Ken Shirriff (npub1mgq…sjel) Hey Ken. You may not have known this person or his website, but I've just stumbled upon his website (I was actually digging into a machine code chess programme for the ZX81 when this emerged) mentioning a paper you co-authored in 1992. Just thought you might like to know about it, still dormant and rarely visited in these 30 year-old web pages at Oxford.

2026-10-07T22:46:20Z

Sometimes I think of some things.

Academic life is described in a vocabulary that never quite fits me. People defend their dissertations. They survive the defence, endure it, come out the other side. Even the fond accounts keep the grammar of combat: a wild ride, trials, exhaustion, and at the end the relief of having made it. The people involved are remembered warmly, as companions on the road, or more like brothers in arms of a sort... but the metaphor underneath is still an ordeal. Years of intellectual work end as a confrontation to be survived.

What interests me is the assumption beneath this. Agonism is treated as the natural condition of intellectual development, as if opposition, contradiction and overcoming were the forces that drive it. That is Hegelian: negation as the baseline from which everything must proceed. It is one way of meeting ideas. It is not the only one.

I think of it dialogically. Knowledge is a landscape, and I travel through it from one stimulating, edifying outpost to the next, each offering a new vantage point. On the way I meet people, books, arguments, disciplines and ideas that were outside my world until then. Some I reject. Some stay unresolved. Many become part of how I think. The aim is not to defeat the other voice, and not necessarily to reconcile with it. The encounter itself enlarges the world I have to work with.

So what I would want to say at the end is something like: I met hundreds of ideas that were new to me, and I was able to take in so many of them. I am ecstatic to have walked these paths with you.

This is not conflict versus harmony. Dialogue can be rigorous, uncomfortable and transformative. The difference lies in what the other person is taken to be. They are not an obstacle placed in the path. They are part of the path.

That is why "defence" sounds so odd to me. It places the culmination of intellectual development in successfully resisting the other. The dialogical view says almost the reverse: development is being changed by others, with no need for victory, synthesis or resolution at the end. For a defence not only to be delivered, but demanded, expected, assumed to be the only way things can be... that implies the existence of an attack.

The ideal ending is not "I defended my position." It is closer to this: I found things I had never seen. You showed me what I could not have seen alone. Some of it changed how I see. I am grateful that we walked part of the way together.

The question underneath all this is why we so readily assume that intellectual life needs an opponent at all.

And hopefully many more people who stand to play some really good games as well.

A PICO-8 core is under development for the Spectrum Next, meaning the Next will be one of the first computers capable of running actual PICO-8 games on real hardware.

Of course where I said "ZX Spectrum" I was identifying a specific 8-bit computer model that has very little custom design.

Other computers of that era like the Commodore 64 and the Atari 800XL had more complex custom graphics and sound chips.

Search → exists but bloated→ maybe still build it, consider the impact of bloat. Sometimes you go with the bloat.

Search → exists but untrusted→ maybe still build it, consider the security impact of dependencies. Sometimes the risk is minimised and you can deal with a certain amount of it.

Search → exists but bloated AND untrusted→ most likely build it, consider the double impact of bloat and attack surface that should definitely inform your cost/benefit analysis.

zen80 update: improved tests***Apart from the already substantial unit tests, we now have two additional and rather stringent tests:***<li>This test loads the ZX Spectrum 128 ROMs (0 and 1) and runs that machine's initialisation process. Then it shows a statistical analysis of the instruction coverage that's been executed during rom initialisation. (total percentage of different opcodes executed for each instruction group)</li><li>The second big test implements traps as barebones CP/M shims, loads ZEXDOC.COM and runs its extensive stress test (this can be long). </li>

Work is ongoing to support ZEXALL.COM as well, an even more stringent version of zexdoc that also tests undocumented registers and quirks of the Z80, one of the hardest tests known. This will be next, after I'm certain that this passes all ZEXDOC tests without a hitch. So far so good!

RE: Alleged ESP32 so-called "backdoor"The talk where the researchers presented their findings is about undocumented commands found in the ESP32. They presented themselves as civilians, but they also have a consultancy or work for a company called Tarlogic.

Nothing about the talk, and nothing about the Tarlogic article (that doubles as marketing material for their security product) says that they found anything about backdoors, or any malicious commands.
https://reg.rootedcon.com/cfp/schedule/talk/5

Tarlogic
https://www.tarlogic.com/news/backdoor-esp32-chip-infect-ot-devices/

They don't claim that there is a backdoor, they use many conditionals such as "would" and "could", and they say "maybe" but they didn't demonstrate any exploits.

They've shown that they found interesting undocumented functionality, and they are extrapolating that it could possibly be used *somehow*, but they don't really know if it's possible or not.##

Slander in a teacupIt seems that Espressif built in some debugging functionality? Is that a horrible thing? They don't know, but they make sure to promote their own security product to protect you. How nice of them.

