I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.

defprotocol: defines an interface
deftype: create a bare-bones object which implements a protocol
defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

Reset the consumer offset for a topic (preview)

	;; http://mikehucka.postach.io/post/modifying-emacss-vc-diff-for-word-oriented-diffs
	;;
	;; Improvements:
	;; - Be smarter about adding --word-diff to `vc-git-diff-switches' and
	;; not clobbering any existing settings.
	;; - Use `defface' as the docstring for `make-face' recommends.
	;; - Base face defaults on `diff-added' and `diff-removed'.
	;; - Rename `vc-diff-deleted-face' to `vc-diff-removed-face' for
	;; consistency with existing face naming conventions.
