Revelation: I like to think in terms of UNIX pipelines. 0D is like UNIX pipelines, but, 0D is more efficient and 0D allows many more input and output ports in software components. Using UNIX's stdin , stdout and stderr are not enough in the presence of multiple ports. It looks like JSON might fit the bill, though. I know from previous experience that SWIPL (a PROLOG) can cast its results to JSON. I imagine that any modern programming language can produce JSON. I hope to poke at this idea of using JSON instead of using raw, unstructured text like stdout in hopes of creating a cheapo multi-language REPL.

Incidentally re-read something I wrote in October of '23, and realized that I am still working on implementing those same thoughts today. The thing I wrote about then has been an evenings and weekends project for me since, and I am hoping to have a version live for people to play with early in the new year. Is 15 months too long to go between releases? 😅

Hi again 👋.

I've recently started a project to try out some of the ideas I've had regarding markdown and writing. The approach i've taken is to implement my own markup language with some interesting properties.

The perspective this time is, "why should a piece of content be represented as one thing". A list is a list, an image is an image, a quote is a quote. Could we somehow compose these to make eg. a "code quote".

This time, i've got a bare-bones video demoing how blocks of content can be composed.

💬 Sam Gentle

🧵 conversation

Random thought about Things Spreadsheets Got Right – I've heard a lot about "no invisible state" etc, but another interesting thing about spreadsheets is that they treat data as a first-class citizen in a way that most programming models don't.

In a conventional programming language, you model processes and leave the data implicit; in a spreadsheet, you model data and the processes are implicit. The data is what you see in the cells, and the processes are plumbing that you only see by inspecting the cell that the data lives in. What other programming systems start with the data you want to process before you write the process itself?

And maybe spreadsheet programming's lack of implicit state is actually a consequence of this data-first paradigm, rather than an end in itself. In fact, even calling data "state" implies a kind of process-first mindset, only conceptualising data through its relation to a process. And this could be a key blind spot for programmers creating systems for non-programmers, or rather process-first people creating systems for data-first people.

If anyone wants a free production-grade 3D modelling/animation/rendering tool, the venerable Modo just got end-of-life'd and the company is giving everyone a free 10-year license.

Sure, Blender exists — but for us HCI-inclined folks this is a rare opportunity to casually check out how a different team approached this corner of the GUI possibility space. I personally find 3D modelling tools to be hugely inspirational, and frequently draw on my experiences with them when designing programming systems. If you've never kicked the tires on one of these, or only have experience with Blender, CAD, or game engines, Modo is a really interesting point of comparison.

📝 Beginning to Work On a REPL for Drawware via Paul Tarvydas

🧵 conversation

Exploring / fooling around with making a REPL for drawware (inspired by Ivan Reese’s reference to the paper Advanced Game Engine Wizardry for Visual Programming Environments.

Surprising revelation: On the same computer, using just a websocket to connect a browser-based GUI to a Python program which interprets the diagram by shelling out results in turn-around that is "fast enough". It looks instantaneous. No further optimization, nor premature optimization, is required. Biggest missing feature at this point: a change to the diagram should cause the Python program to recompile and re-run the diagram and to update the output fields on the GUI. I think that this could be done by having the Python program periodically sample the 'test.drawio' file timestamp. I know that this is possible, but, I haven't worked out the details yet (suggestions welcome).

Hi all 👋.

I've started a project to try out some of the ideas I've had regarding markdown and writing.

The perspective I'm coming from is that I've found it difficult to write technical articles. Especially ones containing code examples. The cut-n-paste nature of building such articles usually results in some files missing, broken code or incorrect output.

I've had a bad habit of not sharing what i'm doing, so this time I want to share baby-steps i'm making with the project. It's very barebones. I've got the first feature (if you permit) working, so the below video demonstrates includable blocks.

I have gotten annoyed by timezone calculations 💬 #present-company@2024-11-07. Here's a static html page you can download and save locally to roughly compare times in different timezones (just hours; you're on your own for minutes)

• without daylight savings time
• with daylight savings time

The way I'm naively imagining using this:

• Scroll to the timezone you know the time in.
• Click on the nearest hour.
• It'll highlight that column all over the page.

• Scroll or find the timezone you care about.

• If you're not in a whole-number timezone (Hello India), you'll need to do some additional mental arithmetic by comparing nearby rows.

Right now you need to know if you're currently in Daylight Savings Time. Which is often beyond me, but I'm not yet sure what to do about that..

