This document provides an introduction to Docker and containerization. It covers:
1. The differences between virtual machines and containers, and the container lifecycle.
2. An overview of the Docker ecosystem tools.
3. Instructions for installing and using the Docker Engine and Docker CLI to build, run, and manage containers.
4. A demonstration of using Docker Hub to build and store container images.
5. An introduction to Docker networking and volumes.
6. A demonstration of using Docker Compose to define and run multi-container applications.

Docker Compose allows users to define and run multi-container Docker applications with a single command (docker up). It uses a YAML file to configure the application's services and Docker to automatically build images and link containers. With Compose, complex applications can be started and stopped with a single command, rather than multiple docker run commands. It also integrates with the Docker API, allowing it to work with tools like Docker Swarm for multi-host clusters.
Consul is a service discovery tool that allows services to register themselves and discover other services via a distributed key-value store. It provides service discovery, health checking, and distributed configuration management. Consul works by having Consul agents that gossip and use the Raft consensus protocol to maintain a consistent key-value store across datacenters. Clients can access services via HTTP endpoints to register services, discover health checks, and access the key-value store.

Docker is a platform that allows users to build, ship, and run applications by using containers. It solves issues like dependency conflicts, portability, and consistency across development and production. Docker uses containers- isolated environments that package code and dependencies together- to deliver software quickly and reliably. Key Docker concepts include images (read-only templates for creating containers), volumes (for persistent data), registries (for sharing images), and compose files (for defining multi-container apps). Docker also provides networking and clustering functionality to connect containers across multiple hosts.
The document discusses the design and functionality of Docker's build tooling, particularly focusing on BuildKit and containerd. It highlights features such as improved build performance, support for multi-tenancy, and experimental features available in version 18.06. The presentation emphasizes the architecture and capabilities of BuildKit for efficient image building, management, and caching, as well as its integration with containerd and compatibility with existing Docker workflows.

This document proposes methods for analyzing manga styles using image and text features. It extracts panel, screentone, character, and line features from manga pages. Latent Dirichlet Allocation is used to build a latent style model that represents manga as mixtures of latent style elements. The features and model are used to distinguish manga styles, retrieve artworks by the same artist or movement, and find artworks from the same period. Evaluation shows the panel, screentone, and line features effectively capture differences between manga styles.

This document summarizes a study that estimated the smoking-attributable expenditures (SAEs) for people aged 35 or older in Taiwan in 2000 from the perspective of health insurers. The total SAE was estimated to be US$467.3 million, representing 8.5% of total medical expenditures for that population. Kidney disease, ischemic heart disease, and accidents accounted for the highest SAE costs. The study is an improvement over previous work as it used relative risk data from large cohort studies and health insurance claims data to estimate disease-specific expenditures. However, it did not account for costs of passive smoking or non-insurance expenditures.
