds (no Atom yet) and requires a specific HTML snippet with the correct rel, type, and title attributes. Direct feed links won't trigger the notification, and using text/xml instead of application/rss+xml won't work either. I've updated my blog to comply, but the feed, converted by 2RSS.com and containing ads, still isn't displaying correctly in IE7. Read More

This post lists RSS feeds that aren't displaying correctly in the IE7 feed viewer. Specifically, they don't render in IE7's new format. I'm trying to understand why these feeds aren't working, and I've provided links to a few examples, including the IE7 blog, Channel 9, Scoble's blog, and my own blog. I've since updated this post with more information after speaking with Microsoft's RSS Product Manager (see the link at the top). Read More

I had this brilliant idea to create a merged RSS feed using client-side processing. The idea was to have a main RSS feed that linked to other feeds. My custom XML would include a list of sources. Then, using XSLT in the browser, the client could merge these external feeds into a single view. It worked perfectly locally! However, I hit a roadblock with cross-domain security restrictions when I uploaded it to my server. The browser wouldn't let me pull in feeds from other domains due to security concerns. Additionally, client-side XSLT processing isn't universally supported. So, even if the security issue wasn't there, many feed readers wouldn't be able to display the merged feed. In the end, the project failed. But, I learned a lot about browser security, XSLT limitations and client/server interactions! Read More

IE7 finds the RSS feed on channel9.msdn.com but doesn't display it correctly, only showing the raw XML. I'm looking for other examples of feeds that IE7 can't render properly to compile a list and see if there's a pattern or bug. If you know of any, please email me! Read More

I made a typo in the title of my blog post! It should have been "A good test to check out the alpha transparency and I missed it!" instead of "I good test...". Oh well, at least the alpha transparency test worked! Read More

In a previous post, I failed to test the alpha transparency feature. This post rectifies that. I've included an image with a green fade to white against a black background to demonstrate the effect. It may be garish, but it effectively showcases the alpha transparency. Read More

After using IE7 Beta 1, I've found tabbed browsing, while a welcome addition, has a few quirks. Modal dialog boxes lock the entire browser, not just the tab, which is disruptive. Tabs don't have tooltips, making it hard to distinguish between similar pages. Closing tabs requires going to the far right of the screen or right-clicking, neither of which is ideal. And finally, new tabs don't open to the homepage, which would be a useful option. Read More

IE7 introduces the ability to subscribe to any link in your default RSS aggregator. This function allows users to right-click a link and select the "Subscribe in default RSS reader" option. While useful for valid RSS feeds, this feature does not work for other content types. Whether this is specific to Internet Explorer 7, enabled by default, or a result of extensions like RSS Bandit is uncertain. Read More

I've been exploring the RSS features in IE7 Beta 1 and have a couple of suggestions. First, it would be great if we could add feeds to favorites directly from the feeds toolbar button, rather than having to navigate to the feed itself. It's an extra step when we've already decided we like the content enough to add it. Second, I'm curious about how IE7 discovers feeds on a page. Sometimes it works, sometimes it doesn't. Is it just looking for a specific link tag in the head section or is there more to it? It seems to struggle with feeds linked via anchor tags. Overall, I'm enjoying IE7 so far, just want to offer some feedback. Read More

I've been trying out IE7 Beta 1 and have some mixed feelings. While I like the tabbed browsing and the new tab placement, I'm not sure it's the ideal UI. It makes it difficult to compare sites side-by-side and to see open pages in the taskbar like I could with separate windows. A hybrid approach, like Office's per-document window or better taskbar tooltips, might be a good compromise. Also, my ATOM feed isn't being auto-discovered, and I'd like to know how IE7 handles feed discovery in general. I'm looking forward to the improved CSS support in Beta 2, although some rendering bugs are already fixed in this build. Read More
