I hired 2 fresh out of school junior devs to work with me on my old web app.
They were brilliant, knew a lot of things, and were motivated.
They started complaining about how the code was shit, the db was shit, there were no best practices, the technology was old, bug fixing was boring, no comments in code.

I felt bad, very bad during 3 years, because they were absolutely right. I tried to work with them through better coding practices, rewriting, documenting etc.

Now they both have left.
I'm alone maintaining and evolving the application.
And I start to come across the code THEY developed.

What a bunch of shit. SQL queries bringing down the server. Duplicate code, because they didn't want even read the old one. Useless comments.
Performance killing functions. Exceptions swallowed without mercy. I have to clean up they poop.

I feel somewhat better, though. The application is still growing and holding the ground after many years and generating at least 800K$ per year in revenues.

Maybe better, but sad. I really wanted to share the project with somebody else but I failed, and I'm left alone....
