Vibe coding has turned senior devs into โ€˜AI babysitters,โ€™ but they say itโ€™s worth it

Fastly says95% of developersspend extra time fixing AI-written code. Senior engineers take the brunt. That overhead has even spawned a new gig: โ€œvibe code cleanup specialist.โ€ (Yes, seriously.) As teams lean harder on AI tools, reliability and security start to slideโ€”unless someone steps in. The re.. read more ย

Guardians of the Agentsย 

A new static verification framework wants to make runtime safeguards look lazy. It slaps **mathematical safety proofs** onto LLM-generated workflows *before* they runโ€”no more crossing fingers at execution time. The setup decouples **code from data**, then runs checks with tools like **CodeQL** and .. read more ย

Introducing the MCP Registry

The new **Model Context Protocol (MCP) Registry** just dropped in preview. Itโ€™s a public, centralized hub for finding and sharing MCP serversโ€”think phonebook, but for AI context APIs. It handles public and private subregistries, publishes OpenAPI specs so tooling can play nice, and bakes in communit.. read more ย

Building Agents for Small Language Models: A Deep Dive into Lightweight AI

Agent engineering with **small language models (SLMs)**โ€”anywhere from 270M to 32B parametersโ€”calls for a different playbook. Think tight prompts, offloaded logic, clean I/O, and systems that donโ€™t fall apart when things go sideways. The newer stackโ€”**GGUF** + **llama.cpp**โ€”lets these agents run loc.. read more ย

Accelerate serverless testing with LocalStack integration in VS Code IDE

The AWS Toolkit for VS Code now hooks straight into **LocalStack**. Run full end-to-end tests for **serverless workflows**โ€”Lambda, SQS, EventBridge, the whole crewโ€”without bouncing between tools or writing boilerplate. Just deploy to LocalStack from the IDE using the **AWS SAM CLI**. It feels like .. read more ย

Magical systems thinking

AI now writes over **25% of Googleโ€™s** and as much as **90% of Anthropicโ€™s** code. Thatโ€™s not a trendโ€”itโ€™s a regime change. Still, the mess in large public systems reminds us: clever analysis isnโ€™t enough. Complex systems donโ€™t behave; they misbehave. When the machines are churning out code, the .. read more ย

PostgreSQL maintenance without superuser

PostgreSQLโ€™s moving in on superusers. As of recent releasesโ€”starting way back in v9.6 and maturing through PostgreSQL 18 (coming 2025)โ€”there are now **15+ built-in admin roles**. No need to hand out superuser just to get things done. These roles cover the ops spectrum: monitoring, backups, fil.. read more ย

Writing an operating system kernel from scratch

A barebonestime-sharing OS kernel, written inZig, running onRISC-V. It leans onOpenSBIfor console I/O and timer interrupts. Threads? Statically allocated, each running inuser mode (U-mode). The kernel stays insupervisor mode (S-mode), where it catchessystem callsandcontext switchesvia timer ticks. .. read more ย

SLI Evolution Stages

A new SLI evolution model lays out a maturity roadmapโ€”from rebranded latency/error metrics to ones that actually track business impact. It replaces shallow signals and pulls in the stuff that matters: how service failures hit user goals, tasks, and bottom lines... read more ย
