It seems like a lot of websites these days are equipped with a Chatbot. Itโ€™s used for customer service, simple Q/A, and more.

As chatbots have grown in popularity, so have the number of different frameworks that can be used to implement them.

In this blog, we will explore one of these frameworks, Rasa. First, Iโ€™ll cover some of the basics of chatbots. Then, Iโ€™ll explain how to write a simple Chatbot using Rasa, and weโ€™ll highlight some of its additional functionality as well.

Apple Silicon for Dev

Apple Silicon for Development

Lou Mauget Articles, Development Technologies & Tools, Programming, Python Leave a Comment

In June, Apple announced a two-year transition from Intel to Apple Silicon for the iMac and MacBook line. I knew Apple had lost their mind. But, before Christmas, I owned my very own chunk of Apple Silicon living in an attractive milled-aluminum case.

In this article, I’ll discuss the Apple M1 silicon-on-a-chip (SoC) used as a software development computer. I’ll cover installation, and I’ll also talk through running apps that support development on my M1.

This is a tutorial for how to use the VS Code Remote-Containers extension to containerize your development environment.ย First, I will discuss my reasons for separating my programming environment and why virtual machines didnโ€™t work.ย Then, Iโ€™ll show a simple example using a containerized Python development environment.ย Finally, Iโ€™ll give you my reasons why containerizing the development environment fits what Iโ€™m looking for in a solution.

Expression Parser with Antlr4

An Antlr4-Based Expression Parser

Lou Mauget Articles, Development Technologies & Tools, Java, Programming, Python 1 Comment

In this blog, weโ€™ll present a simple arithmetic expression parser implemented through an Antlr4 parser generator. It will be able to take in an input string (such as 2+4+-4+-2*10%9*7) to produce the result (-12.0).

You may be thinking, “Great, but whatโ€™s the point?” Well, to answer your question, as simple as this example may seem, the principles involved actually extend to use cases such as DSLs, transpilation, and anything else expressible by grammar rules.

This post has two parts. In part 1, weโ€™ll discuss the background components of a parser. In part 2, weโ€™ll cover building the demo and running it. If you already understand grammar parsing, you could skip part one.

A Vue of Python

Earlier this year I blogged about creating a Lean Mean Vue Machine called Quotes on Demand. The application was a fully featured CRUD application served from a NodeJS server and had a self contained VueJS front end.

But wouldn’t it be a nice test to see if that same Vue application could switch over to another API, say something like a Python web server powered by Flask?

In this post, we will create a Python web application that will have 100% parity to an existing NodeJS web application. This will enable an existing VueJS front end to connect to the application with no additional code changes in the user interface code.
