We’re excited to announce something new we’ve been working on, which we are calling EchoCasts. As our first EchoCasts offering, we present a free screencast series called Creating An xy-Plane Vue.js Component. We think this series will be helpful for a wide range of JavaScript developers, whether they be new to Vue, new to JavaScript frameworks, […]
Set Theory And Russell’s Paradox
In a previous post, we looked at notation for functions and sets. In that post, we knowingly skirted around the definitions of some key terms, and here we’re going to look at why this was necessary. To recap, here are the key terms from our last discussion that we did not define rigorously, along with […]
Function And Set Notation
In a recent post we talked about the definition and nature of functions and explored how the term function differs in meaning within the contexts of math and programming. Most notably, we saw that functions in the mathematical sense are more akin to associative arrays in programming than they are to functions in programming. This […]
What Is A Function
One of the most ubiquitous concepts found in programming languages is that of a function. There are many things that functions can do, and this makes it hard to come up with a concise definition of a function, even if we narrow our focus to a single language. Functions In A Programming Context Consider some […]
My First Peek At Angular 2
In the past year or so, I have been learning AngularJS (aka Angular 1) and have found it intuitive and enjoyable. I used it on a few different projects, both for clients and for fun. When I first began looking into Angular 2 (aka just plain Angular as opposed to AngularJS, which is now a […]
Pre-populating Checkboxes in Gravity Forms
We previously wrote about how you can pre-populate input values in Gravity Forms. The comments for that post revealed something obvious that we missed – the technique does not work for checkbox fields or any other fields that have pre-defined choices, such as radio buttons and dropdowns. For this blog post, we are focusing on […]
Unit Testing With PHPUnit
Merging code, especially when authored by multiple people, can lend itself to a lot of risk. As a code base grows, there may be an underlying feeling that more bugs exist than we can find by digging through our code editor or our application’s various screens. Unit testing is a process that lets us test […]
Creating A RESTful WordCamp Speaker Finder App
We’re creating a YouTube series that walks through the process of building a WordCamp Speaker Finder app using HTML, CSS, JavaScript, and jQuery. The video series is free to watch, and does not require advanced programming know-how or specialized knowledge of any framework. We have broken the series down into small, digestible episodes. We plan […]
Keeping A Personal Score Card
Back in 2011, I made a decision to take a break from teaching. This now-distant decision marked the end of a 7-year era in my life that I began by moving across the country from Tennessee to Arizona for graduate school in 2004. After studying for 2 years, I began a faculty position at Northern […]
Using the “At Least One” Rule
When I used to teach math, one thing that came up a lot in probability and also in proofs is the “At Least One” Rule. In essence, this rule states that “Every P is Q ” and “At least one P is not Q ” are negations. As an example, imagine we are tossing a […]