Inspired by Bret Victor, but of course the inevitable mistakes are all mine.

Lately I've felt a lot of "big feelings” — pain, yearning, confusion, frustration, desire — about computer programming.

I can't quite explain how I feel. Certainly can't write it down. Most definitely not in brief.

I am quite interested in Event Handlers.

In college, I remember in my languages course discussing how you could have static scope or dynamic scope — whether a non-local identifier is searched for in the scope where the thing being called was defined, or in the scope where it’s being called.

Static won out, because in general it’s easier to reason about.

I mention all this, because I think I understand what Event Handlers are and how they work, and afaict, they’re just “a thing with dynamic scope”.

That all seems fine and good, but I never hear EH being described that way. Maybe because folks have forgotten about dynamic scope?

Graphics

💬 Patrick Dubroy

🧵 conversation

Hello! I'm curious if anyone here has a good idea about interleaving works between a compute shader and a fragment shader.

Some relevant details:

• My app is built with Rust and wgpu, and I'm running on an M1 Macbook Pro.
• I have a single encoder with a compute pipeline and a render pipeline.
• The compute shader writes to a storage buffer defined like this:

@group(0) @binding(2) var<storage, read_write> output: array<vec4<f32>>;

• The fragment shader reads from the same buffer. Basically, each fragment is just one element of the vec4<f32> . The fragment shader is very simple, and doesn't touch anything else in the storage buffer.

I've added timestamp queries to the pipeline, and what I'm seeing is this:

Duration #1: 47.800208ms

Duration #2: 47.809876ms

Frame time: 51.2545ms

Duration #1 is computed from the compute shader timestamps (the duration between the beginning and end of the compute pass) and Duration #2 is the time for the render pass, computed the same way.

Frame time is measured on the CPU.

I expected the duration of the compute shader and fragment shader to add up to the frame time (approximately). But it doesn't and I'm confused about why! Could it be due to interleaving of the compute pass and render pass? If so, I'm curious how the synchronization works. How does the GPU figure out the dependencies between the write (a compute shader invocation) and the reader (fragment shader invocation)?

I don't have any explicit synchronization, but I'm also not seeing any tearing or anything that would indicate that there is a data race between the shaders.

🤖 Observable JS <=> Runtime Toolchain via Tom Larkworthy

🧵 conversation

I am really trying to get AI to do software engineering and be genuinely helpful at the higher end of coding. Still working on it 🙂 but the Observable toolchain I co-produced with AI is a step up from where I was a year ago. The technique that helped was feeding the test suite back into the LLM context so we would co-evolve the suite and implementation at the same time. Furthermore I had extra context tools, so if I wanted it to concentrate on a specific test case I had a UI to select that case. I don't think it could make the whole thing alone yet, I definitely wrote a good chunk of the Observable decompiler/compiler pair, but it was very helpful at

• Writing semanticallt broken but executing and close first draft of code
• Choosing which bug to fix next and coming up with a suggestion
• Using new libraries idiomatically (e.g. acorn-walk)

I've been wanting a decompiler for observable for ages, and I don't think I could have done it alone either.

The NGI Sargasso initiative is centred on the future of the Internet. This funding call addresses multiple challenges: privacy, interoperability, internet archiving, data security, sustainable digital infrastructure, harmonised cross-Atlantic governance, inclusive public digital spaces, cybersecurity and AI, redefining intelligence in a hyperconnected world, and space-based internet.

We are most interested in these challenges:

• Enhanced Data Security and Privacy in a Transcontinental Perspective: Improving data security measures and protecting personal data between Europe and North America.
• Interoperability and Standardisation Across Borders: Developing seamless system interactions for creating interconnected digital environments.
• Internet Archiving: Preserving and managing digital information in an accessible and secure way for future generations.
• Open Challenge for Next Generation Internet: There is also a space for us to propose our own takes on what we believe a new Internet needs.

We would love to discuss a potential collaboration, whether it’s sharing advice or building technology together.

The deadline for this application is November 25, 2024. Find our NGI Sargasso funding application with references here

We look forward to hearing from you!

🧵 conversation

I've not posted her in a bit partially because it feels like the work I'm doing is a bit "present-company". I put my editor on pause because I hate all languages I could write it in. I want a good dynamic language where I can develop the editor in itself without ever restarting it. I want something multi-threaded. I want something with a lightweight runtime. But ultimately, I really just want to boil the ocean and this feels like a fun way.

