This document discusses converting Django apps into reusable services. It begins by explaining the typical structure of a Django project with multiple apps. It then discusses some of the challenges with this monolithic structure in terms of reusability, scalability and maintainability.
The document proposes converting apps into reusable services with defined contracts for communication. It provides examples of defining API endpoints and authentication. Converting apps to services allows for improved reusability as apps can be developed and updated independently. It also enables better scalability by removing dependencies between apps.
Introducing Assetic: Asset Management for PHP 5.3Kris Wallsmith
The performance of your application depends heavily on the number and size of assets on each page. Even your blazingly fastest Symfony2 application can be bogged down by bloated Javascript and CSS files. This session will give you a basic introduction to PHP's new asset management framework, Assetic, and explore how it integrates with Symfony2 for a pleasant, common sense developer experience.

A year ago, I was a committed VPS and dedicated-machine deployer. I thought the cloud imposed silly restrictions - how dare you take away my shell account! Whaddya mean I can't save files locally? Since then, I've had some interesting experiences. I've worked on big cloud-deployed systems, and certain large traditionally-deployed systems, and I've seen how a lot of the decisions that you're ... encouraged to make when designing an app to run in the cloud. Most interestingly, I've discovered how those same decisions can make for a much better app regardless of where it'll end up. In this talk, I'll share those architectural patterns with you, and show why they work. Hopefully, I'll convince all of you to build cloud castles -- even if you've got your foundation firmly on the ground.
Starting from Constructor Function and Object.create() as methods for creating objects in Javascript, we analize a couple of way to bootstrap a jQuery Plugin.
Presentation for azPHP on setting up a new project using Zend_Tool. Also goes over creating basic modules, controllers, actions, models and layouts.

And now you have two problems. Ruby regular expressions for fun and profit by...Codemotion
A wise hacker said: Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems.
Regular expressions are a powerful tool in our hands and a first class citizen in ruby so it is tempting to overuse them. But knowing them and using them properly is a fundamental asset of every developer.
We’ll see hands-on examples of proper Reg Exps usage in ruby code, we’ll also look at bad and ugly cases and learn how to approach writing, testing and debugging regular expressions.
Drupal 8 leverages Assetic for managing Javascript and CSS assets. This library abstracts the headaches of integrating with the burgeoning universe of asset pre-processors and optimization tools available to the modern developer.
The lead developer of Assetic will give a tour of the library and discuss the current state of the project, its strengths, and its weaknesses, and also touch on the future: Assetic 2.0.
Multi-Tenancy is a critical component of any Software as a Service (SaaS) application, which enables one application instance to serve multiple organizations, or tenants. This presentation by Scott Crespo covers the basics of multi-tenant architectures, and how to implement multi-tenancy using Python, Django, and the open-source project known as Django Tenant Schemas.

S.O.L.I.D. - Павел Кохан, Python Meetup 26.09.2014Python Meetup
Ежедневно разработчикам приходится писать десятки классов для разного рода функционала. Этот функционал может быть связан между собой или иметь разные функции. Нередко, сопровождая чужой код, программист, который более или менее понимает как должен реализовываться класс, видит картину, где, к примеру, класс «Товар» изменяет баланс клиента. По сути это в корне неверно!
Доклад будет рассматривать такую проблему как правильного написания классов. Данные 5 принципов можно применять к любому объектно-ориентированному языку, но в рамках Python meetup примеры будут продемонстрированы на python.
Данный доклад рассматривает 5 основных принципов, где каждая буква в аббревиатуре обозначает свой принцип.
S – Single responsibility principle (Принцип единой обязанности):
O – Open/Closed principle (Принцип Открытости/Закрытости)
L – Liskov substitution principle (Принцип постановки Барбары Лисков)
I – Interface segregation principle (Принцип разделения интерфейса)
D – Dependency inversion principle (Принцип инверсий зависимостей)
Como DDD e Strategic Design estão nos ajudando a modernizar um LegadoLuiz Costa

