Spectral
A flexible JSON/YAML linter for creating automated style guides
An open-source API style guide enforcer and linter. Why write API Style Guides as lengthy manifestos when you could automate them? Make sure APIs are secure, consistent, and useful. Spectral is open-source but is also baked into Stoplight, with extensions for VS Code and other integration options, giving you real-time feedback wherever you design APIs. Spectral can be used as a generic ruleset engine on any JSON or YAML data but was built with OpenAPI, AsyncAPI, and JSON Schema in mind. Use Spectral rules to target API descriptions for quality improvement or enforce API Style Guide rules, such as naming conventions for OpenAPI models or prohibiting integers in URLs. -

reverse-SynthID
Reverse engineering Gemini's SynthID detection
Reverse-SynthID is a research-focused project that analyzes and reverse-engineers Google’s SynthID watermarking system used in AI-generated images. It leverages signal processing and spectral analysis techniques to identify hidden watermark patterns without access to proprietary encoding methods. The project introduces a multi-resolution “SpectralCodebook” that maps watermark characteristics across different image sizes. Using this approach, it can detect SynthID watermarks with high accuracy and selectively reduce or remove them through frequency-domain manipulation. ... -

...Traditional quantitation pipelines for isobaric-labeled MS data are based on sequence database searching. We present a novel quantitation pipeline which integrates sequence database searching, spectral library searching, and a feature-based peptide-spectrum-match (PSM) filter (FPF) using various spectral features for filtering. The combined database and spectral library searching results in larger quantitation coverage, and the filter removes PSMs of larger quantitation error, retaining those of higher quantitation accuracy. The proposed pipeline is fully compatible with the Trans-Proteomic Pipeline and can be executed on Windows, Linux, and MacOS platforms.
