On JavaScript

A pinned tab can keep running Monday's JavaScript while a fresh page loads before its chunks finish uploading. A version marker helps with the first problem; publishing index.html last addresses the second.

Ad lazy loading is not just "load when visible". A useful implementation separates layout reservation, bid requests, rendering, and refresh policy, then tunes each step around real latency and viewability goals.

Updating aspect_rules_ts to 3.5.2 broke our pipeline with a missing BAZEL_BINDIR. The workaround depended on how Bazel combined action environments.

A runtime bidder from a floor-interception integration, reduced to one synthetic 1×1 response. Here is the bid shape, why the fields are there, and how to check that Prebid accepts it.

A pirate chatbot promises to draw a map. This April 2023 example connects its reply to an image generator through a custom draw tag.

A practical TypeScript pattern for chatbot message parsing: small predicates decide when a parser runs, parser functions emit domain events, and the dispatcher stops only when a command asks it to.

A small Promise bridge lets redux-form hand validation to a Redux Saga and receive field errors back. An integration example for older Redux applications.

A React class-component HOC that cancels superseded requests and checks request identity before updating state, so a late response cannot replace newer data.

Reducer composition is still the core Redux idea, even though modern Redux code usually starts with Redux Toolkit, configureStore, and createSlice.

Suppose a cart request succeeds and its event fires, but the badge stays wrong. Tracing the change shows where an event bus leaves timing and state for us to organise.
