I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

float map(float value, float min1, float max1, float min2, float max2) {
  return min2 + (value - min1) * (max2 - min2) / (max1 - min1);
}

Touchscreen Calibration in Debian9

Unfortunately [xinput-calibrator][1] does not work at all for calibrating a touchscreen in Debian9. This is apparently because X server now uses libinput to handle input devices instead of evdev. I spent huge amount of trying to fiddling with xinput-calibrator and 99-calibration.conf files until I finely found this [issue][2] on GitHub that gave me some hints as how to proceed. This is mostly for my own reference, but I hope it might also help others in the same situation.

Encoding to Hap from the command line using FFmpeg

For users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.

1. If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.

   You can check that your version of FFmpeg can encode Hap using

   ffmpeg -encoders | grep hap
