O documento descreve o Sistema Integrado de Processamento de Dados (SIPD) desenvolvido para Itaipu Binacional. O SIPD integra vários sistemas de tempo real através da plataforma PI System e inclui ferramentas para análise de dados, simulação, análise de árvores de falhas e aplicativos web/desktop.
O filósofo Abu al-Ala al Maari criticou as religiões existentes, afirmando que tanto os muçulmanos, cristãos e judeus estavam errados e que apenas existiam dois tipos de homens: aqueles religiosos sem inteligência e aqueles inteligentes sem religião.
O documento fornece 7 passos para instalar o Ubuntu (Linux) e o Windows XP, começando pela seleção do idioma, escolha da partição para instalar o Ubuntu, seleção da localização e teclado, e finalizando com a escolha do sistema operativo para iniciar após a instalação.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow, releases endorphins, and promotes changes in the brain which help enhance one's emotional well-being and mental clarity.
El maltrato infantil se refiere a acciones u omisiones que causan daño a un niño o niña. Existen tres formas principales: maltrato físico, emocional o psicológico, y abandono o negligencia. El maltrato físico incluye agresiones que pueden causar lesiones, mientras que el maltrato emocional se refiere al hostigamiento verbal. El abandono y negligencia implica la falta de cuidado y protección básicos por parte de los responsables.
The document discusses concurrency and synchronization in distributed computing. It provides an overview of Petr Kuznetsov's research at Telecom ParisTech, which includes algorithms and models for distributed systems. Some key points discussed are:
- Concurrency is important due to multi-core processors and distributed systems being everywhere. However, synchronization between concurrent processes introduces challenges.
- Common synchronization problems include mutual exclusion, readers-writers problems, and producer-consumer problems. Tools for synchronization include semaphores, transactional memory, and non-blocking algorithms.
- Characterizing distributed computing models and determining what problems can be solved in a given model is an important area of research, with implications for distributed system design.

The document discusses weakly supervised learning from video and images using convolutional neural networks. It describes using scripts as weak supervision for learning actions from movies without explicit labeling. Methods are presented for jointly learning actors and actions from scripts, and for action learning with ordering constraints. The use of CNNs for object and action recognition in images is also summarized, including work on training CNNs using only image-level labels without bounding boxes.
This document discusses common C++ bugs and tools to find them. It describes various types of memory access bugs like buffer overflows on the stack, heap, and globals that can lead to crashes or security vulnerabilities. Threading bugs like data races, deadlocks, and race conditions on object destruction are also covered. Other undefined behaviors like initialization order issues, lack of sequence points, and integer overflows are explained. The document provides examples of each type of bug and emphasizes that undefined behavior does not guarantee a predictable result. It concludes with a quiz to find bugs in a code sample and links to additional reading materials.
AddressSanitizer, ThreadSanitizer, and MemorySanitizer are compiler-based tools that detect bugs like buffer overflows, data races, and uninitialized memory reads in C/C++ programs. AddressSanitizer instruments loads and stores to detect out-of-bounds memory accesses. ThreadSanitizer intercepts synchronization calls to detect data races between threads. MemorySanitizer tracks initialized and uninitialized memory using shadow memory to find uses of uninitialized values. The tools have found thousands of bugs with low overhead. Future work includes supporting more platforms and languages and detecting additional bug classes.

This document provides examples and snippets of code for MapReduce, Pig, Hive, Spark, Shark, and Disco frameworks. It also includes two sections of references for related papers and Disco documentation. The examples demonstrate basic MapReduce jobs with drivers, mappers, and reducers in Java, Pig and Hive queries, Spark and Shark table operations, and a Disco MapReduce job.
