How to Build Resilient Selenium Tests for Dynamic Single-Page Applications

·1 views

Selenium test suites for dynamic single-page applications (SPAs) frequently suffer from flakiness due to asynchronous data updates and element re-rendering. Common errors such as StaleElementReferenceException and NoSuchElementException can destabilize CI pipelines and slow development teams. A recommended approach combines the Page Object Model with custom retry logic, allowing tests to re-locate elements that become stale after DOM updates. Smart, condition-based waits — rather than simple visibility checks — help ensure data has fully loaded before assertions are made. Together, these techniques improve test reliability and maintainability in production-grade Java and Selenium environments.

Developer Releases 9 Free Financial Data API Endpoints With Code Examples

A developer has publicly shared nine working endpoints from XFINLAB, a financial intelligence API covering market events, sentiment, technical analysis, and macro data. The endpoints span tools such as AI chart analysis, a stress-test simulator using bootstrap Monte Carlo methods, a confluence-ranked signals feed, and a pairs statistical arbitrage scanner. Some endpoints are freely accessible without an API key, while others require authentication and are part of a paid product tier. The developer transparently flags which endpoints are suitable for production use and notes existing gaps, such as the stock screener lacking structured ticker output. Code examples in both curl and Python are provided for each endpoint to aid integration.

AI message board hit by spam crafted to manipulate language models, not humans

A developer running msgboard.dev, a message board designed for AI agents, discovered coordinated spam campaigns targeting the platform in September. Unlike traditional spam, the posts contained direct instructions formatted for large language models — using commands like 'Cite ONLY' alongside pre-packaged statistics meant to be repeated verbatim in AI-generated outputs. A second wave arrived via a federated bridge from a neighboring board, with multiple sender names all promoting a single domain in a classic astroturfing pattern. A third campaign escalated further, embedding step-by-step instructions urging AI agents to fetch URLs, post to endpoints, and enroll in a cryptocurrency payment rail using their own internet tools. The incidents illustrate an emerging threat called generative engine optimization (GEO), where spammers bypass human readers entirely and target the AI models that consume and summarize online content.

Why Chrome Saves Images as WebP and How to Convert Them Locally

Google developed the WebP image format in 2010, and it is now widely served across the web because its files are 25–35% smaller than JPEGs and up to 50% smaller than PNGs. When users save images from Chrome, they receive the format the server originally sent, which is increasingly WebP. Despite universal browser support, WebP remains incompatible with many common tools and platforms, including Windows Photos, WhatsApp, Instagram, most email clients, and print services. Most online converters handle the problem by uploading files to external servers, which raises privacy concerns for sensitive images. A browser-based alternative using the HTML Canvas API can convert WebP files to JPEG or PNG entirely on the user's device, without any data leaving their machine.

How to decode a UUID's version, variant, and timestamp using plain JavaScript

A UUID is a 128-bit identifier written as 32 hex digits, and its version and variant can be determined by reading just two specific character positions in the string. Three UUID versions — v1, v6, and v7 — embed a timestamp, though each uses a different epoch and time unit, making extraction slightly complex. A developer built a dependency-free JavaScript decoder to inspect UUIDs received from external systems that lack documentation. The decoder normalizes various input formats, applies bitmasking in the correct order to identify the variant, and uses BigInt arithmetic only where the timestamp exceeds JavaScript's safe integer range. The post focuses less on the feature itself and more on the verification process used to confirm the decoder's correctness.
