How Build Cache for React Native works: caching the C++ your CI keeps recompiling

A React Native build is really two builds stacked on top of each other. On Android, Gradle compiles your Kotlin and Java, then drops down into cmake and ndk-build to compile the C++ that ships inside Hermes, Folly, ReactCommon, and your own turbo modules. On iOS, Xcode does the equivalent: Swift and Objective-C on top, the same C++ underneath via Clang. Two build systems, two languages on top, one shared set of C++ underneath.

MLS Data Normalization at Scale: The Architecture Behind Fast PropTech Expansion

Your frontend can look flawless — fast search, clean filters, a map view that renders in under a second — and none of it will matter the day you connect your fifth MLS. Somewhere between the second and third regional feed, most PropTech teams hit the same wall: the code that worked beautifully for one market starts breaking in ways nobody predicted. A field that was always a number is suddenly a string. A boolean flag for “has pool” shows up as free text in the new feed.

12 Best Contract Testing Tools In 2026

I’ve watched enough production incidents get traced back to a "small" API change to know this: contract testing tools exist because integration bugs are expensive, and most teams find that out the hard way. One service changes a response field, nobody notices until a downstream consumer breaks in production, and now three teams are on a call at 11 PM figuring out whose change caused it. Most "best contract testing tools" lists just dump fifteen names on you with no structure.

Quality People: Gastón Marichal on Why Agentic QA's Hardest Problem Isn't the Technology

A conversation with Gastón Marichal, QA Manager at QAlified, on why the hardest part of agentic QA has nothing to do with the technology. In the first installment of this series, we heard from Huy Tieu, a Katalon product manager building an AI quality companion from the inside. This time we wanted the other side of the table: someone who has to make agentic QA work for real client teams, on real delivery timelines, with real consequences if it goes wrong.

CI/CD Testing: Complete Guide To Continuous Testing (2026)

CI/CD testing is the practice of running automated tests throughout a Continuous Integration and Continuous Delivery (CI/CD) pipeline to validate every code change before deployment. By automating unit, integration, API, and end-to-end tests, teams can catch bugs early, improve code quality, and release software faster with confidence.

What Is Vibe Testing? A Practical Guide For Developers

Vibe testing is what happens when the way software gets built changes faster than the way it gets tested. For years, QA worked on a simple assumption: developers write the code, testers verify it. That assumption breaks down when the code is being generated by an AI from a plain English prompt. The person shipping the feature may not have written a single line of it – and may not fully understand how it works under the hood.

Dependency Mocking and Service Virtualization: Make Every CI Test Deterministic

Dependency mocking replaces real external dependencies (APIs, databases, queues) with controlled substitutes during testing. Service virtualization extends this to enterprise scale, adding stateful simulation and protocol support beyond HTTP. Keploy implements a traffic-capture approach: it records real dependency interactions at the kernel level using eBPF and replays them in CI, making integration tests deterministic without manual stub writing.

Flexible Crypto Invoicing: How Configurable Payment Windows Support Complex Business Scenarios

Cryptocurrency transactions are widely recognized for their settlement speed, with transfers often processing and finalizing in just a few minutes. While rapid execution is a core advantage of blockchain technology, digital payment workflows must accommodate more than just instant execution. Many corporate setups-such as subscription billing, reservation management, account funding, and enterprise B2B contracts-require structural flexibility that standard automated systems cannot support due to internal approval delays or operational buffer times.

7 Best Unstructured Data Tools for Enterprise AI (2026 List)

Enterprise AI depends on data that was never designed for AI. Most business knowledge is not sitting neatly in rows and columns. It is spread across documents, emails, chats, tickets, logs, telemetry streams, PDFs, customer conversations, search indexes, knowledge bases, product content, operational systems, and digital experience platforms.

Best 7 Virtual CDN (vCDN) Providers in 2026

Organizations no longer deliver content through a single website hosted in one region. Modern digital services power everything from SaaS applications and ecommerce stores to media platforms, gaming environments, APIs, software downloads, and AI-driven applications. Every interaction depends on fast, reliable delivery regardless of where users are located or how network conditions change throughout the day.
