Day 45

Today, I:

• watched System Design Interview: Design Dropbox or Google Drive w/ a Ex-Meta Staff Engineer — presigned-URL uploads straight to blob storage, chunking large files for resumable uploads and dedup, and syncing changes across devices
• watched Kafka vs RabbitMQ — log vs queue as the root distinction, consumer groups vs acked push delivery, and when to reach for streams/replay versus a task queue
• at work, used Datadog's new Bits AI agent — which lets you program an LLM agent to answer questions about your logs, metrics, and traces — to generate a daily report analyzing the previous day's data across our monitored services, delivered every morning at 9:30 as another read on application health on top of our existing monitors and dashboards
