Three thoughts on social media for 2010
The hype around social media continues unabated – business, marketing, government, NFPs; everyone is getting involved. But to my mind, we’re still somewhat missing the point. Making it a part of our lives in a way that avoids the hype and adds real benefit to our own lives and the lives of others will be [...]

The next step
An emergent theme of my posts of late has been change. Whether that’s technology, user experience, reform of education, public sector and government, conferences or business (including my own), it’s a constant. Image by trib via Flickr Equally, I’ve had many conversations in physical and virtual environments about change. Those conversations, to my very great benefit, have [...]

Data Centre Fire Suppression Systems

I was visiting a major hosting provider today, and we got talking about Disaster Recovery and how it's all very well to have such a system in place, but until you actually put it into practice, how can you ever really be sure it will work.

This led onto me asking "Have you ever tested your fire suppression systems?"

The response - and a funny one I thought - "no, we've never started a small fire in one of our data centres to see what would happen".

So, how can we therefore be sure that things such as fire suppression will work, should the unthinkable happen?

CF9 EXIF Removal bug

I ran into a little bug in ColdFusion 9 whilst writing an article for .net magazine. Keeping it simple, if you perform two or more write operations on an image (to disk), using the same filename, ColdFusion will remove all the EXIF data stored in the image.

This is listed as bug 75605, which is supposed to be fixed, but it must have slipped through the cracks somewhere. I've pinged Adobe about it, along with a reproducable case, and a workaround.

I came across the bug because I was uploading an image (which writes the image to disk) and then I was adding a watermark, and to save the new watermarked image, it has to once again be written to disk.

This second write removes the EXIF data in the image.

The workaround is to save the watermarked version to disk under a temporary name, delete the original, and then rename the temporary image file to it's proper name.

You can grab the repo/workaround here.

ORM Entity not available? Check your logs
This afternoon I was working on a set of persistent entities called event, eventtype, eventstatus, and eventpriority. Event is the "core" entity with hooks to status, type, and priority. When everything was done I whipped up a quick test: ... [More]

FCKEditor Firefox 3.6 Bug (Year 2010 Bug)
The new version of Firefox broke my FCKEditor! They didn‘t do it on purpose I’m sure, but it did, in fact, break it. I am using what I consider the standard implementation in ColdFusion (that does not come bundled with ColdFusion). I updated my Firefox to the most recent version (3.6) which [...]

What I Learned Today - I blame Ben Nadel for this post...

Okay, the title is meant to be facetious, and attention grabbing. Just so we're all on the same page. But it's not untrue.

Through Ben Nadel's fantastic blog, I learned the practice of creating and scoping a LOCAL struct in a CF function (CFMX7 and CF8), and assigning any other local variable created in the function into that struct. That way I did not need to manage multiple variables, trying to make sure they were all locally scoped. It seemed more efficient.

Well, with the migration of my VPS to CF9 (and the impending upgrade of my work's servers to CF9), I found blog posts talking about how others that had used this practice were finding oddities with their code upon upgrading. It seems that this practice was somehow colliding with the new protected "local" scope within functions in CF9. The new scope allows coders to do exactly what I was doing, only without having to scope that local struct first.

In trying to figure out what changes I needed to make, I went asking around trying to find out if this meant that we no longer had to scope local variables anymore inside of functions, if unscoped variables would automatically get put in the new local scope. To hear and read the documentation, you certainly could come to that conclusion.

Thanks to Ray Camden, I have been straightened out. It turns out this is not the case, and I am not the first to ask him this. He was kind enough to make this topic an entry in his just as fantastic blog.

Bottom line, you don't have to scope things put in the local scope, but you must explicity call the variable in the local scope (local.myVariable). And all other variables must still be scoped for protection.

Windows Server 2003 Security and Files From Other Computers

Another day, another idiotic Windows "security" feature. I'm setting up several new Windows 2003 VMs, so rather than download all the necessary installation files to each machine, I'm copying them from the first one I set up. After mapping a drive and copying some files from the first VM to another VM, I tried to run the Tomcat installer and got the following error:

"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

Even given Windows' stupid notion of what being an "administrator" means (on GNU/Linux either you're root or you're not, which makes perfect sense to me ...), this was a new error to me. Luckily it's easy to work around.

Right-click on the file in question and go to "Properties." At the bottom of the "General" tab you'll see a note next to a "Security" header that reads, "This file came from another computer and might be blocked to help protect this computer." Click the "Unblock" button next to this message and you can execute the file.

Thanks for looking out for me, Windows. Really appreciate it.

Adam Lehman talks about "ColdFusion Renaissance"
So ColdFusion is definitely not dead. If you need further proof of that, you can check out isColdFusiondead.com, where we have a lot of detailed information about that question. But no, it's a funny thing that we hear, you know, every couple of years ColdFusion shifted from companies, from starting at Allaire to Macromedia to Adobe and any time that sort of happens, there's always this "What's going to happen?" sort of thing. But no, thankfully Adobe is really, really helping ColdFusion and
