Python to go
The author explains why they switched from primarily using Python to primarily using Go for serious projects. Some key reasons include that Go has better performance, code quality, testing, and concurrency features compared to Python. While Python is still good for hobby projects, Go enforces error handling, has built-in profiling tools, and makes deployment easier due to compiling to a single binary.
Migrate PHP E-Commerce Site to Go
This document summarizes one company's experience migrating their PHP e-commerce site to the Go programming language. It discusses how they initially rewrote their catalog page in AngularJS and Go, but ran into issues with Facebook OpenGraph integration. For their second release, they decided on a hybrid PHP and Go approach, with Go used to power specific backend modules like caching and shopping cart functionality. The author reflects on lessons learned around thoroughly evaluating new technologies before deploying them and making sure any changes have team consensus.

Title: Exploring Web Development with Python: A Comprehensive Guide
Introduction:
Web development has become an integral part of the modern technological landscape, and Python has emerged as a versatile and powerful language for building web applications. In this comprehensive guide, we will delve into the various aspects of web development using Python, exploring frameworks, libraries, and best practices to create dynamic and scalable web applications.
I. Understanding the Basics of Web Development:
1.1 HTML, CSS, and JavaScript:
Before delving into Python-specific frameworks, it's essential to grasp the fundamentals of web development. HTML provides the structure, CSS adds styling, and JavaScript adds interactivity to web pages. These technologies form the backbone of web development regardless of the programming language used.
1.2 Introduction to Python for Web Development:
Python's readability, simplicity, and extensive libraries make it an excellent choice for web development. Familiarizing yourself with basic Python syntax, data structures, and control flow is crucial before diving into web-specific frameworks.
II. Python Web Frameworks:
2.1 Flask:
Flask is a lightweight and easy-to-use web framework that follows the WSGI (Web Server Gateway Interface) standard. It's ideal for small to medium-sized projects and encourages simplicity and flexibility. We'll explore how to set up a basic Flask application, define routes, and render dynamic templates.
2.2 Django:
Django, a high-level web framework, follows the "batteries-included" philosophy, providing a robust set of features out of the box. From database migrations to user authentication, Django simplifies complex tasks and promotes best practices. We'll cover creating a Django project, defining models, and building views and templates.
III. Frontend Development with Python:
3.1 JavaScript Integration:
While Python handles server-side logic, JavaScript is crucial for client-side interactivity. We'll explore methods to integrate JavaScript frameworks like React or Vue.js into Python-based web applications, allowing for a seamless user experience.
3.2 Template Engines:
Python web frameworks often use template engines to dynamically generate HTML. We'll delve into popular template engines like Jinja2, understanding how to create dynamic and reusable templates for rendering data.
IV. Database Integration:
4.1 Relational Databases (SQLAlchemy):
Python frameworks offer seamless integration with relational databases through libraries like SQLAlchemy. We'll cover database modeling, querying, and migrations, ensuring efficient data storage and retrieval.
4.2 NoSQL Databases (MongoDB with Flask):
For projects requiring flexibility in data storage, we'll explore integrating Flask with MongoDB, a popular NoSQL database. This section covers basic CRUD operations and demonstrates the advantages of using a document-oriented database.
V. RESTful APIs and Web Services:
5.1 Building RESTful APIAn Open Source Workbench for Prototyping Multimodal Interactions Based on Off...
In this paper we present an extensible software workbench for supporting the effective and dynamic prototyping of multimodal interactive systems. We hypothesize the construction of such applications to be based on the assembly of several components, namely various and sometimes interchangeable modalities at the input, fusion-fission components, and also several modalities at the output. Successful realization of advanced interactions can benefit from early prototyping and the iterative implementation of design requires the easy integration, combination, replacement, or upgrade of components. We have designed and implemented a thin integration platform able to manage these key elements, and thus provide the research community a tool to bridge the gap of the current support for multimodal applications implementation. The platform is included within a workbench offering visual editors, non-intrusive tools, components and techniques to assemble various modalities provided in different implementation technologies, while keeping a high level of performance of the integrated system.
The Characteristics of a Successful SPA
The document discusses the characteristics of a successful single page application (SPA). It recommends choosing frameworks and libraries that have good documentation, large communities, and support needed functionality. It also emphasizes building robust, stable APIs and keeping performance in mind from the start. The document suggests optimizing JavaScript and backend code, knowing the runtime environment, and using developer tools to minimize resource-intensive reflows and repaints. Overall, it presents SPAs as a good option for mobile apps if frameworks, libraries, APIs, and performance are chosen and developed carefully.

You will have to deconstruct large parts to get to where you want to be, to build it all up again afterwards. Unfortunately, our software is often built the same way. Wouldn’t it be better if our software behaved like a bag of marbles? So you can just add, remove or replace them at will?
Most of us have taken different approaches to building software: a big monolith, a collection of services, a bus architecture, etc. But whatever your large scale architecture is, at the granular level (a single service or host), you will probably still end up with tightly couple code. Adding functionality means making changes to every layer, service or component involved. It gets even harder if you want to enable or disable features for certain deployments: you’ll need to wrap code in feature flags, write custom DB migration scripts, etc. There has to be a better way!
So what if you think of functionality as loose feature assemblies? We can construct our code in such a way that adding a feature is as simple as adding the assembly to your deployment, and removing it is done by just deleting the file. We would open the door for so many scenarios!
In this talk, I will explain how to tackle the following parts of your application to achieve this goal: WebAPI, Entity Framework, Onion Architecture, IoC and database migrations. And most of all, when you would want to do this. Because… ‘it depends’.

Social Connections 2015 CrossWorlds and Domino
This document discusses CrossWorlds, which allows developing generic web applications using the IBM Domino application server. CrossWorlds is a feature for IBM Websphere Liberty Profile that makes Liberty act like a Domino server to applications. It allows accessing Domino data and services via the OpenNTF Domino API from standard web applications. CrossWorlds provides advantages like Domino's security and data storage along with Liberty's speed and tooling. The OpenNTF Domino API also provides more flexible session handling and data access than traditional XPages development.

Introduction to Python Programming Basics
Python is a popular high-level programming language that can be used for a wide range of applications from simple scripts to complex machine learning programs. It has a simple syntax, extensive standard library, and support for code reuse through modules and packages. Some key strengths of Python include its huge collection of standard libraries for tasks like machine learning, web development, scientific computing, and more. It is also an interpreted language, making it easy to learn and use for both simple and complex programming tasks.
Week 5
The document provides an introduction to programming concepts such as variables, data types, basic math operations, and order of operations. It explains how programs use variables to store and manipulate data in memory and demonstrates basic PHP code examples for printing output, performing math calculations, and assigning values to variables. The examples illustrate fundamental programming concepts like declaring variables, assigning values, and performing arithmetic operations in PHP.
