Amazon CloudFront CFC

By barneyb on January 19, 2010

Amazon CloudFront is a CDN that sits atop their S3 file hosting service to provide caching and geographically dispersed delivery.Â It's all very simple, except security.Â Much like my Amazon S3 CFC's original goal, my new Amazon CloudFront CFC's primary purpose is to ease the creation of signed URLs for CloudFront.Â You can grab a [...]

I learned today, via a letter from the court, that I am no longer married (and haven't been since the 12th). Seven years, five months, and nine days.

Improving the JSON/P Twitter Widget

By barneyb on January 15, 2010

For quite some time now I've had a sidebar widget that displays an excerpt of my Twitter feed on my blog.Â It uses the standard Twitter JSON/P interface for loading the tweets and then a Twitter-provided script (http://twitter.com/javascripts/blogger.js) for rendering them on the page.Â Unfortunately the default installation instructions would have you set up something [...]

Implicit Blocks in Fusebox 5.5.1

By barneyb on January 7, 2010

The XML syntax used by Fusebox since the 4.0 version allows for conditional expressions like these:

In the latter case, the
tags are basically irrelevant, because they provide the same containership and semantic as the tag itself. Fusebox 5.0 and older allowed you to omit the
tags in this [...]

A Personal Update

By barneyb on December 15, 2009

This morning, Heather and I cooperatively filed for divorce.Â This eventuality is old news for some, expected by others, and out of the blue for the rest.Â I have not been forthcoming with this information outside need-to-know situations for a variety of reasons, the primary one being that without any agreement between Heather and I [...]

Even Better CF DB Error Messages

By barneyb on November 23, 2009

A few weeks ago I posted about fixing CF's DB error messages so that they include query params you passed as well as the raw SQL of the query.Â I also supplied a patch for detail.cfm so your SQL renders in a PRE tag for better readability, but didn't make it general enough to handle [...]

I Had a Doubt (About CFGroovy2 and Ehcache)

By barneyb on November 19, 2009

A couple months ago I added Ehcache support to CFGroovy2 as an alternative to the simple HashMap/WeakReference caching that had been there since it's inception.Â I waffled a little bit at the time, but it seemed like the right thing to do.Â I've changed my mind, and removed the Ehcache functionality in the latest build.Â [...]

imageTranslateDrawingAxis is Your Friend

By barneyb on November 19, 2009

I briefly mentioned imageTranslateDrawingAxis in my previous post about Fusebox flowcharts, but wanted to provide a more self-contained example of how it can be used to great effect. The idea here is to draw a house with a window, and to do it in a relative manner, rather than an absolute manner. Consider these two [...]

Fusebox XML Flowchart Generator

By barneyb on November 17, 2009

About a week ago someone posted on the Fusebox mailing list looking for a way to generate flowcharts from his Fusebox XML files.Â Adalon was suggested, but it didn't do quite what he was looking for.Â So I sunk some of my spare time into building such a tool, and even managed to refrain from [...]

Fixing CF DB Error Messages

By barneyb on October 29, 2009

When you're working on someone else's code and you get an error message (because I know you'd never write code that errors), CF usually does a pretty good job of giving you the info you need to debug the issue.Â But for some reason they don't show you query parameters, even though they're included in [...]
