How often are you asked what is your job? Most non-IT people will not be able to understand packaging, dependencies, rpms and whatnot. Hell, I even had trouble explaining what I do to my ex-schoolmates from university working in a traditional corporate environments. And they are software developers.
Was that just my problem? I don't think so. I had an epiphany while on a vacation few months back. I am almost sure the idea was not mine and it was just my subconsciousness that stole it from someone else. So what is my revelation? As you might have guessed from the title:
I am a software chef. I create recipes and prepare them.
I work in a restaurant, that we call Linux distribution. There are many restaurants, each having their own recipes, rules and so on. Some restaurants form "chains" where they share most of their recipes. In these cases there is usually one restaurant that creates most recipes (Debian is such a restaurant in its Linux ecosystem).
Each restaurant usually has hundreds of chefs, some of them specialize in few recipes (build scripts), some are more flexible. In my case I specialize in a type of recipes dealing with coffee (i.e. Java).
Every recipe starts with customer (user) ordering some meal they have heard about. I look up ingredients (upstream projects) the food is made of and start recreating recipe for our restaurant. Quite often the food is made of more recipes (dependencies) and I have to create those first. Sometimes these recipes are already being prepared by other chefs, so I just use their work for my final meal. However our ingredients can be slightly bit different from the original. For example we have cow milk, but no goat milk that was in original recipe. So I have to find a way to fix the recipe using spices (patches).
Creating recipes is only part of my job though. I also work with our suppliers of ingredients (upstream developers). Sometimes the ingredients are bad, or I have found a way to improve the ingredient so I contact the suppliers and we work together.
Third part of my job is improving cooking process (simplifying packaging). So sometimes I move some furniture around so that other chefs don't have so much between the fridge and other places. Or I create a new mixer (tools) that speeds up mixing of ingredients.
Final part of my job is to work in a VIP part of the restaurant (RHEL). Only some customers can go there, most meals are usually very similar to normal restaurant, but each meal is tasted (tested) before we give it to customers and if they don't like it they can complain and we bring them improved recipe.
I find this metaphor kind of works for most things to a surprising degree. For the record:
- Package maintainers - chefs
- QE/QA - tasters
- Security - bouncers
- Release engineering - waiters (sorry guys)
