Our DynamoDB scheduler writes recurring rules as rows 90 days ahead, fires them with a leased 300-second sweep, and claims each in one transaction. Plus the 6 to 24 hour gap where a row never fires.
Why an operator's already-open tab is the hardest client your platform has — and what it costs to keep it working. An operator opens a console screen, starts a support case, and types a note into a dialog. Two minutes later we deploy. Their next interaction behaves differently
An admin console usually starts with a straightforward setup. A page needs data, so it calls an API. Another page needs authentication, so someone adds a token. A third page needs error handling, so its developer copies a helper from somewhere else. It works, and for a while, nobody has
A bowl that never stops talking Every EverBowl in a customer's kitchen is a small sensor station: a load cell weighing food and water, a temperature probe, a microphone and a camera, all reporting to the cloud around the clock. That stream lands in two tables in Amazon
Every admin console starts with the same page: a list of all users. A table, a search box, maybe a filter for "signed up this week." In most stacks it's a one-line query and an afternoon of work. When we sat down to build that
Packaging structure that builds first-impression trust. The first interaction of a product with a customer doesn't begin when it's switched on. It begins when the package arrives, gets opened, and shows how the product was protected and presented. That moment sets two expectations: the product
The problem We needed two cameras on a TI AM62A7-Q1, and the SoC gives us exactly one MIPI CSI-2 receiver. It is a 4-lane port, and the cameras we picked are IMX708 modules in the Raspberry Pi Camera Module 3 class, each running 2 data lanes. The
Three patterns for a reliable cloud-to-device command path: derive timeouts on read, use a conditional write as your idempotency primitive, and never trust the broker to tell you which environment a message belongs to.
Inside a pet feeding station, two sensor modules share one CAN FD bus with the compute module that owns the uplink. The camera module sends images and thermal frames. The audio module records what the pet sounds like while it eats. The same event triggers both, and the bus cannot
Observation: we kept the document and deleted the code Our old admin console had grown for years. It had its own server and its own copy of every table name, and it drifted from the backend every time a field changed. The rebuild replaced it with a thin shell that
