IBM has announced a toolkit for implementing fully homomorphic encryption (FHE) technology for Linux-based operating systems (for IBM Z and x86 architectures). Previously available for macOS and iOS, IBM's FHE toolkit is now released for Linux as well. It is provided in the form of Docker containers for three distributions: CentOS, Fedora, and Ubuntu Linux. What’s special about the technology […]
Currently, blockchains are largely isolated from external information sources — both centralized resources and other blockchains. To ensure different blockchains are compatible and can easily exchange data with one another (and with external resources), oracles can be used. What are oracles? An oracle is a system that retrieves and verifies events from outside the blockchain and transmits this data […]
The profession of a system administrator is always accompanied by stereotypical perceptions. A sysadmin is often seen as a jack-of-all-trades IT specialist in any company who fixes computers, establishes the Internet, handles office equipment, configures software, etc. It has even reached the point where a System Administrator Day has been established — the last Friday in July, which is today. Moreover, the holiday celebrates its anniversary today — the first System Administrator Day was celebrated […]
The translation of this article has been prepared in anticipation of the launch of the course "DevOps Practices and Tools." If you are reading this, you have probably heard something about Kubernetes (and if not, how did you end up here?). But what exactly is Kubernetes? Is it an "Industrial-Grade Container Orchestration"? Or a "Cloud-Native Operating System"? What does this even mean? Honestly, I don't […]
After two months of development, Linus Torvalds has released Linux kernel 5.8. Among the most notable changes are: the KCSAN race condition detector, a universal notification delivery mechanism to user space, support for inline encryption hardware, enhanced protection mechanisms for ARM64, support for the Russian processor Baikal-T1, the ability to separately mount instances of procfs, and the implementation of protection mechanisms for ARM64 such as Shadow Call Stack and BTI. The kernel […]
Bpytop is a system resource monitor that displays current values and statistics for CPU, memory, disks, network, and individual processes. It is written in Python using psutil. This is a port of the bashtop utility to Python. According to the author, it is faster and consumes less CPU by itself. Features: Easy to use, with a menu system similar to […]
Bitdefender has announced the open-sourcing of its Hypervisor Introspection (HVI) technology. It was developed in collaboration with the Xen project. The project's history began in 2015 when the libbdvmi library was introduced for Hypervisor 4.6. This library allowed virtual machines and software that searches for malicious code to be 'friends'. Previously, specialized malware could remain undetected for a long time […]
Recently, colleagues in the field have independently started asking me: how to receive all Bluetooth channels simultaneously from one SDR receiver? The bandwidth allows it, and there are SDRs with an output bandwidth of 80 MHz or more. It is certainly possible to do this on an FPGA, but the development time for such a solution will be quite significant. I have long known that it can be done on […]
System Administrator Day (or rather, the day to recognize their contributions) is a wonderful opportunity to reflect on oneself from an outside perspective. To see oneself and one's work through the eyes of loved ones. The title 'system administrator' sounds quite vague. Sysadmins are responsible for a wide range of different devices, from desktops to servers, printers, and air conditioners. Therefore, when introducing oneself to another IT professional, it's essential to add at least one qualification. For example, […]
A dangerous vulnerability has been discovered in the WordPress plugin wpDiscuz, which is installed on over 80,000 sites. This flaw allows anyone to upload any file to the server without authentication, including PHP files, thereby executing their code on the server. Versions affected are from 7.0.0 to 7.0.4 inclusive. The vulnerability has been fixed in release 7.0.5. The wpDiscuz plugin allows the use of AJAX for […]
After a year and a half of development, the Apache Software Foundation has released Apache Hadoop 3.3.0, a free platform designed for distributed processing of large volumes of data using the map/reduce paradigm, which divides tasks into many smaller, isolated fragments, each of which can be executed on a separate node of the cluster. A Hadoop-based storage can scale across thousands of nodes and […]
An experimental release of the open implementation of WinAPI — Wine 5.14 — has taken place. Since the release of version 5.13, 26 bug reports have been closed and 302 changes made. The most significant changes include: Continued restructuring support for the console. An initial version of the Webdings font has been proposed.
