Dumping Datomic data into a local (free) transactor

Create a database dump from the server running the transactor

bin/datomic backup-db "datomic:ddb://us-east-1/rest/of/url?aws_access_key_id=<ACCESS_KEY_ID>&aws_secret_key=<SECRET_KEY>" file:/home/ian/datomic-backup-`date +"%Y%d%m"`

Transfer the dump to your local machine

A Starting Point for using Emacs & Evil-mode

(I wrote a bit about why Emacs and Vim on my blog and thought it might be nice to give some starting point for people that want to try it.)

If you just want to play around with Emacs & Evil mode do the following:

1. mkdir ~/.emacs.d/
2. copy init.el into ~/.emacs.d/
3. Download Emacs from http://emacsformacosx.com

Emacs packages, features, files, layers, extensions, auto-loading, require, provide, use-package… All these terms getting you confused? Let’s clear up a few things.

Files

Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.

One major problem is to ensure that all the correct files are loaded, and in the

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))
