Build WireMock mappings fast from real traffic

I’m a big fan of service mocking. I’ve been working in and around software for about 25 years, and one thing never changes: when you sit down to work on your code, you almost never have everything available. The database, the third-party API, the message queue, the service two teams over. Something’s missing. So you’ve got to stub it out or mock it out and keep moving.

Guessing AI vs. Verifiable AI: Why the Difference Matters in Finance

I asked Claude what the cash position would be at year-end. The answer was about 30% off. A CFO said this at a finance leaders breakfast in Prague. Almost every CFO in the room had a version of the same story. The problem is not the model. Claude is not bad at maths. The problem is what the model was reasoning over - raw financial data with no governed definitions, no intercompany rules, no agreed methodology for what 'cash position' means at that specific company.

Why Your Rolling Forecast Is Always Stale

Every FP&A team knows the feeling. The reforecast was published on Monday. By Wednesday, someone in sales has closed a deal that changes the revenue picture. By Friday, procurement has flagged a cost overrun that nobody modelled. The forecast is four days old and already partially wrong. This is not a forecasting problem. It is a data pipeline problem. Finance teams hired analysts for their analytical skills.

Why Your Chart of Accounts Breaks at Every Acquisition

You closed the deal. The press release went out. Integration planning is underway. And somewhere in the finance team, a controller is opening a spreadsheet and starting to map 1,400 account codes from the acquired company's ERP into your group chart of accounts. This is the moment the chart of accounts breaks. Not dramatically. Not all at once.

WWDC 2026: Device Hub and what it means for CI/CD

At WWDC 2026, Apple shipped a long list of changes, and we covered the ones flying under the radar in our round-up of the less-reported announcements. One of them deserves a closer look on its own: the way Xcode 27 reshapes how developers manage devices and simulators. Xcode 27 ships with a new app called Device Hub, replacing Simulator.app found in older Xcodes. Device Hub is where both physical devices and simulators can be managed from now on.

What is SonarQube and how does it work?

SonarQube is a code quality and security platform that helps teams detect bugs, vulnerabilities, and maintainability issues early in development, using static code analysis rather than manual reviews. SonarQube fits directly into modern workflows, integrating with CI/CD pipelines and development environments to continuously verify code through quality gates, dashboards, and automated checks. And in this guide, we’ll give you.

Multiplayer is now open source

The Multiplayer debugging agent is open source under MIT. Here's why, and what it means for how you use it. Today we're open sourcing the Multiplayer debugging agent: connect your favorite coding agent to prod to fix application bugs automatically. Run it locally and eliminate PR slop. The core (session-based data capture, local-first architecture, intelligent deduplication, and coding agent integration) is publicly available under MIT, free to use, and auditable by anyone.

How Structured Content Improves Financial Product Communication

Financial product communication has to be clear, accurate, and easy to understand. Customers often compare banking products, insurance options, investment services, loans, credit cards, payment solutions, and savings accounts before making a decision. Each product may include detailed information about fees, eligibility, benefits, terms, risks, application steps, and support options. When this information is presented in a confusing or inconsistent way, customers may struggle to understand what a product offers and whether it is right for their needs.

How to Build a BaaS Platform: Architecture, Licensing, and Go-to-Market Engineering

Banking as a Service is no longer sitting quietly behind fintech apps. It is becoming the infrastructure layer powering modern digital businesses. SaaS platforms want wallets and embedded payments. Ecommerce companies want merchant banking features. Healthcare apps want financing and payout rails built directly into patient workflows. According to Bain & Company, embedded finance transaction value in the US alone could exceed $7 trillion by 2026.
