Dispatches from the work in progress
Most LLM personalisation demos look great. You pass in a profile, ask the model to "tailor this", and the first output reads as if someone who knows the user wrote it. Then you run it across a few dozen real profiles, read every result, and the picture changes.
Segment labeling means marking each stretch of a recording with its own start time, end time and sound, instead of giving the whole clip one tag. In our labeling tool, a reviewer picks from 11 labels (10 sounds plus Unknown), drags a region on the waveform, and the server saves
A hardware debounce circuit for a high-vibration environment needs a measured time window for both edges, not just a capacitor across the switch. In our reference input, a 100 kΩ pull-up and a 100 nF capacitor feeding a Schmitt-trigger input delay the release by 11.1 ms, and a 10
Great design decisions travel faster when everyone can picture them. A fastener choice, a foam type or a surface finish is second nature to engineers, but to teammates in design, operations or marketing the same choice can sound like a list of specialist terms. While taking EverBowl™ through late-stage engineering,
An audio codec on a battery wearable should be fully powered down whenever nothing is recording, and woken only when there is something worth hearing. On our dog collar, the codec, its microphone bias supply, its crystal oscillator and the MCU's audio interface are all off between recordings.
We built our content planner to extract pictures and embedded videos directly from Excel files in the browser. Google Drive links follow a different path: a background worker downloads each file and streams it into storage in 8 MiB parts, without loading the entire file into memory, even when the
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 from
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 page
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 should
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 first idea everyone
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
