Cayu is a production-grade Python framework for building domain-specific AI agents with full lifecycle control, including context assembly, tool invocation, durable state management, and human oversight. Extracted from a software factory that deployed thousands of applications using specialized AI agents, Cayu addresses production challenges like process failures, state persistence, and cost attribution that existing agent SDKs overlook.
Apple launched the AirPods 5 with Active Noise Cancellation now standard at the entry-level $129 price point, down from the $50 premium required on AirPods 4. The upgrade brings 50% more noise cancellation, improved durability (IP57), studio-quality audio recording, and extended battery life, though the core H2 chip and open-ear design remain unchanged from previous generations.
CNET compares the iPhone Duo foldable to the Samsung Galaxy Z Fold 8, noting they share similar passport-style designs and $100 price difference. The Duo offers superior dust protection and wireless charging, while the Fold 8 has slightly better wired charging and dual selfie cameras. Samsung's known durability issues may influence consumer choice between the $1999 Duo and $1900 Fold 8.
Apple unveiled the iPhone Duo, its first foldable smartphone, featuring a compact palm-size design with a 5.4-inch cover screen and 7.6-inch inner display. It competes with Samsung's Galaxy Z Fold 8 Ultra, which offers a larger 6.5-inch cover screen, 8-inch inner display, and superior camera specs, though the iPhone Duo provides better durability with an IP68 rating and starts at $1,999 versus the Z Fold 8 Ultra's $2,100.
A programmer discovers that fsync() doesn't guarantee data durability the way commonly assumed, as multiple storage layers between application and disk have different definitions of "done". The article explains how write() only puts data in the page cache, not on disk, and how journaling filesystems add complexity to data persistence guarantees.
Apple's iPhone Duo and Google's Pixel 11 Pro Fold are premium foldable phones priced around $2,000, both featuring rare IP68 water and dust resistance ratings. They differ in design philosophy: the Duo uses a compact passport-style layout with a matte inner display, while the Pixel 11 Pro Fold adopts a traditional book-style design with a larger screen. Both support dual apps and offer distinct trade-offs in form factor, display size, and camera capabilities.
Oh My Subagents is a local runtime that enables durable, persistent delegation between parent and child AI agents for Codex and Claude users, maintaining state across interruptions and providing accountability through workflow definitions and immutable task assignments. It moves coordination into persistent runtime state rather than relying on polling loops or chat history, allowing managers to choose execution patterns dynamically while preserving complete checkpoints and audit trails.
A ranking of iPhone Pro materials—titanium, stainless steel, and aluminium—across five dimensions: feel, look, features, durability, and weight. Titanium excels in feel and durability; stainless steel in appearance; aluminium in features and thermal performance. The author reflects on how material choices affect the user experience across generations.
AWS Lambda now supports 90-minute function timeouts for asynchronous and event source mapping invocations on Lambda Managed Instances, a sixfold increase from the previous 15-minute limit. This enables longer-running workloads like media transcoding, financial calculations, and AI inference without requiring application re-architecture. Synchronous invocations retain the 15-minute maximum timeout.
Apple's new iPhone Duo foldable smartphone features IP68 dust and water protection, matching Google's Pixel Fold, but both companies note this rating is temporary and may degrade with normal wear due to moving parts in foldable devices. Samsung's Galaxy foldables currently offer only IP48 protection.
Wiggle is a durable workflow engine that models business processes as graphs and executes them as state machines surviving crashes and worker failures. It features cellular architecture for multi-tenant isolation, pull-based gRPC workers supporting multiple languages, and can run embedded or distributed without external dependencies.
Samsung clarified that slight screen sinking at Galaxy Z Fold 8 corners is intentional design, not a defect. The cushioning structure provides durability and protection by allowing clearance between internal display components.
