macOS Catalina (10.15+) Notarization Requirement for Go
View notarize.md

macOS 10.15 Catalina requires binaries are notarized to run without annoying additional steps. See the issue here: https://github.com/hashicorp/terraform/issues/23033

These are steps to notarize a direct binary. This does not cover stapling, installers (pkg), etc. This is primarily useful for static binary developers such as Go developers.

Manual Steps

Apple Developer Account

You first need an Apple Developer Account ($99/year). You need to accept all the agreements and stuff.

Radix tree and validation in TLA+
View RadixTrees.tla
This module contains operations for working with radix trees. A radix tree
is a data structure for efficient storage and lookup of values that often
share prefixes, typically used with strings.
A common question when I show this to people is: how do I add to the tree?
delete? update? For these, grab the Range of the tree, use set logic to
add/remove any elements, and construct a new tree with RadixTree.
For educational purposes, I've heavily commented all the operations. I
recommend using the constant expression evaluator to try the building blocks

THIS WAS ORIGINALLY POSTED ON MY TUMBLR ON FEB 25, 2011. I forgot I had a Tumblr account. I recently logged in (in light of the acquisition by Automattic), found some old posts, and I'm republishing them exactly as they were with zero modifications.


CloudFormation: The Big Picture

Amazon announced CloudFormation to the public yesterday, and while the general opinion I could glean from various sources shows that people are excited about this new technology, many are still unsure what it is and how it fits into their current cloud workflow. I feel as though I have a firm grasp on CloudFormation and will attempt to answer some questions here.

Note: I'm definitely not a representative of Amazon in any way, and anything here is simply my educated opinion on the matter.
