Read Retry-After and wait, instead of retrying into a wall — a client that obeys sent 43 requests where a blind one sent 55,930, and both finished in the same three seconds. Then publish your own limit as a token bucket, per customer.
AI & Data
Prompting for JSON gets you JSON most of the time, which is the problem. Constrain the output to a schema, validate it before you trust it, let the model assign among values you supplied, and send failures to a human rather than swallowing them.
AI & Data
Most mail can be triaged on metadata alone and never reaches a model. What is left gets redacted before it is sent, checked with a residual scan, and stored as a derived fact rather than a message body.
Integration
Most teams reach for a stream and need a queue. Cron loses the window it missed and runs itself twice; a queue fixes both in one clause; a stream is only worth it when several consumers need the same events, or you need to replay them.
Integration
Store every step's input, output and error as rows the customer is allowed to read. It is the difference between "it failed, please send a screenshot" and the customer finding the 422 themselves.
Infrastructure
Ignore the cost numbers. Put your finger on the estimated rows and the actual rows of every node, and find the first place they disagree by more than an order of magnitude. That node is your bug, and everything above it is a consequence.
Infrastructure
A backup nobody has restored is a hypothesis. Here is a restore drill that runs in under four seconds against a scratch container, compares row counts against the source, and fails loudly when the dump is quietly incomplete.
Infrastructure
GPTBot, ClaudeBot and PerplexityBot do not run JavaScript. A client-rendered SPA serves them an empty div, so nothing you wrote can ever be quoted. Prerendering fixes it without giving up a dynamic site.
Integration
Storing UTC is necessary and not sufficient. A daily 09:00 reminder computed by adding 24 hours drifts to 08:00 the day the clocks change — here is that bug, measured, and the four others around it.
AI & Data
OCR gives you text with no structure. A regex pass takes the fields that are certain, a model handles what is genuinely ambiguous, and a confidence score decides what a human still has to look at.
Integration
new Function gives the user your permissions. Node's vm module looks like a sandbox and escapes in one line. The safe option is a grammar small enough that there is no path to the host at all.
Integration
The canvas is the easy part. What decides whether the product survives is storing flows as a versioned graph, keeping runs separate from definitions, and pinning each run to the version it started with.
