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:

Deploying a Reflex Application to NixOS

In the following post I describe how a simple Haskell web application built on top of Reflex FRP can be deployed to a remote NixOS server. If a remote NixOS server is available using it for deployment can be cheaper alternative to commercial cloud providers in case the features of those (e.g. scaling, hosted services, availability guarantees, etc.) are not strictly required.

The sample Reflex application can be found on GitHub.

Our setting is as follows:

The application, consisting of a frontend and a backend, is built with Nix
The development system is a Mac (i.e., not x86_64-linux)

Not happy with Docker modifying your precious firewall rules?

Docker inserts iptables rules when it's started by default
buster uses nftables by default
let's make Docker use nftables instead
PROFIT

Prerequisites

Install Docker CE and nftables:

Yubikey + GPG + Github + Keybase

The following guide are steps that can be used to generate GPG keys on a YubiKey, use the gpg keys to sign github commits, and publish the public gpg key to Keybase.

Why is this a good idea?

Generating and storing GPG keys on a YubiKey allows the private key to be protected and ported between physical machines.
Signing git commits adds an extra layer of verification that code changes originated from an trusted source.
Using a YubiKey + touch-to-sign requires a physical presence to use the GPG signing key.
GitHub supports restricting commits to a repo to only those that are signed.
Putting a physical stamp on your code commits invokes a feeling of pride.
