14.6 Million Official Exchange Rates from 107 Institutions Now Free on Hugging Face

·1 views

A newly published dataset on Hugging Face aggregates over 14.6 million official exchange rates sourced from 103 central banks and 4 tax authorities across the globe. The dataset covers historical records dating as far back as 1914, with the Swiss National Bank providing the earliest data, and spans 215 base currencies and 202 quote currencies. Unlike market-rate aggregators, these are the official published fixings used by regulators, tax offices, and customs agencies — such as ECB reference rates and Reserve Bank of India benchmarks — which cannot be derived from interbank market data. The data is structured in a consistent five-column CSV format per institution and is refreshed daily from a GitHub source repository. Released under a CC BY 4.0 license, the 515 MB dataset is freely accessible and also available in Parquet format via the Hugging Face datasets library.

Baidu's LoongForge Framework Cuts Embodied AI Model Training Time in Half

Baidu has released LoongForge, an open-source framework designed to accelerate the training of embodied AI models, available on GitHub. The framework supports a range of mainstream embodied AI models including pi05, GR00T, xVLA, FastWAM, and DreamZero, among others. It is designed to work out of the box and claims to deliver roughly 200% acceleration, effectively halving training time without altering model outputs. The release aims to address growing challenges in AI development such as expanding task lists, longer experiment queues, and rising compute costs. Baidu is inviting the open-source community to contribute, raise issues, and collaborate on further development of the project.

FUI-RS lets Rust apps run natively on desktop and browser without Electron

FUI-RS is an early-access, cross-platform UI framework written in Rust that targets both native desktop and web browsers under a single application model. The framework includes core UI components such as controls, layouts, themes, event handling, dialogs, and custom drawing, all built on a shared architecture to avoid separate codebases. Because it is pre-1.0, its APIs remain subject to change, but the project is open to community contributions and issue reports. A community-developed Galaga-style space shooter already runs on FUI-RS, serving as a practical stress test for the young framework. The project is publicly available on GitHub for Rust developers interested in exploring cross-platform UI development outside the Electron ecosystem.

HMAC-Signed Cookies Offer a Faster, Cache-Friendly Alternative to PHP Sessions

A developer on DEV Community has detailed a method to replace PHP's session_start() in paywall implementations using HMAC-signed cookies and single-use recovery links. The traditional session-based approach causes two key problems: access is lost when the browser closes, and session headers prevent CDNs and page caches from caching responses for any visitor. The proposed solution uses a 90-day HMAC-signed cookie that encodes a user's email and expiry timestamp, verified server-side without storing any session state. A separate single-use recovery link, valid for 24 hours, allows purchasers to restore access on a new device. The design, drawn from a WordPress plugin, is framework-independent and incorporates security measures such as timing-safe hash comparison and structurally enforced payload parsing.

Open-Source JS/TS Library Offers Transliteration Across 50 Languages and 2,450 Pairs

A developer has released a JavaScript and TypeScript library designed to handle transliteration between 50 of the world's most popular languages, covering 2,450 directional language combinations. Unlike most existing tools, which only convert non-Latin scripts into Latin characters (romanization), this library also supports transliteration from Latin-based languages into scripts such as Arabic, Chinese, Hindi, and Greek. The library aims to produce accurate, human-readable results by applying language-specific orthographic rules rather than simple letter-by-letter substitution. It is self-hosted and free to use, addressing limitations found in alternatives like Google Translate API and AI tools, which can mistranslate, hallucinate, or incur costs. The project's stated goal is to enable speakers of a target language to correctly pronounce words originating from a source language.
