Tool: Mad House — Usborne Creepy Computer Games

Via Hacker News I learned that UK publisher Usborne published free PDFs of their 1980s Computer Books, some of which I remember working through on my Commodore 64 as a child.

These were so great! Beautifully illustrated books with fun projects made up of code you could type into your own machine.

I remember playing "Mad House" typed in from the 1983 book "Creepy Computer Games", so I fed that PDF into Claude and had it build an interactive version of that game in JavaScript and HTML:

Build a vanilla JS artifact that exactly recreates the game Mad House from this book, make sure it's mobile friendly and has a suitable retro aesthetic

The most frustrating failure mode right now is that people submit issues that are not in their own voice. They contain an observed problem somewhere, but it has been thrown into a clanker and the clanker reworded it and made a huge mess of it. Typically, it was prompted so ...

On the <dl>

I learned a few new-to-me things about the <dl> element from this article by Ben Meyer:

1. A <dt> can be followed by multiple <dd>
2. You can optionally group the <dt> and <dd> elements in a <div> for styling - but only a <div>.
3. You can label them using ARIA.
4. They've been called "description lists", not "definition lists", since an HTML5 draft in 2008.

So this is valid:

<h2 id="credits">Credits</h2>
<dl aria-labelledby="credits">
  <div>
    <dt>Author</dt>
    <dd>Jeffrey Zeldman</dd>
    <dd>Ethan Marcotte</dd>
  </div>
</dl>

Here's a useful note from Adrian Roselli on screen reader support for description lists.

Research: pydantic-monty investigation

It's been a few months since I last poked at Monty, the sandboxed subset of Python implemented in Rust. I had Claude Code look at the most recent release.

Importantly the max_duration_secs, max_memory, max_allocations, and max_recursion_depth settings all appear to work as advertised.

We have the ability to use compute resources to support our proprietary AI applications (such as Grok 5, which is currently being trained at COLOSSUS II), while also providing access to select compute capacity to third-party customers. For example, in May 2026, we entered into Cloud Services Agreements with Anthropic PBC (“Anthropic”), an AI research and development public benefit corporation, with respect to access to compute capacity across COLOSSUS and COLOSSUS II. Pursuant to these agreements, the customer has agreed to pay us $1.25 billion per month through May 2029, with capacity ramping in May and June 2026 at a reduced fee. The agreements may be terminated by either party upon 90 days’ notice.

How fast is 10 tokens per second really?

Neat little HTML app by Mike Veerman (source code here) which simulates LLM token output speeds from 5/second to 800/second.

Useful if you see a model advertised as "30 tokens/second" and want to get a feel for what that actually looks like.

[...] in the last 10 years I’ve learned to really love and respect CSS as a technology.

So I decided years ago that I wanted to react to “CSS is hard” by getting better at CSS and taking it seriously as a technology, instead of devaluing it. Doing that changed everything for me: I learned that so many of my frustrations (“centering is impossible”) had been addressed in CSS a long time ago, and that also what “centering” means is not always straightforward and it makes sense that there are many ways to do it. CSS is hard because it’s solving a hard problem!
