The relevance of blocking access to prohibited resources concerns any admin who may officially be accused of failing to comply with laws or orders from relevant authorities. Why reinvent the wheel when there are specialized programs and distributions for our tasks, such as: Zeroshell, pfSense, ClearOS. Another question arose from management: Does the product we use have a security certificate from our country? We had experience […]

This is a fairly common myth in the server hardware industry. In practice, hyper-converged solutions (where everything is in one) are needed for many purposes. Historically, the first architectures were developed by Amazon and Google for their services. The idea at that time was to create a computing farm consisting of identical nodes, each with its own disks. All of this […]
Note from the translator: Lead engineer at Zalando, Henning Jacobs, has repeatedly noticed that Kubernetes users struggle to understand the purpose of liveness and readiness probes, as well as their proper application. Hence, he gathered his thoughts in this concise note, which will eventually become part of the K8s documentation. Health checks, known in Kubernetes as liveness probes (i.e., literally, […]
Information about what KDB+ is, the Q programming language, and their strengths and weaknesses can be found in my previous article and briefly in the introduction. In this article, we will implement a service in Q that will process incoming data streams and compute various aggregate functions in a 'real-time' mode (i.e., it will be able to handle all […]
The architecture development for Zen 3 is already complete, as indicated by AMD representatives at industry events.

Mozilla's developers announced a decision to remove all extensions for integration with search engines that use OpenSearch technology from the Firefox add-ons catalog. It is also reported that support for OpenSearch XML markup in Firefox will be removed in the future, which allowed websites to define scripts for integrating search engines into the browser's search panel. OpenSearch-based add-ons will be removed on December 5.
