Developer releases 'canc', a JavaScript library for native promise cancellation

0
·1 views

A developer has publicly released 'canc', an open-source JavaScript library designed to bring straightforward promise cancellation to the language. The project began around 2017, originally motivated by compatibility issues between native async functions and Angular's Zone.js reactivity system. After nearly a decade of internal use, bug fixing, and design refinements, the library reached a stable public release. 'canc' uses a generator-based approach, allowing developers to cancel entire promise chains with a simple .cancel() call, without relying on AbortController or manual flag variables. The library also integrates with AbortSignal for broader platform interoperability and is available on GitHub under the cancjs organization.

Flawed LLM Eval Harnesses Can Blame Models for Their Own Congestion

A common mistake in LLM evaluation occurs when a test harness opens too many concurrent requests, triggers rate-limiting (HTTP 429 errors), and then retries those requests — effectively doubling the intended load on the endpoint. This causes client-side queueing delays to inflate observed latency figures, meaning the harness is measuring its own congestion rather than the model's true performance. The result is misleading metrics: a reported p99 latency of 8.4 seconds, for example, may include roughly 6 seconds of queue-wait time that has nothing to do with the model. The recommended fix is a closed-loop harness that caps in-flight requests and separates queue-wait time from actual service time, ensuring measured latency reflects endpoint behavior. This approach also enables systematic discovery of an endpoint's concurrency limits by sweeping the concurrency gate upward until throughput plateaus and 429 rates rise.

Fix Shopify Google Ads tracking gaps with free server-side conversion pipeline

Shopify stores using browser-based Google Ads pixels miss 20–40% of conversions due to Safari tracking protections, cookie lifespan limits, and ad-blocking extensions. Google's Enhanced Conversions offers a server-side alternative by sending SHA-256 hashed customer identifiers directly to Google's API, which then matches purchases to logged-in Google accounts. This approach recovers attribution even when a user clicks an ad on one device and completes checkout days later on another. Rather than using paid Google Tag Manager server containers costing $10–$30 per month, developers can build a direct webhook pipeline triggered by Shopify's orders/paid event. The middleware hashes customer data and posts it to the Google Ads API endpoint, eliminating third-party infrastructure while restoring accurate conversion data for smart bidding.

Why Defaulting to Global State Management Often Creates More Problems Than It Solves

A software developer reflects on three years of over-relying on global state management tools like Redux and Zustand for every data-sharing need in frontend applications. The core mistake, they argue, is conflating 'shared state' with 'global state,' which leads to tightly coupled components, harder testing, and unnecessary re-renders. The developer now follows a decision hierarchy — local state, lifted state, server cache, then global state — before deciding where data should live. A key insight is that API responses are better treated as a server cache using dedicated tools, which can eliminate up to 60 percent of global state code. The advice concludes that simpler, more targeted state management is more maintainable and scalable than defaulting to a global store.

Nashville invokes eminent domain to block hyperscale data center near city zoo

The Nashville Metropolitan Council has used eminent domain to acquire land that had been designated for a large-scale data center development. The decision was driven by concerns over the facility's potential impact on local aquifers, natural habitat, and its proximity to the Nashville Zoo. Hyperscale data centers typically demand between 50MW and 200MW of power and consume significant volumes of water for cooling, raising environmental red flags for urban sites. The move is legally notable because the proposed development was reportedly compliant with existing zoning rules, marking an unusual use of eminent domain to block rather than enable infrastructure. Experts warn the decision creates regulatory uncertainty that could deter future infrastructure investment across the jurisdiction.
