Apache Hadoop. Distributed data processing framework Apache Hadoop () is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. It provides a software framework for distributed storage and processing of big data using the MapReduce programming model. Hadoop was originally designed for computer clusters built from commodity hardware, which is still the common use.[3] It has since also found use on clusters of higher-end hardware.[4][5] All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common occurrences and should be automatically handled by the framework.[6] The base Apache Hadoop framework is composed of the following modules: Apache Hadoop's MapReduce and HDFS components were inspired by Google papers on MapReduce and Google File System.[14] History[edit] Architecture[edit] A multi-node Hadoop cluster File systems[edit] Other file systems[edit]
Who is using SitePrism · natritmeyer/site_prism Wiki. Shopa ITV Player Book&Table. Here's Why I Like SitePrism and Why I Might Not Like Cucumber - Polyglot Software. So I’ve been using rspec capybara pretty much exclusively for my acceptance tests for about a year now. The main reason for this is that I, likesomeothers, find its syntax to be good enough for my purposes, and don’t necesarily feel any benefit from a tool like cucumber. Now I understand that there are probably great test suites out there that use cucumber. It’s just that so far, I’ve not managed to encounter a test suite that didn’t become unwieldy and take a long time to understand and/or debug. In general I’ve found that I’ve been lucky enough to work with some very talented and smart developers, who write clean easy-to-understand code that satisfies the business needs incredibly well.
App -> features -> spec Cucumber anti-patterns Anyway, some of the anti-patterns I’ve encountered. So the move away from web_steps.rb was a good one, which made a lot of sense to me at the time, and made me think more clearly about what the tests should be describing. Why I don’t like cucumber No more: Confluence (software) Corporate collaboration software program In 2014, Atlassian released Confluence Data Center to add high availability with load balancing across nodes in a clustered setup. Confluence includes set up CSS templates for styles and formatting for all pages, including those imported from Word documents. Built in search allows queries by date, the page's author, and content type such as graphics.
There is no standard way of adding captions to images in the server version, but captions can be added to images in the cloud version. Official website. GitLab. Open-source Git software package GitLab Inc. was established in 2014 to continue the development of the open-source code-sharing platform launched in 2011 by Dmytriy Zaporozhets. The company's co-founder Sytse Sijbrandij initially contributed to the project and decided to build a business around it.[21][22] GitLab offers its platform using a freemium model.[21] Since its founding, GitLab Inc. has promoted remote work[23] and is known as one of the largest all-remote companies in the world.[24] By 2020, the company employed 1300 people in 65 countries.[23][25] The company participated in the YCombinator seed accelerator Winter 2015 program. By 2015, notable customers included Alibaba Group and IBM.[22] In January 2017, a database administrator accidentally deleted the production database in the aftermath of a cyberattack, causing the loss of a substantial amount of issue data and merge request data.[26] The recovery process was live-streamed on YouTube.[27][28]
Laravel vs CodeIgniter: which one is recommended? Laravel Vs Codeigniter. A difficult choice. Hey fellows. I am in a situation I am sure I could use your comments. I have been working with Codeigniter for 3 years. I find is extremely easy to set up and work with. I started learning Laravel 3 months ago. I have made some progress but since it is very OOP the learning process is taking some time. I am still not comfortable. Today I got a web illiterate client who knows absolutely nothing about web ( he doesnt know CI vs Lara). But I have a feeling I will not be very fast. A part of me wants to do it in Codeigniter ( since its easy set up etc ) but the other part of me wants to take advantage of this situation and do it in Laravel.
Thanks. CodeIgniter. CodeIgniter is an open source rapid development web application framework, for use in building dynamic web sites with PHP. Popularity[edit] CodeIgniter is loosely based on the popular Model-View-Controller development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional.[1] Source code and license[edit] CodeIgniter's source code is maintained at GitHub,[6] and as of the preview version 3.0rc3, is certified open source software licensed with the MIT License. Versions of CodeIgniter prior to 3.0 are licensed under a proprietary Apache/BSD-style open source license.[7] The decision to switch licensing to the Open Software License (OSL) sparked some community controversy,[8] especially about the GPL incompatibility of the new license, to which EllisLab has responded with a series of articles entitled Software License Awareness Week.[9] Version and history[edit] See also[edit] References[edit] External links[edit] Official website.
Symfony. Symfony is a PHP web application framework for MVC applications. Symfony is free software and released under the MIT license. The symfony-project.com website launched on October 18, 2005.[2] Symfony should not be confused with Symphony CMS. Goal[edit] Symfony aims to speed up the creation and maintenance of web applications and to replace repetitive coding tasks. Symfony has a low performance overhead used with a bytecode cache. Symfony is aimed at building robust applications in an enterprise context, and aims to give developers full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized.
Technical[edit] Symfony makes heavy use of existing PHP open-source projects as part of the framework, including: Symfony also makes use of its own components, which are freely available on the Symfony Components site for various other projects: The inclusion and implementation of a JavaScript library is left to the user. [edit] Releases[edit] Model–view–controller. Software design pattern Model–view–controller (MVC) is a software design pattern[1] commonly used for developing user interfaces that divides the related program logic into three interconnected elements.
These elements are the internal representations of information (the model), the interface (the view) that presents information to and accepts it from the user, and the controller software linking the two.[2][3] Traditionally used for desktop graphical user interfaces (GUIs), this pattern became popular for designing web applications.[4] Popular programming languages have MVC frameworks that facilitate the implementation of the pattern. History[edit] One of the seminal insights in the early development of graphical user interfaces, MVC became one of the first approaches to describe and implement software constructs in terms of their responsibilities.[5] In their final design, a model represents some part of the program purely and intuitively. Components[edit] Model[edit] View[edit] Laravel. Open source web application framework, written in PHP Laravel is a free, open-source[3] PHP web framework, created by Taylor Otwell and intended for the development of web applications following the model–view–controller (MVC) architectural pattern and based on Symfony.
Some of the features of Laravel are a modular packaging system with a dedicated dependency manager, different ways for accessing relational databases, utilities that aid in application deployment and maintenance, and its orientation toward syntactic sugar.[4][5]:2,5–9[6][7] The source code of Laravel is hosted on GitHub and licensed under the terms of MIT License.[8] History[edit] Laravel 2 was released in September 2011, bringing various improvements from the author and community. Laravel 5 was released in February 2015 as a result of internal changes that ended up in renumbering the then-future Laravel 4.3 release. Laravel 5.1, released in June 2015, was the first release of Laravel to receive long-term support (LTS). Eloquent ORM - Laravel - The PHP Framework For Web Artisans. Introduction The Eloquent ORM included with Laravel provides a beautiful, simple ActiveRecord implementation for working with your database.
Each database table has a corresponding "Model" which is used to interact with that table. Before getting started, be sure to configure a database connection in config/database.php. Basic Usage To get started, create an Eloquent model. Defining An Eloquent Model class User extends Model {} You may also generate Eloquent models using the make:model command: php artisan make:model User Note that we did not tell Eloquent which table to use for our User model.
Class User extends Model { protected $table = 'my_users'; } Note: Eloquent will also assume that each table has a primary key column named id. Once a model is defined, you are ready to start retrieving and creating records in your table. Retrieving All Records $users = User::all(); Retrieving A Record By Primary Key $user = User::find(1); var_dump($user->name); Querying Using Eloquent Models Chunking Results.