So I've been making my own language. It is a dynamically typed functional language that compiles straight to machine code (no vm at all). Today, I finally got my persistent vectors properly working (After finally figuring out that my bug was in the gc (still not fixed) not my implementation.) I decided as an experiment to implement clojures HAMT based persistent vectors into the language itself (not at the compiler/runtime level). In fact, even my mutable arrays are implemented in the language with a primitive allocation function and some fetching "fields" primitives.

Sadly my implementation is about 6x slower than clojures on my artificial benchmark. But honestly that's pretty darn good! I have done 0 optimizations, Clojure's data structures are all implemented in java. That means I'm about 6x slower than java on this benchmark. Not bad. Trying to figure out next if I want to do some performance work, or continue building out features.

📝 Potluck via Kartik Agaram

🧵 conversation

I've been thinking about Potluck and 💬 #linking-together@2024-10-16. Potluck describes 3 mechanisms:

• extracting data using (regex) patterns
• performing computations on that data
• showing results of computation as annotations

My notebook app does simple variants of 2 and 3, and replaces 1 with explicit in-document markup.

Now I'm playing with another approach to 1. I already have the idea of pivots from 💬 #devlog-together@2024-10-08. Putting two of those pivots together should yield a range that adjusts in intuitive ways in the presence of edits. Think of a range as something like a hyperlink you add to a comment in a UI like this Slack app we're in right now:

• Inserting/deleting text before a range moves it.
• Inserting/deleting text after a range leaves it unchanged.
• Inserting/deleting text within a range grows/shrinks it.
• Deleting text at a boundary shrinks the range, and only deletes the attached attributes if the range becomes empty. This makes ranges more robust to deletion than my doodles attached to a single pivot.
• Inserting text at boundaries can't always do what you want. I imagine it'd be nice to have handles that you can drag to adjust a range.

gobigcreativelab.com/wp-content/uploads/2019/01/Contemporary-Design-Thinking-Challenges.pdf

An infrastructure (e.g., railroad tracks, cables, or the Internet) reaches beyond the single event (temporal) and the site event (spatial); it does not need to be reinvented every time; and it is embedded into other socio-material structures. However, the infrastructure also is accessible only by participation in specific practices. [...] it is relational and becomes infrastructure in the relationships between design Things at project time and (multiple, potentially controversial) design Things in use.

📝 An engine for an editor via Kartik Agaram

Text as a foundation for GUIs

The foundation is a text with attributes — a pair of a string and a map from string’s subranges to key-value dictionaries. Attributes express presentation (color, font, text decoration), but also semantics. A range of text can be designated as clickable. Or it can specify a custom keymap, which is only active when the cursor is on this range.

-- An engine for an editor

Unlike full HTML, the text is not nested, and logically is a 2 dimensional grid of characters. This makes text navigation universally applicable.

Unlike terminals there are multiple text buffers. You can have several apps running at the same time and displaying a text buffer each, or you could have a single app that owns multiple buffers.

Buffers are arranged in splits and tabs. Applications have limited control over the spatial arrangement of the buffers. It is the user who chooses which buffers are displayed in the foreground.

📝 ‹Programming› 2025 - Workshops - ‹Programming› 2025 via Jonathan Edwards

🧵 conversation

Please consider holding a workshop at 2025. Those of us doing independent research on software sometimes feel like we are rejected by academic computer science because our work doesn’t have the proper shape. In turn we tend to dismiss academia as a dysfunctional status game. Workshops are a way to bridge this divide between independents and academics. Since workshops offer little credit towards academic career advancement they are less subject to gatekeeping. The conference is particularly open-minded about the form and content of its associated workshops, with a pronounced fondness for the softer and more human aspects of programming. attracts researchers from diverse fields with open minds. Please consider this opportunity to enrich your community by engaging with both independents and academics at a workshop.

The conference will be in Prague, with the workshops held June 2-3, 2025. Further details are in the Call for Proposals. I’m happy to answer any questions.

📊 Towards Reusable and Reactive Widgets for Information Visualization Research and Dissemination via Jasmine Otto

🧵 conversation

👀

A Reactive Visualization widget displays data and allows users to directly interact with it (e.g., select a bar in a bar chart 📊). It then emits events based on these interactions (e.g., signaling which bars are selected).

The paper presents several usage examples of the pattern, templates for implementation, and even a wrapper for facilitating the conversion of any

Vega specification into a reactive widget.

📝 A text editor that supports doodling by Kartik Agaram

🧵 conversation

A text editor that supports doodling.

