It's not that Roc only supports base-10 arithmetic. It also supports the typical base-2 floating-point numbers, because in many situations the performance benefits are absolutely worth the cost of precision loss. What sets Roc apart is its choice of default; when you write decimal literals like 0.1 or 0.2 in Roc, by default they're represented by a 128-bit fixed-point base-10 number that never loses precision, making it reasonable to use for calculations involving money.

In Roc, floats are opt-in rather than opt-out.

From the STOMP homepage:

What is it?

STOMP is the Simple (or Streaming) Text Orientated Messaging Protocol.

STOMP provides an interoperable wire format so that STOMP clients can communicate with any STOMP message broker to provide easy and widespread messaging interoperability among many languages, platforms and brokers.

Simple Design

STOMP is a very simple and easy to implement protocol, coming from the HTTP school of design; the server side may be hard to implement well, but it is very easy to write a client to get yourself connected. For example you can use Telnet to login to any STOMP broker and interact with it!

From John's blog post:

In the interest of learning Factor, I thought I would write a bit about parsing the STOMP protocol, and then about how to implement a client library using connection-oriented networking, interacting with it using mailboxes, and then building a command-line interface using the command-loop vocabulary.

There are many STOMP servers and clients available in different languages. I tried a few and decided that Apache ActiveMQ was one of the most convenient to setup and reliable to work with, but others are available as well.

John B's blog post calls it:

. . . a pretty neat hour long introduction going over a lot of features that users new to the language might be interested in.

The video creator's description:

This is an introductory tutorial for a stack-based (concatenative) programming language Factor. It covers some basic language constructs and a few features of the interactive development environment that is shipped with Factor.

I've re-shot my two prior recordings combining everything into a single video.
