In this video, I demonstrate the tools that I use in my coding environment for this course. There are many alternatives to this particular setup, but in case you are at a loss for what to use, here’s a reasonable option. The tools I am showing you (node.js, atom, p5.js) are free.

In this video, I demonstrate how you can get text input from a user with DOM elements (“input” and “textarea” in combination with the p5.dom.js library.

In this video, I show you how to get text input from a user by loading a text file using the p5.js function loadStrings(). I discuss how a user can upload their own text file with createFileInput() or a “drag and drop” zone.

In this video, I discuss the JavaScript String object, and how to use it to modify and manipulate text in JavaScript. The functions / properties covered are indexOf(), substring(), and length. I look at the p5.js specific split(), splitTokens(), and join().

In this short video I discuss a creative assignment around the topics covered in Week 1 of “Programming from A to Z”.

In this video I introduce Regular Expressions. What are they and how are they used?

In this short video I discuss a creative assignment around the topic of Regular Expressions in Week 2 of “Programming from A to Z”.

In this video I discuss meta-characters: what are they and what role do they play in regular expressions?

In this video, I explain character classes which are a way of matching a selection of characters in a regular expression.

In this video I discuss capturing parentheses and how they are used to create numbered groups that referenced in a find/replace operation.

In this short tutorial, I explain the concept of “back references” and explore how they are used to match the characters previously matched by capturing parentheses (groups) in a regular expression (regex).

In this video, I discuss how to use regular expressions with theJavaScript programming language.

In this video, I discuss another JavaScript function for regular expressions: exec().

This video covers split() – a JavaScript String function, which is used to split a given piece of text into “tokens” based on a “delimiter” as defined by a regular expression.

In this video, I cover the JavaScript function replace(). The function allows you to search for a string (by matching a regular expression) and replace that string.

In this video, I cover the basics of using the RiTa.js library in JavaScript. I look at analyzing text with the RiString and generating words from the built-in RiTa lexicon.

In this video, I cover a JavaScript “natural language processing” library called “nlp-compromise.” I show how you can change the tense of verbs, pluralize nouns, and perform other types of language-based operations.

In this short video I discuss a creative assignment around the topic of Data and APIs for week 3 of “Programming from A to Z”.

Week 5 of Programming from A to Z focuses on about text-analysis and word counting. In this introduction, I discuss different how word counting and text analysis can be used in a creative coding context. I give an overview of the topics I will cover in this series of videos.

In this video, I discuss the concept of “associative arrays” in JavaScript. I look at how JavaScript objects are collections of name-value (or key-value) pairs. This works in much the same as dictionaries in Python or HashMaps in Java. This concecpt will come extremely handy in the coding challenges around word counting.

In this video I discuss assignments and exercises around the topic of Text-Analysis and Word Counting for week 5 of “Programming from A to Z”.

This video introduces Session 6: Markov Chains (http://shiffman.net/a2z/markov). It is part of the ITP course “Programming from A to Z”. A Markov Chain is a broad concept, in this series I will demonstrate it as a means to generate text algorithmically, using n-grams and probability.

In this last video of Session 6, I discuss exercises you can try related to n-grams and Markov Chains (http://shiffman.net/a2z/markov).

This video introduces Session 7: Context-Free Grammar from the ITP course “Programming from A to Z”. A Context-Free Grammar is a set of recursive “replacement” rules to generate text. In this session, I discuss two JavaScript libraries: Tracery and RiTa.js for working with context-free grammars. Finally, I code from scratch basic context-free grammar system.

In this video, I demonstrate how to use Kate Compton’s Tracery library to generate a story from a set of grammar rules.. This video is part of Session 7 of the “Programming from A to Z” ITP class.

In this video, I use Daniel C. Howe’s RiTa.js library to generate text with a context-free grammar (https://github.com/dhowe/RiTaJS). This video is part of Session 7 of the “Programming from A to Z” ITP class.

In this last video of Session 7, I discuss exercises you can try related to Context-Free Grammars.

In this session, I cover the basic steps for building a RESTful API with Node.js. I show you how to install the Node.js framework express how to use routes and parameters to deal with the HTTP GET requests. I also cover what it means for an API to be a REST (Representational State Transfer) API.

In this first video of “Building an API in Node” from the ITP course “Programming from A to Z”, I show you how to create a simple HTTP Server with the Node.js framework Express. http://shiffman.net/a2z/node-api/

In this second video of “Building an API in Node” from the ITP course “Programming from A to Z”, I explain what a REST (Representational state transfer) API is as well as how to use “routes” in Express to process requests made to your API. http://shiffman.net/a2z/node-api/

In “Building an API in Node” video for the ITP course “Programming from A to Z”, I expand on the previous video and customize the routes used in the GET requests using parameters. Data is returned to the client in JSON format.

In this video, I discuss how to work with a very simple database with in the API example using local JSON files and the node.js “fs”(file-system) package.

In this video, I look at how to talk to your API from a web page by building a simple front end client with HTML and the p5.js library.

This is it! The conclusion to the “Build Your Own API” with node.js tutorial from my “Programming from A to Z” ITP class.

In this video, I introduce the concept of “Database as a Service” (DBaaS). I discuss how you can store data in a web application written with client-side JavaScript only. This is the first video in a tutorial series about Firebase. This video is part of the “Programming from A to Z” ITP course.

In this video, I demonstrate how to save data to the cloud using the database service Firebase. This video is part of the “Programming from A to Z” ITP class.

In this video, I demonstrate how to retrieve data from Firebase (Google database as a service product). The example is a high score list but the data can be anything of course. This video is part of the “Programming from A to Z” ITP class.

This video is an introduction to a new topic in my Programming with Text playlist: Chatbots!

In this video I cover RiveScript: a simple scripting language for chatbots with a friendly, easy to learn syntax.

In this video, I use the p5.Speech library for text-to-speech (TTS). The p5.Speech library is an initiative from the NYU Ability Project.

In this video, I use the p5.Speech library for speech-to-text, i.e. speech recognition. The p5.Speech library is an initiative from the NYU Ability Project.

This video introduces a new topic in the Programming with Text playlist: Chrome Extensions!

In this video, I cover Bookmarklets, a simple way to modify run JavaScript code to modify browser content via a bookmark button.

In this video, I cover “content scripts” for chrome extensions. The content script is a JavaScript file that runs in the context of a web page (and can be used to modify that page.)

In this video, I discuss “background scripts” for chrome extensions.

In this video, I cover “pop-ups” with chrome extensions.

In this video, I show you how to communicate between an extension “pop-up” and a content script with chrome’s messaging API.

In this video, I demonstrate chrome extension “overrides” – specifically the “tab override” which replaces the default page when you open a new tab in your browser.

The chrome extension API is also available as part of a more general “browser extension” API.
