When your database CPU is at 100%, what is it actually doing? Memory stalls, CPU caches, and how radix partitioning makes GROUP BY faster.
Observations from Running stealmybitcoin.com | Pavursec
Last week, I saw an article on the front page of the New York Times website reporting that a critical vulnerability in PHP had been found. The article, and others like it, claimed any attacker could achieve arbitrary remote code execution on any of the million…

Goodhart's Law, but We Already Spent All Our Money
Here is how to make any sports fan angry. Basketball is just a bunch of grown men bouncing a ball and throwing it into a basket. Football is a bunch of grown men running on grass trying to kick a ball
Introducing Adaptive Dark Mode
We’re excited to announce Adaptive Dark Mode in Safari 27.3 beta.
The Little Book of Generative AI Foundations: An Intuitive Mathematical Primer
This book provides a compact, derivation-oriented introduction to the mathematical foundations of modern generative artificial intelligence. Rather than surveying every recent architecture or implementation detail, it develops a coherent route through the idea…
C++26 DIS failed, how does C++ survive?
On October 23, 2026, the unthinkable happened. It was supposed to be a mere formality: C++26 was up for a vote by the ISO National Bodi...
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace, the wiki thing it's part of. Unfortunately you're using a browser (or client library) that my anti-crawler precautions consider suspicious…

i’m a product engineer now. mostly i wait.
Laurie Voss says we’re all product engineers now. I pulled a few months of my own numbers to see what that actually looks like day to day. The code part is basically free. The waiting part is not, and the outer loop is where I spend my brain.
The software industry: annealing, but wrong
In recent months I've heard of several teams with an interesting policy: each pull request should be no more than a few files, and no more t...
Core to core latency depends on the physical address as well as the two cores: every transfer goes through the line's home on the mesh. How I found it, measured it, and used it.
I keep seeing more and more people talk about how ai is going to take our jobs, how fundamentally it has shifted knowledge work from something low-level and ...
The SaaS apocalypse started in October
Software stocks have mostly recovered. Stripe's benchmarks, across 181,000 subscription businesses, turned down in October.
Self-hosted GitHub Actions runners mean that when a job hangs, the first question is always the same: is it me or is it GitHub? So I built one page that answers it. runner-watch reads each runner's process tree and socket table through yeet's system graph, onc…
Almost every text editor on the web is built on contentEditable, an old browser API full of quirks. I built Tasfer on a 2D canvas instead, from the ground up, with peer-to-peer collaboration and no accounts. It is now open source.
Why ctxd: Let the agent grep | ctxd
No Complex Infrastructure and Costs. Why we are building open-source ctxd around regex search, source files and an agent’s ability to follow the evidence.
The release of TypeSafe’s Jev brought attention to so-called decision models. These models are designed to classify predefined choices quickly. Given information, a question and possible answers, decision models return a probability for each option. We use the…
Custom Voices With Qwen3-TTS
Cloning, designing and blending voices with Qwen3-TTS.
Once machines can talk forever, time spent stops being a proxy for value and starts being a symptom that something’s wrong.
After a year, my MacBook battery health is still 100%
AlDente Pro taught me why MacBook battery health management matters. I review charging limits, heat protection, calibration, and long-term plugged-in use to assess its value.
In robotics, price is basically actuator count. Stringman reaches an entire room with four motors, hanging its gripper from lines anchored in the ceiling corners. Working from above, it reaches floors too clutter…

The one where the grim reaper has a web standard in sight.
Yesterday’s hot paper was Sparks of Weight-Space Programming: LLMs can natively read & write neural network weights by Rikiya Takehi, Jayden Teoh, Alex Zhang, and Omar Khattab. The paper (OK, …
Get the C# 15 Skill: https://dometrain.com/free/download-assets-union-types-are-finally-in-net-but-who-cares/ Hello, everybody. I'm Nick, and in this video, I want to talk about the brand new feature called Union Types (or Discriminated Unions by some) that w…
This video examines the amount of location information carried by inaudible background sounds, using the Doppler effect to locate a reference recording within ~100m, and only needing (in some cases) less 1-min of audio. This video raises awareness of these cap…
Postgres 19 is late, and it's AI's fault
Over the past decade, the timing of PostgreSQL major releases has become very predictable: no earlier than the middle of September, and no l...
The experiments that read raw weights and the ones that fix Qwen use completely different techniques.
How do you implement a random-access database when you don't have random-access external storage? - The Old New Thing
You just store it all in memory, in your own program.
