Folks tend to be curious about how much real projects cost to run on AWS, so here’s a real example with breakdowns by AWS service and feature.

This article walks through the AWS invoice for charges accrued in November 2016 by the TimerCheck.io API service which runs in the us-east-1 (Northern Virginia) region and uses the following AWS services:

  • API Gateway
  • AWS Lambda
  • DynamoDB
  • Route 53
  • CloudFront
  • SNS (Simple Notification Service)
  • CloudWatch Logs
  • CloudWatch Metrics
  • CloudTrail
  • S3
  • Network data transfer
  • CloudWatch Alarms

During this month, TimerCheck.io service processed over 2 million API requests. Every request ran an AWS Lambda function that read from and/or wrote to a DynamoDB table.

Urn: A Lisp implementation for Lua

Urn is a new language developed by SquidDev, and demhydraz. Urn is a Lisp dialect with a focus on minimalism which compiles to Lua.

What?

  • A minimal¹ Lisp implementation, with full support for compile time code execution and macros.
  • Support for Lua 5.1, 5.2 and 5.3. Should also work with LuaJIT.
  • Lisp-1 scoping rules (functions and data share the same namespace).
  • Influenced by a whole range of Lisp implementations, including Common Lisp and Clojure.
  • Produces standalone, optimised Lua files: no dependencies on a standard library.

¹: Minimalism is an implementation detail.
