Architecting Trustworthy AI: Engineering Patterns for High-Stakes Environments

Software engineers are great at talking about how to make things dependable: we have names for things like circuit breakers, bulkheads, making sure something can be done multiple times with the same result (idempotency), and making sure a system will fall apart in a manageable way (graceful degradation). We're good at building systems to fail safely if a database isn't working or a dependent service is taking too long. However, we don't have a comparable, well-defined way of discussing systems t

Quantum computing startup says it will leapfrog everybody

But the system would require a massive leap from any of its existing hardware.

Pair Nova 2 Lite with Claude for cost-optimized document processing

In this post, we show how pairing Amazon Nova 2 Lite with Anthropic’s Claude Sonnet 4.6 delivers an efficient solution for digitizing scanned documents at scale. We built a two-model pipeline on Amazon Bedrock for digitizing scanned yearbook pages. Amazon Nova 2 Lite handles native multimodal extraction in a single call: detecting photos, extracting visible names with coordinates, and returning page-level metadata. Claude Sonnet 4.6 then performs spatial reasoning to match names to faces based o

At $499, Apple’s M3-powered iPad Air is a good deal

The iPad Air supports Apple Pencil Pro, plus hover support. | Photo: Antonio G. Di Benedetto, The Verge Most of Apple’s price increases have gone into effect, resulting in iPads and other products costing hundreds more than they did a few days ago. If last week’s Prime Day sale wasn’t a good time to consider buying an iPad, we found a deal worth considering that’s just under $500 right now. The 128GB iPad Air that has the M3 processor, plus both Wi-Fi and 5G cellular support, costs $499 at Be

Multi-tenant LLM analytics with row-level security: How we built a secure agent on AWS

In this post, we show you how PAR built a production-ready multi-tenant LLM analytics system that enforces row-level security through a three-layer architecture: cryptographic request signing with AWS SigV4, semantic validation on Amazon Bedrock, and programmatic data isolation via Split-Plane SQL. We demonstrate how each layer operates independently to reduce the risk of cross-tenant data exposure, even when the LLM itself is compromised or manipulated.
