G'day
OK, this is a cop-out of an "article", and the title is purposely designed to make you go "huh? Update 8?" (they're only up to update 7 so far).
But I notice there's been a bug raised in the installer for update 8 (update: this bug has since been deleted, so the link is dead), so I guess it's due out any day now. After (hopefully) they iron out the bugs, that is ;-)

Survey results: turning a string into an array of characters
G'day:
One of my readers pointed out to me if that if I tarry too long before reporting back on my recent survey about turning a string into an array of characters, then people would lose what little interest they have in the topic. And I admit it's not the world's most interesting topic anyhow. Anyway, I've got 35 responses, so I'll summarise the results.

Bring back named params for <cfprocparam>
G'day
I forgot I was annoyed about this, until I was just reminded about it via Twitter & StackOverflow (no, this is not another gripe about S/O ;-).
Back in the good-old pre-CFMX days, <cfprocparam> used to support named parameters via the dbvarname attribute, eg:

ColdFusion: Adobe's Ugly Step-child
G'day
Here's an ironic observation that I would have made on Twitter rather than a blog article if the former allowed a reasonable size of message.
I was snooping around the ColdFusion docs website for some stuff on CFScript's try/catch, using Google to search the thing as the internal search engine ain't that great. Anyway, as I was closing tabs in my brower, one of those "would you please fill out our pointless survey to help us gather meaningless info which we will then ignore" surveys. For some reason I fill these things out on sites I regularly go to, so I set about filling this one in.

Quick survey / quiz: turning a string into an array of characters
G'day:
This is a bit of a random article. In conversation a coupla weeks back, a colleague questioned my approach to converting a string into an array of characters. Not questioned in a bad way, but my approach surprised them.
Anyway, this festered in my head for a coupla weeks, and popped back into it this morning on the train on the way into work.

Railo website on Raspberry Pi with a public facing domain hosted at home
G'day:
As promised on Twitter last week, here's Chris's article on getting Railo running on Rasperry Pi.
Over to Chris...
So you are a lucky owner of a sweet Raspberry Pi, you have a typical broadband connection, some ColdFusion language skills and you would like to take advantage of all these things and roll out a little Web site hosted at home, independently from any hosting provider, and make it available to your family, friends and the rest of the world? That's exactly what I've done and I thought I'd share a step-by-step guide on how my stack has been set up so you can give it a try, amend it and/or improve it.
The guide is inspired by an excellent article by Glyn Jackson on running Railo on Raspberry Pi that I found very useful when I started this exciting journey. However, the set-up described below differs slightly as the current version of Raspbian does not allow to install the official Oracle Java JDK and for that reason I'm going to opt for OpenJDK instead. And also, we don't need to worry about the SSH configuration as it's enabled by default in more recent versions of Raspbian.
Another deviation from Glyn's config is using a wired Internet connection rather than WiFi.
In my case, the Pi is connected to TimeCapsule with two cables as the wired Internet connection is also coming from it (see the picture below).

Prerequisites
- Standard broadband connection with a dynamically allocated IP address
If you are in the UK, it can be BT, Virgin or any other popular async broadband option (and if you are lucky enough to have an Internet connection with a static IP address, you might want to skip the section covering Dynamic DNS). - A router configurable to forward traffic on port 80 to a machine on the local network
I tested it with an Apple TimeCapsule and a BT HomeHub but other routers should provide that functionality as well. - Raspberry Pi (Model B) with 512MB of RAM
I haven't tested it on the 256 model but you might like to do it at your own risk. - An SD card with the Raspian GNU/Linux distribution installed on it
A step-by-step guide covering this topic can be found on the eLinux site. You will need direct or SSH access to the box with root permissions.
Setup summary
| Possible alternatives | ||
|---|---|---|
| Hardware | Rasbperry Pi 512MB RAM | |
| Operating System | GNU/Linux Raspbian | |
| JRE | OpenJDK 1.6 | Oracle Java provided you are running a soft-float ABI distro (e.g. Debian) instead of Raspbian |
| Web server | Lighttpd | Nginx |
| Application server | Tomcat 7 | Jetty, Resin etc. |
| CFML server | Railo 4 jars | Earlier version of Railo, Open BlueDragon (not confirmed). Adobe ColdFusion is unlikely to run on such limited hardware. |
| Internet domain provider | DNS Dynamic | There is a number of alternative free and commercial services |
Power
One of the great things about Raspberry Pi is its low power consumption which means having it always on should not ruin your home budget. I'm no expert on the electricity stuff but I'm powering my Pi through a USB cable hooked to the Apple TimeCapsule which acts as our home router and is always on anyway so that means there are two devices plugged to one wall socket. Does this configuration mean a decreased power consumption? I honestly don't know but it's certainly nice to have one extra power socket available.In my case, the Pi is connected to TimeCapsule with two cables as the wired Internet connection is also coming from it (see the picture below).

ColdFusion: 2 - Cameron: nil
G'day:
You know how I say I like being wrong? Well it's a good thing I like it as I get a lot of practise at it.

I've just updated the score to be 2-0 because this very same problem just caught me out again, and when googling for the answer, came across this very blog post. Sigh. God I'm thick.
