I’ve had a running joke with my wife Dorte for almost as long as we’ve been a couple. I reasoned back in the day that, since she was going to be a doctor — a more reliable source of income than writing about computer games — she should be expected to buy me the Porsche […]

Introducing GPT-6 Astra for developers

Blink and you'll miss it, but there's a familiar creature at 1m59s:

Across the board, Astra has more attention to detail, better understanding of the user's prompt, and can build more sophisticated outputs. In particular, it excels at building 3D models. I've seen it make incredible renderings of gardens, shipyards, animals, cityscapes, even Dyson spheres.

Astra really does believe in putting a red neckerchief on a pelican riding a bicycle.

The previous post discussed the motivation for and application of the rank-trace theorem. This post will give a proof. Suppose A is a real symmetric matrix. The rank-trace inequality says where tr is the trace operator, the sum of the elements along the diagonal of the matrix. Terse proof Here’s the proof in a nutshell: diagonalize A […]

TIL: Using Blender with coding agents on macOS

I've been having fun with Blender in ChatGPT Codex on my Mac recently. Getting it to work with coding agents is really easy: install the full Mac application from blender.org and run a prompt like this:

Use the already install /Applications/Blender to render a scene of a pelican riding a bicycle

In this case I followed that up with these two prompts:

OK add a background and a lot of flair

Then:

OK make it a whole lot better

And got this image, generated using Blender's Python API:

A few weeks ago I felt like it would be fun to see if I can make one of those cheap Chinese CarPlay dongles run something other than the stock firmware. The idea was that rather than just forwarding CarPlay, why not do something more interesting with them? They all work qu...

SpaceX’s turbine blade factory, Fervo’s deal with Google, Delhi’s cheap metro, why recycling is overrated, and more.

This is a gorgeous set of short stories - and a good deal more accessible than some of the heavyweight prose Liu has previously been involved with. Some of the stories contain sentences which are complex jewels to be savoured. What I particularly like is the way he moves between almost-prosaic Earth-bound stories to the the most extraordinary flights of fancy. One story might be set in a…

I got access to GPT-6 Astra this afternoon, so naturally I used it to generate SVGs of pelicans riding bicycles - at low, medium, high, xhigh and max reasoning levels (Astra doesn't support reasoning=none). Then I rendered those pelicans in a comparison grid with GPT-5.6 Sol...

Quite simply, they can no longer be trusted.

Every second, open source shapes our software, yet our view of this ecosystem is surprisingly opaque. How much can you really trust OSS data?

Suppose you want to know the rank of an n × n matrix A, the number of linearly independent rows of A, or equivalently the number of linearly independent columns. There are at least three difficulties. Difficulties in computing rank First of all, rank is not a continuous function of a matrix. Since rank is an […]

In June I purchased this TrueTime XL-AK time server, so I could learn more of the history of GPS-based time.

I received it on June 22, and just 16 days later a similar GPS time server took down Australia's cell service for 12 hours! I made a short video about it but put off digging into the TrueTime... until now.

Over the past couple weeks, I've 'restomodded' this device with a Raspberry Pi, to build a stratum 1 NTP Time server, which I'd like to eventually add to the NTP Pool. I found a way to drop in a Pi 5 and GNSS HAT, display the time and GPS status on the built-in 16x2 LCD, show the status on the bicolor LED, and make this box useful again.
