AI agents can now scan an entire open-source codebase for exploitable vulnerabilities in hours. Frontier models carry the complete library of known bug classes in their weights. So you can simply point an AI agent at a codebase and tell it to find zero-days. This isn't theoretical. Willy Tarreau, the HAProxy lead developer, reports that security bug reports have jumped from 2–3 per week to 5–10 per day. Greg Kroah-Hartman, the Linux kernel maintainer, described what happened: "Months ago, we...

Lambda Durable Functions makes it easy to implement business workflows using plain Lambda functions. Besides the intended use cases, they also let us implement ETL jobs without needing recursions or Step Functions. Many long-running ETL jobs have a time-consuming, sequential steps that cannot be easily parallelised. For example: Fetching data from shared databases/APIs with throughput limits. When data needs to be processed sequentially. Historically, Lambda was not a good fit for these...

Step Functions is often used to poll long-running processes, e.g. when starting a new data migration task with Amazon Database Migration. There's usually a Wait -> Poll -> Choice loop that runs until the task is complete (or failed), like the one below. Polling is inefficient and can add unnecessary cost as standard workflows are charged based on the number of state transitions. There is an event-driven alternative to this approach. Here's the high level approach: To start the data migration,...
