Understanding Apache Kafka Performance: Diskless Topics Deep Dive

Diskless topics reward high-throughput workloads with large batches but can struggle with low-throughput patterns. Note: This analysis is based on testing with Diskless Kafka 4.0.0-rc15. Diskless topics are available for you to start experimenting with via the Inkless fork but the feature is still in development, and performance characteristics may change significantly as the technology matures. If you're: This post is for you!

Autoscaling Made Easy with Rancher Cluster API

Kubernetes has revolutionized application deployment and management. However, manually adjusting cluster sizes to meet fluctuating workloads, without constantly under- or over-provisioning resources, quickly drains platform teams’ time and energy. While traditional cloud provider autoscaling tools are functional, they often fall short when it comes to truly dynamic, Kubernetes-aware scaling, especially in a world with diverse infrastructure.

Semantic Caching: What We Measured, Why It Matters

Semantic caching promises to make AI systems faster and cheaper by reducing duplicate calls to large language models (LLMs). But what happens when it doesn’t work as expected? We built a test environment to find out. Through a caching system, we evaluated how semantically similar queries would behave. When the cache worked, response times were fast. When it didn’t, things got expensive. In fact, a single semantic cache miss increased latency by more than 2.5x.

SentinelOne outage: July 10 incident went unacknowledged

July 10, 2025, SentinelOne, a leading cybersecurity platform, experienced a widespread outage that disrupted access to its admin consoles across multiple regions. The incident impacted users in Europe, North America, and beyond, preventing security teams from accessing critical management features. Despite the scale of the disruption, no official public acknowledgment or status update was issued by SentinelOne.

Google Workspace outage: July 18, 2025

Google Workspace went down again in July 2025—but if you had asked AI tools like Google’s own AI Overviews, ChatGPT, or Claude, you would have been told everything was fine. Every one of these tools incorrectly claimed that services were up and running while users across the globe were unable to connect, send messages, or even log in.

Confessions of a CTO: How we Tamed our Cloud Costs

If you’ve ever found yourself staring at a cloud bill that could buy a small island or at least a very nice car, you're not alone. Believe me, at Cribl, we've had our share of those "molotov cocktail" bills that make our CFO, Zach, look like he's about to spontaneously combust. And yeah, a few F-bombs might have dropped from various senior leaders (myself included, I won't lie).

Release Management: Process Steps, Tools & Best Practices for ITSM

Software delivery can derail quickly without structure. Version mismatches, failed rollbacks, broken features, these are often symptoms of a weak or unclear release management process. Release management brings order to the chaos by defining how features, bug fixes, and system updates move from development to production. It sets expectations, aligns timelines, and reduces deployment risk.

Why Entrepreneurs Sink: Common Legal Woes

What No One Ever Tells You About Running a Franchise

Everyone talks about starting a business from scratch, building your own brand, and hustling your way to the top. Be it something like a restaurant, a retail, well, just anything really. But what about the folks running businesses that already exist, just not under their name? Well, yeah, it's honestly a fair question, but owning a franchise is its own kind of beast. It's structured, familiar, and yes, a little safer than going rogue with your own idea, but it's far from effortless. If anything, it's like being handed the keys to someone else's house and being told to turn it into a home.
