In this simple tutorial, we will create a couple of microservices using Spring Boot and organize their interaction via the Axon framework. Let's consider the following task: there is a source of trades from the stock market. This source provides us with trades through a REST interface. We need to retrieve these trades, store them in a database, and create a convenient in-memory storage. This storage should perform […]
Configuring data storage for applications running in a Kubernetes cluster can be done in several ways. Some of these methods are already outdated, while others have emerged very recently. In this article, we will discuss the concept of three types of storage connectivity options, including the latest one — connecting via the Container Storage Interface. Method 1: Specifying a PV in the pod manifest A typical manifest describing a pod in a Kubernetes cluster: Color […]
TL;DR: You can now run Kubernetes on Google’s Confidential VMs. Google announced the expansion of its product line with the launch of a new service at the Cloud Next OnAir event on September 8, 2020. Confidential GKE nodes add more secrecy to workloads running in Kubernetes. In July, the first product named Confidential VMs was launched, and today these virtual machines […]
When plasma televisions left the stage, there was a period dominated by liquid crystal panels. However, the era of low contrast is not endless — TVs with elements that emit light on their own without requiring separate lamps are gradually finding their places. This refers to organic light-emitting diode panels. Today, they are not surprising anyone in small diagonal screens — in […]

Regardless of what a company does, DNS security should be an integral part of its security strategy. Name resolution services, which convert network node names to IP addresses, are used by virtually all applications and services on the network. If an attacker gains control over an organization’s DNS, they can easily: take over management of publicly accessible resources and redirect incoming […]

In 2016, Microsoft introduced a new technology to the IT community, WSL (Windows Subsystem for Linux), which aimed at uniting previously irreconcilable competitors fighting for popularity […]
The code that provided the ability to scroll text backward (CONFIG_VGACON_SOFT_SCROLLBACK) has been removed from the text console implementation that comes with the Linux kernel. The code was removed due to errors that had no one to fix because there was no maintainer overseeing the vgacon development. In the summer, a vulnerability (CVE-2020-14331) was discovered and fixed in vgacon, capable of causing a buffer overflow due to inadequate memory availability checks […]
