If you use Amazon AWS for nearly anything, then you are probably familiar with KMS, the Amazon Key Management Service.

KMS is a service which allows API-level access to cryptographic primitives without the expense and complexity of a full-fledged HSM or CloudHSM implementation. There are trade-offs in that the key material does reside on servers rather than tamper-proof devices, but these risks should be acceptable to a wide range of customers based on the care Amazon has put into the product. You should perform your own diligence on whether KMS is appropriate for your environment. If the security profile is not adequate, you should consider a stronger product such as CloudHSM or managing your own HSM solutions.

The goal here is to provide some introductory code on how to perform envelope encrypt a message using the AWS KMS API.

KMS allows you to encrypt messages of up to 4kb in size directly using the encrypt()/decrypt() API. To exceed these limitations, you must use a technique called "envelope encryptio

First, check your current config (example output in homebrew.mxcl.postgresql.plist.xml lower down in this gist):

cat ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Most importantly, note the -D /usr/local/var/postgres argument.

Second, shut down your current PostgreSQL.

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Sends Cloudwatch Event notifications to Slack

What is this?

AWS have released a new featue called CloudWatch Events, which lets you configure events fired by cloudwatch and direct them to SNS, Lambda functions, etc. Here's the blog post

Create a local VM of Alpine Linux, eg: https://gist.github.com/kennwhite/959d47a77070d365ad60

On your workstation open a terminal and create a new ssh keypair:

ssh-keygen -t rsa -b 4096 -C "[email protected]"
- Set a meaningful keypair base file name when prompted, eg: alpine-test

The case for Rollup and ES modules in frontend code

TLDR: Rollup and ES modules give us:

smaller bundles due to tree-shaking and scope-hoisting, and
faster runtime perf than CommonJS, by avoiding runtime module resolution

Suppose you're opening an issue and there's a lot noisey logs that may be useful.

Rather than wrecking readability, wrap it in a <details> tag!
