Ruby gem 'fundamentalista' pulls free SEC EDGAR data for stock fundamental analysis

·2 views

A new Ruby gem called 'fundamentalista' enables developers to perform fundamental analysis on publicly listed companies using data sourced directly from SEC EDGAR's free XBRL filings. Version 0.6.0 is now available on RubyGems and supports both US GAAP and IFRS filers in their respective reporting currencies. The gem provides income, balance sheet, and cash flow data alongside valuation metrics such as P/E ratios, discounted cash flow, Altman Z-score, and Piotroski F-score, all accessible through a clean, object-oriented API. It also integrates with Financial Modeling Prep for quotes, estimates, and exchange rates when an API key is provided. A companion Rails engine, 'fundamentalista-rails', adds watchlist functionality with ratio and valuation snapshots per holding.

OpenPledge Uses Blockchain and AI to Make Charity Donations Fully Transparent

A developer has built OpenPledge, an open-source donation platform designed to give donors complete visibility into where their money goes. Every contribution is recorded on the Solana blockchain, creating a permanent, publicly verifiable transaction record that cannot be altered. Google Gemini generates a personalised thank-you message for each donor, which ElevenLabs then converts into spoken audio, while Snowflake powers a public Impact Dashboard showing aggregate giving trends. The platform requires no login and features a public ledger linking every donation directly to its on-chain record. OpenPledge was submitted as part of a weekend developer challenge and is currently live at open-pledge.vercel.app, with full source code available on GitHub.

WebForms Core 2.1 Introduces WPC Criteria as an Advanced Alternative to CSS Selectors

WebForms Core 2.1 has expanded its built-in domain-specific language, WebForms Place Criteria (WPC), which allows developers to select, filter, and manipulate HTML and DOM elements. Unlike standard CSS selectors, WPC Criteria enables filtering of already-selected elements based on text content, attributes, visibility, state, position, and DOM relationships. Developers can chain multiple conditions and apply operators to build complex selections that go beyond simple ID, class, or tag-based queries. WPC also supports text searches and attribute-value matching, such as finding elements whose attribute values end with a specific string. The feature is exclusive to the WebForms Core framework and is not available as a standalone or external tool.