Gli anni 90 furono dirompenti per i tradizionali modelli di business con la corsa per una presenza sul web, oggi, le interfacce di programmazione (API) rappresentano il nuovo must-have per le aziende nei confronti dei clienti e delle community. Cosa è cambiato? Social Network, Social Commerce, Social Content e gli apostoli Facebook, Twitter, Amazon e eBay, ci guidano alla cultura generazionale del “semplice”: Applicazioni utente intelligenti e mirate veicolate da Apple, Android ed i diversi Store.
I dispositivi mobili sono la nostra nuova appendice e le applicazioni sono la moneta di scambio

Does Behaviour Driven Development have a role in the infrastructure world? Enter Behaviour Driven Infrastructure where systems administrators can apply some simple open source tools and BDD principles to make infrastructure management more powerful, more insightful and deliver more value to their customers.
The typical enterprise monitoring and configuration management set-up for a website is:
- Is the Apache package installed and the appropriate version?
- Is the Apache service running?
- Can I connect to the HTTP port and is HTML returned?
- Multiply this by a few hundred iterations of hosts and types of services and you’re probably looking at your typical Nagios, Puppet, Cfengine, Hyperic set-up.
All this monitoring misses something critical though – we’re not actually monitoring that the service does what it should. Yes, it matters whether Apache is installed, the Apache service is running, and you can connect to HTTP but does this actually prove anything about the availability of the service we’re managing and providing for our customers? Nope…
We need to demonstrate more than just a check that says the Apache server is up. We need to demonstrate that the service delivered by that infrastructure was available to our customers AND functioning as intended.
Enter Behaviour Driven Infrastructure or BDI which applies the principles of Behavioural Driven Development to the management of infrastructure. In this presentation you’ll learn:
- How Behaviour Driven Development works
- What makes a behavioural test
- How to install and use Cucumber to perform BDI
- Practical examples of behavioural tests in Cucumber, and
- How to integrate BDI into your work flow and your enterprise monitoring and configuration management frameworks.
Describes Outside-In development and Behvaiour Driven Development. Illustrates basic Cucumber usage within a Rails app and then goes over more advanced topics such as JS as web services.

Are you interested in learning about Web/App Development and Design and SAAS Services?💰💻📱 Then this article is perfect for you! In this article, we will discuss everything you need to know about how to use web/app development and design and SAAS services to make money.
💥 Introduction:
Web/App Development and Design and SAAS Services have been around for quite some time now. It has revolutionized the way businesses operate, communicate and connect with their customers. SAAS (Software as a Service) is a cloud-based software delivery model that has become increasingly popular among businesses. It allows businesses to access and use software applications through the internet, rather than installing and maintaining them on their own servers. This has led to a significant reduction in costs and improved efficiency.
Web/app development and design and SAAS services are the future of entrepreneurship for several reasons. First, they allow for the creation of unique and innovative solutions that can solve real-world problems. With web/app development and design, entrepreneurs can create digital products and services that can be accessed by anyone with an internet connection. SAAS services, on the other hand, allow for the delivery of software solutions without the need for local installation or maintenance. This makes it easier for entrepreneurs to offer their products and services to customers without the need for significant overhead costs.
Another reason why web/app development and design and SAAS services are the future of entrepreneurship is their scalability. Digital products and services can be easily replicated and distributed to a large number of customers, allowing entrepreneurs to quickly grow their businesses without the need for significant investment. Additionally, SAAS services can be easily updated and improved, providing customers with the latest features and functionality.
Finally, web/app development and design and SAAS services are the future of entrepreneurship because they enable entrepreneurs to work remotely. With the rise of digital technology, entrepreneurs can now work from anywhere in the world, collaborate with teams across different time zones, and provide services to customers all over the globe. This provides entrepreneurs with more flexibility, freedom, and opportunities to grow their businesses.
Overall, web/app development and design and SAAS services are the future of entrepreneurship because they enable entrepreneurs to create innovative solutions, scale their businesses quickly, and work remotely from anywhere in the world.
