Hive on Spark を活用した高速データ分析 - Hadoop / Spark Conference Japan 2016Nagato Kasaki
現在、DMM.comでは、1日あたり1億レコード以上の行動ログを中心に、各サービスのコンテンツ情報や、地域情報のようなオープンデータを収集し、データドリブンマーケティングやマーケティングオートメーションに活用しています。しかし、データの規模が増大し、その用途が多様化するにともなって、データ処理のレイテンシが課題となってきました。本発表では、既存のデータ処理に用いられていたHiveの処理をHive on Sparkに置き換えることで、1日あたりのバッチ処理の時間を3分の1まで削減することができた事例を紹介し、Hive on Sparkの導入方法やメリットを具体的に解説します。

This document discusses PHP file includes and requires and how the PHP opcode cache handles them. It covers how PHP resolves include paths, checks if a file has already been included, and validates file timestamps when revalidating paths. It also discusses using the opcode cache status to view cache metrics and how to invalidate files from the cache.

O documento discute diferentes tipos de dores de cabeça, incluindo a diferença entre cefaléia e dor de cabeça, os mais de 300 tipos de cefaléia, e como a enxaqueca se diferencia de outras dores de cabeça. Também aborda o tratamento da enxaqueca, incluindo opções preventivas e para crises, e esclarece mitos como a relação entre enxaqueca e problemas no fígado.
O documento discute diferentes tipos de cefaléia, incluindo cefaléias primárias e secundárias. A cefaléia mais comumente tratada é a migrânea, que afeta cerca de 12% da população. A migrânea pode ser classificada como com ou sem aura. O tratamento inclui opções farmacológicas para crises agudas e prevenção, além de abordagens não farmacológicas.
Green buildings are designed to reduce environmental impact through efficient use of resources, protecting occupant health, and reducing waste and pollution. They achieve this through features like efficient energy and water usage, non-toxic materials, and effective ventilation. Green buildings provide advantages like lower operating costs due to energy savings, better indoor air quality and worker productivity, and higher property values.
Evaluating performance of centrifugal pump through cfd while modifying the su...eSAT Publishing House
This document discusses evaluating the performance of centrifugal pumps through computational fluid dynamics (CFD) by modifying the suction side geometry. It aims to arrive at the most efficient suction geometry. The document first discusses the importance of proper suction conditions and reviews literature on CFD analyses of pump suction systems. It then outlines the objectives of redesigning the pump suction manifold through CFD to reduce pressure losses and ensure smooth flow. The document concludes by discussing experimental validation of the new design.
The document discusses usability testing, which involves testing a product on representative users to identify usability problems, collect data on user performance, and measure satisfaction, in order to improve the product design through an iterative process before public release. It covers planning tests, conducting tests by having users complete tasks while observers take notes, and analyzing the results to identify issues and make design modifications. The goal of usability testing is to create products that are useful, efficient, engaging, error-tolerant, and easy to learn for the intended users.
The document discusses prototyping and provides guidance on creating paper prototypes. It emphasizes that prototyping is an iterative process used to gain feedback and insights. It recommends starting with storyboarding to plan interactions and convey the setting, sequence, and user experience. Tips are provided for creating paper prototypes quickly using various materials like paper, cardboard, and transparencies. The goal of paper prototyping is to test interaction flows at low cost before implementing a digital prototype.
