A practical look at using tower as the middleware layer for Rust AWS Lambda functions, with examples that build up to a DynamoDB-backed per-IP rate limiter. It covers Service, Layer, stack ordering, short-circuiting, boxed async futures, and testing middleware without deploying a Lambda. Comments
If you work in IoT, environmental sensing, or data systems, forest soil monitoring is one of the most technically interesting problems you'll encounter. The system you're trying to measure is extraordinarily complex, the variables are deeply interdependent, and the consequences of getting it wrong — or not monitoring at all — are significant. The Problem Space: What You're Actually Measuring Soil

A hands-on dev review focused on i18n, date/number formatting, and non-ASCII edge cases. Why I Tested TestSprite for Locale Handling Specifically Most AI testing tools get reviewed for their core functionality — does it find bugs, does it write good test code, does it integrate with CI/CD. Those reviews exist. What I couldn't find was a focused review on how TestSprite handles locale-specific edge
There's about $400 of meat, milk, and miscellaneous condiments in my kitchen fridge at any given time. It runs 24/7, makes a quiet humming noise, and gives no indication when something's wrong until you open the door three days later and recoil. The freezer compartment is worse: a slow failure can defrost everything before you notice the puddle. I already had a TP-Link P110 smart plug on the fridg
One of the recurring challenges while building IoT systems is testing device communication, telemetry handling, MQTT flows, and event-driven architectures without constantly relying on physical hardware. To solve this problem, I recently started building a lightweight IoT Simulator CLI focused on helping developers simulate virtual devices directly from the terminal. The project is designed for de
