Smaller Code, Better Code
I was enjoying some pizza the other day with some buddies that know a bit about my research and understand where I am coming from with regards to my own computing aesthetics. They understand that I have always pushed for the smallest code that I can get, and to simplify

Two kinds of vibe coding
Back in 2009 I posted a simple Mandelbrot fractal viewer on the web: a single HTML file with inline Javascript. Just 329 lines of code, each pixel a tiny table cell. Click to zoom. Watch it iterate. That was about it!

In June 2000, while visiting Korea, I did a fun hack that clearly illustrates the original and true meaning of the word "hacker".

The unbearable slowness of AI coding
I’ve been coding entirely with Claude Code for the past two months. At first it was exhilarating. I was speeding through tasks. I was committing like mad.

Async2 – The .NET Runtime Async experiment concludes
The .NET team has been working on a new experiment called async2, which is a new implementation of the async/await pattern that is designed to be more efficient and more flexible than the current implementation. It started with green threads and ended with an experiment that moves async and await to the runtime. This…

Root cause analysis? You're doing it wrong
If you have arrived here, you should know this is an early draft containing mostly unedited stream-of-consciousness crap because I have found it difficult to structure this topic. My latest attempt is to split this information up into multiple separate articles.

Writing a blatant Telegram clone using Qt, QML and Rust. And C++
This was a fun project for a couple of days, but I will probably shelve it for now so I can continue what I was already working on before. Read on to follow along with my journey. Spoilers: I didn’t get very far.

Bringing a dynamic environment to C: My linker project
I'm writing a linker. It's an unusual linker. It's focus is not on producing executable files. Instead, its focus is to facilitate rapid iteration on a program without having to re-link or re-open it after making changes. It is hot-loading of code at an object-file granularity.

The social side of science seen in the research on programming language quality
I love science. Not the “space is beautiful” faux-science, but the process of doing science. Hours spent calibrating equipment, cross-checking cites of cites of cites, tedious arguments about p-values and prediction intervals, all the stuff that makes science Go. And, when it does happen, the drama. I also want us to…

Finding unique items: hash vs. sort
A while back, I was trying to speed up some code which finds unique items in a collection. For example, transforming "AABBADCAB" => "ABDC" . There are two ways to do this efficiently - one is based on sorting, the other based on hashing. So, which is faster? I couldn't find the answer, so I ran some experiments and…

Why MongoDB Never Worked Out at Etsy
In 2010ish, we tried to roll out a feature ( Treasury ) using MongoDB. It was an interesting experience. I learned quite a bit in the process. I wrote about what I was thinking at the time here . But for the most part it was an abject failure and Ryan Young wound up porting the entire thing to the MySQL shards which…
