Not long ago, I faced a rather unconventional task of setting up routing for MetalLB. All would be fine since usually, no additional actions are required for MetalLB, but in our case, there is quite a large cluster with a rather simple network configuration. In this article, I will explain how to configure source-based and policy-based routing for your cluster's external network. I […]
Bitdefender Labs, a software security research company, has revealed details about a new malware targeting Android devices. According to experts, it behaves somewhat differently than most common threats, as it does not attack all devices. Instead, the virus selects users from whom it can extract the most useful data. The malware developers have restricted it from attacking users in certain […]
Micron has introduced two new series of M.2 solid-state drives with a PCIe 3.0 x4 interface: Micron 2210 and Micron 2300. These new products are positioned as affordable storage devices for consumer laptops and desktops. The more budget-friendly Micron 2210 series is built on 3D QLC NAND memory chips, which allow storage of four bits of information in one […]
Five vulnerabilities have been fixed in FreeBSD, including issues that could potentially lead to data overwriting at the kernel level when certain network packets are sent, or could allow a local user to escalate their privileges. The vulnerabilities have been patched in updates 12.1-RELEASE-p5 and 11.3-RELEASE-p9. The most critical vulnerability (CVE-2020-7454) was caused by a lack of proper packet size checking in the libalias library when parsing protocol-specific […]
After two years of development, the first major release of Deno 1.0 has been unveiled, a platform for executing applications in isolation using JavaScript and TypeScript, which can be used for creating server-side handlers. The platform is being developed by Ryan Dahl, the creator of Node.js. Like Node.js, Deno uses the V8 JavaScript engine, which is also used in Chromium-based browsers. […]
Automating web application testing with Selenium is a common solution among test developers, and C# is one of the most popular programming languages, so the combination of these tools is not surprising. For development using these technologies, popular proprietary software from Microsoft for Windows is often employed; however, I was curious to learn about which free alternatives could be used without straying from the […]
Source Contrary to popular belief, access control systems on their own rarely solve security issues. In reality, ACS provides opportunities to address such problems. When you approach the selection of an ACS from the perspective of an all-in-one security package that will completely mitigate the company's risks, challenges are inevitable. Moreover, complex issues will only become apparent after the system is deployed. At first […]

The main innovation concerns support for the AMD Ryzen 4000 processor series. Regarding Intel processors, it is reported […]
Synopsys analyzed 1,253 commercial codebases and concluded that almost all (99%) of the examined commercial applications contain at least one component with open-source code, and 70% of the code in the reviewed repositories is open. In comparison, in a similar study from 2015, the proportion of open source was 36%. In most cases, the third-party open-source […]
After six months of development, the release of the user environment Cinnamon 4.6 has been formed, within which the Linux Mint distribution community is developing a fork of the GNOME Shell desktop, the Nautilus file manager, and the Mutter window manager, aimed at providing a classic GNOME 2 style environment with successful interaction elements from GNOME Shell. Cinnamon is based on GNOME components, but these components […]
DevOps engineers are multidisciplinary specialists who automate processes and understand how developers, QA, and managers operate. They can program, quickly learn complex tools, and do not shy away from unfamiliar tasks. There are few DevOps engineers, and they command salaries of 200,000 to 300,000 rubles, yet there are still many job openings. Dmitry Kuzmin explains what DevOps engineers specifically do and what is required […]
Almost every successful business application eventually reaches a stage where horizontal scaling is necessary. In many cases, you can simply launch a new instance and reduce the average load. However, there are less trivial situations where we must ensure that different nodes are aware of each other and carefully distribute the workload. Fortunately, it turns out that Erlang, which we […]
