This is a presentation of the Worst Ideas Ever. But this is not just another "worst practices" presentation with random code samples. This presentation is about ideas that were specially engineered to be bad. This is not about bad coding practices, but about projects that never should have seen the light of day.
"Bad" is not the correct term for the software being presented. "Abominations" is a more accurate description. "Software perversions" might be even more accurate.
Do not try to understand why this software exists, but lay awake in bed at night afraid because it does. Jekyll and Hyde have nothing on this.
