Organizing AWS microservices with Python, Serverless, and namespace packages

Our project began with a small ask: build a small Python back-end using AWS Lambda and API Gateway (with just a handful of endpoints to support a few pages) and use Serverless [https://serverless.com/] to manage the Cloud Formation setup. Not very involved, not much code, not even much configuration for the deploy. Next came authentication. In pursuing the joint dreams of DRTW ("don't reinvent the wheel") and WALCAP ("write as little code as possible"), we selected AWS Cognito over other opti

Securely Storing Data on iOS

Our mobile devices and the apps that run on them have a unique insight into our lives. We use them for communication, entertainment, shopping, photography, navigation, and myriad other purposes. Consequently, apps have access to a great deal of information about our preferences, our contacts, where we go, what we buy, and who we are. As app developers, we need to be cognizant of the information being handled by our apps and to safeguard it accordingly. The protection of sensitive information is

Compliance in Codebases - How to Use Clang LibASTMatchers for Compliance

The following article was created from a 2021 CppCon talk given by Jonah Jolley. One of our clients has a software product that must comply with federal regulations. For them, they must submit technical documents to a governing body. However, in their case, the codebase didn’t accurately reflect what was documented. This led to an unmitigated, unsafe condition. To solve this issue, we used Clang LibASTMatchers to check the codebase and ensure they were indeed compliant. Why Compliance in Cod