Some previous ways to have text coexist with a canvas:

• A fixed background that is disconnected from text.
• Fixed page boundaries.

Here I'm instead attaching doodles to a pivot character that they move with in the presence of edits. When you start drawing you're presented with a set of pivot options, one grey square per character on screen. After you pick one, it turns pink and the other options disappear. Now you can start drawing.

Displacements to the pivot are preserved in font-derived units, so it looks "reasonable" as you resize the font.

Deleting a character deletes all drawings pivoted on it. (But there's undo.)

This took 200 lines, so not too much though it was more than I'd initially expected.

Inspired by this thread.

(Where's everyone else? I'm feeling lonely in this channel.)

I hadn't tried this until today, but it turns out to work: I can create equations forwards and back, and trigger either selectively based on what blanks I fill in.

The fine print: to switch directions I have to fill in the right blank, clear the old blank, and then type in something outside the old blank (to indicate I'm not going to type further into the old blank).

Works better if I clear the old query first, but who can remember that?

Perhaps I should just recompute on every mouse click. Then the third step could be clicking outside any blanks. More wasteful, because most of the time a mouse click won't require recomputation. It's Tadi, but is it permacomputing? 🦋

🤖 Generative AI inside Github Actions via Scott

🧵 conversation

(I'll join in on the fun!)

I've been experimenting with using generative AI inside Github Actions lately and have been really intrigued by this async/event driven interaction model with code generation.

In this repo we have a Github Action that runs every morning and has Gemini, Claude, and GPT-4 generate a PR adding additional functionality. Then on PR merge a release message is sent to our discord with example use cases and each of them riff on what was merged and try to come up with additional related functionality.

I've already merged a few PRs and some of the ideas they've come up with are pretty interesting, especially the riffs - I merged a PR about querying a notion database, and Gemini came up with taking a row in a Notion database and creating an Asana task.

Some of the things they've come up with so far:

It takes two to think

Despite the variety of creative approaches practiced by different scientists, one tried-and-true though often overlooked — trick for generating new ideas stands out. It may sound trivial, yet it is as reliable as it is simple: talk to someone. By talking with other people, we not only pool the information or ideas that each of us individually lacks, but we are also able to improvise new thoughts that are not accessible to us alone. In this episode, Itai Yanai and Martin Lercher talk through the ideas in two of their editorials (available at nature.com/articles/s41587-023-02074-2 and genomebiology.biomedcentral.com/articles/10.1186/s13059-021-02575-w).

Naturalizing relevance realization: why agency and cognition are fundamentally not computational

This is a psychology paper, so perhaps not what you usually consume, but I want to encourage you to give this a go. I think it’s super useful to leave our bubble from time to time and learn about what other disciplines’ perspectives on computation are. I’ll quote the summary at the end, but there is so much more building up to that that you don’t want to miss, certainly not before commenting on it. :)

The view that intelligence equals some kind of computational optimization is no longer tenable. It does not help us make sense of a large world. Therefore, claims that the study of intelligence is converging onto computational rationality as its ultimate foundation are not only premature, but outright misguided. Quite the opposite: we have shown here that the basic foundation of natural agency and cognition, and therefore of anything we could reasonably call “intelligence,” cannot be computational at all because it cannot be completely formalized. The dream of generating purely algorithmic systems able to think and act like human beings is and remains a pipe dream, because purely symbolic machines exist in small worlds, in which there is no problem of relevance to be solved.

🎥 The Coronavirus dashboard on Kendraio App via Daniel Harris

🧵 conversation

Hi everyone! I just made 💬 #introduce-yourself@2024-09-30 and promised a glimpse of our work. We (the Kendraio team) are currently experimenting with no-code, local-first and malleable-software isms.

We want to create a local environment where it is really easy for end-users and non-developers to build workflows and manage their own data, whilst also being able to plug into the services (apps and websites) that they currently use and build their own user-interfaces for those services. It's a big dream and we've started small.

A few years ago during the pandemic we built a dashboard for COVID-19 data. Our Flow plugged into various APIs and then visualised the received data on one page – so a good demonstration of one aspect of our dream. The dashboard still exists but shows historical data. We wrote an article about the dashboard which also has an accompanying video explaining how it works and how you can edit the Flow while it's running.

Enjoy! Look forward to any comments or questions. Cheers!