You may ask... what's the point of bothering and going through all the hell and pain of designing a new programming language? Have you lost your mind? Aren't there too many of them already? <li>There aren't too many of this one. In fact there is none.</li><li>The journey is the reward, the learning, the interaction of ideas, the dialogical interfacing of old and new, what was and what will be. That's, in essence, creation. And that's, in essence, growth.

What works for human needs and what makes sense to humans is sometimes –and increasingly often so– not aligned with big business needs. And this is probably an understatement.</li>

2025-02-03T17:04:50Z

This is unxgo, inspired and based on Raven Luni (npub16y7…qk6c) 's work at Hundred Rabbits.

https://github.com/ha1tch/unxgo

With many thanks and unreserved admiration for Raven Luni (npub16y7…qk6c) and R E K T A N G L E (npub1z2c…laft) 's inspiring, delicate, and beautifully precise work

My stuff is work in progress, not yet complete, may not compile. May implement a different kind of bitmap graphics system going forward.

My goal is not to offer a competing Varvara implementation on big systems, but to learn the platform and see how much of it I'm able to implement on other smaller systems. Possibly, eventually with TinyGo on microcontrollers, Z80, and the like.

Other work in progress: a DSL that works like a lua layer on top of unxtal called ualunx

The main thing that makes me stay away from the novel as a form of art is that, for all of its potential and its complex beauty at best, it has catastrophically failed at its core mission of warning humanity and helping to avert a disastrous course of action.

Plus3 aims to become a modern and portable disk management tool of +3DOS disk images for the ZX Spectrum +3.

https://github.com/ha1tch/plus3

I'm sick to death of x86-only binaries that only work on some outdated versions of Windows, or installing some weird-arse .NET runtime.

This is #FOSS, and once it's feature complete, it should work natively on Windows, Mac, and Linux on current hardware and OSes.

2024-10-06T22:46:04Z

Sulpher is the little subset of Cypher (Neo4j's query language) that I'm working on.

I added nore examples of queries that can be expressed in Sulpher:
https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part3-basicgraph.md

Here are other graph features that can be accessed via the REST api without need of Sulpher (tSome of these endpoints translate your REST request to Sulpher under the hood)
https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part4-graphoperations.md

In the Misc section there's a bit more interesting code example on how to use these graph things from your own Python application, or from wherever you can hit a RESTful http api. It implements the basics to access the graph data of a group of bloggers, with blogs, posts, tags, and comments.

https://github.com/ha1tch/rserv/blob/main/manual/rserv-manual_0.3.9-part6-misc.md

Hope somebody finds it useful!

Just how incredibly weird, unlikely, and unexpected was everything that was to emerge from the simplest computer design that could possibly work.

Just imagine the world a minute before the Spectrum, a world in which Jet Set Willy, the Horace Series, Jetpac, and Ultimate Play the Game didn't exist. And then take a look at everything that came afterwards.

Just how unlikely.

They're pretty good, no question about it. I'm looking at XBerry Pi, N-GO, ZX TRES. And some others assembled in Portugal by a shop that imports N-GO boards and fits them in a Spectrum 48 case.

However, from a preservation point of view, the last design made by Dickinson is still meaningful and it still makes sense, even if the TBBlue boards made by Manuferhi and others are exact replicas of the Spectrum Next's TBBlue.

The Spectrum Next scene is too frustrating to contemplate giving $$$ to people who bought them to make a profit.

After I'm done with the Speccies of the Americas I'm probably going to get me a few variants of the Spanish-made Nexts, and maybe at some point I'll find a way to buy a Spectrum Next without getting robbed.

Yet another ZX Spectrum game around the general theme of raiding Egyptian tombs, made with ZX Game Maker. And as you would expect, resonances of Abu Simbel are present. For some reason made a little more interesting by the little twist of changing the identity of the hero/raider to a cute cat (Bastet is the name of a deity that was sometimes represented as a cat woman in ancient Egyptian theology)

It's still #caturday after all!

The explosion of ZX Game Maker titles is palpable. Keep them coming, the more the merrier!

A few may look like derivative platform-like based on Game Maker, but I think that's a good thing, as it will hopefully reward and inspire new devs to take their game design skills to the next level, and augur many more years of new ZX Spectrum titles published with increasing frequency.

It feels like a blend of Rainbow Island with Sonic the Hedgehog and a tad of Abu Simbel thrown in, with some Mario Bros-inspired mechanics, and some screens reminiscent of Jet Set Willy.

2024-08-29T02:41:55Z

The implication of GameNGen is that, if a difussion model can learn to be a Doom engine, it can learn to behave and present like any other type of graphically interactive software.

Based on this method, it's not impossible to think that one could create a videogame without any programming at all, but providing all the necessary input data, imagery, and animated behaviour for a model to learn.

Mind you, with enough patience, you could draw it all on a notebook.
