One of the fundamental requirements of the Kubernetes networking model is that each pod must have its own IP address, and any other […]
IT environments are becoming increasingly complex. In these conditions, having up-to-date information about the nodes present in the network and subject to processing is critically important for IT automation systems. In Red Hat Ansible Automation Platform, this issue is addressed through so-called inventories — lists of managed nodes. In its simplest form, an inventory is a static file. This is the ideal […]
Today, several major DNS services and DNS server manufacturers will hold a joint event, DNS flag day 2020, aimed at focusing attention on resolving issues with IP fragmentation when processing large DNS messages. This is the second such event; last year's 'DNS flag day' concentrated on the correct handling of EDNS requests.

Hello, Habr! In our work, our company often deals with various static code analysis tools (SAST). Out of the box, they all perform moderately. Of course, it depends on the project and the technologies used in it, as well as how well these technologies are covered by analysis rules. In my opinion, one of the key criteria for choosing a SAST tool […]
