I have been playing around with Tiltview for the past couple of days which is an addition to a WordPress plugin called NextGen FlashViewer. Let me start by saying that even though I had a couple problems when starting out the combination of NextGen Gallery, NextGen Flashviewer, and Tiltview is one of the coolest combinations I have seen. It actually is fairly easy to get going and surprisingly when configured properly is not a huge CPU and memory hog. If you have configuration errors as mentioned below it can clearly be a PC resource monster. You definitely can see it taking up some memory but most client PC’s have plenty to handle Tiltview style applications these days. If you have something configured incorrectly as I mention below it wil easily crash browsers and possibly lock up the entire PC. My 1.8 GHz Windows XP laptop with 2GB of RAM was on its knees begging for mercy during troubleshooting the issues I explain below.

If you want to see the actual active lines from a configuration file in Linux you can exclude any lines with comments by issuing the below command.

shell# cat /etc/postfix/main.cf | grep -v “# *”

If you also want to exclude the blank lines from the file use this command.

shell# cat /etc/postfix/main.cf | grep -v “# *” | grep -v “^$”

Sometimes that does not catch every line so add one more grep to exclude the lines that does not catch like this.

shell#cat /etc/postfix/main.cf | grep -v “# *” | grep -v “^$” | grep -v “  “

I was a bit furstrated last night when I tried to install the flash templates from paulvanroekel.nl because the installer was telling me it was completed yet I could not find the templatebs. After trying to figure it out for a bit I went back to the site and noticed I had missed the install instructions at the top right of the download page. I seem to like to jump into things and forget to read instructions a lot!

It turns out the installer is for Picasa 2.x and Google has decided to change folder locations in the Picasa 3.x versions. Now instead of being on your primary drive under Program Files >> Picasa the application is now located in C:\Program Files >> Google >> Picasa3. So if you end up running the installer you can just copy the files from C:\Program Files\Picasa2\web\templates to C:\Program Files\Google\Picasa3\web\templates and the new templates will show next time you export a folder or a single photo to HTML via the Picasa interface.

The collection of templates includes 19 in all including simpleviewer, tiltviewer, imageflow, highslide, lightbox, thickbox, and more. All of them are cool in there own way and can be viewed here.

There are numerous reasons it is beneficial to have your own gem server including controlling the versions of various gems deployed to all of your servers. Below is a brief explanation of how to install a gem server on your local network.

When initially attempting to install the data_fabric gem I was getting the below error.

Error:
gem install data_fabric
ERROR: Error installing data_fabric:
data_fabric requires RubyGems version = 1.2

It is possible to get this error if you have upgraded to rubygems 1.3 and you are attempting to install data_fabric (version: 1.0.1 or below). If you have access to the gem server you are installing from them just update the data_faric gem on that server but if not then add the rubyforge gem repository as follows.

gem install –source http://gems.rubyforge.org/ data_fabric -v 1.0.2

That should do the trick.
