A highly coordinated swarm of 20-something engineers posting about a little-known Waterloo AI startup called Polarity . By the time the fellowship wrapped, Polarity had generated over 18 million organic impressions across LinkedIn, X, and Instagram, flooded their pipeline with demo calls from…
I was talking to Mike Bird , who podcasts about AI tools. He asked me if I was using Hermes. "Of COURSE! Everyone knows HERMES. Who doesn't love a good... Hermes!" I said, slyly googling under the camera. Soon, I was having PTSD flashbacks to my experience with OpenClaw. Setting that up felt like getting a Roomba to stop trapping itself under the couch. I eventually got it working out of pure…

Last night, I was rejected from yet another pitch night. It was just the pre-interview, and the problem wasn't my product. I already have MRR. I already have users who depend on it every day. The feedback was simply: "What do you even need funding for?" I hear this time and time again when I try to grow my ideas. Running lean is in my DNA. I've built tools you might have used, like…
I was working on a project the other night, using Google's Gemini to help brainstorm a technical plan. If you've used it recently, you've probably seen the "Canvas" feature. It pops up on the right side of your screen, rendering code and text beautifully. It looks great.

I have never been a gamer. The most I've played was Super Mario Bros (the original). I then took a break for a decade or two and spent a few weeks with Simcity 4. All that changed when I got Google Cardboard.
The difference between two sequences A and B can be compactly stored using COPY/INSERT operations. The greedy algorithm for finding these operations relies on an efficient way of finding the longest matching part of A of any given position in B. This article describes how to use a suffix array to find the optimal sequence of operations in time proportional to the length of the input sequences. As…
Using a locality sensitive hash, you can mark duplicates in millions of items in no time.
Walkthough of reading and interpretting a TrueType font file in a few lines of Javascript.
How do you measure the "sortedness" of a list? There are several ways. In the literature this measure is called the "distance to monotonicity" or the "measure of disorder" depending on who you read. Here, I propose another measure for sortedness.
