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. In turn, we decided to assist them by writing detailed instructions for setting up remote access based on the FortiGate solution: Remote access via IPsec VPN Remote access via SSL VPN Additionally, we have gathered a wealth of other material that may also be […]

The company also promised to present a new version of the technology with improved features in the second quarter of this year. StoreMI technology was introduced alongside the Ryzen 2000 series processors (Pinnacle Ridge) and the corresponding chipsets […]
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%) […]
The release of the Apache HTTP Server 2.4.43 has been published (version 2.4.42 was skipped), featuring 34 changes and addressing 3 vulnerabilities: CVE-2020-1927: a vulnerability in mod_rewrite that allows the server to be used for redirecting requests to other resources (open redirect). Some mod_rewrite settings may lead to redirecting users to another link encoded with a newline character inside the parameter used in existing […]
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.
Mozilla developers have released new versions of the Firefox 74.0.1 and Firefox ESR 68.6.1 web browsers. Users are advised to update their browsers as the new versions fix two zero-day vulnerabilities that are being actively exploited by hackers. These vulnerabilities, CVE-2020-6819 and CVE-2020-6820, relate to how Firefox manages its memory space. They are known as use-after-free vulnerabilities […]
The topic of harvesting electricity from "the air"—from electromagnetic noise, vibrations, light, humidity, and much more—interests both civilian researchers and their counterparts in uniforms. Researchers from Pennsylvania State University have contributed to this subject. They managed to extract electricity with a power output of several milliwatts from the magnetic fields of nearby electrical wiring, which is enough, for instance, […]
