PyDESeq2 brings the DESeq2 differential expression workflow to Python, letting users load bulk RNA-seq counts, specify design formulas, fit DESeq2 models, run Wald tests with FDR correction, optionally apply apeGLM shrinkage, and export gene-level statistics within pandas/AnnData pipelines.

Probabilistic deep-learning framework built on PyTorch for single-cell omics; handles batch correction, integration, multimodal and spatial data, differential expression, and transfer learning with unified APIs.

This comprehensive guide covers the full lifecycle of Apify Actors, enabling deployment from local environments to production platforms. Learn to trigger scraping tasks via APIs (e.g., Next.js routes), consume structured data, and handle results asynchronously using webhooks in frameworks like Express.js. Ideal for building robust, data-driven web services and automating data pipelines.

Implements comprehensive webhook handling for Miro boards. This solution allows external applications to subscribe to real-time events (create, update, delete) occurring on specific boards. It covers board subscription creation, event payload parsing, signature verification, and robust asynchronous event processing using TypeScript/Express.js, enabling seamless integration with external systems.

This guide demonstrates how to set up a secure and robust webhook endpoint to process identity verification events from Persona. It covers essential security practices, including HMAC signature verification using TypeScript and Express, handling critical KYC lifecycle events (like inquiry approval/declination), and implementing idempotent processing to prevent data duplication. Ideal for integrating third-party identity services into a web application.

This guide demonstrates how to set up a complete development environment entirely within a web browser using the WebContainer API. It covers mounting a virtual file system, installing Node.js dependencies via npm, and starting a local dev server (like Express) without needing a dedicated backend server. It is ideal for learning WebContainers, building browser-based IDEs, or prototyping Node.js applications client-side.

This wrapper provides a mechanism to integrate x402 payment walls into Node.js/Express APIs. It enforces micropayments (USDC on Base L2) for API access, enabling robust machine-to-machine (M2M) monetization. By acting as middleware, it requires valid payment signatures, ensuring that every API call is monetized and payments are liquidated atomically.

This utility evaluates complex arithmetic expressions using arbitrary-precision decimal mathematics. It is specifically designed for scientific, financial, or engineering calculations where standard floating-point arithmetic causes unacceptable rounding errors (e.g., 0.1 + 0.2). Supports addition, subtraction, multiplication, division, exponents, and parentheses.

An expert guide covering advanced exploitation techniques for Expression Language (EL) injection across multiple Java frameworks, including Spring (SpEL), Struts2 (OGNL), and JSP/JSF (Java EL). Details detection methods, sandbox bypasses, and real-world CVE chains for Remote Code Execution (RCE).
