LOCKS — per-page SVD cuts KV cache reads 10 at 1M context

Every decode step loads the entire KV cache from GPU HBM. At 128K tokens that is several GB; at 1M tokens it exceeds 60GB. The bottleneck is memory bandwidth, not compute. The GPU waits while the memory bus transfers data that is likely irrelevant to the current query. Why shared-basis sparse attention is structurally broken Quest, ShadowKV, and RocketKV reduce this cost by estimating ...

Part 4 of the Angular in Production series One thing I've noticed after working on larger Angular applications is that components rarely becomes difficult to maintain overnight, it hapens gradually. When you add a feature and another, and new modals, new API calls and new permission checks. Nobody deliberately decides to create a thousand-line component. It simply happens because adding a little ...

Spring AI vs LangChain4j: Which Java AI Framework Should You Choose in 2026?

Earlier this year, I needed to add an AI assistant to a Spring Boot application I maintain. Nothing exotic -- just a chat interface that could answer questions about the system's documentation. I had two obvious choices: Spring AI or LangChain4j. I assumed it would be a quick decision. Both frameworks are mature. Both support the major LLM providers. Both have Spring Boot integrations. How differ...

Array methods are eager. Iterator helpers are lazy. Here's why that matters.

Every time you chain .filter() and .map() on an array, JavaScript creates two new arrays. For small lists this is invisible. For a large dataset, a generator producing values on demand, or a stream where you only need the first handful of results, you've materialized thousands of elements you immediately discard. Iterator helpers are the lazy alternative. They shipped natively in Chrome 122, Fire...
