Separating Password Reset Email From Logistics Reports to Protect Delivery Evidence

·2 views

The article argues that password-reset emails should use an authenticated sender subdomain and a traffic stream separate from generated logistics reports. It explains that SPF, DKIM, and DMARC establish sender authorization and alignment but do not guarantee inbox placement or prove a user read the message. The author stresses tracking application enqueue, remote acceptance, classified bounces or complaints, and reset completion as distinct events rather than treating SMTP acceptance as delivery. The piece also recommends a dedicated queue and worker budget for recovery traffic so large report attachments do not delay time-sensitive resets. Failure handling is outlined, including suppressing permanent address failures and applying bounded retries to temporary deferrals.

Tracking Google Flights prices with Python via a scraper, no API key needed

Google Flights offers no public API, so the article proposes a scraper-based approach to monitor fares across many routes and dates. The author's Apify Actor, Google Flights Scraper, collects total price, airlines, times, duration, stops, layovers, leg details, CO2 emissions, and a direct booking link for each flight. Users specify origin and destination airports and date ranges, and can filter by cabin class, stops, currency, and round-trip length. A short Python script using the Apify client exports the cheapest fare per departure date to CSV. The article also explains how to schedule daily runs to track price changes, noting the disclosed cost of roughly $0.20 per 1,000 flights.

Paused CDC Connector Left Replication Slot Holding WAL, Filling Postgres Disk

A Postgres primary database shut down after its disk filled, because a paused CDC connector's replication slot had kept all write-ahead log since it was stopped nine days earlier. Replication slots record the oldest WAL position a consumer needs, and by default Postgres retains that WAL without limit, so it keeps growing while the connector is idle. A quieter variant can occur even when the connector runs, if captured tables rarely change and the confirmed position lags behind. The article recommends heartbeat settings, including a dedicated heartbeat table in the captured database, plus Postgres safeguards such as max_slot_wal_keep_size and idle slot timeouts.

CrewAI and AutoGen Compared on Coordination, Token Use, and Stability for Multi-Agent Systems

A DEV Community analysis compares CrewAI and AutoGen, the two leading multi-agent orchestration frameworks used in production AI engineering. CrewAI uses role-based hierarchies and deterministic Flows, while AutoGen relies on conversational, message-passing agent groups. In benchmarks of 5,000 multi-step research and code triage tasks on Python 3.12 with GPT-4o and Claude 3.5 Sonnet, CrewAI's structured Flows reportedly cut token waste by 46%. The article says CrewAI also reduced runaway chat loops by 91.4% in business pipelines, whereas AutoGen offers greater flexibility for open-ended, exploratory debugging.

Freelance web designers can protect profits by setting clear client revision limits

A DEV Community guide explains how freelance web designers can manage client revisions without losing money. It recommends stating a fixed number of included revision rounds in the contract instead of offering unlimited changes. The guide advises separating routine revisions from scope changes, such as adding new pages or features, which should be quoted separately. It also suggests tracking feedback, reminding clients of remaining rounds, and securing approvals at staged milestones before development begins.
