Blog postOne of the things I most enjoy about Jekyll1 is writing my blog posts in Markdown. I love not worrying about HTML and just letting Jekyll generate it for me when a post is published. Using Liquid tags directly in Markdown is also helpful, as I can define sitewide or page-specific variables and then replace them during site generation. This is a really useful capability that I wanted to take advantage of to output Markdown for use in other sites. Places like Medium and dev.to allow you to post

Blog postIn 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 last node in the list points to the first node in the list, effectively making the list circular. Circular doubly linked lists are interesting because they allow you to continuously move through

Blog postIn 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 for operations, and as such, have generally poor performance. One way to improve the performance of linked lists is to add a second pointer on each node that points to the previous node in the li

Blog postLast 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. Is it a class? Is it a function?

Blog postBack 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 out I was well short of 52 ideas. I dug through some half-written chapters what would eventually become Professional JavaScript and found a lot of material on classic computer science topics, including data structures and algori

Blog postIt’s 2018 and somehow women are still getting paid less than men, even in supposedly progressive industries like software.[1] Whether that be from companies offering women less than men for the same position, women being less likely to negotiate or less successful in negotiations, or any of the other myriad reasons, the results are still the same: women make less than men for the same job. That’s something that shouldn’t be happening in today’s world and it’s up to us (read: men) to step up a

Blog postIf you’ve worked on a Node.js command-line program, you were probably faced with the extraction of command line arguments. Node.js provides all command line arguments in the process.argv array. 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 running the JavaScript file The path of the JavaScript file being executed So the first command line argument is the third item in -
Blog postThis 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 to determine when a new post appeared on my blog. I figured I would never be able to build my own system When I moved this blog from the dynamic Wordpress to the static Jekyll[1

Blog postNot 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 using GitHub pages was that I could schedule posts to be published later. Jenkins was run every morning and new posts were automatically published without manual intervention. (Jenkins was a

Blog postIf 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 without understanding their origin story, but I always find it interesting to hear about how it all started.
I recently realized that I’d never shared the origin story of ESLint.
