Queue is a data structure on disk or in memory that stores references to messages and provides their copies to consumers. A Queue represents an Erlang process with state (where messages can be cached). 1,000 queues may take up about 80MB. Binding is a rule that informs the broker to which queue messages should be directed. […]
In this article, we will describe the minimum set of actions required for the optimal installation of Firebird DBMS version 3.0 on new Linux distributions. The examples will focus on CentOS 8 and Ubuntu 19. For the 'delivery' of the Firebird distribution to the target system, this guide has chosen the option of downloading a tar.gz archive from a link on the official project site (firebirdsql.org). For the most impatient — right away […]

Historically, command-line utilities in Unix systems have been better developed than in Windows, but with the advent of a new solution, the situation has changed. For PowerShell, scripts can be written in an interpreted multi-paradigm language that incorporates elements of classical procedural, object-oriented, and even functional programming: conditional transitions, loops, variables, arrays, hash tables, classes, error handling, as well as functions, cmdlets, and pipelines. The previous article […]
Historically, command-line utilities in Unix systems have been better developed than in Windows, but with the advent of a new solution, the situation has changed. Windows PowerShell allows system administrators to automate most routine tasks. With it, one can change settings, stop and start services, and perform maintenance on most installed applications. Considering the blue window as just another command interpreter would be incorrect. […]
