Percona XtraDB Cluster is an implementation of Galera Replication developed by Percona LLC. It allows for multi-master, synchronous replication across MySQL nodes. Updates are replicated in parallel at the row-level for consistency. Automated state snapshot transfers help join or recover nodes without downtime or data loss. While performance is reduced compared to single-server, it provides high availability and data consistency in a flat, master-less topology.
This document discusses technology startups in Turkey across three categories: e-commerce, games, and content. E-commerce startups like Hepsiburada, Markafoni, and Gittigidiyor have helped make Turkey the second fastest growing e-commerce market after India. Game startups such as Peak Games and Monochroma develop and sell games, with the Turkish video game market growing substantially. Content startups including Ekşisözlük, Böbiler, and Onedio create unique content and have millions of monthly visitors. Overall, technology startups have become a significant part of Turkey's growing digital economy.
Revolution R Enterprise - 100% R and More Webinar PresentationRevolution Analytics
R users already know why the R language is the lingua franca of statisticians today: because it's the most powerful statistical language in the world. Revolution Analytics builds on the power of open source R, and adds performance, productivity and integration features to create Revolution R Enterprise. In this presentation, author and blogger David Smith will introduce the additional capabilities of Revolution R Enterprise.
El artículo habla sobre la importancia de educar en valores a través del fútbol base. Explica que los entrenadores deben ser modelos a seguir para los niños, enseñándoles el deporte de una manera divertida y enfocada en el compañerismo y el respeto. También destaca la importancia de que los padres y el entorno futbolístico apoyen a los niños de una manera positiva y comprometida con su desarrollo personal a través del deporte.
Este documento describe los componentes básicos de los sistemas de control, incluyendo los objetivos de control, componentes del sistema de control y resultados. Explica que los sistemas de control en lazo abierto son más simples que los sistemas de control en lazo cerrado, los cuales usan realimentación para mejorar la precisión. También proporciona ejemplos de sistemas de control de velocidad en ralentí de un automóvil, control de una rueda de impresión y control de temperatura en la cabina de un coche.
Para desarrollar un plan de clase efectivo se deben considerar los siguientes elementos: establecer objetivos claros y alcanzables, seleccionar actividades y recursos didácticos adecuados, y evaluar periódicamente el progreso de los estudiantes para ajustar el plan según sea necesario.

This document discusses the Crystal programming language and compares it to Ruby. Crystal is a compiled, statically typed language that is inspired by Ruby. It aims to provide Ruby-like syntax and semantics but with better performance due to being compiled ahead of time. The document provides examples of Crystal code and demonstrates how Crystal is faster than Ruby for the Fibonacci number problem due to being compiled. It also highlights some key differences between Crystal and Ruby like static typing, overloading, and macros.
The document is a presentation in Japanese about character sets and collations in MySQL. It discusses how MySQL treats emoji characters like sushi and beer the same by default, but PostgreSQL does not. It explains that MySQL has both a character set (which defines how characters are encoded as bytes) and collation (which defines the sorting rules). For the UTF-8 character set, it shows the different collation options and how they treat letters, emojis, hiragana/katakana, and case sensitivity differently. It expresses a need for a Japanese-specific collation that properly distinguishes Japanese characters.
