files. Input and output devices, and generally all
devices, are considered to be files, according to the
system.

Hadoop is an open-source software framework for distributed storage and processing of large datasets across clusters of computers. The core of Hadoop includes HDFS for distributed storage, and MapReduce for distributed processing. Other Hadoop projects include Pig for data flows, ZooKeeper for coordination, and YARN for job scheduling. Key Hadoop daemons include the NameNode, Secondary NameNode, DataNodes, JobTracker and TaskTrackers.

Influxdb

This document provides instructions for installing and configuring InfluxDB, CollectD, and Grafana on CentOS 7 to monitor server metrics. It involves: 1. Installing CollectD to collect metrics and configure it to send data to InfluxDB. 2. Downloading and installing InfluxDB using yum, then modifying the configuration to enable the CollectD plugin and set database details. 3. Installing and starting Grafana for visualization of metrics stored in InfluxDB.

Unqlite

Paul Myeongchan Kim

UnQLite is an embeddable, serverless, zero-configuration NoSQL database that uses a single database file with no external dependencies. It provides ACID transactions with key-value and document storage and supports efficient O(1) lookups. The database can be accessed from C code using a simple API to open and close the database, store, retrieve, append, and delete key-value pairs, and iterate over records with a cursor. It also supports loading and storing files and scripting functionality through Jx9 scripts.

Nutch is an open source web crawler built on Hadoop that can be used to crawl websites at scale. It integrates directly with Solr to index crawled content. HDFS provides a scalable storage layer that Nutch and Solr can write to and read from directly. This allows building indexes for Solr using Hadoop's MapReduce framework. Morphlines allow defining ETL pipelines to extract, transform, and load content from various sources into Solr running on HDFS.

Data warehouse on Kubernetes - gentle intro to Clickhouse Operator, by Robert...

Altinity Ltd

San Diego Cloud Native Computing Meetup, January 23, 2020 Presented by Robert Hodges, Altinity CEO Data services are the latest wave of applications to catch the Kubernetes bug, but how many people would guess that includes data warehouses? We proved it works by developing the ClickHouse Kubernetes operator, which is now in production use at companies like Mux.com. It's an open source operator to stand up and run ClickHouse, a popular Apache 2.0 data warehouse that can return queries on trillions of rows in seconds or less. This talk introduces ClickHouse and shows why it's a 'cloud friendly' DBMS. We'll go mano-a-mano with the ClickHouse operator, showing how you can spin up data warehouses in 60 seconds or less. We'll cover issues like storage management, monitoring and upgrade. In short, everything you need to know to try running your own ClickHouse data warehouses on Kubernetes.

It explains that logical replication in PostgreSQL replicates only DML statements, while physical replication replicates the entire database. It describes using pg2ch to replicate changes from PostgreSQL to ClickHouse tables using CollapsingMergeTree, ReplacingMergeTree, or MergeTree engines. Pg2ch accumulates changes in buffers and handles updating/deleting rows when using CollapsingMergeTree or ReplacingMergeTree engines.

Harsh Shrimal

Linux is a fully-networked, multi-user, multitasking operating system similar to Unix. It was created in 1991 by Linus Torvalds and is now used widely due to its low cost, stability, and ability to run on different hardware platforms. Linux uses a command line interface where users log in and issue commands to perform tasks like copying files, installing software, and checking system resources. Common commands include ls to list files, cd to change directories, and man to view manuals.

Linux is a fully-featured open source operating system based on Unix. It was created by Linus Torvalds in 1991 and has since grown in popularity. Linux uses a kernel to manage hardware resources and runs on multiple hardware platforms. Users interact with Linux through a shell and can execute commands, manage files and directories, and perform other tasks. Common Linux commands include ls, cd, pwd, cp, and more.

Understanding computer vision with Deep Learning

CloudxLab

Computer vision is a branch of computer science which deals with recognising objects, people and identifying patterns in visuals. It is basically analogous to the vision of an animal. Topics covered: 1. Overview of Machine Learning 2. Basics of Deep Learning 3. What is computer vision and its use-cases? 4. Various algorithms used in Computer Vision (mostly CNN) 5. Live hands-on demo of either Auto Cameraman or Face recognition system 6. What next?

Deep Learning Overview

CloudxLab

Recurrent Neural Networks

CloudxLab

This document discusses recurrent neural networks (RNNs) and their applications. It begins by explaining that RNNs can process input sequences of arbitrary lengths, unlike other neural networks. It then provides examples of RNN applications, such as predicting time series data, autonomous driving, natural language processing, and music generation. The document goes on to describe the fundamental concepts of RNNs, including recurrent neurons, memory cells, and different types of RNN architectures for processing input/output sequences. It concludes by demonstrating how to implement basic RNNs using TensorFlow's static_rnn function.

Natural Language Processing

CloudxLab

Natural Language Processing (NLP) is a field of artificial intelligence that deals with interactions between computers and human languages. NLP aims to program computers to process and analyze large amounts of natural language data. Some common NLP tasks include speech recognition, text classification, machine translation, question answering, and more. Popular NLP tools include Stanford CoreNLP, NLTK, OpenNLP, and TextBlob. Vectorization is commonly used to represent text in a way that can be used for machine learning algorithms like calculating text similarity. Tf-idf is a common technique used to weigh words based on their frequency and importance.

Naive Bayes

CloudxLab

- Naive Bayes is a classification technique based on Bayes' theorem that uses "naive" independence assumptions. It is easy to build and can perform well even with large datasets. - It works by calculating the posterior probability for each class given predictor values using the Bayes theorem and independence assumptions between predictors. The class with the highest posterior probability is predicted. - It is commonly used for text classification, spam filtering, and sentiment analysis due to its fast performance and high success rates compared to other algorithms.

Autoencoders

CloudxLab

An autoencoder is an artificial neural network that is trained to copy its input to its output. It consists of an encoder that compresses the input into a lower-dimensional latent-space encoding, and a decoder that reconstructs the output from this encoding. Autoencoders are useful for dimensionality reduction, feature learning, and generative modeling. When constrained by limiting the latent space or adding noise, autoencoders are forced to learn efficient representations of the input data. For example, a linear autoencoder trained with mean squared error performs principal component analysis.

Training Deep Neural Nets

CloudxLab

The document discusses challenges in training deep neural networks and solutions to those challenges. Training deep neural networks with many layers and parameters can be slow and prone to overfitting. A key challenge is the vanishing gradient problem, where the gradients shrink exponentially small as they propagate through many layers, making earlier layers very slow to train. Solutions include using initialization techniques like He initialization and activation functions like ReLU and leaky ReLU that do not saturate, preventing gradients from vanishing. Later improvements include the ELU activation function.
