Graceful Exits

Steve compares “graceful degradation” with “progressive enhancement.” Mostly he takes issue (rightly) with the rhetorical spin that the former applies to the idea of building a website. But I think you can compare them with each other as if they were two different types of crowbar instead: two ways of prising open the task in [...]

While Picnik gradually converts the functionality of desktop image processing software into online tools (in the hope, presumably, of being bought up by one of the big players), Flash has found other, more piecemeal uses in augmenting the image and font functionality of your average browser. Hot on the heels of sIFR, which replaces text [...]

Since listening to Garrett Coakley speak at the first Geek Night on the topic of Drupal, I’ve been sniffing round that open-source CMS. He kindly came to speak to us again, and very inspiring it was too. We’re now having a deeper look at it, seeing what it can do, what are its strengths and [...]

Mark Mandel wrote his own version of Coldfusion’s XmlTransform() function, using the underlying Java transform classes. Although one of his annoyances—that XmlTransform() won’t take any parameters—has been solved in CFMX7, XmlTransform() is nonetheless a slow operation, as the transform engine has to be cranked up, the XSL compiled, the transform effected and then everything garbage-collected, [...]

Simon makes the case for disambiguated URLs. He’s right, largely. I would say as a proviso, though, that URLs need to be hackable by the developer as well as by the user. The internal spaghetti that translates URLs to files in Django and Ruby on Rails is an initial barrier to developing with those systems, [...]

I’ve recently been experimenting with calling external commands (mplayer and lame, so you might be able to guess what I’ve been doing) from within a scripting language (Python, although it needn’t have been as it turns out). Bizarrely, the external commands—argumentae intactae—worked absolutely fine on their own, chained together by me, by hand. However, when [...]

For reasons of speed I’m currently embedding Java in Coldfusion code. Given Coldfusion is built on Java, and can instantiate Java objects through createObject(”java”, class_name), you’d think that’d be reasonably easy. But the boundary between Coldfusion and Java is like the gap between two halves of a broken bone: jagged, bleeding-edged and painful when coerced [...]

I couldn’t find this on the Goggle, so: if your Coldfusion template occasionally furnishes you with the unhelpful, lineless error:
can’t load a null

then this might be caused by the following. You may be trying to compile a function using something like this code:

<cfset bar = “something”>
<cffunction name=”foo”>
    <cfargument name=”bar” default=”#bar#”>
</cffunction>

At the point of trying to interpret [...]

If your web application ensures that all your incoming CGI variables are free of the most common source of malicious site damage, can you stop worrying?
I wondered this as I got far enough into a PHP publishing system that I had to start thinking about adding new content through the system (rather than just jamming [...]
