Parse public AIP (Aeronautical Information Publication) and convert the data to either AIXM (Aeronautical Information Exchange Model) or OFMX (Open FlightMaps eXchange).

Calculations for AIRAC (Aeronautical Information Regulation And Control) cycles.

Build XML descriptions of aeronautical infrastructure either as AIXM 4.5 (Aeronautical Information Exchange Model) or OFMX 1 (Open FlightMaps eXchange).

Credentials like passwords, access tokens and other secrets are often passed to sites each by it's own ENV variable. This is both uncool, non-atomic and therefore unreliable. Use this plugin to store your credentials in encrypted YAML files which you can safely commit to your source code repository. In order to use all of them in Bridgetown, you have to set or pass exactly one ENV variable holding the key to decrypt.

Manage and deploy secrets (access keys, API tokens etc) in encrypted files which can safely be committed to the code repository. To decrypt and and use them, only one environment variable containing the corresponding key is required. While similar to ActiveSupport::EncryptedConfiguration, this lightweight implementation introduces as few dependencies as necessary.

Simple Minitest helper to replace values such as an instance variable of an object or an environment variable for the duration of a block or a group of tests. This comes in very handy when you have to derive from default configuration in order to test some aspects of your code.

Parser for NOTAM (Notice to Air Missions) messages in Ruby.

OGN (glidernet.org) broadcasts aircraft positions as APRS/APRS-IS messages. This gem hooks into this stream of data and provides the necessary classes to parse the raw message strings into meaningful objects.

Somewhat more radical filters designed to decimate malicious requests during a denial-of-service (DoS) attack by chopping their connection well before your Rack app wastes any significant resources on them – ouch! The filters have been proven to work against certain DoS attacks, however, they might also block IPs behind proxies or VPNs. Make sure you have understood how the filters are triggered and consider this middleware a last resort only to be enabled during an attack.

Just the bare minimum of what's needed to create bi-directional chat bots using Roda as backend, sucker_punch and Clockwork for async and timed jobs.
