Warning! This is a #mimimi blog post.
Jeez! Some things are so difficult to live with, even for a short time.
Please, I don’t care about the size of your company, but please, you need have a scm to your developers. I don’t care if you are a manager that thinks that your team are great working together and you don’t need a scm system, you need, and yes, you are an idiot for thinking that you don’t. I almost can hear your developers yelling: “I’ll use the file b, no one put a hand on it!” with pain in theirs faces.
Your developers need a test environment to work on, they need a test database, and a scm system and code documentation, at least. They are humans, you know, and humans can screw up things easily.
You should be very worried if your developers work on production. No, you should be shame. You should be burning in hell too.
