A group of researchers from Virginia Tech, along with Cyentia and RAND companies, published the results of an analysis of risks when applying various vulnerability remediation strategies. By examining 76,000 vulnerabilities identified from 2009 to 2018, it was found that only 4,183 of them (5.5%) were used to conduct actual attacks. This figure is five times higher than previously published forecasts, in […]
The developers of the distributed database CockroachDB announced the transition of the project's source code to a combination of Business Source License (BSL) and Cockroach Community License (CCL), which is not open-source due to discrimination against certain categories of users. The BSL license was proposed three years ago by the co-founders of MySQL as an alternative to the Open Core model. The essence of BSL is that the code for extended functionality is initially […]
Photo from the author's collection 1. Bubble memory, or memory on cylindrical magnetic domains, is non-volatile memory developed at Bell Labs in 1967 by Andrew Bobeck. Research has shown that small cylindrical magnetic domains form in single-crystal thin films of ferrites and garnets when a sufficiently strong magnetic field is applied perpendicular to the film surface. By changing the magnetic field, […]
Although management, economics, and law have long remained at the top of the training directions in universities, the prestige of IT specialties has also noticeably increased recently. The question arises for prospective students and their parents: which university to enter and what specialty to choose? Is higher education necessary in IT at all? I don't even want to raise this topic — there’s so much discussion on this issue […]
So, over roughly a year (May 2017 – February 2018), I, a C++ programmer, finally found a job in Europe. I applied to dozens of positions in England, Ireland, Sweden, the Netherlands, and even Portugal. I had about twenty conversations over the phone, via Skype, and other video communication systems with recruiters, and a few less with technical specialists. I traveled to […]
A new version of the Tor Browser 8.5.1, focused on ensuring anonymity, security, and privacy, is now available. The browser is centered on providing anonymity, security, and privacy; all traffic is routed only through the Tor network. Direct access via the current system's standard network connection is impossible, making it impossible to track the user's real IP (in the event of a browser exploit, attackers may gain access to system […]
Overview of the key components of the "Autonomous Logistics Information System" (ALIS) for the unified strike fighter F-35. A detailed analysis of the "combat application support block" and its four key components: 1) human-system interface, 2) execution-control system, 3) onboard immunity system, 4) avionics system. Some information about the software and hardware of the F-35 fighter and the tools used for its onboard software. A comparison is provided […]
Welcome to the world of switches! Today, we're going to talk about switches. Imagine you're a network administrator at a new company. A manager approaches you with a "box-fresh" switch and asks you to set it up. You might have thought that they were referring to a regular electrical switch (in English, the word switch refers to both a network switch and an electrical […]
After seven months of development, the release of the earlyoom 1.3 background process has been published. This process periodically checks the amount of available memory (MemAvailable, SwapFree) and attempts to respond early to occurrences of memory shortage. If the amount of available memory falls below a set threshold, earlyoom will forcibly terminate the process that is consuming the most memory (with the highest value in /proc/*/oom_score) via sending SIGTERM or SIGKILL […]
This is a story for those whose only similarity with Einstein is the mess on their desk. The photo of the great physicist's workspace was taken a few hours after his death on April 28, 1955, in Princeton, New Jersey. The Myth of the Master All culture created by mankind is based on archetypes. Ancient Greek myths, great novels, 'Game of Thrones'—they are all the same […]
An article from the Stitch Fix team advocates for the use of non-inferiority trials in marketing and product A/B tests. This approach is indeed applicable when testing a new solution with benefits that are immeasurable through testing. The simplest example is cost reduction. For instance, we automate the process of scheduling the first lesson but do not want to significantly drop overall conversion. Or we are testing […]
Unity Technologies has announced the formation of a preliminary release of the Unity Editor for creating games on GNU/Linux. This release has been formed following several years of unofficial experimental builds. The company now plans to provide official support for Linux. It is noted that the range of supported operating systems is expanding due to the increasing demand for Unity in various fields, from the gaming and film industry to automotive manufacturing […]
