The reasons for using Apache HTTPD will be discussed later in the post. Thus, the solution must meet the following requirements for organizing an RPM repository: Free Immediate availability of the package in the repository a few seconds after uploading to the storage […]
Sooner or later, many encounter the need to make bulk edits to table records. I've already discussed how to do this effectively and how to avoid pitfalls. Today, I will touch upon the second aspect of bulk updates — the triggers that come into play.

This article presents a method of fuzzy induction developed by the author, integrating concepts from fuzzy mathematics and fractal theory. It introduces the notion of the recursion degree of a fuzzy set and provides a description of the incomplete recursion of a set as its fractional dimension for modeling a subject area. As an application domain for the proposed method and the knowledge models created based on it as fuzzy sets, we consider life cycle management […]

On February 27, 2020, the free certification authority Let’s Encrypt issued its billionth certificate.
