The design of the Willow Cove processor core is based on Sunny Cove—the first Intel core with a truly new core design in the last 5 years. However, Sunny Cove is only implemented in 10nm Ice Lake processors, while Willow Cove cores are expected to appear in Tiger Lake CPUs (10nm+ process). The mass production of Intel's 10nm chips has been delayed until the end of 2020, […]
The issue of security is critically important for every company dealing with data. Modern tools allow attackers to effectively mimic the activities of a regular user. However, protective mechanisms do not always recognize and prevent unauthorized access attempts. As a result, there are information leaks, theft of funds from bank accounts, and other troubles. A solution to this problem was proposed by the Spanish company Buguroo, which utilizes deep learning […]
Greetings! Eventually, every enterprise finds itself in sudden need of remote access. The necessity to organize remote access to their networks is something nearly every IT professional encounters. Like many, I felt this need hit me with the urgency of “yesterday.” After analyzing all the pros and cons, as well as sifting through tons of information and delving a bit into the theory, I decided to start the installation. […]
Real articles are born from emails to Tucha's technical support. Recently, a client reached out asking for clarification on what happens during connections inside a VPN tunnel between the user's office and the cloud environment, as well as during connections outside the VPN tunnel. Therefore, the entire text provided below is a real email we sent to one of our clients in response to […]
Winter Is Coming. Programmable Logic Controllers (PLCs) are gradually being replaced by embedded personal computers. This is due to the fact that the computing power allows a single device to encompass the functions of a programmable controller, server, and (if the device has an HDMI output) an automated workstation for the operator. In total: a web server, OPC component, database, and automated workstation in a single case, and […]
Next time you find yourself at the station, take a moment to focus on the inscription right in the middle at the bottom of the train car that will take you away on another long-awaited vacation. This inscription is not there by chance; it tells us the mysterious, conditional number of the brake air distributor that is installed on this car. The inscription is visible even if the train is stopped […]
Table of Contents 1. Technical Specifications 2. Hardware and Software 3. Reading Books and Documents 4. Additional Features 5. Autonomy 6. Conclusions and Summaries What is the most important for e-books (readers) with production-technical application? Perhaps, the processor power, memory size, screen resolution? All of this is certainly important; but the most crucial factor is the physical screen size: the larger it is […]
Experts from Qualys Labs discovered several security issues related to the possibility of fooling the programs responsible for password verification mechanisms used in BSD (similar to PAM). The trick lies in passing the username "-schallenge" or "-schallenge:passwd", which is then interpreted not as a username but as an option. After that, the system accepts any password. Vulnerable, i.e., ultimately allowing unauthorized access, […]
The release of the Elementary OS 5.1 "Hera" distribution has been announced, positioned as a fast, open, and privacy-respecting alternative to Windows and macOS. The project focuses on quality design aimed at creating a user-friendly system that consumes minimal resources while providing high boot speed. Users are offered the custom Pantheon desktop environment. Bootable ISO images (1.47 GB) are prepared for download, […]
The HackerOne platform, which enables security researchers to inform developers about detected vulnerabilities and receive rewards for them, has reported an incident of its own hacking. One of the researchers was able to access the account of a security analyst at HackerOne, who had the ability to view confidential materials, including information about vulnerabilities that have not yet been resolved. Since the platform's inception, […]
Qualys identified four vulnerabilities in OpenBSD, one of which allows remote access without authentication to certain network services, while the other three enable privilege escalation. The report notes the quick response of OpenBSD developers — all issues were addressed in OpenBSD 6.5 and OpenBSD 6.6 within 40 hours after private notification. The remotely exploitable […]
My main job mostly consists of software system deployment, which means I spend a lot of time trying to answer questions like: The developer says this software works, but it doesn't for me. Why? Yesterday this software worked for me, but today it doesn't. Why? This is a kind of debugging that's a bit different from regular software debugging. […]
