Amazon CloudWatch now natively supports OpenTelemetry metrics. You can send metrics via the OpenTelemetry Protocol (OTLP) and query them using Prometheus Query Language (PromQL), with per-GB ingestion pricing and 15 months of storage included. This allows you to consolidate custom application metrics and AWS vended metrics from more than 70 services in a single solution, queryable together in PromQL. CloudWatch exposes a Prometheus-compatible query API, so teams already using OpenTelemetry, P... Read more ›

Executive Summary: To eliminate race conditions in a high-concurrency ticketing system, I implemented PostgreSQL's FOR UPDATE clause for row-level database locking alongside Go worker channels for in-memory queue serialization. This approach completely prevents inventory over-selling by guaranteeing singular data mutation execution even under flash-sale load. If you have ever built an application that handles live event ticketing, flash sales, or limited-inventory drops, you know the dread of... Read more ›

Built on for PostgreSQL SQL and PL/pgSQL. Point your editor at it for .sql files and get diagnostics, navigation, completion, and formatting backed by real PostgreSQL grammar rather than regex heuristics. Features Diagnostics — Parse errors from tree-sitter reported as LSP diagnostics Semantic Tokens — Syntax highlighting via semantic token classification Document Symbols — Outline of DDL statements (tables, functions, views, etc.) Workspace Symbols — Search across all open files Go to Defini...

We used to have a background job that would take minutes to finish. Not "minutes" as in "go grab a coffee" — minutes as in: the user would kick something off, walk away, and start wondering if it was broken before finally sending a message to engineering. The job processed large sets of data, and the bigger the input got, the longer it took to finish. We cut this job’s runtime by roughly 80% with a change that, in hindsight, was almost embarrassingly small, but would have been hard to find by... Read more ›

Distributed systems handle adversarial nodes through redundancy, which imposes a significant performance overhead. In blockchain systems, Byzantine fault-tolerant state-machine replication (BFT-SMR) is the replicated service that totally orders client transactions before execution. While prior research has primarily focused on designing novel consensus algorithms with improved performance, recent studies have shown that further gains can be achi... Read more ›
A short learning path from a weekend project: I indexed my personal markdown notes (~800 chunks), tried a few local embedding models, stored the same vectors in four different backends, and wired up simple RAG. Not a production guide — just the basics, with honest results from a corpus small enough to reason about. The idea, without the jargon pile Keyword search looks for shared words. Vector search converts text into a list of numbers (an embedding), treats that list as a point in space, an... Read more ›
Hi! Well, well, well. This week we’ve got the U.S. government deciding that some AI models are just too good to share globally, over 86,000 Fortinet devices getting absolutely dunked on by credential-wielding attackers, and - get this - Project Valhalla finally shipped after what feels like a decade of waiting. Plus Spring Boot 4.1 landed with some shiny new toys, and the observability world is collectively deciding that self-hosted Prometheus is getting too expensive to maintain. Let me grab... Read more ›
Writing state machines gets a bit of a bad reputation because they are often implemented in complex manners which are specific to the problem domain. I think that makes people shy away from writing them when they are truly beneficial, including myself. Where they often go awry is when you have some sort of work … Continue reading Asynchronous State Machines with Fibers Read more ›

This release brings Load Test Schedules — a long-requested feature that lets you run a load test automatically at specific times, so you no longer need to kick it off manually. We've also extended the Container Spec file, which now supports more standard Kubernetes settings and gives you the flexibility to pass secrets and other arguments via environment variables. Highlights: • ⏰ Scheduled load test execution • ☸️ Enhanced Kubernetes Container Spec support • 🔐 More flexible auth configuratio... Read more ›
