ok2cry - end to end cryptography for the API ecosystem.

The following story explains the business need that gave birth to ok2cry. It shows why the need will continue to increase.

Composing products: to innovate in business and to delight customers

A fintech company wanted to offer credit cards to its customers over the loan product that they offered. In the modern manner, they outsourced the credit card management to another company. This kept them out of any regulatory controls which keeps costs and risk to a minimum. It offered an efficient way to quickly launch this new option and make their product more valuable and desirable to customers.

High security standards

The fintech company were using state-of-the-art cloud services to run their operations and manage customer access using Multi-Factor Authentication (MFA).

Introduction

A conversation started at the Heart of Clojure conference in Belgium on Friday August 2nd 2019.

The group represented project owners from Maria.Cloud, Next.Journal, Klipse and Replete-Web. The projects make significant use of self-hosted CLJS.

This is a proposal to have a service that generates and caches JS files for a specific CLJS dependency (name & version).

Background

The ClojureScript compiler generates JS files for each of an apps stated CLJS dependencies. The runtime environment then loads each of the needed JS files to satisfy the dependency at runtime.

The person, one Mr Cuntis Yarvin, at the centre of the #lamdaconf debacle performed an Ask Me Anything on Reddit. One of his defenders on Twitter referenced this response from the AMA as proof that he was not racist.

I appreciate that giving more commentary space to this situation provides the oxygen that our protagonist craves. On the other hand I feel like this is sufficiently important to our community to stand up and defend those people that this person seeks to diminish and damage.

So, with that and a deep breath, let's take this response bit by bit and see whether it works out as a defence by the protagonist as evidence of his lack of racism.

Amusingly, my "one offensive comment" was actually me repeating something my wife (not at all a 'shitlady') learned in her MFA program at SF State (not at all a Hitler Youth academy). (This is the observati
