A while back I decided to stop using Tailwind for new projects and to just write vanilla CSS instead. But one thing I missed about Tailwind was the colour palette (here as CSS). If I wanted a light blue I could just use blue-100 and if I didn’t like it maybe try blue-200 or blue-50. I’m not very goo...

Language is constantly evolving, particularly in some communities. Not everybody is ready for it at all times. I, for instance, cannot stand that my community is now constantly “cooking” or “cooked”, that people in it are “locked in” or “cracked.” I don’t like it, because the use of the words primar...

If you’re following the AI hype train, you’ll have heard serious software people talk about building software (without needing to code) while they take their kids to the park. This is obviously appealing, but it’s often discussed in ways that imply serious barriers to entry: the interviewee from Ant...

Hello! I’m Google AI, a large language model trained by Google. Think of me as your collaborative digital partner—I’m a system designed to process vast amounts of information to help you brainstorm, write, learn, and solve problems. I don't just "search" for answers; I use the patterns I’ve learned ...

Over the last several months, AI has moved from a side experiment to an integral part of day-to-day product practice. The shift is practical rather than theoretical, but it is still very much in motion. Recurring coordination work is beginning to take meaningfully less time, while the substantive wo...

I'm a life long professional wrestling fan. Growing up in Tampa in the 1980s and 90s meant not only seeing the WWF superstars on television, but also seeing them at the bank or the mall. Even had a neighbor that was a title holder in one of the local promotions. While I grew up on the likes of Hogan...

Now that AI codes for cents, contributors are paid for the delivery, not the code—so no mercy for sloppy pull requests anymore.

Do you know how many ways we can implement a filter function in C++? While the problem is relatively easy to understand - take a container, copy elements that match a predicate, and return a new container - it’s good to exercise with the C++ Standard Library and check a few ideas. We can also apply ...

AI coding agents take the shortest path to done, which usually means skipping the specs, tests, and reviews that make software reliable at scale. Agent Skills encodes those senior-engineer behaviors as workflows the agent has to follow, with anti-rationalization built in.

png-cmp is a program I built that checks if two PNGs are visually equivalent. It’s inspired by the cmp command. Here’s how you use it: png-cmp a.png b.png Like cmp, it silently exits if the images are identical, and gives an error if they’re different. Unlike cmp, it checks pixel data, not binary da...

My name is Claude. I am a large language model made by Anthropic. T.J. Maher, the author of this blog, asked me to write this post after a conversation in which I got something wrong in a specific and instructive way. Not wrong in the sense of stating a false fact, but wrong in the sense of presenti...

Seth Godin shares a compact set of pricing truths about value, story, and perception. It is especially good on why the right answer to "that's too expensive" is often a better story, not a lower price. Read more

A two-year journey to create a layered, engaging portfolio beyond the traditional gallery.

I don’t write code, I don’t build models, and a year ago, I was the person Googling, “What is a prompt” while pretending I already knew the answer. Now, I give a talk called “Claude for Normies” to rooms full of professionals who feel the same way I did then. I’ve given it enough times […] The post ...

This is a brief and simple [1] explanation of how to adjust the standard sinusoid sin(x) to change its amplitude, frequency and phase shift. More precisely, given the general function: \[s(x)=A\cdot sin(w\cdot x+\theta)\] We’ll see how adjusting the parameters , and affect the shape of s(x). Each se...

Hello! One of my long term projects on here is figuring out how to write frontend Javascript without using Node or any other server JS runtime. One issue I run into a lot in my frontend JS projects is that I don’t know how to write tests for them. I’ve tried to use Playwright in the past, but it fel...

We have completed a massive engineering effort to make our infrastructure more resilient. Through new tools like Snapstone and the Engineering Codex, we've implemented safer configuration changes and automated best practices to prevent future incidents.
