In the previous article, we discussed Nemesida WAF Free ā a free tool for protecting websites and APIs from hacking attacks. In this article, we decided to review the popular vulnerability scanner Wapiti. Scanning a website for vulnerabilities is a necessary measure that, together with source code analysis, allows for an assessment of its security level against compromise threats. A scan of the web resource can be performed […]
Note from the translator: As the number of YAML configurations for K8s environments increases, the need for automated validation becomes more relevant. The author of this review not only selected existing solutions for this task but also examined how they work using an example of a Deployment. It turned out to be quite informative for those interested in this topic. TL;DR: The article compares six static validation tools and […]
Many have surely heard of Anycast. With this method of network addressing and routing, a single IP address is assigned to multiple servers in the network. These servers can even be located in data centers that are far apart. The idea of Anycast is that, depending on the location of the request sources, the data is sent to the closest server (according to the network topology, more precisely ā BGP routing protocol). Thus, […]
On July 10, 2020, the Austrian company Proxmox Server Solutions GmbH released a public beta version of its new backup solution. We have already discussed how to use built-in backup methods in Proxmox VE and perform incremental backups with the third-party solution ā VeeamĀ® Backup & Replicationā¢. Now, with the emergence of Proxmox Backup Server (PBS), the backup process should become […]
In one of the previous articles in our series about the Proxmox VE hypervisor, we already explained how to perform backups using built-in tools. Today, we will show how to use the excellent tool VeeamĀ® Backup & Replicationā¢ 10 for the same purpose. "Backups have a clear quantum essence. Until you attempt to restore from a backup, it exists in superposition. It is both successful and unsuccessful at the same time." […]
On July 14, 2020, Vicenza, Italy ā Leading global developer of open-source extensions Zextras released its own version of the popular email server Zimbra with downloads from its own repository and support. Zextras solutions add collaboration, communication, storage support, mobile device management, real-time backup and recovery, and multi-tenant infrastructure administration capabilities to the Zimbra email server. Zimbra is […]
How the Apache & Nginx combination is implemented in Timeweb For many companies, Nginx + Apache + PHP is a very typical and common stack, and Timeweb is no exception. However, understanding how it is implemented can be interesting and useful. The use of such a stack is certainly driven by the needs of our clients. Both Nginx and Apache play a special role, each […]
Often, people entering the field of Data Science have unrealistic expectations about what awaits them. Many believe they will soon be writing amazing neural networks, creating a voice assistant like Iron Man, or beating everyone in financial markets. However, the work of a Data Scientist is heavily data-driven, and one of the most important and time-consuming aspects is […]
A hackathon is a forum for programmers during which specialists from various software development fields collaboratively solve client tasks. This communication tool for both small and large businesses can undoubtedly be called a driver of innovative technologies and fresh digital solutions to the masses. It's important to note that the client, based on their business problems, defines the task for the hackathon, and […]

We now offer an open API interface that provides access to most ZCRM functionalities. The API allows you to utilize the CRM for any sales channels. Below, we briefly describe how to work with the API and the available functionality. We also provide […]
This article's translation has been prepared in anticipation of the launch of the course 'Industrial ML on Big Data.' Distributed learning across multiple high-performance computing instances can reduce the training time of modern deep neural networks on large datasets from weeks to hours or even minutes, making this training technique predominant in practical deep learning applications. Users need to understand how […]
Nowadays, it's hard to imagine a project based on Kubernetes without the ELK stack, which is used to store logs from both applications and system components of the cluster. In our practice, we use the EFK stack with Fluentd instead of Logstash. Fluentd is a modern, versatile log collector that is gaining popularity and has joined the Cloud Native Computing Foundation, which is why […]
