We are excited to announce that Dynatrace has introduced new capabilities for Kubernetes security posture management. This solution provides continuous assessment of adherence to technical standards, visibility, prioritization, and remediation for misconfigurations and compliance findings across Kubernetes environments. Why manual audits and custom scripts fall short for Kubernetes security posture management In the dynamic and complex world of Kubernetes, relying on manual audits, custom script
Migrating from Amazon RDS to DynamoDB can be a significant challenge, especially when transitioning from a relational database like RDS (PostgreSQL, MySQL, etc.) to DynamoDB, a NoSQL, key-value store. One of the most effective strategies for migrating data incrementally is the Dual Write approach. This allows you to keep both databases in sync during the transition, minimizing downtime and reducing the risk of data inconsistency.

This blog post explains the cause of “ERROR 1412 (HY000): Table definition has changed, please retry transaction” with the specific Isolation level settings. Background As per the MySQL documentation, this error should occur for “operations that make a temporary copy of the original table and delete the original table when the temporary copy is built.
Since founding csswizardry.com in 2007, I’ve shared hundreds of articles , tips, tricks, techniques, snippets, and more— all for free. These have ranged from simple one-liners to concepts that have shaped the way thousands of developers approach their work. This freemium model has been the cornerstone of my consultancy business for the last 11 years, and as someone who learned to code from freely available resources, I’m deeply committed to keeping this knowledge accessible to everyone.
Alibabas latest model, QwQ-32B-Preview , has gained some impressive reviews for its reasoning abilities. Like OpenAIs GPT-4 o1, 1 its training has emphasized reasoning rather than just reproducing language. That seemed like something worth testing outor at least playing around withso when I heard that it very quickly became available in Ollama and wasnt too large to run on a moderately well-equipped laptop, I downloaded QwQ and tried it out.

In this series, MySQL with Diagrams, Ill use diagrams to explain internals, architectures, and structures as detailed as possible. In basic terms, here’s how replication works: the transactions are written into a binary log on the source side, carried into the replica, and applied.
Two weeks ago, Bjarne and I and lots of ISO committee members had a blast at the code::dive C++ conference held on November 25, just two days after the end of the Wrocaw ISO C++ meeting. Thanks again to Nokia for hosting the ISO meeting, and for inviting us all to speak at their conference! My talk was an updated-and-shortened version of my CppCon keynote (which I also gave at Meeting C++; I’ll post a link to that video too once it’s posted): If you already saw the CppCon talk, you c
The rise of service-oriented architecture (SOA) and microservices architecture has led to a major shift in software development, enabling the creation of complex, distributed systems composed of independent, loosely coupled services. These architectures offer numerous benefits, including scalability, flexibility, and resilience. However, the distributed nature of these systems introduces new challenges related to understanding, managing, and analysing their behaviour.
DevOps and security teams managing today’s multicloud architectures and cloud-native applications are facing an avalanche of data. On average, organizations use 10 different tools to monitor applications, infrastructure, and user experiences across these environments. Such fragmented approaches fall short of giving teams the insights they need to run IT and site reliability engineering operations effectively.
AWS EC2 Autoscaling is frequently regarded as the ideal solution for managing fluctuating workloads. It offers automatic adjustments of computing resources in response to demand, theoretically removing the necessity for manual involvement. Nevertheless, depending exclusively on EC2 Autoscaling can result in inefficiencies, overspending, and performance issues.
Edge computing has transformed how businesses and industries process and manage data. By bringing computation closer to the data source, edge-based deployments reduce latency, enhance real-time capabilities, and optimize network bandwidth. However, as organizations accelerate their adoption of edge technologies, things are getting more difficult in the form of security, bottlenecks, and more. 2025 portends to be the year these difficulties come to a head.
As organizations turn to the cloud for more and more products and services, many are discovering that the majority of these offerings come with hidden, yet significant, costs.
We've entered an era of unprecedented societal challenges and rapid technological advancements. Harnessing technology for good has become both an ethical imperative and a profitable endeavor.

A recent research from Washington University in St. Louis and Uber Technologies reveals a critical but often overlooked phenomenon in microservices architectures: non-fatal errors. While these errors don’t cause system failures, they introduce significant performance overhead that can impact user experience and operational costs. Study by Lee et. al explores how prevalent are non-fatal errors and what impact do they have on the exposed latency of top-level requests?
As cloud complexity increases and security concerns mount, organizations need log analytics to discover and investigate issues and gain critical business intelligence.
