This is taken by a Motorola Droid taped to the top of a remote control car.

Just need to find a cool video conferencing app to load on the Droid so I can drive it remotely!

I was looking for all the really large files on my Mac and couldn't figure out how to do it.  After searching the web, I found this easy solution. When you have no other windows open click on cmd and F. This should open the finder window.

Last weekend the family and I went for a walk in the Assabet River National Wildlife Refuge.  It was snowy but nice.  We hadn't been there since the summer and were impressed by all the work on the road that has been completed (even though it was under snow).  We had always hoped that they were going to open up the roads to bike traffic and we checked the signs again, and they in fact did open it up.

You are now allowed to ride your bike on the roads!

I completed my first video for CompositeWeb this past weekend.  It is an overview of CompositeWeb's Hosted Intranet product.  I used Jing to record it and was happy with the results although it took a lot longer then I had expected it to.

If you have any feedback let me know in the comments.

For most people this is probably not pertinent as you don't want to be deleting any of your hidden system files.  I had an issue the other day were I needed to delete some svn information off of my computer before being able to check it in.

I had copied a bunch of files from one subversion location to a new one using finder and caused a bunch of issues with the new subversion site.

In order to delete out the old subversion data, you need to enable the viewing of the hidden files, then delete all the .svn directories, then check everything in.

To view hidden files, open up terminal editor and type in this:

defaults write AppleShowAllFiles TRUE killall Finder

To hide all the hidden files after you are done:

defaults write AppleShowAllFiles FALSE killall Finder

Good luck.

Here's another item that I am note sure I knew before, but now I do.  When you are running a query of queries and trying to do a sort on it, the one thing you have to remember is that the field names are case sensitive.

So what you need to do is cfdump the query you are using in the query of queries and copy the field names that show up exactly as shown.  Then it should run just fine.

I was surfing around YouTube and found this video of a personal airship!  How cool would that be.  Anyway, the blimp is so delicate you could not use it outside.  But then I got to thinking that this would be an awesome revenue generator for indoor stadiums.

I have no idea how much time stadiums are not used, but I bet they could get a bunch of people to pay $50 per 30 minutes to fly one of these blimps around.  I sure would.  And they would be doing this on the days that the stadiums are not generating any revenue.

So if anybody owns a stadium, please look into it and let me know where the reservation form is located so I can sign-up!

I was recently integrating OpenID into my SaaS Intranet offering over at CompositeWeb.  I started working with the opensource project OpenID at riaforge.  It worked great, but then I found the RPXnow site and thought it would provide a lot more flexibility in the future and provide for an easier to maintain interface.

I didn't find any information on how to implement it with coldfusion so I thought I would post what I figured out.
