Representational State Transfer Un article de Wikipédia, l'encyclopédie libre. REST (representational state transfer) est un style d'architecture pour les systèmes hypermédia distribués, créé par Roy Fielding en 2000 dans le chapitre 5 de sa thèse de doctorat. Il trouve notamment des applications dans le World Wide Web. Contraintes[modifier | modifier le code] Une architecture REST doit respecter les contraintes suivantes : Client-serveur : les responsabilités sont séparées entre le client et le serveur. Description[modifier | modifier le code] Assimilation à un protocole ou un format[modifier | modifier le code] Ce style architectural s'applique tout autant à la réalisation d'applications pour un utilisateur humain qu'à la réalisation d'architectures orientées services destinées à la communication entre machines. RPC ainsi que SOAP ne sont pas des styles d'architecture mais des protocoles. Avantages de REST[modifier | modifier le code] Inconvénients de REST[modifier | modifier le code] ↑ (fr) Thèse de Roy T.

Graphviz System for Network Visualization Get the Big Picture: Visualizing Complex Data Graphviz is network visualization software for creating high-quality, readable node-link diagrams of large-scale data sets (1,000,000 and more nodes), and to do so completely automatically, without manual editing or cleanup. Any system or interface that deals with relationships between objects can benefit from Graphviz visualizations, including networking, databases and data analysis, bioinformatics, software engineering, programming languages and tools, and machine learning. Datasets of 1,000,000 nodes and higher present many hard problems, and Graphviz was one of the first programs developed specifically to handle the problems of large graphs, pioneering new methods and algorithms in three key areas: Readability. Scale. Display and exploration. Graphviz has long been available as open source and is often used as a graphing service for other programs.
How To Use SFTP to Securely Transfer Files with a Remote Server Introduction FTP, or “File Transfer Protocol” is a popular method of transferring files between two remote systems. SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way over a secure connection. The advantage is the ability to leverage a secure connection to transfer files and traverse the filesystem on both the local and remote system. In almost all cases, SFTP is preferable to FTP because of its underlying security features and ability to piggy-back on an SSH connection. FTP is an insecure protocol that should only be used in limited cases or on networks you trust. Although SFTP is integrated into many graphical tools, this guide will demonstrate how to use it through its interactive command line interface. How to Connect with SFTP By default, SFTP uses the SSH protocol to authenticate and establish a secure connection. ssh sammy@your_server_ip_or_remote_hostname exit Getting Help in SFTP help
cunning ramblings in codecraft – Pseudo-random Contributions to the Global Mind-meld How To Install Nginx on Ubuntu 14.04 LTS Introduction Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or a reverse proxy. In this guide, we'll discuss how to get Nginx installed on your Ubuntu 14.04 server. Prerequisites Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin. Step One — Install Nginx We can install Nginx easily because the Ubuntu team provides an Nginx package in its default repositories. Since this is our first interaction with the apt packaging system in this session, we should update our local package index before we begin so that we are using the most up-to-date information. sudo apt-get update sudo apt-get install nginx You will probably be prompted for your user's password.

7 awesome browser features New APIs for the web seem to be released every week. It would be cool to be able to use them, but if you need to make sites for the average user, you won’t be able to implement them for years – right? Wrong. Exploring the latest and greatest of the web platform means you get to use the best tools at your disposal for your users and help push the web forward. Here is a number of different features – some old, some new, all underused – that can be implemented quickly on your site, and will be almost guaranteed to improve the experience. 01. If you have ever browsed the internet over hotel Wi-Fi, 2G, or any other ungodly slow connection over the past few years, you will have undoubtedly encountered FOUT (flash of unstyled text). The reason is that historically, browsers hide text from the user until the custom font has been loaded. Monitoring font rendering on the web has always been tricky, because we’ve never had a way to know whether or not a font has been loaded. 02. <! And that’s it!
