It might not feel all that different from older World Cups—for better or worse.

Cindy Zhang discusses the evolution of XDS, a unified UI system powering 10,000+ internal tools. She shares actionable insights for architects and engineering leaders on managing large-scale community contributions, executing safe monorepo refactors using JS AST and AI codemods, mitigating breaking changes via feature flags, and expanding UI libraries into full-stack platform systems.

European economy airline Ryanair is under investigation in the UK for charging parents mandatory fees to sit with their children. The Competition and Markets Authority (CMA) said it was looking into whether the seating fees, which may be charging parents for the airline to meet its child safety and disability‑related obligations, are "unfair" under consumer […]

Electricity demand from AI data centers is pushing everyone — including automakers like GM and Ford — into the energy storage business.

Wing is expanding into seven more U.S. cities through its partnership with Walmart.

Waymo made a virtual driver called ReD to help its robotaxis avoid accidents.

Adi Polak discusses the architecture required to transition from stateless prompts to state-aware, context-rich AI agents. Drawing on 15 years in distributed systems, she shares how engineering leaders can leverage Apache Kafka and Flink for real-time stream processing, dynamic memory tiering, and tool orchestration via MCP to solve token limits, cost spikes, and latency bottlenecks.

Chinese EV colossus BYD has announced plans to speed up its conquest of the European auto market with the rollout of superfast Flash Chargers across the continent. BYD has already installed the first new chargers in Germany and the UK, and plans to roll out 3,000 across Europe by the end of next year. At […]

Waymo created a new computer model to help it better understand how humans behave in crash scenarios that its robotaxis encounter.

Waymo has a lot of experience building virtual systems to help its autonomous vehicles better understand the real world. It built realistic 3D worlds to better anticipate natural disasters and unpredictable edge cases. It created a virtual representation of a hyperattentive driver to test against its own autonomous vehicles in a series of simulated scenarios […]

The exec, Emad Dlala, has left just a few months after being promoted to SVP of engineering and digital, TechCrunch has learned.

EVs from GM will soon be able to top up at more kinds of public chargers.

GM is developing an entirely new sodium-ion battery chemistry for use in everything from data centers to its own factories.

Voice translations preserve speaker's tone, pacing, pitch—with SynthID watermarks for security.

Imagine a simple money transfer scenario. John sends money to his friend Sarah. The system successfully deducts money from John's account, but before it can credit Sarah's account, the application crashes. Without proper safeguards, John's money would disappear from the system, creating inconsistent and unreliable financial records. To prevent this type of problem, database transactions are used. Transactions ensure that a group of related database operations either complete successfully together or fail together. If any part of the process encounters an error, all changes are reverted, ensuring that the database remains consistent. Transactions make database operations atomic. Atomicity means that all operations inside a transaction are treated as a single unit of work. Either every operation succeeds and is committed to the database, or all operations fail and are rolled back. Partial updates are never permanently stored. A database transaction is a group of one or more database operations executed as a single unit. Either all operations succeed together or all operations fail together. This guarantees database consistency even if an application crashes, a network failure occurs, or an unexpected error is encountered during execution. It is important to understand that a transaction is not simply a single database query. While individual queries such as save, update, or delete interact with the database, a transaction wraps multiple queries inside a controlled all-or-nothing boundary. This prevents partial updates and ensures data integrity throughout the process. Prerequisites Before starting, make sure you have the following: Basic knowledge of NestJS Basic understanding of TypeORM Basic knowledge of PostgreSQL Understanding of basic database operations (save, update, delete) in TypeORM Project Setup In this article, we will create a simple NestJS application to demonstrate the importance of transactional queries when multiple database write or update operations

Founder and CEO RJ Scaringe has called it "maybe the most important thing we've launched to date."

It's not perfect, but Rivian's latest shows this company is playing for keeps.

Rivian may be all in on robotaxis and autonomy, but it's still got human drivers - and EV buyers - to win over. The pricey R1S SUV and R1T pickup brought Rivian A-list media attention and cult-hit status, but the company faces a critical next step. The 2027 R2 is Rivian's bid for mainstream success, […]

Netflix engineer Casey Bleifer shares how to achieve rapid, automated code changes across a massive, diverse software fleet. She discusses building an event-driven orchestration platform using composable, Lego-like steps, and explains how Netflix utilizes automated canary validation, compliance checks, and a custom "confidence metric" to eliminate the long tail of manual engineering migrations.
