xmlhttprequest: add interactivity to your static web pages
Excerpt: I've been following the development of implementations & uses for XMLHTTPRequest, which is apparently a javascript function that has been around for awhile but is only now getting attention (partly because MSIE does not support it natively except as an ActiveX thing). Basically, from what I've been able to see and read about, this gives web designers/developers a way of adding implicit interaction between...

PHP Oddity
Excerpt: Discovered a little oddity with PHP and Firefox. In my root .htaccess file I have: php_flag zlib.output_compression On php_value zlib.output_compression_level 9 This causes all PHP files to be compressed, if the user agent accepts compression. My error page is also a PHP script, mostly to trap the referring URL and include that in the page. Entirely by accident tonight I discovered that the error...

More on XMLHttpRequest
Excerpt: Some more links on XMLHttpRequest, which I wrote about here: At Adaptive Path, Jesse James Garrett writes Ajax: A New Approach to Web Applications. JJG defines Ajax as: standards-based presentation using XHTML and CSS; dynamic display and interaction using the Document Object Model; data interchange and manipulation using XML and XSLT; asynchronous data retrieval using XMLHttpRequest; and JavaScript binding everything together. The article continues...
Bloglines & Forbes.com rss feeds
Excerpt: I noticed a minor irritating problem with the Forbes.com RSS feeds, at least in their interaction with Bloglines. The feeds are RSS 2.0 format and include a <link> element. Bloglines uses the URI in the <link> element as though it were a <base> URI for all other URIs in the feed, so you end up with links like http://www.forbes.com/news/http://www.forbes.com/technology/2005/02/24/cz_dl_ibm.html?partner=rss for IBM's Growth Engine Sputters....

v3.1
Excerpt: Minor updates. Of course, I tested this with MSIE and Firefox on a PC, faced off against Safari, Firefox, and MSIE 5 on a mac. I made one little tweak to the margins and it totally destoryed the layout on MSIE for no good reason. I also think I've fixed the comments. Not that I expect any other than links to poker, phentermine, vioxx,...

Wow: Using Google Maps to display Chicago CTA routes
Excerpt: Google revolutionized the online map world when it launched Google Maps. Another revolution is brewing with a Firefox extension called GreaseMonkey. GreaseMonkey allows one to client side JavaScript scripts which can modify various aspects of a web page (gross oversimplification). Combine the two and you get things like the Craigslist-Google Maps mashup of a couple weeks, and now this: Chicago Transit Authority map on...

Excerpt: Nivi : Greasemonkey will blow up business models (as well as your mind): Greasemonkey lets you mash-up websites. It lets you extend and script websites and integrate that script right into the original site as if the designers had intended it to be there. It lets you use their web site, their data, their servers, their work to serve your purpose and function. There...

Tagging for Fun and Finding
Excerpt: OK/Cancel » Blog Archive » Tagging for Fun and Finding Tagging in general works well when the terms being used for tagging are used for aggregating like items. Tags can be helpful when the work used for the tag is even in the information or object being tagged, it is more helpful when used to on information and objects where the word does not...

Don't depend on my markup for your application
Excerpt: When I was a certain corporate webmaster, I'd frequently be escalated because of a change in the markup for www·ibm·com. See, people would write applications which screenscraped something off www·ibm·com, perhaps the stock quote, our news headlines (which was perverse since we had a CDF feed from like 1997 on), whatever. People would screen–scrape and rely on the precise structure of the page, rather...

Elsewhere: a look at IBM's web feeds
Excerpt: I got distracted tonight by the discovery of a large batch of RSS and Atom feeds at IBM. Since I had ten thousand other things to do, of course I spent a couple of hours looking around at the feeds and found some issues which I've written up here...

Two links on highly scalable databases
Excerpt: SQL Databases and Internet-Scale Applications: When you build web applications that have to scale up to millions of users, you sometimes end up questioning almost every aspect of your design as you hit scalability problems. Where have all the good databases gone: Users of databases tend to ask for three very simple things: Dynamic Schema Dynamic Partioning of Data Modern Indexing My message is...

Some requests are my command
Excerpt: I received a complaint today about the automated posting of links from my del.icio.us account. Now, I think it's a nifty, short-cut way of blogging stuff I have read and thought to be interesting, however at least a portion of the large audience for this site disagrees. So I have recoded the templates for the site, at great personal cost and effort, to include...
