I wrote about the Zelenograd company "Telesystems," which produces the world's smallest voice recorders, back in the distant year of 2010; at that time, "Telesystems" even organized a small tour for us at their production facility. The Weeny A110 recorder from the new Weeny/Dime line measures 29x24 mm, weighs 4 grams, and is 4 mm thick. Additionally, the Weeny line also includes even thinner […]
At the beginning of September, the developers of the Exim mail server informed users about a critical vulnerability (CVE-2019-15846) that allows a local or remote attacker to execute their code on the server with root privileges. Exim users were advised to install an emergency update to version 4.92.2. On September 29, another emergency release, Exim 4.92.3, was published, addressing another critical vulnerability (CVE-2019-16928) that allows […]
The evolution of technology has significantly impacted access control system architecture. By tracing its development, we can predict what awaits us in the near future. The Past Long ago, computer networks were still quite rare. The early access control systems were structured as follows: a master controller serviced a limited number of controllers, while a computer acted as a terminal for its programming and display […]
Istio is a convenient tool for connecting, securing, and monitoring distributed applications. Istio employs various technologies for large-scale software deployment and management, including containers for packaging application code and dependencies for deployment, and Kubernetes for managing these containers. Therefore, to work with Istio, you need to understand how an application with multiple services operates […]
A vulnerability (CVE-2019-16729) has been identified in the pam-python PAM module, which allows connecting authentication modules in Python. If the vulnerable version of pam-python (which is not installed by default) is used, a local user can gain root access by manipulating the default environment variables processed in Python (for example, they can initiate saving a file with […]
Microsoft has launched its Windows Virtual Desktop (WVD) service, which allows users to literally run Windows on an Azure virtual machine. The concept of a 'virtual desktop' essentially progresses the trendy notion of streaming gaming and video services, where the client merely needs a low-powered terminal and internet access. The project is noted to have launched globally.
The release of strace 5.3 has been presented, a utility for diagnosing and debugging programs for operating systems that use the Linux kernel. The utility allows tracking and, starting from version 4.15, intervening in the interaction between the program and the kernel, including the system calls being made, signals generated, and changes in process state. Strace utilizes the ptrace mechanism for its operations. Starting from version 4.13, the release generation of the program has been synchronized.
Linus Torvalds has accepted a set of 'lockdown' patches into the upcoming release of the Linux kernel 5.4, proposed by David Howells (working at Red Hat) and Matthew Garrett (working at Google) to restrict root user access to the kernel. The functionality associated with 'lockdown' has been moved to an optionally loadable LSM module (Linux Security Module), which establishes a barrier between UID 0 and.
The release of the Nextcloud 17 cloud platform has been announced, evolving as a fork of the ownCloud project, created by the main developers of this system. Nextcloud and ownCloud allow deployment of a full cloud storage system on their server systems with support for synchronization and data sharing, as well as offering accompanying features such as tools for video conferencing, messaging, and, starting from the current release, integration of functions for.
The release of Milton 1.9.0 has occurred, a drawing program for an infinite canvas oriented towards computer artists. Milton is written in C++ and Lua, licensed under GPLv3. It uses SDL and OpenGL for rendering. Binary builds are available for Windows x64. Despite the presence of build scripts for Linux and MacOS, there is no official support for these systems. If you want to compile it on your own, it may be.
Hello, readers of Habr. In this article, we are launching a series that will tell you about our developed hyper-converged system AERODISK vAIR. Initially, we wanted to cover everything in the first article, but the system is quite complex, so we'll tackle it piece by piece. We'll start with the story of how the system was created, dive into the ARDFS file system, which is the foundation of vAIR, and also […]
In 2019, the Arkhangelskoye estate museum celebrated its 100th anniversary, during which extensive restoration work was carried out. A reliable Wi-Fi network was implemented in the park so that art enthusiasts could ask Alice about what they see and what the artist intended, while couples on benches could post selfies between kisses. Couples really love this park and buy tickets, but with each […]
