Google Cloud Serverless for Apache Spark, now available in BigQuery is an open-source, zero-ops, high performance, and unified analytics platform.

Relational databases rely on SQL, or Structured Query Language, as the standard way to control and interact with their stored data. In the Node.js ecosystem, Sequelize is a prominent Object-Relational Mapping(ORM) library that bridges the gap between Node.js apps and SQL databases, enabling you to interact with your data using familiar JavaScript idioms. This article will guide you through using Sequelize to connect to databases, run queries, and handle results within your Node.js projects.

Anyone who has tried to build a recommendation engine or a churn predictor knows the moment the excitement fades. The prototype looks good in the notebook, but the training data contains typos, half-missing properties, and events that somehow morphed between different devices. The model stumbles, engineers lose faith, and everyone wonders where all that AI magic went.

On April 16, the White House issued a clear directive to federal agencies: Stop building what you can buy. Reinstating that proven commercial software should be agencies’ first choice, and custom software should only be an option when no other options can meet the need.

Extend your data pipelines to custom tools, niche systems, and internal APIs.

Frontend coding has been transformed by JavaScript frameworks for more than a decade, with developers leaning on the robust tools to create interactive, responsive web applications. The advent of single-page applications and demand for improved user experiences have rendered frameworks indispensable in contemporary web development. In this detailed guide, we’ll delve deeply into the two most used frontend frameworks: Angular and React.

It's 2025, you can build a full-stack app by telling an AI what you want. Inspired by projects and tools like v0, Create, Replit, and Same, Neon built app.build: an open-source AI agent that builds and deploys full-stack web apps, straight from your terminal. Built for developers, app.build is local-first, extensible, and fully open source.

Engineering leaders usually outsource quality assurance (QA) to a software testing service to reduce developer workload, accelerate releases, and avoid the complexity of in-house QA teams. However, many engineering leaders mistakenly assume outsourcing automatically solves test creation and maintenance burdens and guarantees faster shipping. In reality, choosing the wrong service can exacerbate these problems.

Choosing the right QA outsourcing service isn’t just about considering the basics, such as their experience, certifications, and client feedback and reviews. You should evaluate their process for writing and maintaining tests, as this directly impacts your ability to ship fast and with confidence. From what we’ve seen, most QA outsourcing services use outdated, legacy frameworks like Selenium to write automated tests.

Deploying Phoenix applications in production environments poses unique challenges due to Elixir and the Erlang Virtual Machine (VM). The ecosystem offers multiple strategies — ranging from releases to mix-based approaches (as detailed in the Phoenix Deployment Guide) — and various platforms employ different methods. While some rely on buildpacks (for example, Heroku and Gigalixir), others use containerization (like Fly).