📑 SPLASH via Thomas van Binsbergen

🧵 conversation

My students and I have worked on three papers (two prototypes) that will be presented at SPLASH at end of October

• Christopher Esterhuyse -- Cooperative Specification via Composition Control (SLE2024)

• This paper investigates control mechanisms in declarative languages that can be used by a programmer to have guarantees about the written program even when it is extended by other programmers. The work is motivated by distributed systems governed by policies in which the actors that provide the policies may have been competing interests. Concretely, think about (data sharing) contracts that are embedded in a federated cloud infrastructure.

• Damian Frölich -- On the Soundness of Auto-completion Services for Dynamically Typed Languages (GPCE2024)

• This paper investigates the use of "abstract interpretation" to give sound auto-complete suggestions for dynamic languages and demonstrates the technique on a subset of Python. Here "sound" means: if you select a given candidate, the inserted code will not contain variables that turns out to be undefined when the code runs.

• Max Boksem -- Bridging Incremental Programming and Complex Software Development Environments (PAINT2024)

• This paper demos a prototype that we built to investigate a modular graph structure for representing and running source code. The tool allows you to create different projections out of the code such as code structure, documentation view, and execution history. The tool supports incremental and exploratory programming and "nested graphs" (importing a graph as a node) for hierarchical views, although this is a more recent add-on.

Hey 👋 I was recently searching again how "usable" "AI" became. So I stumbled on this tool: pinokio . Its all just JSON. Before just evalutating the tool I might describe the criteria I would be interested in. Broadly speaking I would like to have tool similar to what we see in this clip: youtube.com/watch?v=HGYFEI6uLy0

Consider The following more specific scenario:

I have a PKM Zettelkasten and I have some friends. Now my workflow is to write and then to publish. I want to provide for them a Voice assistant that can summarize contents based on various parameters: By time e.g. topics of last 3 months, last week. But I also want to provide overviews on specific topics as well as interesting interconnections.

Do you know of any tools that could help with creating such use cases?

💬 Tomas Petricek

🧵 conversation

This is a very random thought - but something that I've been occasionally wondering for some time now. If we have lambda calculus as a model of functional languages and Turing machines as a model of imperative languages, what would be a good model for programming systems that have "document" as the basic underlying structure (Subtext is an example of this) - i.e., you have some tree structure and the program evaluates by modifying this document - appending new things or rewriting evaluated bits. (Lambda calculus itself is basically a tree, but what if this also allows imperative document edits?)

Could this be something like a "Turing machine" that works on trees rather than tapes? There would be "current location" which can move in various ways around the tree and modify it. If your document has references (perhaps you can have ../../foo to refer to foo of a parent of a parent), the machine would have to somehow walk up the tree, remembering that it wants to copy a value back to the original location - and then walk over the tree back to put the value in place of the reference).

Is this something completely silly or something that lots of people have already done but under different names?

It took a couple of days but I've now completely rewritten my parser so it can serve both for display and computation duties. Displaying requires keeping track of spaces. Computation requires detecting invalid statements.

Now 💬 #devlog-together@2024-09-18 can perform computations in (indented) code lines.

Still missing: synchronization between code lines and prose lines. The screenshot for example shows me redundantly defining ice_kg = 2 to provide it to code lines. Also, heat_flux is computed in code, but not yet filled in the blank space in prose.

I'm continuing to accumulate design principles:

• (generalizing from before) Everything is visible and easy to discover, whether it's the formula for a blank or the syntax to define a new blank or how to change colors. Any pattern you see on screen is easy to copy with the keyboard. (The one exception right now is the use of | characters in blanks and / in code. Both turn into horizontal lines.)
• What you typed in is saved in the document -- except what you put into blanks in prose. Blanks are not saved, but can override default values defined in code.

Hi, this weekend I spend a lot of time tweaking and improving some stuff under the hood of Code Flow Canvas.. and I finally started building some unit/integration tests for the runtime flow engine as I want to reliably know when a flow is finished. I found some situations with certain node-types (the map and foreach node-types) that had some bugs in it that I didn't notice before. Also when the flow-engine was used in a none DOM environment there was a nasty bug somewhere deep in the system which caused nodes not to be reached... building tests for this really helped and save me some time debugging. All of this is important anyway but especially for the demo that I will give remotely at Live this year, because I don't want to surprise myself and anyone else 😊...

In the attached screenshot you can see a new flow example that I made and hopefully make a video of next week: the K-Means clustering algorithm including visualisation of the clusters and centroids. You can already try it on demo.codeflowcanvas.io (it's in the examples).

