A Sneaky Phish Just Grabbed My Mailchimp Mailing List
You know when you're really jet lagged and really tired and the cogs in your head are just moving that little bit too slow? That's me right now, and the penny has just dropped that a Mailchimp phish has grabbed my credentials, logged into my account and exported

Cottagecore Programmers
Every programmer I know has at some point longingly expressed how “[they] want to work with [their] hands”. Some say they wish they were a carpenter, some want to be in the fields on a farm, some want to raise chickens, or milk cows. It is however inevitable that I either hear someone say it or agree with it at some…

I won't connect my dishwasher to your cloud
This weekend I had to buy a new dishwasher because our old GE died. I bought a Bosch 500 series because that's what Consumer Reports recommended, and more importantly, I could find one in stock. After my dad and I got it installed, I went to run a rinse cycle, only to find that that, along with features like delayed…

Writing a tiny undo/redo stack in JavaScript
I’ve needed this before - a couple of times. Third time I figured I needed something small, nimble - yet complete. And - at the same time - wondering about how to do it in a very simple manner. I think it worked out great, so let’s dig in. Most UIs will have some form of undo functionality. Now, there are generally…

Move on to ESM-Only
Three years ago, I wrote a post about shipping ESM & CJS in a single package , advocating for dual CJS/ESM formats to ease user migration and trying to make the best of both worlds. Back then, I didn’t fully agree with aggressively shipping ESM-only , as I considered the ecosystem wasn’t ready, especially since the…

The Software Engineering Identity Crisis
Many of us became software engineers because we found our identity in building things. Not managing things. Not overseeing things. Building things. With our own hands, our own minds, our own code. But that identity is being challenged. AI coding assistants aren’t just changing how we write software - they’re…

Technicalities of Homeworld 2 Backgrounds
Just kidding. Of course, I have something to say about this. In the company, we look at the art of Homeworld from time to time and bow to the creators of this masterpiece. Once, we talked about how great the background look and how interesting this sketched style is. There is something…some details seem…special to us:

The Lost Towers of the Guelph-Ghibelline Wars
Looks fake, doesn’t it? This implausible Medieval forest of towers, as dense as Manhattan skyscrapers, is our best reconstruction of the town of Bologna at its height, toward the end of the Medieval Guelph-Ghibelline wars. We don’t see many such towers today… or think we don’t, but actually their remnants are all over…

Bitter Lesson is about AI agents
The Race for AI Progress In 2019, Richard Sutton, wrote his groundbreaking essay titled ‘The Bitter Lesson’. Simply put, the essay concludes that systems which get better with higher compute beat the systems that do not. Or specifically in AI: raw computing power consistently wins over intricate human-designed…

Ruby, Ractors, and lock-free data structures
This story is about concurrent data structures in the context of Ruby. The goal here is to demonstrate how true parallelism can be achieved with global mutable state (which at the time of writing, is not supported by built-in Ruby primitives).
