I think what really made it connect tho was the fact I originally wrote:
done [n^2 continue]/[n^2 done]<br>[Halt]/done []/continue<br>

refactoring that to just
done [n^2]/[n^2 done] [Halt]/done<br>

feels like a holdover from Factran just dropped way in my brain. I am so used to every condition needing a dual countercondition I just reflexively wrote ever rule in pairs (including my math operations).

Implemented a little program to print the binary value of a number:

n^92

[.1 B0]/n^128 .0 @B0
[.1 B1]/n^64 .0 @B1
[.1 B2]/n^32 .0 @B2
[.1 B3]/n^16 .0 @B3
.\s
[.1 B4]/n^8 .0 @B4
[.1 B5]/n^4 .0 @B5
[.1 B6]/n^2 .0 @B6
[.1 B7]/n .0 @B7

I've been thinking about some stuff, maybe you have come across this before or have some insight.

But I was thinking of allowing negative(signed) amounts.

So like n^-4 n^4 would yield 1/1, or identity [].

I'm not really sure if it's a good idea or not, but it's something that's like RIGHT THERE, I feel like it might go to fun places, has a way to indicate the "lack of something".

Just thought I'd share that idea with you, not sure if will implement or not, seems maybe more of a curiosity. I don't know how this will impact matching X)

From the perspective of counter machines, signed counters can work. But it breaks down pretty badly if you allow it in Fractran's encoding scheme.

It means allowing fractions in the bag (2-1 = 1/2), it also opens a can worms around what [...]/x^-1 means. When I was messing with recipe books, I quickly found I needed <0, =0, and >0.

in reply to ... and and and and ...

Also, the counter machine construct when using >= as your comparison operator can handle a case stock Fractran cannot: 0 items in the bag. It's pretty easy to do something like [...]/x^0 when x^0 is not compressed to the same "location" (in this case 1) as y^0.
in reply to ... and and and and ...

Basically, if you want to experiment with matching behavior beyond just positive counters (as FRACTRAN cannot match on 0 items, they all map to 1), then you have to engage with the underlying computer system fractran encodes: counter machines.
in reply to ... and and and and ...

I think until I have a clearer idea of what a negative count match "means", I'm not going to push further, but have you come across something that works that way with counter machines I could use to try this idea? Or do they always have all the different comparison operators to handle that sort of things?

I was just looking if petri nets and that sort of stuff had ways to handle the lack-of-something and there isn't much written about that.

Logic systems don't like the idea of "this is not true". Generally, you lean on disjuctions "f(x) and nop(x) or h(x)" rather than not f(x) and h(x). This is why for my check on the hailstone function I phrased it like this:
done [n^2]/[n^2 done] [Halt]/done<br>

I have to construct a token representing a choice, the destroy it to represent its negation. With a "not" in Fractran, I could have written:
[Halt]/n^0<br>

However, due to Fractran's encoding, this is the same as [Halt]. *^0is always True.
in reply to ... and and and and ...

This is kinda what I meant by "shuffling control-flow". As you have to create resources to take a transition, then consume them to make that transition fail.
in reply to ... and and and and ...

This is also true of Petri nets. They are all about tokens flowing through a system. It creates a contradiction in the model if a transition can assert you "don't have any tokens".

How can you have a token representing the lack of tokens?

in reply to mx alex tax1a - 2020 (6)

@atax1a yup, and that kinda lead me down the rabbit hole of Type-4 grammars (which there seems to be exactly one citation for so). @june had built a little bit-oriented stack machine. And it could only make decision on 1 as 0 wasn't "in the language". However, I discovered you could expand the language using an encoding scheme such as 1 -> 10 and 0 -> 01.

Basically, you always have to encode unmatchable information into the system by expanding your symbol set.

sheeeeeeeep.art/finite-choice.…

in reply to ... and and and and ...

the other option we see is to allow transition on no tokens, analogous to the difference between DFA and NFA
in reply to mx alex tax1a - 2020 (6)

@atax1a and that's where you have to break from strict Fractran cause 2^0 = 3^0 = 5^0 = ... = 1 and then everything implodes.
in reply to ... and and and and ...

okay thanks for all this, it makes it all pretty clear, I don't need negative exponents, too much noise to an otherwise OISC 😀

I've been implementing a tropical arithmetic evaluator and I had to make a GDC() implementation and it looks so cute

I would say 0 is doable with only >=, but negatives are a clusterfuck that introduced special cases and 2 or 3 way logic. Open topics for anyone looking to extend Rejoice.

yes? unless there's a game specifically designed to prevent you from doing so, I'm pretty sure you can beat any game where you can turn by moving in any direction


RE: social.treehouse.systems/@danc…

April 1st is over.

