FAQ

Things people ask — or things I'd ask myself.

What is this site?

One guy's archive. A collection of what I've built, written, mixed or shared somewhere over the past twenty-five years — music, portfolio, texts, notes. I'm gradually pulling old tweets and Facebook posts back here too, so they don't stay lying around on someone else's servers.

Who's behind it is on the About page.

Where does the name Kerray come from?

It's Jarek — my name — backwards. It was coined in kindergarten and got its English spelling in 1993, when I sat down at the internet for the first time, at the Invex computer fair in Brno.

Why is some of it locked?

Some of the site is public. More personal parts sit behind a sign-in — things I'd rather not have loose on the internet. Signing in means I get to know your e-mail address; it stays on my server and goes nowhere.

If you want to see more, there's a questionnaire on your profile (work in progress). You don't have to fill it in — without it the basic gated content is exactly the same.

The long version is on the sign-in page and on your profile.

Can I delete my account?

There's no button for it yet. Write to kerray@kerray.cz and I'll delete you by hand.

Is that music actually yours?

Some of it, and it says so on each item. The DJ sets are other people's tracks in my selection and my mix — I've been picking music worth playing for over twenty-five years; psytrance, drum'n'bass a long time ago, more eclectic these days.

My own production is there too, just less of it than there should be — a lot of tracks stayed unfinished because the computer and every backup got stolen. And on the music page there's a group of things made with Suno, i.e. with AI — those are labelled separately.

Why isn't this on Facebook or Substack?

Because those are someone else's servers. Whatever I put there lives by their rules and disappears when it suits them. Here it sits on my machine, and you can carry it off over RSS.

Which is also why old things from those platforms keep showing up here — I'm pulling them back.

Can I write to you?

Sure — kerray@kerray.cz. Same address if you'd like me to play at your party.

What's that on your arm? What's that on your belly?

Type 1 diabetes. There's an insulin pump on my waist, a sensor on my arm reading glucose in my interstitial fluid, and a phone in between running AndroidAPS and xDrip+, deciding how much insulin the pump lets through at any moment.

It's an open-source closed loop — an artificial pancreas assembled from software people wrote themselves because the manufacturers cannot be held responsible for the software that can easily put you at risk.
