1 like•269 views

This document discusses considerations for choosing the best programming language for a web product based on different use cases and business needs. It outlines several common cases such as classic CRUD web portals, real-time applications, machine learning, and blockchain and recommends languages like PHP, Ruby, Node.js, Python, Go, and Elixir based on the technical requirements. The key takeaway is that there is no single best language and business goals should dictate the tools based on factors like human resources, ecosystem, and scalability.

It's all about behaviour, also in php - phpspec

Giulio De Donato

The document discusses test-driven development (TDD) and behavior-driven development (BDD). It explains that BDD uses external specifications to describe behavior before coding starts. This solves issues with TDD like where to begin and what to test. BDD uses a double cycle of writing scenarios in Behat and then examples in Phpspec at the internal class level. Phpspec is used to describe behavior through examples before coding classes. The document provides instructions on installing Phpspec and describes how to define a specification and examples.

DSLs: what, why, how

Mikhail Barash

A DSL (domain-specific language) is a computer programming language focused on a particular domain that has a limited but expressive syntax. DSLs can improve development productivity by allowing programmers to express solutions in terms that are meaningful to both programmers and domain experts. DSLs communicate the intent of a system more clearly than a general purpose language. While DSLs have benefits, they also have drawbacks such as the cost to build and maintain them, and the risk that the language scope may expand over time.

What if-your-application-could-speak

Marcos Vinícius

Imagine a team developing to a specific business domain. We use languages to communicate with the client, company and within the team. We also use programming languages to develop the software. And still, we want our code to express, no only a correct syntax for that language, but the knowledge of the business domain in which we are developing. And if it was possible to capture the business meaning and transforme it into a language? This talk is about DSLs, it's architecture, business use, and also how to implement and test them.

Using Rasa to Power an Immersive Multimedia Conversational Experience | Rasa ...

Rasa Technologies

Human-to-human electronic communication has moved from text (email) to voice (VoIP) to augmented video (Zoom/Skype). Similarly, the medium for human-to-machine conversation has moved from text (chatbots) to voice, with voice-enabled chatbots in wide use today. The next step in this evolution is a video-enabled conversational experience. Each medium change brings its own technical challenges. Creating a good voice experience involves more than just hooking up a chatbot to a text-to-speech and speech-to-text service. Vocinity has developed a platform for voice-enabled chatbots that has been in production for almost 2 years. We're updating our platform to support a multimedia experience where the bot communicates via video, voice and text messages and images. Using Rasa to provide the conversational logic for the immersive multimedia bot enables us to meet the challenges in voice/video communication. Rasa’s power and flexibility enabled us to extend it to support voice and video. Presented by CTO of Vocinity, Nathan Stratton at the 2021 Rasa Summit https://rasa.com/summit/

Couch DB/PouchDB approach for hybrid mobile applications

Ihor Malytskyi

This document discusses using CouchDB and PouchDB to address common problems that arise in mobile application development. It outlines typical mobile app architectures that involve separate server, frontend, native mobile, and database code. This can result in platform-specific code, synchronization issues, and the need for many developers with different technical skills. CouchDB and PouchDB aim to minimize technologies used by allowing data to be stored and synced across clients and servers through a common JSON document format. PouchDB implements the CouchDB API locally so mobile apps can use the same codebase and sync data in real-time and offline through its replication functionality. This hybrid approach reduces platform-specific code and the number of technologies and developers needed for a project

Stream SQL eventflow visual programming for real programmers presentation

streambase

Richard Tibbetts, CTO, StreamBase Systems. StreamSQL EventFlow is one of the most popular languages for Complex Event Processing (CEP), a data management paradigm for real-time applications. Based on a stream-relational data model common to other CEP languages, EventFlow is unique in that it is a visual language. This talk will focus on the design of visual representations for key features including event dispatch, modularity, data parallelism, polymorphism, and dependency injection, and on the co-development of an Eclipse-based IDE along with a new programming language. StreamSQL EventFlow is the primary programming language for the StreamBase Event Processing Platform. Complex Event Processing platforms are used to process large volumes of event-oriented data in real-time, often in latency-critical applications such as securities trading. Combining clustering, messaging, queuing, data storage, and application logic into one system minimizes latency and gives the programmer control over all aspects of the application. StreamSQL EventFlow is an executable visual language for building CEP applications, unlike visual environments designed for non-developers, or architecture-focused modeling tools. The talk will cover experiences overcoming prejudice against visual programming languages, and how critical development tools are to that process. We will also discuss some details of the implementation including the compiler, a visual debugger, and diff/merge functionality.
