[Recommended Reading] Artificial Intelligence

Source: Artificial Intelligence Wikipedia

“Artificial intelligence (AI, also machine intelligenceMI) is intelligence exhibited by machines, rather than humans or other animals (natural intelligence, NI). In computer science, the field of AI research defines itself as the study of “intelligent agents”: any device that perceives its environment and takes actions that maximize its chance of success at some goal.[1] Colloquially, the term “artificial intelligence” is applied when a machine mimics “cognitive” functions that humans associate with other human minds, such as “learning” and “problem solving”.[2]Read more…

[Recommended Reading] Quantum computing

Source: Quantum Computing Wikipedia

“Quantum computing studies theoretical computation systems (quantum computers) that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data.[1] Quantum computers are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states. A quantum Turing machine is a theoretical model of such a computer, and is also known as the universal quantum computer. The field of quantum computing was initiated by the work of Paul Benioff[2] and Yuri Manin in 1980,[3] Richard Feynman in 1982,[4] and David Deutsch in 1985.[5] A quantum computer with spins as quantum bits was also formulated for use as a quantum spacetime in 1968.

Reliability Analysis of a Web Server by FTA Method

Authors: Gabriel PETRICA, Ionut – Daniel BARBU, Sabina – Daniela AXINTE, Cristian PASCARIU

Published: ADVANCED TOPICS IN ELECTRICAL ENGINEERING – ATEE 2017

“FTA (Fault Tree Analysis) is one of the most used methods for reliability analysis and to quantify the risks associated with the failures of systems. This method performs analysis of the combination of events that can lead to a critical system failure (called Top Event of the designed Fault Tree) and allows calculating the probability of failure. In this paper, has been built the Fault Tree for a Web server considering failures that may occur at hardware level (the basic components for the considered computer system). After realizing the Fault Tree, were made two types of analysis: qualitative (which led to the identification of minimal cut sets) and quantitative (this allowed the calculation of the probability of occurrence of the considered critical event – <<Web server not operational>>.” Read more…

“In computing, Red Hat Satellite is a systems-management product by the company Red Hat which allows system administrators to deploy and manage Red Hat Enterprise Linux (RHEL) hosts. A Satellite server registers with Red Hat Subscription Management, mirrors all relevant software like security errata and bug fixes, and provides this together with locally added software and configuration to the attached servers. The managed hosts register against the local Satellite server and access the provided resources like software packages, patches, configuration, etc. while they also provide information about the current health state of the server to the Satellite.