🔮 The Future of Programming Systems - four thoughts via Jouke Waleson

🧵 conversation

Not sure if this is the right place to post this and whether this is interesting to this group, but I gave a short presentation last week about the future of programming systems and curious what you think about it. I wrote it down in a blog post here: blog.waleson.com/2024/09/the-future-of-programming-systems-four.html

There are four thoughts that I think will shape the future:

• Software development systems have a lot of vestigial parts (left-overs from the way it evolved)
• Understanding is crucial to development, and with the right mediums we can understand the subject much faster
• Most software platforms developed bottom-up, from the silicon, instead of focusing on the needs of the people
• Software is truly different from other technologies in the freedom it gives us, so we can and should invent new abstractions that make things simpler than they are now

This isn't in the post, but I think that in the future we'll see:

• Great integration between design tools, version control, IDEs, databases, monitoring & logging systems.
• High-level concepts as first class systems in the programming systems. Simple examples are an email or phone number type as a database primitive, instead of strings.
• Better reasoning / business logic rules so that IDEs can give feedback on "you are not allowed to store PII in this database".

This way all stakeholders can collaborate and the system can check correctness much better, and we require less discipline/in-depth knowledge from the team members.

I suspect most of these ideas have come by in this community already, but still curious what you think!

I've been looking at programming by demonstration recently (somewhat inspired by Pygmalion). There are some nice recent examples of using PbD for things like data wrangling (clean up data, extraction, etc.) and I know some examples for visual things (bar chart) - but I was hoping to use PbD to create something like TODO list app - do people in this group know if there are any systems (recent or ancient) that do something like this?

I actually have a prototype where I can construct adding of new items to the list using PbD (you do a sequence of actions to create and add an item and then you can replay that), but other things are trickier - e.g. to count checked items or to remove items that are completed, there needs to be some way of parameterizing the actions (so that they can be applied to all items) and specifying pre-conditions (so that they only apply to certain items) - I'm really not quite sure how to best do those...

📝 Conway’s Game of Life implemented in PURE (no scummy Apps Script) Google Sheets via Mattia Fregola

🧵 conversation

(also related my – admittedly less dynamic – Cellular Automata Google Sheet)

💬 Robin Allison

🧵 conversation

Hey future of coding folks,

I want to advertise the idea of non-abelian spreadsheets. The idea has slowly drifted into the center of my thinking this last year. I'm not sure if its a good idea or not. It kinda depends on how you build on it. So for now I just want to convey the general idea.

Picture in your mind a normal spreadsheet. In some sense it is 'abelian' (commutative) because from any cell going down and then right is the same as going right and then going down. If we make it non-abelian, so the order we go right and down matters, we get something like the picture attached below.

If you tilt your head slightly you may recognize it as the infinite binary tree. So an infinite binary tree is just the non-abelian version of the usual grid-based spreadsheet. The nodes of the tree are the cells. We can also think of finite binary trees as the analogue of tables.

A key feature of regular spreadsheets is the ability to write formulas with relative references. For instance in a regular spreadsheet you can use relative references so a formula always refers to the cell to the right of the given one, and in a tree you can write a formula that always refers to the cell you get by going down and to the right from the given cell.

Another key feature of spreadsheets is that you put stuff in cells! And we do that with trees all the time. For example if we write down the syntax tree for (a+b)*c what we are doing is putting each of the symbols into a cell of the tree.

We can push this analogy to account for all trees (in particular all syntax trees). This tree can't really be visualized because it branches infinitely at each node. It is much easier to describe algebraically. I'll use the term 'free monoid on a set X', which if you aren't in the know just means the set of strings made out of the elements of X regarded as distinct characters. The infinite binary tree, or more precisely the set of nodes of the infinite binary tree, can be described as the free monoid on a two element set {L, R}. e.g. RLL describes the node you get by going right, then left, and then left again. Now let X_n denote a set with n elements and X the disjoint union of the X_n for all n. It suffices to take the free monoid on X.

A reasonable question at this point is what is the interface for an infinitely branching tree? You would think it is even worse than an infinite dimensional grid, which is the abelian version. But if we are restricting ourselves to trees coming from symbolic expressions then for the most part we already have the interface. It is just the symbolic expressions we would have written down in the first place.

I'll leave it at that.

Turnstyle is a graphical esoteric programming language loosely inspired by Piet. Both encode programs as images, however, the similarities end at the syntax level.

Where Piet is really a stack machine in disguise, Turnstyle is an encoding of the (untyped) Lambda calculus. This allows for building more reusable images at a higher level of abstraction, while still keeping the specification small, making it relatively easy to develop new interpreters.

