# The recommended way to implement table-wide logic by defining methods on the dataset using dataset_module:

    class Post < Sequel::Model
      dataset_module do
        def posts_with_few_comments
          where{num_comments < 30}

A Guide to Encrypting Files with Mac OS X

This guide will demonstrate the steps required to encrypt and decrypt files using OpenSSL on Mac OS X. The working assumption is that by demonstrating how to encrypt a file with your own public key, you'll also be able to encrypt a file you plan to send to somebody else using their private key, though you may wish to use this approach to keep archived data safe from prying eyes.

Too Long, Didn't Read

Assuming you've already done the setup described later in this document, that id_rsa.pub.pcks8 is the public key you want to use, that id_rsa is the private key the recipient will use, and secret.txt is the data you want to transmit…

Encrypting

$ openssl rand 192 -out key

$ openssl aes-256-cbc -in secret.txt -out secret.txt.enc -pass file:key

Map	Action
<F1>	Causes Netrw to issue help
<cr>	Netrw will enter the directory or read the file
<del>	Netrw will attempt to remove the file/directory
-	Makes Netrw go up one directory
a	Toggles between normal display, hiding (suppress display of files matching g:netrw_list_hide) showing (display only files which match g:netrw_list_hide)
c	Make browsing directory the current directory
C	Setting the editing window
d	Make a directory

Общие упрощенные понятия. Возможно существуют способы задать другое поведение нежели данное упощенное.

Понятия

• producer - отправитель, программный код, который отправляет сообщение.
• consumer - получатель, программный код, который должен получить сообшение.
• exchange - обменник, функционал RabbitMQ, получает сообщение с заданными параметрами от отправителя и:
  • может сбросить(удалить) сообщение или вернуть отправителю (зависит от атрибутов сообщения),
  • может отправить сообщение в очередь,
  • может отправить сообщение в несколько очередей (сообщение будет скопировано для каждой очереди)
• queue - очередь, функционал RabbitMQ, хранит все сообщения и раздает их получателям.
• message - сообщение, содержит атрибуты необходимые RabbitMQ, а также данные для передачи от отправителя к получателю
