Learn ruby intro
This document provides an introduction to Ruby programming concepts including numbers, strings, variables, and objects. Key points covered include:
- How to use the interactive Ruby shell IRB and Ruby IDE Netbeans
- Common number methods like addition, subtraction, and converting between integers and floats
- String interpolation, converting between strings and integers, and common string methods
- Here documents for multi-line strings and converting between strings and arrays

Prolog programming
This document discusses Prolog programming. It covers data structures in Prolog like lists and terms, programming techniques like guess-and-verify queries and open lists, and control in Prolog through goal ordering and rule selection. Lists can represent data structures and terms through partial specification with variables. Programming with open lists and difference lists allows modification of data.
Game theory
1) Game theory analyzes strategic decision-making between players in situations called games. Games can be modeled using normal or extensive form.
2) In normal form, all choices are made simultaneously. Players choose strategies and receive payoffs. Dominant strategies and dominance can be identified.
3) Extensive form models sequential choices using game trees. Backward induction analyzes the game moving backwards in time from end to start. Imperfect information means some information is unknown.
How analysis services caching works
This document discusses how Analysis Services caching works and provides strategies for warming the Storage Engine cache and Formula Engine cache. It explains that the Storage Engine handles data retrieval from disk while the Formula Engine determines which data is needed for queries. Caching can improve performance but requires consideration of memory usage, cache structures, and data granularity. The document recommends using the CREATE CACHE statement and running regular queries to pre-populate the caches, while being mindful of how security and non-deterministic elements can impact cache sharing and scoping. Automating cache warming through SQL Server Agent jobs or SSIS packages is suggested.
Key exchange in crypto
The document discusses key distribution and authentication using symmetric and asymmetric cryptography. It describes the Kerberos protocol which uses a key distribution center (KDC) to authenticate users and distribute session keys. It also discusses using public key certificates and digital signatures to solve the key distribution problem by having a certificate authority (CA) sign public keys.
Principales debates de los foros
El documento habla sobre el uso de recursos tecnológicos en la educación, incluyendo herramientas digitales, realidad virtual, impresión 3D y aprendizaje colaborativo. También discute el papel de los maestros como guías tecnológicos y la importancia de capacitarse continuamente en nuevas tecnologías para la educación.

Text classification-php-v4
This document summarizes text classification in PHP. It discusses what text classification is, common natural language processing terminology like tokenization and stemming, Bayes' theorem and how it relates to naive Bayes classification. It provides examples of tokenizing, stemming, stopping words, and building a naive Bayes classifier in PHP using the NlpTools library. Key steps like training and testing a classifier on sample text data are demonstrated.

The document outlines a marketing campaign for Biti's, a Vietnamese footwear brand, to introduce a new product called Biti's II flip-flops. It aims to double flip-flop sales within one year and transform Biti's image from a outdated brand to a contemporary one for young adults aged 22-30. Biti's II offers a strap that allows it to be worn as either a sandal or flip-flop, appealing its dual nature. The campaign strategy focuses on digital and social media, producing videos and content to build awareness of Biti's II and its message that "contrasts come in pair" among young urban consumers. Key performance indicators include sales growth and digital mentions.
Galileo Galilei -Spanish
Galileo Galilei fue un físico, matemático, astrónomo y filósofo italiano nacido en 1564 que realizó importantes descubrimientos e inventos científicos a través de la experimentación. Demostró que la Tierra giraba alrededor del Sol, lo que iba en contra de las creencias aceptadas de la época y llevó a que la Iglesia lo condenara por herejía.
Linked list
The document discusses lists and linked lists. It begins by describing lists and their implementations using arrays and linked lists. It then focuses on linked list implementations, describing linear linked lists and their representation, operations like traversal, search, insert, and delete. Doubly linked lists are also covered, along with their representation and similar operations. The document provides detailed code examples for many of the linked list operations.
Python basics
A program is a sequence of instructions that are run by the processor. To run a program, it must be compiled into binary code and given to the operating system. The OS then gives the code to the processor to execute. Functions allow code to be reused by defining operations and returning values. Strings are sequences of characters that can be manipulated using indexes and methods. Common string methods include upper() and concatenation using +.
Object model
The document discusses the key elements of the object model, including abstraction, encapsulation, modularity, and hierarchy. It explains that abstraction is one of the fundamental ways to cope with complexity in software design. Abstraction focuses on the essential characteristics of an object that distinguish it from other objects, from the perspective of the viewer. The object model provides a conceptual framework for object-oriented programming that is based on these elements.
Datamining with nb
This document provides an overview of Naive Bayes classifiers. It begins by explaining Bayes' theorem and how it can be used for classification problems. It then shows an example dataset and how to estimate probabilities from the data to build a Naive Bayes model. The key assumptions of Naive Bayes are conditional independence between attributes given the class. The document demonstrates how to classify a new data point by calculating the posterior probabilities for each class and selecting the class with the highest probability.
Maven
Maven is a build automation tool used to manage Java projects through their build, reporting, and documentation lifecycles. It is based on conventions like standard directory layout and dependency management that allow reuse of build logic. Maven projects are created using the mvn archetype:create command and common commands include mvn compile, package, install, clean, and site. The Eclipse Maven plugin integrates Maven projects into the Eclipse IDE.
Programming for engineers in python
The document discusses several topics in programming for engineers in Python including:
1) Sample problems, hash functions, dictionaries, and a car simulation will be covered.
2) Functions can be arguments to other functions, as shown through a function that prints "spam" twice when passed as an argument.
3) Fermat's Last Theorem is checked using a function, and it is shown that previous examples up to n=3 check out according to the theorem.
