| Realtime Video AI with Diffusion Models | Demuxed 2025 | 2025-10-29 |
Claims realtime means generating one second of video in under one second and delivering usable frames with only 2–4 denoising steps; latency tests in demo show… | ||
| 5 Levels of High Availability: from Multi-instance to Hybrid Cloud | Conf42 Site Reliability Engineering 2021 | 2021-09-30 |
Titles states the scope but specifics decide: five concrete HA levels are defined and compared, with Hazelcast examples and measured latencies — 5 levels… | ||
| Mutation Testing with PIT | TestCon Europe 2021 | 2021-09-07 |
Links a 1999 Mars failure to weak tests and proposes mutation testing as the concrete fix: run PIT mutation testing, generate mutants (change + to − etc.), and… | ||
| Build Your Kubernetes Operator with the Right Tool! | 4Developers 2021 | 2021-05-24 |
Demo builds a Hazelcast operator that watches a custom resource with one parameter size and adjusts Deployment replicas from 1 to 3 accordingly, implemented… | ||
| Build Your Kubernetes Operator with the Right Tool! | DevOps Pro Europe 2021 | 2021-05-11 |
Walks through building a Hazelcast operator end to end: generate with operator-sdk init and operator-sdk create api, docker build and push, run make install… | ||
| Architectural Caching Patterns for Kubernetes | Conf42 Cloud Native 2021 | 2021-04-29 |
Compares concrete caching topologies on Kubernetes and shows which one to pick by claim and evidence: demoed architectures include Sidecar Caching, Reverse… | ||
| Premiere - Conf42 Enterprise Software 2021 | Conf42 Enterprise Software 2021 | 2021-03-25 |
One videocast bundles ~20 short talks and a live demo: a rookout walkthrough shows rookout non‑breaking breakpoints that collect snapshots without redeploy… | ||
| Mutation Testing with PIT | Conf42 Enterprise Software 2021 | 2021-03-25 |
Explains mutation testing as introducing artificial bugs and checking whether tests kill them, using PIT to generate and report mutants automatically. Shows a… | ||
| Distributed Locking in Kubernetes | Developers Summit 2021 | 2021-02-18 |
Distributed locking in Kubernetes compares concrete implementations: single-instance cache (Hazelcast/Redis) for efficiency only, Hazelcast cluster and Redis… | ||
| Architectural Patterns for Caching Microservices | Developer Summit 2020 | 2020-11-21 |
Compares four concrete caching topologies and when each reduces latency or ops: in-process libraries (Guava, EHCache) give lowest latency but no eviction or… | ||
| Where is my cache? Architectural patterns for caching microservices by example | Voxxed Days Ticino 2019 | 2019-10-09 |
Compares five concrete deployment patterns and their tradeoffs: Embedded distributed with Hazelcast saves network hops but ties data to replicas and JVMs… | ||
| Where Is My Cache? Architectural Patterns for Caching ... | Heapcon 2019 | 2019-10-03 |
Compares five concrete caching patterns and when each actually works: embedded cache (Guava/Ehcache with Spring @Cacheable) for lowest JVM latency but… | ||
