Solving technology problems, one at a time
Ever since Firebug got a recent big upgrade, I’ve had problems with it stopping a page from loading whenever there is any javascript error. Since the web is riddled with javascript errors, this has meant
Continue readingAfter installing “Umbraco,” you may get the following error:
The virtual path ‘/install/steps/welcome.ascx’ maps to another application, which is not allowed.
This is because you have installed Umbraco in a virtual directory (not at the web root of the “Default Web Site” in IIS terminology). It is a path problem, easily corrected by fixing the paths in the web.config file.

Firefox wants to use the font “__” on the volume _____”. This
font is not installed. Allow Firefox to use this font?
If I click “Don’t ask me again for Firefox,” it completely ignores it. Really, why do they even have that checkbox if it makes no difference!
This minor irritation became more critical today when it would not stop popping up those messages. Finally, I found the answer:
Open Firefox > Preferences, and click “Content“. Click the Advanced button as shown:
Mail.app has been misbehaving lately on my iMac. It seems to be slowing down in general. I see way too much of the spinning beachball, so I’ve been trying all sorts of fixes, most of

I carry a little Canon PowerShot SD 990 camera everywhere. After all, you never know when you’ll see something worthy of memorializing. But a consequence of my “shoot now, ask questions later” attitude is that memory cards fill up very fast!
A while back, I decided to handle the problem once and for all, and got a 32GB SD card. Most of the time only about 8 GB of it is really full, but sometimes if I shoot a lot of video clips, it can get higher.
This has caused several issues. iPhoto began crashing on trying to display the new images when I connected the camera directly. Switching to a card reader, the iMac (running Leopard) still had trouble sometimes mounting the SD card on the desktop. There were so many files in one folder, I was nearing some kind of ultimate limit for the OS.

I recently hosted a three-person meeting for the purpose of screensharing an application we were all working on. Previous meetings of this type had gone well, but this time we kept having problems with “Another meeting room running” errors which prevented screensharing.

Below is a summary of all the suggestions from the many comments on the original post (thanks to all the commenters!) and from several sites around the web.
Continue readingI have an old Brother HL-5250DN Laser Printer that’s been giving good service for years. Seems like forever since I replaced the toner cartridge (TN350 Black Toner Cartridge). But the other day, it simply stopped printing! It was out of toner, apparently. There must have been a “toner low” message, but I missed it.
Unfortunately it is quite unforgiving. Once it is below a certain point it simply stops functioning. Of course it was a most inconvenient moment for it to stop working.
All I could do was go look at Amazon for a new cartridge. Lo and behold, the customer reviewers there have come up with a quick fix to get the printer back up and running while you are waiting for the new cartridge to arrive.
Continue readingSometimes it’s helpful to have a quick reminder of how button events work within nested clips in ActionScript 2.
[ TRY DEMO ]
A button nested inside another button OR inside a MovieClip that has buttonEvents assigned to it will not work. (Button events include: onRollOver, onRollOut, onDragOver, onDragOut, onPress, onRelease and onReleaseOutside).
This is due to the way Flash captures events: the first parent instance with a button event handler assigned to it is the one that is listened to. None of its child objects will be listened for unless you use a workaround.
