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:

NΛNO Emacs font stack

Default font: Roboto Mono , 14pt, Light
Italic font: Victor Mono , 14pt, Semilight
Bold font: Roboto Mono , 14pt, Regular
Unicode font: Inconsolata , 16pt, Light
Icon font: Roboto Mono Nerd , 12pt, Light

Text excerpt using a gorgeous and true italic font (Victor Mono), chosen to really stand out from the default font (Roboto Mono).

A sensible NixOS Xfce Configuration

NixOS provides good support for the Xfce desktop environment out-of-the-box, but the defaults are minimal. The files in this Gist provide a more complete experience, including a suite of basic software and plugins as well as an optional home-manager configuration for theming.

The key additions to the default Xfce provided by NixOS are:

Complete bluetooth / audio support with panel indicators and apps
LightDM with theme
Extra Xfce apps for calendaring, disk partitioning, etc.
Various quality-of-life improving non-essentials

	# This gist illustrates how to create and execute a payment with Paypal using their REST API.
	# For additional informations, check the documentation: https://developer.paypal.com/docs/api/

	# Note 1: I assume that you have already created a developer account for Paypal and an application.
	# To test that your code is working, use the sandbox accounts.
