The basics

This is a collection of basic "recipes", many using twurl (the Swiss Army Knife for the Twitter API!) and jq to query the Twitter API and format the results. Also, some scripts to test or automate common actions.

# This playbook assumes the WebSphere MQ file provided by IBM has already been
# downloaded to a specific directory (target.wd) on the server. 
#
# ${target.wd} is a variable representing the working directory on the target
# server the MQ client will be installed.
#
# Note: Although this playbook is designed to be able to be run independently,
# it is in fact part of a longer playbook and therefore may have some other
# unexpected dependencies not reflected here.

/**
 * Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
 * in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
 * the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
