Deprecated Notice

This script, originally created on April 29, 2015, addressed a different behavior of LibreOffice installation on macOS at that time. However, it is now outdated and no longer relevant. Please refer to the latest comments for updated information, as much has changed over the past 8–9 years.

Quick Start

Converting a Word Document to Markdown in One Move

The Problem

A lot of important government documents are created and saved in Microsoft Word (*.docx). But Microsoft Word is a proprietary format, and it's not really useful for presenting documents on the web. So, I wanted to find a way to convert a .docx file into markdown.

Installing Pandoc

On a mac you can use homebrew by running the command brew install pandoc.

The Solution

Upload a file with $.ajax to AWS S3 with a pre-signed url

When you read about how to create and consume a pre-signed url on this guide, everything is really easy. You get your Postman and it works like a charm in the first run.

Then you open your browser, try your usual $.ajax() and send your PUT operation, and you hit the cold iced wall of AWS error message, a simple <Code>SignatureDoesNotMatch</Code> that will steal hours from your productivity.

So here I come to save you and give you a free working example of how to upload a file directly to AWS S3 from your browser. You are wellcome :).

Building a Maintainable, Agile Architecture for Realtime, Transactional Apps

A maintainable application architecture requires that the UI only contain the rendering logic and execute queries and mutations against the underlying data model on the server. A maintainable architecture must not contain any logic for composing "app state" on the client as that would necessarily embed business logic in the client. App state should be persisted to the database and the client projection of it should be composed in the mid tier, and refreshed as mutations occur on the server (and after network interruption) for a highly interactive, realtime UX.

With GraphQL we are able to define an easy-to-change application-level data schema on the server that captures the types and relationships in our data, and wiring it to data sources via resolvers that leverage our db's own query language (or data-oriented, uniform service APIs) to resolve client-specified "queries" and "mutations" against the schema.

We use GraphQL to dyn

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

CLJS in AWS Lambda Quick Start

Setup

First, a few dependencies:

Leiningen: https://leiningen.org/
Node.js & NPM: https://nodejs.org/
Serverless: https://serverless.com/
An active AWS account: https://aws.amazon.com/

Usage

Start up the new cljs.main with Node:

clj -Sdeps '{:deps {org.clojurescript {:git/url "https://github.com/clojure/clojurescript" :sha "3f4084efcb5cd92cceb8ca30765144691d8cfd7e"}}}' -m cljs.main -re node

The above works by specifying ClojureScript as a "git dep" and you can ensure that you are running the very latest by replacing the :sha value with the latest commit SHA at https://github.com/clojure/clojurescript.

	Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.

	First off, bundle.
	==================

	1. cd to the project directory
	2. Start the react-native packager if not started
	3. Download the bundle to the asset folder:
	curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"

	(ns om.next.spec
	(:require [cljs.spec :as s]))

	(s/def ::ident (s/and vector? (s/cat :ident keyword? :value #(not (coll? %)))))
	(s/def ::join-key (s/or :prop keyword? :ident ::ident))
	(s/def ::join (s/and (s/map-of ::join-key ::query) #(= (count %) 1)))
	(s/def ::union (s/and (s/map-of keyword? ::query) #(> (count %) 1)))

	(s/def ::param-expr
	(s/cat :query-expr ::query-expr

	'use strict';
	exports.handler = (event, context, callback) => {

	// Get request and request headers
	const request = event.Records[0].cf.request;
	const headers = request.headers;

	// Configure authentication
	const authUser = 'user';
	const authPass = 'pass';
