# Basic implementation of a websocket connector for Slack using the slack-ruby-client gem
# 
# Run this rake task in a virtual container that is set to automatically restart on failure; this
# will help deal with disconnects from Slack since socket URLs are temporary.

#
# This rake task can be called in multiple virtual containers to help with resilliancy and rolling restarts

I've found a bug that is specific to the following scenario:

• Using MySQL
• Using a longblob column type
• Using a serialized attribute
• Using paper_trail gem
• Serialized field contains unicode character

Under those conditions, after saving changes to the serialized field, record#changed? still reports true, and record#changes contains an entry for the serialized field where both the before and after elements are identical. Calling record#reload clears the changes and loads the record with the changed value. If paper_trail is removed from the scenario, the ActiveModel attribute mutation tracking works as expected.

Doubly Linked List implementation in Ruby

Setup

• Install Ruby ~> 2.6
• gem install rspec
• Open an IRB session with irb -r ./linked_list.rb

list = LinkedList.new

A ruby module to assist in capturing stdout/stderr from a detached thread in jRuby

1. create some temp files (but not Tempfiles since they would be GC'd too quickly)
2. append standard file descriptor redirects to the commands that we'll run in the detached spawned process, i.e. 1>>stdout_tempfile_path 2>>stderr_tempfile_path
3. tack on a final command that will trigger copying the files to S3 regardless of exit status of original commands, i.e. {original commands with io redirection &&'d together}; bundle exec rake cleanup_task
4. cleanup other io redirection temp files older than some threshold

Example usage:

i18n for Panini

Requirements

Other than the default Panini pieces, you will also need to make sure that lodash is included as a devDependencies in your package.json

Usage

Tag a section of text as translatable. The section will be replaced with a set of if/elseif/else Merge Tags for each translation provided, otherwise only the wrapped content is displayed.
