Phil Sturgeon has a post with several "developer fallacies" of 2014, a tongue-in-cheek list of things that some people were sharing as facts that just weren't.

Let’s take a look back at some of the silly, shortsighted or patently false things people have been saying around the PHP community, and the development community in general, starting from January 1st 2014 and going through in rough chronological order.

Included in his list are things like:

• No programmers ever get hired by recruiters
• Framework agnostic code takes drastically longer to develop and release than framework specific code
• Micro-services should probably always be .jar files instead
• PHP 7.0 is a better name than PHP 6.0 because 7 is lucky in China
• PHPNG is Zend’s response to HHVM and they are the same thing
• Maintaining CodeIgniter - when actively used by thousands of people - is a waste of time

Of course, all of these (and the rest of the list) are false and several of them are just based on things spread word of mouth or misinterpreted when shared from one person to another.
