Hello everyone!

I've recently got an idea for a Database as a Service I'd like to create. The only issue is - I don't know how to create or host a database!

I've only ever used Mongoose/mLab with Javascript, and a minimal amount of Postgres with Python.

If I'm looking to create a database that will, eventually, be able to store images, songs, and videos, where should I start my homework?

I can create the backend and the frontend with no issue - just stuck on this part here. If it's of any relevance, I most frequently use the MERN stack.

I might soon be part of an internet startup. We're talking with a relative about setting up a consultancy & business news service on a certain sector, and I've generated a part of the idea and accepted to take on the technical/editorial side for a while (I've almost a year til when I start my master's, and will probably work up until when I start my thesis; so almost two years). If things work out, this might be a dream job (except academia) for me, and even very lucrative. But I'm fairly n00b in this space, both business and professional work, though I have the technical skills. Thus I'm seeking general advice on

• how to organise this thing: how to make sure we communicate well on dates and plans and how to make educated guesses when setting up an agenda

• how much will it cost: we'll start with making a database and running a sector-specific blog/news site as publicity (though I'll make sure the content is quite decent, not just a showpiece), but then later we'll introduce a tangential online service and a mobile app leveraging that crowd

• working with non-techies: I'll be the only techie in this startup and I need to help people with gathering, storing, organising and utilising historical data with certain variables, ensuring they keep an accurate record and can make quality queries easily; the 3 people apart from me will be non technical

I think quite a bit of you here have been involved in this sort of scenario, so maybe you could have some advice for me. I'd appreciate anything, examples of approaches, links to tools, what not, anything you think could be useful. Thanks a lot in advance!

It's a dry, windy day. I had my left hand stationary on my cat's back and was petting him with my right hand. I noticed when I removed my right hand from contact with his fur, I got tiny shocks in the middle finger of my left hand, but only when removing my right hand and only in my left middle finger. (He didn't seem to notice any shocks.)

Why is this very specific type of electric shock occurring?
