Vulnerability detection and resilience assessment against hacking attacks for smart cards and cryptoprocessors with embedded protection

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, [...]

The Linux kernel 5.3 has been released!

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 [...]

Neovim 0.4.2

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 [...]

Linux kernel release 5.3

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 [...]

Project to add support for parallel compilation processes in GCC

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 […]

The XY Phenomenon: How to Avoid 'Incorrect' Problems

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 […]

Varlink – core interface

Varlink is a core interface and protocol that is easy to read by both humans and machines. The Varlink interface combines traditional UNIX command-line parameters, text formats for STDIN/OUT/ERROR, man pages, service metadata, and is equivalent to file descriptor FD3. Varlink is accessible from any programming environment. The Varlink interface defines the methods that will be implemented and how. Each […]

A new version of the exFAT driver has been proposed for the Linux kernel.

Korean developer Park Ju Hyung, specializing in porting Android firmware for various devices, has introduced a new version of the exFAT file system driver — exfat-linux, which is a fork of the "sdFAT" driver developed by Samsung. Currently, the exFAT driver from Samsung has already been added to the Linux kernel's staging branch, but it is based on the old driver codebase (1.2.9). […]

The alpha version of the new XMPP server Xabber Server has been released

The developers of the XMPP client Xabber have released their own XMPP server based on a fork of ejabberd. The project code is distributed under the AGPLv3 license. Key features of Xabber Server include: Fast installation that allows you to automatically set up the server and configure all the necessary certificates; A new group chat protocol; Editing, deleting, and recalling messages; A quick client synchronization feature; A reliable message delivery protocol; Session management (the ability to log out (revoke the right […]

F9sim 1.0 — Falcon 9 First Stage Simulator

Reddit user u/DavidAGra (David Jorge Aguirre Gracio) has introduced the first version of his own rocket flight simulator – 'F9sim' 1.0. Currently, this is a free simulator written in Delphi using OpenGL technologies, but the project author is considering opening the source code and rewriting the project's code in C++/Qt5. The original goal of the project is to create a realistic 3D simulation of the flight of the first stage of a launch vehicle […]
