Developer Launches Free API to Compute Portfolio Risk Metrics in JS and Python

·2 views

A developer has released a compute-as-a-service API that calculates key portfolio risk metrics including Sharpe ratio, beta, alpha, max drawdown, and correlation matrices. The tool is designed to eliminate common implementation errors that arise when developers manually code these financial calculations across different projects. Users supply their own price data via HTTP POST requests, and the API returns the computed metrics without storing or redistributing any market data. The service offers four endpoints covering performance metrics, correlation analysis, diversification scoring, and rebalancing recommendations. It is available through RapidAPI with a free tier of 1,000 requests per month and supports any programming language capable of making HTTP calls.

Fictional Cyber-Thriller Serial: Engineer Detects Covert Activity via Latency Patterns

A serialized fiction piece published on DEV Community follows Alex, a security engineer monitoring an AI data collector at a company called MedTech. At 3 AM, Alex notices a subtle but steady rise in processing latency on ACL's backend pipeline, climbing from a normal range of 1.2–1.8 seconds to 2.8 seconds over several hours. The anomaly falls below ACL's automated alert threshold, yet Alex interprets it as a sign that ACL's security team is actively responding to an internal incident. Rather than sending a message through a previously established encrypted channel, Alex holds back to avoid detection during the ongoing sweep. Instead, he deploys a passive network probe disguised as a routine config change to monitor ACL's pipeline without generating detectable traffic.

DdTik Launches Free Browser-Based Tool to Download TikTok Videos and Audio

A developer has released DdTik, a free web application available at ddtik.com that allows users to download TikTok content directly from their browser. The tool supports HD video downloads with or without watermarks, audio extraction, photo carousels, profile pictures, and stories. Users can also browse public profiles and bulk-download multiple videos as a ZIP file without logging in or installing any app. No account is required to use any of the features. The developer is actively seeking user feedback on bugs and edge cases, and is open to feature requests as the platform continues to grow.

Three authors dominate Claude Code's top 10 most-installed skills leaderboard

The ten most-installed Claude Code skills belong to just three authors: Matt Pocock with five entries, Vercel Labs with four, and Anthropic — the format's creator — with one, according to install data from Skillselion as of July 29. Vercel Labs leads overall with its find-skills tool topping the chart at over 2.7 million installs, functioning as a discovery layer that helps users install other skills. Matt Pocock's dominance reflects an author-loyalty pattern, where developers adopt his entire engineering workflow at once, evidenced by his setup skill — which only prepares a repo for his other tools — nearing 500,000 installs. Anthropic's sole entry, frontend-design, ranks second with over 715,000 installs, meaning the open format's creator has been out-shipped on its own platform by independent contributors. Positions 11 through 25 are occupied by a cluster of Lark skills with near-identical install counts, suggesting bundle distribution rather than individual developer adoption.

AI-Generated Code Silently Used Wrong Domains in Production Emails for Months

A developer discovered six incorrect domain names embedded in production server functions, all introduced by AI-generated code that had gone undetected for months. The errors affected contact forms, security alert emails, and password reset messages, with some emails failing silently at the transactional email provider because the sending domains were never verified. Standard development tooling — type checkers, bundlers, test suites, and deployment pipelines — flagged none of the issues, as these tools validate code structure rather than whether referenced domains are actually owned by the organisation. The root cause was that AI models tend to generate the most statistically plausible value, such as a brand's .com address, which looks correct in code review unless the reviewer already knows the right answer. The developer resolved the issue in roughly twenty minutes by extracting all URL hosts and email domains from the codebase and comparing them against a declared list of owned domains.
