There are many articles on Habr about how to independently study English. But here's the question: how do you assess your level when learning on your own? It's clear that there are IELTS and TOEFL, but almost no one takes these tests without additional preparation, and these tests, as they say, evaluate not so much the level of language proficiency, but rather the ability to pass […]
The dynamic loader ld.so, included in OpenBSD, under certain conditions may leave the LD_LIBRARY_PATH environment variable for SUID/SGID applications, thus allowing third-party code to be loaded in the context of a process running with elevated privileges. Patches fixing this vulnerability are available for versions 6.5 and 6.6. Binary patches (syspatch) for amd64, i386, and arm64 platforms have already been released into production and […]
Google has released version 79 of the Chrome web browser. At the same time, a stable release of the free project Chromium, which serves as the foundation for Chrome, is available. The Chrome browser is distinguished by its use of Google logos, a crash notification system, the ability to load the Flash module on demand, modules for playing protected video content (DRM), an automatic update system, and RLZ parameters transmission during searches. The next version, Chrome 80 […]
After a year of development, Oracle has released VirtualBox 6.1, a virtualization system. The installation packages are available for Linux (Ubuntu, Fedora, openSUSE, Debian, SLES, RHEL for AMD64 architecture), Solaris, macOS, and Windows. Key changes include: Support for hardware features introduced in the fifth generation of Intel Core i processors (Broadwell) for nested virtualization; removal of the old […]
Developers from Quantic Dream have released a free demo version of the game Detroit: Become Human on the Epic Games Store. This allows interested players to try the new title on their own hardware before purchasing, as David Cage's studio recently revealed the system requirements for the computer port of the game — they turned out to be quite high for interactive cinema. You can try the free demo of Detroit: Become Human right now by downloading […]
Intel appears to have not yet introduced all of its mobile Comet Lake-U processors. A record of testing the Google Hatch system with the unreleased Core i7-10610U processor was discovered in the Geekbench 5 performance testing database. This processor features four cores and eight threads. The test indicated a base frequency of 4.9 GHz, but it is much more likely that […]
CodeWeavers has released Crossover 19.0, a package based on Wine's code that allows you to run applications and games written for the Windows platform. CodeWeavers is one of the key contributors to the Wine project, sponsoring its development and contributing innovations made for its commercial products back to the project. The source code for the open components of Crossover 19.0 can be downloaded from this page. […]
Canonical has released server builds of Ubuntu 19.10.1 for Raspberry Pi devices. The 32-bit builds are available for Raspberry Pi 2, 3, and 4, while the 64-bit builds are for Raspberry Pi 3 and 4. In the proposed builds, the support for USB on Raspberry Pi 4 boards with 4GB of RAM has been made operational (previously, due to a kernel bug, it was supported only […]
Attention! This article is not technical and is intended for readers interested in ethical hacking and learning in this area. If you are not interested in learning, this material is likely not for you. Penetration testing is the process of legally hacking information systems to identify vulnerabilities. A pentest (that is, penetration testing) takes place […]
The release of the proprietary archiver RAR version 5.80 has occurred. Changes in the console version include: You can preserve the last access time of archived files using the -tsp option in the command line. This option can be combined with other options -ts, for example: rar a -tsc -tsp archive files. In the same -ts option, multiple modifiers can be combined. For example, -tscap can be used […]
The technical director of AMD claims that the company has not expressed any intentions to implement support for four threads on one core in future processors. The idea of SMT4 is not so premature — much in this area depends on the availability of software capable of realizing the advantages of multithreading in such a variant. For example, IBM has long offered server processors supporting such a number […]
The purpose of this article is to support beginner data scientists. In the previous article, we explained three ways to solve the linear regression equation: analytical solution, gradient descent, and stochastic gradient descent. For the analytical solution, we applied a formula. In this article, as indicated by the title, we will justify the use of this formula or, in other words, derive it ourselves. Why does it have […]
