Hello, Habr! In October, OTUS is launching a new stream of the "Linux Security" course. As we approach the course start, we are sharing an article written by one of our instructors — Alexander Kolesnikov. 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 […]

After a while, my article was deleted. I was initially upset, but in the discussion, I was invited to another small […]
The proposed information environment is a kind of decentralized social network. However, unlike many existing solutions, this environment has a number of useful features beyond decentralization and is built on fairly simple and standard technical solutions (email, json, text files, and a bit of blockchain). This allows anyone with basic programming knowledge to create their services for this […]

The Reward by Tohad At the beginning of working with Kubernetes, it is often forgotten to configure container resources. At this stage, it's sufficient to ensure that the Docker image runs and can be deployed in the Kubernetes cluster. However, later, the application needs to be deployed in the production cluster along with other applications. For this, it is necessary to allocate resources for the container and ensure that there are enough of them […]
Hello. I've decided to share my findings—a product of reflection, trials, and errors. Essentially, this is not really a finding, of course—this should already be well known to those dealing with applied statistical data processing and optimization of various systems, not necessarily just DBMS. And yes, they know and write interesting articles based on their research, for example (UPD.: in the comments […]
The Qbs 1.17 build tool release has been announced. This is the fourth release after Qt Company stepped away from developing the project, prepared by a community interested in continuing Qbs development. Qt is required as a dependency for building Qbs, although Qbs itself is designed to facilitate the building of any projects. Qbs uses a simplified version of the QML language to define build scripts, allowing […]
