Messaging applications share a similar set of features, making it difficult for many of them to attract widespread attention. Currently, a few major players dominate the market, such as WhatsApp, Telegram, and Facebook Messenger. Developers of other applications in this category must seek ways to encourage people to use their products. One such […]
The release of the desktop-oriented distribution GhostBSD 19.09 has been presented, built on TrueOS and offering the MATE user environment. By default, GhostBSD uses the OpenRC initialization system and the ZFS file system. Both live mode operation and installation on a hard drive are supported (using its own installer ginstall, written in Python). Boot images are created for the amd64 architecture (2.5 GB). In […]
In the upcoming release and current beta versions of kernel Linux 5.4, support for the Microsoft exFAT file system driver has appeared. However, this driver is based on an older code from Samsung (branch version 1.2.9). In its own smartphones, the company is already using a version of the sdFAT driver based on branch 2.2.0. Now, information has been released that a developer from South Korea, Park Joo Hyun […]
Last week, developers of the popular password manager LastPass released an update that addresses a vulnerability that could lead to the leak of user data. The issue was announced after it was resolved, and users of LastPass were advised to update their password manager to the latest version. The vulnerability allowed attackers to steal data entered by users on the last visited website. […]
It seems that autumn is not a good time for Windows 10 developers. Otherwise, it is hard to explain the fact that nearly a year ago, build 1809 displayed a whole bunch of issues, even after being re-released. This includes incompatibility with older AMD graphics cards, issues with Windows Media search, and even crashes in iCloud. However, it seems that the situation is still […]
In the world of engineering education, there are many excellent courses, but often the training programs built around them have one serious drawback — a lack of good coherence between different topics. One might argue: how is that possible? When forming a curriculum, prerequisites and a clear order of subjects to be studied are specified for each course. For example, in order to gather and [...]
In the past decade, in addition to methods for extracting secrets or performing other unauthorized actions, attackers have started using unintentional data leakage and manipulation of program execution processes through side channels. Traditional attack methods can be costly in terms of knowledge, time, and computational power. Side-channel attacks, on the other hand, may be easier to implement and non-destructive, [...]
Main innovations: The pidfd mechanism, which allows binding a specific PID to a certain process. The binding continues to act even after the process has been terminated, so the PID can be reassigned upon restart. Details. Frequency range restrictions in the process scheduler. For example, critical processes can be launched with a minimum frequency threshold (say, no less than 3 GHz), while low-priority ones can have an upper frequency limit [...]
The vim editor fork – Neovim has finally crossed the version 0.4 milestone. Key changes: Added support for floating windows. Demo. Added support for multigrid. Previously, Neovim had a single grid for all created windows, now they are separate, allowing customization of each: changing font sizes, window styles, and adding individual scrollbars. Introduced 'Nvim-Lua [...]
After two months of development, Linus Torvalds presented the release of Linux kernel 5.3. Among the most notable changes: support for AMD Navi GPUs, Zhaoxi processors, and Intel Speed Select power management technology, the ability to use umwait instructions to wait without using cycles, the 'utilization clamping' mode to enhance interactivity for asymmetric CPUs, the pidfd_open system call, the ability to use IPv4 addresses from the 0.0.0.0/8 subnet, the ability [...]
As part of the Parallel GCC research project, work has begun on adding the capability to GCC that allows the compilation process to be divided into multiple concurrently executing threads. Currently, to increase build speed on multi-core systems, the make utility launches separate compiler processes, each of which compiles an individual source file. The new project experiments with providing […]
Have you ever wondered how many hours, months, and even lives have been wasted on solving the "wrong" problems? Once, some people started complaining about having to wait unbearably long for the elevator. Other people were concerned about these complaints and spent a lot of time, effort, and money trying to improve elevator operation and reduce wait times. But […]
