Testing standard.site integration for computational blogpost on Bluesky

Lopecode newsletter-001 Read all about the newest addition to a local-first reactive notebook environment that can be published to ATProto did-plc-j7nm3lrd5h7fm3sfhcv3lhfv.lopecode.com/r/newsletter...

✨ Atmosphere devs ✨ Bluesky is integrating Standard Site, and our initial work should be released in the next few days. Here's what that means for publishers and apps in the ecosystem: github.com/bluesky-soci... If you have questions or comments, please leave them on the GitHub Discussion thread!

the end of "parametric abstractions". A config menu, a set of arguments for a function, they are parametric. They have a certain specified configuration space. Its what we have always done. Its core to functional abstraction. With on-demand code generation, the space of programs is non-parametric...

Oh interesting. I added the computeNow ticks of the Observable runtime to the new debugger, and now I can see that cells that have a long compute time end up eating ticks from the runtime. Did not know that!

How hard would it be to replicate a community Slack installation to an ATProto lexicon so messages can be archived or sent to other application for indexing? Is there any community lexicons for this already?! cc @bmann.ca

Working on the next version of the temporal debugger for Lopecode. Now the "blocked" vs "computing" difference is colored, and the cells are topologically ordered so you see the cascades of computation much easier. Its already revealing a ton of unexpected inefficiencies!

Worked on getting themes reactive which was oddly satisfying. My favourite is ocean-floor

My experiments with hosting notebooks on atproto. The Ledger notebook lets you manage your notebooks and cross-post them, like I did just now!

It used to annoy me that Safari and Firefox would surface bugs that chrome did not have but now in my wiser years I am thankful there is divergence and multiple vendors for such an important technology as the web. The bugs are fixable, ecosystem capture cannot.

We are having some fun in the malleable systems forum collaboratory forum.malleable.systems/t/collaborat...

My agentic setup - YOLO but safe: safehouse to sandbox on native MacOS sandboxing whilst giving agent docker/Playwright access etc. - virtual monorepo: top level dev repo submodules in code and 3rd party repos - parallelism: worktrees from submodules so PRs don't mix Used at work and home

The idea that LLMs are bringing forth a new age of malleability, particularly through vibe coding, is a co-option of what malleability has historically meant. It achieves similar surface characteristics without the restructuring of power and literacy historically EUP advocates aimed to challenge.

Really enjoying the possibilities atmosphere unlocks. Login from a file:// domain, publish to atmosphere, or open via web link and login there instead Same identity, different mediums, same code. This sidesteps the control a traditional Cloud service asserts.

The sharing is what made Observable great. Lopecode's bundle-of-files representation maps *very* well to `at://`. I have a prototype notebook reader/writer tomlarkworthy.github.io/lopecode/not... uploaded to at://did:plc:j7nm3lrd5h7fm3sfhcv3lhfv/dev.lopecode.bundle/3mkjwz5coof2w

Thinking about moldability of SVG and how to achieve it without a ton of special casing or overt plumbing 1. leverage the computation graph you get for free with reactive programming 2. using numerical methods to manipulate parameter space from screen space tomlarkworthy.github.io/lopebooks/no...

Run Linux in a file? A 6.8Mb HTML self-serializing literate notebook file that emulates Risk V and can boot an interactive Linux BusyBox shell. Built differently (but heavily inspired by) Fabrice Bellard's JSlinux. tomlarkworthy.github.io/lopebooks/no...

What a time. I am now interviewing my LLM on its coding preferences.

A simple local-first solution to secrets tomlarkworthy.github.io/lopecode/not... Generate an AES key, and write the secrets back into source code. Now the secrets follow self-serialization, they can be put on the web, but stay private to you. Full explanation in the literate notebook.

Computational blog posts that you can connect directly to Claude Code tomlarkworthy.github.io/lopebooks/no...

Woah, with Claude Channels you can proxy Claude Code. It combines really well with Lopecode's local-first reactive computational notebook approach. CC does web research, file modifications, git pushes. Lopecode provides a sandboxed visual fast-feedback hot-reload computational medium to jam in

Lopecode gzips and b64 inline modules, but does not minify so debugging works with nice stack traces and no information is lost during self-serialization

Well claude code inside with Lopecode was immediately fun with my kids

Proxy a conversation to Claude inside another app with `--channels`

Great times at Substrates 2026. Lots of inspiration. I got Claude Code working with Lopecode! It got Zig compiling WASM code in a 7Mb single HTML file (no network! works on file:// domain, no local webserver!). tomlarkworthy.github.io/lopebooks/no...

Seeing if you can publish a notebook directly with leaflet.pub Not quite, but it looks good if you follow the link. Maybe a consequence of clientside rendering but it might be fixable (without prerendering)? Cool though, I would like this to work leaflet.pub/p/did:plc:j7...

I do think one of the most significant developments in computing in the last decade (apart from ~that~ one) has been the computational notebook. Browsing through my @observablehq.com notebooks, they capture my visual and computational thinking more effectively than anything that preceded them.

The user/developer divide I think comes from compilation is a one-directional process. The user receives an artifact they can do nothing other than use. Free Software suggested source needs to be included, but it be operationally simpler if the artifacts could just decompile themselves.

I have been using git as a representation of history. The staging index is for workflows. Its state that can cause bugs. You can do commits directly with blob → tree → commit And read files without checkouts commit → tree → blob directly on the git database statelessly. Useful.

git submodules are amazing for bringing upstream dependencies into AI context and iterating on interactions. You can even test and launch upstream patches.

The JS Realm thing came up because I am testing Lopecode by serializing itself into an iframe, which is quite convenient because it reuses all its self-serialization machinery and somewhat isolates itself. Perfect for destructive testing, easy to restart from a known state.

TIL: Javascript Realms. Things I took for granted like `isinstanceof Promise` don't work across "realms", e.g. a Promise across an iframe don't think they are the same thing object. Furthermore, the microticks are not interleaved and new bugs can appear.

More tremendously meta of putting another lopecode document in an iframe inside another. The idea being I get trivially resettable isolated runtimes for testing and training.

Finally cleaning up some long outstanding issues. Imports are rendered properly with hyperlinks! Had to fix the decompiler, the cell grouper, the visualizer and the URL system to get those working. But they finally work at last!

This is an act of cultural vandalism: zombo.com RIP zombocom, 1999-2026. You could do anything at zombocom. Anything at all.

I remember this at the time (2008) but it is so much more relevant now. Are you a Cosmist or a Terran? www.researchgate.net/publication/...

funny, I am testing an agent on moltbook. Its strange seeing the AIs jam off each other. They nephesh. www.moltbook.com/post/723529a...

I have a claude code command at work called babysit_ci, that analyses the Actions log and if looks like a flake (DNS, provisioning, networking etc.) reruns the task, polling every 1 minute to check status, max 3 retries per task. Annoying we need it but it has got us back to fire-and-forget PRs

proud to have got a low level bug fix into Notebook kit! github.com/observablehq...

Fixed a bug where patching the runtime source would not propagate to other editor types. In a normal app you would "thin waist" everything through one mutator function, but as Lopecode is extensible and radically decoupled, each has to react to the runtime without knowledge of the other.

0 Days since noticing a subtle DOM observer bug. I think I might be quite close to parity with Observable semantics at this point though, the bugs are getting more and more subtle, and the runtime is getting faster.

Whole Notebook generation with Robocoop! Bloody hell. It can 1-shot whole notebooks and use dependancies as guidance.

Jesus Christ with the new 5.2 GPT it can reliably 1-shot generate whole notebooks. I have a new methodology for prompting Robocoop that takes it to the next level.
