Weekend Reading #74

Weekend Reading: A weekly roundup of interesting Software Architecture and Programming articles from tech companies. Find fresh ideas and insights every weekend.

This week: Cloudflare’s MCP code mode, Uber’s database federation, Wix’s shift from prompting to AI management, and LinkedIn’s LLM-based ranking at scale.

Code Mode: give agents an entire API in 1,000 tokens

👉 Interesting if you’re building AI-native developer tools or internal coding assistants.

Cloudflare introduces Code Mode MCP, a way to integrate AI models directly into developer workflows. It connects code, context, and models in a more structured way than ad-hoc prompting.

Database Federation: Decentralized and ACL-Compliant Hive™ Databases

👉 Useful if your architecture spans many databases and teams need unified access.

Uber explains how it built a database federation layer to unify access across multiple storage systems. The solution simplifies querying while preserving performance and isolation.

Stop Prompting, Start Managing

👉 Great read if you’re moving from experimental prompts to production AI systems.

A Wix engineer shares how he replaced ad-hoc AI prompting with a structured discipline system — treating AI agents like junior engineers who need context, specs, reviews, and enforced rules to become reliable engineering partners.

Scaling LLM-Based ranking systems with SGLang at LinkedIn

👉 Valuable if you’re integrating LLMs into high-throughput recommendation or ranking pipelines.

LinkedIn shares how they use SGLang to scale LLM-powered ranking systems. The platform improves efficiency and latency while handling large traffic volumes.
