Continuing the series of notes on lesser-known bash functions, I will show you seven variables you might not be aware of. 1) PROMPT_COMMAND You may already know how to manipulate the prompt to display various useful information, but not everyone knows that each time the prompt is displayed, a shell command can be executed. In fact, many complex prompt manipulators […]
We all know that the world of technology is digital or striving to be. Digital broadcasting is not a new phenomenon, but if you haven't been specifically interested in it, the technologies associated with it may come as a surprise. The content of the series of articles Part 1: General architecture of the CATV network Part 2: Composition and form of the signal Part 3: The analog component of the signal […]
The release of the free distribution of OpenIndiana 2019.04 is now available, which has replaced the binary distribution of OpenSolaris, whose development was discontinued by Oracle. OpenIndiana provides users with a working environment built on a fresh snapshot of the Illumos project codebase. The development of OpenSolaris technologies continues through the Illumos project, which enhances the kernel, network stack, file systems, drivers, as well as the basic set of user system utilities […]
The current 14nm manufacturing process will remain in operation at least until 2021. In Intel's presentations about the transition to new technologies, any processors and products are mentioned, but not desktop ones. Mass production of Intel products based on 7nm technology will not begin before 2022. All engineering resources will be shifted from the 14nm process to the 7nm process, and the 10nm process will […]
Once, I discovered a phone number form behind the windshield of my wife's car, which you can see in the photo above. A question arose: why is there a form, but no phone number? The genius answer was: so no one can know my number. Well… "My phone is zero-zero-zero, and don't think that's a password." […]
A new version of the KWin-lowlatency composite manager for KDE Plasma has been released, which includes patches to improve interface responsiveness. Changes in version 5.15.5: New settings have been added (System Settings > Display and Monitor > Compositor) that allow you to balance responsiveness and functionality. Support for NVIDIA graphics cards. Support for linear animation has been disabled (it can be enabled in the settings). Use of glXWaitVideoSync instead of DRM VBlank. […]
You may be wondering — why use Docker here? What’s wrong with accessing the ILO web interface and configuring your server as needed? I thought the same when I was given a couple of old, unused servers that I needed to reinstall (what is called reprovisioning). The servers themselves are located across the ocean, and the only access is the web […]
A long time ago, I decided to demonstrate the reversibility of the process for laughs and learn to generate JavaScript (or rather, Asm.js) from machine code. QEMU was chosen for the experiment, and some time later, an article was written for Habr. In the comments, I was advised to switch the project to WebAssembly, and it was hard for me to abandon a nearly finished project… The work continued, but it was really […]
Today, I want to discuss what 'digital' means. Digital transformation, digital assets, digital products… These terms are everywhere today. In Russia, national programs are being launched, and even ministries are being renamed, but when reading articles and reports, you often come across vague phrases and unclear definitions. Recently, I attended a 'high-level' meeting at work, where representatives from a well-respected […]
A new version of the Russian distribution Astra Linux Common Edition (CE), release "Eagle," has been released. Astra Linux CE is positioned by the developer as a general-purpose OS. The distribution is based on Debian, and it uses its own Fly environment as the graphical interface. Additionally, there are many graphical utilities to simplify system and hardware configuration. The distribution is commercial; however, the CE edition is available […]
"I created OASIS because I felt uncomfortable in the real world. I didn't know how to get along with people. I was afraid my whole life. It wasn’t until I realized that the end was near that I understood that despite how cruel and frightening reality can be, it remains the only place where you can find true happiness. Because reality […]
Several years ago, Fabrice Bellard wrote jslinux — a PC emulator written in JavaScript. After that, there was at least Virtual x86. But as far as I know, they were all interpreters, while Qemu, also written significantly earlier by Fabrice Bellard, and probably any self-respecting modern emulator, uses JIT compilation of guest code into code […]
