LXC (Linux Containers) is an operating system-level virtualization system for running multiple isolated instances of the Linux operating system on a single node.

A new version of the system programming language Nim has been released. It features partial incompatibility with version 1.0, for instance, due to stricter type conversion. However, there is a flag for such cases —useVersion:1.0. The main innovation is a new garbage collector enabled by the —gc:arc option. The language's author, Andreas Rumpf, plans to write a detailed article on the benefits of ARC, but for now, he offers a look at his presentation […]

There are many relatively safe methods for remote work, but given the scale of the problem, a simple solution for all users for connecting to the office remotely without the need for additional configurations is necessary […]
This article describes the implementation of pipelines in Unix. I was somewhat disappointed that a recent article titled ‘How Pipelines Work in Unix?’ was not about the internal structure. It piqued my interest, and I dug into old sources to find the answer. What’s the essence? Pipelines—‘probably the most important invention in Unix’—are a defining characteristic […]
The author of the article, Douglas McIlroy, is an American mathematician, engineer, and programmer. He is best known for developing the pipeline concept in the Unix operating system, principles of component-oriented programming, and several original utilities: spell, diff, sort, join, speak, tr. Sometimes you come across truly remarkable programs. After rummaging through my memory, I compiled a list of true gems of Unix over the years. Mostly, they are quite rare and not […]
In the current climate, more companies are considering how to transition employees to remote work.

Researchers from the Helmholtz Center for Information Security (CISPA), Ohio State University, and New York University conducted a study on hidden functionality in applications for the Android platform. An analysis of 100,000 mobile applications from the Google Play catalog, 20,000 from an alternative catalog (Baidu), and 30,000 pre-installed applications from various smartphones highlighted across 1,000 firmware from SamMobile, revealed that 12,706 (8.5%) […]

Hello, Habr! We want to share with you the statistics we gathered during our fifth global survey. Read on to find out why data loss occurs more frequently, what threats users fear the most, how often backups are made today and on what mediums, and, most importantly, why data losses will only increase.
Kube-scheduler is an integral component of Kubernetes responsible for scheduling pods to nodes according to specified policies. Often, during the operation of a Kubernetes cluster, we don’t have to think about the exact policies governing pod scheduling, as the default set of kube-scheduler policies works for most everyday tasks. However, there are situations when fine control over the scheduling process is important.
