Kubernetes has become the de facto standard for container orchestration, enabling organizations to build, deploy, and scale modern applications with efficiency and agility. As more organizations adopt Kubernetes, the need for proper security and management of sensitive data within these environments becomes paramount. One crucial aspect of ensuring a secure Kubernetes infrastructure is the effective management of secrets, such as API keys, passwords, and tokens.

With the launch of ChatGPT, an AI chatbot developed by OpenAI, in November 2022, large language models (LLMs) and generative AI have become a global sensation, making their way to the top of boardroom agendas and household discussions worldwide. GPT (generative pre-trained transformer) technology and the LLM-based AI systems that drive it have huge implications and potential advantages for many tasks, from improving customer service to increasing employee productivity.

I have seen many Linux Performance engineers looking at the “IOWait” portion of CPU usage as something to indicate whenever the system is I/O-bound. In this blog post, I will explain why this approach is unreliable and what better indicators you can use. Let’s start by running a little experiment – generating heavy I/O usage on the system: sysbench --threads=8 --time=0 --max-requests=0 fileio --file-num=1 --file-total-size=10G --file-io-mode=sync --file-extra-flags=direct

Log forensics—investigating security incidents based on log data—has become more challenging as organizations adopt cloud-native technologies. Organizations are increasingly turning to these cloud environments to stay competitive, remain agile, and grow. But as organizations rely more on cloud environments, data and complexity have proliferated. Teams struggle to maintain control of and gain visibility into all the applications, microservices and data dependencies these environments generate.

Historically MySQL is great in horizontal READ scale. The scaling, in that case, is offered by the different number of Replica nodes, no matter if using standard asynchronous replication or synchronous replication. However, those solutions do not offer the same level of scaling for writes operation. Why? Because the solutions still rely on writing in one single node that works as Primary.

Many organizations today are utilizing Kubernetes to orchestrate their containers’ deployment, scaling, and management. The benefits of this approach include faster deployment, easier and more effective management, cost reduction, and more. Because it’s critical that operations teams ensure that all internal resources are available for their users, synthetic monitoring of those resources is important.

It’s hard to ignore the discussion around the Open Letter arguing for a pause in the development of advanced AI systems. Are they dangerous? Will they destroy humanity? Will they condemn all but a few of us to boring, impoverished lives? If these are indeed the dangers we face, pausing AI development for six months is certainly a weak and ineffective preventive.

Time series analysis is a specialized branch of statistics that involves the study of ordered, often temporal data. Its applications span a multitude of fields, including finance, economics, ecology, neuroscience, and physics. Given the temporal dependency of the data, traditional validation techniques such as K-fold cross-validation cannot be applied, thereby necessitating unique methodologies for model training and validation.

As a database administrator, have you ever been in a situation when your database confronted a brute force attack? A brute force attack can be launched against a user account in MySQL. MySQL replies with success or error based on supplied credentials, and the time required for the verification is almost the same in either case. Hence, an attacker can launch a brute force attack against a MySQL user account at a rapid rate and can try many different passwords.

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process.

In simpler terms, logical replication in PostgreSQL is a way to copy data from one database to another in a more flexible and customizable manner compared to physical replication. Instead of copying the entire database, logical replication focuses on replicating changes made to individual rows or transactions. To set up logical replication, you create a publication on the source database and a subscription on the target database.
