Creating Enums from Tuple of String Literals

Description

It is as it sounds: this function will create something similar to an enum (in this case, an object with a null prototype) from a tuple of string literals.

Why?

Even though native enums have some convenient benefits, they can get a little "wordy" when you wish them to work like holders of string constants.

Simple "what's-my-ip" service

via Lambda@Edge

Usage

This will return the IPv4 or IPv6 address of the client making the GET request to the domain you specified when making the CloudFront distribution. If you add an Accept header with application/json present, it will return an json-parseable object like { "ip": "127.0.0.1" }, but if not specified or text/plain appears before application/json, it will default to text/plain and just return the IP address like 127.0.0.1 (following standard handling of Accept headers).

Implementation Notes

Activation

How to determine if it should be active/inactive

• AC Current Sensor
  • Gravity: Analog AC Current Sensor: Will be used to detect if the AC unit is currently "on" and active
    • Wiki
  • Gravity: I2C ADS1115 16-Bit ADC Module: Needed for converting analog signal from AC current sensor for Raspberry Pi

If you're using self-signed certificate for your web server on development, you might know the browser warning saying that your certificate isn't valid. If like me you had manually added an exception for this certificate error each time it showed up, this gist is for you.

Properly Configure OpenSSL with your DNS aliases

You'll have to create a self-signed certificate with a custom SubjectAltName.

1. Find your openssl config. find /usr/lib -name openssl.cnf

Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Lifecycle events are shown as the globally available outer events (all providers) and sub lifecycle events that are provider specific in the called order. Currently only the AWS provider is shown. If you have information about the other provider,

Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
