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 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 […]
