I actually think I see how hygienic macros can be gotten out of this now, so it's going back to the shop for one more alteration

I originally wrote this up in 2023; rewrote it twice since then. Each time, it gets a little less incoherent. Make no mistake, it's still incoherent... I'll implement it in an actual programming language at some point - that should make it clearer. Hopefully this year.

A collision of conventions ↔ a convention of collisions A previous generation had a name for this collision-convention ↔ "pastiche" From Italian "pasticcio" ↔ pie-filling of mixed ingredients

You can form valid 8088 machine code as a MS-DOS COM executable using nothing but UTF-8 Braille characters and Windows newlines. This is what it looks like rendered with 2x4 bitmaps. You can view the actual COM file here: github.com/dbalsom/exec... #x86 #asm #assembly #8088 #retrocomputing

Hazy days of summer. This was originally intended as an autumnal landscape, but actually this is the palette of the fields around us at the moment, with all their hay bales 💛 #landscape #autumn #summer #watercolour #watercolor #harvest #painting #abstractart #art | karinacoghlin.com

A gentle abstract landscape in late summer / early autumn hues and cloudy sky.

Printed Circuit Something I made using a variety of filter effects in GIMP, including overcompression, pixel sorting, and edge detect among others. #GlitchArt #AbstractArt #DigitalArt #GeometricArt #PixelArt #Retro #GIMP #Art

Pattern of chriss-crossing horizontal and vertical lines of different colors grouped into clusters and sometimes in a mesh pattern like printed circuits, with a black background

"Claude solves decades-long open problem about computational power of experimental programming language" is far too sensationalist a headline. "Random nerd uses Claude Code to debug a compiler no one really cares about" is much better. #esolang #esolangs #proof codeberg.org/catseye/Burr...

Screenshot showing the history of the Burro programming language.
2005: The author, already familiar with brainfuck and starting to learn about group theory and seeing some similarities between them, gets some ideas about how they could be combined.
2007: Burro language version 1.0 is released. Its documentation can still be found in the file doc/burro-1.0.md.
2010(?): It is noticed and pointed out by ais523 and others that the set of Burro 1.0 programs does not actually form a group.
2010: Burro language version 2.0 is designed and released, along with a proof that its programs do form a group, and a proof that the language is Turing-complete.
June 2020: A more mathematical explanation of the sense in which Burro programs form a group is written up. It can be found in the document The Sense in which Burro Programs form a Group.
July 2020: It is noticed and pointed out (by whom?) that the proof of Turing-completeness distributed with Burro 2.0 is incorrect — it only holds for very small Turing machines. In response to this, a new extensible conditional idiom is developed for Burro code, with the aim of supporting a correct proof of its Turing-completeness.
2025: A minor variant of Burro called Kondey — basically a syntactic sugar for the extensible conditional idiom — is designed, again to support the construction of a new Turing-completeness proof.
June 2026: Tooling for working with Turmac, an interchange format for Turing machines, (version 0.4), is commingled in the source tree, as further support for a Turing-completeness proof.
July 2026: A proof that Burro is Turing-complete was found using Claude Opus 4.8.

This whole damn time Ive been watching all these ICE pogroms, Ive been wondering like, what the hell is this going to do to timber and ag. Are we just not gonna plant trees and harvest crops? And NOPE. They won't target the farms, nurseries, or tree planting ops. Because that'd piss off the money.
