In my previous post, I discussed what changes are necessary to turn a singly linked list into a doubly linked list. I recommend reading that post before this one (if you haven’t already). This post is about modifying a doubly linked list (also called a linear doubly linked list) in such a way that the... […]

In my previous post, I discussed creating a singly linked list in JavaScript (if you haven’t yet read that post, I suggest doing so now). A single linked list consists of nodes that each have a single pointer to the next node in the list. Singly linked lists often require traversal of the entire list... […]

Last week, I tweeted something that got quite a few surprising responses: In 2019, one of the things I’m going to do is stop exporting things as default from my CommonJS/ES6 modules. Importing a default export has grown to feel like a guessing game where I have a 50/50 chance of being wrong each time.... […]

Back in 2009, I challenged myself to write one blog post per week for the entire year. I had read that the best way to gain more traffic to a blog was to post consistently. One post per week seemed like a realistic goal due to all the article ideas I had but it turned... […]

However, the contents of the array aren’t what you might expect. What’s in process.argv? The first two items in process.argv are: The path to the executable... […]

This blog has long featured the ability to subscribe by email, so you could get an email notification when a new post was published. I’ve used various services over the years to achieve this, first with FeedBurner and later with Zapier. As I’m a do-it-yourself kind of person, I never liked relying on external services... […]

Not too long ago I moved this site from a custom setup on Amazon Web Services (AWS) to Netlify[1]. My AWS setup was a bit cumbersome, consisting of a Jenkins machine that pulled from a private GitHub repository, built the site using Jekyll[2], and published the result to S3. The benefit of this setup over... […]

If you’re like me, you probably use a lot of open source tools every day without thinking about how they got started. Few projects share the “why” of their creation: the actual problem they were trying to solve and when they first came across that problem. You can, of course, benefit from open source projects... […]