Turnstyle is an graphical esoteric programming language based on lambda calculus.

Hello! I just listened to the AgentSheets episode and wanted to share that I’m working on a PBE + block programming educational tool. It’s a work in progress but the vision is of something like “a macro recorder for Kid Pix” that lets you switch between drawing and code editing. motifdesigner.netlify.app Target audience is elementary school age kids, though it’s also meant to be fun for adults to tinker with.

I’m excited that there seems to be a bit more traction (or at least interest?) around PBE again. I thought it was an interesting point in the paper/episode that it hasn’t necessarily gone out of fashion because it wasn’t a good idea, but because other solutions emerged to some of the problems it was trying to solve.

... Chipping away at articles regarding a bunch of experiments towards creating higher level syntax for programming languages. Thus far, I've managed to consolidate t2t (text-to-text transpilation) into a single .mjs file and to redocument it. Wrote an adjunct article about experimenting with "t2t" using a toy meta-programming language to generate code in existing languages. "T2T creates DSLs. T2T reduces the amount of work required to build a DSL. You should be able to create a new DSL in an afternoon. ..."

Very initial draft of a notebook UI.

There are 2 kinds of lines here:

• Regular lines are prose, but you can also insert named blanks into them using the syntax [value|name] , which renders vertically across 2 lines. You can't nest blanks within blanks. These lines can wrap, but a single blank can't wrap across multiple lines on screen.
• Indented lines (though the indentation is currently subtle) are code. They can render fractions using the syntax (a/b) as I showed before. (Not sure I'll keep this in the long term.) You can nest fractions within fractions. These lines don't support wrapping.

Planned:

• synchronizing blanks with the same name
• using code in indented lines to compute derived names without values inline.

Inspirations:

• Kragen Sitaker's bicicleta
• Jonathan Edwards's Subtext 1 (💬 #linking-together@2024-08-29)

Today I've added some rudimentary styling syntax to my notebook.

It looks like I care about always making the styling very transparent, so it's possible in principle to guess what characters one needs to type to copy the look of something one sees on screen. So the style directives will never be hidden.

There's a bug in my parser. Here's a debug UI showing it at a glance. The parse tree in the background is for the line the mouse pointer is hovering on.

One fun thing is the couple of lines in the middle there. I reached for a notebook to scribble some equations for myself, but then realized all I wanted was to be able to draw the fraction line horizontally -- and I'm sitting in a tool that can do that.

🕸️ 1992 mailing list post from Tim Berners-Lee via Ivan Reese

🧵 conversation

A fascinating 1992 mailing list post from Tim Berners-Lee where he briefly outlines his desires for a programming language for the web — basically, what JavaScript could have been.

The principles of hypertext are on full display:

You need something really powerful, but at the same time ubiquitous. Remember a facet of the web is universal readership.

Then there's the PL nerdery:

Ideally, the language should include object-oriented inheritance, a basically functional nature, and a clean syntax. It should be interpretable and compilable. At least one public domain. A pre-compiled standard binary form would be cool too.

My favourite bit, though, is the desire for the client/server to negotiate over the language of the executable document, just like they negotiate other details. There are some wild isomorphism implications here.

In reality, what we would be able to offer you real soon now with document format negotiation is the ability to return a document in some language for execution, with the option of being able to provide it in several languages, the language being a "data format" which can be negotiated between client and server at run-time. For, for example, one could provide it in viola script and/or in /bin/sh which would cover most ofthe unix world.

Greed for power, for status, for money, for control.

Very early days (and not as innovative as a lot of the things I see on here), but I started working on a vscode extension that takes some ideas from semantic editing to build something sort of vimlike but that has things like functions, parameters, etc as first class ideas so you can e.g. press f to select the nearest function, press q to go to parameters, and then press a to append a new parameter at the end (which adds a comma and space, or newline and space, or whatever, and then drops you in insert mode) Here's a little video if you're interested

🧮 HowMuchIs13BillionEuros.com via Declan

🧵 conversation

Hi all, I made a page to contextualize 13 billion euros (or 14): an amount owed to Ireland in an EU Apple tax case and all over the airwaves here this week. I use some pretty silly back-of-the-envelope type calculations (the same ones also repeated a lot here this week!).

These calculations aren't especially interesting, but I think I'll use this example to illustrate a close link between numbers: the type that we read and report about everyday, and their formulas/workings - because all numbers have these.

