Anyone Can Cook: Writing Good Cookbooks as a Beginner

Abstract

Learning to write high-quality Chef cookbooks can be a daunting prospect. There are few resources and little documentation. Let's dive in to the best practices to build usable, maintainable, and delightful Chef cookbooks. We'll cover the structure of great cookbooks for new and experienced Chefs alike.

Behind Closed Doors: Managing Passwords in a Dangerous World

Description

A modern application has a lot of passwords and keys floating around. Encryptions keys, database passwords, and API credentials; often typed in to text files and forgotten. Fortunately a new wave of tools are emerging to help manage, update, and audit these secrets. Come learn how to avoid being the next TechCrunch headline.

Abstract

Secrets come in many forms, passwords, keys, tokens. All crucial for the operation of an application, but each dangerous in its own way. In the past, many of us have pasted those secrets in to a text file and moved on, but in a world of config automation and ephemeral microservices these patterns are leaving our data at greater risk than ever before.

Okay, so lets rewind a bit. Roundup is a brand name used by Monsanto for a type of herbicide called "glyphosphate" While it was under patent protection for 20 years, those patents all expired back in 2000 so now many companies market similar herbicides. These products are used by farmers to kill off smaller plants like grasses and bacteria that spread in the wild and would use nutrients in the soil that the farmer would rather be absorbed by their crops. It does this by blocking the creation of a few key proteins needed by all cells. This doesn't affect insects for the most part as animals don't make these proteins ourselves, we have to eat them ("essential amino acids"). But in plants, it kills them by denying them these required proteins.

Enter "Roundup Ready Soybeans" (and others, soybeans were the first though). They took genes from a few sources (a specific bacterium, a virus that infects cauliflowers, and a petunia flower) and combined to create a new method to synthesize those essential proteins, spec