However, we really do want to port Haiku to the RK356x.

In fact, there is progress on porting Haiku to arm64 and it seems to be making good progress: discuss.haiku-os.org/t/arm64-p…

We have NO PLANS to deprecate our ALARM-based Linux distro. 🙂

#pinetab2 #haikuos


We want to port Haiku to the RK356x platform 🙂

It's a long term plan but once Haiku port for RK356x is done and ready, we'll:

- Deprecating our ALARM-based Linux distro in favor of Haiku.

- All new PineTab2 will ship with Haiku instead of traditional ALARM-based Linux distro.

- Existing users will still remain on ALARM, however there'll not be any updates (user will receive "there is nothing to do" when they tried to update it)




Haven’t checked if he really said this; it’s just a nice sentiment.

The Vampire Rabbit of Newcastle upon Tyne


Newcastle upon Tyne is best known for its proud history of industry and invention, its famous football club, and its vibrant nightlife. Many people who walk the busy streets of the Toon, are unfamiliar with its dark side: real life witch trials, public execution and dissection, and of course, the vampire rabbit.

Unlike the former two very dark tales from Newcastle, the Vampire Rabbit is of a lighter order. More of an interesting conversation piece for those who seek it out or come across it by accident...

shouldn't the metric one be the smaller one?
it's the one that uses si prefixes correctly and the bigger one has weird factors between ranges o.o

These are our Aussie animals seeing themselves in a mirror!

I wouldn't be surprised if the magpies did recognise that they were looking at themselves. The two that come up to the mirror near the end of the video are mother and adolescent child.

in reply to Muse

@Muse I've always has a full length mirror for the pets who have graced by life, including a beloved rabbit, and fish swimming inside an aquarium. The Secret Life Of Plants: "GEMMA", the Weeping Fig Tree, has that same full length mirror by her and a window. It provides more sunlight, and perhaps she can look at herself. Who knows? Maybe she thinks the reflection is another tree, and it's her friend and companion. 😉)

@foaylward

Like solar, wind is also broadly distributed. I'm still awaiting an effective home wind turbine. Even at 0.1 kWh production it would make a difference at home, in addition to reducing pressure on the grid and its associated infrastructure costs.

in reply to Albert Cardona

agree completely. The hardware is a bit more expensive, I believe, but getting cheaper. I had a neighbor in Arizona twenty years ago that had an at home wind turbine, so clearly feasible.



"My friend Malcolm told me a story about pronghorns recently, the North American creatures sometimes confused with antelopes. They can run at speeds of nearly sixty miles an hour, much, much faster than any of their existing predators. Some biologists think they're still outrunning the dangerous species that went extinct at the end of the Pleistocene, specifically the cheetahs that existed on this continent. And then Malcolm asked what each of us is still outrunning and whether we can tell when our predator has been extinct for ten thousand years."

For a while now I've been wanting a generic notation to explain various things on my wiki(tropical arithmetic, multisets, other programming languages, ternary logic, primes, etc..) and I found a PL design I really enjoy writing.

It lands in a weird place, I feel like it might be the only concatenative language without a stack? As far as I know anyways.

I took a day to implement it, and shoved it into a little interactive playground. I have yet to populate the examples.

“The amount of untaxed wealth hidden offshore by the richest 0.1 percent exceeds the entire wealth of the poorest half of humanity (4.1 billion people), according to a new Oxfam analysis published on April 2, 2026, ahead of the 10th anniversary of the Panama Papers.

The findings show that, a decade later, the super-rich continue to exploit offshore systems to evade taxes and conceal assets, highlighting the urgent need for coordinated international action to tax extreme wealth and end the use of tax havens.

An amount of $3.55 trillion in untaxed wealth was stashed offshore in tax havens and unreported accounts in 2024, according to Oxfam’s estimates. “This sum exceeds the GDP of France and is more than twice the combined GDP of the world’s 44 least developed countries,” a statement by Oxfam noted.“
