Ask HN: What is your development setup?

I was wondering what do folks use here these days. I am interested in knowing almost everything (from desks, chairs to software) that you use for building your products and achieving your goals. That is, your entire setup.

Also, if you could change one thing, what might that be?

Examples of some areas of input -

* PC/Laptop specs * OS * Major languages * Source version control * Editor(s) (with Plugins) * Servers, if any etc.
