Linear probing is one of the simplest and most space-efficient approaches to hash table design, and is widely used in sequential settings due to its compact memory layout. However, designing a concurrent linear-probing hash table with strong liveness guarantees has proved difficult, and only a handful of such algorithms have been proposed, all of which either restrict concurrency or rely on large per-entry metadata, thereby compromising space ef...

Redis Data Structures Every Engineer Should Know- Strings store one value per key. They work for counters, session tokens, and cached payloads.- Hashes store an object's fields under one key. You can update one field without rewriting the rest.- Lists are ordered sequences with fast push and pop at both ends. They fit queues, feeds, and recent-item lists.- Sets hold unique members and support intersection, union, and difference. They cover tagging, follower overlap, and deduplication.- Sorted...

The Cancer Metabolism and Tumor Microenvironment Laboratory at the University of Liège has uncovered a previously unrecognized mechanism that promotes cancer cell survival under therapeutic pressure. Published in MedComm, the study shows how a key enzyme in lipid metabolism, stearoyl-CoA desaturase-1 (SCD1), cooperates with an epigenetic regulator to support tumor growth. Read more ›

How we built an in-process client-side load balancer for a million requests per second of internal fan-out traffic, what we layered on top (N-ring fade-in, occupancy-based bounded load, and AZ-aware routing with a latency health factor), and how hardening that path cut cost and made the service resilient to the infrastructure underneath it.

As system architectures grow increasingly complex, the cloud-native community faces a subtle but pressing challenge: we are drowning in our own telemetry data. It is easier than ever to instrument an application and collect signals, but... Read more ›
In 2011, a team at a mid-sized financial services company spent six weeks hunting a bug that would have been unremarkable except for one property: it disappeared whenever they tried to observe it. The application, a high-throughput order-processing system, would occasionally drop transactions. Not crash. Not log an error. Just quietly lose work, the way a conversation gets interrupted and both people politely pretend the sentence was finished. The bug was intermittent, customer-reported, and ... 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 ›
