Model Optimization: From FP16 to Speculative Decoding
A timeline tracking how deep learning model optimization evolved from FP16 mixed precision and INT8 calibration to outlier-aware AWQ, speculative decoding, and …
Your Model Isn’t the Bottleneck. Your Queue Is.
A classifier consumed 0.3% of request time; the queue ate the rest. Why AI deployments fail around the queue, not the model.
AI Agents Don’t Need More Memory. They Need Better State Management.
Memory alone doesn't solve agent problems. Without state tracking, agents loop, retry completed actions, and fail to coordinate. Here's what actually works.
Agents Aren’t Chatbots: Why Distributed Systems Matter
AI agents make API calls, manage state, and fail under load. Treat them like distributed systems, not chatbots. Backoff, idempotency, and structured traces aren…
cua: Computer-Use Automation at Scale
An open-source framework for cross-OS computer-use agents with built-in benchmarks and fleet infrastructure — protocol-first, evaluation-native, fleet-aware.
Sandboxing Autonomous AI Coding Agents: Ephemeral Containers and Egress Boundary Enforcement
Infrastructure security engineer Alex Chen discusses container sandboxing, system call filtering with seccomp and Landlock, and network egress boundaries for au…
Cache Invalidation via Surrogate Keys: Edge Architecture and Purge Mechanics
Decouple cache invalidation from URL paths using Surrogate-Key headers for targeted CDN purging.
Why MoE Models Stream From NVMe: Kernel Prefetch, Read-Ahead, and Async I/O
Frontier MoE models run on consumer hardware by streaming expert weights from disk. Not compression—kernel I/O prefetching overlapped with GPU compute. Here's h…
SSH Certificates vs. Key Files: Why Production Ops Teams Are Finally Moving
Key files don't scale. SSH certificates solve revocation, audit trails, and onboarding at production scale—here's why adoption is accelerating.
Kernel Socket Tuning for High-Concurrency Load Balancers: TCP_NODELAY, TCP_FASTOPEN, and Listen Backlog
Disable Nagle, enable TCP Fast Open, tune listen backlog. Three socket parameters cut tail latencies 40–60% on modern load balancers.
