Ubuntu: lightdm login manager does not display properly on boot

When I installed Ubuntu 11.10 and 12.04, I had the problem where the terminal would boot up until it said something about checking battery state, and then freeze. If I flipped to a different terminal, I could sudo launch lightdm - and then login on the first terminal. Obviously, this wasn’t my first choice in fixing this, though. (more…)

Theoretical Thoughts on Data Object Validation

One of the things I struggle with is the validation of data objects. I submit that there is such a thing as a dumb data object and a validation domain object.

Let me explain. (more…)

Using custom view scripts for Zend_Form in ZF1

To start out, I realize that a lot has changed in Zend Framework 2 regarding Zend_Form. I think there have been a number of interesting changes, but perhaps those changes weren’t explained that clearly either. But I digress. This piece is about Zend Framework 1.12.x Zend Form - and using view scripts for elements/the form. (more…)
