Are the costs of AI agents also rising exponentially? (2025)
There is an extremely important question about the near-future of AI that almost no-one is asking. We’ve all seen the graphs from METR showing that the length of tasks AI agents can perform has been growing exponentially over the last 7 years. While GPT-2 could only do software engineering tasks t

What's New in CPUs Since the 80s and How Does It Affect Programmers?
My mental model of CPUs is stuck in the 1980s: basically boxes that do arithmetic, logic, bit twiddling and shifting, and loading and storing things in memory. I'm vaguely aware of various newer developments like vector instructions (SIMD) and the idea that newer CPUs have support for virtualization (though I have no…

Reviewing Steve Yegge's Prediction Record
I try to avoid making predictions 1 . It's a no-win proposition: if you're right, hindsight bias makes it look like you're pointing out the obvious. And most predictions are wrong. Every once in a while when someone does a review of predictions from pundits, they're almost always wrong at least as much as you'd expect…

The string type is broken
My previous article, “We don’t need a string type“, caused a bit of stir. Though the feedback is mixed, there is a common theme of a string being a useful feature. After doing a bit more research I can determine only one thing: most current string types are broken! Many of us believe our strings […]

Zeroing buffers is insufficient
With a bit of care and a cooperative compiler, we can zero a buffer — but that's not what we need. What we need to do is zero every location where sensitive data might be stored. Remember, the whole reason we had sensitive information in memory in the first place was so that we could use it; and that usage almost…

I don't want to learn your query language (2018)
This is a bit of a rant but I really don't like software that invents its own query language. There's a trillion different ORMs out there. Another trillion databases with their own query language.

The repo author, @BenjDicken, created a fun visualization of each language’s performance. Here’s one of the visualizations, which shows Ruby as the third slowest…
