Leptons looks like it’s single allocation at construction instead of per render like Solid but done in Rust. Must be fast as heck, assuming webassembly to JS marshaling is efficient. I’d guess it has the granularity like Solid to patch only exactly which DOM props have changed.

The framework Leptos for Rust has created a template on CodeSandbox! If you want to play with a Rust web framework that feels familiar with React, this is a good place to start

Val town is the pragmatic instantiation of my favorite ideas in Unison Web, Darklang, & other future of coding languages. I’m very bullish on environments with certain invariants/constraints but using an existing language instead of a new one. JS/TS is the logical choice.

Francois Laberge - Playground AI

Do these people look frightened? Definitely a little, but nothing I could tell a good story with.

Results for "uncontrollably angry" aren't exactly that bothered. They look more like they are doing stank faces.

Crying was a total no go. Couldn't get a single tear to show up. These are 2 sets of results. One set has only subtle sadness and realistic faces, the more anguished versions are pretty borked.

Generating laughing humans was easy. Here were the first 4 results.

I started off my study by trying to generate one of those reference grids of human faces. The type you show kids when explaining emotions, like in the first image. But the results were total monstrosities, so I switched to trying to get single faces showing a range of feelings.

It's easier to get AI to generate a blood soaked face than generate faces showing strong emotions like crying or anger!? 🧵 Is anyone doing good work with generating emotional expressions with AI? I'm using

Full disclosure, I've never put in the proper time to learn Rust. I just fantasy read the documentation and every few years setup the tools and then don't stick to it. Zig felt more comfortable from my experiments with it, perhaps being less divergent from my comfort with C/C++.

I know everyone is using Rust for their Webassembly these days, but Zig is looking real good to me for ergonomics & simplicity. I'm ok with my code only running within wasm, so mem safety matters less, no? *expecting

@rikarends

to eviscerate me in comments for bringing this up*

I've been working with Webassembly more lately. I forgot how much much I enjoy working in a systems programming language. After 15+ years doing mostly web dev, I still can't shake the discomfort of how inefficient everything is.

You know you are too obsessed with infinite-canvas-based creative tools, when you updated your OS for a new app that required it, then updated 2 more devices’ OSs so you could see the UX decisions for each form-factor. apple.com/newsroom/2022/ Interesting so far & odd/quirky too.

Rumors are Apple is at least considering letting other browser runtimes on iOS. This would be amazing. It blows my mind how many users in comments actually don't want this to happen. I'm not sure how many people would actually switch browsers given more >10years using Safari.

in case you were interested in adding Typescript to Natto's editors. Perhaps you've already explored this or don't want to. Here's a good starting point either way

I'm working on getting full Typescript type-checking/auto-completing/etc running in @convey_it, integrated with the existing Codemirror editor I found this jewel from Observable's blog. Thought I'd share it with all you web-based programming builders.

Bringing the TypeScript Language Server to Observable

Observable is now using the TypeScript Language Server to provide contextual editor hints. Software Engineer Duane Millar Barlow explains how it was implemented.

I built the start of a White-boarding app using ChatGPT today. I spent ~30 minutes of exploring to get to where it is. Here's a video of it in action, showing the code, and showing the transcript. Here's a write up with the live demo & the transcript gist.github.com/seflless/6929d

My new theory is that Harry Mack is running GPT-3 in the background. His ability to create and freestyle rap lyrics on the spot are inhuman. An example, 5 minutes straight of lyrics. I’ve seen 10s of videos of a similar caliber in the last year.

Working a lot with AR/VR/AI, you unintentionally build traditional VFX skills. What is modern movie VFX but mixed reality techniques with better tools and equipment. I should tap into this and make more videos. This insane video brought that to mind:

This is the most exciting web standards work to me, by far. Highly recommend watching it to learn about potential webassembly evolution. For starters: Module system, large improvements in the marshaling performance hit, and interesting set up for a many tiny processes compose

…also you need to consider: commenting systems, native vs web, device form-factors, offline (including full asset sync to device), and really all the anthropology of collaboration you should be deeply thinking about.

You have way more considerations than what cool CRDT/OT/etc, such as: permissions and modalities (private, org, sub-group, external, internal, public, maybe transient like a meeting ), branching type asynchronous merge (manual or auto). UX to reduce cognitive load is paramount

I gave it a try to ReSTIR paper by Nvidia, but only the Reservoir bit, not the pdf resampling. It's probably a broken implementation, but it is doing something for sure (it's most effective in 4k monitors and 120 fps): shadertoy.com/view/stVfWc

Here's a version using the proper method for recording what you are seeing in a headset. Really noticing now that I have tone mapping on the code editor which makes it look washed out AND mip mapping looks terrible on text (no surprise, will move to SDF fonts).

I can't be focusing AR/VR right now, it's not my priority, just thought I'd check out the new functionality. I've been future proofing my rendering system for this. Glad it worked.

Here’s a quick ⁦

⁩ demo of my WebGL Codemirror renderer. The start of supporting web based IDEs in AR/VR. This uses the new Passthrough AR Quest Browser functionality. Excuse the terrible recording, I only had 20 minutes today. Recording properly via cable soon.

Here's an old prototype I did while waiting for this announcement to support Passthrough AR in browser.

Anyone have any idea if stylus state/events/etc will be available to WebXR apps? cc

To be clear. ShapeXR is using an official feature for the controllers that now support a pressure sensitive stylus tip that you add to the stem of the controller. It’s not the most elegant solution, but it will help bootstrap AR/VR spatial pen use cases mixed with other controls

This was one of the more interesting announcement yesterday. ShapeXR here showing the ability of Meta Quest Pro controllers to draw on any surface in AR/VR. Early times & it already looks like it’s being put to good use.
