Howdy y’all!

Like many of us, I’ve become the family IT person for a lot of situations.

At work, we have a livestream show called Rubber Duck Thursdays where we talk about open source and code each week.

Like many people in tech nowadays, I use LLMs at work.

I love you so much.

My maternity leave is officially over!

I tried playing with the new Sora 2 model this week.

I’ve written before that I use Obsidian as my “second brain” tool, but lately I’ve been experimenting with my setup to make it better, particularly on mobile.

Flash back to Spring 2020, when we were all confused and uncertain about what the world was going to look like, and unsure of how we would stay connected to each other.

I’ve written before about how I am sometimes haunted by my own side projects that I should finish, but I also want to pursue a shiny new thing instead.

I learned about Fliiip Book on the internet recently and it’s pretty cool.

I was going through some old folders on my laptop and found some old code from my old React Training teaching days for visualizing how component trees in React work, and turned it into its own standalone web app!

Right now, I’m still on maternity leave, with my 4 month old and my 2.5 year old in tow.

I built and released Ductts, an app for tracking how often you cry!

So, I know that I shouldn’t be on my phone as much in front of my toddler but… I do look at my phone.

I watched a video recently, that had text fading away.

This week I went to and spoke at the latest Chicago mechanical keyboard meetup, called That Windy City Keeb Meet 2025!

I learned today that you can have GitHub Copilot pay attention specifically to the current changes in your repository!

When you use GitHub Copilot online, you can add personal instructions to your responses so that it always responds in a certain way.

I posted about my project Better Security Questions recently and several people mentioned that instead of actually answering security questions, they generate a random answer in their password managers and use that random answer to log in.

Whenever I release a project publicly, people always have feature requests for it.

Something that always bugged me about this blog is that the open graph/social sharing images used this for every single post: I had made myself a blank SVG template (of just the rainbow-colored x pattern) for each post literally years ago, but didn’t want…

I wrote a Node script recently that installed Puppeteer, and that script ran at build time for a website I was working on.

Recently, a friend of mine who works for The Alinea Group told me about a project they wanted to run for the restaurant’s 20th anniversary popup event.

The things that my 2-year-old says are so dang cute, and also a real reflection of how I speak.

I built PocketCal over the past couple months, and it was a really interesting learning experience!

When you have an array that has multiple dimensions, it might be referred to as a 2D or 3D (etc) array.

There are several HTML <input> tags with types for dates and times: input[type="date"] input[type="datetime-local"] input[type="month"] input[type="week"] input[type="time"] When you use these inputs in a supported browser, you might notice that there’s a…

I just had my second baby!

Nearly 6 years ago, I helped Stack Overflow start their newsletter!

I use VS Code for… code, heh.

GitHub supports dark mode and light mode, and as developers, we can make our README images look great in both themes.

Normally, when I get an electronic device, I use it and wear it down until it’s nearly unworkable.

It feels like everyone’s talking about MCP (Model Context Protocol) these days when it comes to Large Language Models (LLMs), but hardly anyone is actually defining it.

Unlike my first baby where I was going into things very ignorantly (I would tell people, “oh, hey, if my new baby is chill I’ll do this podcast recording, no problem!”

On my blog, I have everything as a set width.

In case you missed my mentions of it before/on the internet, I’m pregnant again, and due relatively soon, and… man I am feeling weird about it.

This is kind of an incomplete thought that I’ve been thinking as I see people boycotting very convenient things like Amazon and Target and even TikTok: I think it is an incredibly good thing that people are doing this.

I need to learn to (over)think less.

I wrote about building my digital typewriter in the past, and it has worked fantastically for me so far!

Let’s make it so you can record a demo (assuming you recorded it in VS Code) once in dark mode, and then convert that into light mode, in a single command!

I was streaming this past week and there was a good question about re-ordering Git commits that I thought would be worth sharing here.

I recently was messing around with the HTML <dialog> element.

I built a GitHub Copilot Extension recently that made me unreasonably happy for one major reason: it made my old startup’s app, Brainstory, come back to life, in a very small way!

Did you know that GitHub Copilot can edit files directly?