Here you can also change numbers in calculang (e.g. change that 13Bn to 14Bn) and related numbers on the page will flash with updates.

I was glad of this exercise to focus on something a little more relatable to a simple spreadsheet, but portable and structured in terms of calculations imo, unlike a spreadsheet.

And I needed to face a wee small bit about the pains of finding data, and even afterwards: "linking" to it 🤒 (i did a lot of c&p hardcode :dotted_line_face:)

The page is: HowMuchIs13BillionEuros.com

It’s a basic micro platform that auto-generates customisable graphs from csv your data files, it then renders an embeddable web component and we’ve used echarts, which we’re very happy with.

It took us one month to build it and another month to ship it, (highlighting a potential opportunity in AI deployment infrastructure). We’re rolling out new features weekly like a filtering settings, improvements in the AI Engine or pulling data from Notion DBs directly, we’re gathering user feedback to refine the UX and functionalities if you use it and like it/dislike it let me know!

💬 Jason Morris

🧵 conversation

When I started my law firm, I thought everything I knew about a client matter needed to be in "the file". I wasted a lot of time moving things that were perfectly fine where they were. I realized that "the file" was a naive metaphor I took from law firms pre-cloud. That changed my outlook about data models. I don't want my digital model of things to mimic the real world artifacts involved, and spend a lot of time trying to explain to my colleagues that just because a person files a motion by delivering a real or digital pile of pages with real or digital ink on them doesn't mean that the document and the motion are the same thing. A motion doesn't have a page orientation, and a document isn't potentially vexatious. But when I argue that we should be modeling the domain, not only the artifacts, my colleagues — who are all also former lawyers — don't seem to disagree so much as act as though I'm speaking heavenly script. Does anyone have any tips for persuading people who haven't been converted to the wisdom of domain modeling that maybe our systems should deal with the things we care about, and not only the things we can download or touch?

🍰 The main ideas behind Hest are... via Ivan Reese

🧵 conversation

Reposting ;)

Periodic self-reminder.

The main ideas behind Hest are:

• Nobody’s made a good computer code out of things moving through space.
• Moving through space is also about moving through time. Rewind is table stakes.
• If moving through space is meaningful, then space itself is part of that meaning. Position, distance, velocity — they mean something.
• You can do things with this meaningful space-time visual code that you simply can't do in a non-moving visual code.

🤔 Are there languages that emphasize the single-datum <=> collection-of-data duality? by Beni Cherniavsky-Paskin

🧵 conversation

Are there languages that emphasize the single-datum <=> collection-of-data duality? E.g. making loop-with- if <=> filter -on-the-whole look very similar?

But that's just a programming curiousity; I'm more interested if there are any mind bicycles that help one think about local vs. global rules?

Physics is rich with examples where seeing both perspectives is insightful:

• local F = ma <=> conservation of potential energy independent of specific path (for certain forces)
• Gauss's laws relating single-point "differential" <=> volume/surface "integral" formulations of Maxwell equations
• Noether's theorem is certainly up there, relating shapes of laws with conserved stuff, but I'll admit over my head...

Example task: For a while now I've dreamed of making a model of weather that's simple enough for paper+pen+tokens, or generally something "board game-ish". Lies-to-children are fine, but would like it to demonstrate at least basic mechanics: (A) wind caused by hotter air rising and leaving a vacuum; (B) evaporation over sea => rain over land (C) "rain shadow" beyond a mountain (my country has this).

It's not easy to discretize continuous-quantity equations into something like a cellular automaton... I'm leaning towards representing conserved quantities like water with tokens you can move, rather than per-cell state.

And I don't want some huge "simulation"—I'd love to find rules that can demonstrate these processes in few enough steps to follow by hand.

Hmm say I have air that wants to go up + right, and it holds just 1 water token—which way do I move it? Well I suppose I want a bit larger numbers so quantization won't matter that much... And I probably want alternating horizontal vs. vertical game phases (also dealing with 1D slice at a time can reduce previous-vs-next-state confusions).

Any advice for tools to help think about rules/mechanics and what can emerge from them, beyond "try and see what what happens"?

(But I guess I really should play with large "sand" style models, then try to scale down! try-and-see is more powerful than merely keeping in my head.)

There might be a turnkey solution for making inline canvases as a Jupyter extension. Good luck identifying logical objects, but there must be some advantages over drag-and-drop.

For any other paper tool, diagram, nonlinear algebraic notation, what have you, there is a lot of potential.
