Minor drawback with Memcached

Today, we had an XML process change so invalid XML was being returned (or changed invalid XML, because it's always invalid, but we had a fix for the prior version). Instead of just affecting us while the bad data was being returned, it actually lasted a little while longer. Why? Because we use memcached to store the result, lessening the load on our inventory management system.

While it isn't normally an issue (most people don't deal with this oddball system), if we were storing those results longer than we had been, this could have been a huge issue. It was rendering product pages non-functional, which isn't a good thing.

As a result of this, we're going to start doing more error checking and trapping. Oh what fun it is to deal with systems that don't care about being valid in the slightest and having Perl modules that require it.

Yii multiple select dropdownlist with default values

So I was coding a form in Yii, and came across a situation where I had a value of 0111110 (no, yes, yes, yes, yes, yes, no) that I needed to pre-populate values in a multiple select drop down. This didn't seem like it should be that hard, but the Yii documentation lacked a bit there. The first step was to split out the string. $optionValues = str_split($model->variable); Now, we create a blank array to hold our options. $options = array(); Then, we go through those options and set selected on the ones that need selected. foreach ($optionValues as $optionKey=>$optionVal) {      if ($optionVal) {         $options[$optionKey] = array('selected' => 'selected');     } } Now, we render the drop down list. echo $form->dropDownList($model, 'variable', array('0' => 'Zero', '1' => 'One','2'=>'Two','3' => 'Three', '4' => 'Four', '5' =&g

May 2021 updates

 Lots of work has been done since I last posted. Everything feels different, and gigs have been scheduled. It's time to get ready to play live again. Maiden Voyage We're playing a primarily hispanic audience show in a few weeks. New bass player is continuing to learn the songs, new guitar player keeps impressing me with his resolve, and as a band we feel ready for a couple hours of Maiden music. We're also playing a benefit for our lost blood brother in July, where we'll be playing the set list we did at our final show with him. Somehow, Live After Death seems fitting for that show, so that's what we're performing. We also have a special "something" planned for the first song which should hit everyone right in the feels. Pop Band We're currently using the name Hard Candy for this one. We're going to be playing a couple of benefit shows to get things started on stage. One is for our former drummer Dan and also the one with Maiden Voyage in Bill&

Been getting busy

It's been a while since I posted, so I thought it was time for an update. Maiden Voyage is starting to get busy. This summer saw quite a few shows and several benefits with us performing. We had our first show with us providing sound, which meant I had to buy a trailer. That was going to become necessary anyway just to continue moving our light show around, so it just worked out well. We played in Lincoln for the first time. Nothing earth shattering about playing another town about 60 miles from where we're based, but after that one show we immediately booked 2 more in Lincoln with minimal effort. Guess that first show is the most important one like they say... only one chance for that first impression. Speaking of 2 more shows with minimal effort, that's how most of our shows are happening now. We're not even looking for shows all that hard and are starting to have booking agencies and show promoters contacting us about being a headliner for some bands they'r
